Driving Your Accessories with the KRC Chevrolet Crate Engine Kit

Building a good circle track engine involves much more than bolting together a good set of rotating components, slapping a great set of heads and a carb onto it, and heading out to the track. Engine driven accessories like the water pump, power steering pump, and alternator can be the difference between winning or fighting an uncontrollable car with electrical failure that overheats and blows up. Serious thought and planning needs to go into building an effective front pulley drive system. Thinking about machining every spacer and bracket and playing with mounting brackets for hours on end to get the pulley alignment correct makes us break out into a cold sweat. So, we went to the experts in front drive systems, KRC Power Steering, to help us dial in our accessory drives.

The Company

KRC has been producing front drive kits and parts for years, and they are famous for taking the headache away from car builders that are trying to figure out how to power their engine driven accessories. KRC built a solid reputation with their power steering pump systems and have branched out from there. Located in the heart of stock car racing, Kennesaw, Georgia, these folks have seen just about every type of car conjured up for dirt track racing. The Chevrolet engine kits are by far the most popular, and that’s the KRC kit that we bought for our street stock project car.

These are just a few of the options that a race car builder has to consider when putting the car together. While it may seem innocent enough, there are some big time repercussions if the builder makes poor choices. Power steering failure, electrical failure, and cooling problems can all lead to a destroyed engine and can be traced to poor engine accessory drive engineering.

Our Choice for the SBC Street Stock Engine

The small block Chevy 350 engine in our project car is a vintage early ‘70s four bolt main truck engine. And as such, it came stock with vee belts and vee belt pulleys. Vee belts were the standard drive belt since they were invented in 1917 by John Gates of the Gates Rubber Company. The biggest drawback to the vee belt was that the pulleys on the accessories driven by the vee belt needed to be large enough to have a deep V groove in order to “sit” without twisting. Ford Motor Company began using a serpentine belt, developed by Jim Vance (also of the Gates Rubber Company), for use on the 1979 Mustangs. The serpentine belts have proven to be more efficient than the traditional vee belts because a single serpentine belt can drive all the accessories that had previously required multiple vee belts. Using a single wider belt also meant that the belt could be put under higher tension without stretching. Higher tension on the belts reduces both belt slip and load on the engine by allowing the use of lower ratio pulleys. Knowing the advantages of the serpentine belt drives, this was an easy choice for us. Our previous issues with throwing vee belts under racing conditions had been well documented, and we were not about to go through the same heartbreak again.
