Does anyone have a dyno graph of a stock X50? A potential buyer for my car swears that tourque does not build until 3700. I am sure that is wrong but need numbers.
Thanks,

The manual says that peak torque for the X50 is 457 lb. ft. from 3500-4500 rpm (pg. 206). The manual also has a dyno graph (pg. 212) but it seems to be for the non-X50 engine.

Although peak torque is from 3500-4500 rpm, I'm sure usable torque has a broader curve. Hope this helps.

 

Thanks !

 

I just had my bone stock X50 dyno'd by Tony at EPL prior to upgrades.

I attached the PDF to this response. Not sure how that shows up on the board, but email me if you want the file.

 

Perfect...just what I was looking for! Problem solved, and Thanks!

 

if those numbers are for a stocker than that mustang dyno reads high, but it is irrelevant as you are using it for comparison of before and after.

looks to me that you reach max torque between 3600 and 3800. So your buyer is under the impression that it does not boost till 3700, but you are starting to boost way before that, you just reach max boost at near 3700. looks like a good curve to me.

 

I don't have enough info to say whether or not the dyno reads high, but it is EPL's Mustang Dyno and the car is stock with 14k miles on it. Tony did say it was one of the strongest stock X50's he has seen.

What will be more interesting is how it pulls with mods toward the end of this week. Stay tuned.

 

Thats reading over 400hp at the wheels stock ? So over 500hp at the fly ? As previously said, ok for comparison purposes, but no way is that the car's actual bhp.
