Pro FWD

Pro FWD is a class in drag racing. The E.T. Bracket categories are no-electronics classes. Delay devices, throttle stops, air shifters, transbrakes, etc. or any device that transmits real-time, on-track data to the driver or any remotelocation are prohibited. All applicable NHRA rules apply based on elapsed time.

E.T. Bracket classes use a .5-second, full-countdown Tree.

Engine

Restricted to one, and only one, 4-cylinder, overhead cam, production-based automotive engine. Maximum displacement 2.8liter (170.75 cid). Engine swaps permitted; engine must be from same manufacturer as body. Redundant power adders, such as adual stage nitrous system or twin turbos, will be counted as one power adder. All engine-block and cylinder-head castings must be, or have been, available in a production car or truck from a recognized OEM assembly line with a minimum production run of 5,000 units. Transverse orientation may be converted to longitudinal orientation.

Exhaust

Hoses from bottle(s) to solenoid must be high-pressure steel-braided or NHRA-accepted hoses.

Forced Induction

All Applications: Restricted to a single turbocharger. All air entering the turbocharger must pass through the turbochargerinlet. Injection of any liquid, gas, or any other substance into the inlet or exhaust housing is prohibited. Turbocharger compressorwheel must be constructed of cast or billet aluminum. Exotic material wheels prohibited. Liquid intercoolers limited to waterand/or ice ONLY.

Four-cylinder, single-turbo application: limited to maximum 88mm turbo, where the maximum compressor housing inducer diameteris 89.5mm (3.523 inches), measured at the point where the leading edge of the compressor wheel meets the housing. Compressorwheel inducer diameter not to exceed this value, and contours of wheel must not be “stepped, notched, or clipped”; i.e., the contoursmust be continuous features from the inducer to the wheel exducer. All air entering the turbocharger must pass through theturbocharger inlet.
