First, best wishes to Greg Hardee on his birthday, and thanks to his circle of friends that treated us to a day at the Pahrump, NV racetrack.
The BaschBoost Supercharger (BBSC) is a winner. My thanks to Chris of Science of Speed for a half dozen laps in his vehicle. Chris' NSX pulls 1.01 G and he was able to use all of it in spirited (understatement) laps around the track.
His BBSC equipped NSX pulls like Godzilla. The vehicle accelerates at such a rate it snaps your helmet into the headrest. The G forces around the curves require a seat with better bolsters than stock -- he uses Recaro's. Also, a four point harness is a good idea and you'll need a smaller steering wheel.
We ran the course basically in third gear -- even through the chicanes and tight S's -- until the straights, when fourth was used. Speed was near 110 mph two-thirds along the major straight. After hard braking with a setup at the apex, smash the pedal and your neck snaps back again.
This was unquestionably, in my 30 years of foreign sports car ownership and an NSX owner of 11 years, the most impressive aftermarket power accessory, NOS not included, I have seen for the money. I am not a fan of turbos, so this prejudice must be taken into account in evaluating this statement.
The engineering looks sound, in the opinion of this PE (electrical). Unlike the CT Supercharger, the BBSC does not require any change to the alternator location. Induction plumbing can either use the stock intake or K&N. The workmanship and quality of parts, including fasteners, appeared top notch.
After studying the installation, my sole empirical concern was the BBSC drive belt. It wraps around a new pulley in an "S" arrangement so as to spin both the SC and the alternator. However, after countless shifts at redline, my fears were calmed.
As a comparison, I ran a number of laps in my stock NSX (94), and the best I could manage was 20 seconds off Chris' pace -- and I was "drifting" around the tight corners. This revealed to me that to take full advantage of the BBSC power, changes to suspension and tires are likely in order.
I noticed no "hiccups" that might indicate a fuel management or delivery problem. No detonation was heard, although it was a "cool" day, about 70-75. The temp gauge indicated standard, engine operating temperature throughout the run. I will be looking forward to see what happens to emissions with the BBSC.
All in all, it was a unique experience. Thanks to Mark Basch, Mark Johnson, Dave, Heidi, Andre, and others for a fun day.
