DynoDynamics- why you so low?

Hey Guys,
I had my car Dyno'd with the Procharger I1. According to my datalogs, fuel ratio's, PSI and all the data points, the car and supercharger are doing what they should. However, the Dyno was seriously disappointing. Sadly, I didn't have this dyno available to do a baseline before adding the Procharger.
Also, we didn't check the power up to 6-6.2K RPM like I would have hoped and you can see the trend was still going up.

Anyway.. thoughts? Does this look reasonable? Anyone else compare to DynoDynamics?

None, all stock on the engine aside of the I1 complete kit and Procharger tune for stock + adjustments they made based on the datalogs

o ok then that's about right then. Throw some LT Headers, Cam, and full exhaust to start. By the way do you have a horsepower or car goal?

My goal was to get my daily driver car to ZL1 power+, so procharger talks of ~55% gains with the Procharger I1, I was hoping to see around 540 at the wheels but I've heard DD is the heart breaker dyno so I'm trying to understand if the numbers make sense to people here.

Man, that torque kinda falls off doesn't it?

As far as horsepower, you probably shoulda ran that thing up almost another 1000rpms. You're probably right around 500

The torque line is misleading, the Procharger i1 has a CVT belt that changes the ratio for optimal power, notice it gains full torque almost from the start. it keeps a pretty good line until the end. I'm actually not to concern with that torque line.
I agree with you that had the dyno been pushed to 6200 RPM then I should have hit the 500's at the wheel.

I would put some supporting mods on the car with that Procharger and you will definitely hit that mark. But like Gearheaded said I believe your tuner got out of it a little early

I don't think it's misleading, I think your stock motor is robbing that blower of some power lol!

Honestly, you're right on par with the kit claims. You're almost 100rwhp over stock. Def put some supporting mods in there.

Sticking with the stock oil pump?

Procharger needs to breath, Cam, full exhaust including Long tubes, and you will be happily in the mid 500s .

Don't sweat it. Dyno Dynamics are called "heartbreakers" for a reason because they always read low. Take it to a Dynjoet 248 if you have one in your area.

Those are solid #'s considering stock manifolds. They are killing the middle and top end. Congrats on the mods, OP!

All the best,

In my experiencing the DD dyno can consistently read 10% lower than a Mustang or Dynojet. Mustang and Dynojets can read higher or lower than each other depending upon calibration with most thinking mustang read a tad lower than dynojets but thats not always the case. Then there are hub dynos like the dynapack that read higher than the mustangs and dynojets (around 5% higher). This has been my experience in different states/cities and on different dynos.

Thanks guys, I appreciate all the feedback. My tuner said that because I didn't have a baseline dyno that it's hard to really compare apples to apples with my car. He had contacted DD that told him that stock SS's usually get 300-320 on that particular dyno.
Based on the trend of this Dyno, if it were pulled to ~6000-6200RPM it would have likely hit 500 so we're looking at ~180HP addition at the wheels which is what I expect.

The main thing is that the Tuner said it's looking good, the engine is sounding great, there is no knock retard etc. So as people pointed out, I guess my next target will be to help the engine breath. :-)

I'm going to the track on July 7th so it will be fun to see how it does since I'm going to be racing my Dad, he has a Stingray Z51 manual.. I suspect he will have much better launch but it may come down to a drivers race.

P.S- Oh yeah.. on a side note, it was 104 and terrible when that dyno was done, the fuel was on the rich end, the tuner said that likely affected the outcome as well.
