Thanks!
I can't help but laugh at the 1.40 60' and 10.0 combo.
Man, that's pie in the sky stuff for my heap right there!

When it went 133 mph I hurt a piston.
When it went a 1.43 60' it hurt the transmission.
I can never seem to get all my ducks in a row.... but I'm workin' on it!

So 810 at the flywheel?
What should that look like at the wheels?

Yes Flywheel HP, can use the other Wallace calc that gives you rwhp and fly but thats miles out cos they only rate a 10% loss. Can't see you ever working out hp losses through the drivetrain accurately as too many variables to take into account of.

Thanks.
I hope in the future to also see what the difference is between a rollerized 727 and this 46RE. I've heard good reports about performance gains from the swap.... but I do like my overdrive and lockup.

Are you just plugging numbers into the wallace calculator, or do you have this converted into a spreadsheet?

I'm inputting the numbers straight into only 1 of the Calcs but using some race knowledge and actual time slips along with it in doing so to verify accuracy of calc.
