So, when I bought my car, I didn't have the 5th and 6th ports. The guy who rebuilt the engine didn't put them in. He put in block off plates.

I want them in though, for the better low end. I have an RPM switch coming at the end of november.... damn backorders. But, must mean they are pretty good (summitracing). Anyways, I also bought actuators and the sleeves from IndyParts. And a lumbar pump off ebay.

My first question would be, how much of the intake is going to have to come off to install the sleeves? I want to know so that I can order gaskets, etc. I also plan on getting my secondary injectors cleaned. I think they are sticking. For the injectors, what I am going to have to replace? O-rings?

Second question is regarding the summitracing RPM switch. I read something about it being double the RPM on the switch? Like if I set it to 2000 it won't open till 4000 or something? Anything special about using that RPM switch on a rotary VS. a regular piston engine?

Well, thanks guys. Can't wait to get a little low end back. I plan on getting the pineapple racing sleeves as soon as I can afford it.

 

You have the auxiliary ports, just not the sleeves that go in them. It's kinda hard to take a port out of an engine.

All of it. The LIM has to come off the block. Read the FSM for how to install the sleeves.

O-rings, grommets and insulators. See the FSM for where they go.

Use the same setting as a 4-cyl.

Get them now. They're cheap and they're not worth taking the LIM off twice for.

 

I'm skeptical of them actually working or being worth it...

 

I've heard theyre good for at least a few hp. For the price, I guess its worth it since there's so little to give more HP on an NA.

 

skeptical of them working? they turn a 90 degree turn in the air flow into more of a curve. that makes a difference. expecially on a n/a

 

Is this dyno proven? If so, I'm all for it. I just haven't seen the evidence. If it exists, then by all means, please bring it to my attention.

 

I seem to remember a dyno showing a 2-3 hp gain, or something. I don't recall what it did to the rest of the powerband, so it could help more lower down. No idea where I saw the dyno sheet, though. Again, not much, but anything helps.

 

the burden of proof never falls on the skeptic now, does it?

 

I just did some searching, and Blake (of pineapple) said
If I were pineapple I would actually do the dyno myself to prove the gains, but thats just me. I would think they would sell more if they had an official dyno showing the gains. I am most likely going to use them in my new engine I'm building (well, waiting on money to build) and if I ever dyno it I will try to get a before and after result. Who knows when thats going to be, though.

 

No, not when someone's making claims about a product they're trying to make money off.

I agree.

I'm in no way calling Pineapple liars or false advertisers. I'd just like to see a little proof before I buy something.

Not much, but 3 hp is an improvement..

 

Hahaha. Sorry. Misunderstanding on the 5th and 6th port thing.

I understand they they can't be removed. I meant the sleeves. Sorry.

Lots of information. I guess I will try and save for the pineapple inserts and the money for all the gaskets etc. I do have another month and a half.

I figure, if your going to do it, do it right.

Thanks again guys! Gotta love this board.

 

Couldn't that 3hp be attributed to other factors (temperature, random fluctuations, different gas, etc.)?

 

I wish the pic of the dyno sheet was still good so I could see what the power curve did. Thats also interesting about how the torque curve shifter with the cone filter and CAI. I hadn't really thought of that before.

 

Sure it could.

 

Of course it doesn't. By definition the burden of proof is always on the person(s) making the claim. Whether in science, engineering, law or whatever, if you claim something, you're the one who has to prove it's true. Would it seem reasonable if I claimed my car could fly and it was up to you to prove that it couldn't?

This is the bit that's always bothered me about these things. It would be very easy for Pineapple to do the necessary testing to conclusively prove (or disprove) the effectiveness of their product, but they never have. "1/4-mile trap speed improvements and second-hand dyno confirmation" is just not good enough IMO. Far too many variables. If they can't offer conclusive proof, skepticism is perfectly justified.

 

Glad somebody shares my point of view. The way I see it, if a company like Pineapple who possess all the tools, knowledge, and equipment to put a car on a dyno and prove it isn't willing to do so... that's not very encouraging to me.

Ideally, I'd like to see them fund a neutral 3rd party to do the testing. I would probably believe Pineapple's results if they ACTUALLY were to prove something they're selling for $50, but I would feel a lot better if a neutral 3rd party did the exact same tests properly.

 

Then again you could argue that for $50 in the middle of a rebuild its worth it even if you only get a few hp out of it. I mean, if you are going to have the engine torn apart already you might as well make any adjustments you need to eek out every last hp. for $50 its not that expensive...

You missed the point. I'm questioning if they give gains, not if they're worth it assuming they DO give gains.

 

Just call Rob (I think thats his name, met him years ago). He seems like a nice person, maybe he will be willing to provide you some data. At that time, you can point out the lack of data on his website.

 

I emailed him. Hopefully we'll get some info soon.

 

There ya go then!

 

i have mine out in my car, the engine is still being broken in tho so i havent been able to see how well the car responds at higher rpm with them out, but at lower rpm it doesnt seem to be too bad unless youre going uphill, ive never driven it with them in but ive heard stories of the pineapple sleeves causing engine failure because of not intalling the sleeves correctly

 

Pineapple (Rob) emailed me back and basically said that: we give a full refund so try them for yourself and if you don't like them, return them for full price, including shipping.



I didn't find it very useful, but whatever.

 

That's an easy promise to make considering very few unsatisfied customers would bother to go through all the hassle of removing them. Very disappointing attitude...
