My friend raised a question of using 100% methanol along with a VTA BOV.
At 20+ psi, there is no chance for teh methanol running downstream. But when the alky injection running at full blast at WOT, with a sudden close of the throttle, the alky and air are both shut off from entering the throttle body. The remaining air will be blew off from the VTA BOV... along with some methanol Does it spell ENGINE FIRE??

What are your thoughts on this, Mr. Buschur? Al? Shiv?

Water although do not have any octane rating but it has a positive effective octane influence on any fuel, not so easy to quantify. Methanol does have a direct influence on octane rating and can be calculated. To further compare the two beyond mentioned is almost impossible. As regarding tuning potential, they are quite similar, the result will be resting on the person's preference and ability, it is a very personal affair. In the days where competing businesses meet in a public forum, exhibiting a good impression to potential custom is important. Because if this pre-condition, sometimes leads to unnecessary heated discussion that leads to nowhere and the meaning of a discussion is lost - giving example and dyno chart is meaningless - once you grasp the basics of the two concepts, you cannot go wrong. History has always shown the injected ratio as 50/50 - no winner or losers there...

What ever you do don't place the jet before the bov !

""Richard: Can you achieve the capability of pure MeOH injection with just water alone?""

No contest, water cannot compete with alcohol when the purpose is for supplimenting the pump fuel's octane rating. It is like comparing injecting gasoline against injecting methanol or injecting methanol and nitromethane.

The exact distance between the BOV and the alcohol jet is 19"

I have never seen ANY plume of methanol release from the bov to date what so ever

I have never had any isssue what so ever

Of course - with all evos I would always recomend a re-circ BOV with the stock ecu and maf sesnsor - especially when using alcohol

However - I personally have not seen any problems and my car has been to 9 races this year and countless hours on the dyno where air flow is minimal

and again, please compare apples to apples. Most guys here running injection kit have their stock turbos. Anyone running your same setup will get the same result...maybe better. Timing/Fuel/Boost, thats all there is!

BTW - I guess the same theory would apply to fogger NOS systems which squirt fuel and NOS into the upper fmic near the TB - mine does not shoot out the bov either - no problems that I have heard
