ummm... yeah. pieces of coating being pushed into the motor = not good for performance.

but without more info we dont even know what car the blower is from. it may not b a gen V blower

 

QUite possibly a very bad idea

Then ur blower heats up real bad...esp if ur bearings are shot...the the rotors expand and seize together stopping the motor and requiring u to wait 30 minutes before u can start it again...dont ask how i know...then u permanently lose boost cause ur rotors and housing are fucked

I was tuning coast down fueling reving to redline adn coating down and my blower overheated and seized up...meth woula saved me

 

Wut? thats from overspinning the blower. it has nothing to do with spraying before or after.

 

If u need meth for octane/cooler temps ur obviously running a small pulley which is over spinning the blower...meth would have prevented my failure

 

well that blower IS a Gen V M62 off of a 2006 Cobalt SS/SC. have been running water/meth for about 30,000kms. What does my post count have to do with any of my trustworthiness???? just before winter i dynoed my cobalt at 283hp and 232tq at the wheels. Also i have helped build a 2002 cavalier with a 3.1 V6 turbo in it that made 320 hp and about 280tq at the wheels. this cavalier has easily beaten a mustang that runs 12.6 at the track. both dynos were on a mustang dyno too........i will post the sheet if no one believes me. Just because i dont post on here lots means that i know nothing????????? As for giving no details i was in a rush and had to get to work. Quite a lot of responses in a couple hours. If you want more pics i could get you a lot more....that blower is off of my car. I am not trying to stir stuff up just showing what has happened to my blower. the meth i was running was "turbo Power" the blue stuff. about 60% meth. i have reason to believe that it was not the meth that ate the coating off of the rotors. I think it came from when i was at the dyno after doing 3 runs the car smelt like burnt plastic........probably the coating. A blower spinning upwards of 17,000rpm and high IAT2 temps probably did it. But who knows it could of been the meth also.

As for performance i dont think it hurt it at all.

 

More pics. or ban. lol. I wanna see all angles. and your meth set up.

 

I wouldn't say it's the meth...
A buddy I went to high school with has an after blower (tag style) meth kit on this GTP (Mind you that car has an M90).
Anyways, he's been running that for almost 3 years now...
And this fall when he had his blower polished and ported, there was no sign of rotor damage at all.

I'd say your damage is overspin 100%.
No offense, but you should really look at the blower spec sheet before modding and working the engine hard.

 

^^^^

Blah, i meant for more pics not the post above me!

 

Hi my names Will ive been clean for 5 years now

 

Wow... anyway..
I dunno that looks more like from bearing wear than meth,... as I said I've been running a 2.5 pulley and was spraying meth through the blower for 10,000 miles and absolutly no sign of wear whatsoever. the way the rotors themselves looked, seems more from contact with each other/housing caused that.

 

"after" the blower would not send meth through the blower....... therefore no meth reaches the rotors. ....

 

First off, I want to clarify that I wasn't trying to go off on anyone, and that there's no hard feelings. Second, the comment I made about post count is simple. Generally, the people who have posted technical info, have been around for awhile, and made quite a few posts helping people out. I'm on this board everyday, and when I see an unfamiliar name come in, I'm less likely to believe what they say vs the people who've been around alot longer. That's all I meant by that.

Now about the pics, that looks like damage NOT caused by the meth injection. Overspinning, bearings shot, too much heat, etc. What size pulley were you running?

 

They use windshield washer fluid, it doesnt have any soap in it and it is already pre-mixed w/ water & meth

 

2.8 pully witha custom tune with HP tuners. was gonna pull the blower apart anyway soon to port it and change the oil in it. i wonder what GM will say about this.......

 

I use a gallon on winter mix washerfluid and 2-3 bottles of heat (99% meth) just to up the meth ratio.

 

Dude there are different types of windshield washer fluid. You need to use the water/meth mixed ones. Looks like you used the bug and tar windshield washer fluid. Yea I know it cleans your windows wicked good but...as you witnessed...will eat your SC.

BTW I have a SC F/S

 

If your talking to me that is what i use, its a water meth mix only. Thats why its called winter mix. I add another 2-3 bottles of heat to add to the meth. I don't use the but and tar one.

 

cobra owners have been running it longer than you guys have and ive never heard of any problems. just a fluke

 

Exactly....
Why would you spray before the blower anyways?? ... the water/meth would have no affect on the already ambient air....
Spraying after though, the mixture has time to cool the air and work it's wonders...

 

Because spraying thru the blower not only cools teh blower but cools the air as its compressing preventing it from heating up in the first place. It also helps it disperse better in the air since it is in it longer

I see no harm from sparying before and feel it is more beneficial than spraying after

 

Do you realize how hot it gets inside that blower with a 2.5" pulley? Trust me, the mixture is evaporating just fine.

 

W3rd

exactly

Dan speaks the truth there people...

 

I have about 26k miles on my M62 running a 2.8 pulley and my rotors do not look at all like that.... There is one small leading edge with some coating gone and the rest looks fine.
