I was having a discussion with my mechanic about the best solutions in EMs.
He suggested that a length increase by the making of a tubular manifold will give more benefits to the engine and the backpressure,along with a better design of the EM rather than get a similar EM with the OEM unit that has only larger width of the tubes.
My physics is rusty,but only thing i can think of is that on an increased length and same width EM we gain in exhaust fumes velocity-hence faster spooling of the turbo.ON the larger width i get less backpressure and more lag for similar reasons.
WHat is the best solution to this?
Im keen on getting the manifold that Carsten makes and probably will,as my goals are not a 7xxhp car,but a long lasting good old 500hp at the most as final improvements,maybe less.I would like to know however what are the pros and cons of these 2 types of EMs
On the oem EM,the fumes from cylinders 1 and 5 seem to go against eachother.I know that the fumes go out in pulses,but on high revs this kind of diminishes.SO on an engine that produces most of it's power on higher revs you get more backpressure.Does a longer tubular and specially designed EM get over that?
