Inflated dyno numbers, or factory freak? I'm 100% stock with a removed intake snorkel, and I find it hard to believe I'm making higher torque numbers at the wheel than what's rated at the crank.

Here's the dyno sheet. The last three runs are with TC off.



Here's a video of the very first run, which was 168/175. TC was on at this point, after turning it off numbers started getting better. Dyno was a Dynocom DC1800X.

Nice that's pretty awesome. I knew 180 whp wasn't true but its nice to see that the numbers weren't that far off.

I think it was rhythmnsmoke who said it best. Use the dynamometer as a baseline to measure improvement upon modding. Every dyno is different, and what you made on this dyno will be much different from any other you do pulls on. Example: World Racing's stock tC2 made over 180 whp on Church's dyno in CA.

agreed also every engine is just slightly different too

if its not a dyno jet i wouldnt go by these numbers.

Also, dont forget to factor in barometric pressure. Sea-level vs altitude can make all the difference in the world.

And temp and humidity factor in a well don't they? Most dyno runs I see are around 80+ degrees, these are at 59.

Basically when they sell you a car and they tell you how much hp it should have. They are talking about hp at the crank not the the wheels. But not every engine would have the same numbers. It basically say that 180hp and 173 tq, would be around what the average engine should have, but dont mean it could have more or less.

MrMexi2011TC

Hey were did you get it dynoed? Maybe i can go to the same place if its here in stl and see what the differences are if any. Oh and how much??$$
I see the address there on paper. forget the first question.

Jiggavolt

Yeah...that's why I put "whp" and "wtq" in the title.

The place I took it to was having a special, three runs (the guy let me do five since I didn't change anything or tune) for $60. Decent deal. Dunno about typical prices.

MrMexi2011TC

Oh man, cause i want to put it on the dyno. I can get it on a diff dyno at a tech school for free but i want to see the difference between cars on the same dyno.

There's a dyno place out in St. Charles that I know a bunch of people use.

MrMexi2011TC

Yea, there are a few but i want to see what the same dyno pulls up on two Tc's. But there is dyno at Ranken tech were i went, and i might be able to put mine on after i put it on the same dyno in alton.

Chewsifer

Did you use the dyno during the show? I was there in my tC.

MrMexi2011TC

No, i did not run it. I was going to take it but i wasnt able to go to the show. But im cool with the instructor that runs the dyno, so he prob let me put it on after classes.

Chewsifer

Cool deal. I need to put mine on the dyno and see where she starts at stock.

MrMexi, if your instructor was cool with it, I'd drive out to Ranken Tech and run mine as well so we can compare on the same dyno.

MrMexi2011TC

Ill get in contact with him here when im able to. I just spoke to a guy that goes there and he said that the instructor no longer runs the dyno, but ill see if i can get it on there somehow anyway.
