![]() These kits do not contain instructions, they are intended for race technician installation. These stacks are for race use, off road competition use only. I am going to use the unrestricted map with active tune, but was wondering if there are any specific changes I would need to make on AFR to compensate for the stacks My main concern would be for the bike to run more lean with them. Dyno proven gains of up to +8hp Developed 100 in house on simulation software. May 2022 Hello, I have a 2020 R6 with Arrow full exhaust, DNA air filter & EDR Performance velocity stacks. The production stacks are produced with highest quality Onyx + Carbon Fiber reinforcement. The EDR Performance R6 Velocity stack kit for the 2008-2022 models. Colored stacks are a material we use for prototype/testing use. *Please note the stacks are black only! The black is proprietary, extremely high temp >145*c and race fuel resistant. The Material (Fiberglass, kevlar, carbon fiber) is expected to hold 105 deg C as well as exceptional strength to weight ratio. ![]() See the attached dyno charts to help you decide on what Stage works best for you! Fully 3d printed Yamaha R6 Velocity Stacks. These have been shown to produce OVER 15 rwhp on our EDR R636cc superbikes as well! This is perfect for the R6 owner wanting maximum top end power, especially great for long road courses (Think PIR, Road America, Thunderhill, etc) or drag racing. what do they do do you see any difference are they worth it :menace. While our Stage 1 velocity stacks have been proven around the world in dyno shoot outs, roadracing, street bike riding and track days, we wanted to create a design that would produce even more top end and top speed! These stacks provide near stock power levels from idle to 11,000 rpm but REALLY come on from 11,000-16,000 and can produce OVER 12 rwhp at 14,500 rpm. 827 Views 7 Replies 5 Participants Last post by freezer16801, Jan 20, 2007. Stage 2 Hi Rev is our latest upper stack design. Stage 1 is our proven velocity stack design with hundreds sold and used around the world! These give the smoothest power band you can get over any other velocity stack and we see gains of up to 9 rwhp while seeing NO loss of power and torque in the entire power band. This allows the rider a true feel for the throttle giving a more accurate throttle inputs, improves confidence to get on the throttle sooner and boosts rider confidence. EDR Performance velocity stacks provide a smooth power while allowing the bike to continue making power all the way to redline. If so, what is the mechanism for doing so Must they be combined with an after-market exhaust system or a PCIIIR to realize the benefit or will they bring added HP by themselves alone. Our stacks greatly improve torque/HP to smooth power delivery. What do velocity stacks do for the engine My assumption is that they improve air flow to the throttle bodies somehow. Dyno proven gains of up to +8hp! Developed 100% in house on simulation software, produced in house on 1 of our 2 state of the art MarkForged 3D machines and finally backed up on trace track with real world data. The EDR Performance R6 Velocity stack kit for the 2008-2022 models.
