Could you briefly explain how this device helps efficiency?
Is it because there is a little more area that the fuel can atomize?
Just wondering how this idea came about.
Thanks,

Longer runners would actually improve the low/mid range but may sacrifice some of the top end.RacerZX wrote:Very interesting, thanks for the great before and after dyno testing. The longer runners should improve velocity for higher RPM power, but the dyno showed the opposite, odd, not sure what to make of that, but great none the less that there was a measureable improvement.
Not that I'm aware of. All you are doing is adjusting the power curve bringing more power into the mid-range at the expense of the top end. If you look at the dyno graphs on the sellers website I think it's a good trade off because it's not 1 for 1 (so there is an overall gain) and your bring the power into a more useable range. I like being able to have more power and not be WOT.08PathPounder wrote:Are there any longterm cons after having the IMS installed?
