ET1107 with 155mm OEM pump, What impeller?

[shmity1]

Best bottom end.
Who is running similar size motor or same setup and what impeller are you running?
Impros said 10/16 E75.
What cone do you have?
What is the nozzle bored to?

Thanks

What hull do you ride?
What pipe, what ignition, and what compression. A lot of variables. Your engine builder should be the first guy to give you a baseline for impeller and pump tuning.

I'm putting a 1107 in my phantom starting with a skat 10/17 thinblade cutback.
Running a OEM pump stator
And I'll be starting tuning with a stock bore reduction nozzle.
But I'm not on the water yet so not really much help.

ET mentioned the 9/17, I am starting with a 10/16.
Will let you know when I get it on the water.

I run a 11/17 nozzle bored to 91mm it's linear power still plenty of low end if you just want bottom end I'd go with a 8/14 or 9/15

Are you running a thinblade cutback, or just straight up 11/17?

I saw someone on here running a 6/12 on a OE 155....

Oops nevermind that was a mild 7xx set up...
