SuperCharger Wars!!!!

[cyclone03]

First take note of the smiley!
With all the talk of who's Forced Induction is better at what.
I figured with respect to both Dennis and Trilogy to take this off of their pages.
I agree with SgtMac about slamming one guys product on his own page being wrong.

So heres my take.
Roots:IMHO packages better.It sits on top ,or in the "V" so theres no extra brackets about to hold it's mass.The OEM's like them for that,the power plant goes in in one step.
Know more as a LOW END type power adder,Below 5000rpm.
Hits from the touch of the throttle.
The bad?Know for high power absordtion,the old one anyway.They beat the air up,increasing charge air temp.
Now the way to get around that is with after cooling,IMO the only way Ford gets by with them on the Cobra,"L",and Harley.

Vortec/centrifical.(with roots way back to the McCulock/Paxton of the 50'sBTW.Did anybody here know the guy who started Vortec at one time worked at Paxton? )Basicly started as the COLD section of a Turbo,then gear driven:
Packaging for OEM's a real PITA.Brackets ducting maybe an extra belt.Too many moving parts for them.

Us,the aftermarket.
Vortex fits anything just make the bracket.Know for a lower HP drag on the engine,cooler discharge.Easly to fab aftercooler for more power.

The truth with all of this is in the TUNING! Theres also support equipment required for both in ,injectors,fuel pumps,mass air metters,by pass valves.Then down the line ,headers,exhaust,torque converters,gear.the list goes on,how fast do you want to go?Pistons,Cranks?

Personaly I like the Trilogy because of the OEM look.But I feel the Vortex will Run faster at the track and can easley be pulleid to blow the bottem end out of the Marauder.
Day to day stop and go,I think the Roots would be more fun,they always say they feel Big Blockish.Ive never driven a roots blown anything.
I have driven Vortex blown Mustangs ,as a matter of fact I did one of the first installs here in San Antonio. Just driving around you never noticed it.At about 3000rpm well.....oh yea here we go....I talked a good friend into putting one on his Big block Dualy Chevy.He ended up having production kit #1 put on at Vortex,his truck ran like a stocker until 2500rpm then Lit Up all 4 rear tires!Very fun to drive.He put over 75,000 miles on it and used 3 belts.His kit only made about 7lbs of boost.Same friend has another Vortex on his V10 Ford!I haven't riden in that one.
That 2000-3000rpm hit is why vortex are known to be a little easier on the engine.

Now for the war.(put big grin here!!!)
Dennis' car already has headers, exhaust and gears(I think) and is getting a converter (again,I think) so to run his car against the Trilogy car head to head would not be a fair(if there is such a thing as fair)comparesion.The Trilogycar CLAIMS to be stock except for whats required to allow the engine to live under boost,tuning wise only(injectors pumps etc...).
So power wise Dennis has the deck stacked in his favor.On the TRACK I THINK Dennis would win anyway.The Trilogy car has run,what,12.80's?My GUESS is the vortex would run lower 12's.

The BIG ?????? for me is who can run that power adder the most MILAGE without blowing up the bottom end?

AND what about the oil pump right behind the lower blower pulley is it going to take a little more VIBE's due to the SC?

I would like to see a lower pulley support as installed on the factory superchaged engines,this may be an area overlooked for durability by our after market tunners.
Ever seen a lower pully/crank end come flying out from under a car at 6000rpm?Trust me it aint pretty.

Ok theres my say on Supper Chargers.
:flamer: a way!

Note I did'nt say anything about using turbos because then the war would be over.:flamer: on that one too.

Lexus and Mercedes have small displacement V8 engines (anything less than 350 cubic inches is small by my standards} that produce Hp/ torque and decent fuel economy without the need for any kind of forced induction, they use variable valve timing to produce more hp. without blowers or large displacement blocks. I love American cars in general and Ford in particular, and it really bothers me that we build right here in the good ol' US of A the finest combat machinery known to mankind but we cannot match inch per inch, horse per horse what others make.:mad: :mad: :mad:

[rumble]

Smokie you are correct about Lexus and MB, variable valve timing etc. But supercharging is the "nuclear option". Nothing, but absolutely nothing comes close to increasing power over the
long term. Supercharging can increase RWHP by just about whatever you want or your engine and drive line can stand. Modest boost, say 5Lbs or so seem to have little effect on engines going 100,000 miles yet give a significant increase in power. In the days before computers, it was wild cams, high compression pistons, multiple carburetors etc but when "blown: cars rolled on the track they were made to run in a separate class because they were that much faster.

