380hp/330ishtq. 27.5psi.
Limiting factors:
85* weather
2" hotside piping
92 octane
VICS manifold
2.5" preturbo intake piping.
Timing map of retard. 7* at peak power
And log. 291kpa
This was a glory pull. Quite questionable on the street/track. Too much boost, not enough timing. But up to about 20psi it was making solid power.
15psi is ~300hp. Great on the street.
20psi is ~330hp+. Great for mexico runs.

They get knocked into the seat by all the det.
In reality I ran single digit timing, and still made power somehow. Its not a "safe" tune. I need e85 for that.
More of a "what can we do thing"
In the winter I'm going to go back with e85 and see what happens when its colder outside.

Me too. I'll fab up a 2.5" hotside pipe, and a 3" inlet pipe before I go.
Its really tight on space though. The compressor housing has to be clocked in just the right way, which leaves not much room between the compressor outlet and the subframe. I may try and trim the shelf if I have the turbo out anytime soon.

Of course, Aidan could turn it up to 35-40 psi...
