Just got the car back from the tuner and I was a little disappointed in the results. I know dropping the compression didn't help me, but I'm wondering if using the Ford GT cams also hurt?

[Helomech74]

Seems I can't edit my previous post. The pulley combo was incorrect, I'm running a standard IW crank pulley and custom 3.8" head unit pulley to get the boost listed.

 

[98 Saleen Cobra]

Congrats on it being done bro!! I posted on modfords.. But that combo makes much more sense for 11.8 lol. I'm like damn that thing is eating like 10psi ahahaha. Pulley that sucker down some and throw some E85 in it

I don't have a lot or blower rpm left to play with and the pulley was custom made due to clearance issues. So, I'm going to call Procharger and see if they can offer some insight. I have a 3.55 pulley in the shop, but it would need to be machined to fit and it would overspin the blower by about 5K rpm so, I don't want to do that just yet. I was really expecting more boost, but it appears that my engine is very efficient and not restricting low very much, hahaha. On a plus note, the torque curve looks very similar to a PD blower after about 3500 rpm.

 

[Helomech74]

Keep in mind too, these numbers are on a Mustang Dyno with eddy current load turned on and car weight figured into the calculation, so they are fairly realistic street numbers.

 

[98 Saleen Cobra]

Oh gotcha that all makes sense then lol. Yea if it's loaded with the weight of the vehicle that's probably looking closer to 700rwhp.. Which is about what I would expect. Yea that engine is flowing some air that's for sure.. I know that prochargers don't like to be overspun like Vortech's do. Maybe you have that F1R laying around
