Guest Dante Posted May 18, 2007 Share Posted May 18, 2007 Hia! Got a strange boost problem. When i floor the pedal on 3,4 or 5th gear and just when the second Turbo comes online i first get the regular boost drop and just before it reaches max load (0,8bar) the boost jumps up and down between 0,6-0,8 for a short while (2-3 seconds) and after that it stays still at 0,8 untill redline. Any ideas? :S My plugs are BCP7ES gapped to 0,9mm (new from couple days ago). Car is a Jap-spec, dynoes to 315Hk and boost is about 0,8. Link to comment Share on other sites More sharing options...

edge Posted May 19, 2007 Share Posted May 19, 2007 I had a similar problem. Check all the little black rubber hoses above the heatsheild and down at the front just behind the fan Link to comment Share on other sites More sharing options...
edge Posted May 19, 2007 Share Posted May 19, 2007 they looked ok until i took them off, Some had spilts at the ends and some had holes that had become wider. Link to comment Share on other sites More sharing options...

JohnA Posted May 20, 2007 Share Posted May 20, 2007 ...the regular boost drop and just before it reaches max load (0,8bar) the boost jumps up and down between 0,6-0,8 for a short while (2-3 seconds) and after that it stays still at 0,8 untill redline. ... What exactly is the regular boost drop? On a stock setup there is no such thing. As said, I'd first try replacing the vacuum hoses all around the actuators and VSVs.

And Edge, they look okay but i'll take them off and have a closer look then, thnx for the tip. Link to comment Share on other sites More sharing options...
