like the others have said and:
add a water meth system and monitor your charge intake temps.
Keep a strong ignition system.
dont run oil less than a viscosity of 10w/40 and make sure the oil has a high level of ZDDP.
keep your coolant temps under control. 200F or less.
change oil every 3K miles.
run the S2 oil filter
when you buy an engine--get one from a known reputable builder
limit your rpms to 8K
od
get the Mazmart oil pressure valve mod

There is some posts by MM (somewhere) about his experience running meth on his car?
In a nut shell -- basically by the time you add enough meth to prevent detonation you've displaced enough fuel to severely impact the horsepower.
While if you just add more fuel you will get the same safety against detonation while not impacting performance.....
I'm going to keep looking for those posts.
Sorry if I'm way out in left field here....

Geeeesh I'm sure to get a new one ripped for this, especially since I can't find the thread now .... but here I go

I thought it might have been in the Pettit Super Chargers Owner thread .....
(damn there is a lot of bitching and moaning in that thread)
Ok Brettus, I'll except that ... however I'm not a big fan of the what if game...but I'll play
What if you run out meth ... now you're in a lean condition again.
Not to pollute the OPs thread so I end just with this for thought.
Is it more likely to get a lean condition from:
- Running out of Meth
or a
- Boost spike
<shrug>
I dunno, I'm running nitrous right now ... but I'm seriously considering going with a turbo as a winter project (thus my interest)
I've got most of the supporting mods in place just have to commit to a turbo setup <rubs hands eagerly>

You can still run lean for various reasons even if your tune is rich - which was my point .
Also : most guys running meth do so for safety only and a failure in the system is not going to be catastrophic because the tune will support running without it .
So to get catastrophic failure whilst running meth you need two things to fail IE the meth system AND something else = highly unlikely .

Any thread where MM posts seems to generate such behaviour LOL

So tuned without the consideration of the meth.
The meth is added later as a safety .... ok
I feel bad for hijacking this thread ...
If you tune to run without meth ... then add it afterwards .. have you not in fact changed the conditions for which you tuned?
Does not the addition of the meth not displace the availability of air to burn ....
So now you are running richer than the intended tune, plus the added protection of the meth .... right?
