The ecu was a power fc and no it wasnt bouncing off the limiter. It held those revs for a couple of secends then he backed off.

The block was cleaned fairly well as its not the 1st engine ive built but there are a few things that may have givin me contamination. The only thing is the car was driven around for a couple of weeks without a problem before anything happened. Also the car was driven for a day or 2 after it saw the high rpm and it drove without a problem.

As DVSR32 said i should check the oil to maybe find out what the cause was. Not sure as to where i can get this done or how it works exactly but i would really like to find the cuase of my problem.

Maybe i should ask for a 8000rpm- 8500rpm rev limit just in case to help save the engine from the high revs.

Personally I think its a little late for an oil contamination test, the bearing has let go so you are guaranteed to find metal in the oil. Best to pull it down and inspect. Keep a sample of the oil just incase.

As for rev limit, it speaks for itself. Set the limit to the actual limitations of your build.

      If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.

      If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.

      MAJOR FUEL ISSUES 25det neo r32

      By MBS206 · Posted

      Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
