Very curieus how well or wild this cam is or isn't.
According to my idea, this should be ~perfect, but I'll have to check that firstly of course
Case is now split and parts scattered all over the place. You know how that works..
Dam... No need to PM you with cam questions. Thanks for sharing.
What do you plan to do with the manifolds? Surely you will not just bolt them on?

ive got gun, blaster...... is it Teflon that you mean, or ceramic. what is the procedure i am really interested? seems that youre mentioning home aproach
cheers
you clean the part in thinners or acetone, blast with a set grade media 120 grade if memory serves me. then clean and dry, spray with DFL-1, dry and bake for 1 hour at 150 degrees C..... bascally
would be hand in turbo applications in key points i feel....

They look to be flowing way more then the mexican EFI intake system I had on the engine before
hello,
for sure..., what can be more restrictive than the mexi intake... i take off mine of the engine this winter also...they need too much welding/porting...and even with that, runners are really small in diameter...
Why? Air doesn't flow down both ports at the same time, it would be better for charge distribution if there were a generous radius instead. But with how thin the material is, I don't think that's possible. Leave it as is wally, you'll be fine.

I agree Nick, thanks for wording the underlying theory behind it

For the record: the above isn't compound turbocharging like I am planning. Its a nice system too though, very much like Toyota's twin-turbo Supra's or TSi from VW with a compressor acting as the small charging part.
Unfortunately it works with flaps and (check) valves, which I think is only practicle for an OEM application: the exhaust flap en check valve require delicate control and long testing before everything comes in just at the right moment.
I don't have that time and don't like the idea of the complexity of exhaust flaps and check valves. It needs to be a little simpler and compound charging should be able to give that I think.
Only advantage I see is that the check valve routing means you only need one intercooler to route both through.
