spork Posted March 13, 2005 Share Posted March 13, 2005 Good and bad news. I made it to the dyno, nothing broke and I made it back. Bad news is that I wasn't able to build more than 19psi of boost on the dyno. We figured out the problem and I'll correct it tonight. I didn't have the neccissary pieces to do it on site. So you're probably wondering what kind of power I made...right? Well, 346hp and 353ftlbs of torque. I roughly have another 9-10psi of boost to add to it, and I was roughly making 12hp per additional pound of boost. I figure I should have no problem getting to 425-450 with full boost. Overall, I'm fairly pleased on how things turned out, even if I'm not getting full boost. As you'll notice by the chart, I'm getting boost fairly late, it's not near that bad when going from one gear to another as the turbo is already spooled. Also, I have a cam change planned to help extend the rpm band as my current springs start giving me float much past 6300 so I'll swap a set in as well at the same time as the cam. Here's the dyno chart Quote Link to comment Share on other sites More sharing options...

Sparks280zt Posted March 13, 2005 Share Posted March 13, 2005 James what engine and turbo set up are you running? Quote Link to comment Share on other sites More sharing options...
spork Posted March 13, 2005 Author Share Posted March 13, 2005 Its a l28et with forged pistons with compression bumped to 7.8:1. Stock p90 head and cam with casting flange cleaned up and gasket matched. Custom turbo header (made by me) and one of Thagards intakes. The turbo is a master power T-70. I have a whole list of other mods, but those are really the big ones. If you want more info, let me know and I'll list it later...I just got a reall big headache. Anyways...stock rods and crank tho.
