Well its time to make a few more passes. First off for those that haven't been tuned in this past November i freshened up my motor and installed headers with a 76mm turbo plus a larger front mount inter cooler. Went to a track rental and made 3 passes. Had some gremlins and fuel map changes to be made but pulled out the day with a 10.75 at 135mph with 22psi and conservative timing. 60 ft times where all bad. New cam makes way more torque and im lighting up the tires on the launch killing the 60 times. I also think my converter is way loose now with the added power and im seeing nothing less than 5400 rpm down the track bouncing of the rev limiter at the top of every gear. To top it off i broke my diff on my 4th pass and thats all she wrote!!! Haven't touched it until last week, made some shift point changes and reprogrammed the boost controller for less boost on the launch, also slowed the ramp rate on the boost . The mph is there to make a run into the 9s and i still have 8 more psi to throw at it. Im not going to hit it with all the boost just yet, i have to solve the late shifting problem. Plus get a feel for if the converter has to be re stalled lower. Never the less i will be there around 6.30pm if anybody cares to join me. Oh yes im driving it there this time so the rear is nice and warmed up for the beating its going to get.. I will post back some results later.
