Bigger throttle body
He had the same powerplant as you with the kleeman blower and such. I recall reading about a CL600 TB that he got to work somehow. I assume the the V12 TBs are probably 80mm compared to our 74-76mm(?).
At one point I had an ML55 TB that I was going to send out to be ported with a new butterly cut, but I held off for some reason. I'd buy a used extra if I was to go this route. Not sure if all N/A M113 TBs are the same mm though, probably doesn't matter if your going to punch it out, but you can't get to 80mm with ours, which is why the CL600 TB was probably used.
Post up if you get anywhere with this.
I read somewhere the E55K guys are doing a simple port job on the stock Throttle Body inlet/outlet and NOT changing butterfly out..... for some gains.. Can this be done to my clk55K for some gains?
