OMG OMG dyno numbers mean everything!!!11111!!! Take it to the track and get real numbers

 

its not the dyno when you dont walk a stock cobalt. there is something wrong with ur tune. time to find a new tuner or there is something not right about your motor. do u have all your compression? something is fishy

 

Ha, I was there today too.

Stage 2, zzp intake, gm exhuast and pulled a 177hp.

Brett's Skyline only got like 204.

There was a Mustang with dyno sheets from before showing 620 HP, and he only got 430HP on his run.

 

so then its the dyno

 

Yup. There's the proof.. Take it somewhere else!

 

thats what happened to me where i took mine...i only got 208 hp with 2.9, s3 h/e, 42's, and dual pass...then went back after going to the mods in my sig minus the tvs, it was a 2.6" on m62 and only got 218hp and 211 tq

 

How much do you want for the stage 3 if you decide to sell it?

 

A local guy down here (05inPinson on the forums) had ZZP stage 3, ZZP tune and 50 shot of Nitrous, after getting tuned by Vince @ Trifecta that thing was faster and ran better.

He got re-tuned by Vince a month or 2 ago.

 

how's your intercooler pump?

 

Ok, I'm not disputing the mustang dyno reading lower then dynojet...
But what I don't get is.

Isn't Horsepower horsepower? It's a combination of torque (effort) and RPM (distance and time)

That WHY does the same car run significantly diffrent HP numbers on diffrent dynos?

That's like stepping on a scale and weighing 250 pounds, getting on another scale and you weigh 208 pouds.

I'm really missing something here...

 

dyno's need to be calibrated

 

Well aperently the Mustang's calibrations are WAAAAAAAAAAY off...

I do remember when I had mine dynoed, that the computer took
tempature, humidity, barometric pressure, and then used that
to calculate my HP. Could there be someting in the weather
that caused it?

 

or maybe since it was a new dyno, the workers didnt know how to set it up properly

 

It was a dyno day. Must have been 40-50 cars that all went, so the dyno was not setup to each individual car.

 

Why do vehical spific calibrations matter?

Shouldn't it just be measureing how many times per second the wheels can spin the drum, with a measured ammount of resistance added in the drum? That's all they SHOULD need to measure horsepower?

I'm really missing something
Why not just measure the speed of the drum, with a known resistance, will give you RPM and Torque! THEN, multiply them together and divide by 5252.

Who ******* cares what kind of car it is, or if it's an old lady on a trycycle!

I'm really missing something here...

 

well here is a list of things they couldnt have done, also that one car with proven dyno sheets, failed too. so im thinking they didnt know what they were doing

 

Wouldn't surprise me if they didn't know what they were doing.

 

Word of advise....I had the same setup and then a few days later my motor popped...I would check some stuff out and not get on the car at all...

 

I disagree
