Crate LS6 full bolt-on's, A4 = 400 rwhp ??
What would it take for a crate LS6 long block with full bolt-on's thru an A4 to see 400 rwhp?? I am wondering if I were to send the heads out to either AI or TEA would do it? I could simply change the cam, but it would then no longer be an LS6 engine. Can ot be done thru an A4??

stock ls6 is rated for 405...obviously it isnt all getting to the wheels, but you shouldnt need to do internal work like heads/cam to get it there, probably headers/free flowing exhaust and a good intake/TB combo should put it there.

I already know that a cam would put me above 400 rwhp easily, but I am interested in NOT breaking into the engine. Does anyone think AI's 226cc head porting service would give me the 20-30 extra rwhp to break the number being that I am an A4 car? Also, ths suspension consists of the following:
Bmr springs / Bilstein shocks
Bmr front / rear sway bars
Bmr lower control arms
Bmr pan hard bar
Umi torque arm
Slp sub frame connectors
Thanks...

2) To me swapping heads would be "breaking into the engine."
What is your goal, a sleeper, DD, good street manners? Here is a thread with some head only numbers, https://ls1tech.com/forums/dynamomet...only-dyno.html
Also, you can get a cam that would still sound stock yet make more power.

No longer an LS6 engine with a cam change? Oh jesus Christ. Who cares what it has for a cam in it, and who really cares that its an LS6? Its an LS6 block and heads, thats what makes it an LS6. If I put an LS6 cam in my LS1, its still an LS1. Swapping the cam is easier than the heads and will probably gain more than just the heads. Ive never heard of anyone swapping or porting the stock heads and leaving the stock cam. That pretty much defeats the purpose.

Agreed also. I have the TSP 233/239 cam with full bolt-ons minus heads (I have stock 241's) and in the Florida summer heat my car put down 374hp through a 3600 stall after the tune. If your putting a stall in the car (which I would HIGHLY recommend) then a good cam and bolt-ons will make the car faster than you think.

Other than that I think about 385 ish maybe 395 with a fast is the limit for a bolt on ls6 through an auto on a good day. Bolt on z06s will go over 400 but an auto is another story. If the op wants 400 he should go for a mild cam. Even one that can barely be heard will take him over his goal

Just like you, I didn't want to open up my crate LS6 longblock. I wanted to try to get to 400 RWHP with all the bolt-ons. I got there, but I am an M6. However, When I dynoed today, I was on my new HEAVY 18" C6 replica rims and I just put a a new Monster Stage II clutch in and I did NOT opt for the lighter flywheel and I now know the flywheel with the Stage II is actually heavier than the stock flywheel. Oh, and it was in almost 90 degree heat today too.
I was at 385 RHWP before the FAST 92mm. My intake is also NOT ported. You just MIGHT get to 400 RWHP on your A4 if you go with a ported FAST 92.
Oh, and I resurrected this old thread too to see if that'll help you out:
