Billy Vose burns out the MPS 'Busa

The team had been on a week long high after winning the PDRA race at Virginia Motorsports Park. We had no time to rest on our laurels with only a few days to prepare for the Manufacturers Cup’s DME Racing Summer Nationals at South Georgia Motorsports Park. We arrived on Friday with hopes of back to back wins.

In Q1 Billy ran a 4.17 @ 168 MPH, good enough for the #2 spot. For Q2 we added power and lost our grip of the track, running a disappointing 4.210 @ 170 MPH. A few adjustments to help the first 60 feet would net a 4.145 @ 172 MPH in Q3 putting us in the in the #2 spot. With a handle on the 60 foot, we were ready for eliminations on Sunday.

Our first round opponent is Nick Corley. Billy leaves first with a .007 reaction time to Nick’s respectable .043. Turns out we needed every bit of the .036 second starting line advantage when the bike did not want to shift 3rd gear. After rolling out of the throttle Billy was able to finally get it into 3rd gear. Billy’s lead at the stripe was a scant .012 running a 4.36 to Corley’s quicker 4.33.

Since we had a tranny issue in the first round, we made the decision to install another bullet. We had an earned bye in the second round that would let us get a run to get data from the new engine on this racetrack. We ran a 4.161 @ 169 on our bye run.

In the semi final we would race the wicked fast turbo of Mark Paquette. He had just beat #1 qualifier Paul Gast the round before with a 4.11 @ 182 MPH run. This would be a critical lap for us. We poured over all our data to make the best tuning decision possible for this run. Billy’s quick reactions would pay off once again with a .011 light to Paquette’s painful .115. With over a tenth of a second in the bank our 4.136 @ 170 would be enough to get by Mark’s quicker 4.078 @ 195 MPH.

Brunson Grothus had quietly dispatched all the opponents on his side of the ladder to reach the finals. Mike and I put our best final round tune up in our bike and turned Billy loose. The tree flashed, Brunson was off first when our bike abruptly quit running ending our chances against Brunson’s troubled 4.36 @ 163 MPH. We would later find a pin came out of the camshaft destroying the cam sensor and stopping the engine.

We couldn’t be more pleased with the progress of this motorcycle and our team. One win, two runner ups, and a number 1 qualifier in 4 race starts this year!

About the bike: This bike is a totally unique combination for Pro Comp. It starts with a highly modified Suzuki Hayabusa powerplant with an MPS billet block, CP Pistons, Crower rods, Cooper Performance cylinder head with Kibblewhite valves, APE springs and cylinder studs in an Innovative Performance Racing chassis. It features what we call “MPS Lethal Injection,” a combination of MPS Spyder Dry Nitrous system and the new Holley Dominator ECU. This custom EFI/nitrous system controls all motorcycle functions including data logging.

We would also like to thank all our other parts suppliers without whom we could not race.
