jason m Posted February 12, 2004 Share Posted February 12, 2004 I still have my first cat in but with an HKS/TDI second cat pipe and a Veilside exhaust. I had 1.2 bar boost in 3rd in the cold weather and 1.2 in 4th now - any other combos of decat pipe and exhaust and the boost you get ? I'm guessing that this is high boost for 1 cat still in and due to the lagre dia. straight piping (of my bits) Link to comment Share on other sites More sharing options...
CJ Posted February 12, 2004 Share Posted February 12, 2004 Jason Are you running a boost controler? I have a straight through zaust with no cats and a Blitz boost controler. When i set it on channel 4 (maximum level) I get around 1.2 bar with peaks of 1.3 in the cold weather. Link to comment Share on other sites More sharing options...
jason m Posted February 12, 2004 Author Share Posted February 12, 2004 No Boost controller - just my foot and my Defi beeping ! If I am at 1.2 bar anyway I cant see the point of a boost controller - don't want to restrict and then raise boost ? Am going up to Leon this afternoon to get 1st cat out CW restrictor ring and fuel pump done - and I feel some clear front indicators coming on...

Patrick_Devlin Posted February 12, 2004 Share Posted February 12, 2004 If your getting 1.2 with the first cat still in you will definitely get more with it out. Get Leon to change the restrictor ring. I got 1.4 to 1.5 bar without the restrictor ring and still on very cold mornings I get that, but normally I get 1.2 max.

mawby Posted February 12, 2004 Share Posted February 12, 2004 I too have only the second cat out and performance exhaust, and I also get 1.2-1.3 bar boost without a boost controller. Link to comment Share on other sites More sharing options...

jason m Posted February 12, 2004 Author Share Posted February 12, 2004 I don't have a restrictor in at the mo - but have one for fitting from CW based on the 1.2 bar info above so I hope it will be ok - am sure Leon will sort me out. Link to comment Share on other sites More sharing options...
