Supercharger fabrication idea

Theoretically couldnt one take the lower intake manifold from a carburated 2.8 engine and fabricate a middle manifold that would allow one to use the supercharger from the 3800 series engines on iron headed 2.8 and 3.1s? ive been researching different turbos and supercharges and really want to try something new and this seems pretty possible, Im just wondering if that supercharger has any collant ports through it for me to worry about fabricating coolant passages, if not even better, but i got time on my hands and and a lil money to waste, ive seen a supercharger out there for 2.8 s-10s but its only a 35% increase in power and for $1400 it doesnt seem worth it, think this set up would give me more power increase then that ? any critisism on my idea is welcome, thanks

no need to fab anything.
They make a blower/super charger kit for the 2.8s

guy 614street had a s10 with a super charged 2.8

has a thread somewhere, with details of the build, home made pop off valve..................................

If you bother to read that thread. in july he offered to build and sell the kits for $1650 us.

So parts must be somewhere.

if i remember correctly, 614streets knows somebody, somewhere that could build the blowers. but, no, they are not readily available (new).

that supercharger only adds about a 35% increase in power, 49 more hp is not worth the kit price in my opinion, taking the carburated lower intake and modifying it to accept any engine mounted supercharger would probaly add more power, im looking for at least a 50% increase, i think 70 hp would be worth it, exspecialy with headers and dual cat back exhaust, i think my best option is to get a belt mounted supercharger and modify that, if you look at some of the fiero supercharger set ups it makes doing it on a camaro look like playing with legos or k'nex, and going that route i can keep mpfi (i just need to change which map i use i believe)

You've got alot of learning about forced induction systems and electronic fuel injection to take care of before you even start talking about fabricating a supercharger.

1: The fageol 60v6 supercharger is not limited to nor gauranteed to create a 35% power increase. That is the advertised approximate power increase using the pulley included in the kit. Using a smaller pulley would yield higher intake pressures, resulting in a greater power increase.

2: You would need to change more than a map. Your MAP sensor would need to be replaced with a 2-bar unit to read up to 14.7 psi of positive intake pressure, your ecu's prom would need to be replaced with one set to work with positive intake pressures, your ecu wiring harness would need to be repinned according to the code used on the new chip, you would need larger fuel injectors, etc etc etc.

never talked about fabricating a supercharger, just modifying existing parts for a existing supercharger, my original idea was to use the lowest intake off a carbed 2.8 as a base, somebody pointed out that there was already a supercharger that used that base or was meant for a 2.8, i had already seen it and decided that i didnt want to use it, im a creative person an have a lil money to spend on this project, most of the supercharger systems ive been looking at have been carbed i didnt realize you needed bigger fuel injectors and a reprogrammed computer, thank you for that information, i know i have alot to learn still though thats why the picture in my head was very similar to that kit, but its more an amalgam between the fageol and a 3.8 eaton supercharger for ford/chevy 3.8s, i guess if i told you i was now planning to mount the supercharger as the top plenum with custom spacer/runners as a fabricated mating point and do a bunch of custom throttle body and electrical work to mate with my cars sytems that id be like crazy or something *smiles*, with what ive seen out there its doable, i just need to research more into these reprogrammed computers for supercharged camaros and what exactly gets changed

Since I have a 6/60 camaro, and a M90 on my other car, trust me. I have looked.

The snout on the m90 is very long, and it really wont allow the s/c to be centered on the runners like it Idealy should be.

Also, space on the rear of the m90 where the tb should be, will be exreamly close to the fire wall. I am not sure how the mufstangs and lightnings take care of this. But it would need a REALLY sharp turn either between the tb and s/c, or before the tb.

You will have to totally re-route the belt for the sc and make a few idler/tension pullys to keep propper grip of the pully.

It will clear the hood aslong as its mounted directly to the base. How much space is left I couldnt accurately figure out. However, if you plan to keep the multiport injection, you would have to come up with a totally new fuel design as stacking the s/c above the fuel rail will make it set out the hood though.

No easy way, but I'm not saying it cant be done.

Anything can be done, just not easily and not cheap, i think if i get the height and offset of the supercharger right and delete the a/c and have 2 idler tensioners i can use a stock W a/c belt to run it, just need a custom pulley to fit that belt size, the ford eaton m90 is set up different then a gm,its better suited to be modified imo, i just wish i could get my hands on the 2 in person instead of looking at all these damn pictures on ebay, there are things i need to see on them, currently im thinking of getting a ford eaton and putting on the gm long snout, custom runner section below supercharger, customer intake piping from the back to run the throttle body aside or atop the supercharger and since this will be above the hood add a custom k & filter like they use on the tpi tb, i dunno, its just my idea at the moment, itll look like its something out of mad max, and that i love

I have 1 carbed kit brand new in box left , I sold the other to a guy in tawain with a 3.4 in a fiero.

