      I just tossed my thrashin supply exhaust cause the cheep metal they have used in the stainless polished steel can’t take the heat and it’s all spotted went with bassani and they are the one who bends there pipes for them again the AR chamber did nothing in the dyno room

    @BLOCKHEAD I ordered a D&D Bobcat in chrome with the carbon fiber wrapped muffler for my 2022 Low Rider S. They told me it would take 12-14 weeks and I received it in 2 weeks. Jennifer was great to work with. The exhaust tone is incredible and looks awesome on my bike. I saw improved performance without any other significant work, particularly in the mid to top end. I just wish I could go with the Tune I want but I'm preserving my factory warranty for now.

    Killer video love that power and pull from 80 mph to 120+ it was fast. Did you guys stick with OEM oil pump and plate. You Guys should start listing the parts you install. Especially when you get good results like this I’d rock those numbers and be happy all year long. During the tune he said he had to back door the ECM to get past a limiter does the Power Vision not have ability to change the limiter setting? I have a TMax on my 08 Dyna and you can set the limiter. My 22 FXLRST I was going with the PV to find out if one’s better or if both are top notch and this PV versus TMax is more of a Miller Taste Great versus Miller Light Less Filling argument.

    Peak numbers mean jack💩! Look at the area under the curve and when comparing multiple runs incremental area under the curve! This Star cam has an impressive incremental area under the curve...geez look at the torque @6000 rpm, it’s still ~105 lb*ft...still pulling hard at 6000 which wins drag races against your buddies! It just has that little dip early on, maybe it can be tuned out. I speculate that low/mid torque is great due to smaller duration and it maintains top end with the bigger lift and Bryce cams usually open the exhaust valve early to get extra HP up top..... Impressive!

    At 13:18 in the video it’s mentioned that the first pulls represents: cam, lifters, intake, exhaust, and S&S tappet cuffs.
    Did you forget the valve springs that was recommended by the manufacturer for this cam and noted at the beginning 3:08 of the video, or was that not included for part of the first pull? Also, are the anti-reversion pipes 3:18 recommended or a must include for the build?. Curious and I’ve been jotting down the parts list.

    • @palmettolowlife1996
      @palmettolowlife1996 Рік тому +1

      It depends on which meets your riding needs. If you want low to mid range torque go with the 30/30 if what he says in the video and what the chart pulls state. If you don’t want to put a bunch of $ parts into the bike I’d go woods 22xe or 30/30. Gixerfoo has a good video about aftermarket cams in 107s they produce just as good results with stage 2

    • @brandonmatlock8659
      @brandonmatlock8659 Рік тому

      30-30 for sure. You’re gonna feel a nice bump in power from stock. Spending the extra on the springs, injectors, throttle body, etc. to accommodate the F-35A is just like Chris said in the video. Not exactly worth the squeeze. You’re not really gonna be able to tell the difference of 5-10 more hp or torque. At least I can’t after riding my buddies stage 2 with the same mods as mine, his being on a 107 & mine being on a 114. Just make sure you have a good running pipe & air cleaner. Lot of exhausts out there dump all the power.

    You guys should have something extra at the Grand Opening for Blockhead Members. Just a thought 💭
    VIP tour or something 😮

      Great question. Since the heads were removed to change the springs it was definitely a possibility.

    Great video as usual. I am an old guy. Spent so much money modifying cars and motorcycles for more power. Sadly, big horsepower requires big wallets. What I have learned through the years is FORCED INDUCTION, which is expensive, gives most Horsepower for the buck. Future oem bikes will follow the car emissions handbook. From VVT, Forced induction, hybrid to full electric.
