Guys with NEW RR SCer impeller. Questions!
Hey, Guys do we use our stock washer and nut to install the impeller and how do yall like it with Stock ECU and 42lb injecters?
Other input would be great aswell. I just got it today and I am installing it into my other SCer houseing and didn't know if the washer and nut were just the stock ones and not like my RIVA Vortec nut.

if you are running a stage II plus the RR SC I would run the 42 LB injectors I was running 12.7 at WOT with stock and now I run 11.9-12 WOT with the 42 LB injectors and my crusing numbers around 5500-6500 had my numbers around 14 with the stock so I just felt better with the 42 LB injectors

Scott, those AF numbers are what i saw with Careys ski as well. If you are running the external intercooler with the stock ECU then you will need the 42's.

42lb injectors here... but I also run the RR ECU. Lower air and water temps this last weekend produced 10 lbs of boost for a new high speed of 75.4 mph.
Now I need to get off my butt and install the skegs.

Jeff those numbers are awsome
I am at a best of 71.4 have you done any valve work I ask because I have not gone with the ECU until I beef up the valves as you seem not to have had any problems with your set up and I would like to be around 75
how many hours since you added the ECU ?
