that aint right......i think

[smilie=e: payed for and downloaded a dyno-sim software thing. Just put all the info i know about my trucks engine.

All the stock specs except for a few things i modified (like roller rockers, cold air and such)

well, since its a truck, and looking at the factory dyno specs, the torque is higher than the hp rating. But, according to the dyno, with the truck weighing in at 3,500lbs and a driver at 180lbs, with mild porting, roller lifters, rockers and camshaft, cold air, 1 inch throttle body spacer, Multiport Fuel Injection System.

Come out with a grand total of *drum roll please* 269 rear wheel hp at 6,750 RPM and 227 ft lb of torque at 5,250 RPM.

Which would be cool if the base line torque at the flywheel wasn't already 230 ftlbs.

Cause at the flywheel, the things got *aparently* 292ft lbs of torque @ 5,250 (that figure could be the only accuret thing besides the info i poped into the input) and aparently the hp is at an insanely large 345 hp @ 6,750 RPM


So if any of you have a desktop dyno with like a truck option, or something a hell of a lot more accuret than mine, PM me your e-mail and i can give you all the info i can on my engine.

But if anything, i can dream.......and print that out to fool some idiots LOL

I am a little confused....normal state, I guess. But if you are working on hp and tq, what the hell difference is there between a truck and a car? The motor doesn't care....it doesn't know. So, my question would be.... are you putting cam specs, head flow and all that crap in, or are you using factory specs? Once again, why does it make a diff if it is in a car or truck? Unconfizzle me?

numbers sound pretty close to me.....one is at the fly wheel and one at the rear wheels.... there is about a 30% loss/ difference through the tranny

well, from what i hear, the way the cam is designed, its made to give off more torque than hp since its the stock cam in it still. So yes, i'm putting in the stock cam and valve train specs since the only difference is roller rockers. Everything else is stock. So i figured, with its current set up from the factory (more torque than horsepower), i thought that the out put would be the same, with me having more torque than hp, but still, both being higher than the stock baseline.

So, in short, it has a truck cam, trucks (i'd think) make more torque (mainly on the bottom end) and have a higher torque rating than Horsepower rating. So i figured, since its still stock cam, there'd still be more torque gained than horsepower.

And just driving that thing, you can tell its a very torquey (eh?) kinda motor. Its got hp, but alot of torque behind it.

So in my opinion, i find that odd that it shows more hp than torque.


but maybe thats just me.

Sorry, I missed the part about it being stock to modded comparison. Trucks do usually make more torque from the factory, no doubt. I assumed, wrongly, that you were building a fresh motor for the truck. That is why I lost the point on it. I would blame my medication, but quite frankly, I am too confused by what I just wrote to say anything more.
