Question Rear Mount twin 63mm???

Will twin 63mm work good with rear mount setup on ZO6??? How laggy will it be???

The car have built 346ci H/C Now but I'm planning to go big CI Down the road 408ci maybe 427ci???

Is the Turbos small for those CI???




Thanks in advance and all replies are welcome.

from what i have seen you may have some lag issues. guys have made over 1000rwbhp from STS kits using GT35R turbos. i think this would be a good starting point for a 427 build.

have a look on the ocrvette froum for more information. there is loads out there.

I ran twin 60-1's t3/t4 Hybrids in the *** in 2004... and they were a lil laggy for my liking, and that was with a 408. They hauled *** though and nearly 700 hp at 13 lbs. Peaky and late coming though.

Nothing cures a laggy setup like a TH400 with a good stall, only have to spool it once. Little tough to put a TH400 in a Vette though.
