TRX is probably 610-615whp. I can't see a 3.5 getting there. Nobody has been able to do that (with a warranty).
No way TRX is at 610-615WHP. Before I bought my Roush Raptor I had 2017 Roush Supercharged F150 Stage 2 650HP. It did 510WHP on the dyno and truck was probably 1500lbs lighter then TRX. I would put TRX at around 530WHP at the most.

I agree how weight would have an effect on 0-60 times, but unlesss the weight is rotating mass I don’t see how it would have an effect on a dyno reading.

Based on what Raptors dyno at. They lose about 20% at the rear wheels, as compared to rated HP at the crank right? Apply the same to the TRX and that’s like 560whp. Now the TRX is moving more mass in a Dana 60 rear and the tranny, etc could have more rotating mass as well.

This sounds closer to that 530 or very well maybe a little more HP number as mentioned above.

The Gen 1 Raptor drivetrain loss is more, I'm at 560 rwhp and the Tuner told me that's around 710 to 720 at the crank.
I only get 4.1 to 4.2 seconds 0-60 on a good day. Would be better if I did headers.

I'm pretty sure the TRX is close to 600 rwhp to get that low of a 0-60 time at that weight.

Times don’t lie. That HP number
Is probably up there. That’s not too bad on drivetrain loss on the TRX then considering it has a heavy power train to support it.

Plus the Gen 1 only has 6 gears were the TRX has 8, so it most likely has higher ratio gears for first and second.
Still hoping someone comes up with a way to put the 10 speed in a Gen 1.
I would bet my 0-60 would close to 3

Gen 1 actually has a shorter overall first gear ratio compared with the TRX. The TRX has a slightly shorter 2nd gear ratio, but not by much. Not seeing where you’re coming up with 3 seconds when the TRX with more power and similar weight is doing 3.7, which is already incredibly fast for an off road truck. And that’s with launch control and full time 4WD as well. The slightly shorter ratios of the 10R wouldn’t net anything close to a full second in 0-60 time.
