Cherry on top?
I currently have a 99 a4 vert with an A and A procharger @ 7 pounds, L.G. longtube headers, and L.P.E. fuel pump. I would like some input as to what other mods I could do on the stock bottom end that would yield me the best results in the 1/4 mile? Is it worth the money to purchase an ls6 intake, M.A.F. or bigger throttle body? Thanks for all replies.

Stock tranny. What are ideal gears? I had a mechanic tell me that the ls1 runs better at 2500 to 3000 r.p.m. versus 1500 to 2000 r.p.m. anyway. What gears do they suggest to use with a supercharger? I dont want to be cruising at 65 with the tach above 3000 r.p.m. if possible.
Thanks for your time.

You have invested in a power adder - use it. Install a smaller blower pulley if you want to make more power.
Yes, I do think an LS6 intake would be worthwhile, but I'd still pulley it down and retune. Skip the MAF and TB junk.
Also, if you haven't already done so, make sure you have a good PCV setup to prevent blowby. A PCV catch can and a valve cover breather are a good start.
Cheers,

I think you would be pushing the limits of the stock bottom end with more boost. You could put tires, a higher stall, 3:42 gears, hardend output shaft, maybe more boost with meth. heads, cam

A stock short block can handle 700+ rwhp if the proper fuel and tune are used.

true it is all about the tune. I know there is a member that has 700 hp on his stock block. I ran 7# on mine never had a problem but I hear most stockers are time bombs around 600 crank hp.

I'm not against forged motors, don't get me wrong. I ended up preemptively installing one, but my point is that if you are willing to live on the edge you can make huge power with a stock motor.

I agree with you on RPM. I have one of their 4L60's waiting to go in within the next week or so.

A converter and some trans work will be huge gains for you.
I would not push the stock bottome end much further than you are, but an LS6 intake is a good idea if you can get one at a decent price. For you the biggest gains are not going to come from making 10-20 more HP, but effectively putting what you are making to the ground.

blown z06; quick question, I was told that a fast intake wouldnt really do any good, the reason I was told this is because, the blower is already forcing air into the car, the heads do not match the intake ports and cam?
Is this true, this is what has kept me from buying one. thanks

I can tell you that in my opinion it is not necessary. You can make well over 750 to wheels without a FAST intake. If you are successfully putting that down.. then maybe it will buy you something. Anything beyond that would be speculation on my part.

I bought the car used and I assumed 2.73s is what I had until they had it on the hoist and found out it had 3.15s (at least that is what was typed on the sticker). What kind of money am I looking at for upgrading my transmission and do you know anyone locally around the west Chicago area that can install? What kind of cam would you suggest?
