    Lightweight driveshaft

    Great to hear yours held up. This one sheared off at the chain case bearing. BTW, they said I would get a full refund if I sent them the failed drive shaft. You probably could guess, I sent them the drive shaft and they said it was my fault because I overloaded it with power. To each their...

    Lightweight driveshaft

    I ran the BDX light weight shaft and on mine and it didn’t turn out well. It snapped at launch and made a big mess of the chain case. The tune was a big turbo set at 30 psi with a 7 psi launch, about 425hp. The BDX shaft was their high hp version. When I purchased it, I was told it was good...

    2023 SRX in person looks??

    I just picked mine up. There’s a lot of blue! It’s growing on me. Looking forward to trying the power steering this weekend. Sure wish the dash was better, it’s like the dark ages compared to Doo or Polaris.

    Highest Speeds on Sidewinder/Thundercat

    The goal was to make it as quick as my 1200 was. I got close. It’s a lot harder to make these things fast than making them quick. With a bunch of power and decent clutching they will get down the track. I wouldn’t even know where to start trying to get a trail sled up 144 mph…..that’s...

    Highest Speeds on Sidewinder/Thundercat

    Sure, the engine was assembled local. Used the same person who did all the work to my 1200s. The engine builder is the best in the business but I’ve been sworn to keep it quiet. It has all the good internals. Dave at hurricane did a nitro head for me with big cams and +1 valves. He did work...

    Highest Speeds on Sidewinder/Thundercat

    My 2018 RTX isn’t crazy fast but is decently quick. Best 660’ off hard pack snow is 114.8 on GPS. Set up is a pro-mod engine build with a big turbo and TAPP clutching. It’s only geared for 120 at 1:1. This run was max performance pump gas set at 140Kpa, 20.4 psi. I use it as an everyday...

    998 head porting

    You will definitely pick up power by porting the head. My advice is to be careful if you decide to mess with the exhaust ports. Mine ended up in a complete head failure. Exhaust valve port #2 in cylinder 1 was cut too thin. The exhaust port ruptured into the coolant passage. Stick with...

    Steering post

    Yes, sorry I was referring to removing the post. When reinstalling you need to replace the two lower nuts....17mm. One is silver and the other one is gold.

    The two 10mm nuts on the upper steering post bushing.

    Steering post

    I’m in the process of installing a hurricane performance hemi head and to do this I had to remove the steering post. It’s an easy job to get the post in/out. Remove the 2 10mm bolts on the upper collar. Next remove the boost box. From there you will need a 3/8 drive with a long extension (18...

    SRX vs Mach Z does this seem accurate ?

    I love my sidewinders, I have 4 at various tune levels from stock to big turbo. I have had many races against the 900t. The biggest Doo was tuned to 195hp. We have logged at least 25 races against each other. We only race from a dig for 660ft. It runs dead even with my stock tune xtx (141...

    8DN belt on Sidewinder

    Sorry, My favorite was 8JP. With my clutch helix combo. Corrected my post above.

    8DN belt on Sidewinder

    Was able to get a lot of testing the past couple days. Focused on the secondary. Tried three springs and the belts. All with the 46/36 helix. The testing was done on hard pack snow. This was all short distance drag racing. Sled was set at 31 PSI. TAPP/pro4 clutching. Black/purple - Too...

    New Heavy Duty/High performance clutching for My Sidewinder this season

    Clutch temperatures are good. Checked multiple times and they were only warm to the touch. I ordered the purple EPI spring after reading the reply from Sledding Rocks. Hopefully it shows up quickly so I can try it this weekend. I didn’t notice anything on the secondary from the 8DN...
