Curious if anyone here has any prior experience with mini-starters. These are high torque, geared starter motors primarily for high performance street or strip cars.
BBC 454 punched out 0.060 with stock stroke, gapless rings, performance camshaft running around 12:1 static compression. Dynamic compression is higher due to amount of ignition advance. Stock starters have always struggled to start this engine even when cold. Verified no spring bind or other mechanical issues. When heat soaked, forgetaboutit. Running 1000 CCA battery with 2 ft of 1/0 cable on both feeds.
Looking at getting a mini-starter. Figure minimum of 180 ft/lb torque. Two choices stand out from Powermaster; the Master Torque or Power Max Plus for BBC w/168 tooth flexplate and staggered mount.
Anyone have any experience with Hitachi style v Denso form factors? Which do you prefer and why?
Both produce same torque @ 180 ftlb. However, one is geared at 3.7:1 and the other is 3.25:1. Not big difference. However, one is rated @ 1.8 HP (1.4kW) and the other is 2.5 HP (1.8kW). I don’t want to load the battery more than necessary so does it make any sense to choose the higher power rating if they have the same torque rating?
