I'm willing to toss mine on a Dynojet and Mustang dyno.
FOR SCIENCE! Just need days off.
The high torque is due to it being in 5th (1.3:1) gear not 6th (1.0:1). A simple rough calculation converting the ratios would give about 330lb.ft of torque.
Regarding the torque converter locking up, look up torque converter torque multiplication. Basically when a converter is unlocked it acts like a bigger gear driving a smaller gear by fluid. Once it's locked, the ratio goes back to 1:1 reducing the torque output.
Not to mention press cars would have been thoroughly "run in" as compare D to cars fresh from production. The engines would have free'd up a little I'm sure
Sorry, but it doesn't really work that way. Gearing/mechanical TQ multiplication doesn't influence dyno measurements as you've described. If the engine theoretically output the same TQ at the same RPM in say 1st gear as it did in 6th, the dyno would read nearly the same result. All the dyno knows is how quickly you accelerate the drum/hub from RPM X to RPM Y over time.
As you're probably aware there are several Dynojet's around CLT, so shouldn't be tough. I have access to one at my buddy's shop in Greensboro if you need an alternative option. Also 3SX/Performance Factory in Concord has an AWD SuperFlow and they're doing a dyno day on 8/10. My experience on their SuperFlow is it reads 3-5% lower than a Dynojet (though they like to refer to it as a heartbreaker).
I was thinking Pro Dyno, since I'm not off on the 10th, but I can still go up there. Probably should, since I think I'm friends with employees on facebook.
Quarter mile trap speed is the bogie to watch because it's far less impacted by off the line traction limitations than 0- 60 times and quarter mile ETs.
Litchfield’s Simple ECU Tune Boosts 2020 Toyota Supra To 420 hp And 440 Lb-Ft
Obviously blue is not the stock tune. Would love to see the rest of that graph!
No it was their first tune. Made 336hp 368 stock
I may get laughed at but I want to see a side by side of a Premium 3.0 and a Launch Edition on the dyno. I know they are supposed to be the same but how will we ever actually know unless someone dynos just a premium?
Sorry, but I'll take the word of mainline. Different gears do give different torque readings unless the dyno is setup to correct them. There is a shop in my area that is known to make insane numbers of torque because he does 2nd gear pulls to inflate the numbers. You could also simply change the tire size on the dyno configuration and see how it can affects torque.
Even if we disregard how dynos measure torque, the car's ECU could simply output different torque numbers at different gears. Only way to know for sure is get a car on a dyno and test it in different gears.
