Awesome.....Any advice on my 470 build? Looks like all I need to hit 1000hp is 12psi......Cometic surprisingly said the same thing, I should be good till right around 20psi with no o-rings or anything else. Someone suggested E85 for mine, and I hadn't even thought of it at the time, but the more I thought about it, the more that made a lot of sense for me. Just trying to figure out the best static compression now.

I know the A&A trans parts work well. To what HP level, I have no idea, but we have upgraded a number of things with their parts, and have had only one issue and it was with the TA VB....It wasn't set to high enough pressure.


E85 will eliminate the need for an intercooler at least to a point.

As far as CR goes I think the conventional wisdom with boosted engines is the bigger the volume above the piston is, the more fuel and air you can pack into it so less CR technically could have more power potential.

I think it comes down to how much bottom end torque can it make NA before the boost comes on and is it enough to get the engine through that transition and up on the converter.
