I personally know of 3 blown engines...

Well you are making my point about whats "safe". As far as blown engines i hope at some point we can all discuss the details of those builds

I agree, This will definitely help others determine what limits they want to go and what parts they can start looking to replace.

Don't get me wrong, it's their money and their choice and they can do whatever they want to make themselves happy, but hiding the reality to push the others to go their way (and of course make somebody else more rich) is not fair and ethical... well...IMO

I agree - the tuners need to be more open about it. If/when I blow my engine I will be open about it :-)

The issue is you can't attribute abusive usage (poor gas, tuning, other idiotic things people do) to longevity of these engines and components. So far in my opinion a well tuned and more importantly consistently maintained car can run 720-750whp day in and day out.

wont happen. i wouldn't be posting up here if i blew my motor running 800+ hp and having it towed to the dealer for "goodwill" and the tuners sure as hell aren't going to speak up.

O2 sensors fouled due to catless DPs?

No, just changing them every 10k miles

10k mile routine for my car

02 sensors
Spark plugs
Coil packs



3k oil change a must!

Imagine 900hp car all that stress circulation inside engine that density of oil would be like water if u dnt do it at 3k.


Sometimes 2k. Whats $150 spending than a whole engine. Lol

understandable

Please excuse my ignorance, how does your tune impact the life of your coil packs? Plugs I understand, but coils should last every 2-3 plug changes right?

[allmotor_2000]

I change oil every 2K as well. Plugs at 10K... coils not that often.

hey bud,

allmotor is right not often you change coils,


but i just don't want to take any chances
so i replace them same time with plugs,
so we eliminate any possible errors

Gotcha. I guess it's not terrible if you do it yourself. OEM parts are $630/set.

Replacing ignition coils when doing plug changes?! Isn't that a bit excessive?

Always good to have fresh coils

[m5james]

Seems like misfire codes would be the giveaway before dropping $600 +/- every 10-15k.

[BPMSport]

I always suggest coil replacement on 2013's and below when tuning the car. Have seen too many of them go bad, even one that exploded and shorted the dme.

Worth the $3-400 price tag to prevent a more expensive one...

[m5james]

1st gen X5M vs M5, so nothing like the power you guys are pushing, but I guess I should replace them since I'm pushing 70k with a handful of mods.

[NightM]

The coils are still good at 10k no misfires just taking Precaution jst in case any happens we eliminate all these wear n tear on parts.
Prevent all this misfires and any other stuffs

Coils and plugs are cheap- a missfire can bend a rod or melt a piston land- not so cheap.

If running lots of Meth, 3-5k on oil sounds right- could send oil for testing but it isn't worth it in my opinion, just run fresh oil and filter.

Where do you go for plugs and coils for ~$300?
