e_kobz's FP 71HTA stock block/head/cam Evo IX - 450/400 on E85 @ 31psi
#21
It comes on a little different than the stock turbo. On the stock turbo I was hitting 30psi by 3500rpm. Today we were hitting 34psi by 3900rpm but we were getting insane surge. So we made the boost come on a little slower to keep it from surging. With a anti-surge housing I should be able to get the boost to come on faster like it did before. But for now I'm happy with it. And from what it seems the manifold didn't hurt spool at all. Like I said before the 71HTA just wanted to spool.

Here a couple things I encountered with my car with fuel issues.
A unmodified 255 on stock wiring was out of fuel at 430whp dynojet 23-24psi on a Red/e85
A 450 pump on stock wiring was out of fuel at 500whp dynojet 28-29psi on a Red/e85/ID1300
I'm not sure how your dyno compares to a dynojet.
I'm going to run a Boost a pump and see where that takes me. If its not enough then a rewire will come into play.
Your recent boost graph looks a little safer below 4000rpm where the stock rod bolts tend to break. Do you have plans to build an engine?
