taffyjason Posted April 5, 2012 Share Posted April 5, 2012 So i now have Berks, Stillen Y Pipe then Japspeed K2 centre and back box. ALL sounds very nice, great burble at idle and really roar's with a nice rasp under acceleration, but not intrusive at cruising speeds. One or two questions though: 1/ It seems a little smoky at startup, is this normal or is it just new cat's wearing in? 2/ Is there any chance the car is now running a little rich now there's less restriction in the Berks? Cheers all Quote Link to comment Share on other sites More sharing options...
coldel Posted April 5, 2012 Share Posted April 5, 2012 Worth the uprev, mine was running lean with Berks+Milltek Quote Link to comment Share on other sites More sharing options...
taffyjason Posted April 5, 2012 Author Share Posted April 5, 2012 did you find it a little smoky? Ive enquired to RS in leeds to have the UpRev what was your overall dyno reading after that lot? Quote Link to comment Share on other sites More sharing options...
Michael robinson Posted April 5, 2012 Share Posted April 5, 2012 Why don't you join the group buy for the uprev at rs might save you a few penny's viewtopic.php?f=33&t=59284&start=15 Quote Link to comment Share on other sites More sharing options...
coldel Posted April 5, 2012 Share Posted April 5, 2012 I had a plenum spacer, plus the above and a stillen intake (not sure if that made it go up or down!) and got an extra 14BHP at the wheels and an extra 17lbft of torque. Doesn't sound much but when you look at the dynos instead of peaks and troughs in the power build through the revs you get a smooth curve which you can certainly feel in the actual drive.

taffyjason Posted April 5, 2012 Author Share Posted April 5, 2012 look forward to getting the uprev then, would appreciate a little faster throttle response, it feels like its being held back sometimes Quote Link to comment Share on other sites More sharing options...
taffyjason Posted April 5, 2012 Author Share Posted April 5, 2012 P.S it does sound lovely though, got two thumbs up already tonight! Quote Link to comment Share on other sites More sharing options...
