    New 81mm E2B Cylinder coming from ESR.

    One very interesting feature is the water inlet into the cylinder is relocated to the exhaust side.

    That’s the size cylinder I run with the 5mm crank. Was that water inlet relocated for better cooling features or for clearance? FWIW my ESR 420 runs at 150-180* consistently! It has yet to over heat on me.

    Pipe clearance would be something to confirm for sure. We will see when these come out and start getting used.

    If used on a drag engine, wouldnt be any issues because of pipe location. With the PV valve though, it could be used for other types of racing. Surly though, there must be a new pipe coming out just for that cylinder if used for anything other than drag.

    I like the 81 MM, nice option of a 81MM bore CEO, good to see the added casting height & longer rear two studs just Like the CP Industry Sphynx, Lynx, Puma and Saber cylinders; don't care for fresh coolant inlet directly into exhaust.

    Development takes different paths; right ones as well as wrong ones...Without being negative, and understanding the thought behind fresh coolant into the exhaust track, in very simply 'layman' terms; IMO NOT A GOOD IDEA. Realizing manufactures have over many years tried this very concept and always moved away from it. Good engineering & functional reasons why coolant is first introduced into a cylinder on the intake side (coldest side of cylinder) and not on the (hottest part of cylinder) exhaust side.

    I think it's going to work out great. Eddie spent a little more time on this new cylinder than a quick thought.

    Looking forward to getting my hands on one as well as the new CEO pipe.

    Agreed. Like over twenty years time, on this cylinder design. He deserves a lot of credit.
