If your running 21 psi and only looking to get a few more psi from it, a smaller nozzle can be used and possibly keep you in that 11.0 range. This would mean less dependance on the system and less consumption.
Our cars typically favor AFR's in the lower 11's with straight pump gas. Using injection.. straight methanol..as you introduce methanol, its stoich being lower, that target gets moved down. Rule of thumb is 10.8-11.0 on a single nozzle. And mid 10's on a twin. I have a customer who runs 9.6:1 AFR on pump gas and it runs low 5's in the 1/8. I personally run 10.5 target on mine using twin 15 gph nozzles. If I was tuning at a track I would start at 10.4-10.5 on a single make a pass and look at the MPH pickup between 1/8 and 1/4. Then pull fuel out to Lean it out and see if the MPH on both points increases. If so.. your on the right track. Same can be said of timing.. start at 18 degree's.. and work up till it doesn't MPH any more. A degree at a time.. Same with amount sprayed.. start on a greater amount and work on reducing how much is sprayed. So if you wanted to lean it out a touch.. you can bring down settings a little a time until you register a small amount of KR. Like .5-1 degree. Once your figure out what AFR it likes.. then move up on timing and see where that goes.. any KR.. add methanol "IF" the fueling is there. So if you saw 12.0 AFR and knock.. you would add fuel. This all takes patience and being able to be repetitive on the knowns like boost, timing, ambient temps, etc. In the end this is how to extract the most from any combination.
E85.. tune using lambda. Stoich on meth is 7:1, ethanol is 8.5:1, gasoline 14.7:1 When you mix them some wide band sensors are not too accurate.. so start rich and work up leaning on it.
Hope this helps
Dave, this calculator might help. http://www.wallaceracing.com/air-fuel-lambda.php
Now I'm more confused than ever with that. If I enter a gasoline value of 11.4 for example (my WOT value), the calculator says E85 equiv. is 7.57 !! How do I manage that? My WBO2 wont display numbers that low.
lambda tuning direct from the sensor?
So does that mean if I shoot for 11.4 on gas, that I should still shoot for 11.4 on E85?
No. The lambda value is what the sensor outputs so if you can find a sensor that reads accurate in that 8.5AFR range. Not sure what the lambda would be at that AFR.
As a tribute to him.. put it on and give it a whirl. Life is all about decisions.. some you make, some are made for you by others. You have a wealth of information on this particular website as to what to do and not to do with your car. Up to you really for the ultimate decision. Most of us posting on this thread have been there and done that sharing our wisdom. Typically post count lets you know how long someone has been around contributing.
Some may be good at paint and body, engine building, chassis setup, tuning.. as to meth.. my middle finger knows more about meth injection on a Buick than anyone I know.
PS.. that chip you have is a copy.. Red's chips don't look like that.
