1jz Dyno Day!!! 300RWHP/ 298 Ft-lbs

Nah. If the hp was low, the torque was low too. The hp is just a calculation based off the torque. If you were making 330hp, your torque would be the same +/- ~10.

There's been some abnormal cars though. One car made 371hp/420tq. There was more involved than normal exhaust/downpipe/boost up though.

Wow, 420 TQ. That would be super nice! It will happen, just give me time

Nice numbers man..
Take that cat off and you'll get +15 hp more :icon_bigg
How many flywheel hp are the 300 wheel hp on the 1jz?
I think it has the same hp loss (20%) through the dravetrain...

yeah, i am guessing about 350-360 at the crank. 17% is what the computer was saying which would be 351 BHP.

any idea what your a/f was durring the runs? could be where some of your hp is hiding.

was it a stock cat or a highflow? a stock cat will eat a lot of power, a highflow less, but still a bit of hp

i only had 296hp and 294 tq with 2 hr of tuning the standalone. and its running rich and running wastegate i think 14 pounds of bost:cry:

Yeah, i had my wideband running. At peak torque it was around 12 and then at full power it dropped to about 10.5 or 11. I would have to relook at the maps.

I have no idea about the cat. I know it is a 3" cat becuase all of the piping is 3". But i dont know about it. The idiots who made the exhaust welded the cat in, instead of bolting it in, so i cant use a test pipe i already own. Otherwise i would have already done that. I really would like to see what the difference is. I am going to probably have to just redo the whole exhaust sometime. It came with the 1j.

Supra70- is your ct-26 stock or upgraded? Thats a lot of boost creep.

It was a 60-1 ct26. The boost controller wasn't connected so it was just off the stock wastegate spring. Boost should've stayed constant at ~8psi, but by the end of the run, it was almost at a bar.
