turbo crossflow questions

[Jimsiss]

just a couple of questions concerning the turbo crossflow project

 

won't the exhaust gasses slow down if you make that sort of exhaust manifold, surely a free flowing one where all the primaries join together at the flange (keeps the speed of the gasses and reduces turbo lag, well as far as I can work out) like on my bros mates turbo polo project, here is the manifold that he made up for it (while he was in the planning stages):

 

 

and surely for the turbo oil feed you should use an oilcooler take off that goes between the high pressure oil pump and the oil filter, this would allow you to get a constand feed to the turbo improving cooling and lubrication and you could run the return from the turbo through an oilcooler to cool the oil off again so that you don't get a constant supply of hot oil to the turbo.

 

I think that was all if not I'll let you know

spot on fella, and your manifold is well tasty!!

maybe you should volenteer to make the one for project crossflow turbo!!!

its my bros mates manifold and it is spot on, all you need if the flanges cutting then use exhaust pipe bends that you use to make custom manifolds, tack weld it then check it then weld it when you are happy

I would do it as per CVH, T-peice on the oil pressure switch straight to turbo, and your direct return to the sump will be fine, it works on every other turbo engine ever designed, why complicate it will unnecessary oil coolers.
