what do you guys think? something that would be useful in our cars, maybe? the motor could somehow be connected to the turbo shaft somehow. i was thinking that the motor engagement could be rigged up to the accelerator pedal. it would click on as soon as the pedal was stepped on, spin the turbo up, and then click off as soon as the engine spools the turbo beyond the electric motor’s rpm range. the process would be repeated during each gear engagement as the electrical motor would reset itself when the accelerator is depressed. maybe get a motor that has a starter type engagement mechanism to stop parasitic power loss?
i was thinking that i’d be easier to retrofit existing turbo kits this way. seems alot easier…? this idea just popped into my head after reading the supercharger thread and how someone (tegboi?) missed having instant boost…
how fast does an f1 car spin upto? there are some small motors that can easily spin upto at least 200,000 rpm. i guess it would depend on the turbo. i read somewhere that quite a few turbos (t3) produce maximum boost at about 150,000-170,000 rpm… i am not that well versed on turbos so i really do not know. i do know that there are quite a few electric motors that spin very fast.
at the very least, i think that something like this could be used to get the car into parcial boost which would help the car achieve full boos sooner.
Who knows then… I was way off in my understanding. I thought I had heard someone talking about turbos spinning around 20,000 RPM.
You’re on your own my friend, I have no idea.
EDIT:
Shit, scratch that… I remember hearing somewhere that they spin at close to 100,000 RPM. I think the 20,000 RPM figure was where they start to have measurable compression.
Why not? Because your interfooler works by convective heat transfer… which requires flow over the fin elements. Sitting there stationary with lots and lots of heat passing through the turbo but no airflow over the interfooler is no bueno.
