I see someone already tried to make a manifold that is extremely similair to this test one
I wish there were some more specs on what that guy made. From the pics it appears that his runners are WAY too long... pretty much making it a better flowing stock intake.
Anyways, I have been making lots and lots of different versions on the intake manifold and I am learning alot about it. I finally figured out also how to completely mimick the whole intake cycle for each cylinder. It takes my poor PC a VERY long time to make these computations but it looks pretty cool when it finishes.
I have also been doing alot of research on exactly how to actually produce these things. Id like to be able to make it so that I could offer them to the public for an extremely cheap price compared to most sheetmetal intakes and make them flow better. Ill keep you guys posted as I get further.
I also am going to start making exhaust manifolds that are equal length and everything else. It will take awhile to simulate the exhaust pulses accurately but I will be able to actually put a turbine wheel on the end of the manifold and simulate spool characteristics and total flow. It will take awhile but will be nice when done. Theoretically should be extremely good.
Does anyone have any requests on either the intake manifold or exhaust manifolds? Right now the intake manifold I am trying to make the best I can with the stock throttlebody up to a 75mm one and try to keep extremely close to the stock upper intercooler piping. As for the exhaust I am thinking to make it bolt up to a T3 style turbo (GT35r type) but I could make it divided (So it could work with a T4) but then let people choose the flanging on it. Anyways, just wanted to keep you guys updated. The production costs seem to be a decent amount so hopefully I will be able to make it so others can get one cheaply instead of just making a few for myself and our cars here.
