Place your bets, folks.

Lets see what this Vortech Air to Air can do. Now, I have the bigger pulley on it pulling ~9psi, so not big boost by any stretch of the imagination. Car getting badass fuel with a Kenne Belle BAP and GT500 fuel pump and 42lb injectors.
I'm gonna go with a race tune for the 100 octane to compensate timing, and a revs per mile change for the 16" M/T Drag radials. :D
The car on top of the blower has 4.10's and Kooks full length headers. Stock TC, my tuner is quite certain I would shave 3/4 seconds with the centi blower with a 3,500 stall. That will have to wait until next season.

The car weighs 4,150 with me in it, minus the spare, matts, etc.....
It's gonna be ALL in the launch.
Let me know what kind of numbers you think I'll pull with this baby.
Wish me luck, track rental day is this Friday. :burnout:

Here's my dyno chart with 93 octane conservative tune. I'm guessing another 20hp +/- or so w/the more aggressive tune.

Torque number looks kinda low.
Not trying to bust your bubble or anything, just sayin.
Maybe mid 12's???

[SMOKE]

I'll be there to see with my bolt-on, essentially stock Marauder...I'll just tell everyone we're using 2 cars...one for a baseline and one for the improvement factor yielded by your mods LOL....

Stock driver here too....never dragged at a strip. Going to be practicing my launches in my sleep tonite! ;)

Mid 12's sounds like a good projection. Wait till you put in a good TC, what a difference.

tq isn't low for a centri, if you notice it comes on a little late but keeps up, instead of hitting early then falling off, just the nature of the blower.
On another note, I did 110mph and 12.8 on street rubber back when I made very similar numbers. I could only manage a 1.88 60' with the street tires. With a good tire and good 60' you could do a 12.4 or 12.3 I bet

[Glenn]

Amazing difference when you compare a Vortech torque curve with a Trilogy SC curve. The Trilogy torque curve is almost vertical to max as soon as you launch the Vortech gradually builds over several thousand rpm.

Low torque will hurt your launches and result in mid-twelves at best.

Good Luck,

Glenn :burnout:

[Paul T. Casey]

Impalaslayer will run 12.37 @ 108.62
Jon (Smoke) will be pleasantly surprised with his 14.4's all night at 98ish.
Weather looks good, maybe a little humid (read that dewy) as the night goes on. High pressure and no wind should help. Who else is going? Dayum, I wish I was home now.

[Paul T. Casey]

Revision 1, forgot the 4.10's, make the mph more like 103.

[Paul T. Casey]

Jon, load that thing right up at the line. Try leaving at 1500 rpms, and mat it as soon as you take your left foot off the brake. If it doesn't spin, increase rpm next run by 50 to 100 rpms. Continue this until the tires break loose. You want a little squeak when you launch, not a long squeal off the tires.

[merc]

First run 12.79, lower on the second run. :flamer: on.

[2ndMDRebel]

My water-air Vortech'd CV with 4.10s and drag radials ran a best of 12.38 @ 109 or something like that with 438hp/404tq at 9psi ... pretty much the same setup as yours but I had a PI 3k stall converter.

I always launched from an idle, never loaded it up.

Thanks Paul! I trust your judgement....had ~2K in mind but starting lower and building is the kind of head games I was planning to play with myself. Shooting for tight RT's...I can pretty much assume what the 1320 will be...if I can get my adrenaline down! I'm soooo psyched....

Good luck with the car. Hope you can hook it up well. You'll be in the 12's somewhere.

:confused: How is ImpalaSlayer involved in this thread?

Anyhow, I'm skeptical, remember, i'm running LOW boost. a 12.8 would make my day to tell you the truth. We shall see........

I only run a 9 or 10 psi, boost has nothing to do with it if you are making power. Plus you have drag radials, you'll do a 12.8 easy, like I said I did a 12.8 with those kinds of power numbers on street tires.

[justbob]

I think low 12's with DR's. I run 12.92 @ 107 almost every run with only a stock Trilogy, never even on the dyno, probably around 375-385 ish. Now keep in mind i'm getting 1.7's in the 60 thanks to my DR's.

[FormulaMarauder]

Time shall see. Updates around 7:00pm Friday. Stay tuned.

[bob6364]

I say get 2 back to back runs in before the sun goes down because after that the track will goto poop quick.....

I think your ponytail is to tight Paul .... :D

[BODYMAN]

Youre #'s are very similar to my 1st Marauder it was a KB-S 436RWHP no stall 9.5lbs boost The best I or my buddy could muster out of it was a 12.9 at 111mph the no stall was killing it on the low end 60ft times. The Marauder I have now is a beast out off the hole a 3500 stall, it makes a world of difference.for us centri blower guys!!
BEST of luck!!!!