[Smokie]

RUMBLE You are completely correct about the effects of s/c on horsepower and torque, just like nitrous oxide produces on demand huge amounts of power. The point I was trying to make is that there are car companies today that produce normally aspirated engines in the displacement field of the 4.6 liter that produce significant greater amounts of horsepower and torque "today". I believe the reason that our friends on this forum are going to chips, gears and s/c is because Ford apparently is not able to produce the torque on this engine that we all wish the car had without mods. I love the car, it just bothers to know that other companies can get so much more power out an equivalent size engine.

[Marauder57]

Personally I like the Vortech option from Dennis...installed by Dennis. He does a great job and tunes it perfectly...his standards are very high....for me that is the only one I would consider.....if any....but I have seen it up close and personal....and I will be interested to hear the comments from people as they see this masterpiece first hand.

Basically different strokes for different folks.......my biggest thing for me at least would be...I would not buy a kit designed by someone else and have it installed by a different person. If I want Mona Lisa, I want DaVinci painting...not DaVito. So when I wanted Stage 1...I went to see Dennis at his shop....For people in the Midwest or other locals...Trilogy or Kenny Brown...are what they feel good with.....

I can tell you this....and not to start a problem or place undue pressure....but I would love to see SC cars from all the manufactures on a track at Ennis. Maybe even head to head.....it would just be really cool to see 4 or so SuperCharged MM's screaming down the track.....we would all win there...and a great forum for people to check out the options......

I think I know a guy who might bring his MMSC...**Cough**, **Cough**, **SergntMAC**, **Cough**.. :D

[Menace]

I like the Eaton kit from Trilogy...installed by Lidio. :P
It is also tuned perfectly. :D

I like the idea of superchargers!

[MI2QWK4U]

I think Cyclone has some valid points in his post. The supercharged cars are not equal in the totality of mods. The Trilogy car is totally stock. I believe their intent was to show what just the Supercharger did on its own to the numbers. To be honest I dont know what is in the future for their car. Personally my plans call for a beefier rear end build up with 4.10's, studds, and diff girdle; the Eaton blower; a transmission tune up; exhaust work, widened rear rims and slicks. The suspension mods have been done already, and if you care about how this car handles, get the Eibach springs, they really help the car handle better at high speeds, not to mention the improvement in looks. I really thing that will encompass the major areas that can be improved on. And I will tell you this much, I will be happy to take on all comers for a head to head challange, more out of curiosity and learning about other setups. I am concerned with all the talk about blowing up the bottom end of the motor though. Can anyone elaborate on this? It seems to be a concern with whatever blower you choose. What are the major concerns and what is the reason for those concerns. The Trilogy car has been driven HARD for a few months without a hint of trouble. I do think it is nice having a choice though.....

[rumble]

Smokie we have all heard "speed costs money, how fast can you afford to go." I guess, wondering out loud that is, maybe the same thing holds true with manufactures in engine development and production. We have a 4.6 that makes 302HP, Audi has a 4.2 V8 that makes 320 but costs a whole lot more and so does Lexus and Infinity. Not to disagree with you, just to speculate. As this thread is about SC, just imagine (fantasize really) that FMC had
gone the lighting route with the MM? World beater? You
bet but try selling it for $45,000.

[TAF]

Frankly rumble, I think the MM is an excellent car for the suggested price and a steal at what some of you are paying now.

And, with a supercharger (pick your vendor) and other mods available...for less than $40K...I think you DO have a "World Beater". I'd put that up against a Mercedes sedan, a 7-series or an A8 anyday, and have $40K in my pocket for a spare one.

