I haven't seen any comparisons ,of wave densification projections between dry and wet runners.The tuned, wet runner should obtain higher densification potential,(ram tuning), but the fuel will displace "some" air compared to the dry runner. Depending on the fuel involved, intercooling should occur in the wet runner. Anyone ? roverman
Dont have an answer to your specific question..
But I do know that E-85 does require a somewhat larger runner with more volume to make up for the greater amount of air displacement compared to gasoline...
Some really cool research has been done with the new "wet" flow technology developed by Joe Mondello.. Wish I knew where to access the pertinent info...other than the changes to heads and intakes that Dart made after Maskin ordered one of the first units.
If I recall correctly, "stoich" for E85 is approx 9.7/1 ? Folks running E85, usually run 2-4deg more timing than gas at lower rpm., and then roughly parrallel to gas , on up. Since ethanol/metanol carries its own oxegen, I'm not sure wet runner needs to be proportunately larger than wet gas runner.
Friends I race with all say.. Larger runner for ethanol due to volume of fuel in suspension..
