Gainzy Posted September 21, 2011 Share Posted September 21, 2011 Who's had a good power on standard ported mani's? I was gunna upgrade to a ram style mani but I fear the dreaded cracks, the cast iron ones don't crack so i guess am making the best choice, I would like to upgrade the ct9 to the ct9 hybrid so will the ported mani be the best choice? I would be more than happy to settle at 200bhp.thanks guys! Quote Link to post Share on other sites
lukEp Posted September 21, 2011 Share Posted September 21, 2011 A well ported standard mani will do 200bhp im still running the same mani standard ported mani that I've used at 1.2bar on ct9 and 1bar on hybrid ct9 I did only make 163 bhp but I had a problem with my throttle position sensor which was retarding the timing and reducing my hp. You can take a he'll of a lot off a standard mani thee really thick cast mines had three lots of porting so far and still doing its job it needs doing again and will be done and done till it fails to see how much can be took out of it Quote Link to post Share on other sites
