PFS did not blow up my car! Twins did!
 

Yup you heard it right. After pulling everything apart last night (almost) I found that the stock twins failed. The seals just gave out and started to puke oil real bad.:( I am very upset about this and wish I had kept a better eye on them but they boosted so well I did not even think of it. Well I have a spare set that is in excellent shape and will put those on for the time being and then I will go single after the break in peroid. So just in case you were not following my other thread this is just an F.Y.I.

How is my type'n getting better?

yeah man, the typings getting better. lol. dude, thats crazy about those twins. you should send them to bryan at bnr. he might be able to rebuild them for you. hes really good. but if your going single i guess it doesnt really matter, huh. well, have fun man. what kind of apex seals are you gonna put in your new engine?

I think PFS uses stock seals but a better spring but not really sure. I will find out to let you guys no.

Yeah right you know peter blew up your engine and brainwashed you to believing that it was your twins so you would spend more money.

The other day I saw peter with a pitchfork horns and a tail. :devil:

:rofl:

Don't want to get involved.. but I doubt your turbos puking oil killed your engine.

Disclaimer: Please note the above comment was meant to be humorous. I have no knowledge of peter or any of his buisness dealinggs or shop practices. I just think the whole peter anti peter argument is funny. :)

my TII was puking oil from the turbo for like the entire time i had it with the stock turbo. the engine never popped with the shot turbo on it..... interesting

"enough" oil could burn up and turn in to too much carbon for the seals to pass over. i could see it happening. or maybe they were seizing up and putting too much back pressure on the enigne due to a loss of oil. i dunno.

No. No. No.
The motor was blown from being lean that is correct but all the oil from the turbo's caused it too lean out. I had been adding 1 quart to every fill up for about 3 weeks prior to the tuning and after taking several rides at the BBQ it just went "poof" too much oil lowers octane does it not? Yes it does tell me I am wrong I will flame you hard as $hit.....

75 miles to the BBQ and making 3 runs with 6 high boost runs back to back with proper cooling times just took its toll. I used 1 1/2 quarts of oil in 75 miles from my findings last night. Tell me that is not alot of oil for 75 miles. I topped it off before the BBQ and got the car home and 1 1/2 quarts low. that is bad and the turbos show it aswell.


-Ryan

You are wrong :p:

J/K

1 qt / 1000 miles is ok. 1.5 qt / 75 miles is NOT ok. :(

Sorry to hear about your loss Rikki, but sounds like you have things under control and will be back on the road, stronger than ever real soon!!!

and you did not see anything wrong with this? I think I would have stopped driving it and found the culprit b4 the motor went. Hmm....

Isn't octane the resistance to burn? If so then I can see oil raising the octane, ie making the air/fuel mixture harder to ignite.

Also where was the oil coming from? The exhaust side, the intake side? The exhaust side would give lots of smoke and not affect anything in the combustion chamber.

The intake side would get oil into the combustion chamber but the oil wouldn't really mix with the air/fuel mixture making it lean. Lean implies that not enough fuel was being added for the amount of boost you were running. The same amount of fuel was being injected, your turbos were just adding oil.

If your car was using 1 quart/tank of gas you should have seen LOTS OF SMOKE. Driving the car like that is just asking for something more major to happen. Heavy oil consumption/smoke indicates something is not working to spec, driving the car, especially driving it hard is asking for a failure.

hurley has a better seal out now. im going to be using their seals when i rebuild mine.

This brings up a good question. Just what effect does excessive oil burned in a rotary have on a wideband O2 while tuning.

I'm not inclined to experiment on my wideband to find out.

Anyone?

i go through about a quart every 500 miles but i have a pesky little oil leak somewhere.

No Octane is the restance to DETONATION diesel fuel is OIL and detonates real easy (thats why diesels don't have any sprkplugs or ignition system!) oil does LOWER octane!

I felt there was a problem but did not think they would go out at the BBQ I was planning on swapping them this weekend but now I am doing a motor too:( Ask FD3Boost he was going to give me a hand doing it. I new it was a problem but I did not think they would just blow out (so to speak) that quick. I am causious when I drive her trust me but when I am sure that the turbos just went out because of the heat from that day! I t just took a toll on them what can I say it was stupid in my part to drive it so dam hard but hey all is good so you can flame me all you want. But I knew what was going on but to be honest I have never seen a set just go bad that quick. I have seen a lot of shit turbos in my time but nothing this extreme.

Thank you

Ever seen what the compression ratio on a diesel? On the order of 17-22:1. That is why diesel ignites REAL EASY. Diesel does not burn as easily as gas, ever try and light it on fire? Ever light gas on fire (stand back)?

Detonation occurs when the air fuel mixture self ignites, self ignition occurs more easily with fuels that burn easily. Since higher octane indicates a resistance to detonation then I can't see how adding oil makes gas burn more easily.

Explain yourself or show me some proof.

i'm waiting to see the outcome of this. i don't know if it will lower octane or not but i'd like to find out :)

A few scenerio's that I thought of:

I remember the one plug I saw looked real caked up with carbon. I could believe that excessive carbon build up could cause detonation by having a small fragment of carbon glowing hot and ignite the incoming mixture too early. It happens quite often in piston motors with excessive carbon build up, but they will just "ping".

On the other hand, you were running the car hard (I think), and may have had the carbon break loose and bind up an apex causing it to break. When my N/A motor went last year, it was while putting the car on the trailer to come home from an event. I doubt it cut loose 100% at that time, but I suspect that I damaged an apex much earlier that weekend racing and it finally cut loose much later.

I know that oil will cause the octane rating to drop, but I'd expect to see a large amount of smoke if your motor was ingesting that amount of oil. However, I never saw what was comming out your tailpipe while you were boosting.

It would be great if the old motor could be torn down to get more evidence, but I bet you have a lot of carbon build up in the motor. On a side note, your oil looked dark and is also an indication of carbon build up. Check through the exhaust ports when you get it out.

My $.02. I know nothing about turbo motors.

PS - get rid of that POS Fram filter!

I wouldn't ever use one, but I hear the newer Fram filters are pretty good. :)

I use a Fram :(
