Question Re: Nozzle spray angle...

I'm now running the smaller 75dia pulley on the s/c and using 50/50 w/w
methanol mix. I was out for a drive this afternoon and logged a short pull
in second gear that showed 195kPa @ 6000rpm. So with another 1800rpm
available, I think that 200kPa should be possible

The MAT and s/c discharge temps are quite a bit higher now with the 75mm
pulley. I can see as high as 95 MATand 115 degC s/c discharge cruising out
of boost at highway speeds (no injection). So I don't mind running a bit on
the rich side.

Car still runs very rich at WOT (into the 10's) and while I am dialling back
the gas to bring the AFR closer to 12:1 I am wondering if maybe I should go
back to the 0.5 nozzle I was using previously (0.6 currently fitted) ? Is there
any way for me to judge if I am injecting too much mix ?

Cheers... jondee86
