    redratbike modded collectors dyno results

    well gents my pipes have just completed dyno testing this morning

    i must a say a big thanks to Griff for it was his own bike used for back to back testing ,std,single mod,dual mod collectors





    basically both single and dual modded pipes give you approx 3 bhp at the top end over the standard pipe but its the red (dual mod) that gives the biggest kick in the pants.and right where you really want it 4750 to 6500 rpm .its a 10 bhp increase at most and you will definately be able to feel that in day to day riding

    Griffs bike has a different can and hooked box i know that much..he has a pc3 on it but its not custom mapped to the modded pipe these figures are as is ..bolted on..so with a custom map there could be more power to come

    Have another spare collector in the shed so might put the second link onto it this week , got to have a base run on a dyno with 2 different PCIII maps I have , first was 126 rwhp single blended fuel table , 2nd was a Dual fuel table map 132.6 rwhp still only with my single system with modifed collector & header pipe outlet I made & was running 46psi fuel pressure not the 48-50 I use when Drag racing the bike so very happy with my own tuning & development work over the last 4ys . Be good to get even more mid range not that the bike lacks power there but ya never can have enough .

    Gents,

    i've just had the spec from Griff on his bike......

    the dyno runs were done back to back with no adjustments made in between the changes of collector.

    my bike spec is
    hooked air box kit
    akrapovic silencer
    pc3 usb

    fuellin was adjusted afterwards and more torque was found!

    hope this helps!

    Griff

    just found this info regarding a haga replica ..looks like the modded header delivers more or less this :-)

    Building on the already class-leading performance of the Mille R, the Haga Replica sees a 10 hp increase at 6.500 rpm, and a flatter power curve, over 9.000 rpm with the installation of the competition-grade Akrapovic Exhaust system. Torque is greatly increased with torque curves reaching optimal values 1700 rpm earlier than the standard motor.

    You may have to trim your fairings for the twin pipe mod version. I had to . If anyone wants a photo just ask and Ill put one up.

    But dont let this put you off. This is the best mod for this bike by far
