I just got the April 2003 Vette magazine yesterday and they have a step by step photo instructions as well . The article starts at page 31 and runs till page 35..
They also have baseline dynos and after install dynos and comparisions on 0 to 60mph...Its impressive.
the acceleration goes from 4.97 seconds to 4.51..
If its real .4tenths is a worthwhile mod especially from 0 to 60mph..
The peak hp increase is 12 rwhp and max torque increase is 11 lb/ft..
Of course the benefit of cool intake air shows up on the road versus the dyno so thats probably where the excellent 4.51 vs. 4.97 showed up...
I think the installation looks a bit of pain in the butt..yet when your done I believe you will be pleased..
Good luck and if you get a chance check out
www.vetteweb.com they may have this article on line as well as in print. You might find it interesting to read the excellent report on the product your installing.
