Nice vid!

They had them at EKW complete engines for less the 650aud one time they couldnt get rid of them even had 2 for 1000aud at one stage.
Super efficient design looks at the conrods less than 400gsm or titanium weight for rods of the same size and most of the engine is motorbike based technology. If you get a chance try to looks for shots of the internals, very impressive!

the MA09ERT seems to be a great little engine.

i found this video http://www.youtube.com/watch?NR=1&feature=endscreen&v=mIQGkaMunYc at 2.47 it shows how the turbo and supercharger work.

from what i see when the supercharger is functioning it air intake path is from the turbo but when he turbo kicks in their is a bypass valve that bypasses the supercharger and the turbo outlet goes to the intercooler.

Anyone know what the factory valve looks like i tried to find one online but seems impossible to get information about it.

Thanks!

2 choices available from factory already setup for you but need at least a t50 gearbox conversion for one and the other something similar custom adaptor plate to bolt up.

They are capable of way more hp than stock.

i guess a wastegate would make a good bypass valve, though i didnt think these setups use bypass

look it's a wiki for it!

You don't really need bypass valves. I guess the advantage is having boost for that small part between idle and spool up or between off throttle and spool up. Any simple control setup will have a peak just before the SC cuts out if the turbo feeds the SC.

If the SC feeds the turbo then there's shouldn't be a noticeable switch because the SC is positive displacement. The turbo may pull a vacuum after it until the clutch is disengauged.

If you're engine bay's the same as mine there's not that much room in there for all that plumbing and pulleys etc.

An alternative is living with having the turbo boost come on at 2k rpm or 3k rpm (depending on where you want it) and using the gears. Most cars have gears anyway

+1 RC, it's doable, but there's simpler ways. IMHO

There are a few cars around that are s/c and turboed. watched a couple on youtube, they seem to go quite fine

to come to think of it it seems to be more difficult than i thought because after the s/c is disengaged assuming its plumbed in series with the turbo charger the turbo will need a bypass valve to allow another air source?

and if you were to leave the s/c and turbo running together the difference in efficiency would cause a increase in intake temperatures i think.

Any one know of a bypass valve that could be used after the s/c is disengaged?



or maybe this whole idea isnt really worth it whats a good size turbo that pulls from 2000rpm up? the less laggy the better imo.

Thanks!

to be honest, i think it's a shiet idea trying to combine the two when all you need to do is properly size your turbo

A mate was fizzing to do it to the CA18det in his esky van. We discussed it at great lengths. It's not hard, BUT it's very difficult to get a smooth transition between the super, and the turbo. The very simple design I thought would work very well would still give a drop in performance at the changeover point.
Also, if the turbo blows into the super (Even with a bypass butterfly) the charger will recompress the turbo boost, and amplify it by the Boost ratio. Then when the blower cuts out, the pressure at the manifold will drop.
