Now we can see why Ito's engines last so long while others' don't.

Argh, that just makes me mad.

Seeing those screwed up plates makes me all the more happy I found my engine builder. He lets me work in his shop with him as we rebuild my engines and some of my friends engines. We know exactly what the internals look like as everyhing is assembled and exactly what parts are going back into the rebuild. We then test them on a test stand for many hours before they get shipped out or installed into a car.

it hurts to see ppl getting ripped off like that. i say post all the pics you get

That sucks. https://www.nopistons.com/forums/pub...IR#>/angry.png That is why I learned to build my own engines. EEEEhhhhh 11 years under the belt. https://www.nopistons.com/forums/pub...closedeyes.gif I have done my share of at home, in the garage, engine building. heh, heh. https://www.nopistons.com/forums/pub...IR#>/bigok.gif

Hey Art,



I forgot to get your e-mail address yesterday. I will send you the pictures of my rotten PINEAPPLE RACING motor(s).



I need to take more shots at different angles to make sure I get a clear picture on everything. I'm on the orad this week but will be going to clean and more inspection of the parts next weekend.

This engine shows excatly what I'm talking about. When an engine is ported to a wild streetport the sideseal is exposed to the closing edge of the port. If careful pre-caution and proper sideseal clearancing is not done this is what will happen. The sideseal will smack right into the upper closing part of the port and get chewed up like this engine here. I also noticed they ported way into the oilseal tracks. There is no need to port towards the oil seals tracks. no horsepower is gained and smoking could be a problem for the engine if the engine is ported that way.



This happened because the time was not taking to carefully inspect and check the sideseal to port closing clearance. The same thing happens to the apex seals when the rotor housing exhaust port is not beveled for apex seal clearance.



This could have been avoided... again a reliability problem but it was not the engines fault..

I think the posting the pics is/was a good idea. These so called rotary engine builders are hurting our community, hurting the reputation of the rotary engine. It does not matter if someone hears about 100 rotary engines that last for 200K miles or about 300 HP+ reliable builds, people are going to hear the negative over the positive. Its just human nature.



Exposing bad builders will be a good way to keep people from wasting their money and getting burned.

i think pineapple puts out bad 2 rotors, i think they got their reputation on periph port motors and 3 rotors...the stuff that interests rob

BAM!!!!!

Hey you let the cat out on the next set. Thats the worst crap I've seen and I 've been rotor racing since 92'. Hey I have built crappy port jobs for myself but I would never impose mystuff on someone else's dime because its not right. I will and have refered people to guys whom I know stand to much to lose by building expensive garbage.

I engine builder should never let a motor out his shop with out telling a customer

whats up. Let the buyer make the decision on what is his problem and if you can fix it .Your sure as hell dont sell port jobs that the high school hang around did to get experience.

I have had many motors built most I assisted in and just recently I decided to go gambeling.

But I will say, that I soon as the builder received my parts I got a phone call that says it all. He went down a shopping list of what was broken ,burnt and not to spec.

I then called my good friend who built my last motor, its in my car now,( he now rents race cars and doesn't have time to build motors at the track) and asked him about these things that the new guys stated.He agreed and stated why these things would be because of inherent defaults. I gave the new guy a green light and have some confidence based on our conversation....before I spent a dime.

Come on people your getting paid to do it right the 1st time.........
