no she doesn't but I will meet up with phil and let him show me the real vegas hehehehehehe this is a once in a life time chance by the sound of it

 

Watch out for the shovel in the desert meet.....

 

If it is on order from Snow it'll be another week or so as it is on back-order. Juan is supposed to be getting some, too.

 

Happy birthday Bastage

 

Thanks! I'm starting to get old; I found a gray hair on the back of my hand last week

 

Happy Birthay Bastage that wasn't a grey hair it was residue.lol

 

At 31 it was not yours

 

I KNEW someone would say something like that! It was definitely a gray hair, and it was definitely growing out of me.

 

Welcome to the club.................ole man! I got enough gray hair for all of us!

Seriously......Happy Birthday!

 

Gray hair, HA at 48 you can't have too many gray hairs, your just a teen ager in the scheme of things. How did your injury turn out?

 

I just got off the phone with Snow, they have no Nitromethane to make Nitro-Booster.
They say there is a worldwide shortage of Nitromethane.

VP Racing seems to have it.....
I think the RC car fuel is looking better by the minute.
Did the RC fuel really fall out of suspension?
It seemed the stuff worked, from the reports here.
(Am I just wishfully thinking?)

 

I have only one spot left on my body that doesnt have gray hair
olddragger

 

We Snow dealers have different information on the Nitro-Booster.

 

Can't remember your age - from the way you talk your a little on the high side of middle age so you deserve a few gray hairs. Dirt is the only thing older than me.

 

I will be 59 on 9/5-----sigh. BUT--I do now have the authority to pick on teenagers
1st retirement coming in 15 mos!
OD

 

I feel like my life is accelerating. The birth of my oldest kid feels like it just happened, only it's been almost 3.5 years. I need to stop blinking.

 

DON'T RETIRE, screw um - make them get rid of you - hang on and make their life as miserable as possible What will you do with yourself all day if you retire especially with kids still in college.

 

Yeah VP Fuels have it or you can do what I do is buy their M5 that comes with the Nitromethane and Lube premixed in with the methanol.

On a different note what is to lean on the A/F the Reason I ask is on my last data logs I got 12.5 and 12.8 with the meth on.

The reason they were different may be because I played with the meth mix.

The 12.5 run was 50/50 the 12.8 run was 30/70 30 water 70 M5

 

If you don't knock, 12.3:1 or so is pretty optimal.
However, one stutter from that meth pump and you could be walking home.
11.5:1 is a better target.

 

This sounds like our proof that nitromethane will lean out an A/F ratio.
As MM pointed out, the pump may stutter;

which cuts off the very stuff leaning the mixture.


The question now would be can the pump "over-pump" in a "reverse-stutter"?

 

No, its the other way around.
The reading is leaner because the water/meth/nitro is displacing fuel.
Remember the stochiometry of meth and nitro. Both carry their own oxygen into the fire.
Nitro will burn without oxidant.

You are reading an AFR based on a 14.7:1 stochiometry.
However, you have introduced two new fuels in unregulated amounts that have 6.7:1 and 1.7:1 stochiometric values.
Even though 12.5:1 is .85 λ for gasoline, its 1.8 λ for meth (very lean) and 7.4 λ for nitro (off-scale lean).

 

Well any one that wants to see my last EFI dude data log send me a PM with your email address and I'll send the file. If you don't have the EFI Dude software I can send the data over in .xls

 

here is a screen shot of my last data log with no meth 12.3 A/F
I think I am ok

 

How do you read that with no scale? Without a scale, that print is pretty meaningless.

Also, can't you expand just the loaded part of the run?

 

I'll do this without the math, the simple way:
Hey munche187, what was the A/F without the methanol/nitromethane mixture injected?
