Dyno Results
 

Well the Z was dynoed today and I have to say that I'm disappointed. I havent studied each and every dyno result from everyone on this sight but I do feel that mine are quite low.

With that being said, its weird because my car totally runs its *** off. It really pulls like crazy and I could not be happier with its performance. I love the car.

My car is an 09 Base 6MT with about 5xxx.xx miles. Mods are K&N drop ins and ARK Exhaust.

All pulls were in 5th gear.

1st Run - 256.02 - 232.09
2nd Run - 275.29 - 235.81
3rd Run - 252.88 - 233.85

The runs were done on a Dynojet. Temp - 56 degrees

I will post the graphs later on.

Thoughts/comments?

Dam, why was there such a huge jump in run 2...then it died down again.

1st run was done at 8:55, 2nd at 9:02 and 3rd at 9:05. She was HOT after that third run!

That is a big difference between the 1st/3rd and 2nd run. Maybe not as accurate as you might think. There could be hope that your Z makes more power!

Im no dyno expert by any means. Does a dyno need to be warmed up? I was the first of 5 cars done today.

Why 5th gear?

no, that should not affect the dyno measurments. the big jump in power between the pulls is odd though... it is possible that the dyno operator changed some parameters between the pulls.

is 5th gear 1:1 in these cars? i know that in my '03 cobra, all dyno pulls were done in 4th...

From threads I searched 5th gear is the 1:1. It is possible the operator changed some things. I can understand if it were a few hp/tq off. The other cars dynoed had very minimal if any changes through runs. A Shelby GT500 (supercharged and could heatsoak) made 532/537 and 534/534. He would definitely suffer more from heat than the Z.

Are you 100% sure all 3 runs were done in 5th?

100% sure.

hmm... sounds a bit fishy, while all dynos will read differently, they shouldnt differ that much. I've never seen a Z on this board dyno less than 260 on a dynojet in stock form, with your exhaust you should be dynoing much higher, closer to 280-290. Yours look like mustang dyno numbers.

Definitely fishy.

That is weird jump in the runs. Do the american version of the Z not have a govner? i couldnt dyno my car in 5th cuz it would have hit it. So i had to dyno in 4th.

Supposedly our 5th gear gives us the best numbers, i wouldnt know though, i've just dynoed in 4th. Still have yet to dyno with all my mods.

not all dynojets are inertia types they do make load cell dyno's they shop by my house has one a nice awd version at that. It would be stupid for dynojet to only make one model of dyno and never change anything, we really need to describe the dyno's we run on better. the dynojet at beyond redline here in town is one of the lowest reading dyno's i have ever seen.
