Flat top pistons, 56cc 190 11r heads. Custom cam with .571 lift, carbed car running a FMS RPM Performer intake with a little work, QF 650 MS, 1 5/8 shorty headers , 2.5 OR H-pipe, Dynomax out the back . Dual friction clutch, through a A5 and 3.55 gears. 4 and a half months and an upgrade to an A5 later. Finally made it to the Dyno. Of course it's a "heartbreak" dyno. 349.5 hp at 5700rpm, where it was starting to flatten out. 84* and 85% humidity, also not great for #'s. So I'm not unhappy at all. The torque curve is incredible for an out of the box carb and 34* of timing, I felt. Guys at the shop were shocked out of a such stock appearing setup.
This Dyno is supposed to be around 15% lower than a Dynojet. There was a bunch of pissed people there. A GT40p headed 90 GT went before me, 306, Trick flow intake, stage 2 cam, put down 225 and 250tq. Guy after me in a 2015 gt ,intake and exhaust with tune, put down 356, he was looking for 400. Another 2015 GT, stock with a catback system, put down 340...they're showing 380 on a dynojet.
If someone could run some #'s on what a calculator says it should make I'd be interested. Can supply whatever specs needed.
