Dyno Tune was today....
well i went down to ralph at ground zero today to get my car dyno tuned. It was going great until we discovered that i have a leak somewhere. i'm losing major boost. we couldn't get past about 11 maybe 12psi. so basically now i have to take my turbo off inspect everything, and replace the intake manifold gaskests...
However, there is good news.
At about 11.5 - 12psi i made 295rwhp @ 7500 on a mustang dyno. People say to add about 8% to mustang dyno numbers....but i dunno. Once i fix my leak(s) i'm gonna go see what she can do...

Nice! Thanks for sharing your runs and mods. Where does your turbo spool up. A friend of mine in North Dakota has that turbo and a microtech.
Good luck finding that leak. I hope you find it soon and get more great numbers.

After reading your mods I wonder if you really have a "leak"

I also got a few PM's of a very similar, if not the same problem with the same turbo.
G Luck though, and please keep us posted if you find your "leak"

I'm pretty sure it is a leak because of the sound it makes once it gets to about 10psi. The turbo spins and spools great, i have not had any problems with that. But i think my problem might be a combination of having a boost leak, possible vacuum leaks, and slightly restricted exhaust at only 2.5 in. i have no cats or anything, but its still just not as open as i'd like. I dont think it is the turbo, or at least i certainly hope not.
