A Few MPI Turbo Questions: Heat / Intercooler / PCV-PTI

[jeffgilbert]

Read Allen's post above he built it for me and there is a lot of upgrades to it the billet wheel being the biggest improvement in the turbo. The evo flash has 1 season on it now and about a 1000 miles I really like it. I can over rev a bit when the switch is on 10.5 #'s of boost and not bang off the limiter and I am running race fuel at that setting but am not worried about detonation because of the timing pull.


And you are correct when we pused the 14 to 13 #'s the ratio hp/ #'s of boost dropped off as we got close to its max output. I am still waiting on MR. ULMER to finish the 14 for racing and we arte trying to push that one to the neighborhood of 20#'s on a CAT turbo or whatever he ends up sticking in the thing!!!!

What is the advantage of the billet wheel? Do it make more boost or quicker spooling?

Well it is better balanced, more efficient less drag and quicker spooling also am running the Ulmer header which I believe makes a big diff. It is capable of much higher boost levels than the stock MPI wheel so I believe the efficiency range is wider that is why the old 14 ratio dropped as we pushed it to higher #'s - ah maybe?

I have a ulmer header as well do you think the wheel would provide good results on low stock boost or more so when you get in the higher number.

well I would call Allen to find out the particulars when he took my sleds and started on them he said you need this and I said yes I do!!!!!!!!!!!
