Seems like Jake will be out of reach for the next few weeks...so...anyone know the cost differance between staying at 71mm and upgrading to 78mm stroke?
my rods already need to be re-worked due to the pistons I'm going to use, so no loss there, I'm guessing new rods would be in order for the longer stroke....I have no idea what crank is going to cost, nor the rods....can a 1.8 crank be used so that I can at least sell my 2.0 rods and crank to help cover the additional costs?? |

QUOTE(Bleyseng @ Dec 13 2004, 11:07 PM) Why keep increasing the stroke? Why not increase the displacement to 102mm? Why not just do a 102x71mm engine? Geoff I believe these motors are more effecient with longer stroke combos..the cylinder is so big and with small valves that the motor needs the extra time for the stroke to go all the way down to really fill up the cylinder with air and fuel...something like that if that makes any sense (IMG:style_emoticons/default/smile.gif) the cost of going to 102's gets expensive real fast, the pistons cost more and I'm pretty darn sure at that level "real" head work is required......my heads are already done and most of the engine is paid for....or so I hope (IMG:style_emoticons/default/wacko.gif) |
