blah, I sent my head off to get treatment from a computer measurement machine this week. I'm working up manifolds on both sides of the block. This is for sure, neither side of my engine supports a supercharger my goals are a little modest for that. That is an intiguing sequential setup though.

Actaully I said itd be funny to hear someone mouth it off, because its so rediculous to have that many different systems combined into one. I'm not 15 I'm 24, I'm also an aerospace engineer who does this stuff in his spare time. I'm the only vendor of adaptronic E.C.U's in north america, and I engineer all my own components. I wasn't really contemplating on a hearing of the twincharged setups or even debating them. I just wanted to see the other twin charged setups... I don't quite know why all this is so hostile. Jeeze I just wanted to see who had them and what their plots looked like.

I just wanted to digitize the flanges, but he said he'd be willing to cut one open. I have one cylinder lapped and ground for airflow testing. I've got an ITB kit I've been putting together and I wanted to play with that entry angle. I can't believe the stock manifold comes in flat to the head. It makes no sense. Have you done any research playing with it?

I have not done any research, other than giving a 99, 94, and (hopefully...eventually...soon) a worked aftermarket head to a CNC shop for flow testing. My old boss actually. He has flowed the 99 head and said it sucks (obvious too looking at it compared to other's), but he's comparing it to the other heads he does. He has a few head porters and a digitizer, and of course a bunch of 5 axis machines. Where I work we also have the same digitizers and a 5 axis machine and we do ports here, but mostly prostock-style stuff so far, and all for the owner's *****-n-giggles (nothing ever for production, we're not in the head porting business). The machinist here who runs the 5axis and digitizers the most said he'd make a mazda head with honda ports (or whatever), but I'm not about to go thru that. I don't think I want to afford just the raw material, especially if there's an "oops". And I run a street car that needs to stay cool.
I don't have the desire to make a fancy head, and if I did, I'd make one, use it, and move on.

why did you come to miataturbo.net to talk about superchargers? You should go here: www.superchargedmiata.com

If we're talking about ridiculous setups, I've contemplated twin turboing my ITB setup. I figure if I rebuilt my motor with a ported head I may get enough flow to spool two small turbos alright. I'd do it totally ridiculous too, two seperated intercoolers, and each turbo would feed two ITB runners. That may actually happen too, depending on how much money I have when my stock motor goes pop.

Some technical data although in German)
http://www.volkswagen.de/vwcms_publi...tail.0.10.html
170 bhp, torque 240 NM from 1750-5000 rpm, 7,3 l/100km (I'm sorry i dont know how many mpg this is) And if it is build for Germay - it has to be completly reliable even for long full speed runs at the Autobahn. So, I would love to have such an engine in my Miata... (Or better the 2.0 TFSI...)
What I would like to say - it sure is possible, but you need a lot of engineering and money and experience and..... to get it running reliable and strong and with a sensible behaviour. (Volkswagen can manage this - but for DIY... I don't know.)
