Are there any compound turbo users on here?
 

Ive been reading information on them and I think it would be kind of cool to build a beta to handle a compound turbo. Theres probably more work that would go into it and the tuning would be way different but I think it would be unique and different to have one. Thoughts?

its your pocket book, unique it up, but for us other 99.9% of the automotive community, turboing a hyundai is unique enough

If you're going to that much trouble, it would be better on a small displacement motor to twin charge with a small turbo feeding a supercharger. The problem with compounding a bets is that you'll be siphoning extra exhaust gasses, where leaching crank power would prove much faster spool-wise, as the gasses are dedicated to one purpose, and have the same effect as the compound system.



The concept is simple enough, compressor => into => compressor multiplies = boost multiplied by boost.

Tuning a compound turbo system would be the stuff of nightmares

Sizing the turbos would be bloody hard

That's gonna be one complex and heavy exhaust manifold



Food for thought. What would be cheaper?

-Use nitrous to spool up a large turbo. Chew through two 10lb bottles a month, at $40 per refill. Setup cost: Maybe like $600 bucks for a dry nitrous kit? You're already running aftermarket management and tuning the car. Cost over one year: $960 of nitrous, and you have a running motor



-Use a smaller turbo to spool up a large turbo. Save money on nitrous. In six months time, on a super hot summer's day that you couldn't replicate in the dyno room in winter, strange thermodynamic sh*t goes down between turbos 1 and 2, destroying both turbos and your engine.



Ehhh. It's pretty common for RX7 and Supra owners to bin the sequential turbo system.
