We have a stuska water break engine dyno for the stuff in my Sig. You are saying at 3k to 7k at 500rpm per second would take a dyno session 8 seconds to ramp up from 3k to 7k and you would not make power at 1000 rpm per second?

Yes, that would take 8 seconds but most motors don't have that wide of as power band. Try it.
on my comp motors I dyno in the range I run the motor , 8600 to 11,000 at 1000 per second for first gear tune , 700 per second for 2nd gear tune and 300 for the top of high gear when it lays on the convertor.

Your fairly far off of understanding the concept, the time it takes to turn a roller and the corresponding hp is not anywhere close to reality of an engine dyno. I know that 1000 rpm’s per second is close to unachievable in a diesel with any kind of appreciable power.

There is a lot of manipulation of the way chassis dyno’s put out data, on paper. A spike be made to look like a big curve if you put hp on the side and rpms on the bottom, put time on the bottom and mph on the side and you will see most are extreme spikes. The dyno will read the spike up and down and average making it look like your sheet.

Anyone one that had spent any time on engine dyno, will understand reality.

Wheel speed yo!!!

LOL Better?

Greg I RUN the exact same sweeps you can on the engine dyno, I can set the sweep rpm/s just the same. Engine dyno vs chassis on that point is a dead end.

In fact I'd show even MORE "rev gain" on a engine dyno as the chasis dyno is not reading the inertia and associated loss of the drive train/wheels/rubber.

**** that means my 2200hp blown 565 alky motor would have made more hp at 250rpms per second. Crap

Why would you assume he does not also dyno in the engine operating range???

On a maximum effort race motor that is tunes to run in a power band, its tunes to run at a certain power band . If you pull it below that on a gas motor, you will need new pistons.


This is not on motors that have little or no rules. When you are restricted to CID to weight, then 16.8 to 1 gas motors will not run down low.
I have many many years of doing this, and a chassis dyno is good for tuning, and its good sport, but it will never be the tool to use on maximum effort race programs.

I’ll tell you now, any of the diesel engines in existents now will more than likely not light a charger and accelerate at a true 1000 rpms per second rate.
A chassis dyno has many tool it its software to extrapolate and print hp, doesn’t mean its always real

It would print a larger number on the dyno, but if that is not the way the motor is run then what good is that. I don’t dyno to make numbers to brag on, we use the dyno to find small amounts of power a few hp at a time. Start making 2.6 hp per cube on gasoline without a blower, turbo or nitrous and you will understand. The latest 500 inch Pro Stock engine programs make over 3 per cube

You're so damn arrogant. His needs are clearly different than yours, he needs his stuff to actually run.
 
i guess these guys dont know what their doing on a chassis dyno.

i agree its just a tool but for you to say that you would gain more hp on a ENGINE dyno by doing a lower rpm per second sweep is just crazy.

you are an an idiot greg if you think your the only one that has messed with that kind of chit. we have a a 263 ci small block that makes 1231 with a whipple on gasoline for land speed stuff. i know dynos, and what they are used for. an engine dyno is just that, it tells you what the engine it self does. a chassis dyno does just that, tells you what the engine does coupled behind a bunch of moving parts. are they both just tuning tools? absolutely but dont set here and try to act like your 100X smarter than everyone else on here. i have been doing this gasoline chit along time as well.
 
Are we going to see a whole string of pictures of Greg standing next to various things now?
