Texas Two Step Taco

Yes the C12 in the mason jar was from the two gallons i mixed back in June.

I am astonished at what I am seeing BB do. My pockets are not that deep to accomplish such resolve. He is doing things others have said are not possible and am pretty sure he has 10,000 hours just on the dyno.

Curious what happens to the Taco on the dyno with fresh fuel.

Then there are the secrets that John has concerning the Bultaco that nobody else knows. Follow the torque!

It's all torque.. That's what provides the "go force". HP is just a number.

As for BB. If he wants to stay fastest in the whole world, he has to stay ahead of the pack and that takes cubic dedication. There are others out there with almost as much time/money/dedication, so he has to keep pushing that envelope to stay ahead. The rest of us are just playing in the kids sandbox and having a good ole time watching the experts and learning something as we tag along.
 
No, I use Shell M with methanol and also with gas. I was using an ester with the air cooled engine on gas but had piston scuffing issues because the rear (thrust) wall consisted mainly of intake port. Switching to the castor blend eliminated the scuffing completely and gave a small hp increase as a bonus. The Shell M is easily available here as many of the kart guys use it.

I feel confident suggesting the Elf 909 - despite not using it personally - simply because I know of people that have made over 400hp/liter that use it and recommend it highly. If Shell M became hard to get here I'd have no qualms about switching to 909.

It is all the rage on a Kiwi web site. The same one that Frits hangs out on. I can’t find out if it is used with Methanol, it says leaded and unleaded fuel. The Elf web site says it is a castor/synthetic blend.

So the full synthetic Elf 976 was used in the Motogp two strokes. The best for the best.

I have two liters in my basket at the moment. Do you think it would mix with methanol since it is a castor blend?
Klotz BeNOL and Maxima 927 both mix with methanol.

I guess what I am asking is what happened in the combustion process that gave us more O2 with the compromised fuel? Did it come from the water insuspension in the compromised fuel? And how did we make so much power with the compromised fuel by jetting up?

BMW made a water injection system that injected water into the intake and it evaporates and cools the process

Could the water in the fuel be doing the same thing?

Going back to the dyno today to test fresh fuel and oil. Will test the Klotz BeNOL 20:1 in c12 and the Maxima Castor 927 20:1 in C12. Will also take the compromised fuel to test if we have a surprise of less power. Temps will be around 55 at noon and 57 at 1pm.

Teazer said this earlier: Bill is correct that lambda results can be misleading. As John points out, give the motor what it wants for max power and keep that record as a baseline. Lambda isn't actually what is read by the O2 sensor. It supposedly measures unburned oxygen, so a high O2 number usually means too little fuel and that's how we interpret it, but it doesn't tell us much more than that. All it really tells us is how much oxygen is in the exhaust - all other things being equal. So if the mix is lean and still burning in the pipe, it could be showing low O2 levels by the time that gas reaches the sensor.

It's just an O2 reading, nothing more or less, and it isn't a reliable indicator of mixture with a two stroke engine and can indicate all sorts of things besides mixture strength.

Ask yourself this: Why am I doing all this tuning work? Is it to produce the maximum possible power or is it to reach some magic number from an O2 sensor? If the goal is performance then the best plan would be to remove the sensor (or ignore it) and follow the suggestions of the torque gauge. The last thing you need is the O2 distracting you - the torque gauge speaks the truth, the O2 just second guesses it with vague suggestions and half-assed theories. Yeah, I know, I sound like a broken record...

No, the BMW is irrelevant to the N/A Bul engine.
 
We mixed new fuel C12 with the BeNOL and it immediately separated. The bike wouldn’t even run. We the ran the maxima 927 castor for two runs.

We are jetting up Q16 40:1 Redline synthetic we are running lean with a 270 jet going to a 300

Yeah, they are no good above 11,000 rpm. What's up with the tacho reading. Need a different pickup or too much noise?
 
We were on the rev limiter big time. It was pulling hard. Will post video later. Must be noise engine speed was 9k. Tire was also slipping

Well we pulled out a chunk of Aluminium and worked all night to fix the taco clutch

Bb added water to the fresh c12 and Klotz BeNOL after it had separated to see what would happen. The specific gravity of VPc12 is .71 at 60 degrees. Klotz BeNOL specific gravity must be between water and C12.
