Hi Guys,
Great build! I am thinking of a similar twin MPT70 .68 Ar turbo set up on my forged rods, pistons, 6.0 (truck block) 364 CID motor in my 74 camaro with car pro flo XT intake, cnc 'd 317's, braked turbo 400. She will be about 3400 race weight with me in it. A lighter car may spool faster.
With the .68 AR exhaust about what rpm does it spool? My car will see heavy strip use with some street. Hope it spools early with those twins and pulls all the way to 6500 RPM or so! That way it will be fun on the street with an early spool and still pull good at the track! About 6500 is a good shift point for engine longevity!
Those Twins are producing great power at mid boost!
