Hey guys, just another cam question but I am sort of confused on what I should choose. I have been reading a lot and there is SOO much information and it all is getting confusing.

Here is my dilemma, I am looking to get my 99 t/a a4 into the 11s before july and I know a cam could do that. I do not want a big cam. Currently my car is running 12.8s 12.9s and I'll list the mods below:

Engine:
LS6 intake
Ported & Polished TB
TD's
LT's with 2.5 cutouts after the collectors
AIR/EGR/O2 deletes
Custom CAI
NGK TR55 plugs
*Car has never had a tune*

Suspension:
BMR adjustable TQarm
BMR tubular control arms
BMR adj. Panhard
Eibach Prokit LS1 springs in the Front, LT1 in the Rear

Rearend:
Stock 3.23

Transmission:
Built 4l60e - *but skeptical about tranny mods since Ive burnt 3 up in year, thats why I don't want to upgrade my TC till the tranny proves it can live at the track and be daily driven for awhile
24k Cooler mounted Dope
Poly Trans Mount

More to list, just ask because I cant remember everything

Anyways, I dont want a big cam. I like the sleeper idle. I have a set of 799 heads ill put on during the cam swap. They have 2.02 intake, 1.60 exh Manley stainless valves with the exhaust ports polished. Heads have also been milled .030 I believe.

So what cam would be tolerable with a good tune with a stock converter? Reason I'm not going all out on the engine is because I have a LQ4 block going into it in the future. I just want to beat my friend this year. Will a TSP220/220 or something similar be good enough to get me there? Is it friendly with a stock stall? Id hate to do a heads cam swap and only hit 12.00's haha. Will those 799 heads be worth it? They look really nice and came off an 11 sec. car...

Any other mods (other than a Stall... yet) should I do?

That's a tall order, better of spraying the car to get in the 11s

Even with a 220 and gears I don't think you'd get too close unless you did some serious weight reduction....

.8 tenths for a small to medium cam??? No way, wont ever happen. You are under-estimating how far you are from 11s. That being said, wanna know HOW to get to the 11s? 3600 converter with sticky tires will get you damn close, H/C may or may not depending but you should eek in there with that and a stock stall, or a 100 shot of the juice and it should be in the bag. You put on a 100 shot, go run 11.8s and some poor guy that has a good cam and good stall can run 11.6s with no juice......My .02.

Put a 4000 stall in it and run 11s.

can that cam go 11s on stock stall yes my car went 12.0@113 i think mph might be off but i know it went 12.0 2x.just with boltons and 3.73 racewieght around 3350

maybe consider a EPS cam or a ls truck torque cam from comp,54-455-11.

Get a 3600 stall and a cam and you will be in 11's

Running 12.8 - 12.9, you are going to need about a 100 hp increase. I am not a fan of nitrous or forced induction. So, that leaves displacement.

What I am suggesting is either sleeving and stroking your LS1 or installing an LQ4 based motor or an LS3-based motor . . . 402 / 417 cubes should do it !

With the extra torque, they would be able to "pull" your stock converter . . . For "Dead Smooth" sleeper idle, take a look at the Lingenfelter GT-11 cam.

You better start saving for a 12-Bolt / 9" Ford / Dana S60 rearend, too, as you will break your 10-Bolt in a short time with that much power !

how the hell do rebuilt 4l60e's go out so damn fast.

ez2cdave

Usually by people telling customers a bunch of lies and using inferior parts, instead of the best replacement parts.

I suggest getting your trans built from RPM or FLT. They will hold, then do a 3800-4000 converter.

Yes what this guy said^^^^^. Or get a book and start studieing how to rebuild them yourself so you don't get fu**** with tranny guys putting cheap parts in and pocketing all the money

z99ls1

iTrader: (12)

I hope it would be that and not just because they suck rebuilt. I plan on rebuilding mine myself until I can get it to hold good power. That is if and when it ever goes out.

I am getting ready to sell off my head cam ls6 top end that will do it with tsp cam

n.m.racer

yea sticky tires in what i need. Im running that 12.8 on street radials. figure i can cut my 60' with some 15s in the rear with slicks maybe pick off a tenth or 2. Im not a nitrous guy but i see what your saying and since ive never played with nitrous im kinda nervous just to jump right in.

Yea 100 horse would do it but with those heads I have (without flow data) is kinda hard to get a cam to match it. Is something around a 228 too much for the stock stall?

I have a 9 inch housing and when the 10 bolt goes, im concentrating on finishing that. Since Im not launching crazy hard and not cutting 1.60 60' I should still have some life out of it. Runs smoothand doesnt whine and the posi works great.

The 4l60 isnt bad, it totally is what you all are saying, just guys either been cheating or not building it right. I supposedly burnt 2 Zpaks up... This one has made it 2000 miles more than the others, since they all went around 1200 miles. Once I hit 5-7k Ill put a SS3600 in it, just tired of dropping that tranny...

Ill definitely check out those cams you guys suggested. So lets say I get a 1.85 60' with sticky tires (currently running 1.95-2.02 easing it out of the line and that drops me to 12.6-12.7 range... (sounds tricky but I have slips proving my street radials getting a 1.90 with my 3.23s before a lot of mods) will heads and cam shave 6 to 7 tenths? I know a second sounds impossible with a small cam but what would be the best caam to do it with my head set-up that will be friendly with the stock stall? Ill go as big as friendly

Sorry if I'm so dead set on that stock stall, but I dont want to throw 800 down on a converter just to watch it possibly get trashed by the tranny lol. I know they restall but why waste it on that. Might end up just putting a 400 or 4l80 in with the engine swap so a stall might just be wasted for 6 months of fun.

You don't need a th400 or 4l80. Thats such a waste. You only need a properly built 60. Why people are so against them I have no idea. You have no stall, no cam, and street radials. You are (right now) the perfect canidate for a stock 4l60. And typically stalls cut about .6 off your 1/4, hence the reason why I said you will be brushing 11s with one, not actually in the 11s. Dont let some of these guys fill your head full of crap and then you get disappointed when you actually get to the track.

If you are running 12.8 on street tires yes I believe you could sneak in the 11's with a good cam and slicks.

I have a m6 but a guy i know didn't want a big cam and he went with a z06 cam and a 3,600 stall. with bolt ons he ran 12.2 on nittos. his car was nothing special but ran pretty good and sonded like a stock car.

Im pretty close to 11's with just a stall. I can see you dont want to break ur trann but putting a big cam and heads is gonna be about as hard on it as a stall. Let me just tell u. U will NOT gain much by putting a cam n on stock stall. I have already been down that stupid road. As soon as ur car shifts with that biy cam and stock stall it will fall on its face cuz ur shift extension will be so low and bigger cams need more rpm to make power. You wuld b lucky to gain a cuple tenths with a cam and stock stall. I put a cam n my lt1 and ran exactly the same as it did with stock stall becuse it fell on its face everytime it shifted

A a larger cam and stock stall is actually counter productive, huge waste of time and money. If you cant get out of the hole or stay in the power because of the stall lugging the motor down you won't come close to 11's.

Put a crap ton of weight out of the car with a Z06 cam is about your only way of doing 11's without a stall and getting a "bigger" cam.
