Original Question: In regards to the Ninja H2 full exhaust system, what type of gains could I expect over my current setup? Here are a list of my mods; No Cat & Slip-on, ECU Flash (14K rev limit), DNA Filter, PC5 Tuned. It made 186hp with a 1.21 correction factor in Albuquerque stock and 238hp with my current mods (1.19 correction factor). What gains will the full system net me?
I wish I could give you a solid XXX answer… but it’s not possible. I can’t compare (in good faith) something that we have never tested (your pipe, your flash etc.) to our combination. I can tell you that the correction factors you are quoting – 1.21, 1.19 etc, are not like anything we have ever seen? On our worst day (100+ degrees and 90% humidity), we are at 1.06 – with near perfect conditions (today 60 degrees/ 15%) we are at 1.00/1.01. Of course, our actual altitude is only 860 ft, but something still seems off? That’s a huge difference. When we would travel to Florida with our portable dyno, to sea level (better in cool air with high pressure), our CF would drop to .98/.99. I can say that your ‘relative’ gains of 52 HP seem a bit low. Not sure if it’s altitude, tune, product selection? And I would not be being honest if I tried. All I can say is that we did our homework. I personally spent about 12 weeks on the dyno/designing/testing and then we backed it up with the fastest pass in official LSR competition by any H2 or H2R. If that means we would make better numbers on your dyno… then sweet! If you asked me if I believe that our combination and knowledge will make you as fast as possible in the real world? – then the answer is yes. I hope this helps, Brock
