GTSpartan said:Crate engine = racing engine = no emission cerification, no 70,000 mile powertrain warranty. If you want to compare racing engines look at the GTSR motors. 800 hp N/A and will run a full/near full throttle for 24hrs. You can't compare a aftermarket crate engine to a production one. The V-10 is very detuned from the factory and has been proven to be almost unbeatable against the worlds best in international racing. It's not a drag car, it is a raod racing car!
The reason they have 8.3L is because they don't have a BLOWER. They just use different ways to make power. Also, lets not get into the whole cost argument, it gets real old. Peace :thumbsup:
Hahah, I knew the crate engine vs production was going to be brought up. Anybody can build a big motor to get big power. The challenge is getting more out of less. And the blower issue has been beat to death. It's all volumetric efficiency, like increasing the displacement to get more combustion.
The 5.4 is making 600hp(I have the dyno) with the s/c, take it off and your still looking at 450-500.
