A drag strip just opened locally and I was talking to one of the guys that runs it. He just bought a cannondale and said he bought it for the sole purpose of designing a turbo system for it. He is in to the "fast and the furious" and has a mitsubishi eclipse with 600 hp. He made a turbo for it. The reason he said he picked the cannondale was because of the programable fuel injection. He said he cant do anything with a carb, but he can tune a fuel injected machine to really run. I was wondering if anyone knew how a turbo system works. I have an idea but was wanting some clarity on it. Would it be possible to put one on a c-dale. Some of the guys said if anyone could do it he could. They said he definetly has the resources.

 

a turbo could easly work on a dale if the pipeing was corectly

Cdale1

 

The compression ratio on a Dale is way to high to run a decent amount of boost. It would need a lower compression piston and while he's having a custom piston done he might as well go big bore at the same time. It would be awesome to have someone go totally radical like that and show how much power these things are capable of!

MountainMan,

Escaping exhaust gasses spin a turbine to very high RPM. (around 100K depending on size)
That spinning turbine has a shaft that spins another turbine... and that turbine is the compressor. It sucks in fresh air, and shoves it into the motor. The air pressure in the intake manifold created by the compressor is "BOOST". (PSI) Factory turbos (cars) usually make a conservative & reliable 5-8 lbs of boost. Some, more. (porsche, Subi WRX) Some aftermarket turbosystems can make 15-17 lbs... only usefull if the motor internals can take it. The more boost, the more power.

Turbos are not that simple though. With added airflow though the motor... you need to compensate with the correct amount of fuel. (bigger injectors, higher flow fuel pump, ect)

Theres more....... boost managment, knock sensors, ignition retard, ECU or AFPR.....

Hope I helped.

And then you got the diesel engines, like my dodge pickup, which is blowing 40 lbs of boost. (not stock, but holding up). Pushing 420 HP, 1100 ft lbs of torque ON THE DYNO!
