I guess what you might be looking for is: Assuming a 10% difference from a dynojet

Before LT2 Intake + TB + Cam on the Mustang dyno:

413.1 rwhp
429.3 rwtq

After mods on the Mustang dyno:

510 = 96.9 rwhp gained
472 = 42.7 rwtq gained

pretty good bump over stock + 100 HP.

Does that seem about right then?

I am not on the same dyno as before, My car dyno'd on a dynojet at 459 rwhp and 477 ft/lbs

I was assuming a 10% difference between this mustang dyno and that dynojet.

But, I'm having a hard time believing I gained almost 100 rwhp with just the LT2 + TB + Cam?

Well most cars dyno around 415, not sure how you got 459, seems insane.

459 on a dynojet, without the LT2 + TB + Cam.

The base pull was never done before I got the first set of mods. So don't know what the dynojet would say but given the gains shown at 85 hp at the crank, it would have base dyno'd on a dynojet for about 395 rwhp.

On a mustang dyno assuming 10% difference it would have base dyno'd for about... 355.5 rwhp. Note: The difference between a mustang dyno and dynojet can range from about 5-15%. I assumed the average of 10%.

So all the mods together on that mustang dyno would have given me a gain of about 145rwhp give or take a few from stock.

I am asking if those numbers sound about right on average?

[Christian1LE]

Yeah sorry, no idea I don't know or have any experience with those mods to give you an answer.

Yes the Mustang dyno can be a heart breaker but, then it just a tool for tuning and with a good tuner very capable. Many variables are used in making that tune and some say the Mustang dyno may be better. I know my numbers really don't match up with others with a similar build but, the seat of the pants performance I get says otherwise. Good luck and happy running on your new build.

^THIS. Glad to hear you got everything sorted.

Good numbers in my opinion and not all Dynjets read higher than Mustangs. There are a whole lot of factors that go into to it. Temps, DA, SAE, Standard on the day of the pulls. I actually talked to Chad this morning and he was telling me that his Zr1 made lots of pulls on a Dynojet before he got his own Mustang Dyno and the numbers were very close to each other so it's not always accurate that the Mustang is stingy in every case. He did drive it on the street also to make sure it was all good and was going to get it on the street again before you pick it up. He was very happy with the results so I know you will be also.

Noted: I was trying to be more modest and say 125 and be happy with it, but if I get higher great.

Will find out when the weather turns some time next year.
