home made supercharger project!!

[tim_blair]

for those who remember, bout 6 months ago i was posting about my homemade paxton style supercharger

well its very nearly ready to go into car car

the problem i had was the powersteering pulley (blacktop 4age)
was in the way of where the sc pulley is going

origonaly i was going to use an electric pwrstrn pump from an mr2
but i got bord and anoied with trying to set that up with motor control devices etc

so i made a bracket that relocates my pwrstrn pump to where the ac pump sits and hey presto i have the room for the sc

now all it needs is 2 mounts fab'd to mount the sc to the engine an oil drain, an oil feed and a belt

so for those of u who are interested on how it all goes please hang tight

Look forward to seeing it in motion. This should probably go in the projects section.

when you say home made supercharger, do you mean you've taken a compressor and centre section from a turbo and attached a pulley where the turbine used to be? Or have you done something more awesome, like attached a pulley where the motor goes on a hair dryer?

[xsspeed]

I think from memory its the former, effectively a procharger type setup

Pics are on this page, of 1st model, crampy's post 1/2 way down or so

Yeah, I'm looking forward to this project.

I'm keen to see what sort of results come of it.

[Malcolm]

intruiging - can't say I understand why you would do it, but good on you for doing it anyway

[tim_blair]

im doing it coz its unique not many ppl have a supercharged blacktop, i made the sc myself and my cars beging for sum boost fusion

so i spent all day 2day (goodfriday) mounting the sc
my god how long does it take to make 2 simple brackets (9am to 7pm)
now im home ive had alot of beers to take my back pain away

i have taken a bunch of pics and will put them up soon well maybe ill ask crampy to put them up for me coz hes the man and did it for me last time thanks crampy.

so ill hopefully have an oil drain made up soon, then all itl be is the oil feed and belt

lets hope it doesnt spin itself into oblivion

ps. if any one would like a more indepth talk on how ive done all this just ask

the problem i see is you wont spin the turbo to a speed where you'd make good psi. where as the procharger and the uk made charger of the same configuration have a gearbox arrangement to get the turbo up to speed. if its just direct drive from pulley to pulley, you'd have to have quite a big ratio to spin it to get most turbo's to optimum islands. 100,000 rpm's for most low inertia turbos and up to 200,000 for very high end turbo's. something silly like dinner plate to tea cup sized pulley's

whats your thoughts about this? and how will you over come this.

From memory he had a planetary gearset for said ratio.

Read the other forum, he is using a planetary gearbox from a starter motor and pulleys to get 1:15 ratio.
I think the gearset is going to fly apart seeing as its designed for around 5,000 rpm not 100,000.

it's still cool though. would have thought that since its running roller bearings and is no longer attached to the hot side of turbo you wouldn't need oil circulating. just some fancy oil in gearbox - shockproof ?

[tim_blair]

yea as said above im using a gearbox from a startermotor to get a 1:15 ratio so itl be spinning well fast enough

im just worried that when i rev it up itl chew itself to pieces but hey if that happens il just spend another few hundred hours and make a better one

[tim_blair]

it was just easier to make it with an oil circulation system running through it rather than sum fancy self lubericating system

Feel free to send me the pics again dude. I'll host them for you.

good work,
very interesting thats for sure, definatly keen to see what sort of results you have wether they be good or bad
