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.

NA = 744HP Power to Weight Ratio: 4.29 60 Foot E.T. : 1.32 1/8 Mile E.T. : 5.97 1/8 Mile Trap Speed : 113.78 1/4 Mile E.T. : 9.47 1/4 Mile Trap Speed : 142
93 jet = 1004hp Power to Weight Ratio: 3.18 60 Foot E.T. : 1.19 1/8 Mile E.T. : 5.41 1/8 Mile Trap Speed : 125.73 1/4 Mile E.T. : 8.57 1/4 Mile Trap Speed : 156 260hp to gain a second?
We had a guy hold the mph record in Super Modified with a 67 Camaro (N20 BBC 509ci motored car)> 7.61@184mph!!..was a Lenco + a lightweight car though, wallace only showed it at 176......N20 is cool stuff!

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.

139mph/3550 = 788fwhp on the day, thats approx a 20% loss on dyno figs on the day> Power to Weight Ratio: 4.51 60 Foot E.T. : 1.34 1/8 Mile E.T. : 6.07 1/8 Mile Trap Speed : 111.98 1/4 Mile E.T. : 9.62 1/4 Mile Trap Speed : 139
I don't have my time slips from 1990 but my last but 1 run in the '69 10:1 SCR 446ci Cuda, I ran 10.7@125, stock very heavy 6-pk bottom end,(pistons 900gms, rods 1100gms) 2.14/1.81 906's, 4500 verter, 850DP, Team G, 2" f/wells, CC .650"/290@.050 solid flat cam, 4.88's/14x32's, ladders/coil-overs, stock front w/90-10's....3000lbs all in, 60 Foot E.T. : 1.49 1/8 Mile E.T. : 6.75 1/8 Mile Trap Speed : 100.68 1/4 Mile E.T. : 10.70 1/4 Mile Trap Speed : 125 = 484hp 60 was actually 1.46

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.
