i have installed 3 of them already in other peoples boats

speedy went 78.7 off the trailer this morn at the same location with the s3 wheel and stock ecu



so i am thinking s3 wheel, waterbox(coming soon), hmmm 79 stock ecu

wow

Wow! Good numbers ... once you have the impeller pitch/trailing edge just right and running the right nozzle size, you will be flying (you are already flying actually). What is Speedy's current setup, impeller and nozzle size?

he has the 15/20r untouched with the 81 nozzle

s3 wheel
rear air
stock ecu
stock waterbox

Jeepers ... Dan (RXP'n in MI) gained .7 mph going from an 81 to an 80mm nozzle ring I think ... if your rpms are over 8100, you may want to try an 80mm ring. I think 79 is within reach ... the exactly right impeller and nozzle ring combo can really help get the last few mph ...

[GTGRXP]

What IC is he (or you) running with that setup?

I'm about to be running close that setup and am trying to figure some benchmarks as to what I'll be running...

[DIGGS]

i still have the untouched 15/20 in mine with the stock nozzle

my nozzle setup will be here next week



speedy is turning solid 8100 with the 82 ring in the heat and pretty solid 8100 with the 81 ring in the morning time and or cooler water


i think in the fall with the 80 nozzle he will get 79

we will see

[DIGGS]

both of us have the xs i/c

we both have stock ecu's

he has the riva rear air i have a diy rear air(4 inch)

i have the stock exhaust (res removed) and he has the riva thru hull with stock waterbox


i have skegs he does not

[speedy]

Vern I plan on getting an 80 and 80.5 ring for the upcoming cooler months and hopefully see a 79. Did you notice much improvement in heat soak with the 158thermo?
