stock 317's at that


24.5lbs. I believe the dip on the big end is due to a couple of reasons:

1. WG cracking open. only have a 10# spring in it.
2. backpressure from my small a/r exh. housing. (.96)

Going to put a 15lb spring in it and see what happens. Then if nothing, I'll put a 1.08 housing on it.

Is that a t4.turbo? Did you measure back pressure? Did you dyno on any other boost level?

Badass car

Ebay IC. ambient was 93. IAT's were 126. Although at the airfield event IAT's were getting to 160.(obviously b/c running through the gears vs. just a 4th gear dyno pull) Motor is 8.5:1 and on 116oct. Still was able to run 18* with zero KR.

T6 flange. haven't measured backpressure. dont have a BP gauge. So that's why i'm going to put a 15lb spring in it. If its still table tops, i'll assume its the AR and will order a 1.08

Great numbers JP Congrats .
I bet with a set of AFR, PRC or TFS heads you can gain 60+rwhp 50+rwtq

I gained 82rwhp going from 241 heads to AFR 225 + 1psi on my little ST80 347ci
