compound twin sizing ?

[xcablb7]

i have an a5k on the truck and i just traded my camaro for a gt 47 88mm i'll have to get the specs on it tomorrow but, how do you figure sizing for twins ? where can i get a pic or diagram for the boost lines to the wastegates ?

I heard that the primary has to flow twice the cfm as the secondary?

GT4718 is a BIG turbo... I don't know where you would fit it; but, if that is the primary, and as a primary it will support about 1k hp (IIRC about 138 lbs/min), then an appropriate secondary would be a GT4294 (which would be pretty street laggy) or a GT 4088 (streetable).

a5k/4718 would work.. highly recommend puting in waste gates. on min the ak5. the 4718 will push over 1,000hp on a dmax.

soul..

the primary/big turbo goes pasenger front where the overflow tank and bat staed

similar to this setup.

Ok that makes sense, looks like a nice sano install... is 1st pic gt45 and 2nd pic gt4202?

Long time before reply, but I just found this.:bang

First pic is from my last winters build, GT4718, second pic is from MPI setup, probably GT42 or so.
