I have a meth plate behind the TB. The recommended place is a bend within 12" of the front of the TB. That will give you good flash results and still have a good meth mix by the time it hits the cylinder. I went with the plate because of safety reasons. Since the hemi throttlebody shaft isn't sealed, anything you spray in front of the tb will enter the shaft motor. Snow Performance talked with me about this awhile back and entertained a plate system as well but the cost was too much for their basic kit. I have only seen two throttlebody failures due to gas in the shaft motor so it's not a common thing.

Okay...This setup is with a Paxton centrifical blower and a Vortech intercooler. The intercooler is mounted in front of my throttle body. I then have a 12" piece of piping, with one 90 degree bend in it, where my SnowPerformance w/m injectors are mounted, which then attach to the output side of my blower. What my question is, is should I inject my w/m through the water/air intercooler, or after it behind the throttle body?

Have you talked to GSM to see if they've done any tests of spraying a wet mix through the i/c?
My thought would be to run it like you have it (through the i/c). With the smt6/injector setup you can pulse your fuel to a lower a/f. It's amazing what an 11.2 a/f will do with cooling characterstics. Make some short burst runs to get EGT baselines. Then introduce your meth injection and see what your EGT's do. You may have to back off the fuel a little when you do this. After you make some runs, pull the i/c and look for puddling. If your EGT's stay in a comfortable zone and you're not puddling the i/c run it for a while and recheck.

With GSM's fantasitc customer service lately, it would take another 7 mo. to get an answer. lol Fever, I love your injector plate. We have a modified throttle body spacer we could use to place the nozzle's behind the throttle body. I'm just looking for the extra intercooling effect by injecting the w/m through the intercooler and if anyone has done this and what I might expect with the good or the bad.
