I read the sticky.

But for a pure street use only car, 427ci + S91, how do you go about making the decision to use it or not? Warm weather at sea level.


Could possibly be a 403-408ci too.

IATs would be a good start, if they're too high, spray some meth.

So are you saying that you should first built it and get it running, then use a meth kit if your IAT's are too hot?

Why, sometimes IAT's are hot and sometimes they are cooler and a car wouldn't need meth?

It all depends on the application. With a high boost it makes it safer with meth. You could roll with a boost referenced meth injection so its not on all the time. I would think the main factor would be how much boost you want to run.

28psi, full race gas.

If its just a safety measure that can ultimately save your engine it seems like a no-brainer to spend the $300-$500 for the system.

That has been my take on meth, safety device. Like you said for $300 piece of mind on a 6k engine its a no brainer. Detonation would be killer at 28psi and a crap load of rpms.

The best way of determining which system is right for your vehicles engine and application is by evaluating key factors for each. Additionally, it’s important to have a understanding of the engines current level of severity for which detonation may occur or is already occurring. Listed below are several key factors which we use to determine which system is right for your application.

Factors for determining the right water methanol injection system for your application are:

• Whether it’s naturally aspirated or forced induction

• The type supercharger or turbocharger being used

• Whether it’s equipped with an intercooler or non-intercooled

• Level of boost produced at peak rpm

• Engines current compression ratio

• Type fuel being used. i.e., pump gas, racing fuel, diesel, etc.

• Engines current tune. If ignition timing retard is required to avoid detonation or if the engine must be run excessively rich to avoid detonation

• Type driving/application. i.e., street, towing, drag racing, marine use, etc.

• Available space for mounting the additional container and pump when separate

Certainly there are other factors that can also be considered. However, knowing these main key factors listed above will ultimately help determine which system is right for your application. Lets begin discussing each of these factors and why they matter.
