No way. Around 500-520whp on a DJ. He already went to Switzer's dynojet when he had around 400whp on his mustang dyno. He put down 450-460whp on the DJ, however the torque was multiplied even more oddly. I specifically remember horsepower being up about 50whp. Torque jumped something like 80 ft/lb though.

Dave ran 128mph which in in the DJ world is around the 500whp mark. 550whp and up should be at least 130mph, but I mean this is all nonsense. Lets just wait and see what our cars do on the dyno, the track and most importantly.. the STREET!

 

Yeah I cannot wait...

Between 30 and 31 lbs. peak of boost at 5000 rpms. 93 ~4 gal and C16 =5 gal fuel mix.

 

What psi and gas?

 

why does your TQ dive down like that

 

Do you mean 4gal 93/5gal C16 or 4gal 93 and 1gal C16 for 5 gallons total. Im assuming 4 and 5.

 

Either way great numbers but to me those numbers dont do anything because who is going to keep mixing 4 gallons of this and 4 gallons of that unless they race all the time and have the mixture all set up

 

Are you serious?
Take a look at every Evo dyno on this thread. They all go down. My torque numbers on this graph stay above 300 Ft. Lbs. from 3700 rpms to 7200 rpms. That is very good. What is even better is how the car stays above 400 whp from 5000 rpms to 7200 rpms. And it is allways above 300 whp from 3600 rpms to 8000 rpms
Lets focus on the positive, man. Why allways look for flaws?
Not just because it is my graph, but this is one of the best graphs you will ever see. Is near perfect. What else do you want?
Dawm!

 

Very true. Thanks. That is why I got a Meth kit ready to be installed and set up at above 28 psi. The car will be runing this numbers everyday on the street.
Problem solved!

 

I cant see the rpms on the dyno graph. It looks great but you still didnt answear my question. why does it fall off instead of stay flat like your HP. The graph is great and to you.

I just want to know the cause of the tq drop off im still learning here. Will have the same result with my 2.3 stroker. Is there a way to improve a more flatter tq cure of is this the result of the turbo

 

Bigger turbos will hold the torque line more flat, but in return you get more lag and less initial torque. Thats the tradeoff.

 

^ding ding ding

It's amazing how many people do not understand this concept.

The only way to keep hp climbing is to keep the tq constant or decreasing very slowly. If more people understood that hp= tq*rpm/5252 it would be much easier for people to understand how and why dynographs are shaped.

I re-scaned the image and re-posted it with a little better resolution.

Sorry about that. The torque goes down with the boost tapper. As the tapper begins, and boost start to drop off from the initial spike, then torque also starts to drop. Like Soon2BEVO says, the larger turbos have more lag and make less torque at the begining until they built boost and then the torque hits. Since the larger turbos flow more air and can maintain more boost at higher rpms, the torque for them remain flat like after they attain full boost.
Good luck.

 

04awdturboevo,

Good numbers but what Mustang Dyno do they have? Is it a AWD500SE? If so I have to wonder how it compares to ours as even the simple weight and HP@50 numbers are entered incorrectly. MD has a program they give you with weights and HP@50 on it. Just curious, not busting ***** or anything. The power you are making is VERY high for a reflashed ECU and that turbo. My guess is the dyno is altered compared to ours.

 

I just went to their website, it is the same dyno we have...............

When we dyno here we use 3625 for the car weight and 15.1 for power at 50 mph. We also have the settings for roll weight and parasitic drag set up just as it was from the factory calibration (you can see these and are the ones easily changed).

As long as you are happy with the power that's all that matters. They are only numbers and your numbers are great.
