Brian Jackett Posted November 12, 2001 Share Posted November 12, 2001 Having recently decatted and fitted CW pipes and a super drager I have experienced boost pressures between 1.4 and 1.5 and experience detonation(miss firing) when running hard on the motorway. I know lots have done this mod and I am interested in what you are experiencing. Obviously only people still running stock Turbo's need post here. Also be good if we could keep this on topic. Could people post : 1. type of decat mod (both cats junked etc..) 2. What type of rear box 3. Max boost 4. Are you experiencing Miss fire 5. Have you blown up yet I think this would be interesting.

matt Posted November 12, 2001 Share Posted November 12, 2001 1. Second cat removed with Blitz pipe 2. Dual Drager cat back 3. Never been over 1.2 usually hang around 1 bar 4. No ....... but have replaced plugs with HKS gold plated version 5. No.........but also have HKS FMIC and cold air intake to hopefully keep the charge nice and chilled I'd be interested to hear views on front cat replacement over 2nd cat....as with the DD and the rear cat removed the car doesn't overboost ( I use a bleed valve adjustable from in the car) I wonder if there are any benefits to be had (better spool up )by maybe refitting the 2nd cat and removing the first. Does anyone know if one is more restrictive than another?? Apologies if this is veering O/T Quote Link to comment Share on other sites More sharing options...
francesca Posted November 13, 2001 Share Posted November 13, 2001 1. No cats 2. 5zigen exhaust, 5" tailpipe 3. Will go to 1.6 4. If I let it, at about 1.4. 5. Not yet! trying to be sensible until I can afford FMIC etc. Also have Profec-b boost controller, induction kit, HKS plugs & Blitz dump valve.
