Maybe tuesday, UPS didn't show up friday. Always the little things that hold you up. But i did go back and modify the exhaust housing and wastegate, and wrap the hot pipe. I didn't realize how small a HX-35 Compressor wheel was until now. I have always set them to the side and just bolted on a B1. I may put a HX-40 compressor wheel in later.

OPoole when you say waste gate tuning did you open it earlier or later? It looks like you have an internal wastegate on the secondary turbo only is that correct? I found on the dyno the earlier you open the waste gate the better but on the road it can be a different story.

Started with it lose, kept tighting it and the tq kept coming up!

What did you abort the last pull?

Seems like just welding it shut would produce the most torque !!!

The truck only had a 60psi. gauge, it pegged the gauge instantly i didn't want to blow his head gasket. Thats why i aborted the run . it was making real good power, i will let him take the truck back next time. to see what it will really do with a 100psi boost guage.
