Okay thanks guys as you can see there is always another way to skin the cat, never thought of hydraulic. Ia,
What about the load rating, not sure on Modern Blowers but the old 6/71's would take 100hp to turn at 5000 rpm.redrocco;1891165 said:The VOLVO/PARKER F11-005 hydraulic motors are rated for maximum intermittent of 14,000RPM and max continuous of 12,800RPM. They are used on hydraulic chain saws and other such high speed apps. They only weigh about 11 LBS and are about 4 inch by 4 inch by 5 inch. The eaton M112 supercharger has a max RPM of around 14,000 and the M90 is around the same. Most whipples max out at around 16,000 so if any of these were driven by the F11-005 they should make plenty of boost.

Poodles;1892431 said:Yep, lots of ways to do it.
- Quick-spool valve
- Antilag
- Honda's flapper style
- Porsche's moving veins
- diesels that slide a plate back and forth
Even without that, a modern designed turbo (turbine wheel, compressor wheel, housings, ball bearings, sized correctly) will spool like nobody's business and supply serious low end torque.
Hell, a properly sized turbo doesn't really have lag. If you have lag, it's called a transmission...downshift.
