Re: Lets talk pulleys again (or is it pullies?)
I have run and tested all combinations including stacked 178.
I autocross and enjoy the 185 for the bottom end. I would recommend that a streeter, go 185 get the bottom end gains. When I developed the super cooler and pulley saver design for Rob, I was running the 178. ITs a good pulley too, and if your doing lots of high speed driving Id consider it too for the reasons stated above.
I believe that the eurocharged 185 that I tested and run ( got 354 hp at Carlisle this summer) is working because I spent hours making sure it was on right. I chased all the threads, used moly antiseeze, and verified the belt alignment before cranking it up. On any given weekend Iam shreading my tires turning near 6000 for 45 - 60 seconds at a crack, without any big pieces falling off. Autocrossing with the Yaw sensor and T/C switched off.
Some like this some like that, there is not enough difference to really make a case for one over the other in my mind. I currently have the 178 on the shelf and have no reason to get rid of it or install it.
Me for the street, down low the 185 has the go.
Enjoy the HARVEST MOON TONIGHT. WOODY
