No it doesnt seem like more than meth.. This is EXACTLY what i have seen on 20 motors..

The piston was wrecked because it cracked.. The reason it cracked is because of the meth.. He had been driving on cracked pistons for who knows how long..

If the nozzle was clogged it wouldnt do it to just cyl 1 which is furthest from the nozzle and doesnt see the meth like cyl #4..

The fact remains.. 90% of blown Evo Motors we see ALL HAVE METH.. Including an Evo X we just got.. And go figure Cyl#1 was the only wet one.. The pistons didnt crack but cyl1 has 80 compression..

 

Thats the problem, this happens because the meth system fails for some reason and leaves the owner high and dry. Most failsafes cant react fast enough at high boost, high timing, and extremely lean AFRs when the meth suddenly kicks off. I am assuming that happened prior to the car going to AWD at least a few times.

Interesting to point blame on meth, but was the owner : (1) logging knock (doubt it), (2) did the owner have knock kill boost feature (tephra v5 - v7), and (3) what AFRs was the car tuned at prior to the failure ? I agree that ideally each cylinder would get the same amount of fuel (direct port injection), but can't understand how this could not have been caught with the proper failsafes.....

 

You are 100% right however the fact remains this stuff happens 90% less on motors without the meth.. There is nobody who will ever convince me its a coincidence that everytime a guy calls and says his motor is blown and i ask " do you have meth? " and he says " yeah but the meth didnt cause it" that it wasnt the meth..

Sure Poor tuning along with meth leads to blown motors but if there is NO METH on the car and you have poor tuning, bad gas, or anything its MORE LIKELY to survive then it is with METH on the car.. Period..

That oxygen is bound and unavailable for combustion. If it were available, H2O injection would behave like a huge shot of nitrous.


The two largest drawbacks are the fact that MeOH is less volatile than gasoline (it doesn't evaporate as quickly), and it converts a dry flow manifold to a wet flow system - a purpose for which it is not designed and probably not very efficient in that capacity.

At any rate, this piston was beaten to death with detonation well before it was delivered to Mike. One can only guess what was happening prior to his receiving the car, and for how long.

 

Im not single handedly blaming the meth im simply trying to help make the community aware of the risks that go along with it..

It has an AEM in it..

Im going to say once again its my opinion that the Meth caused it because unlike the other poorly tuned AEM car we had last month that blew up this one has 1 piston cracked not all 4.. and by chance its cyl #1 go figure.. the METH Killer..

wow well so much for meth on my car.....thanks mike
why dont you post this **** on highboost?

 

Here are some pics of another from last month with all Pistons cracked from poor tuning and once again the car by coincidence HAS METH.. LOL

 

I should copy it over there too.. Im spread so thin on forums for several cars i forget to post there too.. Thanks!!

Mike

 

but when it kicks in the feeling is like no other

 

Yeah and when the car is set up properly like on E85 you dont wait for anything to kick in and its always on.. And E85 feels like no other IMO..

Mike

 

Could the meth be cooling to tops of the pistons to much and making them crack from temp changes?

 

Hey listen bud not everyone is so fortunate to have an E85 pump every 50 feet, in NJ we have one place that apparently sells it and thats just not doable

 

No that isnt the case.. Not to mention it all goes back to the same story its ONLY cyl #1 the cylinder that sees the very least amount of meth..

Mike

 

Time to get my borescope out to check my pistons. If I see this then I will switch to E85
