hadyn Posted February 5, 2005 Author Share Posted February 5, 2005 okay so replacing the second cat(the cat that connects to aftermarket zorst systems) with a decat is pretty simple though apart from corroded bolts? Quote Link to comment Share on other sites More sharing options...
Jake Posted February 5, 2005 Share Posted February 5, 2005 Yeah it's a cakewalk compared to the front pipe. I'd recommend using new nuts and bolts when reassembling. OBTW, Getting a gas tight seal on the joint between the front and second pipe is a pain sometimes, unless you're using the proper gaskets.

hadyn Posted February 5, 2005 Author Share Posted February 5, 2005 well i'll do the second decat in the near future as it seems pretty simple to do, and i'll make sure i use new bolts and gaskets Can you expect much boost gain with the second cat gone??It wont spike over 1.2 bar with only the first cat in place will it?

Jake Posted February 5, 2005 Share Posted February 5, 2005 You'll get more of a difference by removing the front cat. I was only getting about 0.9 bar with just the second replaced and front cat still in place. Quote Link to comment Share on other sites More sharing options...
hadyn Posted February 5, 2005 Author Share Posted February 5, 2005 whats the approx bhp gain with the second cat gone? about 10bhp? Quote Link to comment Share on other sites More sharing options...
Muffleman Posted February 5, 2005 Share Posted February 5, 2005 Must admit to being a little disappointed by the lack of flames from my Supe. My very modded MR2 flames quite happily, and it is louder than you expect ! (Dont know what I expected from an explosion ) But then again, it's a bit more difficult to induce on an auto.

Keith C Posted February 5, 2005 Share Posted February 5, 2005 Mine has done it a few times, didn't know it did until someone else told me! Bone stock apart from decat and bleed valve. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted February 5, 2005 Share Posted February 5, 2005 It was a film, an AMERICAN film! There's enough lies in News at ten, let alone an American film being taken as gospel! For sure a car can be made to flame, but an aftermarket ecu and a lack of regard to economy are really needed. Quote Link to comment Share on other sites More sharing options...

Adam Kindness Posted February 5, 2005 Share Posted February 5, 2005 i used to get flames in my old supra.... when running lower boost and WOT change upto 2nd (auto).... also got one on the limiter (at 1.0bar) on RR.. Skyline takes the pis with flames.... its being a twat overfuling just now (timing is out, or just a boost leak somewhere) but on nearly every gear change with hot exhaust it Pop, BANG Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted February 5, 2005 Share Posted February 5, 2005 I thought getaway in Stockholm was Swedish Thought he was talking about that fast and furious *rap... , my mistake. Flames are but a few keyboard strokes away with a mappable ecu Quote Link to comment Share on other sites More sharing options...
Markie Posted February 6, 2005 Share Posted February 6, 2005 I have not had the opportunity to have someone behind me that I know yet in the dark to let me know if I flame or not.. erm I mean the car ! But she does pop every now and again at gear changes.. Does this pop mean there is flamage? :flame Dev Quote Link to comment Share on other sites More sharing options...
hadyn Posted February 6, 2005 Author Share Posted February 6, 2005 Does this pop mean there is flamage? :flame Dev pops and bangs are usually an indication of early flamage Another good sign is motorists who are tailgaiting you suddenly back off a long long way back , some also flash you as they expect your car to blow up Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted February 7, 2005 Share Posted February 7, 2005 There are perameters on a mappable ECU which enable this, the purple car will shoot flames like you wouldnt believe ( 6ft long x 3ft dia). I can get the black car to flame now with the map ecu, but nothing like the purple car did. Quote Link to comment Share on other sites More sharing options...
Nic Posted February 7, 2005 Share Posted February 7, 2005 Mine use to shoot 4ft flames out the back with a loud bang on over run in 2nd or 3rd gear. This was when I was running with the stock 440cc injectors, with the fuel pressure increased and the e-manage. Perhaps a result of the increased fuel pressure nd high injector duty cycles?? Had bigger injectors fitted, fueling and timing remapped and now don't get any flames, just a bit of burbling on over run. Quote Link to comment Share on other sites More sharing options...
