air - fuel mixture when running track days and H2O tuning?

[d15b7]

thank you very much for the reply!

you are absolutely right; i was out tuning last night, up and down rt 273 with the wideband and my HKS Super AFR.....

i leaned it out to a fairly steady 11.3 to 11.5 AFR from 4000 to 7000 (without the water). feels super strong now; really strong.

with the water engaged, it definitely feels "softer"; doesn't pull nearly as aggressively. that nozzle is too big (the 6.39 gph nozzle, which is rated that at 40 psi, and i am running a 100 psi pump).

this morning, i ordered two more nozzles; a 4.4 and a 3.1. will try those out soon!

thanx again!
