2019 BUYER’S GUIDE team, these pistons are ready to handle serious abuse and drastically decrease the lead time from custom parts. required to tune RPM steps in ECUs, and allow turbochargers to spool up to realistic boost levels. They also offer a great horsepower-per-dollar value, compared to expensive A/C motoring ab- sorbers.

AXLE-HUB DYNAMOMETER DYNOMITE DYNAMOMETER HEX HEAD SELF-EJECTING QUICK RELEASE FASTENERS 603-226-3966 www.dynomitedynamometer.com DRAG RACE SOLUTIONS More than flash-acceleration horsepower is available from DYNOmite load- cell equipped eddy-current absorption systems. They permit indefinitely* running steady-state, RPM-step, or sweep-HP tests – under computer control. Absorber loading is vital for ECU driv- ability mapping or emissions work. In compar- ison, inertia-only “dynos” can’t hold an RPM point, but calculate power from flywheel (roll) mass acceleration – like deriving HP from drag strip mph. Eddy-current absorbers are well suit- ed for axle-hub dynamometer tuner/testing ap- plications. They provide the steady-state loading 615-587-2027 D r a g R a c e S o l u t i o n s ’ H e x- H e a d Self-Ejecting Quarter-Turn Quick-Release Fas- teners come in sizes of both #5 5/16” or #6 7/16” large head Pro Stock-style designs.
