Dang, someone just posted a link (maybe that was PS???) to a website that had all the displacement breakdowns based on bore and stroke. If I remember right, .020 over was a 358, so .040 over should put you in the 366cc range. Quote
odaen Posted March 10, 2007 Report Posted March 10, 2007 Dang, someone just posted a link (maybe that was PS???) to a website that had all the displacement breakdowns based on bore and stroke. If I remember right, .020 over was a 358, so .040 over should put you in the 366cc range. @ .040 over, you have a 65mm bore, which gives you 358.4cc Quote
2003LimitedBanshee Posted March 10, 2007 Report Posted March 10, 2007 @ .040 over, you have a 65mm bore, which gives you 358.4cc Knew I should have found that chart before posting up. I did the calc real quick and came up with that figure, but I was sure that I saw .020 over at 358. Goes to show you, never doubt the math! Quote
87sheerips Posted March 11, 2007 Author Report Posted March 11, 2007 So 358 huh, thanks for the posts! where is this chart?? Quote
2003LimitedBanshee Posted March 11, 2007 Report Posted March 11, 2007 So 358 huh, thanks for the posts! where is this chart?? I guess the link must be posted over on PS, but I haven't been able to find it again yet. I know it was D.A.R.A or something, but when I typed that in I got the Delaware Amatuer Racquetball Assoc. so...? Quote
Bansh-eman Posted March 11, 2007 Report Posted March 11, 2007 the formula is : Stroke in mm X Bore in mm X Bore in mm X .0007854 X number of cylinders... so a 4mil 68mm bore would look like... 58x68x68x.0007854x2=421 Quote
