Can you get to 400 without turbo or super-charger

Crash

Ah geez... I nap for an hour and see a billion things to respond to in one thread... LOL

OK, MightyBoo, I live in Los Angeles, and the muscle cars I see out here are not just garaged. There's a LOT of them out here that are being driven like they were meant to be. Trust me on that. I see races all the time. In Compton, some of the best races go down. 10, 9, and sometimes 8 second cars race down there... The street races there NEVER lose their allure... Especially when both cars are doing wheelies off the line... Yeah, people can get hurt and no cops almost never show up.

Lightweight flywheels don't add HP at all, they reduce the amount of potential HP lost through the drivetrain. However, since we're talking about N/A that won't make it to 500HP crank, a lightweight fly wheel is NOT going to be a weak point in the system. LSx motors make 500HP VERY easily so yes, in an LSx application, there's no need to use a lightweight flywheel. Also, keep in mind that an LSx has plenty more torque (345Lbs+) and therefore can get the drivetrain spinning a lot easier. The VQ can use all the help it can get to speed up the revs.

Multiplier does depend on the motor. LSx motors LOVED mods. Little mods made big differences and every mod did help the other quite a bit. The VQ, not so much. I think that other mods to the VQ won't help each other enough until you FI the motor anyway.
