This statement isnt true. The larger stroke CAN play in revability. But the amount of time in vtec statement is false. You engage the 2nd cam lobe when the motor is capable of using the larger amount you are giving it. I larger motor is going to suck more air at a lower rpm than a smaller one, so vtec could be in the 4k range rather than 5500 or higher. Head work also has a lot to do with that as well. A worked head will flow more air than stock one thus allowing you to give it more sooner. BUT, you all motor guys are all about some big cams and the primary lobes on them are so large that your vtec usually stays pretty high.Originally Posted by IDriveToast
I am sure someone can find you a picture of a "stroker" crankshaft.
