Six tests were done, too much info to try and fill here without a chart capability...

How bout a PRICE ....how much did this bad boy cost ya?

Dyno sheet added, had to do some contrast/brightness adjustments and edited out my shoe-print

Cost me ~130 IIRC, on sale and "lightly used" - probably just open box

Looks like its about 200$, but a thrifty person could get it cheaper
I e-mailed powermaster and asked what made it so special versus regular denso's, I will try to drum up those conversations

Hello, I am interested in purchasing a new starter and found out about the 9050 model. Looked around for information but not much was available. The torque for OEM Mistubishi and Denso starters do not list their torque, but do list power rating. The Denso is rated for the same 2.5KW as the Powermaster 9050.

Are there any real differences?

The accuracy of the rating and quality of parts is the big difference. I can tell you that the Powermaster starter is very thoroughly dyno tested and proven to surpass our advertised torque rating.

All in all, I've been very happy with my starter. I cannot say if there are any internal differences, there were some minor differences outside but I can't find any before pics

Got a PowerMaster Alternator IIRC and it's a HOT ROD 250 amps...nice products they make!
