Methanol nozzle pre bov?

[Hiitman]

I was reading up on the different locations for installing a nozzle and why you should/shouldn't put it in X location. Apparently, the most ideal spot is directly after the intercooler. This gives the methanol the max amount of time to atomize and cool the intake charge. What I was wondering was, would this damage the bov at all? Lemme know what you guys think.

Won't you be sneezing a mixture of air and fuel out the BOV into a hot engine bay at that point? Sounds dangerous to me. Even if it's back into the intake, I don't think it's something I would do. I'm sure other people might to it though.

When people say after the intercooler, they are just implying obviously dont put it before the intercooler.

The ideal spot would be closest to the TB.

I think he's referring to the alcohol mixed with the air that would come out of the BOV. Well to answer that it shouldn't. When you let out of the gas and hit vacuum during a shift the alky shuts off and only comes back on once the boost is back and the BOV is closed.

I'm running one M10 nozzle right at the bend in the TB elbow ( i changed today from an M7 ) But i am going to put one in the UICP where it starts to go down through the passenger fender to where the stock side mount was. This would be pre BOV, but i doubt anything bad is going to happen. I can't wait to try the 2 huge nozzles and no intercooler at all. Say hello to faster spools!! (in theory anyway)

As for the slight bits of alcohol that might make it out the BOV or get on it. The alcohol will evaporate in the hot engine bay too fast to do anything, and the water mixed with it will help it from getting lit off by heat, since that's what he whole system is designed to help do and that's keep the temps and enough water vapor in the system to avoid pre-ignition, which would be when the fuel/air mix lights from hot spots in the motor instead of and before the spark happens.

What I was really wondering was if it will be destructive at all to have small amounts of methanol passing through the bov.

No you shouldn't have any problems

I disagree, the ideal spot is not closest to the TB. Doing this does not allow for the maximum atomization of the methanol. I better spot would be right after the blow off valve so that the mixture will not blow out, but still have the maximum time to atomize.

 

[Hiitman]

Wouldn't it only blow out between shifts?

 

[turboglenn]

although after the BOV would be better remember what i said in my first post, when you let out of the gas, the meth shuts off, then under boost it comes back on...so what dcome sout the BOV will be very little if any, don't worry about it!

That's where mine is......Only because that was the easiest place to drill and tap for the nozzle.

If your BOV was mounted before your IC or on your IC endtank on the hotside.(like the fullrace style backdoor), you could mount your nozzle directly after your IC cold side with no worries of the mixture 'blowing out' though your BOV.

This is what i plan to do.. sorta. Im not going to put my BOV in the conventional spot 12" before the TB or so, i will put it before the IC under the bumper.

Assuming you're recirculating, and that the methanol doesn't completely vaporize, a mist of liquid would be similar to sandblasting the compressor wheel. Although very little would likely make it that far, it would be more of a concern than the effects on the BOV itself.

Sorry I forgot to mention that I'm not recirculating. That is a good point though.
