alright, i was searching the net for ideas about how to supercharge my H23 BB4 and i stumbled upon this thread on preludepower.com. pretty cool build from a prototype standpoint.

heres the thread
http://www.preludepower.com/forums/s...=303997&page=3

now i got a few questions lol.

since the thread shows that its possible, does anyone know where i could get my grubby hands on one?

also, looking at the "WTF?" placement of his air filter, im wondering if this S/C for a scion TC would work better?
http://cgi.ebay.com/ebaymotors/NEW-T...Q5fAccessories
seems like it would sit right about where the battery normally sits and make a better fit as far as ducting is concerned.

what kind of fuel management/boost control do you think would be needed?

if im gonna do something crazy like this i wanna get as many of the problems sorted out as possible before i make any investments of time/money. please post comments/ideas freely, im lookin for as much info as possible. some input from experienced fabricators would be appreciated as well, since im anticipating lots of custom bracketing/ducting/wiring with this kind of build. im also gonna set up a profile on that site and try to contact th OP and ask him some Q's as well.

yes i know this is probably more involved and messed up than a turbo system, but i want that S/C whine and the low end grunt. furthermore, i like the idea of being the only guy at a meet with a S/C'd H23 BB4. sooooo many turbo ludes out there, i want something people will look at and go "wow thats cool".

anyway, ideas/comments welcome so post away.

 

that looks like a very shitty setup

 

like i said, its never been done before. so for a PROTOTYPE its not bad. yes in this form it pretty Effin rough, but it can be done.

not the kind of posts i was lookin for iwantkill LOL

 

First off , its your car and have fun building this. how much boost do you wanna make? is it gonna be intercooled? the smallest pulley available on 05 S/C for the Tc is a 14 lbs pulley. if you get an 05-06 make sure to replace the bearings, and the shaft. Im really knowledgeble on the Tc 05 S/C cuz I have one on my 05 Scion Tc lol. Contact me if you want more info on the charger. my AIM sn is Gamer582000.

 

im lookin for mild boost, 5-10PSI. i dont want to have to buy forged internals.
as for it being intercooled, im not sure... thats why i posted the thread.

woud you suggest an intercooler for that TC S/C? or any S/C for that matter?

what kind of boost does the TC one make?

do you think it would be possible to hybridize the two? i like the driveshaft idea on the TC model, but im worried about it producing too much boost and totalling my motor.

i like the sound of the roots-type S/C, but havent heard anything with one of the centrifugal (sp?) types installed, do they sound more like a turbo?

thanks

 

well for the sound you can search that on youtube. Our Tc's have 9.6:1 CR and the S/C is stock at 7 PSI@ redline which is 6200 RPM. I mean mine doesnt have an intercooler on it, but its backwards compared to a honda setup so its very inconvienent to have one setup because of the piping. The driveshaft doesnt do anything to the boost, it just allows the SC to be mounted farther away.

 

well the s/c in that thread is the older mr-2 s/c
they are actually clutch driven like an a/c compressor
so u actually could wire it up to a switch....also
i think some older toyota previa mini vans have this as well

it is basicially,,,just getting it mounted up correctlly and some welding
cutting,,,,also tunning and bigger injectors will be needed

 

Yikes, that is a rigged up job. I suppose it works fine, but it's so messy and unrefined (electrical tape wire connections?). He has no cooler like everyone said and I didn't see anything about tuning. That is going to make some very high IATs without a cooler of some sort and kill power...not to mention he has no tuning with that setup. It's not going to last very long especially with those $28 Advance Auto bearings.

My comment to you is: If you have the time and ability, go for it! Anything can be done, but I wouldn't do it like this guy did.

 

LOL totally. i think he did a hacksaw job personally, but the theory is sound. someone needs to take the idea and run with it, if you know what i mean. and honestly if he would take some pride in the appearance his engine bay, it would probably LOOK alot better. LOL

honestly this is something im gonna do down the road. money is tight and i got more important things to focus on, like getting everything squared away so i can go back to school. but its still on the to-do list, and what better way to spend down time than researching cool things to do to your car.

im just trying to get all my research done so i know what kind of job im looking at, what extra equipment i'll need to buy, ect.

so the list of **** i'll need (so far):
big pile o' cash :-D
intercooler
larger injectors
a Tune

anything else? besides common sense...

 

Well you will need bigger injectors, and a tune off of a piggy back or something. Heres some more info on the S/C for you: http://www.scionlife.com/forums/viewtopic.php?t=190618 you wont need all the info there, but it might be good reference material.

 

Stuff like this breeds innovation.

 

after further research, i have found out that i dont want to use the S/C off the scion because its a centrifugal S/C system. essentially, centrifugal superchargers work the same as a turbo system in that they only produce usable boost at higher RMP. and on top of that they actually rob you of HP at lower rmp ranges.

i wanna build an autoX/track toy that has usable power and torque at the 2500-5000rpm range. that scion S/C doesnt start producing boost until the engine is above 3500-4000rpm. looks like im gonna have to work on some way of mating a roots-type S/C to a driveshaft assembly and mount it where the 4th gen battery sits. because is DONT want my sh*t lookin like the prototype. /shiver

so, the updated list of sh*t i gotta find
SC12 supercharger or something similar
air/air or air/water intercooler
larger injectors
aftermarket fuel managemnt system (hondata, ect)
tune up
3" piping

anyway, keep up the feedback. this is helping alot.

 

just wondering what happened?

I have been trying to research this myself let me know if I am wrong about anything.

d16s b16s and b18s spin counter clockwise
the SC12 is meant to only spin clock ways and not both like the SC14 can is this true?
