the turbo and the whole setup in general is all stock. we just drove the car once in turbo only form. pretty smooth power delivery (stock turbo). think it makes boost pretty early like 2000 to 2500/min.
the only added parts are the albrex-centrifugal charger and another stock intercooler after the albrex-charger (the air-route after the charger -> intercooler is the original way)
all we found out about these centrifugal chargers is that they should have a internal variable ratio to make the best out of them. especially for low rpm. this is pretty logical if you think about the turbine style of these compressors. the pity is that this albrex unit seems to have a constant ratio - no variomatic stuff ...
it looks like we have to visit the maker/seller of albrex.
thats the company - www.motortuning.com
they made some fast porsches in the 1980s. now they do sheiks ferraris and rich mans lambos and such.
back to the clutch problem...
having a clutch would give us the option to find a better ratio to get some real boost up to lets say 3500 - 4000rpm. then we could look for a well sized turbo to take over at this rpm level
isnt there any of the shelf clutch available for such operations ???
