Blown engines running meth - Page 2

B4RSTiwsnc · 03-20-2007, 05:34 PM

im getting nervous now with all this blown motor with meth talk, I am gonna drop the boost to 22psi and i believe that will be safe for now with a good tune.

I HAD an 04 STI with SZ55 setup plus supporting mods and SMC injection kit. I put down 412whp on a mustang dyno. AFRs were way rich. The motor didn't blow, but I had massive compression loss on all four cylinders, and massive oil consumption. I don't know any other way this could happen other than the meth / water mix flushed out my cylinderwalls. I won't be doing meth injection on my new ride.

According to who and what dyno is 400 whp safe? I was under this misconception for a long time and if I were to get another STI I wouldn't push is anywhere near 400whp. 350 whp would probably be a good number, but again...on what dyno? That changes things drastically.

topspeed has a lot of STi's in the 400's and 500's whp on stock blocks running meth injection kits.

My motor cracked the #4 ring lands and I did have meth injection, but I don't really think that the two are related, at least in my case.

And this is why I have to be content with my 350whp 93 octane sippin' 20G setup

There is just no way in hell I could foot the bill for a motor rebuild

jays05, how much boost were you running?

hmm, i always heard Doug was great with tuning at topspeed....

It just seems odd that the few in this thread that mentioned they have had major engine problems all were running methanol injection. Its a great power adder and safeguard but I think I will pass on injection on my daily driver. 375whp-400whp sounds reasonable with a good tune.

AwdMonsta and Ninjaboy76-How long (mileage) did you run your turbo/meth setup before you experienced issues?

Anywhere from 23-26psi. The car made 415whp @ 26psi on KTR's unmolested dyno dynamics, 200whp more than a stock STI makes there.

I think that the meth injection just delayed the inevitable...
