What size is your fuel tank and how long does it last with the 52s?

2020 ET1107 about 20 hours, ET crank.
200psi
50/50 110-91 octane
Carbs: Dual 49mm full specs, oem pumps(for now)
Main jet: 120
Pilot jet: 137.5
Popoff: 26psi 70 return jet.
Needle and seat: 1.8
Low screw: 3/4
High screw: 1/2
Pump: Skat-trak 155 setback, pee pee trim.
Prop: 6/14 longblade, it’s to loose.
Pipe: PFP dry, rrp box.
Ignition: Stock charging, 3mm advanced, MSD enhancer, jetnetics flywheel.
Hull: Rickter XFR glass

Messed with larger or no Return jets but always seems to run out of fuel on combos.
Full specs always seem to dribble a little to a lot.

Rips and can somewhat combo, but can still has more potential to be unlocked.


@SmittySX do you have a 1107 with a formula that hits? Or asking for a friend

IMHO your nuts running that on an enhancer. You’re leaving tons of power on the table and it’s risky given how much timing they run in the upper RPMs

6/14 that is almost a sub 800 cc prop you need too pitch up

Have any of you guys had your 1107 cylinder ported?

 

[Jcary85]

Have any of you guys had your 1107 cylinder ported?

Ported how? Widening the exhaust port? Changing port timing? Art has these things pretty well dialed in. He did mention he can raise the exhaust port slightly if you want more of a race motor. I don’t think there’s much gain to be had by screwing with his porting (I did ask him about this back when I ordered my 1107 - was curious if I could pay more for some secret sauce extra porting but it sounded like there wasn’t much left on the table). Do you just mean smoothing out the port work a bit?
