All vissual excitement but one throttle body on Plenium chamber , still works best, as with that set up, can't get each throttle body perfectly same. heat & stress at high rev, they will always be a bit different. a polonium chamber, stores all the air the engine needs & one throttle body can supply same air per cylinder as those four individual . have seen results on Dyno while i was watching them change set up's on race motor.
The guy that has had it custom made by RPW is going to use it on his Hyundai track car.
Just waiting on these little beauties to turn up now
Craig, looking great, that system would be more for high rev, the tri why more for street. when i said one throttle body on a plenium manifold, did not mean stock, a custom designed plenium manifold , & if the single throttle body is same size an same as those four individual , it will flow same air to each cylinder, as the single runners only flow air to one cylinder, so no more air will flow, the flow bench can not duplicate high rev stress, my friend monitors everything combustion chamber heat fuel efficiency for each cylinder afr of each cylinder . he has it all on his engine Dyno with motor in a bomb proof room with armoured glass window. he also has a huge 7 vacuum motor flow bench he built himself that can flow complete motor. he has a machine shop with best of everything . he builds then tunes to customers requirements or delelop's race motors or anything people want. i just watch once, when he was tuning a customers clubman, had a Toyota 4 cyl with a set of single runner TB's like that MoTeK or Ortronic ECU? customer wanted more, he made the polonium chamber stores enough air where motor can use it, one TB for accurate at all rev air control, it was EFI so fuel injected in not drawn in. i saw the dyne test's, was not that much difference but when you looked at quality of HP & TQ delivery was much improved. then you have to have a driver that can use it!have you got all your gear on yet?
