Impeller pitch for RXT
2008 rxt. riva s3 charger, 3" air intake, 42 lb injectors.
Stock prop was on limiter a bit when spring cool weather.
Put in my 13/18 and now that its hot, I only get 7940-7980 rpms.
I have a 14/17 as well. Do you think I should just remove a
little from trailing edge of 13/18
OR add a little to the 14/17
or do you thing the 14/17 will give me about 200 rpms over 13/18 ??
Speed is 67.4 with 13/18 on cool morning at 8000 rpm. (cant get that rpm
anymore with hotter weather).

Figured I'd error on the rich side with the S3 sc housing/wheel with the 42's...
Had the 42's and S3 here anyways. Also, had the 3" riva air intake too.. So
used what I had here.
So, do you think that there is "?" rpms difference between the
14/17 and the 13/18 ???? 100, 200, ????
