Fitting "vulture Motorsports" Intake Manifold Rb20det

[fijiboy-jb]

Has anyone fitted one of these intake manifolds to an rb20det and with how much success? cheers

They don't "do" anything. If that's what you're asking.

but it looks pretty, I mean pretty shit because it's a Plazmaman knock off that has ghastly looking welds.

Depends on what you are trying to achieve.

Over 6,000-6,400 rpm where RB20s often start to nose over in power provided you have a happy turbo that makes power (ie not a std turbo and something bigger than a GT2860/HKS 2530 then it will hold power and make more power up top. Trade off is it will cost you some mid range torque and at 4,000-5,500rpm you could find yourself losing 15-20rwkws....

Below is not a single other thing changed other then plenum and associated inlet pipe changes....all on 98

In my case I made something like 15-20rwkws less at 4,000. But at redline/around 7,500rpm 30-35rwkws more on a psi less boost.

So since my car is what I would call a track-street car I often am reving the ass out of it so whilst I rathered I didnt lose all that power on the left hand side of the cruve....when I went E85 it did allow me to exploit the extra boost and revs to make considerably more power up top over 6,500rpm

Odd are on E85 with std inlet it would have nosed over a lot more on E85. Not saying its a great mod...but certainly does change things.

All in all I would run the std manifold and wouldnt bother with the Plazmaman inlet. Though some have had better luck than me with regards to response

That said, If I ran my old Greddy exhaust manifold instead of the 6boost I reckon the setup would have been pretty wicked as would have been the right combination of mid and top. I lost more mid going to 6boost from Greddy manifold than I did from std inlet to Plazmaman plenum which is what the Vulture manifold looks to be a chinese rip-off
