Thought I'd post a couple pics of the airbox. cheers, Bob

 

side...

 

simply amazing...

is she done?

 

Thanks. Yes for the most part. Going to do a teardown and clean everything up, grind the welds and repaint. Now just need to make a template for the hood.

 

Thats bad ***, where can you buy those kits?

 

That looks so flarkn good,....

If you showed that to somebody that wasn't into cars you could say it's factory and they'd believe you,

keep up the good work

Cheers

 

OOHHHH BABY! ....Looks great man! Torque monster that should live up to its rather large rockets name....

It don't look like no kit to me....looks like craftsmanship....beautiful work

 

Very nice. Hell of a good job. Love that hood. Where did you get those inserts to put in there? Thanks.

Brad...

 

Thanks.

The inserts are from 87-88 Turbo T-Bird hood. Real nice scoops, have a nice stamped steel mounting bracket and 4 mounting studs. I have some inner sheet bracing to trim and then bend up a "upper" box to seal against the filter.

Oh.. for those that asked. Its not a kit. all home-shop built. BW

 

Wow SATURN5, that's just amazing.. I love it.. What you're doing now was my initial plan for the Z28, but I fell into some good cheap turbos, and well, you know the rest of the story on that...

Nice job, keep us up to date!

Cheers!

 

Oh yea, I wanted to ask you if you think it will be ok having no throttle bodies in front of the inlet on the 2 superchargers? This was something I was wondering when I first wanted to do it to my car... (carburated tho)

I guess I can't see any reason why not... Turbos run the same way, so I would assume that it would be ok...

Cheers,

 

Well I'm running both blowers ahead of the TB and am using a 1gen DSM blow off valve too bleed off extra air at idle. The $58 code is speed density based, no need to recycle the bleed off. BW

 

you should build that and sell it as a kit for the rest of us

 

ok wait maybe im blind but where does the air acctually enter the engine at ?? im confused

 

That engine bay just gets better and better.

SuperTrans Man,
the air comes in thru the filter box atop the engine. this feeds the superchargers which force the air forward thru the intercoolers and then up into the engine.

 

Hey Bob,

thats one heck of a nice box you got there its comeing together very clean.

BW

 

That it definitly a job well done!!!

 

Looks amazing...

 

damn, that thing's gonna be hella fun on the street

 

LMFAO!

 

I kept trying to figure out where your air filters where, now I know. That is a sweet set up! :hail:

 

looks like you went rubber and plastic from the airbox D/side and metal pipe from the airbox on the pass, is this staying this way?

 

awww c'mon go easy on him... i'm sure you were a noob at one point in time we all learn something new everyday..

lottaballs - it isn't a kit, everything he did is custom... those are the kind of superchargers that come stock on supercharged thunderbirds, bonnevilles, etc...

 

Hey, **** off ok, its quite obvious that the tubing and such is custom but I thought maybe the mount for it could possibly be purchased. I'm not an idiot.

 

Actually its metal and rubber on both sides, in the pic the drivers side was a painted flat black . I made an adapter to convert the Eaton input opening to 3 inch round. The rubber elbows are the MAF ends from a 88 TPI T/A intake hose. I cut off the TB side. Used 3 inch steel bends across the plenum. Then opened to fit the box.

cheers, BW

 

Hey if anyones interested i've got one of these exact same blowers for sale, good condition.

I'd easy let it go for $250 or best offer.

Thanks

 

you should keep it as a spare in case one of them beauties fails, BTW what is the normal max RPM unit operation on a 3.8? what could it be on yours, I know you checked into this Im just wondering about how you sized your pulleys and figured it out.

 

I know that you didn’t ask me, but eaton doesn’t provide any information on them past 12,000rpm, and the stock applications top out at 10,000-12,000. On my brother’s car with a modified M90 case we’re spinning it right up to around 18,000rpm (2.8:1 pulley ratio, 6400rpm shift point, 6500rpm redline). I think that it will take 20,000, but my brother isn’t willing to try it.

 

Not giving up on the LT1 are you???

 

nope ...

Last night I bought a M112.

Hehe

I've got a spare intake i've cut in half and having decked down. From ther i'm going to weld a 3/8's 6061 plate to the top of it and mount the blower.

I'm going to run a throttle body on the back of the blower just like a lightning or cobra.

 

Oh.... hehe

 

yeah i just didn't think a single Eaton M90 was enought for a car that already runs 12.50's

The M112 is supernice, I've heard they are capable of 20psi on lightnings. I really like the internal bypass valve and the demensions are a little better for my application than a M90

I'll post some pictures hopefully.

 

hmmmm twin M112's that would be kinda cooooolll....

 

noooooooooooooooo...

just one, two would be a little much!

Its going to be mounted like any other Eaton you see on factory cars.

I've got a intake cut and decked. I've got a spare set of fuel rails to butcher. a spare throttle body with an elbow that bolts to the back of the blower, and spare injectors.

I'm still seeking a cheap FMU (speed density 93 LT1, no 749 swap capabilites because of the all mighty opti spark)

The only thing i've got to do now is have the injector bosses redrilled in my stock manifold to clearance the blower. I need the injectorbosses straight 90 degrees verticle.

 

a LT1 will take a distributor

 

not when its still in a 4th gen,

it might but every car i've seen has had to cut into the car to clearance it,

either that or pull the motor out if you want to take the distributor out

 

oh, ok

 

Well, my brother's 4 door ford will be running 10's with it this year. 1.5-2seconds better in the 1/4 is a long way to go...



I've been looking at some custom rotor mods. If I can convince him to do it I think I could get it to move the same air at about 12000-13000rpm as it is now at 18000, which in theory should allow him to tickel the low 10's turning it at the speed he's turning it now.

Do you have the M112 in your hands? I'd like to see side by side pictures... as far as I can tell from the eaton drawings of them the case should be substantially larger, but with a shorter snout. I'd still rather cut up his passenger side inner fender and strut tower and wedge one of those in.

 

Ooohhhhhh Yeaaaaaa!

Spinning at 12K you should have enough airflow for about 1000hp

 

Little update on the Bu.

Couldn't make the filter box work the way I wanted, so I have switched to K/N cones perched over the inner wheel houses. Adjusted the DS eaton forward an 1/8th to fix an alignment problem and welding a bead on the tubes (for hose retention).

Getting the brakes and chassis finished and checked.

Most of all waiting for warmer weather..

BW


Oh... been kicking of going AWD next.

 

Crossfire,

Find eatons website and click on information about the M112,

Its the same width as a M90, shorter (up and down) but a touch longer.

The bad thing is the position of the intake to the blower

The m112 has an internal bypas valve too
