Torque is the fancy name of the game when it comes to kick starting power in a Porsche. Just as it takes corpus amount of torque to spin the car wheels and get a car in motion, it also takes some torque to crank over the engine. That is exactly where torque starter comes into the picture. Its main work is to crank over the engine. But there is much more into what this small component does than just cranking over the engine. Read on to learn more.
All components inside any Porsche engine generate friction that works against the starter. Compression also makes it hard for the starter to fire up. Note that high torque starters are designed for higher compression ratios. They are not really designed for use in slightly modified Porsche models. This means you can end up spending too much on torque that is way beyond what your model can handle. That explains why it is important to first consult your mechanic before fitting your Porsche with a torque starter.
Although a standard 200 pound torque starter will work just fine in any application, your small block engine will need just 160 pounds. This can be confusing to a person who knows little or nothing about how torque starters work. Two torque starters may sit by side and still have different specifications. This goes on to highlight how consulting an expert as already mentioned is always a smart move.
Gear Reduction Vs Direct Drive
It is hard not to mention a thing or two about the gear reduction vs gear drive dilemma anytime you talk about torque starters. That’s because they are the two main methods a torque starter can use to drive a ring gear of a flywheel or a flex plate.
Direct drive came first, which is why it is popular in old Porsche models. It features using a large, low speed motor to gently rotate the pinion gear in a 1:1 ratio. Gear reduction on the other hand is more or less the opposite. It uses faster motors to rotate pinion gears in approximately 1:4 ratio. This results in low power consumption and at the same time, high torque. As far as price is concerned, direct drive units are cheaper. Sizewise, gear reduction units are smaller, lighter and more importantly, efficient.
What To Do
Since early 1990s, OEMs have swiftly moved away from direct drive starters. They have embraced gear reduction torque starters for several reasons. Despite the fact that that reduction torque starters are more complex, they are also lighter, smaller and as already hinted, more efficient. They also tend to last for long. It gets even better with the fact that they are well suited for extremely cold weather conditions when the available cranking amperage from the car battery tends to drop. The best you can do is to replace your direct drive torque starter with a gear reduction torque starter.
Point To Note
Remember that reduction gear torque starter can be adaptable to different engine sizes. Some torque starters are actually open nose and can work well with ether big block or small block engines. That’s not all. They can also be easily inverted where necessary for extra clearance in applications that use oversized oil pans or where there is a header clearance problem.
