RACERAL Al before installing the motor, either Call Dove and ask about the water pump having an anticavition plate on the impellor. If they don't, get one. I don't have alot of faith in this company. They used to be the only ones making FE parts. They sold all types of different heads, intake manifolds, blocks, and every other thing you could think of for the FE motor. These where good design with poor machine work or casting. Pouring aluminum is a gift. I used to do it in Macine shop a long time ago. I have a can-am
oil system and have no help with info on this setup. I even stopped in 1 year to talk to Jim jr and he knows nothing about his products.
Suggestion is pull the water pump and remove the back cover and check the impellor. If you are careful a little thin coat of rtv,( thin coat) and reuse gasket and cover. Medium loc-tite and don't over tighten these bolts, or button head bolts.
I also think that Doves has their own impellor design. Not 100% sure on this. Good luck with motor and car.
Alt will be fine even if it is underdriven. As long as it gets a signal to turn on and charge you are good. Another note, run a voltage gauge in the car and not an AMP gauge. The amp gauge Can't handle the ampage if the power all goes through it. The terminal plastic sleeves will melt and short out over time. It took my 70 amp 8 years to cook them. There is no perwarning except the smeel of burning and by this time it's too late. There is a couple of threads on here about switching over and SW gauges sell a cobra looking gauge. You can paint the indicator all white to remove the color. Ps I love torque motors, just make sure the drivetrain is up to the torque loads, this means the trans and rear diff. Rick L.
CVFracing I think sells single pulleys. Match the water pump to the crankshaft. I want to say they should be about 5" diameter. Just might need the next surp belt larger to work. The belt length is the end numbers on it in Metric. Any parts store should be able to hook you up.
Al the pictures make the pulleys look different diameters. Measure them for size. As long a the crank and water pump pulley are the same diameter, run it. IF you have a over heating problem, we will deal with it at that time.
