I went to get a dyno pull today and was surprised on the results. First run it was 245 at 6200rpm. After a cool down second run was a whopping 264 at 6700rpm! All done on 4th gear. I knew I had a factory freak!

 

Depends if they used SAE.... If they didnt then odds are its not accurate... Sorry to burst you balloon

if they did, then you do got a freak on your hands

 

He tells me a stock 6spd Z dynos around 245 or so. For an auto 235 or so. This was done on a Mustang Dyna

 

Ya Sports Compact Magazine dyno a 2003 track model @ 249 HP and 240 Torque.. So he's about right with those #'s....

They say Mustang Dyno's are more accurate... So those are pretty good #'s for a automatic with just an exhaust....

 

Yeah he says the Mustang dynos lower than the Dynojet

 

Lets see the chart, and I don't buy that Mustang dynos always dyno lower than Dynojets. I have seen otherwise personally. There are so many factors that go into the numbers. So if you have the chart, can you post it up. Plus I don't know how the max power went up 19 hp and moved up in the RPM 500 between runs.

 

damn, i'm happy for you...my 5AT w/the mods in my sig dynoed 241 rwhp on a dynojet. Can't remember which RPM it hit it at...I need to san the dyno sheet and post it. But congrats on your freak

 

I try to post the chart but it doesnt download into the site. I think its too big. The max torque was a disappointing 214.2 @5500rpm. It was cool out and there was a fan in front of the car. The shop has the fastest VQ Z in the world.

 

Did you run it on those 19s?

 

yeah my car with my mods only got a "crappy" 269whp, so maybe i should get that exhaust?

probably if i dynoed right afterword on the same dyno in NYC, I think my numbers would be much higher than 269whp

 

hmmm... here is my dyno:

 

Those are some decent #s. I do drive my Z hard. Especially after the exhaust install.

 

shouldn't it be dyno'd in 5th gear?

 

no the stock 17's

 

Not for the 5at, i think 4th is correct.

 

4th for the 5at is the 1.00 gear. The 6spd 5th is the 1.00
