HP with tune

[moonjim]

Just wanna know what anyone thinks: The 6.2 is rated at 411hp from factory. Whats your guess with a cai and 5 star tune? I know the dyno graphs are on here, but just wanna know flywheel, since thats probably what the 411 is?

Lots of things will depend on the percentage diffrence.
As in transmission, torque converter stall, gear size and tires so on.
In general, subtract roughly 20% of the FWHP # to achieve an estimated RWHP #
Roughly 15% for manual.

411 is FWHP: so (411FWHP x .80 - 329 RWHP)

I'm sure you'll hear numbers as most have gone this route.

Mike at 5 Star said he'd one day post a table like this below (example taken from the F250 Super Duty tunes) for the Raptors, but he has yet to follow through.

You could estimate power at the crank (and gains at each RPM) with a nice table like this.

Most manual now run @ about 12% loss.
