| + | ==Introduction== | ||
| + | "Hi-torque" starters can mean a starter made with a gear reduction to add mechanical advantage, or it can mean a starter wound with an armature that delivers more torque than a "standard" starter. | ||
| + | ==OEM high torque starters== | ||
| + | Two part numbers for OEM starters from [http://www.sallee-chevrolet.com/Starters_And_Parts/index.cfm Sallee Chevrolet GMPP parts] are: | ||
| + | '''10455709'''- Gear reduction (GR) starter, as used on the 1988-'95 L-98 Corvette. | ||
| + | Technical Notes: Use with 12-3/4” outside diameter flywheel. Pre-LT1 engines require starter machine work. | ||
| − | [[ | + | [[File:10455702gm GR starter.jpg|thumb|left|400px|Part number 10455709 gear reduction starter for the 153 tooth flexplate/flywheel]] <br style="clear:both"/> |
| − | |||
| − | + | '''10465143'''- originally for Camaro Z28 with LT1 engine, so it would also have been pre-L31 Vortec era. The Sallee description calls it a GR starter, but it doesn't look like a GR starter, and [http://www.summitracing.com/parts/NAL-10465143 Summit] calls it an "inline" starter, as well- so the description may be wrong. | |

| − | + | It looks more like the small diameter permanent magnet starters that came around in the '90s. Costs about $350 from Summit as of mid-2012, no warranty, and it's listed some places as a reman, but this hasn't been verified. A better deal could likely be found elsewhere- like from a 'yard. | |

| − | Most also have universal mounting so they can be used with different flywheel sizes. | + | High torque starters are generally used on high performance engines. They are better at cranking over a high compression engine. They are usually less prone to heat soak. Most also have universal mounting so they can be used with different flywheel sizes, and they may have a feature that allows the solenoid to be "clocked" into a position that gives the best clearance. |
