VT 355 supercharged AFM issue

[kojab]

Without a doubt the worst racing? manifold I have had to deal with. At one particular RPM range we could not overcome a lean spot The only thing good one could say about it is "It looks nice"

I agree we fitted one (at customers request) to a mild 5.0 and it lost 20rwkw against the std manifold.
We have done a lot with the harrop manifold and 1000cfm throttle bodys on big rpm stuff and they are pretty sweet, but as i said the come manifold is pretty easy to work with and isnt super bad in boosted application and a damn side cheaper than an original group A

I heard similar issues with their ecotec twin TB manifold.

Any of you guys delt with the motec twin throttle first hand?

I understand all the things your saying, but how much worst is inlet temps with the carby style setup as apposed to the inlet from the air box area ?

that's the only let down I reckon of my mates motor, it has torque power dual plane low rise and 750 cfm crd throttle body, was nice to work with but got so much hotter inlet air temps

thats why you need one of them big air dams like the old v8 supercars used to have haha
