Go to the exhaust shop and ask. Can't help you with the power level (13.8hp?)

All of these can be done yourself. Without having to get it tuned anything further and you will. If your going to do these add the CAI to your list to. More air, More Bang, More Exhale, More power.

Yellaterra.com for the pulley and rockers

and the exhaust, just pop down to your local exhaust shop. If your up for the task its not to hard to fit it yourself so you may even be able to just source the parts yourself.

as said above these things are all worth while and a gd place to start. At 10 psi is the most boost the factory settings can handle it no worries (without tune), and that be the max boost without intercooler. You could even put a stealth Water 2 Air intercooler on without a tune no worries. But a Air 2 Air intercooler will need tune to drive.
my guess would be about 150-160 rwkw.
I wouldnt put any more boost than 10 psi without intercooler and tune

also if you going to do a few mods and do need a tune seeing you in melbourne give Scotty a call at Chip Control. He is bloody brilliant at wat he does, I reckon he is the best at it.

you can run 12psi without a tune or cooler no worrys...

at the end of the day you can spend alot of money and still not end up with huge amounts of power..

the l67 still pull hard off the line

Go speak to the guys over at www.l67torque.com • Index page

10 or even 12psi no intercooler is ok... but my WHII Statesman (daily driver) has the super 6 in it. On hot days in melbourne (like monday where it was 43) the engine gets damn hot. It goes down on power considerably and i would estimate the intake temp being well over 100 degrees. I would be careful about going to 10-12psi without an intercooler, especially if you tow or drive with a lot of weight in the car.

Extractors/Exhaust system, upgraded pully, possibly Water to Air intercooler and a tune would give it a bit of punch off the line, probably enough to out run a stock Gen3 (Depending on which car its in).

Cheers

I think it was FIT who did a little test with 8psi to 12 psi on the dyno. Same car, no intercooler and no tune.
the power in the car was its highest at 10psi. At 11 and 12psi the rwhp dropped because of the intake temp was to hi and the ecu pulled some timing out. If the intake temp is to high you also could get some detination whih aint gd. As feistl said, go to www.l67torque.com • Index page and have a read. There are some wikard L67 cars on there with very gd hp and some very quick ones aswell.
And with these engines you dont need that huge hp to win races as they create the power so quickly and easily.
