Newsflash...

The Dynojet 248 is the de-facto standard for comparison pulls. You can go get on a load cell and dial in another couple hundred hp any day of the week, but what you can't do is manipulate a Dynojet 248 intertia. It is what it is.

Now for a guy running stock (or modified stock) compound turbochargers there is no excuse for not making street boost on the dynojet. That 6.4 should have made any number you wanted, if not, somebody needs to learn how to tune, or make the required changes to wastegating/VGT control because my 7.3 ran right before him and made the exact street boost I pulled in running, with an 88mm first stage compressor. If I had wanted 70, 80, 90 or more lbs of boost it would have been a simple request made via keyboard, as I have done numerous times before on that exact same dyno model.

I don't think the guy was getting anything from the spray. IIRC, he did something in the 6teens. I had no doubt that he should go right at or over 700, and was looking forward to seeing it. I was shocked myself when I heard what he had pulled. But it wasn't a dyno problem.

The dyno was exactly where it should have been. Neither high, nor low.

I was with him in Chicago a couple months back and he put down 782 to the tires on a real international dyno with one that actually puts a 40% load on the truck, and garmins is made for a low rpms cummins motor. He had small nitrous pills in it that day but still should have showed more than he did. There was another 6.0 there with a turbo and other bolt ons and he said he usually hes around the same hp as ben, but he only made like 630 or sumthin like that too. He'll be in nashville this comin weekend for the dyno day up there, and I will tell u his numbers after this coming weekend!

BTW, it's spelled "Garmon".........And, how is a dyno "Designed" for a specific motor???

Id just excuse his statement from him being from Statesboro, or if he's just a student, well...

[bwood2006]

Ha sorry I misspelled Garmon wrong, so u must be stupid too seeing as how u graduated from Southern!

I was hoping someone would catch that.

i have seen the truck pull well over 700 more than one time on internationals dyno and he had the sheets to prove it. I have actually seen it on three different dynos . I dont know what was wrong with the truck or dyno, but either way i have seen over 700 with my own eyes... and you really cant hate on a student being a mechanical engineer

Yea....thats what I was thinkin. A 7.3 puts down 633 fuel only(!) & then the 6.4 guy claims the same dyno is predjudice against Fords? Not. He just didnt bring the HP. Tune it & try again.

Moving right along.... Was that 7.3 still single turbo??

[bfp2006]

whats the major mods to the 7.3? I give him props! u usually dont see those making those kinds of numbers? BTW i think what the 6.4 was saying is it was tuned on a loaded dyno so it didnt make the numbers he was expecting....but it doesnt really matter i have seen it make more. something could have been going wrong w the truck i dunno? i know something wasnt right.

[triton]

the 7.3's have come a long way. Brian has the dyno record for a 7.3 at 680hp on fuel only. He's almost got it running into the 10's too.

hey i will say the truck was off...didnt feel off on the way there nor on the way home. do the math something on 35s that weighs 8850 with me in it runn ing a 790.00 ran that number two days later.. made 609 on motor before ??

[Charles]

I don't think the spray was working as it should have on the 6.4L. I expected it to go 700's.

But I will say this, 180hp doesn't just disappear, and you aren't going to lose that kind of power going from a load cell to a 248 inertia with a truck running stock or at most modified stock chargers (compounds no less) and on top of that spraying.

Nitrous Oxide doesn't care one bit how much load is on an engine. You don't have to spool a blue bottle. So coming up 150+ shy of the expected when running spray is quite a stretch.

It's much more likely that the spray simply wasn't working properly.

The only other option, is that you take the 525ish the truck pulled on fuel last year, and add a 100 shot of spray to it, and you get 625ish. But it sounds like he feels that he is much stronger now on fuel, and that the spray is worth much more than 100hp.

And in reality, it should be. 700, even 780+ from a 6.4 on spray is not uncommon. However, the one at Jeff's simply wasn't doing it that day. Which is also not uncommon, for any truck/engine.

Sh*t messes up sometimes. Solenoids fail, so on and so forth.


We're not talking about a truck running a big single that couldn't spool here. We're talking about a stock charger truck, right? Stock compounds no less?

Mine's been running my same old compound setup for coming up on 3 years now.
