that hp number sounds high? 140 hp gain from where you are now? my 03 has TB,cai,hi flow cats, flow masters. 2.80 pulley Lt headers and a tune and made 456rwhp. A ported intake and you are gonna make 409 rwhp + (140fwhp-20%)=112rwhp = 521rwhp. That means a 65 rwhp or 78 fwhp pick up from a ported intake. Thats a little far fetched.

The 140 HP I am estimating is at the flywheel that's why I didn't say RWHP. My estimated HP gain is based on each individual mod's HP quoted HP increase, for example:

X Pipe 15-20 HP
Diablo Tune 40 HP
Pulley 17-20 HP
Steggy Port and Plenum 60 HP

I hope this clears things up.
the ratings by a manufacture are not what they seem. If you put a pulley on with no cai or exhaust then install a cai or exhaust that is the numbers they will post. But all together it will not add up the same.
If i added up the hp quotes for the mods I have done on my 9 gt it would be a 300 hp car but its no where close. They ly to sell their products. You can look at what i am saying in rwhp or fwhp it still does not add up. If I did porting on my 03 I would not see the extra power they claim.
