So I photoshopped the Akro posted dyno sheet adding the high rpm's where the throttles close down. I think the numbers look feasable.

My calculations must be out or my formulas for working out HP, Torque at RPM based on the graph. What do you mean you photoshopped it?

Rock.

He means, it's what he hopes the H2 will do after ECU restrictions are removed. Yes, the graph is not feasible, but one can always dream.

... I just assumed everyone knows what "Photoshopped" means. Like as in Kardashian or playboy. That's why it was the first word in the thread.

It is not a formula or a calculation ...but just a creative rendition of what something could look like in an imaginative world.

I think if you look at Dons throttle position table you see the throttles are closing above 10.5k. So if we assume they stay open 100% all the way up 13k and also consider the statement that centrifugal SC works better the faster they spin we should be able to project the relatively linear power curves out using the Akropovic dyno chart as a real world baseline. ...Is it really just Photoshop and wishful thinking? Or a set of reasonable deductions and guesstimations?

Who needs formulas, science and correlation between torque, engine speed and HP when we have photoshop and our imaginations. :)

Did sir Isaac Newton discover gravity through calculation? or something else like imagination or intuition. Maybe today we would call him a back yard mechanic with math skillz.

Imagination allows us to dream up big Ideas only then does the math, science and calculation allow us to achieve it. But none of this really applies to this simple premise does it.

We have an actual dyno chart with purported good data showing a very linear power curve. We also have an actual throttle position table showing the throttles close down in a certain RPM range which also just happens to coincide with a downturn in the chart. It doesn't take a rocket scientist to figure out if you get back the lost throttle opening the power curve will continue upward much further along the same general vector.

I'm normally a very tongue in cheek kind of guy and this was originally a post to alleviate boredom and tweak some discussion so if you don't agree that's fine but I don't believe you've posted any results of your scientific calculations? And it sounds from your response you're sitting on a treasure trove of technical knowledge there I'm sure we'd all love to hear about? or would you just rather comment on how dumb someone else sounds like H2R does/did?

The glass remains 2/3's full. :)

In the interest of alleviating boredom and tweaking some discussion here is a graph of three dyno runs Don did today on a something between an H2 and H2R that he sent me. Don is in transit and I'm sure he will do a new post with all the details when he gets back. As I understand it all three runs where done back to back with the same mechanical configuration. The only difference was the ECU flash. (This is rear wheel hp)

Just to be clear because of the thread topic THIS IS NOT PHOTOSHOPPED.

@Kawiguy-Hope ya weren't thinking I actually DIDN'T 'like'it...I know it's just fun speculation.I gave a kiss at the end...I'm kinda tongue in cheek myself;)However...I definitely LIKE the one Ridgeracer posted...Good Job Don and Ridge.

So basically with a H2R exhaust or fuel system the bike will make about 240hp...... wheres H2R to complain now?

Keep up the great work Guhl and Ridge Racer, you guys are awesome!!!!

I am readiing between the lines here...but the blue and red lines may be an H2 and the green an R?

Do we know about fuel pump limitations yet?

Oh, and thanks RidgeRacer...good stuff...no more speculation!

I would like to apologize to everyone for my crappy Photoshop job. I really like the real dyno chart posted much better!!! Thanks so much now i'm not bored!!!

Im guessing the blue run is an H2 and an aftermarket pipe? clearly the power still falls off due to throttles closing down. Guessing other runs are with the throttles staying open all the way up? Better than I expected...

Whatever the tweaks are this is serious improvement. 237rwhp is a good start for me :)

Wasn't trying to make you sound dumb at all. If it came across that way, apologies brother.

Was trying to work out what you meant by photoshopped and the extent of what was real and what was embellished as I didn't see the original you played with in photoshop. (So tried to reverse engineer the numbers myself from your graph).

I thank Newton and follow-up physicists to be in that position but Einstein would probably muddy the waters further on how we talk about the H2's speed and acceleration (all relative LOL) - even with our formulas (set in stone on how torque, HP and engine speed are all related - that we can't imagine and change) :)

Keep the glass full man!

Rock.

...like the sound of that brother. I like a forum where there's a place for anybody to speak at many levels of knowledge without snobbery where we all contribute/benefit but sometimes I overreact.There's no icon for Fistbump-Explosion or it would be here. ;)
From the looks of the REAL sheet posted looks like the glass is surely full :)
