Talk about cheaply turbo-ing a 5sfe, BADDDDDDD Options

Nice right up CelicaST. With adtvances in electronics, it's very possible. The problems I see is they are marketed as cheap alternitives. To make one work correctly it would have to have a fair amount of RD and money invested. There's so much info out there on superchargers and turboes, that it makes them as easier alternative for most. If the right guy felt like doing a e-turbo, I see no reason it couldn't work just as well. I like to compare it to carbs vs fuel injection. When FI came out, the car guys would switch it to carb right away. Some still do this. It's easier and everyone knew more about working with carbs. Besides that, there weren't many performance upgrades redily avalible for FI. But the problem with that comparision, is that race cars when to FI way before they went to street. And it was known that FI would be better for race cars. No race teams that I know of use e-turboes. This might be because there just hasn't been the desire to look into them yet. I think we'll switch to electric cars before e-turboes are popular. But the fact stands, it is very possible to make one work. Even the ones they sell will do something, just help to equilize pressure. That won't produce much of a gain, but you can't deny it's doing something.

I think this topic will actually stay open awhile. Everyone so far is presenting reasonable arguements and no one has jumped in to simply bash on anyone.

im going to say it impossible to even get ANY 12v motor to supply enough air to any combustion motor. no way no how. and lets pretend it does work lol. you still need to upgrade the fuel system and the timing and the sensors. its just not practical. and its only a fan. it can push air yes but it cant Pressurize a chamber.

now maybe a 10hp shop vac fan could do something

im sorry, but you sound ignorant on this. what do you call a turbo compressor? its a fan, a highly specialized fan. its a radial fan as opposed to an axial fan your probably talking about, but still. now your right, a 12v motor isnt going to be powerful enough without very high amperage (but that will cause overheating issues) to supply the air needed, but thats why theres AC inverters and transformers by the way, "it can push air but it cant pressurize a chamber." i would like you to read that again to yourself. if you cut a hole in a box, put a room fan in the hole and turn it on, tada a pressurized chamber, although wouldnt be that much over atmosperic with a low power room fan. guys this is very practical, it just needs to be done correctly.

also, if i do get the chance to build this as a senior project, i would most likely use the compressor housing off of a turbo.

Or with a 12v electrical fan either. And pressurizing the positive boost system is what is needed. While I remain extremely sceptical (understatement) I say go for it and post your results.

well im only a freshman, and im not saying theres going to be some issues, but thats what engineering is about . main issue is power, highest amperage alternator ive seen is 300amp. at 12v output thats just around 4.8hp. im not sure whether or not that would be sufficient enough to run the compressor at desired boost. other ideas ive had would be a retro-fit system to install on a car to capture energy lost while braking. well see, its still a ways off. probably end up doing the sae race car or hpv.
