I dynoed yesterday on a dynomite dyno and put down 346 rwhp and 289 rwtq. Oddly enough I was on a Dynojet last Saturday and put down 361 rwhp and 368 rwtq I think. Since last Saturday I turned off my COT on my tune and got a new IAT sensor because mine was broken. As you can see from my old graph my AFR was below 10.3 after 4400 rpm. Yesterday I got my AFR to 12.7 NA and 11.3 on Nitrous. Any thoughts?

This has to be the saddest performing setup I've ever seen....

I didn't mean it as a flame towards you or anything like that. I'm just saying something is seriously wrong.

Edit- From looking at your A/F, you're in serious need of a professional tune.

I would spend the money and get the car professionally tuned on a Dynojet. I've never heard of a Dynomite dyno.

Dynomite Dynamometers are one of the most advanced and sophisticated dyno's available. They have been around for 30 years!

If you want an inflated number...get to a Dyno Jet. If you want to tune and get a realistic number, get to a Dynomite, Super Flow or a Mustang.

Ksett

That sounds great except what do you compare it to when everyone uses a Dynojet?

waSStock

You wanna compare a number or make some power? It doesn't matter if a dyno says your making 32 warm fuzzies to the ground, as long as it repeats, displays improvements and losses.

Its just a number. If you really want to compare chassis dyno numbers, just use the same dyno, same test procedures, same temp oil, tranni fluid, rear end fluid (and viscosities), tire pressure, fans and strapping force.

I hear what your saying, its just near impossible to compare this stuff with any type of "real" accuracy or relevance.

You're not understanding what we're saying. He needs a professional tune. Look at his graph, look at the A/F ratio. Yea, his numbers suck because of that too. No goddamn 6spd H/C car makes 367rwhp, EVEN ON A MUSTANG/SUPERFLOW/DYNOMITE

i agree with the A/F numbers being wayyy off.

LOL.

That's just damn funny.


As for the original poster, ehirst83, I'd venture a guess that the Dynomite dyno is a load bearing device whereas the DynoJet is not. I don't know if correction factors were used, which could change the numbers as well.

Either way, the A/F is way off and it needs a tune.

Thanks for agreeing Jake, gotta help point these guys in the right direction somehow all the while weeding out the retards and their "knowledge"

I don't need a professional tune. I got my Air Fuel to 12.7 NA and 11.3 on nitrous with my HP Tuners. With a 2-3 tenth leaning out on the street I figured I would stay safe rather than sorry. The reason it was so low on the dyno jet was that my IAT sensor had one of the wires pulled out and I am running in Speed Density. I just wanted to know if anyone else had seen real low numbers on a Dynomite. I gained 22 rwhp in an hour of tuning from 326 rwhp to 345 rwhp. That's what I needed to see was the difference. Now I just want to see my dynojet numbers again to see how far I've come with a new IAT sensor COT disabled and a tune.

Just talked to the owner of the shop where the I dynoed. I guess he had the settings wrong for the correction factor. He is going to email my corrected graphs but the numbers are still low. NA I put down 365 rwhp corrected and 455 on a 100 shot. Still about 60 rwhp lower than anyone I've seen with my same setup. Also I ran at the track on Friday and went 12.6 @ 111 w/ a 1.97 sixty foot. Do the math and w/ a decent 1.60 sixty I'd be around 11.83. That's NA at 4300 ft. elevation!

Did you adjust your timing tables as well?

ehirst83

iTrader: (5)

Yes I did

Here is an attachment of my first dyno run with a 100 shot. Compare that to my last dyno on the Dynojet and you can see my frustration.

Yes, the Dynomite is a real ball-buster. Load bearing dynos will do that to ya.

Asmodeus

And 111 in the 1/4 on a H/C car is way off I'd think??

My car made 367 hp on a dynojet and 323 on the Dynomite.
