using the vacuum lines, when a certain pressure is reached, an actuator opens a valve and the supercharger is bypassed.

Re: turbo charging
why would he twin charge a car with a variable vane turbo? wouldn't the extra weight negate any benefits from the reduced lag times because they'd be so small

Last I heard he was having engine troubles which were unrelated to his boosting (block was cracked prior). On a petrol engine there're several big problems to work around. One of the main ones is what to do with that much boost? I plan to fit staged turbos to my diesel truck, variable vane for the small one. It's a work in progress. |

Re: turbo charging
this is on an 8-valve Golf MK II GTi. garrett varable-vane (looks like a T3) and an AMG supercharger. it sounds mental. serious machine, they're looking for 350bhp @ the fly. it's going to be used to hillclimbing. i'll try get some pics today.

Seems like a redundant experiment if going fast is the goal, but worthwhile if the goal is to build something interesting and different. |

Re: turbo charging
i dunno the goal, they told me they wanted the supercharger because there's no lag, then when the turbo's spooled a valve opens and bypasses the blower. but with a varable-vane that seems pointless, seeing as how the turbo pretty much has it covered.
either way, it's an awesome car. sounds like a beast when they give it some.
