Pete Posted January 21, 2019 Report Share Posted January 21, 2019 Yes. You need to go to see Pop & Bang, father and son that run Pop & Bang Garage. It’s literally the only way. Tell them Snap & Crackle sent you. Quote Link to comment Share on other sites More sharing options...
mk2 Posted January 21, 2019 Report Share Posted January 21, 2019 Welcome to club lupo! Pop and bang. Mmmm. Seriously?! a car that runs perfectly, generating maximum power runs very very smoothly. Every single molecule of fuel burns to make pressure to push those pistons down. Any popping or banging outside the cylinders does nothing but waste fuel (and power). You really really dont want that... Quote Link to comment Share on other sites More sharing options...
lupo20 Posted January 21, 2019 Author Report Share Posted January 21, 2019 i just want to know if this is posible Quote Link to comment Share on other sites More sharing options...

mk2 Posted January 21, 2019 Report Share Posted January 21, 2019 Yes, it is possible to inject fuel during the wrong period, ignite it late, so it burns in the exhaust. Damages exhaust valves. Need to get rid of the cat. Don't do it... show us some pics of your car Quote Link to comment Share on other sites More sharing options...
lupo20 Posted January 21, 2019 Author Report Share Posted January 21, 2019 got no cat no mid box and a hornet back box Quote Link to comment Share on other sites More sharing options...

Damages exhaust valves. Need to get rid of the cat. Don't do it... show us some pics of your car I'm sure I've seen kits on eBay that basically work by cutting the ignition for a second so fuel is sent through the engine but there's no spark, it's then sent straight down the exhaust pipe where a spark plug is mounted and firing and ignites the fuel. Bang/fire/pop. It truly sounds like one of the dumbest modifications ever and I really don't get it. Quote Link to comment Share on other sites More sharing options...
mk2 Posted January 21, 2019 Report Share Posted January 21, 2019 What ecu r u running? 2nd lambda will be giving wierd readings, so must be chipped already...? Mot passes emissions ok? Quote Link to comment Share on other sites More sharing options...

Sounds like what they do at airshows... inject raw fuel (kerosene) into the exhaust to make white smoke. Quote Link to comment Share on other sites More sharing options...
Rich Posted January 21, 2019 Report Share Posted January 21, 2019 Spark plug wired to individual coil and a switch. Unplug the lambda and boom, fire on demand. Quote Link to comment Share on other sites More sharing options...
