What's up with that? Always see people with PDs doing that at the track.

The cold can cause case to shrink unevenly and not at same rate as rotors resulting in possible contact between rotor and case.

 

[Super Werty]

Yea it can cause contact between case and rotors. Big no no

Thanks guys. Good info

I'm going to rant here........

If you get an aftermarket tune/upgrade then buyer beware since it might not pass emissions (I'm talking about OBDII check only). Everyone will tell you passing emissions is all in the tune. I asked in a thread if anyone with "tuner stuff" passed emissions. Nobody responded. If you call the tuners, they will never make any guarantees and most cannot tell you it will pass or not. I failed emissions with just a tune an intake before. When contacting the tuner, they said that shouldn't have happened but couldn't do anything for me. Do a Google search and you will find others that had the same problem.

What I have come to understand is that the ECU has readiness monitors. These monitors need to be on and able to run diagnostic tests on the emissions stuff. The monitors do far more than just a simple check to see if the o2 sensors are on. When you get a tune, the testing procedures completed by the monitors no longer work correctly. This makes the car fail emissions testing for not being ready. Can't pass emissions, can't drive the car on the street.

Furthermore, some aftermarket tuners will tell you they don't mess with the emissions stuff, or that if you still have the cats you are all set. If they are touching the tune, they are effecting rediness monitors and therefore emissions stuff.

All the above has been a real disappointment to me since there is so much awesome tuner stuff out there.

Ok, I'm done now :-).

Dont run 87 octane through your supercharged engine.

Yeah, we have the same problem here in MA. What a pain in the cock! lol :frusty:
You can go the Roush route. It's 50 state legal and will pass emissions. I have a 2013 Roush Stage 3 and no problems for the past 2 years with state inspections.
Good luck!

Depends on your state but in MD with OBDII check a simple tune/intake/exhaust won't make you fail. I passed twice with my '11 with those mods installed. You do need your rear O2s on.

You would be surprised how many people do....

I bet 50% of the cars that come here for BETA testing, have to get the tank drained, because the owners run 87 in them.

Big mistake people make is boosting the PCV system by hooking it up wrong.

You don't. It shouldn't ever see boost on the pcv or the crankcase can't vent.

Simple. You follow the install instructions. To the letter.

If you don't really know what you're doing, you shouldn't be building your own kit.

Couldn't agree more. However I have seen it a lot over the years. Do not hook anything from the crankcase behind the blower.
