Everything was going so well yesterday, finished tuning low boost on my dyno and she was running great. She was showing very nice efficiency at high rpm, making peak power at a lofty 9500rpm and only very slightly dropping off on power out at 9800rpm.
Made 451whp/274tq @ 17-18psi off gate.
Turned it up a bit to 23psi, made 532whp/323tq.
Turned it up a bit more to 26psi, and made 589whp/353tq. Quit there, called it a night.
Excited to crank the boost, we went to go finish the high boost at a local Dynojet this morning, and everything just went wrong. Way too long of a story to tell about everything that went wrong, and I'm tired of telling it already!
We knew it was bad, and I felt like just throwing in the towel for IFO. But the guys said lets do this, we have to get her up and running for the event, regardless of the bad luck today.
Soooo..........
We got her back to the shop at 3:00pm and immediately pulled the motor, tore her down for inspection and decided what to do. End result is that we now have a damaged crank, horribly spun #4 rod bearing, all 8 exhaust valves are bent from contact with the pistons, and I can't reuse the pistons again.
After going over a few different options we've decided to rebuild the block tomorrow and try to get her back up and running in time for IFO this Sunday with what we have here at the shop that will work in a pinch: 75.5mm Vitaras, Eagle rods, and another ported Z6 head w/stock size valves.
I always joked around about building a sleeved block with Vitara pistons, and now it looks like we are actually going to do it because of todays events. It's half retarded, I know.......
