Hi I have a bugeye and its started to det after about 5.5k revs. Has anybody else had a similar problem or advise what to check.
I know it's bad so im not boosting it high until it gets fixed. Car is almost standard just has cat back exhuast filter and electronic boost controller
Thanks john

 

remove the electronic boost controller and get it mapped properly imo

 

So youve upped the boost without any fueling changes? Its worth looking at the fuel pressure. Maybe the pump is tired.

 

hi thanks for replys but i have owned the car for over a year its running less than 1 bar of boost and this is a new problem. Nothing has been changed boost has not been increased this is how it has been since i brought it. Im only using it on low boost to be safe.
Yeah i was wondering about fuel pump it has done a lot of miles

 

get it to a specialist and on a dyno, find out what the map is doing.

Also how do you know its detting?

 

Can hear it

 

Wow if you can hear it by ear as above get it looked at pretty quickly

 

Check the pipe that goes from the inlet to the fuel pressure reg, they can fail and drop fuel pressure.

 

Hi thanks will check that pipe tomorrow

 

also check for splits in the inlet pipe.. seeing more and more with splits

 

And that the CAT in the up-pipe hasn't melted severely blocking the flow of exhaust gasses, very common failure.

 

checked the pipes but all seem ok
