Default direct turbine fuel injection???

i dont know if this is the correct term for it but i heard of some tractor pull tuners using a system of injection where you have fuel injectors that spray fuel directly into the turbochargers turbine housing to basically cause combustion right in the turbine to produce instant full boost pretty much off idle

does anyone know of any type of process like this?

sounds like some type of anti lag system. most systems generate extremely hot gas temps and turbo/mani temps. do it to much, and the turbine/housing will fail sooner.

axial flow gas turbine engine diagram....(turbos are radial flow)


a turbo analyzed

just search for radial flow gas turbines and axial flow gas turbines

that is anti lag

the other way is to retard like ****


either way, egt;s would be toooo damned high...and you'll blow your **** if you do it often,

it's really a lot more complicated than ppl think...and not something to play around with

well im sure it would be a very intracite setup and certainly not streetable for a car and would take a very seriously built turbine housing to handle that type of heat

You're probably thinking of anti-lag. Your ECU dumps in a ton of fuel and cuts back timing a lot, which dumps a lot of un-burnt fuel into the header where it ignites and creates a ton of exhaust heat, spooling the turbo.

WRC cars utilize this type of system for anti-lag. Of course, one of their turbos cost more than a brand new S2000... but's that's really a bargain compared to those $500,000 tranny's.

the misfiring system is superior.
