Don't let this scare you we have been running Water meth systems for over 10 years, without Issue.

The Pictures above are an EXTREME CASE and when they answer the questions I posted I think all will be alot more comfortable.

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.

Just in case they forgot.

We havent forgotten... just been busy -- and trying to get the correct information.

The best info that I can give you at this time is that it is an Eaton 1900 factory blower off of a CTS-V

The finish on the rotors is called abradable, basically a self-clearancing powdercoat that is designed to wear down slightly to adjust to to tolerances. This coating is the modern version of the teflon strips the old 71 series roots blowers ran to maintain a "seal" between the rotor and the housing.

Looking forward to your answers.

No I've installed 2 Meth kits on Maggie Blower setups. Have not heard issues of loss of boost, or coating wear due to the meth injection, I'm not expecting it as well. I believe these pics on 1st page is an extreme case, and most likely used with 100% meth injection VS a H20/Meth combo.

Most meth kits I've installed were on Centrifugal Blowers like Procharger/Vortech systems, which installed (is after the compressor), so you would never run into this issue anyway.

Don't let this scare you too much guys. Meth injection is a proven concept, and has been around for nearly 100 years, installed properly and monitored, this is a good way to add safety and power, to your F.I. engines.

Im sure you guys know that the mustang guys have been injecting pre-blower for what seems like forever.

Now I am curious if a snow meth system would mess up a E-force setup? Anyone?

I want something that is fool proof and low maintenance. I want a trunk mounted tank. I have thd Maggie with 3.6 pulley, long tubes with high flow cats, boost a pump. Put down 536 rwhp last dyno. I want something I can run with pump gas. I don't wanna hear from the manufacturers because they tend to be a little biased (please dont get angry)......please educate me which way to go.

well....IMHO...you don't need it (meth) and it is a pain in the R-ss to maintain.

If you go with any meth system, regardless of manufacturer, the systems only adds power if you tune for them. That is to say, any properly designed system should be able to take a 536 rwhp Maggie up 50 hp with easy. But is it safer?

Safer than what? You just added 50 HP so if you are asking if 536rwhp is as safe or safe than say 586 with the Meth then NO.

So here is my take...Meth makes more power - no question. However, if you just added a meth inj system to your car "as tuned" it will not make more power. In fact, it can and should loose power. Why? The water meth puts out your existing flame in the combustion chamber. It makes the car run rich too

The extra power gained by meth injection comes from adding more timing and leaning out the fuel flow.

So you just got your meth system and had it installed and tuned - what did they do? chances are they gave you 5 or 6 more degrees of timing at WOT and full boost. Then for good measure they leaned it out just a tab to make up for the meth now being pumped in.

Cool, now your car runs faster but YOU ARE MARRIED to the system. If you run out of meth, you can't go Wide Open under boost until you add the go go juice. For some it is the price you pay for the extra power. but I guess teh old lady in me says once the thrill is gone... I would trade the lower power number for the less hassle

Now with all that said - We have had great luck with Cooling Mist and Snow for our customers. Also if you are at 535 you can safely go to 600 on pump gas before you need the the meth to compensate to the low octane

NOPE they set the Grenade down with the Pin out and ran like Hell.

Now that's funny.

You would remove it, install a centri and be good to go

Sorry, I disagree slightly here. On nearly all FI setups, the add of a small shot of Meth to cool down the charge, does add HP and safety. Does it maximize your HP potential by running Meth, no, in order to do that you need to add timing and tune for the meth it as you mentioned. Also does not mean you spray too much meth, as that could cause a loss in power. It's about the proper combo.

:P

I could make something up just to give an answer, but I would rather not. Being that I never saw the blower in person & I think that the owner denied running ANY meth through it, its not exactly easy for these answers to be produced...
