whereto inject Alky on HA car?

Took a little to find it but here you go Brad.:biggrin:

Well the debate continues.:biggrin: The TB community is a firm believer in putting the alky after the turbo but I will point out that the original HA cars run it before the turbo. I've done a lot of research on it myself and all of the data says that putting the nozzle 12 inches before the turbo is the best location for atomization of the alky. A fine stream properly shot at the center of the inducer wheel won't "erode" the inducer wheel, like is clamed frequently, and cools the charge as it's being compressed so it's a win-win.:biggrin:

I must agree with this one though experience. My best results have been between the throttlebody and MAF. I'm thinking it has to do with enough time to atomize and cool the mixture.

Mine seems to work well. I've read that cooling the air in the compressor would increase its efficency quite a bit. I have it about 4" upstream of the throttlebody. The only ones who may have problems are the cold air's which could collect liquid in their intercoolers.

Since the Alky is so close to the cylinders it has less time to dissipate which is probably why you're bogging, but we need WAY more info before we come to that conclusion, so.....

1) What size Nozzle are you using, the M15?
2) What psi is the kit activating, 7psi?
3) Where is the Initial Knob time wise, example, 11am?
4) What is your Gain Knob set to, usually 6 for the new kits?
5) Is the chip for Alky?
6) What is the AF/R or Millivolts during the bog?

Pre-Turbo Injection is old news here, I already proved years ago the 1psi compressor map gain, that's the reason you do it, not for lower MAT temps = Post-Turbo.
