Can you get to 400 without turbo or super-charger

Phimosis

Using this logic, the VQ engine should already be tuned to it's prime as it came out all the way back in 1994. If you want to argue that the VQ37 is a new engine, it came out in 2008 just like the LS3 did. And the LSx motors did have good cam and tuning. Back in 2001 the 5.7 liter stock Z06 was making 405 hp and by 2003 with aftermarket cam and blower, people had these motors making 700 whp. Sure, the VVEL is more complex, but smart people can reverse engineer graphics chips with 20 million discreet circuits in a 2 year time frame. Remapping the rate of rotation vs rpm of the VVEL and making fuel maps is a piece of cake in comparison. Don't take this personally as an attack on you. I am only ranting because I'm bitter that you can ALREADY buy a Camaro from the dealer that makes 560whp (660 at the engine? 2 months after the car hit the showroom floor?) and we can't even get a Nismo Z yet that makes 15hp more than the base model.

I think there is just more R&D in the aftermarket for American cars, which is somewhat baffling because European and Japanese manufacturers sell lots of cars all over the world, where American manufacturers only have good sales in North America.
