What is actual HP @ the wheels on our trks. I know my valve cover says 210 but curious what wheel would be???

 

an E4OD typicly uses 75-80 horses to turn, a zf trans uses approximatly 40, the c-4 uses 40, the c-6 uses 70, so you can figure it out from that. if you run an auto you are looking roughly 135 rear wheel and 170 for a stick.

 

COON u r fast numbers are kinda depressing..

 

yeah but look at what you are turning, look at the size of your torque converter and the size of the trans, also think of how hard it is to turn the rear yoke with it jacked up, you lose alot of power through the drivetrain thats why engine dynoes suck and chassis dynos are the truth tellers

 

I think those numbers are quite low. I have seen a few dyno stock trucks and if I remember correctly they came out with 170-185hp at the wheels. oh and when it really comes down to it. torque is what makes your truck move so HP really doesn't matter! Well ok it sort of matters. LOL

 

i have an article from early 1999 and they tested the first 99 model sd with the first superchip, pedal, intake and propane. they did a dyno pull with it stock, i will upload it tomarrow. the truck was a 6-speed so it will give you an idea for the sticks but remember you lose a lot more horse power and torque turning an auto

 

What happened with the upload? I'm kinda interested in learning the actual numbers. I would like to think that they are more then what you said,but if you can proof it then I bet I will be more able to talk the wife into stage two and tw chip.LOL

 

lol, sorry i forgot about it, here is the article in the house, the other on a 99 7.3 is in the shop, i'll get it tomarrow, but this gives you a good idea of the comaprison, 50 horsepower drop in a 6.0 and 127 ft pounds, and the torque shift has better bearings then a e4od, so assuming it is the same, a 97 psd would have, 175 rear wheel horsepower and 348 ft pounds

 

That is interesting to me to know. You say it is the bearings and the size of the TC that steal so much horse power in our trucks. Is there some way to get around that or is it just better to go with a manual?

 

not only the tranny but the diffs as well, the full floaters we have are good for as big as they are, the trannies depend on the overall size and friction areas inside, alot of the newer stuff uses roller bearings instead of thrust washers, that is the main thing you can do, it lowers heat and reduces the ponies used to turn it
