STAGE I, II and III TURBO KIT

10.48 @ 139.32 mph 1/4 mile

"I went to the drags again this weekend with my NSX and ran in a NO BULL series in the 10 second class. It was incredible. I didn't plan on making it past the first round. There were six cars and none of the others were actually street cars. In the first round, I had to race a guy that has been the points leader of our local track the last few years. He was driving a nitrous Vega drag car. That run was my best ever. I ran 10.73 @ 133.78mph vs. his 10.94 @ 124.63.  It was incredible. Then I went to find out who I raced next and I found out that two of the cars got disqualified for breaking into the 9's. I ended up racing a nitrous mustang in the finals. He beat me when he ran a 10.40et. I ended up second in a class that I probably didn't have any business being in.  Jimmy from HP was at the track again doing my tuning and making sure that the car was running safe. He changed my boost settings this time compared to last time i raced. This time we were starting around 10psi and increasing it gradually to about 14psi at the top of the rpm." - Craig Cathey

UPDATE:

"I took my car to the drags on Friday night. My best run was 10.485 seconds at 139.32 mph. This pass was made with a strong direct headwind, so I think I should be over 140 mph.  What a night!  I would have posted this earlier, but I was at the Balloon Fiesta in Albuquerque. I drove the NSX there the night of the races.  I was way faster than a lot of drag cars out there and they have to be trailered to the track.  I hope to post a video of the run. I'll see what I can do." - Craig

"The kit that I purchased from HP has very high quality parts, the piping is heat coated, and the wastegate location is placed nicely beside the turbo. All in all this was my favorite modification to the car, and I highly recommend this kit to any NSX owner. It is priced very very well for what your getting. YOU WON'T BE DISAPPOINTED!!!" - Omer Arshi, owner, Canada's first HP Turbo NSX
