ProCharger Head Unit Temperature
ProCharger Head Unit Temperature Hey guys,
Have any of you on a F-Body or other wise ever noticed the temp of your blower after just normal driving or making a pass?
I was tinkering on the car yesterday. Car had been idling for a bit up to temp, drove it down the road about 2 miles. Come back and was going to change the crank pulley, placed my hand on the blower, and was socked at how hot it was! I could put my hand on it, but couldn't hold it there for more than like 5 sec or so. Didn't have my temp gun around or would have shot it to see what it was exactly.
It's a F1-A with a SDCE bracket set up running a 3.70 blower and 7.250 crank. So it's not being over spun. The drive I took I just eased down the road, didn't even get into boost. I can turn the blower by hand no problem with the belt off. Don't know about oil level, didn't get a chance to check it.
Just wondering if any one else has ever noticed this and if it's normal operation or if I need to start looking for an issue?
Appreciate any response!

it might make a difference where you are getting intake air. if its sucking from above the header it is getting hot air under the hood. that makes them pretty hot when cruising.
Just like stated above, it's aluminum, so it's a heat sync. You have the radiator right in front of it, so you will have 160-200 degree air blowing onto the blower. I bet you could pull the belt off the blower, and drive around, and it would still be just as hot.
This is one of the reasons that I put a meth/water nozzle going into my blower. It helps to pull some of the heat out of the head unit.

I do agree with you guys on the aluminium being the sync part. I guess I was just thinking the blower unit itself would stay cooler than it does. Especially just cruising down the block and back out of boost.
Alchemist, How much meth you throwing in front of the charger? Is that your only source of meth, or do you have another nozzle or two in front of the throttle body as well?

Did a f1r over spun by 1000 rpm. Used meth to cool intake charge. I also did a small shot in front of the blower about 4 inches away to help with cooling it. After a one mile run blower temps where about 100* + outlet temps where 87_91 degrees during the run
Touche, touche... 
Always good to keep some secrets!
Nice! What head unit and pulley combo you have planned?
This is the kind of info I was after. I always thought a small sniff of nitrous would help to keep the temps in check, and a lil bump in power too.

I wasn't trying to be shady, well, maybe a little, but I run Aquamist injection and they spec their nozzles based on orifice size, so I'm spraying a 0.3mm nozzle into the blower, and two 1.0mm nozzles post intercooler. I think I'm going to up the size going into the blower now that I'm pushing more boost.

There was a C5 procharged guy (i think) that ran a fan blowing cold air onto his SC. Reported a decent drop in head unit temps!
one questions would be what do Procharger say about heat? Maybe the heat is required to make the gear oil work correctly? Just guessing.
If not the case i wonder is a shroud and cold air feed (via a fan) would not help keep head unit temps down.

I got to thinking, if an alternator uses a fan to cool, why wouldn't something like a small fan built on the back of a drive pulley blow air over the Procharger-prob would take to big of one though
As for the oil temperature, I'm sure there's a specific reason they spec'd their own oil to be run in the unit, most likely based on the viscosity and shear forces at the operation temps. That or just another opportunity to make money, but I can't see them making a huge profit from it since it's not like you're going through much of it. I swapped my oil last year after only 1,100 miles on my unit, but will probably go for about 2,000 till I swap again.
