doesnt seem very low budget lol

[adamkmcneish]

pV = nRT

boost = heat

[mageac]

@wheelin888 diesels are better yes,but not one with pure soot coming out of it, soot means lots of unburnt fuel, which meas TONS of n0x

[wheelin888]

lol let me just say that engine is more eco friendly then the factory one it replaced, the problem is soot is something you can see and therefore is deemed to be worse than gasoline emmissions. Gas engines always get the advantage of "out of sight, out of mind"

diesel? in a corvette? wtf is wrong with you?

[markification]

To all the uninformed black smoke is lots of fun but it is what you get when an engine drops below its optimum air/ fuel ratio, having said that, to make optimum power in a diesel you would want light brown smoke because some excess fuel burns in the turbine on the turbocharger which powers the compressor wheel in the turbo which forces more air into the engine. Once you go past the optimum air fuel ratio you are just wasting fuel and creating high EGT's .

@cummins595959 no, it is not heat related. More fuel means more exhaust which means more boost. Heat is a byproduct.

[cummins595959]

@NVMDSTEvil yes i know it comes from it spining but it the heat expanding in the turbine housing that spin the compressor side of the turbo thats why at say 2500 rpm with no load the turbo is not producing any boost but put a load on more fuel so more heat then the turbo boost comes up

[NVMDSTEvil]

@cummins595959 boost comes from the turbo spinning. There are two impellers (fans for the layman) inside of a turbo. The exhaust side of the turbo is pushed by the exhaust of the motor and turns a shaft which drives the impeller on the intake side of the turbo. Heat is a byproduct of compressing air. The turbo also gets hot due to the exhaust of the motor traveling through it and being restricted by the exhaust impeller in the turbo.
