I am interested in building a 2270 engine. From what I can see I will need a stroker crank with a 78 mm throw. I am concerned about which rod to choose. I have seen stroker cranks with VW type 1 journals as well as 2.0 liter and chevy. I have noticed variations in rod lengths as well. I am in need of some advise on a good, proven combination. I know there are many good engine builders on his forum that could share their knowledge on this subject so please do...............Thanks

Sure, if you never use WOT you won't produce more heat. So who builds a performance engine and never uses wide open throttle?
An internal combustion engine is only about 30 percent efficient and the other 70 is heat. No one changes that. If/when that higher HP performance engine gets onto a track or is driven for any amount of time at WOT or under load you need to disperse more heat. Making it more efficient only means the percentage you have to disperse is a bit less, but double the HP and it's still a LOT more heat, regardless. That's physics, no getting around it. |
