My trip to the dyno

[Wikkedson]

I dyno'd my car a while back. There is one thing about my dyno sheet that has got me clueless.

Generally on EVERY car torque and horsepower always cross at 5252rpms. All dyno sheets ive seen and all tests ive seen show this.

BUT.... For some ODD reason on my dyno sheet, my torque and horsepower get friendly(cross) at around 4600rpms. NOW how did this happen?!!?!?!

I pulled in 3rd gear. I have 45 profile tires on 16" volk wheels. Im thinking the lower profile tire or the lighter wheel make the trq and HP cross sooner, or did i dyno in the wrong gear?!?!?!

Anyone have an opinion?

Please let me know

I wouldn't worry about were it cross.

it's it generating enough torque is more inportant.
How many FT/LB did you generate and how flat is you torgue curve?

peak was 194, and it dropped down to around 125, thats with 11psi on a t25 that blows oil.

With your turbo blowing oil it will cause you to losse some power.
But I'm not a T25 expert.

yeah, It seems like my car gets slower everyday. And i guess since the seals are gone it really does, since more oil gets caught up in the intercooler everyday.
But i dont think the blown seals would cause the trq andHP to cross there. Ive seen other dyno sheets from t25s, and 16gs where it was at 5252.
So who knows

Oh yeah and how in the hell did you find a 92 GSX with only 32565 miles!!!!!! HOLY CRAP
