I have been running Aquamists 2D system with race pump and 1mm jet in my RX7 for a while now. I swapped race pump for new Shurflo, now have .8mm jet in turbo scroll, plus .7mm & 1mm jets between intercooler and throttle body.

The flow is controlled by fuel injector duty and equates to about 1250cc of 50/50water/meths per minute based on 100% duty.

I am running Microtech ECU, Bosch coils, NGK 10EGV's and 850/1680cc injectors. No sign of bogging down, but I do get a small amount of blow by water in my catch bottle. So changing oil at every 1500 miles.

 

nice!

How does the in-turbine injection work for you? How is the staging between the two locations setup? (do they come on together?)

 

I can't give any comparisons on my setup as opposed to in front of compressor wheel, but I am very happy. Jet is installed at earliest possible point of scroll.

At present all three jets cut in at 2psi above 3000 rpms with flow matched to injector duty.
