power loss through drivetrain?

[all4gss]

i'm trying to figure out is how much power is lost through the 200r4 and the differental in these cars? I thought a rule of thumb was 25-27 percent. An optimistic goal is to have 500 hp at the wheels. I've seen charts on what turbo, stall and injector size you need to attain certain hp levels... i assume those levels are estimates of flywheel numbers. what hp level should i shoot for using those charts to get 500 down to the pavement? thanks for your time,

I would be curious what is lost through a TH-400 vs. 200r4.

500 HP down to the pavement, you are going to need a built 200-4R. I'd contact PTS or Century for more info.

For drivetrain loss, I'd guess around 18% through a 200-4R and stock 8.5" and a locked up converter.
