Im looking to dyno my car this week for some tuning, any shop recommendations?
I will be at full function Tech @ 4:30 on Wednesday getting my MKIII tuned. Wanna stop by and see how they do?? I like that shop, they are kool..ofcourse my tuning can give u an idea if u are a 2jz...im tuning a 1jz...so u can gauge..twinturbozs said:Im looking to dyno my car this week for some tuning, any shop recommendations?
I dont know much about mustang but I am fairly confident dynapack is accurate from what I have seen and experienced. For example I went to the track a couple days after dynoing and measured acceleration rate from 1/8th mile to 1/4 and the math matched almost exactly.What we found, from our two-wheel-drive tests, is that the Dynapack and Dynojet give surprisingly similar readings. If you compare a 7-second pull on the Dynapack with a third-gear pull on the Dynojet (which happens to take 9 seconds), the charts agree to within about 2 hp. The same is true when comparing a 15-second pull on the Dynapack with a fourth-gear pull on the Dynojet (fourth gear, in this case, takes about 17 seconds). The agreement between dynos was similar on both cars.
actually performed this test in an effort to determine some sort of reliable conversion from one measurement to the other, but it appears that no conversion is necessary. As with any dyno, however, before comparing two different dyno charts, you should know the conditions under which the test was performed and be absolutely sure, in the case of the Dynapack, that the ramp time is similar.
TunaRollZ said:Yes Racetune uses Dynapack.
ATP is still around, but last I tried to go there, they said their Dyno was closed to the public from now on. They're only using it to develop products
Mustangs usually reads about 15-20 % lower than dynapacks or dynojet .TunaRollZ said:The general trend is that Mustang dynos will show the lowest rwhp numbers, dynojet will be higher and dynapacks the highest (of the major three dyno types).
Technically the 'dastek' system used by UTEC puts out the highest numbers I've seen though...1400rwhp on a stock 350z! that's *gotta* be an accurate system! haha :ugh2:
Most people use dynojet as the standard...it doesn't really matter though as long as you keep it consistent between the one you want to use to compare w/ other numbers...

FFTEC uses Mustang.
Racetune uses Dynapack - I think that's what it is called - they mount on the hubs.
DNR Performance - On Industrial in Hayward - Not sure what they use .
I've used Mustang Dynos and Dynojets all my life... I've only witnessed the dynapack in action.gixxer_drew said:Sport compact car October issue 2001 says

But like any dyno you can set it up to read whatever you wanted to if you want to fake numbers.
Yeah...that's a really good point to mention on this thread too actually.gixxer_drew said:But so that just means that it can read innacurately if you set it up to, but thats true of all dynos. Just didnt seem like a fair statement when you first said it but makes sense now.
I was thinking it would be cool to do a different dyno at the next meet since we did dynapack last year.
