cheers Jedi .

The dyno showed up some things i can work on to improve but my peak number is about it with this turbo i think .

Yeah, you could probably smooth a few things out but peak is pretty amazing for that little snail.
Have you installed Water / Meth? Obviously don't tune for it but as a fail-safe.

I think we've seen 300 broken at least once before. I'd love to see what the exhaust pressure is before the turbo vs the intake pressure and I'd also love to see the intake temps. I'll bet they are both pretty scary!

I seem to remember a couple people north of 300, but I also have an amazingly poor memory. Maybe they were running greddy's with replacement turboes.

No meth at this stage .
at cruise I see about 10-12 deg C above ambient and on full boost that goes up another couple of degrees . Not too bad seeing as we don't see much over 26deg C (80 f ) here .... At this stage i certainly don't need it for the street - track could be different though .

I do measure IAT and it is pretty good see above . This is with the upgraded turbo and i have it spooled up to around 12.5psi to get the 8.5psi in the UIM later in the rev range . So it is only just out of it's efficiency curve at 310ish g/s .
I have no idea on what is happening with exhaust pressure other than to say it is enough to open the wastegate by itself ......

BTW if you saw 300 broken i doubt it has been reported on this website because it would have been noticed

Nice job Brettus. Congratulations on a job well done.

Chickenwafer broke 309 with the MM/BHR turbo upgrade and 9 psi of boost. Gives you something to shot for.
