    Which manifold to use with novi's

    Got a deal on the novi's I wanted but they don't come with the manifold. What kind of price/availability am I looking at here? Who makes the best manifold for them?

    I need links " "

    i have a protec i think, i got it bundled with my novis/vf3's so i cant comment on retail pricing, riva makes them too from memory.

    I have 2 GPR intake manifolds for sale

    Used Riva - $85

    New (still in package) Protec - $125

    Either one will work fine.
    shipping in US / Canada - $15

    I still have a few intake manifolds that were made by SpeedWerx and machined offset 50mm opening to match the offset of the Novi's. $150.00 plus shipping call me if interested 713-875-1812

    I haven't tried the speedworx but everybody tell's me they are awesome.

    I found a picture

    I had them all, Riva, Protec, R&D. For the Novi's these are the best, not only their offset match them but larger opening will make sure that there is no catch in the flow.

    Fercho: what sort of gains did you record using these modded speedworx manifolds over something like a protec with a set of novi 48's?

    izzo I did not record any gains. When I got my Novis all I had in had was a protec manifold, I had to fit it and grind here and there to make it work with the Novis, very time consuming if you do not have the right tools, some people actually elongate the mounting holes of the carbs to align the offset, IMO this is not the way to do it, I should not have to machine or grind anything to make the carbs fit the manifold that was build for them. SpeedWerx seem to be the only ones that actually took time to developed a perfect fit manifold. the other thing is the size of the opening on the back end of the manifold, its larger than the Protec which has the same oval opening as the OEM manifold.
