Default Still waiting for a proper dyno of the is350

dyno jet dyno, with an sae correction, 4th gear pull.

get cranking guys. I'm guessing stock numbers should be about 255rwhp/245rwtq. the only other dyno thus far was a dyna pack dyno, and untop of that, it was a manufacturer dyno as well so you can basically disregard the data.

FYI
Here is the drivetrain ratio for the IS
As you can see the 1:1 ratio for the IS250 RWD is 5th gear and 4th for the rest. 1:1 ratio is suppose to be the ideal for doing a dyno test. Some times it is hard to it in that low of a gear because when you hit the gas hard it wants to down shift.
This might be the case on the IS250 RWD.

I think the IS350 is rated under the current SAE standards, but I'm not entirely sure.

Hey, did you sell your cobra or trade? I traded my 03 cobra in on my IS 350, took alot of flak about it but it was a good decision.
