hadyn Posted December 29, 2004 Share Posted December 29, 2004 Do TT Supras pop flames from the exhaust if you have a decatted large bore exhaust system and a vent to atmosphere dump valve?? I know its a bit childish, but the flames out the back of my S14 200SX on overrun are one of my favourite features Quote Link to comment Share on other sites More sharing options...
tbourner Posted December 29, 2004 Share Posted December 29, 2004 I'm sure I've had flames before, full boost, full throttle, over 7k revs in first and there was a loud bang (shit my pants actually!!). You could always just bugger up your own timing to do it (mind you isn't it because it's 100% duty cycle anyway? I dunno I'm no techie!!).

Matt Harwood Posted December 29, 2004 Share Posted December 29, 2004 That's not real! - That's some saddo with a spark plug up his exhaust! Do it properly! Quote Link to comment Share on other sites More sharing options...
hadyn Posted December 29, 2004 Author Share Posted December 29, 2004 flamer kits are truly lame lads, its all about natural flamage! Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 29, 2004 Share Posted December 29, 2004 Anyone with a proper aftermarket fully mappable ecu should be able to dial in a ton of flames, albeit at a loss of fuel economy! Quote Link to comment Share on other sites More sharing options...
Ian C Posted December 29, 2004 Share Posted December 29, 2004 I think it's something to do with having way too much fuel going in, so when you lift off you get a load of unburnt fuel going down the exhaust and it ignites on the hot bits. I have to confess I've been trying to get the flame effect with the E-Manage, purely just to see if it can be done of course I haven't got too far with it though, other things have taken priority -Ian Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 29, 2004 Share Posted December 29, 2004 Map for retard at mid to high rpm closed throttle and dump plenty of fuel in. Quote Link to comment Share on other sites More sharing options...
Whitelightning Posted December 29, 2004 Share Posted December 29, 2004 Yep, WL flamed badly, scared the poo out of drivers following. They seemed to keep their distance for some reason. Quote Link to comment Share on other sites More sharing options...
Ian C Posted December 29, 2004 Share Posted December 29, 2004 Map for retard What are you saying like? The ignition timing retard is a trick I didn't know, I can back that right off at 6500+rpm and chuck in as much fuel as I can persuade it. So then, if I take it to the limiter and change up, it flames, otherwise it drives normally. Hahaa,it's gonna be interesting testing that! How much would you back off the timing? -Ian Quote Link to comment Share on other sites More sharing options...
dude Posted December 29, 2004 Share Posted December 29, 2004 F**k me Chris not the sort of post i expect to see you in !! Still full of christmas cheer !!! , can you imagine getting Justin Nenni over to map your car and telling him dont worry about the HP just give me flames !!!

By retarding it you will keep EGT's high, by adding fuel you will get flames. if the software allows crank open the IACV fully too, to add air. Basically that's what the WRC cars used to do in the old days to keep the turbo spooled, same in the BTCC when they ran the big output Cosworth Sierras. Now they used to flame a lot....

hadyn Posted February 5, 2005 Author Share Posted February 5, 2005 just been watching Getaway in Stockholm 2 with the black supra allegedly tuned to 450bhp - that supe seems to flame a lot, so surely all supes running vent to atmos bovs and fully decatted must flame too?? Or was this a case of hybrid turbos and aftermarket fuel management causing the flamage? Quote Link to comment Share on other sites More sharing options...
Scoboblio Posted February 5, 2005 Share Posted February 5, 2005 I think if you look at the situations where the supra flames, it does it when the exhaust hits the road because of the low ground clearance. Is it possible that it's the shock generated by this that's igniting the fumes? Quote Link to comment Share on other sites More sharing options...
Jake Posted February 5, 2005 Share Posted February 5, 2005 My decatted RZ auto with stock BOV makes flames at WOT gear changes and when shutting the throttle suddenly at high revs. Quote Link to comment Share on other sites More sharing options...
hadyn Posted February 5, 2005 Author Share Posted February 5, 2005 when you say decatted jake, do you mean fully decatted?? I wouldnt think you could flame with one cat still in Quote Link to comment Share on other sites More sharing options...
Jake Posted February 5, 2005 Share Posted February 5, 2005 Yes, a full catectomy. (I'm talking about my 93 car, the 98 one still has the second cat in place) Quote Link to comment Share on other sites More sharing options...
hadyn Posted February 5, 2005 Author Share Posted February 5, 2005 great is it around £300 for both decat pipes then? and does the restrictor ring actually work stopping you from boosting past 1.2bar? how easy are they to fit? remove cats by bolting off pipes and then refitting the decats?

Jake Posted February 5, 2005 Share Posted February 5, 2005 great is it around £300 for both decat pipes then? Depends what you buy and where from. I had the front decat pipe made and fitted for (IIRC) £125 by a local exhaust specialist (Stealth Systems in Southampton). The car already had the second cat off when I got it. The second decat pipe for the VVTi I bought from CJ for £70. The front decat pipe for the VVTi I get from Terry S second hand for £60 and does the restrictor ring actually work stopping you from boosting past 1.2bar? It does if it's the correct apeture for your car. This is trial and error though. Also it won't boost as high on warm days as it does when the air is cold. how easy are they to fit? remove cats by bolting off pipes and then refitting the decats?Mechanically it's simple enough but undoing corroded exhaust manifold nuts is fraught with protential problems. When doing my VVTi front pipe one of the manifold studs snapped off. Restudding an exhaust manifold in situ is not my idea of fun. Quote Link to comment Share on other sites More sharing options...
