A little quicker

[MMBLUE]

Decided to go to the local dragway and see if my time had improved. Last year with K+N drop in SCT can tune, ran 14.6's or so. Today with the same SCT can tune JLT CAI and BBK LTH - CATS, ran a best time of 14.32 @ 97.28 MPH. I've got some things I'll be changing and adding over the summer just to see what the real life gains are. They include: Zack tune, cam swap, U/D pullies and maybe 4.10's. Although, I think if I go with the stock size tire, i'll gain a bit. Currently running 255's

I've got to believe that the guys running in the Mid to high 13's have a few different Mods. After the BBK's etc, I thought I would've gain a bit more. Maybe it was just to darn HOT out.

[musclemerc]

All in all, not bad David you dropped 3-10s of your ETs. What I would do is complete your list of future mods then take it in for a full dyno tune to take advantage of all the goodies and you should be in the high 13s.

Cams, pullys, 4:10s, and the right tire you're there ....:burnout:

Seriously? Cams? 20hp gain for $1200 or more if you have someone install them. Better off with long tube headers.

[musclemerc]

Errr.... He has LT's.... I installed them....

[crouse]

Do you see much HP gain with cams? Seems like a lot of money for not much gain. Although some guys just love the lopey sound of a big cam.

You can pick up 20 hp/ft lbs with cobra intake cams and they cost well under $200. Some well spec'd intake cams (using stock exh cams) will get you around 35rwhp.

Whos paying 1200.00 for a set of cams installed? Not me... I turn my own wrenches :cool:

You can go out and search the topic, gather all the info you can but I can assure you the cam swaps arent being done for just a lopey idle. Factory cams will not be that wild, maybe your thinking about high end Comp cams that can cost $1200.00. Personally i'm going with a 96~98 OEM Cobra intake cams they will give you 20HP~23HP bolt in and go, 30HP~40HP if they are degreed and advanced 4*

Advancing 4 degrees from the stock intake LC will put the cams at 110. I recommend no less than 108 for an n/a car and for a marauder that rarely sees over 6k I'd put them at 106. Advancing the cams will only increase hp 3-10 degrees depending on how far they were "off" to beign with. However, the gains before peak power occurs are just plain stupid.

Longer duration cams will have greater gains when degreed and or advanced.

Stupid as in awesome then I concur. I still need to post my dynosheets from after the install. Considerable more area under the curve!

[musclemerc]

I need to update your info on the N/A HP list

I have been waiting for this :popcorn::popcorn: Kmastl, I was wondering if you had the before and after gains etc. There are quite a few of us waiting for your results from the cams after your car visit to you know who's garage.

Are these new or used cams for $200.

FYI its very hard to wear down the cam lobes on our 4V engines. Ive seen cams removed from 100,000mi~200,000mi engines and they had no issues

I have -0- problems installing used cams in these engines

[ctrlraven]

I did a 13.72 with a Zack tune, JLT intake, 2nd set of cats removed, 3500 stall and 255/50-16 drag radials with 3.55 gears.

You'll get more performance out of a stall converter especially if you go with 4.10 gears than with cams.

$200 is a bit high for cobra cams, the 96-98s go for $175 and the 99 and 01s around $150. Not bad for 20rwhp, probably the best bang for the buck mod available.


Used.:banana2::banana2:
Used and in perfect conditon just like the ones in your car now. Like preciously stated, these cams don't wear out.

Many Mach 1s have had the cobra cams installed and the gains are a very consistent 20rwhp and when advanced the tq gains are huge.

Not bad. I was looking at the time slips page and saw all the N/A's in and around 13's and was wondering what maods they had. Personally, I wouldn't get a stall converter b/c it's my DD and I do a lot of hiway driving.

A stall converter won't hurt hwy MPG at all.

Correct, the only difference is getting going from a stop. If you mash the gas or get on it good its going to bite and go or spin the tires. If you take off easy it will take a little more to get going depending on what stall you have.

The stock TC has a multiply rating of 1.92 I believe and PI converters have a rating of 2.35. If your car is a DD I'd say maybe 2800-3000 with 4.10 gears, if you plan on being at the track a lot then maybe 3200-3500.

[MMBLUE]

Good info, I actually made 4 runs each was a different technique to hopefully get different responses. Needless to say, my best run was my first. All I did was, go around the bleach pit, back up, stop, mash the gas and spin the tires a bit get up to the line, stage, gently touching the brake with the left foot, and mash the SOB and go.

I tried going through the bleach, no tire warm up, power braking the take off and the best was the first.

I'm losing some time with second gear tire spin. Was going to try to lower air pressure down to 25 or so for more grip, but next time.

[musclemerc]

You gotta get rid of those damn SUV tires there not designed for that kind of traction

Dirt track maybe? LOL!!

YADA YADA YADA, Can't you see I'm working on wearing them down. Maybe I should let Dom get a hold of them:shake:

[kmastl]

I do have a dyno sheet from before the cams and one from after... But I don't think its a good comparison because I had my tranny rebuilt rearend rebuilt with 4.10's and also both heads redone.

Also done on different dyno's on completely different types of days.

Tq stayed the same and hp went from 294 to 302.

I wish I could have been the test dummy but it's not a good comparison with all the different variables. But I can tell you for sure that mid-range power picked up significantly.

8 HP gain. I'm curious if it's RWHP or overall HP? and what are some of your other Mods?

[kmastl]

mods include
sw lth
steeda pulleys
kn intake
j mod
410s

It did pick up significant mid range power. I do not think the 8hp gain is an accurate number considering all the variables.

If someone wanted to do the timing on my engine for free (like they do for all their friends) then we could have some good numbers for the gains with proper timing..

Thanks, I don't mind if you highjack the thread by posting up the dyno sheet.

I will look for them and try to post them later today. Might be early next week since I am out of town and the papers might be at home.

The heat and humidity makes a world of difference on a NA car. I run low 14's in hot weather and in the 50-60* temps, Im running consistant 13's with a basically stock exhaust.
These cobra cam swaps have seriously peaked my interest. ;)

Yeah, Travis and I have been talking about it. He'll be doing his soon. He's already done the P+P intake. I think next for him is the cams. For me, I'll be getting them done prolly towards the end of summer. Going to let it cool off a bit. HOT AS HECK. As far as the temp change and difference in times, I got a "Z" V2 tune and was wanting to compare with the SCT can tune for time differences.

[Bradley G]

For the longest time here , most everyone who went this route, claimed the gains were very minimal*not cost effective.
Now it seems with some of the numbers (gains) that are popping up, and parts can be had on the cheap, as long as the wrenching can be done by ones' self, (on the cheap) sounds like a no brainer.

[Blackened300a]

He's already done the P+P intake.

I rememeber him talking about this. I picked up a lower intake to send out somewhere and see if the P+P works better then my short runner intake.

Any info on his gains and how it worked for him?

[ctrlraven]

I see you are trying to catch up to me Paul. lol

[Blackened300a]

I see you are trying to catch up to me Paul. lol

Work has been good lately so I have some cash to throw around. ;)
Plus you'll have a chance to purchase a Spaz intake. :D

Not that I know of. I'll ask though. He's waiting for the cam swap until dyno.

What's your shift point?

[Blackened300a]

What's your shift point?

Around 6300 RPMs I believe.
