You read right.(as far as thermal efficiency is concerned) thermal efficiency = work output/heat in.
work output = heat in - heat out.

therefore, efficiency = (heat in - heat out)/heat in.

so if you reduced the heat out to 0. you would have 100% thermal effiency.

so if the exhaust was the same temp as the intake...you have zero heat leaving..

Note heat in is the heat created from burning fuel.

For a fuel to burn it needs oxygen. You have cold intakes to increase the density of air, and in efi, to allow more fuel to be injected. Note if you get more power from your engine, does not mean it is more efficient...not if efficiency is measured as thermal efficiency.

i'l get yur car to do 0-100 in 3 secs.. it'll cost ya $1000.

"Has any1 had any experience with fitting these or hotdogs to their system, what did it sound like?"

i've fited a hotdog to my exhaust once...it cooked quite nicely on a 5min drive.. it was a cheese sausage with garlic.

I might try a kranski next time