The kit makes 45% more power at just 5 lbs of boost and thats at mid range. With 10lbs of boost and a cam/header / etc etc work you will see well over 75% more hp.

I have one right now on ebay starting at just 900....

I also have pics of these kits on a camaro inside the instruction booklet , the instruction booklet alone is about 45 pages jam packed with any information you could imagine, and btw these arent bm/ weind like roots blowers , these are high effiecency roots blowers with no cast parts....


/* MOD EDIT: Ebay link removed. */


These blower kits are the real deal , I wont be selling any more so if you want the best supercharger kit avail for an iron headed v6 I would buy this now before you never see one again.....


I can put my s10 in second gear and tap the throttle and it will spin the whole truck around........

well i wantted to customize something myself and i had thought the kit only added 35% more power, but a 45% - 75% increase depending on other mods sounds pretty damn sweet for only 900 exspecial since its a bolt on kit, i guess i could make it TBI and have it custom in that way, So now i need a remanufactured engine, trans,and rear end then i get to add this bolt on supercharger, by january-febuary ill have a 15yo car with a 100% new drive train and almost v8 power, 245 rwhp and 315 rwt at 75% increase , but hey ill settle for 210rwhp and 270 rwt at a 50% increase

this may be out of topic now but should i switch to the 460le trans or whatever it was that replaced the 700r4?, or should i get a v6 7004r built to v8 specs, or would a brand new remaned 700r4 trans be able to handle the increase in power? what kinda torque converter....., damn i got alot of quuestions, lol

Have the 700r4 rebuilt with v8 guts (there almost the same), shift kit, boost valve, whatever that round thing is on the side, and custom torque converter.

They can be built to hold some power, but it takes some good parts, and someone who knows what there doing.

I wouldn't buy from autozone unless its a good name brand.
But I would probably buy new built over used local built.

Id go with the 460le or adapt a th, even a 200r.
I just don't like the 700r's, to many horror storie.
[except the buick turbo 700r's, hord them like gold]

But id go stick like 614.
Real men only need one hand to hang on

to have it rebuilt, any shop can do that. What I'm talking about is a custom build one thats stronger then OEM specs. You will have to find a shop that agrees to do what you ask, and will do it(rather then say they did, and didnt).

I wont buy anything mechanical from zone anymore, had to many parts go out pre-mature.

have the 700r4 rebuilt. find a reputable shop that can do a performance rebuild. shop around, they don't have to be really expensive. i recently found a guy who is only about an hour away from me who said he gets $550 to rebuild one and will warrenty hard parts, even knowing it will be raced. 4L60e is the same thing as the 700r4 except its electronic (hence the "e" on the end). 700s are good trannys and becoming more popular for street/strip cars and trucks. if you buy one from autozone or some place like that, it'll most likely be a stock setup inside, you will probably burn up the clutches with the soft shifts and all.

haha hey now autzone does have some of the better parts outtve most of the local parts stores(yeah im biased i work there haha) but i do agree i wouldnt buy a tranny from them, we dont offer much for what you are wanting to do. most are just stock rebuilds or slightly upgraded.

i agree with the going to a manual trans, youll gain so much more from that and about the worst problem you will have is burning a clutch. you can get a whole used setup for around 700 bucks through the sponser links at the top of the page, i got mine from hawks....and i havent looked back haha

I swear the pads on that car where really like 15yo and i know the rotors where, but no i dont think that the new ones will last that long, brake pads are a throw away part everybody knows that, i know i have odd ideas and i sometimes skip parts of an idea thatd make it more whole but im not retarded just not as educated and expierenced as id like, which is why i treasure these forums,advice. Im very happy with my purchase, i just have alot of work ahead of me to put this on my camaro and stay mpfi, Btw no clerance to stand injectors straight up, the injectors have to face in, following the lines of the V made by the cylinders, with the force of boost im not worried about this affecting much, if anything. From what ive read on the alternative port intakes and info from other intake projects ive seen online it wont matter.

i don't really know which way you're planning to go for sure but, personally, i would put the injectors before the s/c. much easier to do.

Yea thats true, but then its not mpfi, i mean itll be getting as much fuel if there added pre supercharger but will each cylinder be getting the same amounts? id rather add them at the angle i can, even if its the wrong direction, and hope the compression is enough to suck the fuel into the air with enough vaporization, thats all that matters right? i have decided to buy a remaned block instead of a new trans, ill drive save and slow till i can save for the trans.
