Compound boost

[GlassHammer]

Just came across this on Youtube, compound boost on a 5vz. Had to read up on it a little a found this tidbit of information.

The turbochargers are the more efficient power adder (supercharger vs. turbo). In the compound setups, the turbo boost level is limited because the air will be compressed again by the supercharger. If we use the turbos only to create 20psi, they are in a more efficient airflow range, but will lack the low-end power of the supercharger. With the compound setup, you can still have the instant boost and low-end grunt of a supercharger, but the addition of the turbochargers will allow for a much more efficient and powerful top-end. Interesting.

Buddy of mine who owns FAT tuning in Phoenix does a clutched supercharger with twin turbos on GT-Rs and such. Just incredible power bands

Nice. My buddy owns JackTransmissions.com. They do some ridiculous good work on Gtrs and Mitsubishi.

Cool to see s compound setup on a toyota 3.4l. They create some crazy power bands.

Awesome.

Jack's is known globally. Rich middle east kids ordering GTR trannies etc.

My brother did have some work done by them on his Evo MR; there was some arguments on a transfer case seal or something, but I guess Jack/crew did end up resolving the issue in the end.

Basically using a 3000$ supercharger as a buffer for the turbo, doesn't make much sense on an old Toyota truck. A 250MPH Texas mile racecar maybe.

Yeah man he has come a long way. Jack welded up his first exhaust on my brothers 90 talon on jack stands at his mom's house. Haha.

And yes the business of high performance trans work can be iffy. It's hard to keep this drivetrains in one piece and warranty becomes an issue. I know the guy and have had to fight for some warranty work in the past.
