Cool thread!
I have chosen water injection over an intercooler on my miata/mx5. I have the jackson racing SC on a mk2 1999 1.6 (yup we got one in the uk)
Ive just had it dyno'd for a 'before and after WI' comparison.
I got 170.2 bhp and 135lb/ft torque @ 7psi with no intercooler. AFR 10.5! Dumping like mad! (flywheel HP)
I'm having it dyno'd again soon but need to fine tune the water injection. I didnt go in through the port in the JRSC throttle body as the thread was too deep for the AM nozzle - would have affected the spray pattern. I went in a couple of inches to the right of this spot. Nice and flush!
I'll get some graphs on here if anyone is still interested? It feels like its making no more power on just water. I'm going to lean up to about 11.5 and see how far I can knock back the JR BTC then maybe even buy the CAS bracket and advance a bit. I'm at 10 BTDC now would like to take it up to 14 BTDC or maybe even higher. Need to find more info on Methanol / additives.
Great Forum!!
