Results of my Direct Port Water / Meth Injection ~VIDEO~

[Carmen]

Tested out the setup today to see spray pattern and reaction time.

I am pretty pleased .. now we just need to have a motor to put it on.

What do you guys think?

Good spray distribution....diggin it!

Just was looking into direct port. I read arguments that said you should just spray after the turbo and farther from the intake ports to maximize the time for intake air temperatures to decrease. I think I still like the plain and simple one nozzle near the throttle body.

Thoughts?

I went this route as I have a charge cooler core directly before the throttles. This is the only way you can guarantee that each cylinder is getting an equal amount of water/meth or straight meth if that is what you choose to do.

If I had it setup before the core it could puddle inside the intake or only a few cylinders would get it.

If you are going through a single TB, this becomes less of an issue, but there will always be benefit by going with this configuration as there is no question of what is going where.

So you have a water to air intercooler system in the IM?

I've been thinking of machining an aluminum spacers for 1 and/or 2 nozzle to be installed between the TB and the IM. What do you think of this idea? Mainly I've seen nozzles just installed into the throttle body tube (pre TB).

Yes. The e46 M3 using individual TBs, so my water to air charge cooler is directly in front of them.

As to your setup, you would just need to run a check valve so the system doesn't leak while the motor is under vacuum (you would be sucking in fluid all the time). You are still relying on the manifold to distribute the meth.

Everything looks great an even! I can't wait to see this in a motor!
