UltraFlynn Posted December 23, 2005 Share Posted December 23, 2005 How have you gone about upping the boost without a boost controller? Link to comment Share on other sites More sharing options...
supRo Posted December 23, 2005 Share Posted December 23, 2005 You'll piss on a Skyline GTR!! (standard) Mate- what was the problem you had again and how did you fix it? Cheers, Ro Link to comment Share on other sites More sharing options...
supRo Posted December 23, 2005 Share Posted December 23, 2005 How have you gone about upping the boost without a boost controller? De-catting a jap spec can cause the boost to go upto 1.5 bar! so most people use a restrictor ring to bring it down. Link to comment Share on other sites More sharing options...
UltraFlynn Posted December 23, 2005 Share Posted December 23, 2005 I'm down to one cat and have a bleed valve .... so if I removed the other cat would that make the bleed valve redundant? Link to comment Share on other sites More sharing options...
chilli Posted December 23, 2005 Share Posted December 23, 2005 well done you won't regret it, I'm still loving mine! you around the 1.2bar mark? Link to comment Share on other sites More sharing options...
chilli Posted December 23, 2005 Share Posted December 23, 2005 I'm down to one cat and have a bleed valve .... so if I removed the other cat would that make the bleed valve redundant? yep you wont need it with no cats, you need the oposite i.e. restrictor ring Link to comment Share on other sites More sharing options...
supRo Posted December 23, 2005 Share Posted December 23, 2005 Flynn - you may want to restrict the car to say 1 bar and use the bleed valve to up the boost when required. Some members do that. I use an electric boost controller - normally switched off (1.0 bar) - car is 'safer/easier' to drive - turbos don't spool up as quick. When I fancy a play, then at a press of a button I get 1.2 bar! Makes it more fun as with no matter what power you have, you get used to it - this way I get more enjoyment! Link to comment Share on other sites More sharing options...
Clarkey Posted December 23, 2005 Share Posted December 23, 2005 as with no matter what power you have, you get used to it Indeed. My boost is 1.1 Bar .. bored now. Want to go to 1.4 Bar. Link to comment Share on other sites More sharing options...
chilli Posted December 23, 2005 Share Posted December 23, 2005 I was going to do that, but figured I'd have it set on max anyway so for the price of a decent ebc it's a bit of a waste that I could spend on something I really would use, like rltc or something. I'm learning to excercise restraint with the right foot lol, that's my control... Link to comment Share on other sites More sharing options...
ADD Posted December 24, 2005 Author Share Posted December 24, 2005 sorry for the delayed response i fell asleep (on the computer) i had 2 iffy turbos (supRO, thats what you said it might be) so i have had them changed and now she flys (thanks a million paul) Link to comment Share on other sites More sharing options...

Sub_Culture Posted December 24, 2005 Share Posted December 24, 2005 Im sure there are experts that know better, but from my experience of turbo'd cars and uppping boost pressure, decat pipes etc, it normally means your spark plugs are shagged. Upgrade for some high performance ones and you should notice a good improvement. Andy Link to comment Share on other sites More sharing options...
chilli Posted December 24, 2005 Share Posted December 24, 2005 well from add's sig he is using IK24's, they are pretty good arn't they (think that's what's in mine) and they work ok I get popping on over-run, think it's the lack of backpressure. You get popping on full boost? doesn't sound right, is the power delivery smooth? Link to comment Share on other sites More sharing options...

I had wondered why some people get rid of both cats and some keep them. Looking forward to getting my FCD refitted and then I'll be back up to BPU again.

piehound Posted December 25, 2005 Share Posted December 25, 2005 so on a uk spec you just decat to get the bpu, no ring no bleed valve nothing? Link to comment Share on other sites More sharing options...
Scoboblio Posted December 25, 2005 Share Posted December 25, 2005 On a UK you also need some form of boost controller to up the boost to 1.2bar.... as I believe the wastegate can handle the pressure unlike the J-spec, which will boost until destruction!
