KraftWerks Powers the World’s Fastest Acura Los Angeles-based Hondata co-owner Doug Macmillan set 3 new land speed records at Bonneville Speed Week 2008 on the Bonneville Salt Flats this past week.
Doug Macmillan started the week by setting a new record in the G/BGCC class of 221.652 mph in his 2L K20A Acura RSX running twin Rotrex Superchargers, installed by Norco, CA based KraftWerks. This record gave him his goal of acceptance into the vaunted Bonneville 200 mph club. He went on to also take the G/BGALT record at 208.646 mph.

The crowning glory of the week however was the G/BFCC record, originally set at an impressive 226 mph in 1990. Doug has previously thought this record was out of contention, until he saw the performance of the K20A engine in combination with the twin Rotrex Superchargers fitted by Supercharger experts KraftWerks. At the 4000 ft altitude of the salt flats, the supercharged K20A was good for around 600HP. On the qualifying run, Doug scraped in with a 227 mph pass, going into a spin after the fifth and final mile, flat spotting all 4 tires. On inspection, 2 of the tires were throw-aways and two passed marginally. The team only had 2 spares which Doug could use, so the decision was made to swap the 25” tires from the rear to the front and put the spare 26” tires on the back. This decision was fraught with anxiety, as it changed the gearing of the car and would require more horsepower to get the RSX up to a record speed. During the first pass, Doug didn’t make use of the nitrous bottles in the back – at this point used for ballast only. Now the team needed the extra horsepower that the nitrous could give, only Doug had never tuned this engine with both blown and fuel combinations. It was a case of “give it your best guess”, and who better than tuning guru, Doug Macmillan! The RSX pulled an impressive 234 mph with the additional 100 HP nitrous shot and stopped straight this time, with no drama. That this speed was achieved in a production chassis, with off the shelf Honda gearbox parts and camshafts is a testament to the strength, quality and engineering of Honda products. The new record is now set at 230.653 mph.

Hondata’s RSX, with KraftWerks superchargers, is now officially the world’s fastest Acura!
