We are on the verge of releasing our new 04.5-07 CR pistons in standard and
+.020" bore. Another thing we are excited about is the release of piston blanks. These pistons will not have the oil galley in the crown and I believe will fall somewhere between the steel pistons and the OE in terms of how much heat soak they can handle before melting. They are almost identical to the OE bowl design except for the CC and compression ratio. We are shooting for 17.9-18.3 depending on your block and head gasket.
We are also looking at releasing a finished blank with a flat top. The piston will be finished except for the final compression height and the bowl area.
I believe there is a need in the aftermarket for oddball pistons that can be made into whatever you want. With these new pistons you will have the capability to make whatever kind of bowl you want, either by machining yourself at the local level or by choosing one of our pre-designed bowls. The possibility will be there to run so much compression you can blow the side out of the block or merely match the bowl to your aftermarket injectors. I have found that on 12v and 24v blocks that somewhere around 22:1 and higher with a good flowing head and complimentary cam in the 45+psi will split the block :doh:
I think it will be interesting to look at all of the John Deere, International, Cat and other piston bowls that were designed for the injectors that we are using and machine the "cummins" pistons with a bowl that compliments that injector or tweak further.
Question: how many people are interested in a piston they could machine bowls for?
