Installed the RR crank pulley over a week ago. Been doing dragy testing since then. Also just finished putting on the RR underdrive water pump pulley.
I definitely love this modification. Very noticeable acceleration difference when I'm driving normal around my neighborhood area. Feels slightly quicker when punching it in 2nd and 3rd gear WOT.

Just ordered the pulley combo from R&R, and new tensioner/idler/belt kit from Rock Auto. Does anyone know the torque spec's for the tensioner, idler, W/P, and scavenge pump pulley's ?
And, Thank you in advance.

I am still wondering if there is any possibility of overheating with the underdrive water pump pulley sitting here in hot weather California in heavy traffic. @RRRacing
Rafi did not experience any overheating in the hot Summer months. I don't believe the change isn't big enough to cause a problem on the low end.
