I wanted to start this thread about cams that have reach 11.999 or quicker on stock heads. So lets hear them...........

 

Would it be possible for this cam to barely touch 11's n/a?? stock heads. I need a cam that i can use with nitrous--and am still debating. Is there a better choice?

CC-TS-224XL Comp Cams TS224XL Camshaft 224/236 duration @ .050", .536"/.555" lift with 1.6 rockers, 114lsa. Nitrous/supercharger camshaft, designed for engines running up to 150 shot N2O, 5-12psi supercharger.

OR

Comp Cams TS233XR Camshaft 233/242 duration @ .050", .569"/.576" lift with 1.6 rockers, 114lsa. Amazing top end pull, extremely lopey idle in stock displacement engine. Nitrous use 200 shot, supercharger 8-16psi.

 

It's not really so much in the cam... most important is how the rest of the car is set up. You need to hook REAL well (without breaking anything ) and have the right combination of parts to get there. (right gears and clutch for an M6 and right gears/stall for an A4) Suspension work is also needed although I think some people got there without anything special.

Besides the cam, you will need some good tuning (prefferably dyno) and shift at the correct RPMs that would match that certain cam's powerband.

I'm sure it is possible with the bigger cam, but I can't guarantee it with the 224/236 on the 114. I think you should post in the nitrous forum and see what those guys think, but if it was MY car, I would get a custom cam.

EDIT: The smaller cam guys who touched or went deeper into 11s usually had a drag suspension setup and weight reduction.

 

I am close at 12.05@113.29 1.700 60'. I just had to pm my mod list to someone else so here is mine. The shift points are 6550rpm, cross the line in 3rd at around 5k rpm.

Edit: I have anything but a drag race suspension, except for removing the front sway bar and very minimal weight reduction.

CC306
Comp 987 Springs
Comp R lifters
Comp hardened pushrods
Comp Pro Mag 1.6 roller rockers
10 degree locks
Titanium Retainers
Stock heads
Impalla SS head gaskets
Jet Hot long tubes
Dynomax Bullet muffler
turn down before the rear end
K&N CAI
Holley 52mm TB
CSI Electric Water pump
Took out the AC, front sway bar, and back seat
1.5" lowering springs
lower control arms
LCA relocation brackets
Adjustable panhard bar
Weld in subframe connectors
Adjustable fuel pressure regulator
3.73 gears
Vigilante 2800 stall TC
Pro-Built Automatics "Limited Street" 4L60E
And finally, GOOD DYNO TUNING

I ran my times on 17" ZR1s all around with 275/40 17 Nitto drag radials out back and 285/40 17 Kumho Ecsta MX up front. I am sure with a little stickier tire out back and some skinnies up front I will be able to run a low 11.9X or high 11.8.
Hope this helps,
Nick

 

I don't remember who it was, but someone here has run in the 11s with stock heads and a relatively mild Crane cam (210/224 duration @.050). Hopefully, he'll chime in here.

Edit: do a search for a guy named Frank95z; he's the one.

 

atljar...stock heads GM 847 cam

 

I'd say CC306

I run this setup
CC306
Crane Cams 10308 Dual Valve Springs
LT4 Lifters
Comp Chromemoly Pushrods
Comp Cam 1.6 Roller Tip Rockers

compared to:

CC306
Comp 987 Springs
Comp R lifters
Comp hardened pushrods
Comp Pro Mag 1.6 roller rockers

 

there was a guy back in 02..i know...far off..but he ran a 11.xx at the gm high tech LT1 bolt on shoot out....he wasnt allowed to race but had a cam and all bolt ons..he ran 11's...his name was brian hartley

 

Frank Wanicka (sp?) ran mid 11's I believe w/ a tiny cam and stock heads. But that car was very optimized for drag racing.

Atljar is the only M6 I know of that ran 11's w/ stock heads.

Personally.. I ran the 224/236 on a 112lsa w/ stock heads. Ran a best of a 12.3@almost 114mph. Never could get my car to 60' worth a darn though. And still can't for that matter. Heh.

 

I think we all know the rest of the car has to be optimized. That's why i posted this...to see which cams have been made to hit 11's.

 

If you know, then why did you ask in the first place?
Like I already said, the cam is not the most important factor. I know of a couple of guys with 224/230s in deep 11s on stock heads if that helps any. They only make about 310 RWHP, which is an easy goal for just about any smaller cam with a decent amount of bolt ons.

As a comparison, mine is making 348 RWHP (A4) with a 233/239, but I only got it to 12.68 so far because I can't get a decent 60'. (need bigger slicks and stall, so again it's not all in the cam)

 

Yes it's not all about the cam. You are correct But in this post that is what we are discussing or did i read the title wrong??

I want to know what cams make enough power/not the suspension set-up you need. I don't need to know he run's 9psi in one tire and 10 in the other....i just want to know what cams have made it there.

 

Did you not read what he just said???? It's not about the power. It's mainly the suspenshion.

 

A long time ago, I had the LT4 Hotcam that went 11.80, untouched heads. That's with a pair of slicks, total stock suspension, maybe an airbag on the right side, but other than that nothing else.

 

You titled the thread, so you should know... Might want to chill a bit on your abrasiveness as no one likes a smartass.


The cams that make enough "power" are the ones trapping over 113mph ~ through an A4 at least.. You can have all the power in the world however, but if you can't put it down, what good is it? Ever seen a 850rwhp Supra mid 12's? I have... And it trapped at over 135mph. Just couldn't put the power down.
