Okay so I have an 06GT with 5000 miles on it and decided to add the Roush Supercharger. Being worried about warranty etc, I had it dealer installed. Now the fun part, everything seams to work fine except on cold start-up. When cold I get a real good cloud of smoke coming from both exhaust pipes. Only lasts a few seconds but is very noticable. I am also told under hard excelleration I get a short puff of smoke as well. Now I don't think this is right and take it back. The dealer calls Roush engineers and are told this is normal. Now I don't buy it. I figure I am loading up on fuel and washing the cylinders. - Can't be good. Anyone else have a Roush Supercharger or can I get feedback from people with regards to the smoke. Am I worried about nothing?? Can this really be normal??
No way smoke is normal........mine does not smoke on startup or acceleration. Mine was dealer installed as well. Is yours running OK? Maybe you could have it dyno'd to support your argument. You may want to search the fnsweet.com forum for similar problems. I have read some simple fixes such as improper spark plug torque for s/c problems.
This is the kind of crap I hate to hear. You paid too much to be treated like that by the dealer. How many of these have they installed? My dealership had installed several, or I would not have done it. If they have done others, they would know this is not right.
Under certain circumstances, these new mustangs will smoke some when you start them. For example, if you start the car when cold and move it across your driveway, then get in it the next morning, you will likely get some smoke.
This should not be happening regularly though and not under acceleration.
Is the smoke blue or black?
If it's black, it's rich, and they may not have gotten the ecu reprogrammed properly.
If it's blue, it's oil, and not good.
Either way, as others have said, it's not normal and you should not accept a brush-off.
Don't worry!They'll fix it if you have a problem down the road.The set up is reliable.Any car driven at WOT will puff.It's barely broken in.Check your dipstick and if you are eating oil,mention that to your dealer.Always give your car time to reach normal operating temps before booting it.

I have the Roush as well and have never noticed any smoke. Except from the tires
Mine does however, have a slight hesitation after start up. It's as though it cuts out for a split second at around 2000-2500 rpm under light acceleration. It goes away after driving for a few minutes. I'm going back to the dealer again today to see if they can replicate it.
I get a "cut out" initially with mine too first thing in the morning but it is only for the one time.I am sure if I let the car sit and fully warm up , it would cure it.I have a 5 speed manual.I have a S3 friend with an automatic and his doesn't display the problem.Mine isn't going back for that yet,because I assume it is in the tune.I can't be bothered waiting for them to send the computer to Roush to be refashed.There is no guarantee it won't come back the same.
Sounds like you might be suffering from what many of us force-induced GT owners are dealing with.............blow by. Aeriated oil is being sucked into the intake through the PCV system and it can settle on your plugs when you stop the car. I noticed this when I pulled my stock plugs a while back to install my HTO's. If the car sits for a while, this oil can collect around the plugs, and the car will idle rough or even stumble on startup for a few seconds before returning to normal. It can also cause smoke to spring from the exhaust briefly on startup as well.
All GT's are suffering from this problem, but its much worse for those of us who use nitrous or have turbos or superchargers because we ingest more feedback oil fumes through the intake than NA cars do. And depending on how you drive your car, the tune, mods and such......it may or may not be a problem for you. If it's a big issue, then you may want to start looking into installing an air/oil separator or catch can onto the drivers side of the intake. The passenger side shouldn't need one.
I would post a couple of links to "another" website that has a very good thread relating to this very problem......but this site will block it if I try. So I'll just offer up some pics of the air/oil separator setups some of those guys are using.
The first one is on a Saleen s/c'd GT (he installed this one on the passenger side, but you only need one on the driver's side).

The second pic is on an NA mustang with the stock intake manifold. Just make sure you use better hoses than he did

The last two pics are of a setup on a KB supercharged GT. I've circled the catch cans so you can see them better.
Unfortunately, while it sucks to have to deal with this problem.........it isn't a new one. This kind of issue has existed for years.......not just on the new mustangs. As I said before, on an NA GT not pushing alot of HP over stock, it is a minor issue. But if you are running nitrous regularly, or you have gone with a forced induction setup......you should look into a solution to control or rectify the problem. Aeriated oil ingested back into the system thru the intake can potentially clog up your intercoolers, ruin your mpg, and in some cases lower your effective octane usage.
Of course, I don't want to alarm anyone....as the severity of this problem has not been established. It may not even be a big enough problem to warrant any action against it. I am by no means an expert on the subject, I'm just relaying the input I have been given. As I learn more I'll be happy to post back. Or if someone in here has better knowledge on this subject, I invite them to chime in.
It would be interesting to see how much gets filtered out.
Those seperators look like the ones meant for compressed air lines.
Thanks for posting this!
Actually, they are just that. Steeda sells the ones above made for 03/04 Cobras, but they will work on any vehicle. And yes, you can even use a separator for ordinary air lines..........you'll find everything you need in a local hardware store. Then there some really nice, purpose built catch cans made by companies like HKS and such....and these may cost you more (depending on where you get them), but they do make very nice, clean underhood installs.
As far as how well these work, well it depends on how well the separator you build/purchase filters out the oil. Any separator will be better than none, of course. And as I said before, on an NA stock or bolt-on GT it probably won't be as much of an issue. The small amount of oil you'll see getting reingested would just be burned off by the motor. But I've seen a guy with a KB s/c fill up an entire Steeda air/oil separator reservoir just on one night's worth of runs at his local track. That's how much oil is being circulated into the intake on cars with power adders. It won't kill your engine, but it can make it less efficient over the long term.

Yeah mine started by just "cutting out" first thing in the morning. Now it does it nearly everytime after start up, whether hot or cold. It will last for about 5 minutes or so cutting out at around 2000 RPM. After that it's fine. The dealer was able to duplicate it. They're pretty sure it's something in the tune. They are waiting on Roush for some feedback on the problem. Hopefully I know something early next week.
WOW!! Thank You everyone for the great feedback have a lot to look for and a whole lot less to worry about. Still trying to get the car back into the dealer. developed a cooler leak from the Roush resevoir, been waiting a month for the replacement to come in. Dealer says Roush is the problem, finding that hard to believe at this point.
As for the smoking here is what I now know:
Smoke is more white then black.
Car does not smoke (much) on startup when driven daily.
I am using a little oil (maybe a few oz's in 2,000kms)
The longer the car sits - the bigger the smoke show.
The idea of putting in seperators sounds great to me and thats next on my list. It has been suggested to me that I might have a bad injector or two. I am told that an injector can leak while sitting, the longer it sits the more excess fuel sits in the cylinder, the larger the smoke show on startup. Any ideas on this? Does it make sense and can it be diagnosed??
GREAT NEWS, The Dealer finally agreed to get serious about this and found a leaking intake gasket. Can't wait to get the car back. They have only had it for 7 weeks.

Is it true most cars that up grade to a Super charger or a Turbo that the Check Engine light always becomes an issue being on????
