| Re: Exhaust flames
I guess it depends on the setup. If you put in fuel on the overun then you get flames. On FI setups you usually cut the fuel on the overrun but if you want the flames program in fueling when the throttle is closed. With a carb run it rich at tickover and set a high tickover - you can get some nice loud pops and bangs in the exhaust pipes as well! Not very green I know but a big V8 and huge carbs and a lead foot isn't either! The best flamer I drove was a Mk1 Sierra Cosworth with a touring car engine that spat 3 foot flames out of a side rectangular exhaust (no muffler) which was 8" by 4". It got some strange looks from the locals as we drove through rural Ireland lanes at a rapid rate (on slicks as well!).
