Hi Jeff, Check out the SHURflo web site at: http://www.shurflo.com I bought my pump directly from SHURflo-UK and it was a *lot* cheaper than the distributer prices I've seen advertised. I tried a SHURflo 8000 series pump on my GSX-R11 T3 blow-through but ran into problems. I fabricated a vented oil pan that sat under the left hand side of the sump which the returned oil from the turbo gravity drained into. I then used the SHURflo 8000 series pump to return the oil to the crank case. This worked fine until the oil got hot (and I guess less viscus) at which point the pump couldn't keep up and the oil pan over flowed and vented the oil into the exhaust, and over the back tyre! I still don't like the idea of returning the hot oil from the turbo directly into the engines oil pick up, but for the time being I've admitted defeat with the electric pump and gone for the tried and tested route of using the bikes own oil pump to scavenge the returned oil. My new oil return system uses a 1/2" dia slash cut tube welded into the oil pickup at a slight angle, but it only sticks in about 3/4" so there is little restriction. I then fabricated a reed valve assembly similar to the design Rick posted, but I'm using a .120" aluminium plate with a large square hole in it. The the reed is made from .025" spring steel with a 1" by 1/2" wide slot close to the mounting screws to reduce the spring pressure. I drilled two 6mm bypass holes in the aluminium plate to aid priming and allow a little oil to free flow from the sump into the pick-up. I also riveted the ends of the reed mounting screws just incase one was to come loose and a nut get sucked into the oil pump! I've fitted a short flexible pipe from the new 1/2" slash cut tube to a -8 JIC male fitting welded to the back of the sump, this is connected to a 180 deg Goodrich fitting and a braided pipe that runs under the left hand side of the sump to a flap valve located at the lowest point directly under the oil cooler take off pipe fittings at the front for the sump. This system works perfectly, and there isn't as much as a hint of smoke from the exhaust even at start-up after the bike has been standing unused for days. Regards Tim Drew -- mailto:timdrew@cix.co.uk
