Today, Dyno-Dave walks us through cam testing of the S&S 475 Cam on our 2023 Road Glide Limited shop bike, GoldenRod, and explains the ins and outs of Dyno sheets. JD's Cycle Works is located at 6146 Sullivan trail in Nazareth PA, 18064
Hey Dave, I’m very glad to see you are putting out your own content. It is awesome and I’m sure will only get better. Just wanted to say thank you for the great work you did on my 19 slim. You put a S&S 124 with the TTS 250 cam and the bike rips!! I’ve got a little over 6k miles on it and it runs great! Keep up the good work.
man, I just discovered you started a channel...sweet! I have a 2017 road glide special 107, stage 1 and pv tuner with 105k miles and not one issue yet! Is it ok to drop a S&S 475 cam in it now and do I change springs if so?? thanks!
I wish you lived closer to me you tuned my bike before for another customer of yours and it broke a valve spring among some other things and the guy here re tuned it and I don’t think it’s getting as much power as before It ran better before when you tuned it I might have to come see you sometime and have you fix the tuning but it’s a 19 hour drive
Dave, you started off with saying STD is 4% higher numbers than SAE but your 475 sample runs only shows about 2% between those correction factors. What gives? I’d assume the 2 charts are the same run just printed out in both factors right? Explain the 4% rule you gave but the 2% it actually was.
Wow!! Excellent Dave thank you awesome information!!!!!!!!!! There are many tuners out there that do the quick and dirty tune just to get your $$$$$. Appreciate you!
Great video Dave. That 475 cam has really great horsepower and torque.. it also has a great lope. Really interesting comparing SAE and STD.. found the afr explanation interesting also
Dave installed the S&S 475 in my trike last year and tuned it. Took it out west in June and it really made a difference going over those high mountains fully loaded.
You say “barely any difference” so what’s the difference? I have a Star Racing 30/30 cam and my tuner guy has numerous speed records at Bonneville and my numbers don’t even come close. I have a 2019 CVO Limited with a 117 with Rhinehart exhaust, Cycle Shack exhaust manifold, Star Racing 30/30 (485) cam, and Road Skulls Straight Shot air filter and I’m at 109 HP and 129 torque
@@JDsCycleWorks coming back to this now that you've been adding more cams. They all dip in the same rpm range. I compared to Fuelmoto's cam shootout and they're using a 2-1 setup w no dip. What are your thoughts now that you have more data?
@@JDsCycleWorks the bike is not smooth before I try with 107 than I went with a big bore and its still not smooth. I think 475 over hyped by RU-vidrs…. Its not that good cam there is a better choices for power and M8 smooth driving experience.
I have the S+S 475 in my 2018 CVO with 117 engine. D+D head pipe, SE mufflers, TTS tuner, Arlen Ness air filter element. It only makes 114^ HP, 124^ torque
Your exhaust system will shape the torque curve. I believe the SE mufflers have a mellow tone and are a bit restrictive. This may explain the numbers you are getting. Every bike will breathe differently and have different numbers.
