Is it possible to do both. I know that the supercharger is on the intake side of the engine and the turbo is on the exhaust side. Could an engine handle both, or would that be too much pressure?? If it has been done i would be very interested to know about it. PICS if possible

 

I don't know about car engines but yes it is possible because volvo penta has it in some of their marine engines and let me tell you that it kicks *** no lag at all I am sure it is expensive though

 

Read the ultime car shootout by scc. The one where the ferrari won. There was a supercharged and turboed mr2 ? or something in the test. It was really unreliable though.

 

Nissan was the first japanese automaker to release a double-charged engine in a production car. The 1989 March super turbo used a supercharger and a turbo on its 930cc 4 cylinder single cam to make an earth shattering 108hp and 96 lb-ft of torque. The curb weight was 1697 lbs. The original engine was 1 liter but it had to be scaled back to to compete in Japan B class.

But in the real world its not worth it to do both, instead of doing both half assed, just pick one route and do it good.

 

HKS used to sell a turbo kit for the supercharged MR2. This was called the twin-charged MR2. Since the SC had an electronic clutch, it was possible to use the SC down low, then shut it off, and let the turbo take over.

I think with new technology, if you wanted to spend the dough, they have electronicly assisted turbos(theyll be used on the GTR actually), they use an electronic motor to spool the turbo.

 

Very true, this is one way to spool a bigger turbo. The SC would kick in instantly and provide light boost to the engine which probably won't improve your lauch much but would definately feed the hunger of the turbo spooling it in about 1/4 the time providing you with full boost much sooner. A clutch would eventualy kick in and disengage the SC so as to not damage it.

The only thing is with modern day turbos there are better and lighter sollutions to spooling a big turbo. Match a ball bearing turbo with a two stage nittrous system and you have a fast spooling turbo system with only the weight of a few hoses and bottle. You can event use a TT setup that uses and smaller faster spooling turbo to feed the monster. Still not anywhere near as heavy as a SC but just as effective.
