took out a degree of timing to allow for lower octane since I have to go back out to Kansas and they only have 91 Oct. and made some adjustments for the boostmaster pipe.

Hopefully I'll get to the track this weekend and be able to test it out.

I'm curious as to why your torque didn't rise. I take it now occurs higher in the RPM band? Great numbers either way!

Stock heads? Congrats on the numbers.

not sure why the torque didn't rise. Chris even said with the new crank pulley the torque shold go up. Hopefully I didn't screw my engine up to bad out in Kansas
the torque peaked about 5200 RPM


The heads are GT-40X.
