Which supplier has the correct APR connecting rod bolts of 2.0 rods?
AirCooled doesn't carry them. CB Performace has APR bolts but I don't know if these the correct/best ones. Paul |

QUOTE(Jake Raby @ Oct 8 2004, 03:18 PM) a longer rod doesn't change CR because it is ALWAYS LONG. Ahh, I was going to argue, but now I understand. Modifying the rod will change the uncompressed volume and the compressed volume by the same amount. i.e. A smaller amount of air/fuel is being compressed into a smaller space. To bump CR you need a larger (or same) amount of air/fuel being compressed in to a smaller space. I suppose one could argue that there is a miniscule CR increase because the % of volume lost at BDC does not equal the % of volume lost at TDC. But I'm splitting hairs. 4 in^3 / 2 in^3 = 2:1 ratio 3.998 in^3 / 1.998in^3 = 2.001:1 ratio |
