Plenum- Combined with TB, exhaust, and custom software tuning- 10-15hp depending on model with more improvement on the 3.2L.
Airbox- 987 box performed the best gaining 1-2hp on 3.2L

I'll put this here instead of a new thread as it is somewhat applicable. Care to comment on my plans on a 2.5 base? I'm thinking maybe +10 whp?
- Underdrive pully - check.
- Lightened flywheel/clutch? - In a nutshell, Raby said the 2.5 could handle this the best. Is there such a thing as a lightened dual mass flywheel?
- Weight loss- -367 lbs. (2,455) so far. Goal around 2,350, including weight added back on (structural stiffening and body work/aero).
- TB, software?, exhaust (headers, 2 cats, no mufflers (for weight loss) - still need the headers. Will I need 2.5 specific headers? Would Pedro's system work adequately with the semi-custom software? Alternatives; rolling dyno plus? I'm looking for a broad range torque improvement, not 6700 rpm hp. This is more of an auto-x/street car than track - built for fun and don't care about being class competitive.
- Manual steering.
- Re-working of body/drag but I'll leave this alone for now but it will reduce the hp required to go x mph.
