Twin SC progress

So I got my plates finally, but have been swamped with school, work, family and life. Today I had some free time so I got busy.
Here are the plates on my mock-up engine in the incredibly messy garage
They started as cardboard templates then 1/4" plywood transferred into AutoCAD for more accurate modeling. Apparently my measurements were slightly off as most of the holes had to be slotted about .020". I also found that the accessory bolt holes on my alum heads were not the same as my L98 irons. The ones closest to the intake are off by nearly 1/2"! An issue to address when I upgrade I suppose.
Today I made a tray for the drivers side blower. A drill press and a vice would have made this job cake. Oh well, I made due anyways
This is how it fits and attaches with 3 large bolts using the factory holes cast into the blower case. That is not its final install location, it is simply propped up on the valve cover to give a rough visual on where its going
I had been thinking about the entire setup as well. As the design stands it uses a single belt to power both blowers, the WP(soon to be electric) and the alt. The WP is securely affixed and will never flex. The alt on the otherhand is only secured to the pass motor plate and will flex with it (ever so slightly). This could lead to minor slippage and possible belt loss.
Old
My new idea is to run two belts. Crank, WP, Alt and a second on the Crank and blowers. This should remove all possible chances of the alt mounting screwing up the blower operation. The downside would be additional complexity
I should have more later

More today before it got too cold
I made the other side's tray (not pictured) and the end brace for the drivers side. The remainder of the day was measuring and fitment
In-car fit
Pretty damn good
This is why I had to give up power brakes
Lots of room
Very tight
Lots of room for the "hat"
I did run into an issue with the hood. As it stands I cannot close it fully. The blower is contacting near the front by about 1/4"
A bit of luck I designed the front plates pretty tall in case I ever went with larger rockers
I have 1.125" of clearance between the tray and valve cover. Dropping the drop of the plates down 7/8"-1" should give ample clearance then without compromising "hat" real estate
Thoughts? Opinions so far?

looks pretty cool. are you going to mill the hole for the induction before you get too far in?
projected hp?
also, how much do you have in the setup so far? -- '91 Firebird 305 & 5 speed. Currently on the injured list.

Plamsa cut it once I make the hat
Plan for 650ish at the crank, although Id be happy if the damned thing ran at all
Blower #1 cost $90some
Blower #2 cost $120some rebuild should be around $85 each
Plates and angle iron cost $50
This project doesnt have a budget, just whatever I can piece together

I chose steel because I cannot weld alum currently and alum is quite a bit more expensive
Different and better? Absolutely
This is more of a challenge than a perfect power adder, and it also have a great deal of room for improvement. I can upgrade one or both sides to M112's with any major design changes

I did a MASSPROP on the model and the weight difference between 1/4" steel and 1/2" alum was 8 lbs
Not as heavy as one would think
Anyways the plates and blowers weigh less than the factory accessories

I just had a great idea..... Instead of a remote mounted turbo..... A remote mounted supercharger. it could be driven from the driveshaft!!!

is this setup going to be intercooled?
if so, dont you have to use a water setup? arent those usually put under the supercharger?
i'm a dope, i know. i've been hanging around these GTP guys too long, but thats how they do it.
they run an electric pump, a chiracco radiator up front and then this 3" thick aluminum spacer under the blower that has a "heater core" in it and they pump coolant through it the system.
i was told the "air to air" intercoolers were for turbo only. -- 1998 Dodge Neon Sport - 2.0 DOHC - MTx - 30.3 MPG City - Daily Driver

Most roots guys cannot/dont use FMIC because of a packaging issue. They usually use an air to water intercooler under the blower like you described
These units are remote so I dont have to sandwich the IC under the blower outlet, I simply move it down the plumbing to a better location which will be in front of the radiator
Turbo only is nonsense, centri SC guys also use single or dual ATA IC's for simplicity
Make sense?
Plan is to use one of these

Initial routing plan
Talking to luken4trbl made me think about rerouting the outlet to a more direct path between the rad and headlight
Also depending on the IC I pick, the outlet direction will change

Since Ive been cooped up here with mono I decided to update the old CAD model to my current progress
My metalwork hasnt changed, this is just how the design sits now
I had to rotate the passenger blower to the angle of the valve covers. The engine in 3rd gens is not centered in the car, leaning about 3/4" to the pass side. This cuts down on my already tight space. The rotation clears the blower case from hood contact. Hood contact on this side is not an issue
This diagram shows where the pulley would be had it not been rotated, and where the pulleys would be if the drivers side was turned as well. The pass side only dropped 1/4" but the drivers side drops about 1 1/4". The idler pulley would have to be moved, but thats no problem. Id only rotate the drivers side if the hood clearance is still an issue
Early models had braces ran to a center intake bolt. Now that the brackets are nowhere near the intake, I had to redesign them. A simple bracket welded to the header flange makes sense. I drew in a flange to squeeze between the primary tubes, I doubt it will actually fit. Thinking about the stresses applied to the bracket it will primarily see tension, so this flange is not necessary
This shows the pass side where the hat will go. Unlike the original design, this side will require an off center hat that must work within the braces holding the blower bracket up. I predict a good bit of difficulty in this area
I just liked this image

I like the custom fab and CAD pics, but that alternator area looks a little bothering to me how the belt doesn't really wrap around the pulley much. -- 1982 Z28, 383, D-1SC intercooled @ 15psi, trick flow heads, solid roller cam, 3.73's, th400,

Pics of the mock-up
Drivers valve cover clearance, approx 1/4"
Pass, yes its resting on the bolt, but the clearance is about the same
Underside of the drivers. Plenty of room for the hat and flange from the headers
A little tighter clearance on the pass side. You can see why an offset hat is needed
Does the alt really need much wrap?