[rurumon]

Turbo? :D


Anyway, the vortech is a tried and true charger for the cobra block, no surprises here if it puts down real nice numbers, I just think its imperative that the kit from dennis include the aftercooler which seems pretty much mandatory if you want to run higher boost levels efficiently. Problem is the vortech blower kits come with the aftercooler as an "extra" that you have to pay more for, which wouldnt surprise me if the kit from dennis reflected the same idea. My question is why not try and make the procharger kit work? there is a procharger kit for the cobra motor that fits on alot simpler than the vortech blower due to its self lubricated turbine AND it comes with a 2/3 core intercooler for a price thats equal to the vortech. Im not putting any kit on my car without some form of intercooler, and I dont want to break the bank to get it put on......ideas?


As for a roots blower, its not going to give you the power a centrifugal blower will....period. So those of us who see 16+ psi in the future arent going to put down respectable numbers with a roots kit.

I'm glad you mentioned this, Dave, everyone considering a supercharger should get familiar the potential complications.

Whether roots or centrifical, both styles threaten a stock MMs long term durability when the boost gets cranked up. IMHO, both are safe up to 9 pounds of boost, but after 9, I see the durability/longevity scale tanking quickly. Chief worry is the effect of high boost on the stock 10:1 compression, and durability of cast internals. The MM does not have a Cobra engine, it's a design knock-off, so, it really doesn't matter much who put the car together, the stock engine just isn't strong enough to take higher boost over a long period of time. Neither can the power train take long term high torque, just wasn't designed for that. It's not a matter of fraility of the stock MM either, it's only common sense, and we should be aware of and respect the natural limitations of the whole car.

Two ways to approach this, one is to build your MM a mod at a time in preparation for the big power mod, or, start with the big power mod, and add what you want as you go along. Either way, you'll come to spend about the same, average out around 7500-8500 bucks. That will buy you one kick ass "bolt on" race car that's still a daily driver and quite manageable when Mom has to run to the store. In the end, the leader of the pack will be decided by driver's skill and little secrets.

That's why I find the Trilogy kit so attractive. You can start with a bone stock MM, add the kit with 6-8 pounds, and really enjoy the car. If you moderate your driving habits the Trilogy kit and the MM will be life long friends without any problems. However, if you get an appetite for more power, or come to charge hard on a regular basis, other stuff will have to be updated, or you'll suffer breakage.

The only flaw here, is that if you have pre-built your MM waiting for the power, you may have to re-think and re-mod some of your ideas. After riding in the Trilogy MM, I'm not sure 4:10s are necessary, but this is my early opinion.

I'm only being realistic here, unless you want to rebuild the bottom end, limit yourself to staying under 9 pounds of boost, and expect to top out between 425 and 450 HP. Otherwise, you may as well start ordering engine parts now...IMHO.

BTW, Jerry Barnes was supposed to take the Trilogy MM to Norwalk OH this past weekend, anyone hear any numbers?

I was going to pick and choose my comments but I ended up commenting on just about your whole post so here goes...

Turbos:D
I've got a local shop that does custom Turbo installs and they WANT my CAR! I just need to pay for the parts,Turbo $1500,Wastegate and controler$$,Intercooler$$,cust om plumbing including headers, intake and new exhaust,good deal I only have to pay for material,Stainless Steel BTW still over $500.
They say I should get out the door at around $5000.6-9psi to start,potental to a bottom end blowing 30psi.

Yes Vortex has had a Cobra kit for years now.When ProCharger came along with the cooler Vortex came back and said they're not needed,big war of words back then.But every body knows if you want to put down the best numbers you better get the boosted temp close to ambiant....

Roots blower not making power...HUM?
I would'nt say that,Trilogy at 12.80's pretty good power I think.
Now your right no way to get good clean,cool air from a roots over 16psi,but thats PURE race is it not?

I would think if you want to go to 10+ psi your moving into the "better build a stronger bottom end first"territory.Fringe race if you will.

What we have now are 3 blower option on the market now.
Kenny Brown.Vortex with aftercooler.
DR: Vortex with aftercooler-I have not called Dennis so i don't know whats in the complete kit.

Trilogy:Eaton with heat exchanger.


I haven't asked this of Dennis myself,but at least one other has.
Why not post the Total price of your kit?
As some have said I'm not ready to buy why do you want me to waste your time on the phone just shopping?

Trilogy?$$

I would say that what we have are 3 very good "street" kits.
Street now seems to be about 9 intercooled psi or 6 uncooled psi.

Lets keep this going.

