I know a guy with an LS in a gen 3 Camaro with 2 eBay GT 45's inter-cooled on e85 that ran a 7.99 in the 1/4. I watched them tune it on the Dyno live. Pretty cool. I talked to him in detail and all he runs is eBay pop off turbos. He said he has never grenaded one. This was years ago.
The one on mine is off eBay as well. Cost me $800.00 . Before tuning on the Transbrake it makes 8psi @ 3500rpm. With the little tire I think it is going to be a bit much! Im gunna have to work on the launch RPM/Boost. It seems to make more boost down low with the retard set at 2* per lb of boost. The initial timing is locked at 34*. This is where EFI and the ability to fine tune everything is superior to a carburetor in my opinion. I would think almost everyone would agree on that one.
