Doubtful now. Transmission cooler didn't work out where he put it so it's getting pretty hot. I think he wants to move it before driving it out there.

He ended up having an older, thinner trans cooler laying around that we were able to get sandwiched in between the fans and the intercooler. Seems to be working much better there.

Well the converter flashes up over 4500 RPM and there is full ( only 4#) immediately. It starts whistling out the BOV in the 2300-2500 RPM range just cruising around.

Track outing was a bust. Only made one pass and he had ignition issues. We didn't have anything with us to check it out, the track was too crowded, and the rubber was peeling up because of all the rain from all last week. He pulled the plugs this morning and found one with a burnt strap. Not sure if that happened during initial tuning or if there is a problem with the injector in that hole. We have to keep an eye on that.

Symptoms are all indicative of a broken ring land.

Boner has REALLY BAD LUCK. I thought that there may have already been something wrong with the motor even before the build. It had more blow by than I would have liked. We wont be taking it apart for a another week or so to find out exactly what happened. We have to put LS2Formula's car back together.

Damn. Sorry to hear about your bad luck. Really was curious to see what these Master Power turbos did setup like this...

The LS3 is almost back together. It's getting a stock stroke crank and low compression pistons so the cubes will be around 380-382ci. We are looking for 9.5:1 compression.

Joe just ordered one of the new Holley HP EFI systems. The uncertainty surrounding that other computer was too great for him to bear. I started this writeup on the Holley standalone system for LS2Formula's car but since Joe is getting one also, I figured I'd tie it all together.

Mellow at 900 RPM or so. I thought there was an idle video. It will be even more tame when it comes back out. 2-3 weeks.
