just a little run with the new tune amd pumps

I have a s475/87 now and im just running the cast wheel. I will probably upgrade to the 11 blade next year.
 
How's that feel vs the 7-blade 72 you were running?

I've read that the 72 flows more than its 75mm cast equivalent.

Any major diff with the 87 vs the 83?
