I have a question referring to meth injection kit. I'm gonna install a kit on my 6.2l corvette base model c6 I want suggestions on what kit to use an whats good.

 

For an out-of-the-box kit I'd purchase an Alky Control kit. I saw Juiced motorsports has a thread (somewhere on here) offering a discount code.
AC has excellent customer service as well if you have any questions.

 

Waste of time if motor is not on boost. Hence meth is 50% methanol, and 50% distilled water. When on boost, you need the meth to increase the octane of the pump fuel to prevent detonation, while the other 50% water being sprayed into the motor helps to cool the motor down so you don't get heat soak from the hot compressed air. Also, only time you need the meth/water, is when the motor is on boost.

If you have raised the compression in your N/A motor that stock pump petro is not high enough octane, then you need the higher octane fuel all the time, and time to switch the car over to E85 instead. Hence E-86 has an octane rating of 108.

And to back it up even father, the LS3 has lower compression than the LS2 and LS7 that need 93 octane fuel to run their best, while your LS3 will run it best on 91 octane fuel isntead. So your wasting your time with meth kit on a stock LS3 motor, since you may only pick up a few HP with a meth kit at best, over the power that the car will make on 91 octane isntead. Hence meth kit and tune will run you just over $1k, at best mixing your own meth fluid, still at around $6 a gallon,and to only pick up say 8hp at most, total waste of time isntead.

So to sum it up, motor only need an octane rating of so high to start with (91 in your stock LS3 case), and adding higher octane fuel to the engine beyond what is needs, is not going to increase power isntead. Truth is, the power you would pick up from a meth kit on stock motor, has nothing to do with the meth in the mix, but really comes down to the water being injected alone. Hence water turns to steam on the burn stroke to increase expansion in the cylinder, and helps the down stroke to produce the few more HP power instead.

 

I’ll agree on this pretty much but a lot of us run straight methanol.

 

My vette is currently running a v3 vortech supercharger also.

 

Then yes, you need a meth kit.

 

What is a good brand to get besides alky an snow.?

 

AIS (alcohol injection systems) also known as ProMeth. They have a real fuel cell that is designed to fit our passenger side cubby and use real stainless fuel lines unlike some others that use window washer reservoir for a fuel cell along with plastic fuel lines

 

Which would be the best one currently tuned on 93
