why do f1 cars backfire so much?

[smiffy180]

I know its probably a silly question and i should know this but why do they backfire so much? Especially when slowing down for a corner. I know its to do with no cats but thats about it
Also could you do it in a road car? Would sound epic if you could

I'd imagine it's to do with keeping temps down in the cylinder off the over run and the fact they don't have exhausts, just a 4-1 manifold on each side

Highly strung engines, high compression, lots of fuel being used so lots of heat and exhaust gas coming out means even more heat, lots of fuel on a closing throttle to cool the cylinders, meaning plenty of vapour coming out of the exhaust valves and straight on scorching hot, unsilenced exhaust tubes. I think that's probably about right!

They sound great, but not as good as the F1 cars of old imo. I did like the Dalek noise the blown diffusers created, but they covered up a lot of backfire noise, which is also lovely.

I think they just need a good service.
