what is puts more stress on the engine: Turbo or SC

[Gavros 4 Life]

lets say twin turbo or ECS SC plus which of the two require less maintenance?

much appreciated!

I would say both do but if I had to choose... turbo puts more stress. Waiting for other people to chime in.

You got a much loaded question there, sir.

For the same HP output, the turbos will be less because they're driven by exhaust. The centri is belt driven and uses 35-50HP to drive it, therefore robbing you of some output, so it takes more HP to "use" a centri than turbos, to make the same RWHP output.

As far as I know, turbos are plug-and-play. They're generally oiled by the engine oil. A centri usually has a closed-loop oiling system and requires changing periodically. Also, the belt may need to be changed from time to time.

Which is better? You get to decide that because both FI you're asking about are supreme! Just depends on what your goals are and how you want to get there. Good luck deciding.

Blower needs to make more crank HP to put the same to the wheels since the blower takes HP to spin. It also puts more load on the crank/bearings and any other accessories run off the blower belt. A self contained blower needs added oil changes.

Turbos tend to make more torque which could but if the torque was equal then the centri would be a bit more stress. The excess torque can be tamed down with proper turbo/ar selection or a boost controller.

With a quality kit neither one should have issues.

Its a toss up to be honest.... depends on power level

Both can be a royal pain or both can be years of trouble free fun and power. Pick your setup, tuner, and shop wisely.

In terms of maintenance, it's simple. Yes, the ECS base kit does require you to change the S/C oil the same time you change your engine oil, about 5,000 miles. It's generally not a big deal because it's right there and not difficult to do. However, ECS can provide the S/C in a non self-contained unit, which means that it will rely on the engine oil to lubricate the gears and bearings inside the S/C unit. The downside to that is, it costs slightly more for that setup. Only because the oil pan needs to be tapped so that the oil can drain out of the S/C and, with that said, the oil feed and return lines needs to be routed. IMO, that setup is more efficient because the temperature will warm up as quickly as the rest of the engine. It is also arguable that the synthetic fluid that is provided with the blower, breaks down quicker than the engine oil. Either one is good, but if you decide to upgrade to a YSi, the oil lines will need to be run regardless. Turbos can be temperamental. They are a great product, but when or if it fails, they're mounted underneath which means there is more work involved in removing and reinstalling. Again, some oil fed units which will still require oil lines to be run. Obviously, I'm more knowledgeable about the S/C because I have one, but either setup you get will be great. Both are equally powerful, and even though it takes power to make power with the S/C, they can give just as much of a punch as a turbo.

If HP is the same at the crank your cylinder pressures will be similar for both. However, there is more load on the crank snout with a Centrifugal style blower. Over time, the centrifugal will be easier on a motor purely because of the way the torque curve is shaped. It's a real toss up, but keeping fresh fluids in and not beating on it 24/7 will make a huge difference.

Turbo does.
Makes its boost fast and down low. 8 psi at 3000rpms more stress then centri that makes less boost down low.
Also turbo makes more under hood heat. More intake air temps got make sure good intercooler setup.

Now if looking for big power and better gas mileage turbo the way to go. These engines pretty stout so should be fine either

It would be hard to say between a top mount compared to a turbo but the front mounts are the easiest on the engine.

sc, takes more to spin it as far as crank goes, but both are a bit too much for my liking on a stock block if its a dd. i have a 200lb foot that loves to hear the toy i put on the car.

Wait what.. u r saying supercharger too much for stock block?

If cylinder pressure is the same then stress is the same besides maybe the added stress from the belt on the crank with a blower.

Extra low end of a turbo makes more power, same as a PD blower so you could say it is more "stress". Power=stress, more power more stress.

If turbos are placed down out of the way the heat isn't really an issues. good kits like the AGP or IPS kit have the turbos right where the cats were which cats get extremely hot so that isn't really an issue. If you don't want extra low end power (something people rarely say or do) then use a electronic boost controller to ramp boost up later in the RPM curve and also use it to turn boost down in daily situations. You can have 500-750rwhp on tap easily with a stock motor just going from 5 to 12psi using a boost controller.

Stock blocks have made 1100+ with decent pistons/rods. Stock motors with a good tune/fuel/etc can live a nice life at 750-800rwhp.
