We worked hard over the winter to improve all facets of our race program, from making our pit area more user friendly to having all our bullets ready for use at the first race. We arrived at South Georgia Motorsports Park on Thursday to test some new fuel strategies with a new engine. After an unsuccessful first burnout and 3 hours we solved the ground lead issue that was keeping us off the track. The engine worked great and we were thinking had some promise until on the last lap of the test session we put the nitrous to it and it wouldn’t shift 3rd gear. We saw a few things we thought could cause the problem, so we worked on it Thursday night. Friday’s test session confirmed the worst and there was trouble in the transmission itself. After a motor swap we were ready for the first qualifying run. We ran a 4.20 with a soft initial tune up, good enough for #5 qualifying spot.

Saturday morning after tuning it up we ran a disappointing 4.19. Looking at the data we found that our more powerful tune up had caused clutch slippage. For the final qualifier we tightened up the clutch and ran 4.14 @ 172 putting us in the 5th position.

First round we dispatched the #12 qualifier Richardo Knight 4.15 to 4.28. Second round would be the McKinney Motorsports entry of Eric McKinney, fresh off a PDRA win last week in Rockingham. Billy got the best of McKinney on the tree and on the track winning with a .014 initiated 4.134 to McKinney’s .023 and 4.166. The #1 qualifier Mark Paquette and the amazingly fast turbo bike would be our competition in the semi final. Our slightly off pace 4.17 would beat his even further off pace 4.37 and we are off to the final round. We hadn’t seen the last of the always tough McKinney Motorsports bikes as we had Ashley Owens in the final. Billy pushed the tree a little too hard posting a -.009 red light ending our day with a runner up finish. All in all a good first outing for 2014!

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. Thanks to Kevin at Lectron Fuel Systems for the awesome new “Injectrons”, Tim at Holley EFI, Ray at MSD Ignition, Jay at APE, Snake & RC at CP-Carrillo, Bill at Robinson Industries, Kerry at Crower, Lori, Debbie, and Melissa at Web Cam, Mike at Cometic, Go Go at Nitrous Express, Kurt at Millennium Technology, Will at Kibblewhite Precision Machining, Carl at ARC, Eric at MTC Engineering, Dave at Worldwide Bearings, Dawn at Bates Leathers, Hot Rod Chrissy for her awesome photos, and last but not least Brandi at for the great coverage of our sport.