Well, this sounds like you have a chance at a 1x MM of your own here, but it also sounds a bit experimental. Are you comfortable with that? The way I see this, Cyclone, you're right back up to 5K, and still a test bed of sorts. I wish you could get a ride in the Trilogy car before you decide on this. 5K for the Trilogy kit is a good "one-stop" start up for the novice/hobby minded that is pleasing as is. If you want to get seriously involved, it's Reinhart, Brown, or, VT and the centrifical designs. I don't know enough about turbo charging to comment further on that.

The Trilogy kit is intercooled, but I may be in error on the boost, it may be 10 lbs afterall, according to an article in S3.

Yes, let's keep this going, it's good for us as consumers, to exchange thoughts and ideas. Never was any sense to bickering over preferences. We should be sharing 411 to help each other, not make a contest out of it.

Turbos:D

Lets keep this going.

Agreed. From an engineering standpoint, Turbos are more efficient that SC's. There is no Horse Power tradeoff.

SC's can take up to about 10% of the gained HP to make HP. IE, if the SC could make 300HP extra, it would use 30HP to do it, so overall you gain ~270HP. As an example.

Turbos don't have that problem, but take time to build back pressure. Modern turbos don't 'lag' like older ones, and twin turbos solve that problem anyhow...but they are expensive!

Look at the Toyota GT-one road car. Something like a 2.5l inline 4, quad turbo developing 1000 and some horses. Oi!

All in all, - I think I'd rather go for the centrifical blower. Bang for the buck, and proven technology. But the sound of twin turbos sucking air!!! :coolman:

Sgt Mac I was waiting for your response here...........

Oh yea it's would be a one off for sure,It's not the testing,proto typing etc that holds me back it's $$$(and wife,and the fact I can't take the car down for the 30+Days etc....)
I'm sure you know me from my other post's so I'm not ready to take on all the cost that being without the warrenty would cause.


As far as tuning I've got one of the best within' 30miles.Any Mustangers ever hear of Mike Murrello?He know's a little about tuning a blown car. :)

Truth is I can't wait to see what shows up in Ennis...

[rurumon]

out of curiosity, what did the trilogy car dyno at when it ran 12.8's?

On another note, perhaps I didnt mean to say that roots blowers CANT make power, they just dont make it as easily as a centrifugal. And if I had a fixed limit of 8 psi, you can pretty much promise that the centrifugal blower is going to produce way more towards the peak, while losing only slightly to the roots blower in the low end. I believe there was a really fascinating article in Hot Rod last month where they tried three different FI applications on a 350 ci motor. They ran 9.5 or so psi through a roots blower, a centrifugal, and a non-intercooled turbo. The results, though not very conclusive....were pretty neat. It just seemed to confirm to me that roots will give you a slight edge in the beginning of the rpm range, but later on at the same boost a centrifugal will produce FAR more power.

I don't know HP #'s and I could be off on the 12.8 time a tenth either way.

A little more on the bottom goes a long way when trying to move 4400lbs from a dead stop.

The real #'s we need to see is the so called area under the curve.
say from 1500-4000 rpm,the meat ,well maybe not the power band but where the car seems to spend most of it's time.

[sailsmen]

I have owned a factory turbo charged Mercury XR4TI and a factory super charged Thunderbird.

The turbo retains so much engine heat that all the non-metal parts under the hood are cooked and have 1/3 of their normal life.

The super charger although it may have "robbed" more power due to being less efficient than the turbo did not reduce the life of any other underhood parts.

I owned both cars for 3 years and put over 55k miles on each.

I had a lot of turbo under hood heat related problems with the turbo charged car and no super charger related problems with the super charged car.

[MI2QWK4U]

Correct me if I am wrong then. The roots will give you the big time torque up front right away. The Vortech will give better results at the top end and outmuscle the Eaton eventually as you wind things out?

If that is correct, It seems to me that the answer of which setup you choose is heavily dependant on what your main goal is that you are trying to achieve ultimately.

I am just throwing things out here for you to think over and respond to. If I want to pull up to a light next to a Corvette, and want to blow his azz away up to 60 or 70 mph, are you better going with the Eaton roots style? Along the same lines, if I want to go to the 1/4 mile strip or maybe a street race that may hit 100+ mph, are you better with the vortech? Reason being the roots will give me the zoom right off the bat, but eventually level off, and the vortech will wind up and keep building up to its max.

