Default Hot M62

How hot should this thing get? I just touched mine and it felt burning hot after a moment of laying my hand on it. I don't remember the old one doing this. This was following a 45 mile drive

When I got to work this morning, my SC was 140 average (temperature taken at 6 different spots). Ambient temp was 55. Keep in mind I have a couple extra things to keep it cooler.

2000SilverBullet has temperature data from our Superchargers at Woodburn for the last 2 years. PM him a link to this topic.

Haro, yours will run cooler. You're not spinning as fast as us.

Yes 140 F is normal. That is hot to the touch but not unbearable. When you can't hold your hand on it the temp will be about 160 F. This temp is common after making boost in hot summer temps.

Now you can see why we need intercooling. Imagine running a NA 455 engine with 200 F intake air.

At Woodburn I measured the temps of some S1 SC'* and got readings after a run as high as 175 F.

Don't forget that when the supercharger creates boost the temps can be more than 200 F

150+ degrees will feel hot to the touch. If you engine is a good 190 degrees, then with the supercharger making boost it might actually be hotter than that. So while your blower feels really hot its really about the same temp as the engine. Its not abnormal by any means.

On a side note, after an hour+ drive in the GTP with a 2.55" pulley the blower is cool to the touch. The I/C bottom half is plastic so it doesn't transfer heat from the engine to the blower as easily, plus the blower is ported. Doing this same type of thing to the M62 seems like it would certainly help with the heat. Maybe get a phenolic spacer between the blower and intake.

I'm not saying go buy one, make one. Getting stuff like that machined is not that difficult.
