Amen to that.

 

Ummm,............yeah and no. The stock engine can take the supercharger as long as you aren't full out racing every single day and beating the crap out of the car every single day.
If that was the case, then the Magnuson that Burton put on his car would be a lot more dangerous to his car than said Roushchargers on stock 5.0 Mustangs. (His tune is said to be 600 crank HP as opposed to Roush RS3 cars with 565/ 575 horsepower from factory.)

 

That is correct tony. Talked to magnuson extensively, along with several known tuners. 5.0 stock can handle about 600whp safely. So 530ish whp is plenty for me with magnusons box tune. I'm well within "safe" zone. And no I don't race or track or abuse, so I'm confident in magnuson and their engineers. That's why they offer 5 yr powertrain warranties.

 

Yes sir. Any more than 650 crank HP, I would go forged internals. That's just me though.

 

Has anyone else upgraded to Phase 2 on their stock 5.0?

Any problems with the extra 50 HP?

 

Indeed, why expose yourself to 2 extra years of liability if you don't have to. An extended warranty is a almost purely a money maker. You don't mind paying for the peace of mind (Roush probably more than any other outfit knows how far you can take the engine without seriously compromising reliability) and Roush gets to put the money in the bank and collect the interest.

If the extended warranty was anywhere near a break even proposition or worse you wouldn't see an extended warranty for their product unless it was absolutely necessary to move the product.

Hell Whipple will provide a 8,000 dollar powertrain warranty (5k engine, 1.5k trans, 1.5k diff) that matches the new vehicle warranty (5yr/60k for Ford) when purchasing a new kit for a new car albeit probably only 525hp at the crank or maybe more as they don't spell out which kit might have a warranty exclusion.

 

If you got to Phase 2, which I was going to do when I had bought the car, your car will not pass emissions, unless you have the stock tune on your tuner to revert to.
(I was going to do the Phase 2, had everything filled out for it, but upon further investigation about MA emissions and not passing, I opted out, just to be safe. Even though I would have the original tune on the SCT tuner, just being safe. Who knows what the future holds though?? )

 

That's strange, here in Texas it would pass even at phase 3 so long as all emission equipment was in place and functioning since all they do is a OBDII hookup to check that all emissions are functioning and a visual to make sure all the equipment is in place. I bet tennessee where that other car is will be the same way.

Massachusetts must have emissions laws like california.

 

Same here in Georgia, add long as your equipment is in place and no check engine light you pass

 

Winner, winner, chicken dinner.
Unfortunately we do. Otherwise, I would have gotten the Phase 2. I need to move.

 

What is it that would cause it to fail, the CAI? OBDII wise it should be fine. My phase II is due for Texas inspection this upcoming February but I don't think I'll have any issues.

 

So tony, I think I'm confusing myself... So you have a stage 3 roush, but that's the phase 1 (575crank hp) kit... Is that correct? So the phase 1 kit will pass emissions? Luckily in Iowa there are no emission laws. Curious tho, would my new setup pass emissions if there was one?

 

Same here...no emissions testing in East Tennessee, so no worries.

 

I keep seeing "we have no emission laws in our state" but of course this is not the case. Individual states may not do testing, or only do minimal testing, but they all have emissions regulations at the state level, and of course at the federal level.

Anyway, unless your state is like CA, or MA, or one of the other states that does stringent emissions testing, you should be able to pass inspection with any of the Roush phases so long as it is on the Roush tuning or the aftermarket tuning has not disabled any of the emissions equipment and all are in place so it would pass a visual inspection.

Now, if you live in a state, or a county like some in Texas, that only does a safety inspection then you are gold, do anything you want and still pass inspection.

 

I am thinking it might be the cai that may throw it off. All I know is that it would not pass MA emissions, so I opted out like a fool. I should have gotten it and just throw the stock tune come emissions time. I may still update someday.

Mine is the 2013 car, so I have 565 horsepower.
If your kit says that it is 50 state legal, you will pass emissions in all states, including MA and CA, which have stricter emissions testing.

 

^ I need to check with Maggie folks to see if it indeed is.

 

I am more than certain that the kit is 50 state emissions legal.
