The Precision Turbo Next Gen R 73.9 is a race-proven evolution of the original 73.9mm turbo that currently holds the xFWD world record at 7.69 @ 188mph. Now updated with a new compressor wheel and redesigned compressor cover, the R version delivers over 10% more horsepower than its predecessor — and it’s fully legal for xFWD and Super Street competition. This turbo is engineered specifically for the extreme demands of front-wheel-drive drag racing, including top-tier Honda K-series builds. A built-in speed sensor port (sensor sold separately) offers critical data for precise tuning and launch control strategies. It’s already made history: the 73.9 R powered the world’s fastest K-series xFWD car to a 7.82 @ 192mph at ATCO Dragway. Whether you’re chasing records or aiming to dominate the lanes, this turbo is built to perform.
