2015 V6 vs Ecoboost

[bluebeastsrt]

I was wondering about how Seafoam or Scheaffers would work. I've seen some spotless 200-300k+ mileage engine teardowns with those additives, no sludge at all.

Ive read that those products aren't any good because they actually exit with the exhaust. And interns plays havoc on the turbocharger.

Good point!

I've also heard seafoam and the like are not good for turbo chargers at all.

the carbon build up is from oil in the pcv system, A good catch can will do wonders, and water meth injection is also very good for cleaning and performance. The cleanest intake tract i have ever seen was on a water/meth car, valves looked new.
Seafoam will kill your turbo seals, stay away!

Isn't that the point of the oil catch can?

It appears chemical cleaning is the best option right now. Not exactly a selling point. Meth injection might help. Place a nozzle on the cool side of the inter cooler.

You will get pooling that far from the intake. best place for a single nozzel is behind the throttle body

While the technology itself has been around for 10 years, I have yet to see a 10 or even an 8 year old DI engine...

Maybe they're all still in the cars, which is a good thing. Here is an example. I'm sure there are many more out there.

Not under boost it won't. Have the spray come on at a set boost pressure. I had a SRT-4 with number 6 nozzle on the hot side and a number 8 nozzle on the cold side. Car ran like a champ. First nozzle would come in at 10psi and the second at 16. This set up was the only way I could keep my race tune from kicking out when the car sensed knock. Full boost was 25psi. But a single nozzle closer would probably have the same effect different means to the same end..

the problem is droplets falling out of the air stream on sharp turns, which it looks like to me on the cold side of the inter cooler of the ecoboost there are two near 90's.

Water meth pooling will really only cause uneven distribution of the mix to the cylinders which is not as big a problem as uneven fuel distribution but can still give you some erratic afr readings.

I know nozzles on the hot side work wonders for keeping the inter cooler from heat soaking. Did you ever get a chance to pull the intercooler after a run and see how much water fell out?, the only cars I ever saw with hot side injection were pure track cars, and one guy went as far as having a drain plug put in on his IC. it was never very much mind you, a couple of cc's max after a long lapping session but I'd be worried about internal corrosion on a street car.

No never pulled the intercooler. But there wasn't any harsh bends between the nozzle and the intake on the old car. Maybe 45 degrees at worst. But once the car was totaled I parted it out and did not see any signs of corrosion on the intake runners. The head was spotless, like new condition.

Intake runners will never corrode as there is no way water or meth can stay in them long enough to corrode anything. Also with 45 degree bends you wouldn't have much chance of droplets falling out anyways.

With meth injection before the intercooler, the water and meth enter the hot and dry air and instantly vaporize cooling it, which is awesome, but that air is problably now at 70 to 80% humidity for it's temperature and pressure. the problems you have are the pressure and temperature drop which is so sudden that it can bring the charge air down to it's dew point and literally make it rain in the inter cooler. We all know that meth and aluminum don't play nice together, but the amounts are so small that it usually will not make a difference, unless some sits at the bottom of the inter cooler for a while.

The performance benefit, as you noticed in your SRT far outweighs the drawback, and you probably drove home with the meth turned off so would have dried the inter-cooler anyway.

With the Ecoboost cold side making the two tight bends and running near vertical, i'm sure it would have more water loss than your srt and the intercooler looks like a PITA to get to.
