Best CAI-Exhuast Combo for max RWHP?
 

I didn't want to hijack the 500RWHP thread.


For now my plans are exhaust the ARH Long tube system, maybe adding a back half, but if the back half flows fine with the ARH header cat/back system I may leave it.

Vararam intake when it shows.

3.90 or 4.10 gears when they show.

Hurst aftermarket 40% shifter when it shows.

I don't want to mess with the PCM for now, and don't want to toy with the engine for a while.


Hoping for 400-420 RWHP, but dynod at 359 RWHP and think that CAI and exhaust grabbing 41+ RWHP might be a little pie in the sky untuned.

My thinking may be wrong but I don't see the CAI+exhaust add's to be a highly cumulative effect on RWHP.

You can make 41 rwhp with intake, headers, high flow cats and a tune.

But you need a tune with long tube headers.

I figured, I am reluctant to have the PCM messed with but figure I will end up caving as I plan to go with the ARH long tube system.

I would put on the ARH system...then an axle-back for sound...then either the New Era intake, or the Roto-Fab depending on you taste....Then I would do a laptop based tune so you can switch back and forth from stock for warranty reasons.

I would expect 50RWHP from those Mods.

I would be happy to help with pricing and ordering if you decide to.

would you mind explaining a laptop based tune? I wrench but its all on old school stuff, (no PCM's)

Basically it is a wire that plugs in from your laptop to your car...then with a special program you gain download a new PCM tune into your car! When you want to change it you just plug back in and download the stock tune back in. There will be a lot of tunes available, such as:
stock
CAI
CAI + Long Tubes, etc...

and you will be able to switch back and forth, or upgrade when you change the car or mods in the future. Very easy to use.

^^^ How cool is that!:clap:

I have Ls3 6sm, corsa exhaust,ARH, and Tune didn't get but 405 rwhp

who did the tune for you and you need a CAI of some kind.

Correct me if I am wrong, but the PCM tune runs around $600.

600 would be at the high end of the ball park...But remember this tuning setup will allow you to change many times, as well as do a custom tune.