[Paul T. Casey]

I have a little inside info. FM went 12.9 in his first run.

My 12.79 prediction was pretty good.

[Glenn]

Experience has proven time and time again that a NA or SC MM cannot run good numbers at the track without a 3000/3500 TC. A good TC is worth at least 0.50+ second on the 1/4 mile.

+1 ON That. Gotta spool up them centrifigual blowers. Thats about what I saw 0.50 in my 1st MM

[DOOM]

Hey Glenn what do you consider good numbers?
With my stock trans & 3:55 gears
I ran 12.2 with a 1.70 60ft. SPINNING
Or are you just referring to centri blowers?

He just likes saying stuff that has no real basis, I do 1.88 60's on street tires, and have to half throttle out of the hole to do it. Centri cars come out of the hole fine, it's all driver mod/tires.

UPDATE WITH TIMES.

OK, well the track rental day was from 10-3. So Basically, it got hotter as the day progressed. There were about 30-35 cars there, and NO wait time. We could of put in 50+ passes each if we wanted.
My best run of the day was a 1.97 60' 12.702@110.13. I was prediciting 12.8, I was a nipple hair from a 12.6.
The car is lovin the boost, but wants a torque convertor BAD. I need some control arms too, should get me to a flat 12-12.2. All on 9 psi. Amazing.

Jon (Smoke) was racing like a superstar for a first timer. Got his groove on and got so comfy, that I threw him my keys. In typical rookie fashion he shut the car off prior to staging, turned it back on, and forget to turn off the TC and O/D. Still, he pulled a 13.1@ 98mph or so, and smacked the **** out of an 08 Vette. lol.

[bob6364]

Did you see this car?

[FormulaMarauder]

Yes we did!! HELLUVA nice guy, we were the last ones at the pits just chatting. Everyone else cleared out. lol. He ran a 10.92 for his best i believe. Great car, super nice guy.

[DOOM]

Good runs guys.
Sounds like he'll was unleashed.

[Glenn]

FM:
You had a great day running a 12.70 - congrats. :banana2:
You are right on - a TC and control arms will definitely get you in to the high 11s. Note - the control arms require hard bushings to really improve your launches. Soft OEM bushings will not do much for your launches and defeat the purpose of going to stronger CAs.

Comin to SSHS9 - l'll save a place for you in the left lane.

What do youthink of the new Sparta CA's? May order a set next weekend.

[SMOKE]

Thanks for an awesome day and a chance to uncork the FM yesterday! I am STILL kicking myself for the TC/OD thing...damn! .075 light and EVERYTHING!

My first (and fastest) run was at 11:33 AM against some blazing orange 10 second car. 14.559@95.81 with rookie RT and 60' times....car got slower and the track got gooeyer as the day wore on.

I had everyone's advise in my head. Launched everywhere from 1100 RPMs to a big, fat waste of time launch ~2K. Wheel spin and a smudgy track, but still SOOOO fun.

Thanks again to the three Pauls...

Probably got sucked into his vortex. The drafting affect. Glad to see we've hooked another one.

[Glenn]

FM:

The new CAs look fine, but most of the improved handling and launching ability is in the harden bushings. If the bushings are OEM soft you will not see that much of an improvement. But, the harden bushings will tighten up your ride.

As always, it depends on what you want. If you want to pull good launches you need the hard bushings. But, no MM can pull a 1.57 sec 60' - right! They can with strong CAs and Watts Linkage with hard bushings and the right DRs with a good launch technique.

His name is John Roberts and he breaks stuff...lots of stuff...I powder coated those rims for him,beginning of summer.He's not afraid to push that car to its limits.

[SMOKE]

Nice guy, and yes...he can break stuff, and no...he ain't afraid of the outer limits.

VERY conversational...sort of fella you feel instantly familiar with...

Hell, he even had a spare set of MT's mounted up he was willing to throw on my car for a few runs?!

[mpearce]

I put on the tubular control arms that utilize the stock bushings. I love to drag race, but I'm not all that comfortable with making my ride even harder than it already is. So I left the Metco's alone.

I went from a 1.74 60'ft to a 1.68 60'ft with the addition of control arms that reuse the stock bushings. I do not have a watts linkage either.

FM...if you're going to shave those .7 tenths...thats a HUGE seven tenths to shave. Much harder to do that than to go from a 13.7 to a 13.0. You'll need a 3500 torque converter, control arms, and drag radials to do that IMO. Good luck, and awesome runs!

Got the drag radials. 3500 is in the works, and so are the control arms and watts.

Watts link is pretty expensive. I'd save the $$$ and just do the converter and ca's first. Then if you're not exactly where you want to be...then try the watts link. Personally, I don't think it's absolutely necessary.
