type4 scat cam lifters problems/dry sump routing

[Sean rupp]

I bought a buggy with a type 4 engine in it to use in my speed buggy. The engine had 2 lifters worn down 1\2" each. I replaced the cam and lifters with new scat pieces. I now have a 104 bore and a counterweighted scat 66mm crank with h-beam rods. The heads have been ported and decked a bit. Im going to be using a cb fuel injection unit on the motor. I run sand drags and asphalt with the car. Now that the engine is all back together i start to hear that the scat problem may not be an isolated problem. Has anyone else had bad experiances with this equiptment? I am also looking for oil passage routing info for the type four motor. It has a dry sump system and i want to make sure it is plumbed in and out correctly. any help would be appriciated. Sean

I run a dry sump on my supervee motor, but there's three different pumps out there that are common, SCAT, CB Performance (Schadek) and Bugpack. Scat and Bugpack are 4 port pumps, the Schadeck/CB is a two port pump. I use the 4-port Bugpack and use the stock internal pickup so I had to block off the suction stage external input port. The output port goes to the cooler, and then to the top of the oil tank. The output of the oil tank goes to the input port of the presure stage, and the output of the pressure stage goes to the oil filter. The output of the filter is plumbed into the block using an adapter plate at the original oil cooler mounting location. The output passage in this plate must be plugged and a bypass plate must be installed over the original oil filter mounting location. Carroll Smith's book on racing cars "Prepare to Win" has details on this and a host of other topics to keep the car from crashing and the engine from blowing up.
