I Think The Dyno Was Wrong.
 

Well I finally got to dyno today and I think it was off. From what I understand they never even loaded it. My first pull was 569hp and 1080Tq. I ran the ADR comp1 pl10, no smarty and sprayed a 60-70hp shot of nitrous. Then the guy said My tire was hanging half way off on one side and I couldnt make another pull with those tires. that initially gave me hope that it was dragging but it looked like it had spun on the roller. I pulled off and ended up putting stock tires on since I drove almost 3 hours to go. The next three pulls were all right above 540hp with nitrous then the last was only like 471Hp with no spray. Call me crazy but wouldnt it take more than 471Hp tp propel my truck to a 12.85 1/4 mile on fuel only? I was really expecting to be over 600 on spray.

how much does it weigh?

Last time I weighed it it was just over 7200 I think.

It looks Like a heavier run that your numbers. After our conversation , I got to thinkin about it, Look at all my dynojet runs , I'll post up the videos. You can compare from there. Secondly, It dosent look like the truck was very straight. It's hard to say though, The atmosphere has alot to do with the run, What was the weather like?

Anyway, Call me later, We'll discuss it more!

You got it buddy. Like I said some sounded like they should have been alot highter but some were dead on. They might have loaded the dyno for them. I know it felt relly stong.

the horsepower calculator on compd says around 550hp if your runnin a 12.85

The Calculator here On Diesel Bombers Shows 556 bud..

I appreciate it guys and I'll agree with that calculator anytime. But the fact that i didnt use nitrous to run that 12.85 and I had to to make the 569 doesnt add up to me.

ive heard dynojets run on the low side when it comes to hp numbers

No, Normally dynojets are what most diesel's base their number on. The mustang reads lower, the dynocomm's and other's can be set to read much higher!

Compared with other setups pete's numbers do sound a little low. Maybe not that much low but still a little low. Secondly, He's not using a very big nitrous setup!

I'm thinking maybe around 40 low
