Blown engines running meth - Page 4

ninjaboy76 · 03-21-2007, 07:20 PM

Even if you monitor it with everything under the sun, it only takes a few knock counts to blow your motor. At the rate of speed in which a motor is rotating, you most likely would not catch in time to save your motor. 22 psi is most likely to much for pump, but it all depends on the octane of gas you are running. There are some injection systems out there that offer safeguards. It might be worth looking into one of those systems if you are really wanting to do injection, but to me it still isn't worth it. I can also tell you from experience that the UTEC my retard timing if knock is detected, but it is very slow at reacting to it. I had the UTEC on my 03 WRX and I remember it retarding timing a few times, but it wasn't fast enough for me to not notice the rattle of beebees in a can that was coming from my motor knocking. This was when the first UTEC came out so I'm sure its improved, but most tuners prefer an ecu reflash over a piggyback anyday of the week.

I thought I would add this...

93 octane...
22 to 24 psi...
Meth injection...
over 400whp...
At almost 36,000 on stock engine...
Daily driver...

Meth doesn't kill motors.... Tunes do....

Time & time again I see a story about how this or that "killed my motor", METH does not destroy your motor when tuned properly. In fact it can save you from detonation, which is probably the #1 killer of our motors.
NinjaBoy is a perfect example of a tune destroying a motor.

DON'T SKIMP on the tune! Make sure it's right on. If that means going back 2,3,4 times, then do it. Get Street Tuner, if nothing else to become familiar with how the ECU works and why.

If your going to create an STi that produces over 400WHP, you better be very aware of how the car is running. Get all the proper gauges, keep your eye on everything. But most of all, listen & feel what the car is doing ALL THE TIME. If it does not feel right....do something about it! Or your going to have a broken ring land, a hole in your piston, or a broken rod.
I can tell if my car is running lean without looking at the AFR gauge.
Check your oil every few days, look at the oil catch cans & see whats inside, etc, etc..

You can't just drive a 400WHP STi and not be "in touch" with what the car is doing.

Yep...right on, right on.

Meth is not an issue, as it evaporates so fast and is burned so fast that there is NO corrosion to engine parts from it. The problem comes from when there is TOO MUCH sprayed and/or the tune is not right.

It's been used since WWII. It's not the problem.

Be good,

What happens if you have a higher HP setup (e.g. your alky nozzle is bigger)
and you hit the test button at a traffic light. But revs are up slightly.

Is it burned up fast then?

I think mine was either too much power for the stock rods, bad gas, water in the tank or the vacum hose popped off. We suspect all of them because of what we've seen.

I've got 36,000 miles on my 2005 STI.

SZ49 with methanol injection at 22-23 psi making about 410 whp and 440 wtq.
No problems yet. I've had my car modded for 20,000 miles. No increased oil consumption. No leaking at all. Runs smooth and crisp. Maybe I won the mod your car and it runs well lottery. Of course, my luck and the car will suffer some catastrophic failure soon. I continue to make offerings to the subaru gods for their favor and my gratitude.
