MST research

[iceiso]

hello, i'm doing a MST research project, and i chose to do something with cars. pretty much, i had to think up of an idea, and it doesn't have to be financially feasible and i don't have to build it.

this is my plan on making a turbocharged car with no lag...

i was thinking, could you put a small airpump with a tank after the exhaust manifold and before the turbo, and whenever the car idles, the air pump pressurizes some exhaust air into the tank. to overcome the problem is the car isn't idle (say, at a light) long enough, air can also be redirected from the BOV and into the airtank. so, whenever throttle is applied, some air rushes out of the air tank and through the turbo, so it's always (or almost always) making positive pressure.

i know this is kinda "out-there", and it would probably be a big pain in the ass and a lot of money to make work, but what are your opinions on this?hello, i'm doing a MST research project, and i chose to do something with cars. pretty much, i had to think up of an idea, and it doesn't have to be financially feasible and i don't have to build it.

I thought of that too, but then I realized the tank would have to be huge to hold enough air.

and on top of that you'd have to power a compressor to actually make the charge worthwile.

And on top of that 75% of the energy that actually spools the turbo comes from exhaust heat, so no, it wouldn't work.

haha, alright, it was worth a try. thanks for the replies though

what about injecting something like nitrous into the exhaust stream after the exhausting manifold and finding a way to combust it, and maybe have a small tank just for a little help? so, it would be pretty hot, and it would kinda mimic (sp?) what happens in an engine.

Nitrous would be a waste of time. You could do a lil something like what anti-lag does, dump fuel right into the header which combusts and helps spool the turbo. I suppose you could also use something like propane if you wanted to.
