injector location
I've been installing an AEM system on my stock RX-7. I have not yet attempted to drill/tap anywhere for the injector. I know I'm going to put it somewhere after the intercooler. Is there an optimal place? I was thinking that the more space between the injection point and the UIM would allow more time for the cooling effect. Just looking for a tip otherwise I will just stick closer to the intercooler outlet.

I asked a similar question in my thread here.

This was Howard's response which is what I followed as closely as possible. I ended up mounting in the TB elbow since I could tap it and screw in the injector. I had to concede a bit and mount it a couple of inches closer to the TB than I would have ideally liked, but it helped with line routing and general ease of use by a bunch.

one nozzle:
best placement at 4:30 looking at the upstream opening of the elbow.
that way you bias against the 90 degree turn and bias toward the upper secondary butterflies.
two nozzles:
3 oclock and 6 oclock
location:
either in the silicone coupler just in front of the elbow or in the first 2 longitudinal
inches from the upstream start of the elbow.

So would you guys recommend getting the Greddy elbow w/flange if you were going to buy an elbow anyway? This would be good for a one injector set up.
It seems to be better in some way than mounting it in the silicon coupler before the elbow.
But I would in no way suggest anything other than what HC says, he knows his ****

I'm a noob when it comes to AI so all the info I get is from reading HC's threads. He has his injector location post-IC before the elbow.
Is there a pre-turbo location vs elbow location thread you fellows can direct me towards? (dont mean to thread jack)
