Well I was able to get my brother Jake over today to give me a hand with getting the blower upgrade underway. Anyone who thinks the blower is just a small bump in size from 2.9 to 3.0 is completely missing the boat! Huge differences! The new 3.0 is TALL. Rotor pack is much shorter which will allow a higher critical speed (not to mention 4x3 instead of the old 5x3). The snout is now wide open (something the 2.9 couldn’t get even after porting). You’re able to bolt it down to the heads without removing the lid. And the difference in heat exchangers is crazy. The new HX is dual pass and massive…takes up the whole lid (the 2.9 used two smaller HXs as pictured below). Unfortunately for me the new pulley is 5-bolt with a bigger hole for the upgraded shaft diameter, so my 4-bolt 2.9 pulleys do not work on the new blower. It also appears that I can just bolt up my Katech 112mm TB without an adapter too, so that’s nice. More to come as this gets underway….
