370....whatre you aiming for?

and 8psi is WAY to low to start injecting at...

 

I was aiming for 350, haha! No I think I can get 400 with an adrenaline HPOP. Y is 8 too low??? That's what snow recommended and it feels smooth, no quench, plus the dyno liked it!!!

 

the engine isnt working hard enough at 8psi to use the meth the way it should be used, if its on a dyno and even when pulling id set it at 20 or 25, you need the additional hp the meth will give you at higher rpm...higher rpm=higher boost=more hp.

 

do u understand that it starts injection 10% of the mix at 8# and gradually increases to 100% at 23# and up. so 8# is just fine especially in the lower gears of my zf6 cause i dont build much boost.

 

You wont get anything more than 340 or so on fuel out of stock injectors, no matter what you support them with, just not enough fuel. I'm suprised you got that much from just adding the water/meth on top of it.

 

I was thinking 360 with a setup that gets all it can on the stock injectors.

 

Show me a dyno sheet!

 

He!!, I don't have one Kris. I am just talking about what I have heard with stock injectors and all the other goodies. Theory if you will. They ought to be able to make that.

Or did you want to see my dyno sheet?

 

didn't know whos dyno sheet u wanted, but here's mine

 

thanks for the vid!

 

Thanks for the video.
It really helps me look forward to this weekend at the Dyno day in Oregon.

 

Wow...

 

I've got some questions and comments. Were there any differences in methanol or diesel fuel settings between RunFile_001 and RunFile_002 which gave an 11 HP difference or were these just back-to-back runs without changing anything? Were both runs made in 4th gear which I think is direct drive for your tranny? Doing a run in 5th gear vs 4th gear will typically give a higher maximum HP reading!

Did you ask the dyno operator what smoothing correction factor and atmospheric correction factor he used and why he chose the ones he did? Your chart indicates an SAE CF=5 for data smoothing which is the highest setting possible on a scale of 1 to 5. If you'd used a lower CF for data smoothing you would've gotten a higher maximum HP reading! I'm not saying this is a "real" HP increase but a dyno sheet with a higher maximum HP reading printed on it does give certain bragging rights!

Evidently no atmospheric CF was used to "adjust" your dyno results to SAE standard atmospheric conditions so that they can be compared on an "apples-to-apples" basis with other dyno runs? Since the temperature and barometric pressure (especially at different altitudes) makes a big difference in HP you need to know these factors to compare dyno results between different trucks and for the same truck from one dyno testing session to the next! The atmospheric CF predicts the HP that would be developed if the dyno run was done at sea level under standard pressure and temperature conditions.

If you remember what the weather conditions were you can "manually" adjust your results using the same equation that the Dynojet computer uses. Dynojet’s WinPEP (Performance Evaluation Program for Windows 95) software uses the SAE’s latest correction formula (June 1990) ...The formula used is: CF=(1.18)x{(29.22)/(Bdo)}x{(To+460)/(537)}-(0.18) ...Where: Bdo=Dry ambient absolute barometric pressure and To=Intake air temperature in degrees F.

 

I think the HP limitation with stock injectors is well summarized in the clip below...



...and note the part about ...It needs to be commanded with a longer pulse width, and it has to begin the injection cycle earlier. ...and the part... when timing is advanced too far combustion pressure soars!

So even with an upgraded HPOP the fuel flow with stock injectors is ultimately limited by excessive injection advance which means that you're compressing combusting fuel during the compression strokes and this extra pumping loss reduces the net FWHP and possibly blows a head gasket as well!

The above explains why methanol and nitrous oxide can give more HP because these methods fuel through the intake air supply and therefore bypass the timing limitation with stock injectors!

 

Those were back to back with NO change. He pulled in 6th gear cause he said diesels torque responds better in OD. As for the second part, my head almost exploded, haha. It was a nice day, mid 60's no humidity plus I live in nebraska so I don't think altitude is an issue.
