Mustang Dyno, AWD, 510tq/368hp

did you do a stock run? Dont get hung up on numbers look at the differences between stock and map 2.

Here's the dyno graph

YA that does look strange. IDK man.

 

[Metalmania82]

I never got around to dyno'ing it stock, didn't care too much. I was thinking the HP would be closer to 400 and TQ would be mid 400's going by other's member posts with the same mods. If I didn't know better i'd think these numbers were for a diesel.

lol.

remember all dynos are different thats why you need a base line on that dyno.

Thanks for the help. I'll be uploading the CSV then with the dyno chart once the shop emails me my file.
Should have a video as well.

Definitely looking for some input from anyone familiar with tuning on these cars, especially from @Terry@BMS . The difference between the WHP and WTQ seems to be waaaay too much but I have no idea. Hopefully have everything together here soon.

Seems reasonable for map2 on an MD dyno. What fuel? I see some timing movement so you'd benefit with more octane and/or better cooling on the dyno.

 

[Metalmania82]

Agreed. But I really feel like something's wrong with these numbers. But what do I know!

Thanks Terry. That makes me feel a bit better, everything looking good.
Fuel is 93 octane from Sunoco. What would you recommend using or doing?
Dyno was in a closed room with a single fan, not an open garage door like I'm used to seeing around here. Definitely felt much warmer after the 4th pull and the tech did mention feeling a loss of power with probable heatsoak.

Get a meth kit keeps those temps cool.

Your car was dyno'd in the wrong gear. 5th gear is 1:1 on the 8 speed auto. 4th has a multiplication factor of 1.19. Your numbers are inflated by approximately 19%.

Nice man I made 375whp on map 2 with jun mids and evc with k&n drop in panels.

Doesn't work that way. Dyno measures engine speed vs. drum speed and standardizes for gearing. But, the 1:1 gear generally will be more efficient (less power lost in the trans) and boost a few HP that way. Longer gears mean longer runs which can help or hurt power depending on the situation. Will increase EGT if you're working off a WGDC limit but also work the cooling systems and engine harder so may see more knock/less timing.

So which gear do you recommend using for these cars?
And I know you previously stated everything looked good except for the high temps, but should it really look like diesel numbers?

The problem with Mustang dynos (from what was said previously somewhere on this forum) is that the numbers are not accurate against other dynos unless the dyno operators set them up for the exact vehicle properly. Dynojets are more comparable to each other because this specific calculation is not needed.

I want to go again in the fall after a couple more mods this summer but maybe I'll look for a shop with a DynoJet instead.
This shop has a Jet single roller but their AWD is Mustang. I assume DynoJet is also available in AWD form?

You could unplug your AWD fuse and run on the RWD Dynojet

 

[Metalmania82]

Has anyone else done that and had no issues?

Plenty of people have done it and actually drive on it. Not saying long term use wouldnt cause issues but for a couple dyno runs you should be fine.

 

[Metalmania82]

Might try that then, thanks!
