Competition New Dyno Numbers 1020 H.p

[KLockliear]

The fact of the matter is that nearly 100% of high end engine development is done on engine dynos, not chassis dynos.

The thing is, almost all of the people in this forum, and most others for that matter, are not doing engine development, they are doing tuning. For development, an engine dyno is great. For tuning, the chassis dyno is as good IMO.

I can see that.



What is so pathetic are the childish comments you see here about engine dynos and on COMP461s thread about his engine development program.



Then I comment on that and get accused of having an "attitude" and "no business will be sent my way" like somehow there would otherwise have been some sort of monster convoy to Center, ND to do engine dyno testing.



Josh, don't kid yourself, I never would have seen you as a customer either.

 

[JLackman]

Oh for the sake of discussion would someone please post;



what brand of chassis dyno this was,

what the correction standard used was,

and exactly how the dyno's DAQ handles the weather inputs



on the Engine Dyno vs Chassis dyno thread?



Thanks.

 

[Sled Puller]

Why would North Dakota need a dyno, anyway? :-laf



That sounds as silly as setting a pulling track up in LA.

 

[AFarmer]

nobody ever mentioned (a daily driver) is this Gus? just talked with ed last night about you, he was very impressed



if this is you

Yeah its me. Somebody earlier in the post, oko, whoever that is said something about a dailydriver. Just poking at him for what he said. Yeah-- I heard Ed said that he was done with the 'gas' and was looking to twin up that Dmax. Never say never but that's pretty close to impossible. It's good to see a number like that come from NC. I hope to slap down a better number in the next couple of weeks.

I don't have to kid myself. Anyone that owns a business, SHOULDN'T go bashing around like you have in your first 30 posts on a forum that is 20,000 Diesel Enthusiasts strong.



As far as you thinking I would never "need" such a thing, or want to do such a thing. Well... . I may or may not, but I know people that May. I'll refer them to other places. Honestly my goal, when I can build the funds is a nice daily driven 700hp. The engine will be out to do some of the things I want to do.



Mike's Custom Trucks in Northwood North Dakota namely. He has BOTH types of dyno's. He talks softly and carrys a big stick in these parts.

BINGO!!!!!, some one just hit the nail on the head.

1020 to the wheels - simply awesome!!







Man - that truck brings back a lot of memories. Back when Brian S. owned it... I did the KDP on it... what a pain. It had a hydraulic pump for the plow mounted under the hood and it was leaker (or rustproofer!). :-laf



I remember driving past the truck on my way to/from college - it sat in the Fairbanks Auto Body (Fitchburg, MA) used car lot for a few weeks... and then Brian bought it.



Matt

The rustproofing didn't work... .

I will guess that you aim part of that comment at me, and thats ok, you can say and feel whatever you wish, it doesn't bother me. Engine dyno's are great for engine development, which is all that Comp seems to be doing. My jab was directed at Comp cause this stuff doesn't have to be as technical as he is making it out to be. We now have a street truck, making power that is very similiar to his, with probably 1/4 the money spent and not a single high tech gadget on the thing, and better yet, this truck is raced constantly. This truck is fully capabale of making more power also.

Preach on!! My thoughts exactly!

Scott... ... Come on down. I know of a Krystal right there in Albany. Used to eat breakfast there.



Tim... ... . It was really good to meet ya and tell a few lies. The truck is just a work of love and labor. You've done a great job on it. And the power, what impressed most was the 818 of the trailer. That is something that just ain't done. Jeff's been working the "buns" off for it and you drive in, there already. Just a super job.



We'll see you in Albany and watch what you and Jeff can cook up. It's gonna be good.

Crap! Well, despite the rust it still goes like a scalded cat...

Oh GROAN...



Look guys, I'm sorry for blustering in here with what looks like such an anti-chassis dyno attitude.



Dyno accuracy is a pet peeve of mine, especialy when one routinely sees references to dynos being 10%-12% different, same manufacturer same general location. Differences in corrected numbers as high as 10% are inexcusable in my opinion, yet it gets blown off with the comment, "accuracy doesn't matter, repeatability is More Important". Then add to this things I have read about chassis dyno operators using whichever correction factor their heart desires, well, it's MADDENING. I've had engines from big name builders here on my dyno put out 10% less, I had engines that went from here that went to two other dyno shops in the Detriot area, one was exactly the same one was about 5% higher. I'm to the point of questioning every corrected number I see, and that is pretty sad.



I believe there are reasons for these corrected number differences, and no excuses for the reasons.



Would you buy any other thing associated with high performance that could be off by up to 10%-12%??



It's mind blowing to me SuperFlow would allow a very public 10%-12% difference between two of their SF901 dynos to continue, if it were me I would fix that, or die trying.



Well, enough from me, for now anyway.

 

[bgilbert]

Who is this guy??? Jeez. . lets all go out and pull our engine so we can dyno it on an engine dyno...

 

[RoadGoesOnForever]

Do any dyno operators monitor fuel temp? If not, then they are missing out on a huge factor in how much power an engine makes besides barometer, air temp, etc.

Congrats on the numbers..... simply AWESOME !

 

[JLackman]

Please????

Also, was this upsweep downsweep or steady state testing.



Thanks.

Thanks.

My Dyno Jet 248C, inertia, uncorrected numbers. SAE was 1003hp.

 

[JFaulkner]

Hey JLackman do you sleep in a hyperbolic chamber like Michael Jackson just to be sure that your atmosphere is always consistent? Wouldn't want you to feel 10 to 12% different each day.



I personally don't know why Comp even wasted his time putting his engine on a dyno since the atmosphere will most likely be different in 2010 when he actually gets the truck to move.
