So, on a whim, I decided to dyno the Cobra tonight at XX tuning.
Wanted to push pump gas as far as I could with the car, though I think she had a bit more, I didn't want to push the stock block too hard. All in all the numbers on pump exceeded my best ever numbers on race gas last year, which is to be expected with DFI.
Best pull on pump gas was 513rwhp/527rwtq with pretty conservative timing, and a nice 11.2-11.5 A/F ratio. I guess we coulda pushed harder, but I just didn't feel like hurting anything this early in the game. This was at 14.5-15psi.
Then the fun begins..
We dump 5 gallons of 118 in her, and start to ease the boost up, little at a time. Each pull we do, we gain about 20-30 rwhp. The car started to smoke some, but none of us though anything of it. More boost ='s blowby and we thought it was normal. So after about 6 pulls on race gas, we made a nice 575rwhp/615rwtq @18.5psi.
Then the car started to smoke bad, just when we were about to do the 20psi pulls, which woulda been the peak boost I was planning on running. After looking over the car, we really couldn't notice anything bad. But the smoke was so bad, that I couldn't continue with the dyno pulls. We checked a plug, and it looked perfect... So we thought that maybe the oil I put in, broke down and was going past the turbo seal. Changed the oil, put some 20-50 Amsoil Race oil in it, and the smoking just got worse..
So I back the car out of the dyno to find this on the floor (thanks to Dan for the thumbs up)
and..
and best of all...
Needless to say kids, that's what happens when you blow a turbo seal. Raw oil just pukes out of the downpipe. I'm happy it's not the motor, though I wish it coulda held out until we made the peak numbers. 5 hours on the dyno tuning, and tweaking. I will make my 600+ rwhp. :angry:
Huge Huge thanks to XX Tuning for the dyno time, and to SteedaJeff and TurboDan for their guidance, without them, I woulda been lost tonight. Thanks guys..

When that seal is replaced, feel free to turn up the boost and see what the block can take now. 
..Or is it another car ?
