SN92(VR-4) vs Novi2000

[RedGTZ]

I want to get more boost out of my SN92 blower, they make 8psi max., and now here are my options:

-- Update it to a VR4 back housing and impeller, 14-15 psi max. (VR4 are now on Back Order)
-- swap to Novi 2000, up to + 25 psi

What are the PROS and CONS of the Novi compared to the VR4?

Does the NOVI require more space or it's about the same as the VR4? same mounting brackets?

What is the life of the NOVI in street/race applications? easy to rebuild? cost?

Does oil pressure from the engine needs to get to the blower?


My engine is a 2.3l Quad4 W41, all forged internals, bored up to 2.4l, cams, headporting, E-Honed intake man., full exhaust, Tec3, cowl hood to exit heat, etc... A front mount intercooler is mounted on this car with 2.5 inch pipes all the way.

Let me know what you guys think ;) Thanks for any inputs!

I would maybe try a Novi 1200 or the VR4. The 2K is a little much for a 4 cyl I think.

Thanks for the reply,

How much boost does the smaller Novi's can deliver?
