I have built many cars but never used meth. Are there safety features in the tune and the unit if there is a failure in the unit?

You can set it up to where the IAT sensors will work as your safety net by repositioning them immediately after the meth and if they fail the car will see much higher IAT numbers than normal and retard timing.

Thanks for the response. I wonder if the guys that already had theirs installed and tuned took the precautions.

Forgot to ask what kit are most going with and where did you get it?

I was really hoping to do my mods this year, but had to replace our HVAC last week. I still want to get my ducks in a row see which route is best. I have moderate goals of 700-750rwhp.

Im not sure how they work on a ZL1 but living here in Florida and battling some high IAT's I inquired about using it as well. My tuner is not a fan and prefers to tune the car safely on pump gas, adjust the timing rather than depend on a Meth system. I believe the potential damage would happen quicker than the tune could adjust if the system suddenly failed. i.e. Meth pump dies, the IAT's skyrocket and the tune cannot react fast enough to prevent engine knock and potential damage.

I have researched this question for months. It’s an awesome power adder and the benefit is great but there is always that what if it fails question. It only takes one moment to lose big!

I am now leaning to E85 for added power but will have to research other ways to increase cooling. I have a 9.17 lower pulley now so I know I’m heating up the SC a bit more. I do 1/4 mile runs only and I let the car cool down at least 45min between runs. Currently I don’t feel much loss in power as my last 4 runs have been between 128-129mph and I’m more fighting traction as best 60’ is 1.86. I’m currently looking at expansion tanks in the hopes that could be better option.

My Alkycontrol methanol kit was installed with 2 LEDs in the driver side air duct.
A green light shows the system is working as it should.
A red light indicates a problem or the tank needs refilling.

This is not a perfect solution. But it is what AMP typically installs.

Your goals are obtainable with bolt ons with 93 octane. We regularly push cars out in that range with our stage 2 bolt on package. That being said we can add a meth kit to that and add another 50-75hp. Most kits today will let you know when you are low and out of meth but it is crucial to keep it filled.

Yes. My shop re-positioned the IAT sensor. I'm running the Alky Control system. I just looked at a few of my datalogs from the track. My IATs start at about 120 by the end of the 1st-2nd shift I'm at 90, 2-3 I'm at 66, 3-4 I'm at 55. Finished at 52.

I eliminated mine after losing a motor.

Since i want to do a cam swap when i do my mods, maybe it would be safer to go e85 and skip the meth

This is a highly debated discussion and all that has been written is factual. Meth has made a big insurgence over the last 6 years much in part because of the Direct Injected engines anemic fuel systems as supplied. Meth has always been used as a cooling agent and octane supplement. As it would be; if you spray enough it can also be a fuel volume supplement. This is what we have needed to do when surpassing the factory fuel systems capability. The the cooling and octane become a bonus. The other options are supplement (port fuel systems) or large DI injectors/pumps..

As a few eluded to; if your creative with the IAT spark retard table you can effectively build in a failsafe. If the motor can take "X" timing with the meth and the IAT's under meth don't ever reach a specific temp range; we can set the table to pull an appropriate amount of time if the temps reach this range without the meth... Of course sensor location and response time to the sensor can be a factor. In the past on big builds we would break out the IAT function from its stock location but on a Positive Displacement supercharger it needs to be where the compressed (heated air) is. On a centrifugal blower we would move it into the charge pipe.

The other issue is how much meth. We run 100% meth since we use the meth as a supplement fuel source where needed. Many times you'll see a 50/50 mix. This is because the water has a lower vaporization of heat (its ability to evaporate). This allows the meth to carry further in the path the combustion chamber as opposed to evaporating before it gets these. Also water has some heat absorption capabilities. However using it as a fuel source you need full concentration; as the meth holds BTU's of energy.

The other benefit we see from meth on DI engines is the ability to cool the intake valve. Since a DI motor injects fuel in the chamber (below the intake valve) we don't get the benefit a port fuel motor used to get. This cooling can contribute to producing more torque.

Food for thought and hopefully debunks some myths..

Thanks for the info. Your place is one of 3 i am considering doing the work on my car. I have a place near me that does a lot of the Corvette guys, but i haven't talked to them. The third shop is out of state(midwest). I prefer in state in case I have an issue. As stated, goals are 700-750rwhp. Needs to be dependable and deal with the Florida Humidity and Heat!

Well please let us know if you need assistance. This is all we do and have been doing it a long time.

FYI - Meth is hard on the bearing seals of the supercharger rotors. The tolerances are tight so when the bearings start to fail the rotors will contact the body and then your engine is ingesting metal shavings.The longer they run the worse it gets! Ask Kong, Jokerz and other rebuilders and porters because they will confirm that this happens.
