Not anywhere near South Carolina, in Nor Cal, your right about the dyno, and I have the upgrade fuel system and plugs also, that could be part of the difference.

Never dynoed mine before the 475 upgrade but at the standard 15% loss at the wheels it should be around 370 rwhp.

I love how you guys are like "You only have 390hp?"

Geez, I would kill for any supercharger at all!!

stang435hp could you feel a big difference when you went to the 475 kit?

I started with the 475HP (crank kit), and it dynoed at 393RWHP, 39# injectors,stock 4" pulley.I contacted JDM and bought the 3.6 pulley,90MM MAF,CAI (Saleen uses modiied stock box enclosure (WHY???). I then dynoed my car and I pulledmid 430RWHP. I called JDM back and ordered the 3.4 puley with a GT500 duel fuel pump. I went back on the Dyno, I was pulling 445RWHP ( i was pissed about spending $1000 for the pump and new pulleyand getting a dismal 15HP). I went for the3.73's, JBA Shorty equal length headers,1 piece driveshaft and a custom Dyno tune. I was happy that I got an added2 degrees of timing (more than JDM's tune), and pulled mid 470'sRWHP/450 RWTQon thedyno.

Not trying to get off topic, I'm not S/Chgd, but I also had good results from the JBA Shorties.

I consider that 1000 dollar insurance for your fuel system to help prevent engine failure with the higher RWHP numbers. JMO though and our numbers are nearly the same (454 RWHP -whipple with 60# injectors and GT500 fuel pump) and did the exhaust look okay for you on the Cervinis kit? Do you have a pic or is it in the other post you started? thanks Jason

Thats insurance for sure, couldnt see going that small a pulley on the stock pumps. Could pully down again likely.


Im currently at 8 psi and there was a decent jump when I went with a smaller pulley. As you go higher up though you have to understand that the SOTP needs an awful lot more to wow ya. On a 100 hp car 20 ponies is a nice jump, when you are near 500 20 ponies you really cant feel. Its more of a time check thing, at least for me. When i get my slips it tells me.

I'll post some pics this afternoon when I get the car back.I currently have it back in the stereo shop (getting a custom enclosure installed). The exhaust setup turned out good but eventually I want to re-attach them to the side and not dump them out the back.[&:]
