banshee370 Posted January 6, 2004 Report Share Posted January 6, 2004 I'm curious if you have ever delt w/ case stuffers and your opinions of them. I just finished re-assembling my cases, and being that I swapped the cases out I had to fabricate and install another set. My motor builder had told me that if I didnt run them with my current configuration that the motor would be "lazy". I'm just curious if you have ever messed with them and what you think about it. Here is a pic of the set I just made before I bonded them in. Thanks in advance Quote Link to comment Share on other sites More sharing options...
PassionRE Posted January 6, 2004 Report Share Posted January 6, 2004 I havn't stuffed cases on Banshee motors mainly because they are major "stuffed" to begin with compared to alot of 2 cycle engines. Ive never noticed anything on stuffing motors traditionally as in crank plugs etc. in performance as far as increased transfer pressures are concerned except where radical transfer durations are being used.. What you've done there will help in performance but not because of what you think. The angle that you've changed on updraft entrance will increase flow because of a less turbulant entrance, which is where your gains will come from, not increased crankcase pressure. Not saying increased transfer pressure wont give you gains, you just wont notice it as much unless your transfers are advanced alot earlier than normal. My main concern would be one of those baby's letting loose at about 10K...ouch!...Jim Quote Link to comment Share on other sites More sharing options...

banshee370 Posted January 6, 2004 Author Report Share Posted January 6, 2004 Thanks for the reply. My current motor was designed around running methanol & race-AV gas, but I'v only run race fuel (fuel economy reasons) With the way things have been going for me I think I am going to stick to race fuel. There are pics of my cyls (ported) HERE I may have a port map lying around if that would help. Dave (MP) made a lot of alterations to the transfers, so I think the gains in crank case pressure may help. I'm running right around 225# compression so I've gained my low end back from that. I see now what your saying about the updraft entrance, and with that in mind do you think this is a bandaid for poor design? I'll try to get a pic tonight of the stuffers Dave made for me. The last set I glued in I was unable to remove. Then forcing me to make another set. The only way to get them out would be to destroy them. I too hope they dont get loose at 10k! That would be ugly ...... VERY ugly! Thank you again. Walter Quote Link to comment Share on other sites More sharing options...
