So has there been any dynos yet for 2010 Camaro SS before and after coolingmist..
I know on my old car my kit made like 50HP

we will be testing one this week..the coolingmist it working well on the street cant wait to turn this car up!

How do you guys inject after the blower? I wonder if I can both before and after. If one injection point is good, two just has to be great! Maybe I should ask Ted about this and see how he reacts.

Here is a little map that shows some of the features of CMGS.

took some new pictures of the CMGS and the CMGS kit this weekend.

I know there have been arguments in the past on other forums that methanol can damage blower rotors that are coated with teflon... Is that a thing of the past? Are new rotors not at risk to damage? Just curious.

Have you guys got a way to inject after a TVS2300 on an LS3?

I'm pretty sure that with the way the lower manifold is set up, it would be extremely difficult and very expensive if at all possible.

yeah.. I don't pretend to be a machinist but I don't see an easy way to do it without removing the intake....

and at that point it just isn't cost effective, just to get in after the supercharger.

I'm thinking I will just go with the precharge injection.

I have heard this, too. Reactions with the metals/materials inside the motor.

What, if any, effect does methanol/water injection have on the innards of the engine/supercharger? If I were to supercharge my car, I'd want this system installed -- but not at the expense of longevity.

Also, this may have been answered earlier...but I was unclear when I read through the thread; if I'm driving a supercharged car as a Daily Driver...I don't want the methanol to inject under those conditions. Is that what the minimum setting is for? To set a cutoff for injection?

That is how I understand it. and there are multiple triggers. I think you can trigger it from Boost or temp?

Yep. You only want it coming on under boost and/or severe boost conditions. Triggering off of boost AND temp (voltage) would be a great combo... Just don't put the sensor under GTA's drivers seat.

Okay. Then in that case...

"temp"...= IAT?

Because triggering off of boost only on a maggie is pointless. It makes the same psi all throughout the powerband. If that's the case, then this is sorted out for the most part in my mind...I'd just like to hear about the effect Meth/water has on the engine over time.

Hey I'm gonna give you a call later.

Temp can be IAT, coolant temp or EGT.

Primarily, boost is the most important. The boost you refer to is only the same psi throughout the powerband at WOT. Slightly less throttle is vacuum or low boost - pump gas friendly, hence the need for a boost sensor. Meth injection is only needed when you push the boost beyond "max pump gas" cylinder pressure. A secondary sensor would be IAT for instantaneous change, but coolant/oil temp will give a better indicator of combustion temp.

Wear: When set up properly, the time and amount used is so infrequent there is no additional wear.

Personal opinion - take it FWIW - do NOT use a meth/water system to increase the output of your engine for everyday driving. For track driving or wild weekend cruising, most definitely. I used a Spearco meth/water injection for years on a very high compression engine and never had issues. A good reference source for further info on meth/water injection is David Vizard. He is a technical author who did/does a lot of freelance work for many high performance magazines.
