You're missing the validation step of deriving the correction factor: take the test car back to the Dynojet.

Personally, I'd leave the correction factor out and state the fact of the type of dyno it is and how that relates to other types of dynos. Otherwise, the correction factor used and the method of developing it is always going to be a variable.

The Mustang is def. better suited for tuning, you can't deny that. The Dyno Jet is better for bragging rights. Best of both worlds would be to dial the car in on the Mustang and take it to a Dynojet and cover all the holes.

As long as you are paying for the dyno, i'll take it.

I'll pay to have your car baselined. We'll do it when I do mine.

You think? I am after all "not a mechanic and slow" according to your boss. Neither of which I can argue with when it comes to working on cars. But I did run 12.5's with 337RWHP of my own tuning and with me doing all the wrench work.

What did you run you run at the track this last weekend? High 10's with 461RWHP? 11's? 12's?

I'm actually in no rush to get my car done. But since you put it that way, how about this weekend we dyno your car? Again, I'll pay Brian's fee. This might be educational for all concerned.

Tell Kyle to show his dyno graph if it's killihg you guy's that I'm making that much hp. Don't you remember jason putting down 425rwhp at 14 on a bad motor. Voska put down 459hp, but you didn't question his numbers. He has the same turbo, but different motor so what makes you think that are # are wrong.

Hey Zavier,

Didn't mean to attack you. But you poked at me so I pokey pokey back.

Yeah, I sort of remember Jason putting down 425rwhp. Wait....it's coming back to me! I was tuning it at the time, do YOU remember? BTW, I still think Jason's current engine is the strongest of the bunch. This is after talking to Rob about it.

Vosko is a nut. If anyone put down 459rwhp, he did, but on a dynojet, again. I don't like his chart...all jiggly like. Yeah, I bet I could get more out of his car.

Point is, you are manipulating the stated numbers of the dynojet with a 18% correction factor to get where you are now.

The testing methodology to derive the factor was incomplete with a test BACK to original results...the dyno jet for comparision of a new test subject. (As I under stand it, you took a car that dynoed on a 'jet, strapped it to the 'stang and backed into the same RWHP numbers? THEN applied that to your car? See how your car has to go to the 'jet to confirm your factoring?)

I am offering to help you complete the test and get on with life by paying for your dyno run. I figure you guys will use it to test and better develop your correction factor. I still advise that you use it as a disclaimer like others have when posting with Mustang numbers.

You guys have a **** setup for tuning. Forget the bragging rights stuff. Let the customers roll around and do that for you.

I didn't post the first numbers, 450 on first run. I took some fuel out and hit 461, so i stop because I know my fuel pump can't handle that. I'll put another fuel pump in this weekend and try to go over to brian's and check the numbers. Who has the side feed 850, let me know if you want to sell them

Girls, stop arguing about it.
My intent was to get numbers off both dynos for accuracy. Im sure zaviers numbers are very close to a dynojets, give or take a few HP.
