Flat spot at 3000rpm

[benny]

Hey guys!

got a prob with my R32 T, from about 2900 - 3100rpm when driving, the power sort of dies for sec......then picks up.

really annoying for normal driving........any ideas?

thx

1 have you got a big intecooler ?

2 are you running over 10psi ??

if so the turbo sucks heaps of air in while spooling up to fill the cooler and this registers on the AFM as running over 14 psi so feuel cut comes on

once cooler is pressurised the airflow reduces and all is sweet again

to fix this situation get a fuel cut defender installed

thanks for the info!

i'm actually running a standard Intercooler with 12psi

would fuel cut still kick in?

Check the air filter. If you have a pod filter, is it heaps dirty? If so, wash it or buy a new one. If it's stock. clean it also. To see if its the pod causing the trouble, take it off and drive it around the block once or something (dont drive too far or through any dirty areas with it off tho!)

If the lag is gone, it was because the filter is too dirty. This happened in a friends car not long ago, we were wondering why it was going dead at low RPM, it was because the filter was clogged and the engine wasnt breathing properly.....

Standard airbox....though the filter looks fairly old

think i'll change it......might check the plugs too.

thx for the help!
