![]() I'm just so glad i didn't buy the '07 R1 like i was tempted to do a few months back when the hype was out there. The GSXR lost as much as 15 Hp in some spots with no gains anywhere. The Gixxer 1k was not(no PC yet it's an 07) although it was touted by FactoryPro as a Drop-in gain due to the O2 Sensor. The R1 was Dyno tuned & the powerband lost with the stacks. I would think that with stacks you would lose top end and gain mid and lower, It seems to me that they are like the intake on a car the taller the intake the Higher up the power curve the shorter the stack or intake the lower the power curve Last year my cousin in Cali had Factory themselves install and tune his 06 gixxer 1000 and he said the bike was a lot better in the upper midrange, too. I rode the bike before and after and it did wheelies lots easier and had to be more careful on freeway onramps. I haven't looked at how the stockers are.comments?Īs long as y'all don't have any kryptonite/I'm gonna be alright.ĭon't know about the 07 gsxr1000, but the R1 stacks worked a lot better in my friend's bike - the upper midrange was pretty wicked. Supposedly, Bear has made some proto ZX-14 stacks but they're such a pain to install he might not make them. Hope you don't mind if I swing this thread to ZX-14-oriented. They're still hung up on carburetors.Ģ006 Kawasaki ZX-14 Ninja, Red now with mo' Brock's in my lyfeġ991 Yamaha Vmax - Because I need a mule to carry the manhoodĢ002 Ford Lightning - Ford GT Aluminum block engined, 802HP 911TQ now WhippleCharged IMO Factory Pro hasn't been relevant nor innovative since fuel injection became the standard on sportbikes. Oh, Hey guys it's been a while! Gonna try to show my face around here alittle more! Took the Factory Pro stacks out & both bikes were restored to full power.ĭoes anyone have actual dyno results that were positive from these stacks as a mod. I just dynoed 2 bikes, an 07 GSXR1000 & an 04 R1. Dynoed & Taken off the Bike!įactoryPro Velocity Stacks. Hope this proves useful to the esteeemed readers of this forum.FactoryPro Velocity Stacks. The following links are given for further reading and guidance on "40 CFR Section 60.18" If you know the flare gas composition you can calculate the calorific value using any simulator or using the law of proportions calculate the calorific value of the gas for each component and multiply it with the individual mole fraction and add up the individual values to get the total calorific value. V max = maximum velocity as calculated above, ft/s Simplifying the above equation in terms of flare tip diameter we get the following equation:ĭ tip = diameter of the flare tip, inches Q = Volume flow rate of the total gas passing through the flare tip (sum of the main flare gas plus the purge gas), scfm 0.8*vmaxīased on the calculated maximum velocity v max the flare tip daimeter can be easily calculated as follows: The flare tip is designed considering a velocity of 80% of the max. v max up to 400 ft/s is permitted for flare gas having heating value >1000 Btu/scf ![]() v max to be calculated based on above equations for flare gas having heating value between 300-1000 Btu/scfģ. v max not to exceed 60 ft/s for flare gas having heating value of 300 Btu/scfĢ. ![]() V max = maximum permissible velocity at the flare tip, ft/sī v = Heating value of the gas being flared, Btu / scfġ. The flare exit velocity is calculated based on two different equations for steam-assisted flares and air-assisted flares. The United States Environmental Protection Agency provides several guidlelines as well as codes for environmental protection.Ī code of federal regulations (CFR) with the title CFR 40 Section 60.18 provides guidelines for determining the flare exit or tip velocities as a function of the calorific value of the flared gas.
