125,000 with no problems...but id still like a way to get heat away from it...but it probably won;t happy with out reclocation from the head.
being so close to the engine theres no good way to get the heat away form hit....Oh and a KKM is properly efective with a heat sheild.....with out that, you would be just sucking in hot air,(heat soak) which can cause low end performance loss. High end you do not need to worrie as much becuase your getting the flowing air while in motion.

Something that could help was discussed recently: Cutting cover over IMRCLike Lupe says, unless it's relocated away from the engine, heat sinks and cutting the cover will only be of marginal help. I guess every little bit helps though.

if you should decided to relocate it, mounting it to the underside of the battery tray is quite convenient.

The IMRC has a 2N6045 Transistor in it, you know electronics at all, that Transistor is meant to resist heat, im talking well over 1000F of heat, The though of relocating it, or venting it for heat period is a 100% wasting of time. Transistor takes voltage and multiplies it ,same was as a car amp works , doing such a thing makes it hot , VERY HOT ..so like i said ...doing anthing with the IMRC is really worthless IF you know electronics at all .

wow - I had no idea that it was one transistor that was the single point of heat related failure in the IMRC.
Here I was stupidly assuming that it was the BIG ELECTRIC MOTOR under the cover was what was being affected by the extreme heat

Nope , transistor will go out before that will , take out the electric motor and look at the windings . Educate yourself son

Gee dad, I thought that's what my degree in mechanical engineering had done 
Point is - the failure rate of IMRC from heat is a HUGE issue. If you'd bothered to search around you'd see tens to maybe even hundreds of posts about it. Many times near dead IMRC's can be reliably used after removing the heat catcher or relocating them off the valve cover. It's been a proven fix. But if you say it's the transistor in an all knowing tone obviously we're all just dumb! Oh, and I've looked at 2 different motors thanks - the 1st dead one is currently back in use in a friends car located under his battery tray.

But transistors aren't affected by heat
The motor is pulling current in a stalled state when the IMRC is open - ie there is no back-EMF to limit current draw. On top of that it operates in a condition that is hot enough to burn the crap out of human flesh. My vote is still on the motor, but being M.E. I will always look at mechanical failures before electrical. Seening as how a "dead" IMRC can still function normally when cooled - I would think that points in the direction of a motor overheat problem over a burned out transistor that would kill the IMRC permantely, right?

Uncalled for and unnecessary. Keep it a discussion, not a pissing contest.
