Some of you may have noticed that we've been struggling with the trannies in our race cars since last fall. The short version of the story is that we made some major internal changes to the fluid flow in these two trannies, and we just weren't able to find our mistake without outside help. Turns out that we had an internal air sucking issue that was reducing our line pressure and causing us to melt third gear - over and over and over again. Once GM Racing stepped in, and ran my tranny on their tranny dyno, they were able to give us some guidance and all the previous issues are now in the past.
Since implementing the fixes, Bob and I have both run our cars at a couple different tracks each and made quite a few successful passes without any more melted tranny components. In the last month, we've raced at National Trail Raceway, Milan Dragway and Summit Racing Equipment Motorsports Park (previously called Norwalk Raceway Park).
There's no doubt that we're making plenty of horsepower. In fact, both of our FWD race cars have already exceeded 150 MPH this summer. We just need some more work in the first two quarter mile intervals (0 to 60 feet and 60 to 330 feet). 330' to 1,320' feels REAL strong now.
Here's my best timeslip from last weekend in the white car. Check out the 31 MPH gain in the back half...
Our immediate plans are to add a boost controller and do another dyno tune. I think it's been two years since we dyno tuned the white car, and we've learned a lot since then.
We're going to still try our best to run eights in both of our cars, in the near future, and in the summer heat.
