Race fuel selection is about more than the octane number. Learn how AKI, RON, MON, oxygen content, ethanol, lead, stoichiometric ratio, fuel-system capacity and calibration work together.

A 415-LPH DW400 fuel pump is not a universal horsepower guarantee. We break down C6 Corvette fuel pressure, pump voltage, E85 demand, injector headroom and how to validate the complete fuel system under load.

C5/C6 Corvette cranks slowly or will not restart hot? Learn how voltage drop, aging cables and grounds create heat-soak starting problems and how the SMG Hot Start Kit addresses the high-current circuit.

A camshaft swap changes more than lift and duration. Learn why LS/LT pushrod length, hydraulic-lifter preload and rocker geometry must be measured with the actual parts before startup.

Horsepower claims can be useful, but only when the test method, baseline, fuel, calibration, temperature and supporting parts are disclosed. Learn how to separate a meaningful before-and-after test from a headline number, and how to choose upgrades that work together on your vehicle.

A finer oil filter is not automatically safer. Learn how full-flow and bypass filtration differ, what micron and beta ratings mean, and why pressure drop, temperature and contamination determine the right setup.

Lambda keeps fueling targets consistent across gasoline, ethanol and changing E85 blends, but only when the wideband sensor, ethanol-content data and logger scaling are trustworthy.

A larger heat exchanger is not always the first answer. This diagnostic guide shows how to test supercharger intercooler-pump operation, air pockets, IAT2 rise, cooldown recovery and the actual limit in a liquid-to-air cooling circuit.

Stainless braided brake lines can sharpen pedal feel and improve consistency, but they do not create tire grip or cure boiling fluid and pad fade. Here is how to upgrade the whole system in the right order.
