Rob at Pineapple (like everyone says, really nice guy on the phone, straigtforward, helpful, no BS) said about 8 hp on the later model 6-port engines, about 6 or so on the SE engine....though I am confident one or both of my 5/6 ports were not functioning properly, so I'm hoping to gain a little more kick. Chances are yours are do for a cleaning too, if you saw my site you saw how dirty and sticky mine were, and the air tube was clogged as well!

Right on.

6 to 8 HP..... what is pinapple doing to these sleeves to create this type of gain? the stock sleeves are wide open - can anyone explain what exactly this new sleeve is and how it functions above the beyond sleeve?

the sleeves dead end at a right angle, the inserts are radiused to direct the flow of air properly and with less turbulence.

Now that makes sense - I could never figure out what all the talk was about ..... thanks for the info Brownmound

Ah...........Whould that be the little tube that runs about a foot beside my presilecer? You know, the one that is crimped shut and welded at the tip?(lol) I didnt do it, came like that. So I guess my main question is, is it possible that wireing them open could cause flooding? I went down and tried to start it today. I fired for about 2 seconds and flooded again. The actuators are closed now. WTF? Is there something around the actuators that I could have accidentally bumped that would cause flooding?

maybe a vacume leak cause i run with my actuators pulled out its really wide open..and i don't have any problems with fludding

Where's the logic here people?


No, wiring open your 5th & 6th ports will not cause your engine to flood. If it flooded, it flooded for another reason. Maybe it's cold and the engine didn't turn over fast enough? Perhaps you don't have a spark? Perhaps it's just one of those things. Push it down the street and let the clutch out in gear, once or twice and she'll start up with a sputter.

Wiring the ports open may give you a slightly rougher idle, mines a little lumpy, not quite like a bridgeport but you know .. Opening the ports up also is NOT going to make the engine think there's enough air/fuel for 3,500rpm, where's your head? You're just opening up another path for air. Yes, this may allow a little more air to flow in and the computer will see this from the afm and compensate. It's almost neglegable at idle. Lower RPMs will lose a little grunt as some have said, I didn't really notice much difference, but my exhaust didn't have enough back preasure to open the ports anyways and I felt like ditching the air-pump, so, all is well now.

silly guys.

OK, I have a lead on what it might be. I might have a stuck injector. I mean, when it floods, its like pouring in. If I disconnect the injectors and it starts and runs, that means they are leaking bad enough to keep the engine running. If they are leaking, I was also informed of a place that will re-build them for about $50. I'll keep everyone posted. It seems that the fuel problem and the actuators are a coincidence.

Great pics BM. It always helps to have pics before going on any journey. You saved me alot of head scratching.
Also, 25 hp from the exhaust setup + 6-8 hp from upgraded sleeves = 31-33 hp for not too much money spent. Affordable go faster.

Thanks...really it's more of a documentation for myself, friends, and the forum, but if it helps some people figure some things out, cool. I'm putting a little educational tidbits in their to explain some basics to newbies and my buddies who are confused by my mysterious rotating engine.

I've got some more ready to go up in a few days.

Right on.

the real question here is what will have more peak power no sleves or the pineapple ones?? cause mine are ripped out all togather, so i wonder?
