awesome figures mate
as for the pulley, i've been thinkin bout it and can't see how they'd use different pulleys for each model when if you order other underdrive pulleys you just order an sr20 pulley, not specific. my g-spec one uses a spacer and is still very close to the crank casing, without the spacer it would foul real bad.
Id be putting an UR pulley on it to be safe tbh. 140ft/lbs is the standard torque figure?
I think he's probably openend up the top end HP a bit though at higher revs, maintaining 140ftlbs upto around 7500rpm by the sounds of it.
did you try that MAF in the end?
