650WHP on E85 and Meth!!! at 36lbs of Boost
This may sound strange to some people, but something appears holding this car back - and it isn't the tune.
Look at the torque curve with respect to rpm. Would anyone care to take a guess at what's needed to get another 50-60hp out of it?

Remember that E85 is heavily subsidized so the cost is very low right now. Hope that production will be so much cheaper that it will be competitive price-wise with Race Gas once the gov't stops paying farmers to make that stuff.
This powerband from 6-9K looks delicious! Congrats!

Our clutch started slipping on the dyno so that could be some of it.
If one looks at the specs for those cams:
http://www.briancrower.com/makes/mit...g63_evo8.shtml
There are two things that immediately come to attention. The first is the fact that these cams only give 218/216 deg of duration at 0.050", which is not ideally suited for high rpm power. Likewise, I see "106" indicated, which probably refers to LC (for both). This would be akin to setting HKS cams at +2/+2, and would explain why the torque peak occurs at a relatively tepid 6k rpm and tapers sharply thereafter.
If you have cam gears, setting them to something like -4/-4 would be immediately helpful. If not, just know that porting the heads AND installing a different cam set will deliver at least a 10% increase in power (and that is a conservative estimate) as sure as death and taxes. If you want to know how to get 700+whp, that's the ticket.
And oh yeah, invest in a good clutch. You'll need it!

I could order Bushurs new set of cams ..TedB thanks for the insight this whole process is a learning experiance
IF that "106" refers to lobe centerlines, then cam gears should help immediately.
However, if you don't presently have cam gears, I would just consider saving my funds for a set of more appropriate cams AND a ported head.
