Should I Choose a Big Turbo or Twin Turbo for My Ecoboost Mustang?

I have a 2019 Ecoboost, and I’ve noticed that many cars with turbos have such loud spooling sounds that they seem to drown out the engine. I really love that sound. What do you all think is the best way to enhance both performance and sound from the turbos on a stock engine?

You should definitely check out the Ford Performance Bigger Turbo Kit. Just remember, don’t push more than 25 PSI in that engine or you risk blowing it up

Honestly, a four-cylinder engine doesn’t need two turbos. I’d recommend going with a single larger turbo instead. If sound is your main goal, do some research on the types of turbos out there. Some are louder than others, and they can get pretty pricey

That’s not entirely true. There are some situations where a twin-turbo setup can be useful for four cylinders.

I get that there might be some uses, but I haven’t personally seen them. In RayCharles’ case, a twin setup would be unnecessary and a lot more expensive than a single turbo option

I’ve actually had a different setup before. It was a compound turbo system, where a smaller turbo would spin the larger one, using the leftover exhaust gas to drive it. The bigger turbo acted like a smaller one but produced more airflow at higher RPMs, which gave a nice power curve

That’s interesting, but RayCharles was specifically asking about single versus twin turbos. Twin and compound setups are different beasts entirely. Still, I wouldn’t recommend it for him

Not really accurate there. Some twin-turbo setups for four cylinders use a smaller turbo paired with a larger one to reduce lag. It’s a pretty common approach

Actually, you’re mixing things up. The term “twin turbo” refers to two identical turbos. The compound setups you mentioned have two different-sized turbos, which isn’t the same as a twin setup

If sound is what you’re after, go for a bigger turbo and maybe switch to a different blow-off valve

Keep in mind that the stock block can only handle up to 25 lbs of boost before it might blow up

What does the factory turbo produce?

I think it’s around 20 PSI
