Are we going to see a whole string of pictures of Greg standing next to various things now?

yup, the same 15 or so pictures he ALWAYS posts.

let me set the stage:

-Here is me at _____ running ______ SMOKE FREE. I was the first diesel to ever do this.

-Here I am on the first engine dyno in the history of the earth.

- Here I am with the first ever Race Program. Rev Gain was invented here.

What a motor makes is what it makes. If you pull it at a slower acceleration rate it will print a higher number. The application here is to pull the motor at the rate it’s going to go down the track. At that rate then you can tune to that set of perimeters and go faster.

Bullchit, without the motor in the car and actually testing and seeing first hand the rate of acceleration you are freaking guessing in the rate. If course you can get close with some calculations. So your saying you know 100% the rpm rise rate for every gear without even had the motor in the car? Lol no way. And I would love to see proof that a slower acceleration in a engine dyno will produce higher hp numbers, like 300 less like you claimed lol

AS MUCH as it pains me to side with Greg......:nail:

It will show more power the slower you let it accelerate.

When you sweep up, a fast sweep will show more the "heavy" components rotating and reciprocating inertia and the power it takes to accelerate them.

On the other side if you make a fast pull down sweep, those same heavy parts will "flywheel" and you will show more power, that is stored in this mass.
(Think weighted crank on the sled pullers).

In idea you would be best served on the dyno sweeping at a very similar rate as on the track.

granted i can see that and where you coming from but why sweep a diesel at or any engine for that mater at less than 500rpms per second when its WAY faster of an rpm rise going down the track? like we all said dynos are just tools but #1 you wont know the desired rpm rise without having the motor in the car and actually testing that. without knowing that, your engine dyno sweeps are just a guess. either way, saying a diesel will not run nor make power at close to 1000rpm per second is false
 
you look at data logs , and match the ramp rate to the observed accelaration rate [ame="http://www.youtube.com/watch?v=rKH2RWZdZhM&feature=related"]http://www.youtube.com/watch?v=rKH2RWZdZhM&feature=related[/ame]

Here is a dyno session I found of a C/ED motor on the dyno, notice that the motor is brought up to full throttle and wait for it to steady state then you see the test acceleration rate applied

Here is a data log that has the engine in first gear rev 1000 rpms in under 7ths of a second.

greg i fully understand how a dyno works and i can see how you could make more hp at a slower rpm rate but most setups are well more than 150 rpm per second rise. here is my OLD 406 at 7psi that did 1100, you can notice how low and long the sweep is.

1,210 rpm rise in 1.00 seconds real world data from an actual pass. RPM rise in 2nd gear. This is from a 10.52 pass at 6800 lbs and big heavy $hit in the engine.



Imagine what it would be if I wasn't loosing 40%:doh:


:hehe:

Maybe we should ask Dmitri.... :poke:


On a serious note seeing as I can't make out any of the numbers on the gif due to poor resolution... Are you locked before you engaged 2nd?

ohh I think I see now.. the marker line thing is where lockup occurred.

Lock up is the first dip in rpm before it shifts to 2nd. The marker is just a reference point and start of 2nd gear rpm rise. Also, the values in the left hand box are the values at the marker. The cursor on the rpms is at 1.0046 seconds after the marker and shows the value at the bottom of the screen.

no its a 454 Dmax all aluminum motor. already has a bruno and a 5 speed liberty

Priceless.....LOL

All this time we've been lead to believe the earth revolves around the sun when infact it revolves around Greg Hogue. :lolly:

^^^^ Well look above, Dockboy's data showing the impossible as well.
