There was a local Dyno day here at MAP this weekend. I pulled the head off my car to replace some bent exhaust valves and drove it down there to see how the car did on an AWD DynoJet.
I replaced the 2mm oversized exhaust valves with 1mm over valves. I ended up lapping them in, which worked great and they sealed just fine.
We turned the boost down to 36psi and did some street runs on the way down there, everything looked good, if felt good on power for that boost level. We looked at the logs and made some changes, upped the boost to 40psi and the first run it miss fired a little and made just under 800AWHP at 40psi. So we added some timing where it was missing and the 2nd run was clean, 829AWHP and 554ft/lb at 40psi with a little less overall timing then it had when it was on the dyno early this year at DB Performance.
So we cooled the intercooler down and tried to up the boost again, shooting for 44psi, forgot to up the boost cut, fixed that and tried again, it missed a lot, and put down 860something.
At DB early this year at 40psi on the dyno dynamics it made 720 un corrected AWHP, and at the same boost level on the AWD Dyno Jet it made 829ahwp at the same boost, dang.
I figure a clean cooled down pull at 44psi the car would make low to mid 900's, which is right were it should be.
I should have pics and videos later this week, thanks Josh for helping tune and use your camera.
A big thanks to all the people that made this car possible: Ryan, Kyle, Josh, CP Pistons, Carrillo rods, Karl Ramm, KRAMM-LOX, Paul, Chuck at HTM, Shane at DB Performance, Jacks Trans.