I think we all agreed that the Marauder is lacking on off the line torque to get going. For me I want a car that will keep its daily driver status, but when a smug Impalla owner pulls up and sneers at me....I want to blow his doors off and be done with it. As I grow older I am a lot more conscious of the consequenses of insane speed...100+ mph, not so much worried about a ticket, but of either getting hurt or hurting someone else in the form of a high speed accident.

Please correct any misspoken facts above , I am getting the picture as to the applications of both setups.

As a rule thats correct,Roots has Bigblock feel off idle,Centrificle comes in about 2000-3000prm.

You could say the Vortex has a little softer "hit".

Now as for blowing off snearing SS drivers,or any others,it depends.
That instant hit "could"put you up in smoke off the line if your not carefull.

Now as for the vortex out muscleing the roots at the track,hum........ it depends on how far out the Eaton is before the Vortex starts the charge...........

The Vortex "may" help the tire spin but the 50ft it takes to start making real power "could"be your race on the street.

Mensera :bows: posted a story about beating a Vette in the infamous KB S #1Xray (now Sarge's). :beatnik:

It has a Centrifical blower. So, I'd say..no.

Daddy wants. Daddy wants bad. Come to Daddy, supercharger...

[FordNut]

If my reading on blowers is correct, the Eaton starts making power right off idle and the centrifugal blowers take awhile to wind up but then outperform the Eaton at high RPMs.

However, the Kenne Belle blower supposedly provides the best of both worlds. There is a retrofit kit to put the Kenne Belle on the Cobra, so when are we going to get one of these on a Marauder?

[sailsmen]

It is iinteresting to look at the engine NA HP figures to other makes and then to compare the SC figure of other makes.

I found the NA figures, if anyone has the SC figures please post.

"Frankly rumble, I think the MM is an excellent car for the suggested price"

TAF, you are right, of course. My thought was that those
Lexus and MB engines cost a whole lot more that our 4.6
and my point about trying to sell a Kenny B. style Marauder for $45.000 dollars is it would be hard for a car
company that won't even advertise what we have now and
sell them in any quantities for $35,000

[keyboardracer]

here goes my two pennies! One of the prior post hand mentioned tuning and having good driveablity. I live near Alternative auto and I see the trigolgy car so often I think someone is delevering pizza's in the car! I was at norwalk this weekend and belive the car was low 13's, thats pretty good. the weather was low 80's and there was alot of activity. I did not get a chance to see the triolgy car run. I have a friend who runs outlaw and that was keeping me busy. I think in a big heavy car which the mm is the eaton is the way too go. Tourqe is what makes the world go around and what makes a heavy car feel good. low rpm high tourqe motor will live a long heathy life. I can tell you in my experiance driving centrifical supercharged trucks, I would always preffer the low end grunt. I think it is time to get the kb car out to the track and run the triogy car. When can all type till our fingers are numb, the only way to prove anything is to take it to the streets so too speak. At the open house for triolgy, that car was getting the heck beat out of it. Jerry was smoking the tires like his last name was goodrich! :) I read alot of smack talk about how the kb car will do this and will do that. Triolgy and lido have put down 391 to the rear wheels and have gotten the car into the twelves. Actions speak louder than words, my choice when the time comes will be a triogly kit and a tune by a guy who has been proving what he can do for better than a decade now. ANy guy dumb enough, err I mean crazy enough to drive a 10 oh car to florida to drag race it has to have something going for him. I can also state as a fact if lideo thought the vortech was the way too go there would be a vortech on that car. He darn near ran a friend of mine out of his shop for wanting another make of blower out of his shop. I have not owned a mustang in a few years, but when I did alternative auto never tried to talk me into anything they thought would not work. They are not cheap but I awlays got what i paid for. Man this sounds like a paid endorsment!! lol I am gonna stop rambling now.

[Last Mrk]

Dennis Reinhart also has a 4,000# MarkVIII that he has a centrifugal blower on. Here's his timeslip from before he put the Cobra motor in the Mark.

So what I read/see here is when all is said and done, more will be said then done!

Texas my friends is where the answers will come from. We need/should have all vendors there and a track to see who got what.
