Do quick spool valves really work?
The quick spool valve works because you RESTRICT and speed up the air flow before it hits the exhaust wheel. Causing a faster spool. Yes you flow more air through one port but it’s the restriction that increases the air speed and adds kinetic energy which actually turns the exhaust wheel earlier.
What is a quick spool turbo?
The Quick Spool Valve is constructed entirely of high-grade 304 Stainless Steel and has a butterfly valve blocking a scroll of the divided turbo housing making the turbo act as if it were a smaller turbo. The valve sits between your turbo exhaust housing and the exhaust manifold.
What is a spool valve?
A spool is a cylindrical valve element that opens and closes ports when moved axially within the valve bore. Most spool valves use elastomers to seal between flow paths.
Do twin turbos spool faster?
Each turbo only needs the exhaust from 4 cylinders to spool it, so they are able to spool much faster than a single kit. Smaller turbos in a twin turbo kit can also make very similar power as a larger single turbo.
How do twin-scroll turbos work?
In contrast, a twin-scroll turbocharger gathers exhaust from pairs of cylinders in alternating sequence. The exhaust strikes the turbine blades, spinning them at up to 150,000 rpm. The alternating pulses of exhaust help eliminate turbo lag.
What is the rpm of a turbo spool?
The boost is achieved by using the exhaust flow from the engine to spin a turbine, which in turn spins an air pump. About 30 times faster than most car engines can go, the turbine in the turbocharger spins at speeds of up to 150,000rpm.
What spools up a turbo?
Turbochargers are powered by exhaust gases. One side of the turbo captures some of the exhaust gases (the rest get sent towards the exhaust system), which are used to spool a turbine. This exhaust turbine is connected to an intake turbine. As the intake turbine spins, it pulls air into the engine.
