...In a 3720 lb. "race weight"(with driver)GTX? The Wallace Calculator is not even close to the MP listing,in my Mopar Performance manual! ALL educated guesstimates are welcome! Fastest the car has gone is a 11.19 @ 120 mph. Thanks in advance for your info! Randy B.
Randy here is what the moparts said my car should be making. But it says i should of ran a 10.90 in the 1/4 with (Your Rear Wheel Hp Is: 533.52) but in the cool fall air i ran a best of 10.68. So i don't know how right the program is. mopar65 :beer
That thing is way off... the numbers it says for RWHP is close to flywheel but then its still off

My original 512 C.I. pump gas low deck made 612 HP at 5600 RPM and 644 Ft lbs at 4500 RPM. It ran 10.69 ET at 124.6 MPH at Woodburn corked up with the air cleaner on the six pak. That was with me in it weighing close to 3400 Lbs. wet, corked up with the air cleaner on, 4.10 gears with 30 inch tall tires The torque converter can and does makes a huge difference on our cars I ran the car at Woodburn several times this summer, it ran 9.96 at 134 MPH corked up on pump gas. This motor made 727 HP the last time it was on a DTS engine dyno at 4300 Ft elevation in Klamath Falls, OR I broke my ten inch custom built converter two years ago, I put in a new T/A 8 inch race Hemi converter with no other changes, it made the car way easier to drive and race and pick my car up .2 ET and 2 MPH in the 1/8 mile

The few times I have run my #'s on a program they all seem to be close as it says I make about 600 to 625 at the flywheel to run 10.70's at just over 3700 lbs. Ron

I have made 468 - 500 at the rear wheels on different dynos ..but I have gone 10.67 at 125 with a racing exhaust and 4.10 gears.. to slow the car down I put 3.73's in and my full exhaust and MT drag radials and the car went ....10.67 at 122 lol at 3750 with me ....you should see your first 10 !!!! at Norwalk and then some
Yep about 470 rwhp(570fwhp-18%=470ish) would do it!Its simple math,not rocket science.

Randy, my Satellite on the dyno normally shows 405-410RWHP. Best et is 11.09 normally runs .12-16 MPH is around 118.9-119.75 car weight last time weighed is around 3775lbs i have a 5200 stall and with any stall you won't see a true hp.i will normally look at adding 15% puts it in the real ballpark.Means about 525-535FWHP around 20-25HP should give you a tenth.If you get around 100FWHP over me you may exceed your hopes good luck Tex

It will be interesting to see what it makes for power and what it runs. Mine is very similar at 3750 lbs. with me in it and runs a best of 10.63 @ 126 and normally runs 10.69 to 10.73. I have never had it on a dyno.

I normally run 28 x 14.50 Hoosier Quick time pro's I just ran the 275 60 Drag radials for a weekend but they did work good for me. My car is basically all stock 45 year old leaf springs some inexspensive gas shocks. It has a best 60' of 1.49 which Im sure could get better with some better suspesion parts. I was guessing mine makes 650 to the flywheel but could be off.
