psymon Posted January 14, 2006 Share Posted January 14, 2006 Guys today I removed the second cat and fitted a Blitz de-cat to my Blitz Nur -spec. I still have the first cat in place.... Went out for a test drive on my private test road:respekt: and floored it. There was a difference, although when I got to 140 leptons there was a jolt. I then backed off. Do you think this may be fuel cut........ I have had 160 leptons registered no probs, but This scared me and I don't want to run into it again. I had a boost gauge fitted but its been removed till I get so new gauges. It was boosting 0.7-.8 max before.... Any help or advise appreciated. J-spec TT Thanks Simon Link to comment Share on other sites More sharing options...
Lucifer Posted January 14, 2006 Share Posted January 14, 2006 Yes most likley fuel cut as the engine was under heavy load at that point. Link to comment Share on other sites More sharing options...
psymon Posted January 14, 2006 Author Share Posted January 14, 2006 So do I just need to buy a fuel cut defender ? The first cat should still restrict the boost well under 1.2 bar. Or am I just stupid Link to comment Share on other sites More sharing options...
Jake Posted January 14, 2006 Share Posted January 14, 2006 Fuel cut occurs at 1.0 bar Link to comment Share on other sites More sharing options...
JohnA Posted January 14, 2006 Share Posted January 14, 2006 Well it has to stay above 1 bar for 3-4 seconds, doesn't it? Plus the boost gauge might be off by one psi or two, so there is some leeway. Link to comment Share on other sites More sharing options...
chilli Posted January 14, 2006 Share Posted January 14, 2006 did lights come on on the dash for a moment? that would be the sign it was fuel cut - sounds like the most likely cause, it was quite violent on mine! recomment the Thor VFCD, easy to fit and works straight out of the box Link to comment Share on other sites More sharing options...
psymon Posted January 14, 2006 Author Share Posted January 14, 2006 Unsure if the lights came on or not, to busy looking at the runway Link to comment Share on other sites More sharing options...
