Okay so not the whole rotor
Rear rotor has one face with half compression
Either way I need to swap motors soon
defprun yeah I do need that motor now bro, unless you can find me something better
I switched to premix with this motor I hope that didn't do it in, or using the wrong mix or something
I usually overshoot the mix, I'll add a hare extra. Is it possible that the mixture in the tank will settle after sitting for a few days or something? I don't see why when it's TCW3 cert 2 stroke.
This was a higher milage motor that I fixed up but I didn't crack the compression on the inside, everything else (front cover, other outer block mods) was looked after and brought up to par
S4 6P, rear rotor was the one that blew (Common in S4?).
It had an engine vibration since I put it into this car, RPM related, slight vibration, I told Adam and he had warned me to look into it further and it might be a sign of failure to come. I'm using an aftermarket light flywheel and counterweight, could an imbalance there cause the vibration and in time take out the rotor or something (since the rear was the blown rotor)
Or was the motor just on it's way to begin with?
I don't want to swap in another 6P and have it blow in a month again due to something I hadn't considered..
Right now I'm just thinking motor was on it's way out anyways, it does have some decent mileage on it but compared to how much life other people have gotten out of S4 6Ps, I consider it pretty damn premature.
IDEAS?!

Oh yeah FYI I was winding out 3rd gear and I got to about 5500 RPM and the car virtually "hit-a-wall" and I lost serious power.
Funny how fast it happens, the car was running spectacular and then just like flicking a switch, it had no power. No funny noises or signs as I was winding the motor out, just BAM no power.
It sounds like the porche from getaway in stockholm at 6K RPM on one rotor. LOL

I was using about 250ml to 40 L of fuel
I had read advice from reputable builders (not just at nopistons but articles all over the web), and converted it to metric (little less than ounce per gallon)
I shouldn't be off but if I am then at least I know what the problem was.

As I understood, one ounce per gallon was a race type setup, but I run the car at decent RPM (but cruise at lower RPM), I don't shift at 3k like a grannie when I drive it.
The rotor is definately blown, when it happened I was thinking fuel injector failure, or spark plug failure, wire failure, coilpack failure, something simple
But I pulled over and I have an open element filter, the intake pulse was not the same at all anymore, and pulling the plugs and cranking the engine over brought light that the rear rotor only has one face with a bit of compression. Front rotor runs like a champ? LOL

Yeah suppose to be like 100:1 ratio. Should have plenty of variance there to rule that out. If it were any kind of no spark problem I doubt it could blow, the sparking action to try to ignite fuel or the lack of is where you run into problems. I'd investigate the fuel sytem and make sure its working.
