oh no doubt DonR put alot of work into it. afterall he did design the Monster 007 manifold, which any serious 1.8t guy should know was the king of the hill for ages.

APRs manifold with 75mm RS4 TB is still a tough one to beat. arguably better than SEMs manifold.

i considered running the SEM with a 75mm when i had my car, only because DonR offered me an amazing deal, but as you know things happen and car projects end.

Bejan (boostinbejan) made an amazing manifold for a while. he did alot of flow testing with various plenums(he used to work for Dinan, so he had access to such machines) he called his “inlet dynamics” i havent heard much from him since i got out of the 1.8t world.

but we both know, anything will work better than the stock junk. have you decided on a throttle body configuration?? driver or passenger side?

do a Force Fed Engineering Outlaw style center inlet. :bowdown
