0-60mph in 3.7 in 1st gear  , that's insane. |
compression ratio on the LS7 is 11:1. a turbo won't be going on there unless the compression is dropped, which lowers the power.
of course, it won't be TOO much of a power loss....and the turbo would more than make up for it.
now, why stop at a turbo? why not twin-turbo?  |
You've been brainwashed . You can run a turbo on a 11:1 static compression ratio engine if the other parts match. Get the intake valve to stay open longer during the compression stroke and you're dynamic compression ratio would be well below that of a "low compression" engine.
Also, why twin-turbo? Last time I checked the singles were the setups putting the most power to the wheels and for good reason. Unless you've got a flat-crank v8 or some ultra fancy cross-over headers for your twin turbo there is no way possible for a twin to be more efficient than a single. I'd take a well designed single over a twin in a heartbeat. The twin just sounds cool :P
I don't know about the IRS. To me it doesn't take an IRS to make a sports car, although it does help. IRS just tells me it's better for handling the crappy roads . Smooth and the IRS has very little advantage over a solid rear.
What does this car do in the 1/4 mile if it's doing 0-60 in 3.7s. That's gotta be well into the 11's if not better. |
brainwashed, my ass. 11:1 is do-able for a turbo, but i'd rather have lower compression to ensure that the motor won't grenade itself.
as for the twin-turbo setup, it's a matter of personal preference. if you want all-out balls to the wall power, a huge single turbo is great. but if you actually wanna drive the thing and enjoy it (and not have ridiculous turbo lag), i'd go with a twin-turbo, a small turbo to have quicker power off the line, and a large one that takes over when it's finished spooling up.
