what to do to get to 400 Rear HP
Ok per these HP Calculators, Im about 379 Rear Wheel HP> What do I need to do to get to 400, Im thinking Intake manifold would help, but what else without opening the engine and messing with heads and cam.

I dont think I was that high either, but if you do those HP calculators....anyone ever match them with a dyno...
I hit 108.58 mph at the track and we figured the car weighed with me and gas around 3832. Im sure I can hit 110mph with a very good launch, which I never got Sunday.

I don't think you're that high either. I'm guessing around 350 plus or minus a few. I trap at 108 and I dyno'd 328 rwhp last Saturday (pretty strong for an A4 with only a cat-back and lid). Get it dyno'd and find out.

Actually With The Intake Ud Still Be A Littly Shy Of Where You Estmate Your Self To Be Now Id Say 360 Rwhp And A Good Cam Will Land You 390-415 Depending On Cam Choice And Luck(tunning)

get a ORYP
under drive pullys
LS6 intake
ported TB
good plugs and wires
good fuel filter and thin oil
remove A/C from car (you lose 1 belt)
get a cut-out
maybe a lightweight drivshaft
and a really good tune!
and youll see around 340-360 rwhp
if you really want 400+ you neeed H/C

I agree, you're not at 379 rwhp as your car sits. You might be closer to around 350 rwhp. To break the 400 rwhp mark, you're going to need to go internal. Add a ported throttle body, ASP pulley, plus a nice sized cam and you'll be there.

The only performance mods you have are exhaust. I would count the programming and MAF as iffy to maybe a few rwhp. There is no way you are at 379rwhp...more like 340 or so. Not trying to flame you...just benig realistic. There are quite a few cam packages that will get you over 400rwhp, but since you don't want that, you need to do ALL the bolt-on mods including EWP and maybe a lightweight driveshaft to have a shot at 400. Most HP for bolt-ons I have seen is 370ish...

Look at my mods to get an idea of what you need to hit close to 400rwhp. Although I'm still short by 1 rwhp! LOL.
Your gonna need the following......
Lid, Ported TB, Underdrive Pulley, Cam in the range of 224+ duration and last but the most important of all is a LS1 Edit tune! If your car is running without proper tuning and Air to Fuel Ratio you can't make good power.
