I searched Google and this site... was unable to find anything. You guys have a bead on some dyno charts for 325/610 stock trucks?

 

There is some info about stock # on here you will have to do a search. From what I have seen they are about 280-290hp at the rear wheels and right around 500tq at the rear wheels if that helps any.

 

I did search... couldn't find anything. I'm looking for the chart itself (not just the peak numbers) because I'd like to see the torque curve. This relates to another thread about TC stall speed.

500TQ at the wheels eh? 100HP for drivetrain losses is no joke. I'd also be curious as to the dyno charts from a manual vs auto.

 

My truck dynoed 280HP/554TQ stock. Horsepower is 225 at 2100 rpm and climbs to about 280 at 2700 rpm then drops off. Torque is about 550 at 2100 and is flat all the to about 2700rpm.

 

Well I know there are some stock 04.5 and up charts posted, not sure if here or TDR. I can't find mine it was too long ago. But my numbers stock with 315s were 272rwhp and 503torque I think. Around 17% power train loss through the TC/Transmission. The 315s may have been a small amount of that, but that seems to be about normal for the stock tc/transmission. I don't think it is necessarily unique to Dodge, just manufacturers trying to protect drive train.

 

Thanks for the responses so far guys.

RamWheelsBy4, I believe the 315s had a pretty good impact on your numbers. They raised your final drive gearing and added rotating mass.

 

I dont know if this is what your looking for but this is what mine did.
Stock with auto and 3.73 gears.

 

Super!!! Thanks!

That long, flat torque curve is great. Seeing that, I also don't think a 2,000 RPM stall speed for a TC is all that bad. Seems like most of the power is made between 2,000 and 3,000 RPM.

 

Mine was 267 and 492, but it only had 1601 miles on it. Everyone says it should go up a little after break in. Dont know and dont care. It wont be stock for long.

 

Here is another:


TQ peaks about 2400 and HP just short of 3000. The sloppy TC keeps the trans in one piece, the emissions down in the lower rpm's, and the trans in fluid coupling until the speed is up. The TC stalls about 2200 rpm's and the ECU defuels at 2100. Not the best setup but using TH and getting the TC to lock as soon as possible helps. A better TC helps alot in getting the power to the ground but like everything else it increases the risk something will break.

 

Interesting comparison between a non-broken in truck and one that has some miles on it.

No 6 oh no: would you explain how or why the ECU defuels at 2100? I'm a little confused on that one.

 

Well I am not sure if the difference is broke in or not, but the chart of no_6_oh_no seems more like the ones I have seen for stock engines. The torque generally does seem to peak by 2000rpms or sooner on what I have seen.

On mine it does automatically defuel but at about 2950rpms with stock programminng. Just my .02.

 

Looking at that second chart you can really see why a 2200RPM stall is higher than necessary. These things have some significant power starting around 1600RPM.

 

My G56 did 286hp and 528tq with 1600 miles on the ticker.

 

Could also be the differance between a good ol 6 speed (miss mine by the way) and the POJ auto.
