You may want to PM Juan from The Pettit SC thread as he has dynoed some with w/m on and off with different jets on a twin screw set up. He did not loose any power--with a total of 175cc jets. @ nozzle set up one pre blower (and a/w intercooler) and one post blower.
Folks may not realize that all methanol sources may not equally be as good.

It is actually 160cc (100cc pre blower and 60cc post blower) 50/50 mix of VP M-5. Anything higher of 160cc will bring rwhp down on my set up. Remember that every particular set up will yield different results. DO NOT spray prior turbo or the mist will ruin the turbo blades.

Would it be possible to install a generic IAT sensor post blower/turbo and hook up the two wires from the present MAF/AIT location?

If so, what IAT sensor will work best?

What benefits can be attain given that the ECU will be registering actual IAT specially when boosting/spraying?

That would be the Charles R. Hill Gas Law #1, not to be confused with the Charles R. Hill Post-Taco/Burrito fest gas law #2. In the latter case, a hose is run directly from the rectum to the UIM; however fluctating pressures and inconsistent delivery have been proving to be problems...

We in Az do have some "crap gas" and this just proves it..

Suspect about that dyno chart. :suspect:

I removed the pre-blower injection, all my alky comes after the inter-cooler to avoid the creeping red crud buildup.....


I can tell, by the way the car pulls, if I am adding nitromethane or just 50/50 water methanol.

I need to dyno with each mix...

Too much water (or any liquid) will quench the combustion...

absolutely do not use M-3 or M-5 for WI, M-5 especially = fail

^You're lucky that hundred shot of NOS 50/50 Water/M-5 didn't blow the welds on the intake!
