Do...want?!??

 

For some reason, I am digging this Turbo Sprint. A/C, clean, turbo 5-speed? Anyone know much on these cars?

I'm a little puzzled at the possible difficulties in turbocharging a motor with no overlap in the power stroke.

 

Wouldn't all intake valves be closed at one point (because they can only be open for 1/4th a cycle in a 4 stroke engine), forcing pressurized air out a wastegate or through some recirculation?

Damn...that's a good question. Without googling the answer, I think it's all about phasing valve duration. Since you have 360 degrees of rotation, a cylinder needs to fire once every 120degrees? Valve duration is longer, but maybe the lift is lower since cylinder volume is less?

 

I'm looking this up...

 

EDIT: found something...tho I didn't read the entire thread...
