wow i have that same setup but with and aftercooler. sorry for asking a quetsion inyou post. but could i runn a 13lb pully with a aftercooler, on a stock motor? do u guys think that it would blow?

 

if you're already running with that AFM powerpipe, then you're already pushing about 10psi.

 

no the motor isnt stock it has the saleen heads and saleen cams which ARE different from non-pi heads i learned yesterday. im not sure how the cams are different. but the thing has underdrive pullies x-pipe borla exhaust saleen headers. CAI. s/c running 9 psi. 4.10 gears

 

no theres not a problem with that

 

I dynoed at 376 rwhp and tq. I'll scan the graph when I get back to NY. Tim from MPH is the best there is when it comes to tuning these cars. 136k miles and it runs great....ask the guy in the BMW that was riding my ***. I made him disappear quickly.

 

Hey BicketyBam
That's outstanding! What fuel pump, sparkplug and gap are you running? I'm going to get my 03 tuned Saturday. Not sure what to expect since my car is stock with auto trans, except for the Vortech.

I'm going to install new plugs tomorrow one step colder but I'm not sure yet what I'm going to make the gap. Stock gap is .054

 

I also found a more experienced tuner near me and talked to him about the 10lb pulley. He said that a 10lb probably would not make any more HP than the 8lb since he would just have to time it down in the higher rpm defeating the purpose. He said he wasn't at all worried about the higher boost with no aftercooler. He did say though that I might see a little more power at a lower RPM. Of course this remains to be seen.

 

i should be able to hit the 370s once i get tb/plenum & headers.

 

What is your set up now?

 

SVT Focus fuel pump. Check www.modularpowerhouse.com for the Mongoose kit to see what plugs they use. Not a clue in the gap.
