Re: Nozzle spray angle...
Small update. Currently running on the 87mm dia pulley and making around
71-72kPa of boost while running very rich when getting into the new area
at the top of the map. Working on getting those tuned a bit better now.
My ECU can log in lambda but my WBO2 gauge can only indicate in AFR. So
to avoid confusing myself I shall continue working in AFR. Just drained the
water out of the tank and replaced it with 50/50 v/v methanol mix. So going
by your previous advice I shall continue to adjust the map to get the actual
recorded AFR as close as possible to my (conservative) target AFR's.
I shall probably look at installing the 75mm dia pulley in a few weeks, as
there was very little that required adjusting when I installed the 87mm dia
pulley in place of the 105mm dia. Once I have the 75mm dia pulley on the
engine I will look at getting the car on the dyne for some professional tuning
and to see if getting the ignition and fuel closer to optimum will help find a
bit more power and improve my gas mileage !!!

PS: Does a methanol and water mix always turn milky ?
