scooby_doo_do Posted March 26, 2004 Share Posted March 26, 2004 I was playing with the bleed valve/Manual boost controller last night to get it on to 1.2 bar. After i adjusted it the first time i was hitting 1 bar and it was fine. So i though i'd put it up just slightly more,. But when i accelerate hard there was like a slight popping sound at about 1.1/1.2 bar when over 4k revs.. Anyone know what this is ? Is it the restrictor ring in the exhaust ? Or is it the race logic stopping wheelspin (as it was slightly damp? I turned the boost back to 1 bar again and all seems fine. Thanks.

SkyJawa Posted March 26, 2004 Share Posted March 26, 2004 Its hard to say by that description mate. Can you describe the popping in any more detail, any particular revs, turbo 2 online etc? Quote Link to comment Share on other sites More sharing options...
scooby_doo_do Posted March 26, 2004 Author Share Posted March 26, 2004 Yep, 3 of us in the car... and i floored it.. in 4th gear second turbo comes on line about 4 4-5k revs and the boost went up to 1.1 and then there was sort of a popping noise from the exhaust - only slightly though.. I didn't notice it at 1 bar.. Is that a little better ? Thanks. Craig, Quote Link to comment Share on other sites More sharing options...
outatime Posted March 26, 2004 Share Posted March 26, 2004 When did you last change your sparkplugs? It could be RLTC cutting in or it might be that your plugs aren't cold enough or need replacing... Quote Link to comment Share on other sites More sharing options...
scooby_doo_do Posted March 26, 2004 Author Share Posted March 26, 2004 Had the car serviced about a month ago...... But the plugs were fine.... I'll try later when the alcohol has warned off with the race logic off. Quote Link to comment Share on other sites More sharing options...
scooby_doo_do Posted March 26, 2004 Author Share Posted March 26, 2004 Just got back in.... Seems the car pulls well, then theres a sort of misfiring sound and a (the only way i can describe it) spluttering noise and the car seems to go a little lumpy and the revs seemed to jump around a little (May jut be lumpy road that though).. - Going to take the bleed valve off tommorrow for my trip to bournemouth as i don't want to damage anything ! Any ideas or should i take it somewhere for someone to take a look..... Oh Mr Wilson.......... Quote Link to comment Share on other sites More sharing options...
dude Posted March 27, 2004 Share Posted March 27, 2004 Turn off the RLTC if it still does it you need some colder/better plugs !!! Dude:flame Dev Quote Link to comment Share on other sites More sharing options...
scooby_doo_do Posted March 27, 2004 Author Share Posted March 27, 2004 Ta Dude.... U don't think its anything to worry about then ? Quote Link to comment Share on other sites More sharing options...
Paul R Posted March 27, 2004 Share Posted March 27, 2004 Hiya, My car has just started to do this again....I changed the plugs for some cheap ones about 2 months ago and that resolved the problem. I'm going to buy some iridium plugs next month when I get the cat taken off. Cheers, Paul. Quote Link to comment Share on other sites More sharing options...
scooby_doo_do Posted March 29, 2004 Author Share Posted March 29, 2004 You think maybe try changing the spark plugs then for a trial to see if that fixes it ? I currently have hks iridiums in the car... What plugs did you get again Paul ? Quote Link to comment Share on other sites More sharing options...
Paul R Posted March 29, 2004 Share Posted March 29, 2004 I had iridium plugs in my car and it was popping like a good un. A set of 15 quid NGK's solved it.....for a couple of months anyhow! Paul. Quote Link to comment Share on other sites More sharing options...
richardharmon Posted March 31, 2004 Share Posted March 31, 2004 I had the same problem, a set of plugs from Chris Wilson sorted it. Quote Link to comment Share on other sites More sharing options...

scooby_doo_do Posted March 31, 2004 Author Share Posted March 31, 2004 yep...turned the race logic off today and floored it.... Absoloutly fine until about 5k in 5th and the wheels started to spin - ever so slightly but was definatly spinning... Not as bad as it was in the damp.... If i'm more gentle with my right foot it's ok.... checked the rear tyres and they still have about 1-2mm of legal tread left.... How on earth can i be spinning up in 5th gear ?? Oh well.. I raised the boost to 1.2 again.... Car flies.... Quote Link to comment Share on other sites More sharing options...
SimonB Posted March 31, 2004 Share Posted March 31, 2004 It's not your clutch slipping rather than the wheels spinning is it? That's exactly where you would expect to notice it if so... Quote Link to comment Share on other sites More sharing options...
scooby_doo_do Posted March 31, 2004 Author Share Posted March 31, 2004 Na, i don't think so... I had the clutch uprated about 2 years ago when it was really slipping.. It use to rev with no pull.... Quote Link to comment Share on other sites More sharing options...
