Meth Question

[Grizz]

I've been digging around the WWW but haven't found an answer yet...

Can you use meth kits to build boost faster?

Instead of applying meth at the higher rpm's, can you inject it earlier to help build boost, then continue through the rpm range with it still injecting?

Doesn't make sense... building boost will happen at certain rpm's, are you saying you'll reach that rpm faster basically youre assuming that meth will help you rev up quicker?

That's exactly what I meant. Is it safe to be applied earlier in acceleration, to help gain rpm's, to help build boost, then follow through with that injection as the boost comes on and peaks? Is it safe to be used in the lower rpm's to help speed up the motor? I have zero experience with meth systems.

Id think you could use it throughout entire powerband but i think the point here is its only practical if you are using the meth/water injection to cool down the intake charge at higher rpms when the turbo and engine is flowing hotter air. Maybe Im wrong. Wonder how it would work in combo with e85 or race fuel and lets say injecting the water/meth before the throttle body on each bi pipe. I know jhm made a nitrous/water/meth injection intake spacers, but from what i read they never made it to production because lack of interest and apparently only a few were made. On a fully built motor, stk or twin, having 6 separate injection locations for water/meth nitrous would be sick. my only worry is would it be dangerous because its being injected so close to intake valve? Not enough time to mix?

No, meth won't help boost, if anything it will delay it since charge and EGTs will be lower so there will be less energy driving turbos.

If you want more TQ and quicker boost on an engine, the only way to do it without otherwise altering hardware is to use nitrous oxide injection. That's it.

I always figured that since the charge air is cooler it would be more dense, you could move more air to spin the turbos. That and the fact that you can run a lot more timing.

There is a definite delay in meth starting spraying in any usable gear (2nd or 3rd) where it starts spraying when you're well into your top TQ/RPM numbers (thus already spooled up) and if you set it to start spraying too early, you will flood and bog down the engine.

This is the reality with 99% of meth systems installed in wanna be race cars, e.g. cheap systems triggered by boost level (sic!) or maf/IDC (better).

To accomplish what you're talking about, you'd need super-expensive constant pressure solenoid style of meth system that can squirt very precise amounts of meth, at any IDC, at same pressure and atomization level (1000psi systems and such). This just doesn't happen in sub 1k systems.

As a result of using soemthing like devil's own or snow, you have a meth injection system that delivers fairly constant (regardless of its duty-cycle value) amount of meth regardless of what is the trigger value at any moment. Thus you end up with the amount of meth that usually is dialed for mid-high RPMs (Whcih is fine since system needs time to build up pressure and flow, you're past this area in low gears before it starts really flowing) and below that it floods engine (if you were to accelerate in 5th or so), above it is simply insufficient to keep EGTs in check...

In addition to the above, you'd be spraying the meth all the time you'd even touch the gas pedal so it would be a pretty expensive proposition. You'd probably need a second gas tank hooked up under the tank just for meth!
