BTW inlet temps shouldnt change from compression but turbine may behave differently. (Compression affects EGT). HEAT of COMPRESSED air/fuel will increase!
That said Id keep manifold inlet temps cool(close to ambient) if boosted(A/W intercooler) With compression up where you're at I'd add water injection to slow combustion rate some.
Bigger concern is keeping cylinders sealed and stock block alive.
With your present boost success with E85 on your 4 cylinder you might want to consider staying NA on the 461 and upping compression 2-3 points.
Continue doing your homework!

I really want to go turbo with the 461.
I guess what I really would like to know is if some one can tell me what the cylinder pressure comparison would be with a 11 to 1 motor at 10 psi to a 8 to 1 motor at 35 psi, or is there more involved to think about? If its some of the same maybe it will be ok?
