Roots blower how to

by V6sprout

So you want to install a roots blower from the thunderbuird Supercoupe on your mustang eh? Will it work? What all is needed? How hard is it? How well will my mustang block hold up? Read on.........

First of all WILL IT WORK?

YES but its not easy

Second what all is needed?

LOTS! Basically its easier and cheaper to buy the entire SC motor, but if you want to install it on your mustang block here is what you need.

-Roots blower
-SC blower top
-SC lower intake
-SC rear blower intake with SC TB
-Rear intake (from IC to lower intake)
-SC thermostat housing
-SC jackshaft pulley bracket
-SC PS pump bracket
-SC crank pulley
-SC water pump and pulley
-PS pump pulley (you can us your mustang pump)
-SC tensioner pulleys (all 3)
-if using the SC block/crank then use the 94-95 neutral balanced dampener with exeter gear, some dampeners off the F150 will work as well.
-if using the mustang block/crank then use you stock mustang dampener
-if using the SC block/crank then use the SC flywheel/flexplate
-if using the mustang block/crank then use the mustang flywheel/flexplate
-Mustang or SC starter will be fine, they are the same
-Mustang headers
-SC heads are better but Mustang heads would probably be fine (SC heads are supposedly a little stronger)
-SC injectors or eqivilent plus matching MAF
-89-93 SC came with 30# injectors and 55mm MAF
-94-95 came with 36# injectors and 70mm MAF
-all cooling hoses
-SC thorttle cable
-SC throttle cable bracket
-MUSTANG wiring harness
-wire to lengthen wiring harness connectors
-extra cooling hoses for custom work
-MUSTANG timing chain cover or 94-95 SC timing chain cover
-MUSTANG crank sensor
-MUSTANG or SC alt will work, MUSATNG better sicne it has the extra connect on it, but will work without it for the SC alt, need to change pulleys if using the Mustang Alt. I believe the Mustang alt is more powerful as well, not exactly sure.
-SC AC compressor
-custom AC lines
-custom air inlet needed
-SC intercooler should work, not sure how well the SC intercooler tubes will clear but they should
or use a custom IC setup like me [img]images/smiles/icon_smile.gif[/img]
-Mustang motor mounts
-SC valve covers
-Mustang DIS module, don't need the SC one.
-SC oil cooler (not needed but good to have)
-Mustng rad will work, but if using the SC IC then might be easier to us ethe SC rad its a little smaller though but works for the SC guys fine.
-Major tuning
-SC coil pack bracket (mustang coil pack should work but I have the SC coil pack as well)

Now, how hard it is?

Well that all depends, if you have the complete motor it will be a lot easier, basically just drop the motor in and customise the wiring and hoses and a few other things. Finding all the needed parts is the hard part, where as a complete motor has everything you need.

A lot of custom work is needed to get everything hooked up, I had to make custon cooling hoses where the heater core is, I had to cut the throttel cable bracket to clear the hoses so I could not use the cruise control cable, so no cruise. The EGR needed to be deleted sicne there is very little room where it hooks up, the engien is very close to the firewall, I may try and get it to work with customising the EGR just for emissions, not sure yet. You will also need a very good tune to make this setup work, trust me, I have been there. [img]images/smiles/icon_smile.gif[/img] You will need to make a custom air inlet from the airfilter to the TB, thats not too hard, also if using a custom IC setup, then thats all got to be made as well, piping, brackets IC etc. The SC motor has 2 extra sensors they are the knock sensor and oil level sensor, we can live without these, and besides our mustang harness will not plug into them so we can't sue them anyways, all other sensors will work, just need to lengthen wires to reach them. With my custom IC setup I had to moive my battery to the trunk as well, but if you use the stock SC IC then you'll be fine.

How will my mustang block hold up?

Well the SC came with a stronger crank, pistons and rods to handle the extra power. The SC block is also stronger. The mustang block has proven itself to be fairly strong as well, no one has broken one yet at least. No one really knows for sure how long the mustang pistons and rods and crank will hold up to the roots setup, I have been told that the rings would be the first to go, the mustang has a higher compression ratio, but something about the location of the ringlands or something is better ont he SC pistons, don't wuote me on that, its hearsay right now. Stock SC compression is 8.5:1, I am running 9:1 with forged pistons in my setup. I have heard about guys even running above 10:1 with the roots blower but I don't think they push their motors too hard either, more for show.

I have also heard of guys runing 4.2 SC motors, with no problems, except for one guy who keeps busting cranks, SC cranks at that, I think his problem lies elsewhere though.

That list is complete. You need everything listed.
This is not a job to have someone install for you. They would need to charge an arm and a leg and they will hate you afterwards.
If you insist on supercharging, I'd suggest you look at a Procharger kit.

A garage would charge you $1500 - $2000 to do a job like that. (I'm just guessing). And count on not having your car for a while.
Count on at least $500++ to have it tuned and running.
That's asuming you have all the parts listed above. If not, little things can add up $$.
