so I'm watching this 13 years later hoping to improve my 2.2l performance and torque and the only thing that I understood is that I don;t know anything about engines. I'm amazed to see that difference of efficiency...
Pretty good video! Thanks for posting it. So what was the final dyno result? Where to get those inlet valves? What kind changes were made to the intake cam?
I seem to remember about 25KW. DOn't remember how much torque. But it was more that noticeable - that cruiser went like stink - especially on the dunes.
@@matttopp5515 On natural aspirated engines , the tulip valve on the exhaust side promotes better gas scavenging! the profile on the valve has a better contour . I have done the homework on Harley engine with good results! On blow engines is another story. The flowmaster shows some improvements. But the other variables , like cam shaft lift, round or square ports, etc. That particular chamber is a pentroof type, which I think , should not have those valves in the first place. On bathtub, or Hemi design works great!
More air means more fuel. It's very simple. Everything that has been done mostly isn't fuel related. Mill the heads.. increase compression and work the exhaust side of the port and manifolds.. maybe a different exhaust valve but I wouldn't go that far and be done with it. Increase compression and air going out then you gain mpg. Everything else will need more fuel. Another worthless video of misguiding information
