There are a number of different kind of dynos. They all work the same, but have different "methods" of figuring and they all claim to be correct.

Each and every dyno will read different. Some a LOT different (i'm talking 30% and more). I've watched trucks dyno on the same style of dyno but a different dyno (different place) with the EXACT same mods and throw down very different numbers

For example........a mustang dyno in lynden Wa took place in Oct.ish Most of the pack at that dyno (mustang dyno) through down in the 500-600 range....... In Spokane WA in November (mustang dyno) a majority of those same trucks came to dyno again..........virtually all of those trucks had not changed a single thing. Most of that pack that was in that 500-600 range through down 400-450 hp. The 900-1000hp trucks in lynden through down 700-800 in Spokane. Identicle dyno, uncorrected numbers... the whole 9. Should of been the same. Elevation wasn't much difference, temperature was actually colder in Spokane, etc...........

That day, the trucks that I dyno'd the same (within a few hp), ran in the 490-520 range in Lynden.

Dynos are very accurate but yet somehow very very inaccurate.

I'd like to know myself. :lol:
I've got enough good parts thrown at it to do ok, but idk.

When I first started messing with the truck I called a place in Milton WV (An hour or so away) and asked about their dyno and they said they didn't do dyno testing anymore. Last year I called up Enterprise Engine in Thornville Ohio (2+ hours away) because they're actually a diesel shop and had a chassis dyno. Found out they sold it because people didn't use it enough to make money with it. So I have no idea where a reasonably close chassis dyno is. :? I could drive several hours to a diesel show and put up with all the flatbillers and common rail former Honda ricers to dyno my lowly first gen... :yuck:
Heck, I think they moved Buckeye Blast from Hebron Ohio to somewhere even farther away. Mass Diesel always brought their dyno to it. I got to see Taco's truck put down a blistering 268 horse one year on it. I've either had the truck torn apart or had to work the last two times they had that show. :roll:


It's on jackstands right this minute anyways. I've got some work to do to the brakes, etc. but its going to have to wait a few months because I'm trying to buy a small farm/house and don't want to spend any money till I close on it.


The good thing about Dunbar's Dyno was it was a constant the you could use to compare trucks from different areas. I may have ran on it in Ohio, and you ran on it in Indiana, but the dyno was the same. No using the high or low reading dyno cop out.

I don't know if anybody mentioned it (I didn't completely read all these posts), but I think there are big differences, with the way a manual trans, and a NON lock-up automatic trans put power to the rollers. Given the same engine, the manual will put down bigger numbers, I think.
- I figure the manual, obviously, won't have the slip of the NON lock-up converter, and as a result, a better load is put on the engine, getting the turbo(s) to spool a little earlier/easier.

. . . if that makes sense.

One thing I have learned is that my money is better spent using a dyno as a tuning tool (the last two or three times I've been on a dyno, and tuning between runs, I left with at least 50 more peak horse power).

The track shows what it can really do. ;)

If you go by CompD's HP calculator . . .

The 6400lb cinder-block going through the traps at 103.35mph gives us: 479hp at the rear-wheels, or 520hp at the flywheel.

or . .

The 6400lb cinder-block making the pass in 12.67 seconds gives us: 516hp at the rear-wheels, or 560hp at the flywheel.

Who cares, it's fun as crap! :lol:

Yep.... a dyno number is just that, a number. In the "new age" (as I call it) diesel stuff has been around the "dyno" has been the way to show who has done the most and who knows the most. However, a dyno number means squat when it comes to throwing something down the track, pulling a load up a hill, making fuel economy, or pulling a sled the farthest. HOWEVER, it does allow one to see what their hp/tq to rpm curve is and what this mod or that mod did at this or that rpm. As long as the exact same dyno with the exact same variables are used.

Now all that aside.....dyno numbers are a good way to gain bragging rights around the diesel world....and why fight it. :lol:




Especially, if after 21+ years.....no one has broken 500rwhp on fuel only with a 6bt with a 12mm ve hanging off the side of it. The first person who does it will have one hell of a bragging right.....21 years is a LONG time.

If a number was all BC was looking for throw a getrag in that thing and he would smash 500 like it was glass. That's not his thing though. He wants to embarrass people at the dragstrip with a green brick. 8)

Am I dreaming this or was Bill G over 500 with the ol-rusty truck on fuel, never mind he had a 14mm pump.

Now does it count if we put in a 4mm cam plate?

Back in the day GLHS (iirc) posted some of his findings on cam plates over on DTR. Stock 2.8 flowed the most cc but at the lowest rpm. 4mm cam plate didn't exist back then though I don't believe. I don't think a pump with the 4mm cam plate will hold together long anyways. (Just mho)

No, unless it is a stock set up (h/r, camplate, etc..) it doesn't count (to me anyways)

I've got it........can't believe I didn't think about it before.

Take a couple oxygen tanks and plum them into the intake........imagine how well things would run with pure oxygen as opposed to the atmosphere's 21 percent oxygen.

That wouldn't be cheating would it?

Running pure O2 to me would be the same as running water/meth...you are supplementing by allowing a better burn...but I never said it would be cheating ;)

My thoughts behind it are.... if done right... there is no "wasted room" from the other atmospheric elements. It would be 100% oxygen and diesel. The amount of oxygen you would need would be retarded, it would be very expensive to buy that much oxygen for a 5 second run.

In theory running 100% oxygen would also reduce emissions a bunch.
