I've never hooked up to a dyno and was wondering about how much hp and torque you all think I'm getting at the rear wheels??

325 + maybe another 130-25% thru stock tranny

Not sure on this comment, as the 325HP is at the Flywheel, and not at the wheels. So, you can take the 325HP, add 100-130HP which will give you roughly 425-455 HP at the flywheel, which depending on if you have an auto or 6 speed wil depend on how much power you are losing through the drivetrain, as well as DRW or SRW.

The % numbers are just a guess, and I will give an example:

You take your truck and we will you use 450HP @ the flywheel as an example, and say you use 25% deduction as your formula, follow me so far? That comes out to 112.5 HP loss, right?

Now, take a more heavily modded truck (extreme here) Twin Turbo's, Injectors, stacked boxes, modded CP3, TST R49AP box, etc....so now we are seeing let's saying 850 HP at the flywheel, right? Now, take your same 25% Deduction, and now you are losing 212.5 HP through the same drivetrain, follow me still??

Now, tell me why the 850 HP motor is losing 212 HP through the same drivetrain that your 450 HP motor is losing only 112 HP???? Not possible. If you have the same drivetrain, just becasue your motor makes more power does not mean it is going to LOSE mroe power through the drivetrain, follow?

My point is, for the MOST part, it takes a given amount of power to turn the trans, driveshaft, rear end, tires, etc...and not a % of what your motor makes.

Make any sense to you? I am a firm believer in THAT theory, as opposed to saying, oh yeah, takes 25% of your total power to turn your drivetrain. I do not buy that. That is my .02, and I am NOT starting a war. Just trying to put aside the % is the given rule for power loss, still follow?

To me, it takes the same amount of power regardless of how much power you are making at the flywheel to turn the drivetrain, and not a % of your total power.

So, you running a 6 speed or auto????

Auto tranni

Stock tranny with stock converter, you are going to lose a little more power than a built tranny with a good converter. I would say you would lose between 100-125 HP from the flexplate to the tires.

That being said, my guess would be around 360-370HP, give a few and 700-725 TQ @ the tires. And possibly more, I like to be conservative.....

notice I said stock tranny that would be the reason for the high % I know the 325 is at the crank,the 130 is for his mods at the crank,which is 455,at the crank minus a 100 horse thru the drivetrain is 355,put it on the dyno garantee im within ten horse.

The stock 04.5 is 275 (approx) Bhp. With a mp8 and others,, probably 75 to 90 hp. So I say, 365 max. With my truck when I was running allmost the same stuff except for I ran a bd instead of a mp8. I hit 348 on the dyno. But my truck is the 305 555 engine, 260 stock on the dyno

Oh and one more point, you are 100% correct kdiesel. A stock tranny will lose way more hp than a built tranny, due to slippage from the tq and all the rest of the way.

Oh, OK, just misread your post, cool....
