re: Looking for Timmy c lower pulley
Fresh from the anodizer
I've had one on my car for well over a year and I love it. 7.5" diameter is 27.5% larger than stock. It is sized for the stock upper pulley and that's what I recommend. I have bolt on upper pulleys in the stock size for people who have my 2.4" upper.
Installation is very easy too. No need to replace the entire balancer. Just bolt this to the supercharger portion of the stock balancer. Supporting mods required are injectors, tune, and intake.
I like this idea much better than the upper. If I decide to keep my car any longer, have had it parked since picking it up from the dealer after my bent valve fiasco, I might have to go with this, This setup won't go walking on the shaft like the upper did.
