So, I know the methanol is eating the Teflon off my M62 rotors (one end is polished looking and the other still black, last time i looked..lol). This also makes the bores look really crappy in the SC (from running the trash around the bore).

Those of you running the TVS and methanol, how's the coating standing up? I'm gonna run it either way, it just hurts my feelings to do something destructive to a piece I just laid a big chunk of money down for.

Thanks!

I want to know as well, since I haven't hooked up my meth yet. Does anyone have real life facts about this?

 

subd as well

 

does the tvs even have a coating on the blades? i know some blowers don't even bother with it...

 

Yeah.. they've got a black coating on them

 

That is indeed what we are trying to figure out. What is it, and will it get worn away my methanol. Yes or no? Any vendors with some knowledge and not just vague speculations would definitely help!

 

 

yea they do. Area47 has been running meth on his car ever since he had the TVS and he runs a pretty strong mix. his doesnt have any problems.

 

The question is not will there be problems it's will meth eat away the coating.

Maybe no problems now, but will it eventually?

 

thats what im saying. he doesnt seem to have any problems with the coating being eatin away. and hes had the TVS on for quite awhile

 

More opinions needed! Not that I don't trust you but.... well your being vague. Have you seen the inside of his TVS since he has been on meth?

 

If meth isnt eating away at the m62 teflon rotors after people been spraying for years i doubt it will eat the tvs if it does you wont have the car long enough.

 

Soo whats the huge problem if it does eat away some paint?...

 

He just said it IS eating away his coating on his m62...

I'd say it's really no that big of a deal but it's def not a the best thing ever.
Spray after the blower?

 

It is eatting the coatting off of my m62.. :P

And even if it doesn't effect the efficiency of the blower very much to lose the coating. the particles are making thier way down to and clogging up the fins of the laminova cores, wouldn't you think?

 

The older Eaton blowers used larger tolerances in the blowers with a teflon coating on the rotors. The M62 in the Cobalt does not have teflon on the rotors. It's more of a powder coat and doesn't flake off like the old blowers used to. It is considered abradable, meaning it's meant to 'wear in' As Eaton has tightened tolerances and used coatings the efficiency of the blowers has improved, especially at higher boost levels.

Methanol injected before the blower will speed the loss of coating but it is a small issue with the current generation of blowers. It will not clog the IC cores. It is still recommended to spray methanol after the blower using a blower spacer plate over the TB spacer plate.

Zoomer, You're alright.

Thanks!

 

I didnt even know zzp had one of those damn........

 

Our info is pretty much the same, Just a few things to add. The older blowers 4th gen and down used an epoxy coating and to my knowledge there is no teflon in it. This coating was very resistant to fuels and is gray in color.

The 5th gen and tvs coating is an APC(abradable powder coating) that is graphite based, it is black in color and is not as resistant to fuels.

to finish this off, you should technically not run anything through the blower. It's designed to pump air and only air. Anything extra that you send through it(meth,water,n2o,gas, etc.) can and will void harrop's and eatons warranty.

Now I have and still will run meth,water,n2o,gas, etc. through the blowers as I have not had any problems doing so and neither have the masses.

 

No, you shouldn't. I believe the coating is just for noise reduction anyway. I could be wrong so don't quote me.

 

id be interested in knowing more about the after blower spacer for meth as I havent seen one person run it.

 

Does a s/c gasket need to be used with this?
Nice alternative to drilling into the IM to spray.

 

This is actually very easy to do when you are doing a dual pass install. all you need is the right drill and a 1/8 npt tap.

 

If it is not recommended to spray before the rotors, why hasnt someone made a IM spacer with nozzle taps? Seems like someone should get in on this and make some $ while serving the needs of the communmity.

 

Demand would be my guess. I'm just tapping into the intake before the TB.
