Which dyno software are you using? Are you set up to dyno at the propshaft or the crankshaft? In what rpm range did you see the 10hp gain? Are you set up to dyno other motors as well or just the three bangers?

Could you please print and post a dyno spread sheet on this? I would love to see the the torque curves as well as the horsepower. Thanks in advance.
the 56er, far from dead, like all horse power projects it waits on a fat cash injection, witch is slated for it and on it's way. costs a fare amount of cash to run a dyno a day. you can dance around it, talk to it, pour beer on it, mess with the tuna, rejet it, none of those things make horse power. a turbo, super charger, move more volume of mix into the cyl , like more gun powder in the round the bullet goes farther and faster, thats what finger ports do. when done right the rings don't know the finger ports are there. you can move the ring gap but adds cost.

I understand finger ports and how they work. I have seen dyno results on a v6 I was just wondering how the 3 cylinder responded in comparison. I guess there are no dyno results from your response. Not trying to be a jerk I just was curious for comparison no big deal. I'm sure it will run well.
What were the results on the V6?Originally Posted by Freddie Webb
Thanks,

was that a std port engine just with the fingers added?
can you repost attachment
cheers
the smaller triples don't quite get the hit the V6's get from fingers. it's a volume thing. don't take things so hard Freddie, it not there. i don't have stock numbers. so why do all the extra work to find where the ring gap runs, cuzz they are most likely not centered, thats just production made, if you don't center up the ring gap, the pin can get worked lose, then she will just come apart. for the most part a V6 150hp with finger ports is a 190- 200hp.

Sorry the attachment didn't come through. I am not upset Fast Fred I am just trying to figure out where you are getting all these horsepower numbers if you don't have access to a dyno. It's not a big deal I just like data that's all. I wish you well with your project.
