M1000 Meltdown Fuel or Air???

[The Kickass One]

Second ride out riding a twisted turbo on a 2007 M1000 - New to me this year. 1500 miles on the motor and 500km +/- on the motor boosted at 5 to 6 lbs. Running Amsoil Interceptor Synthethic at 40:1. Gauge reading 12.8 at 2000metres 6600ft

Rings melted to piston on clutch side jug. Jug is toast. Other piston and jug side looks good, maybe little lean.

Chevron 94 octane was the fuel used on the 2 trips this year.
Radium Hot Spings, BC

My question to the turbo Gods. Am I riding the wrong fuel on a pump gas Twisted, wrong ratio or what? Any information is useful information

1st ride was fine and the 2nd ride meltdown!!!

I'm not pissed at anyone, just wondering if I should be pissed at myself with wrong fuel.

Sounds like crappy fuel,

Never trusted pump fuel octain unless your buddy tries if fist.

Is the fuel oxygenated or ethanol blend? Pics of the piston and cylinder?

I believe it may be oxygenated fuel. Piston pics attached, the cylinder has been sent away.

So far, it's the fuel and detonation that I've heard as the crime plus air ratio to high at 12.8

weve had it happen before with chevron 94. would definitly say its a fuel problem.

 

[zebiraross]

Pump fuel + 12.8 a/f ratio=detonation.

 

[Snowstar]

Stay away from oxygenated fuels.

Have you asked Shain? He seems pretty strong on customer service & would likely be the best source for info.

As for the comments about fuel... He bought a PUMP gas turbo, but all you guys are saying he shouldn't buy pump gas fuel .

We can't even get 94 here (91 max), we also can't get non oxygenated or ethanol fuel, so are you saying we can't run pump gas at all, or that we just would need to run a lower a/f rate?

Interesting pics. Sneaking in on your thread a bit, but I am wondering if someone could answer why would the piston damage be over the wrist pin? All of the failures I have ever seen have been predominately exhaust port side???

Also what is a good AF ratio for a turbo? Different for PG or Race?

It looks like a Oiling issue. Most of the deto that I have seen due to lean conditions have occured on the exhaust port side. Never above the wrist pin.

Two years ago, an oil injection pump went out and didn't send enough oil and it deto'd in the same spot, above the wrist pin. It was assumed there wasn't enough oil on that side of the piston, and it got red hot and caused the motor to predetonate and melt that side of the piston, where the heat was created.

I used Amsoil interseptor for the first time wednesday and mixed it 40:1. I was running 12.5 LBS of boost, and was running 112 Octane Sonoco (which is great fuel), and deto'd. AFR was 12.4 ect. Tuning was a little off, but not enough to deto...was on the flats, and no real load on the motor. I believe it was Interseptor oil, and will be switching to Redline.

After all, Hatchers, product tester and the rest of the Twisted Nation swear by it.


I am not saying it was only the oil, but more likely a combination of poor fuel, poor oil, ect.

 

[RACINSTATION]

A/F a bit lean.

Signs of detonation all over the piston.

Oxygenated fuel....avoid at all costs.

How many LBS of boost?

I would NOT recommend Amsoil. Dry,dry,dry......


Redline is awesome.

and will be switching to Redline.

i need to get some pics up of my stock 1400 mile top end, looks brand spankin new, redline syn and sunoco 112 has me sold for life

i also do not mix 40:1.....its closer to 38:1....about 3 more ounces to every 5 gallons of fuel. Sure the sled might bog with with more oil, but it sure as hell wont burn down

Cool...how is Redline on Power Valves? Are they pretty clean or do they require cleaning every so often?

well a/f ratio is the parimeters for burning down...not oil ratio..you could have 20 to 1 and still lean burn..

i agree that some questions need asking and answered...all these pump gas turbos out there and so many time a person is suggested to run higher octane...almost makes sense to sat the heck with it and just buy the race gas turbos..???

Do you run pump gas? If you do what a/f ratio do you run? 12.8 a/f ratio is lean on pump gas.

Previous owner rode with product tester and both indicated to me to run same oil, same fuel and same a/f ratio. I am not out to blame anyone hear. Just asking questions to learn where to go from here as I am installing a new motor this week and really would like to run it safely and not on the edge.

Keep the comments coming

What am I missing here? Only one side burned down and looks like there is no wash at all. Doesn't seem right to blame fuel quality does it? Faulty injector or air leak on that side?

That's what baffled me as well. Here are pics of the other piston