It might be completely fine that way, but for extra insurance I think I'd like another idler near the alternator to wrap more belt on it. Another thought too, how long of a belt is that going to take? Might get some belt to make sure it will use a belt that is more of a normally stocked size. -- 1982 Z28, 383, D-1SC intercooled @ 15psi, trick flow heads, solid roller cam, 3.73's, th400,

After alot of searching I found this gem
http://www.goodyearep.com/productsdetail.aspx?id=3128
With my current setup I use the factory belt from a Buick Park Avenue 3.8
Adding an extra idler for the alt would add 6-8" putting me in the 108-110 range which is also supported
Im still toying the two belt idea as well, Im just not sure where to get a LS1 style crank pulley made for a GEN I

I finished the brackets and have been working on mounting the tensioner, alt and idlers. Trying to dig up a camera so deal with CAD for now
I was thinking alot about the belt routing and how things could go wrong, and I came up with alternatives
Left side uses a single serp belt, top is stock 8" crank pulley. Bottom uses underdrive pulley which is counter productive for SC engines, but should drop the pressure for initial startup and base tuning
The right side uses two belts. A serp for the blowers, crank, WP; and a V-belt for the alt to Crank or alt to WP. Either way should pose little difficulty. The hard part is finding a crank or WP pulley with a 6-8 rib serp and a single V groove. Several older chevy trucks have a 5 rib with a V, but I highly doubt 5 ribs will be enough contact area to spin the blowers. 6 rib likely wont be much better, but its what Ive got now and should put me in the right direction without dropping alot of money into custom 8 rib pulleys that may or may not workout

I like the left two, way to get more belt on the alt. If you needed to use a belt just for the alt. I'd move it forward and pile on another pulley on the crank to drive it. I did this for my belt drive fuel pump. Used the 3 balancer bolts to hold a plate that I welded an exhaust piece to to help center it on the big center washer as well as possition the 2" pulley in front of the regular pulley. -- 1982 Z28, 383, D-1SC intercooled @ 15psi, trick flow heads, solid roller cam, 3.73's, th400,

I rebuilt both blower snouts today using an ebay kit
Read:
http://www.rollingperformance.com/snoutrebuild.htm
It wasnt that hard really, just time consuming and problems arising
#1 Im a huge cheapass and will not be paying $150 for a pulley remover
http://www.pulleyboys.com/fordsvtpt.html
So I fired up the welder and made one with a bolt, a nut, and a few short bits of angle iron. One advantage of mine is I ground the bolt to a point so it wont try to 'walk' off the tip of the main shaft and damage the threads. It just isnt pretty like the expensive one
#2 The snout bolts are supposed to be torqued to 65inch pounds. I had to use a breaker bar to get them loose and they're only 10mm
#3 The second job was to replace the snout seal. I figured it would be easier to pull the old one out if the main shaft was removed. According to the article, a few taps of a rubber mallet will knock it out. It didnt. My 4lb mini sledge couldnt knock it out either, so the seal was done with the shaft still installed
#4 Im not sure what epoxy the factory used to secure the rotor pack section of the case to the main case but it wouldnt come out. I could have driven a screwdriver in between, but risk of damage would have been high and I wasnt risking it
#5 Old SC oil stinks. Alot. New SC oil isnt much better
#6 The latex gloves provided in the kit did little more than disintegrate and get in the way, so you will smell like old SC oil anyways
#7 Both of my drain plugs were rounded. While new ones are available, that didnt help me removing the old ones. Stock, they take a 3/16" allen key. If you take a 5mm and hammer it in there, it will come out with no fuss. Why the factory didnt put a hex head just above the plug surface I dont know. There is nothing (on the T-birds) remotely close to it

Its about 15 lbs, cheap and plentiful in nearly any JY. Nearly the same length as a Fbody linkage, and the fiero steering shaft is perfect length and will fit the Fbody column end fine. Additionally it is full manual, so halfass conversions are a thing of the past

I put the 0411 harness on it to test final fitment. The stock behind the fender route was too long for me so I ran it thru the heater core block off plate. That cut about 4 feet of wiring out and i wont have to remove the fender any more to get the HUGE 0411 PCM connectors thru
It fits alot better than the TPI harness and has a minimalist appearance
As it sits i cannot correctly set the timing with the vortec dist. Rotating it to true TDC pushes the #3 plug wire into the FPR and prevents the last 5* or so of rotation I need. At most the vortec dist can handle being out 2-3*
I talked with my tuner and he suggested i scrap the SD 0411 idea and run a MAF. Now I get to find another 5 wire sensor and pigtail and mod the harness for the 5th time
I grabbed a 4.3 waterneck because it was steel and i wanted to fashion my own design to snake around the belt better than the stock TPI strait neck. It turns out that the stock 4.3 neck has all the bends and lengths in the right spots so i wont have to mod anything. The downside of running the water line thru the belt is I have to drain the coolant for each belt change, and from reading prev swaps, belt changes are regular
While not related in anyway, this should satisfy your need for pics

I got a little happy with my saw-zall
Actually Im changing the rake of the radiator and adding the FMIC makes packaging difficult to say the least. Not like I need any of that metal for the strip
If they give me trouble Ill just weld it back on and figure out a new duct routing. No biggie

Ive become an expert as LSx wiring too apparently as 3 members PM me regularly with issues to remedy
Most would be fixed if they didnt reuse the goddamn 4th gen harness in its entirety
