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???

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.

Chris.

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.
