tuners' advice wanted.....meth injection ...should i or not? - Page 2 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

This is an extreme example of your blower on meth.

Because our rotors are zero clearance, the rotor finish is very important.

As far as how you should go about meth injection, I've got nothing. I suggest homework & research. Just like modding your car while under factory warranty, you may need to pay to play... same goes for the supercharger. Just because it voids your supercharger warranty doesnt mean you will gain no benefit from it. But, beware that the benefit may come with a cost.

What Model Supercharger?
What vehicle was this on?
How Many Miles?
How Much Blower Overspeed was involved?
Did the supercharger Fail as a Result of the coating coming Off? The rotors appear to be fine otherwise.
Was it sprayed with Straight Meth or Water Meth?
What is the Coating on the rotors made of?

Does this Apply to Current Production Magnachargers?

I would think that Gasoline would have the same affect on this particular coating since it has Ethanol in it if it were Carburated.

Probably a TVS. I'm sure it's not an early MP112. I don't think even the MP112HH/MP122 rotors have that much twist. One thing to consider is that even though you may lose a little coating, the fluid injected is going to take up a bit of the extra clearance

The only time you need a good seal is when you're under boost. My Snow system starts coming in at 4psi and is full bore at 6psi. I probably have 60K+ on that MP122. I've been spinning the snot out of it from day one. Started with a 2.8" pulley and more recently a 2.6".

Great questions, you beat me to it. Curious on Jessika@Magnacharger's answer

Slowhawk · 09-28-2010, 05:02 PM

Ted, It happens to alot of the Magnachargers with anykind of methenol solution.Seen alot of those throughout the years.

I would figure since alot of people run methenol kit's now and the Magnacharger definitely benefit's from it that someone would come up with a coating that doesn't get affected by it.

Jessika · 09-28-2010, 06:11 PM

Since I don't have the answers to the questions, I passed this to Jon. Hes been buried in work today and says he will answer ASAP. He is the one that shot the pictures of the blower.
Sorry guys... but we will get you answered!

Hard coat anodizing or the proper PTFE coating is resistant to it. You have to tear it all apart and mask off, etc. and I'm sure void the warranty.

But I will tell you, methanol itself, is highly corrosive, and if it gets to a certain mixture of oxygen, water and meth, it will turn to acid and eat everything in its path. As long as the motor runs for a moment with the meth system off, this will not be a problem, but I've seen some systems that don't have check valves and during vacuum (idle, shut off, highway), it will suck the water/meth from the system and then when you shut the car off, it will sometimes eat chunks of material. So just make sure you run a check valve so you don't get any leakage.

wow this is eye popping, what about just straight water inj..i have of this before also

aet08 · 09-28-2010, 06:43 PM

do centrifugal blowers like vortech have this issue?

Yes it is. I put some in an aluminum cup for awhile to test. Alittle tap with a hammer and it shattered.

Not trying to scare anyone.I recently pulled apart a C5R 427ci we built 5 years ago.Ran 14lbs of boost from a procharger and went through an easy 20-30 gallons of 100% methenol. There was no damage to the aluminum parts of the motor and the pistons/valves looked new from the methenol.
We also always run check valves so it doesn't siphon. I'd say it's safe to everything except maybe the maggie rotors.

I was thinking about putting a Meth injection kit on my TVS-2300 until seeing this.......

I am not to sure now.....

Watching this close now....

Same here bro!! Will be watching to see what happens.

Meister@Torq · 09-28-2010, 10:20 PM

This is usually what happens when spraying methanol after the TB, directly at the rotors. The methanol mixture has not had time to atomize properly and is much more corrosive this way.

We suggest spraying before the TB (just after the mass air meter) to eliminate the possibility of this problem occurring.

Everyone is very worried about their warranty when using meth, however, everyone has forgotten that once your stock 3.8" pulley is changed for anything else (and I can guarantee there is hardly anyone left running this pulley), this will void your warranty.

Magnacharger, why not use a Methanol resistant coating? Your customers are basically demanding for it and I bet would pay an additional fee to know their blower is methanol safe.

To our consumers....we are working on 2-3 upgrades that will drastically reduce air charge temps and solve the issues of methanol getting anywhere near your rotors.
