I might've confused the issue. Depending on atmospheric conditions and on how well a given type of dyno loads the engine the engine generates a given FWHP. About 83% to 85% of the FWHP gets transferred to the rear wheels as RWHP and about 97% to 98% of the RWHP gets transferred to the dyno rollers as DRHP.

The DRHP is what's given on a dyno sheet and then you have to work the above percentages in reverse order to get the RWHP and the FWHP. Then you need to take the atmospheric conditions into account and calculate a correction factor which estimates what your FWHP would've been on a "standard day" such as an AAT=70 F and an AAP=14.7 psi.

The importance of understanding the above complications comes into play when comparing dyno runs on the same truck that were taken at different times and or places, comparing dyno runs between trucks, and in using dyno runs to predict drag race ETs.

 

Gene, I don't know when the next time I'll get on a dyno will be, but I will keep the information in mind for even comparisons. Thank you.

I'll read more on the K&N filter.

I do not want this to be a discussion on izzy's post. If further discussion is requested, it can be off this thread, thank you.

I thought my question on the post was clear. I asked for dyno advise, a topic i thought many people would be interested in. I listed my truck details and asked to people to keep it simple.

 

Ernest is one to keep it nice, simple, short and right to the point.

 

AZ Dyno gave me a print out of my best numbers. In drive, starting with the engine preloaded, best HP is 210. Best Torque 448 Ft Lbs.
I guess I was a little disappointed with that HP after seeing so many big numbers from others. But I have the 35" tires, and no chip so I hear that's repectable output.
We did other runs in first and second to see if the numbers were better.
There were no correction factors.
The weather was perfect.
Strokin it pinned the tail I'd say.

 

Goddamn im good

 

Well dang -- I figured he'd be closer to the 220 side of the teens. It's all good. Sounds about right for a stock truck.

I was razzin' ya' on the wiper mod, but do think about ditching the K&N. ANY dust in there is BAD! It should be completely clean in there, aside from some oil if you haven't done the CCV mod yet. Here's what a K&N cone-style CAI equipped truck a buddy of mine looked at had in the tube (notice the finger swipe through the dust -- that's VERY bad!):
