I seem to have developed a problem under boost, it seems to be more common in higher gears when on full chat.

I lose ALL power for like 1 second, then SOMETIMES there are LOUD pops straight away, but then back to normal.

I thought it may be coil related, Tony C thinks possible spark plug blow-out?

Not testing tony's theory, just wondered if anyone else has had this problem, as it proper shit me up the 1st time, thought the snails head had blown off

Cheers guys!

 

Crank or phase sensor or fuel starvation !!


Spark blow out doesnt usually cause bangs and pops !

 

Overboosting ?

 

Sounds like my Cossie at the moment! Will be keeping an eye on this thread

 

Assuming its a cossie you have

 

car has recently been set up by Karl, so doubt its an afr prob.

Is it hitting the rev limiter ?? Are all the pipes around the turbo / actuator on properly ??

What psi boost it showing ?

 

sounds like you are blowing out the spark or your ingnition amp thats comon 2

 

it gets nowhere near the limiter, a common time is like 90 in 5th lol

all the pipes on fine.

boost is 1.3 - 1.4 spike, 1.1 held.


Thanks for the replies so far guys!
