so, I have been thinking (not always a good thing)
If an engine is basically an air pump, and the objective is to make it as close to 100 percent efficient, why is the exhaust valve so much smaller than the intake valve? Forget emmisions, forget fuel delivery, just want to understand why this is so...it is so on most engines... Rich |

On Ljet,
You can increase the fuel pressure and add bigger injectors. I am only looking for a solution at 2.2-2.4 liters. Not a huge motor, not a wild cam. I thinking that there must be a good solid solution that has been developed for this. It seems that there are alot of people like me who would like a bit more HP, but not alot less cash. New valves etc are done with a normal rebuild, so that cost would be close to the same. New pistons and cylinders, figure 98mm or 100mm. A cam that breathes better, thats all. I am not looking for proprietary information here. I dont want to build a monster motor, I just want to stretch what money I have to produce the best bang for the buck. So, I would like to here is there are really any live people that have built a motor larger than 2056 with either ljet or djet,,,these people should still be alive, and the car hopefully is still in operation. It seem that a solution like this would sell quite well to the type 4 community...those of us that cant spend the big bucks.... Rich |
