Turbocharging Superchargers

[Eighthtry]

OK, guys. I keep reading about nickel and diming our way to more horsepower. Maybe a supercharger here or there. A whopper of a K&N filter/housing. A big argument of what oil and weight to run. What additives to use. Does one use a catch can or not.

So screw the little stuff and let's escalate the arguments to the professional/theoretical level.

Who has turbocharged a supercharger before? Turbos are incredibly complementary additions. There is some dead serious horsepower available. One can add some whopping turbos because the lag problem goes away. I suspect there would need to be some serious block building (V6 or V8), frame stiffening, brake upgrades, and more needed to support this "hold my beer and watch this" project. Then we could start some new arguments on cooling, filters, oils, additives, catch cans, headers, mufflers, exhaust pipe/muffler size, rear end gearing, wheels, tires, transmission.....the mind spins. Gosh, the list is undefinable at this point.

I can't imagine the programming problems. Foreskin will be overwhelmed. Or screw it, programming problems will surface before, during, and after on this one.

Then, when it is taken to show it will automatically get a best in class trophy even without all the body mods. Which probably births a new show class just in the F150 classes.

I have challenged but quickly exhausted my knowledge. We have some participants on this forum that have plenty of knowledge to start and contribute to this conversation.

This is serious, doable project. Who is in?

It’s called twin charging, I think Volvo and VW did it in production cars once upon a time.

Definitely possible, I would love to see it happen in a F150, just uhhh, make sure to upgrade the 10r80 also, cuz it might leave the chat with a bang if not ready.

Wasn't there super duties that had a large turbo along with a small turbo? The small turbo would boost faster (obviously) to minimize some turbo lag.

A smart computer told me

”Several manufacturers have employed both a supercharger and a turbocharger on the same engine, a setup known as twin-charging. This combines the instant response of a supercharger with the efficiency of a turbocharger. Here are the notable examples:

Volkswagen
The 1.4L TSI TwinCharger engine, used in models like the Golf Mk5 GTI, Polo GTI, and Scirocco, paired a roots-type supercharger with a turbocharger. The supercharger provided low-end torque, while the turbo took over at higher RPMs. Production ran from around 2006 to 2014.

Volvo
The 2.0L T6 Drive-E engine, found in models like the XC90, S90, and V90 (2014–2018), used a twin-charged setup. A supercharger delivered power at low RPMs, and a turbocharger kicked in for higher revs, improving efficiency and performance.

Lancia
The 1980s Delta S4 rally car featured a 1.8L engine with both a supercharger (Volumex) and a turbocharger. The supercharger provided immediate throttle response, critical for rally racing, while the turbo added top-end power.

Nissan
The March Super Turbo (1988–1990) used a 0.9L MA09ERT engine with a supercharger and turbocharger. This rare setup was designed for the Japanese kei car market, delivering surprising power for its size.

Toyota (conceptual/historical)
While not mass-produced, Toyota experimented with twin-charging in the 1980s MR2 prototype and later introduced the 2.0L 3SGTE engine in rally cars like the Celica GT-Four. Some aftermarket or racing applications of Toyota engines also used twin-charging.”

There "MIGHT" OR "COULD BE" someone that has figured out how to build a superduty 10 speed. Remember, this is borderline fantasy. Ford is bound to have a good automatic in their large diesel trucks. Or maybe an Allison?

With the supercharger providing instant power while it is sucking the turbo, then turbo lag becomes something of a question like "how big a turbo can I put on it before I can feel the lag?"

Any thoughts on that assumption? How much hp can we pull from this? What does this do to our torque curve? I'm thinking torque will be 10 or 15% below hp.

A "smart computer" would still be waiting on me to copy and paste. This is quick regardless of where you found it.

08-10 super duties (6.4 power stoke) were a compound setup... Smaller turbo feeding a larger turbo... With a good tune it was capable of close to 600whp with no other mods... My brother had one and would peg out the 40psi boost gauge

 

[Davidwnuc]

I have only read about it. Search for compound boost mustang and you will find a bunch of info.

 

[Acagro]

Midnight performance has twincharged a 21+ F-150 already you could message him for info on the setup.

Shame the pistons cracked even at stock pressure lol

Why rely on hardware like superchargers and turbos. The new thing coming back around again is bottle fed psi charging. No hardware like turbos or superchargers. Just a big bottle of compressed air. No lag. High boost levels. Read up on that before jumping on that turbo to super combo.

I recall this patent from back in 23

Ford Creates Radical New Twin-Turbo Design

Midnight has done a Blower/turbo combo but itll depend what your goals are thats a lot of moving parts. People are making great horsepower with Whipples, Twin Turbos and Centris. So in the end what are you after with doing a blower/turbo together?

An air compressor is a novel idea. I have one to run the air shocks on my 2023 GMC Yukon Denali XL. It has some spare time available. Probably need to upsize it though.

Good question. Car and truck shows come to mind. No one else will have that plumbing there. Always an expensive way to get a trophy.
