Just curious as to how many people have detonated or blown their motor while using either methanol or water injection? I've been doing some searching and I haven't found one yet, but that doesn't mean it hasn't happened.

If you have can you explain the cause and what type of driving you were doing?

Thanks,

I blew my engine while i was racing on track but that was because i forgot to top up.
while it was topped up, i never had a hint of knock or det. this was with a 50/50 mix.

 

Thanks for the reply. Sorry to hear that you blew your motor, but it's good to hear that it was while the AI may not have been flowing.

 

Oh it was about 5 years ago! I now have a level indicator and larger tank with sump

 

Have you had any blown motor issues since while AI was working?

 

Nope, all good!

 

The only way AI would (indirectly) cause the loss of a engine is if you tune with it. I think most don't. It's only added for additional safety and/or cooling.

 

VERY easy to blow yer engine with AI. Just up the boost or get a spike.

 

That sounds more like a tuning issue if you were to tune at the limits with 'X' amount of AI and then you went out of those boundaries.

 

Where do you guys put your pumps, in the bay or in the cabin?

 

I have actually blown an engine or two on AI.
Wasn't because of the AI tho!

 

Tuning to the limits with a bandaid (ai) is risky. Yes you can do it and have great results if done correctly and tuned correctly. I have done this for many years but if you are tuning on the limit with AI and it runs out, stops working, or not enough then yes you will blow it. Having failsafes built into your EMS is the only real way to do it safely. But even at that something can still fail. The absolute best way is to tune without AI and then use AI to help relieve stress. Or if you want to go to the limits then run race gas or E85 and with a good tuner and proper setup you will never have to worry ever again.
I did Dent a rear rotor on my rew last fall on 35psi on 93pump and 50/50 AI. Motor ran fine when driving but had tad rough idle. But who really needs 35psi in a street car?

 

What kinder power did you make at 35psi?

 

Thanks for the replies. The responses are pretty reassuring for my upcoming project. My plan was to make as much power as my tuner was comfortable with on pump gas then just add my AI on top of that. Seems like that method is pretty safe.

 

Wish I knew. But when I would ease into boost in 5th gear traction was lost . Id say around 700hp It was impressive but never again will I run those power levels on the street
