Want to hear some opinions on the new pulley from vrpspeed, would that be too much for daily driving, how will reliability be affected, and also what cooling mods should I consider for this?

Pretty sure that's equal to a 194mm crank pulley. Search 195 crank pulley e55

It's pretty big. You will need a lot of mods to run it.

Man this is gonna be interesting. Been wanting to go to a 168mm pulley with my 77 but I didn't wanna spin all my other components faster along with the s/c. Happy I held off

the ratio looks to be 2.2 which would make this equal to a 198mm crank pulley excited

Assuming a FBO E55, I wonder what sort of power gain could be expected going from a 77mm to this?

Again, assuming cooling is in check via trunk tank, KC and/or Meth. Full exhaust, injectors, 82mm TB, etc.

I would ask Phil (the owner and good guy) who is using the set-up, results, and what cooling mods they are running.

Flamer thrower ,and your also maxing out the stock blower and stressing your bearing and parts associated with it.

One of the first thoughts that came to mind.

That's also what I heard, the efficiency of the blower is basically maxed out, I will stick to 77

We (UPD) could have always made a smaller one but have to keep blower efficiency and bearing longevity in mind.

Words of wisdom go along way.Anything less then a 74 all your doing is blowing hot air.Then comes in the torch even more.
