Low Torque @ 702

What would cause low torque? I guess it could be in the tuning but I would like some opinions. I dyno over 400hp but just hit 702 torque maybe thats OK but seems low to me.

Re: Low Torque @ 702

where was your peak torque RPM? What kind of dyno was it? Eddy current motors installed?

2900-3000 RPM and a Dynojet.

Re: Low Torque @ 702

Numbers right on the mark.

tq x rpm / 5252 =hp

(702 x 3000)= 2,106,000


2,106,000 / 5252= 400.99009 hp

Re: Low Torque @ 702

Mine did 404 hp and 727 ft lbs on a Dyno jet. Id say your numbers are good.

Re: Low Torque @ 702

In your sig you have Hybrids and a 38R. What size Hybrids are they? CC and nozzle No doubt your numbers are dead per the formula which I would expect unless something was wrong with the dyno. Also do you have the graph print of the dyno run showing the curves?

Re: Low Torque @ 702

It is sometimes hard to load a turbodiesel on a dyno without eddy current motors to help put a load on the truck. Did they run it in direct and where did they go WOT RPM-wise? That seems like a really high torque peak. Horsepower peaking there would be more logical.

Re: Low Torque @ 702

I have the 200/30% hybrids. Yes here is the dyno print out. Matt I am not sure where they loaded it while I was on it maybe the chart will help. I just thought it was a little low but as said right on using the formula. I was not running tunes for this set up I still had the tunes for the 174/146 SS that I had in with stock turbo that's what I had when I got the F5. The first run was in 80e the other 2 was 140 tune. My icp is good also I have 2800-2900 in 140 @ WOT
