Ok thanks for the heads up. I don’t use it often. Perhaps 2-3 times a year
Velocity stacks or not?

I saw that part at 9:55. My issue is that there was no overlay of the most important claim in the video. Your observation regarding wheel hop on the MWR graph is fair but a similar behavior seems to have happened with Carbon Smith, and maybe there is 4hp across the curve with CS vs MWR, but it's anecdotal until we seem them as overlay.
The Stringer stacks have a piggyback 'CPU' that takes the RPM signal of the bike to manage a servo; therefore, the servo actuates based on the RPM (tach) signal. I don't know what they are made of...

so what's the verdict here? do I need to run out and find a used portable drill and break it down and make some articulating stacks for da Boosa or do I even need to worry bout that extree 1-2 hp to get around 99.9% of all bikes out there ...

yes they are
Sorry NM I see it now lol
Sweet! Did you get more power throughout the whole band or did it just shift the power to different rpm?

190ish, not too bad.. I wouldn't know what to do with 200hp, not many straights that long, well unless yea nope
What did they cost you? Did you put them in yourself?
Yea man! More power the better! I’m thinking of getting a Ducati or a Honda CBR SP cause they put out over 200 to the wheel! 🤤🤤
And Here in GA we got some nice straights!
they cost around 500$ and they are very simple to install.
regarding the 190whp, they are hard to put the power on the ground, except if you only do road racing.. You wont notice a big difference between 190whp and 200whp, the biggest difference imo is engine and frame behavior..
Thanks for the info. We do roll on racing every weekend! 😜 Weather permitting of course.

welp, packed out in 6th with 190 imma lil' more concerned with braking honestly..
We do it on a long safe stretch. Just make sure you find something similar. And I have to say the Brembo brake pads have been good!
For sure, braking is as important as power.. I installed Brembo rcs19 corsacorta + hel lines + zcoo ceramic pads
Very nice. So far the stock system has been sufficient. 💪🏻

stock is OK until you try braking from 185 to 35 every 2.29 seconds with a lot of hard braking in between, I've never had a stock setup hold up at the track, lest not since like 1999 or so when the speed dramatically increased and the time it took to get there reduced significantly

i would not use MWR stacks with MR12. - no question but 99% of street dont use MR12

that is a cold engine/ tire vs a warm engine/tire not a good comparison. - it should have a little loss then the 5hp should be at the top only (above 13k rpm)

here you go - just grabbed 3 runs from my tests not sure if it was the same 3 but
red= carbon smith - not dimpled
green = stock
blue = mwr
remember i am not trying to sell anything..... i have never sold any velocity stacks from this page.
still waiting on a set to test.......
