SilverSoop Posted May 28, 2008 Share Posted May 28, 2008 Will double decat increase Exhaust Noise?? Yeh most definetely! The exhaust no longer has the catalysts to restrict power and noise and without them, the exhaust is freeflowing...like mine hehe... Quote Link to comment Share on other sites More sharing options...
Guigsy Posted May 28, 2008 Share Posted May 28, 2008 UK's with a vent to atmosphere DV fitted should do it when double decatted with a decent exhaust system. when i come off full boost mine gives almost a very quiet "pop"/rumble noise which does sound to me like it could be a lick of flame... but im always in the car so cant tell Quote Link to comment Share on other sites More sharing options...
Daston Posted May 28, 2008 Share Posted May 28, 2008 mine will pop a little on lift off however it will bang quite happily on the limiter Quote Link to comment Share on other sites More sharing options...
bolarbag Posted May 28, 2008 Share Posted May 28, 2008 I was under the impression that the only way flames come out of the exhaust is if there is unburnt fuel in there. If your're not running a big power set up that is supposed to over fuel to say try and keep temps down in the pistons then, or Antilag (which is turbo homicide) i'd say you car was playing up if i saw it doing that A properly mapped single or anycar shouldnt overfuel to the extent where there are flames popping out the exhaust, the 'overfueling' only occurs under high load to prevent detonation as combustion temps rise Oem cars overfuel to start with Quote Link to comment Share on other sites More sharing options...

Spending 50 - 180k I would expect it to be mapped properly Quote Link to comment Share on other sites More sharing options...

kosmic Posted May 28, 2008 Share Posted May 28, 2008 your answer is the "Bee R rev limiter" http://www.neweraparts.com/Default.aspx?tabid=54&List=0&ProductID=17 http://uk.search.yahoo.com/search;_ylt=A1f4cflbyT1IN.0AU7dLBQx.?p=bee+r+rev+limiter&y=Search&fr=yfp-t-501&ei=UTF-8&rd=r1 Quote Link to comment Share on other sites More sharing options...
bmx1lew Posted May 28, 2008 Share Posted May 28, 2008 With the Bee R could you get the same effect as this with bpu? surley its bad for the turbos, I have read on here that people have blown turbos due to the Aem Anti lag systems?

bmx1lew Posted May 28, 2008 Share Posted May 28, 2008 Nice, I remember when jay reved the crap out of his, the first pop noise not half made me jump but i felt it aswell, was like some one tapped me on the chest with a bat. Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted May 28, 2008 Share Posted May 28, 2008 Any turbo car can be mapped to make flames on the over run, whether you want to deliberately do this is a different matter. Excess fuel in the right map area with retarded ignition will do it. With fuel costs as they are do you really want to do this? Quote Link to comment Share on other sites More sharing options...

Darragh Posted May 29, 2008 Share Posted May 29, 2008 bee r rev limiters are fun lol although mine kinda cooked my piston rings doh but i used to make people duck for cover when i hit it and the best was i had it set at a low rpm so i wasnt reving the nuts off her Quote Link to comment Share on other sites More sharing options...
supra_aero Posted July 9, 2008 Share Posted July 9, 2008 resurrecting an old thread but I think flames are v.cool coming out of an exhaust when on the loud pedal (so long as its not due to a flame kit but raw brute power). I didn't realise BPU supes generally dont flame I was looking forward to it as well. Quote Link to comment Share on other sites More sharing options...
L33 Posted July 9, 2008 Share Posted July 9, 2008 so where can u get that beer r kit or what ever its called from? my mates s14 used to back fire and a huge pop when he changed gear as the dump valve went off, sounded nuts Quote Link to comment Share on other sites More sharing options...
