Alright I am running a V-2 and I saw 10 psi with a 3.33 non-intercooled. and 6-7 psi intercooled.

My friend: has a V-1 and is running the 3.60 pulley-Iguess that is 6psi? right?
Anyways I am installing the fmic like Ihave on his car and what is the smallet he can go with stock injectors? what disc to use in fmu?

i was figuring he could go 3.125 with this set up with just a different disc? Is this right? Stupid V-1's !!!!!!

hey I just noticed the difference between the v-1 and v-2. Its the impeller!!! the impeller on the v-1 is all straight and the v-2 has curved vanes!!

Here is a linkhere

what the hell are you talking about? A impeller is curved right, to pull in air which would make the blades curved. So if a V1 doesn't have curved blades how does it suck in air? You friend can run the stock stuff with the 3.125 , I am doing it. What ever disc came in the V1 kit in 1999 is what im running. I think it's a 6 but don't quote me on that. I like my V1 alot! The gears are stronger, and a V2 is more quit with 1 extra psi so...Being along term V1 runner my car sounds strange with out the noise.

The early V1s had straight vanes. Later models had the curved vane impeller, which I believe is the same impeller as the V2.

My V1 has straight vanes and lots more than a V2. I was also confused as to how this produces boost.

Straight vanes throw air out radially along the vane surface. Since the vane is rotating, there is also a tangential component to the velocity vector of the air molecules. The air molecules travel outward until they hit the scroll. The scroll channels the air to the blower outlet by converting all the air velocity to a tangential direction.

A curved blade imparts more tangential velocity at the expense of some radial velocity. This is more efficient because there are losses associated with the radial velocity component when the air molecules hit the scroll. (The same happens when air flow has to make a 90 degree turn in an intake circuit.) Less radial and more tangential velocity results in lower pressure loss within the blower.

My V1 has the curved blade impeller.
