With all of the talk about light weight, high horsepower replacement engines for our favorite Porsche, have we forgotten all of the lightweight, high revving 4 strokes out there? There are dozens of possible alternatives currently being housed in various motorcycle brands. Are there any working examples of this type conversion out there? Thinking besides the lightweight, they tend to be compact and have smaller cooling, electrical and mechanical systems. Would seem using one for a conversion would be a no brainer. What am I missing?
Thanks |

Ever seen the connecting rod of a Cummins big truck engine? 14 liter straight six with a connecting rod almost the size of your forearm. Funny thing, that engine only puts out about 400 horsepower, as much as a healthy LS engine.
So why is no one putting LS engines into over-the-road trucks? Exactly the same obstacles. You can put a rev-happy bike motor into an EXTREMELY lightweight car and it will be at home on a race track, there are lots of examples. But when that same car is over 1000 lbs and in traffic the benefits disappear in a hurry and its life is shortened exponentially. No joy. |
