I’d like to use this thread to document the pains and gains of adding a roots-type M-90 supercharger to my 2001 V6 Mustang. The project has started already by purchasing a 1990 Thunderbird Super Coupe engine (in parts) for $150. The plan is to revamp the Mustang lower intake to support an inverted blower and fabricate some kind of water-to-air intercooler to set inside the intake manifold. I’d like to track the cost and effort in this form as well as tap into everyone’s great knowledge during the project.
Being that I have no real time requirement for this, attaching a date to it is pointless. I just want to get it working and make it right.
Here’s the planned sequence of events:
1. Collect all the parts
2. Get another Mustang lower intake to chop up and construct the custom intake while I can still drive my pony around town.
3. Install the components in a stepped approach…
I.E. new gauges, MAF, injectors, water pump, crank pulley, computer… could all (I think) be added without the blower being installed.
4. Install the custom intake and blower.
5. Tune
Their trying to add a split-port Mustang engine to a Thunderbird and keep the supercharger.
However they had some very good pictures of my lower intake. The current plan is to rid the intake of the EGR passage and chop off the 12 stacks. Note, I must be very careful not to cut into the water passage, but the rest of the intake must be gutted out to hold the inter cooler
it won't be worth the effort when the procharger is on the market. procharger will make more HP but the roots will probably beat it in torque.
too much work to justify the gains. if you want HP and torque just turbo it. www.tmaturbo.com
a heavily ported singleport head with the supercoupe setup would be easier to do and make really big power
turbo or procharger on a splitport with a healthy rpm mustangs cam and supersix SSX splitport upper on a supersix or rpm lower will own an M90 setup on a ported splitport

This forum is for tracking the project of installing the supercharger stated in the first post… a discussion of which supercharger is better or worth the work is for another thread.
I've considered the facts and I understand a Centrifugal blower (I.E. Powerdyne, and ProCharger) can out perform Compression-type Superchargers (like what I am installing) but "worth" is all a matter of prospective. I have the roots blower in my garage and I have the time do the work myself. I don't have 2 or 3K to invest in a new Centrifugal blower and I feel the end result will be WELL worth it.
See http://www.powerdyne.com/tech.htm for info on why people would choose the other type of blower and if you would like to discuss this issue more lets do it in another thread.
besides, some people want that power right off the line and don't want to wait until 3000rpm for that centrifugal to spool up before it even starts making any boost.

Thanks,
you will have over $3000 invested after it's all said and done.
i wish you luck and hope you attain your goals with the M-90 kit for the splitport

i don't know what superchargers you have experience with but my procharger has about 2lbs of boost 1800rpms and doesn't take long at all for boost to build. any torque deficiencies down low are handled by 3.73 or 4.10 gearing
sure it doesn't equal a positive displacement blower but any advantage the roots has down low is quickly given up by about 3500 and the cent blower has the wicked top end charge instead of the fall on it's face on top roots

i don't get any boost until about 3000rpm on my vortech. i can stick the car in 2nd and start moving from 10mph with the pedal to the floor. you don't feel anything kick you back a little until i reach about 3000rpm.
