HI dharvin,I am looking for the same type of smoke machine.You got my attention when you said it was for a model car.I can only think it is for the same thing.I went to a local hobby shop and bought a smoke device out of a 1/12 scale remote army tank that they had in the back room.It runs of of 7.4 volt batt.pack and will do a pretty good job.But I dont like the noise it makes,and I would like to produce more smoke.If you go to ebay and punch in Wizard Stick you will get a close design (but still to large) for what we need.I bought one just to have it for my project it smokes pretty good but you have to keep pumping it.This is an on going project of mine that I have been working on for some time.If you would like please keep in touch,and we can compare notes and ideas.
Thank you,Matt
