What is expected rpm increase when going from rival e1 to et 18 lb wheel?
Any info would be appreciated.
That's supposed to say riva not rival. Damn auto correct on these phones.

maybe 200-300 rpm that is a additional 2-3psi of boost

in our extreme hot weather with my E1 wheel im only seeing 12-13 pound of boost at 7800-7900 rpm
i dont think you will gain a lot with ET18

We are seeing 20 lbs of boost with a et18 and never seen anything over 16 with a e1

regarding your PSI levels.... these superchargers are centrifugal. The more RPM your engine turns the more boost your supercharger will make.
The reason you only see 12-13 psi is because you are only turning 7900 RPM.
Those turning 8700 RPM with an E1 see 16-17 psi boost pressure.

what bothers me that with my E1 wheel i cant turn big props like the 160mm 15/23
i tried this prop last summer with my stock pump
and i could only turn 7000 RPM
i just dont get it !!!
one of my friends he have an RXP 255 model 2009
he have XX wheel with its package
the XX generate 13 to 15 pound's of boost
his using 15/22 solas prop , and his RPM's are 8200
this is why im going for H1 wheel
