  • The watercross season is right around the corner! One of the top Straightline water x racers of all time Howie Steenberg pilots Straightline Performance’s first 800R pro stock engines that today still holds the NSSR speed run record for a full body 800 twin. There was a lot of technology in that sled that we still don’t see on the water today. Hydraulic actuating suspension, electronic controlled ignition that can change on the fly, launch control, and more. Who’s going to make the next breakthrough in the water? 🙋‍♂️

  • This @straightline_performance 850 nitrous build killed it all year….
Pushing double the horsepower it came with from the factory….
Stock internals, and a lot of nitrous…. 
This sled never skipped a beat! 30lbs of nitrous sucked through it. Back to Minnesota it goes for some changes 😎

  • Congratulations to Straightline Performance’s team member Shaun Summer for his great finish at the @mesc_race hillfest a couple weeks ago! 1st in the Mod 800 and then taking “King of Kings” at the end of the day on one of Straightline’s Skidoo 800 HO imp engines. 🏆 Great to see the hard work at the shop paying off.  Congrats!

  • We had one of the most decorated speed run racers Rod Spindler on the Straightline chassis dyno in late winter. Rod called Jason (owner of Straightline) looking to improve the performance on one of his 800 XCR’s on Straightline’s chassis dyno. Ended up be a great day with some very experienced tuners, with results that speak for themselves. Rod ran the fastest time on ice after our session. Here’s a quick video of a dyno pull with Rod checking timing at WOT! 🏁

💥 Jason and his team are here to produce results. Get your session booked for your watercross racer, grass dragger or asphalt machine soon!
