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 |

The only way to change CR is to change swept volume!
a longer rod doesn't change CR because it is ALWAYS LONG. If the rod was short at BDC and long at TDC that would be a different story. The stock bolts are IMHO not even good enough for a stock engine. The stock rod weighs 700+ grams and the weight tries iots best at higher RPM to separate the cap from the beam just after TDC on the way back down. Since the beam is so damn heavy the RPM really works on it with inertia. The ARP bolts are abot 3 times less elastic than stockers |
