was wonderin if thiswill work on my sbc. it the throttle body has thrown me for a loop and cant quite tell if i can use it or not

 

what did it come off of, what kind of supercharger is it? looks like there is no base, so you'd need a base for it too. looks like the TB is for multi point injection. So, if you have TBI you need to convert. Anything can work, its just a matter of how well, and how much work you're willing to do

 

dunno what it came off of its a roots blower froma guy on ebay. he dont know either. i know it looks like multi port but idk. if you check out other pics of it, seems like you mount it ontop of a basic 4 barrel manifold.

 

to me it looks like the ones that were on super coupes or the GM supercharged 3800's. those are going to require a lot of modification to work, along with not producing enough boost to make it worthwhile.

 

i was wondering about that but i guess i will have to look into it some more. your right about the fab work. i just cant find my right application anywhere for a decent price and its driving me nuts.

 

you could probably get a carb roots blower and use a carb to TBI adapter, but how much power do you want to make? do you have a roller block? what heads are you using? do you have smog inspection? i know its a lot of questions but i'm just trying to give you all the help i can

 

im confused? carb roots blower and use a carb to tbi adapter? ok i forgot to mention that im doing a carb swap shortly, holly 650 dp mech sec. on top of a performer. not lookin to make crazy horsies. i will hopefully be buyin a set of ported 305 heads i dont remember the casting..the one grade under the 416's i beleive. NO SMOG INSPECTION!

 

ok, well, i was just going by your sig, if you just want to do a roots style blower then you could probably just do like a weiand 144 or something like that, and just throw the 650 on top. a roots style blower uses a special intake, it wont just bolt to the top of that performer.

 

yeah but i was really hopin to find a used system in fair condition for somewhat cheap but everything is like a grand. like i said if you look at the other pics, the mounting plate on the blower looks EXACTLY like a mounting plate for a 4 barrel carb.

 

did a few searches on this and im pretty sure this is not IS NOT a supercharger from a bonneville

 

ttt

 

anybody got any idea

 

ok i give up screw it

 

No way that would work unless you made a adapter plate to mount that supercharger onto a standard 4bbl intake manifold and hope to god that the blower pulley will line up with your other engine pullies. That would be the hardest part to do is get everything lined up and then you could drill each runner for injectors.

 

ok adapter plate...not a problem at all..alignment..not a problem either. runners? what runners?

 

bump

 

well,if you gonna mount that onto a standard 4bbl intake,there must be a way to fuel it and a carb isn't gonna fit anywhere on that. You must drill each runner to accept a individual injector.... unless you buy what I did. A magnacharger 122cid blower for Gen I SBC's. Proboboly just as cost effective as buying that,than spending a bunch of money to make a smaller supercharger work.

Just my $.02

 

isn't it hard on those types of blowers to run fuel through them?

 

I was curious what it was from as well for awhile. But, when he brought up what looked like a 4 barrel mounting hole ..... Thunderbird SC .... what your looking at is a thunderbird SC blower turned upside down. here one that shows the bottom view notice they look the same.http://cgi.ebay.com/ebaymotors/NOS-F...spagenameZWDVW

 

idea has been dropped

 

idea might not be dropped if i can get some support. TAKE A GOOD LOOK PEOPLE....that giant tube hanging off the back of it is a throttle body...why are you talking about runners...the only hard part would be getting fuel to flow through that throttle body...and im sure within the next couple of minutes i will find some time a fuel controller somewhere....please post opinions.

 

running fuel through that supercharger will damage it

 

On certian superchargers YES,in this case you can't just spare fuel into the TB and call it good. That throttle blade can't be open all the time for fuel to be sprayed in there either. Would be cool,but not gonna happen.

Your fuel would have to be delievered undernieth the blower like that blower was originally intended. Those blowers have injectors installed in the lower intake.

 

this is what fuel through one of them will do.eaton sc's are roots type and do have teflon on the rotors (do not send fuel through them).if it came off a GM 3800 it is an m90 which is the one you want. if you don't know, on the sides, does it seem round or do the sides of the casing sort of square off? if it's more square its an m90. Guess the teflon makes the rotors seal and when thats gone there goes boost ... You will have to use port injection to use that supercharger. .... I'de say abort mission unless you can adapt port injection.

 

im off the charts on this one..not understanding what the purpose of having a throttle body is if the fuel injected after the throttle body..what is the throttle body doing? controlling air?

 

ok ok so i see that supercharger is upside down..but now, i never said anything about running fuel through that setup, i was just askin if it will work at all..and the answer is YES. the only thing i would really have to do is custom mount it, either tap TWO injectors into the top of my manifold, or custom make an injector plate to mount underneith.

 

I forsee a LO-3 ... running lean and not sounding mean ... then comes the ominous knock as a rod shoots through the block ... then the owner in dismay relists his blower on ebay ........

 

Just about any engine in a late 80's to present day uses a throttle body that doens't have fuel go through it. They are all MPFI.

Example would be any L98 TPI motor or LT1 motor or the famous LS1 motors.

 

That is a M90 supercharger..... It is off a Holden Calais with a GM 3800 V6 (L67). Depending how old and miles, it will probably needs a new coupler. With those blowers the couplers go bad and it will sound like there is rocks toumbling inside the blower. If you brought your car to the dealer, they would replace the whole blower. The dealer doesn't know how to fix them. I've gotten about 9 blowers so far for about $50 each from dealers. I replace the coupler, port and polish and sell. How much did you get it for? The one you have is pretty hard to come by. The US version is alittle different (front wheel drive) yours is for a rear drive.

RTKJADAMS Sorry but that is a ford thunderbird supercharger.

 

U actually have it upside down in the pic. It is from a 89-95 Thunderbird SC. The opening (on th bottom in ur pic) is for the blower top. The throttle body runs on the left side of the car.

This being said, the blower runs stock 12PSI (M90) and can be bumped up alot more usuing different pullys. BUT the motor it came in was a 232ci 3.8L V6. I use tohave a 90tbird, someone has done it on here......5.7 I beleive.

I will search for it.

there ya go...it can be done but go with something bigger like a eaton M112 from a lightning etc.

so j this was your setup?

 

holy Shitt Jay! why didnt anyone show me this before..even worse..why didnt i think of this? if anyone has tried to do this or has done it compeletly or knows how to do it i have some serious fabrication questions so let me know

 

sorry half of my post got cut off...it wasnt my setup I ment to put someone on here has done it.
Jay

 

I didnt' see any posts on ET's/mph gains with that set-up... Did he make it to a track to show the gains before and after? Would be nice to see if the effort was truely worth it.

 

it's been done before. It's most likely a thunderbird SC supercharger. It's a little too small for a V8 about 5.0 liters, but it can be used with another one.

check the boards for Saturn5 's project. Malibu with 2 superchargers...it lived and ran, but i think he is working on other things now. Either check this board or the diy-prom section.

 

will do. i also followed that thread to another link about a guy slappin a blower intake on a 350, custom fabbing his own adapter plate to for the m90 and topping it off with a carb. "word on the street" is that those blowers arent made to accept blow through in meaning: the bearings? arent capable of getting gas on them or they go out..not sure but this is what i heard..on the upside of this is that a company makes bearings for them that will be ok to run with gas. ebay m90-100 bucks-adapter plate-40 bucks-intake-200 bucks- satisfaction of knowing I built something that worked for once-priceless. according to him he pushed like 5 psi with a different pulley.

 

here is a Holden, After looking closer I think your right it's from a Supercoupe

 

the holden looks close but I see quite a few differences to say it's not a holden .... it's definately from a T-Bird
