Yeah probably ones with as little of dust as possible...

Kind of off that note... does anyone know if the 2009+ fuel tanks are metal inside with a plastic shell, or are they just molded plastic now? Thanks!

Good luck with the build and keep us updated. I am not aware of any block failures from boost and several builds have been 1000+ hp at the crank. There is a truck that will be racing that summer that will likely be the highest output from any new gen Hemi, but with a partial block fill for strength. (using a FR2 blower) I think the head gaskets would be the first problem to show assuming the rotating assembly is properly built. Denny @ Sharadon figures my engine should hold 20 psi if detonation is kept in check.

I am also kind of leaning towards 61mm or 64mm Turbos... I might go 64mm just incase if i get bored with it I can turn up the boost a little... I think 57mm or even 61mm turbos might run out of umph up top... what yall think?

If I go 64mm What Exhaust A/R do you think would be best... .50 A/R or .68 A/R? (I can get those same A/Rs in the 61mm too)

The 6.1 crank is forged.

Twins are not needed on these trucks. There is plenty of space (unlike a car) and we don't need high boost like a small engine to make big power. A single large T4 housing will make more than what the drivetrain can handle. I've seen a few twin setups using T60-1 units on older vehicles.
