Hello, thanks for the photos, it is easier.
I understand that you have to make a very homemade adaptation.
I did not know anything about superchargers (the ones that move with the A / C belt)
These days I have learned that the manufacturer gives the maximum revolutions, the maximum working pressure, the capacity and playing with the ratio of the pulleys it is necessary to make a formula that gives the working pressure.
That's right?
The car ECU should not change anything?
The injection: pump and injectors of more capacity? nothing else?
I have seen three types of adaptation:
1º Using tubes, continue using the UIM
2nd Modifying the UIM
3º Using a LIM to Charger adapter
This 3rd option seems to me more interesting and laborious but I think there is in our cougar about 12cm + - between the LIM and the bonnet, and there is little space.
Copied from a manual:
"How much boost will I get? The wide-open throttle boost of a roots blower will depend on the displacement of the engine, the
displacement of the blower, and the drive ratio of the blower.
Changing the blower driven pulley (the upper pulley) changes the drive ratio and therefore changes the boost. Other factors, such as
camshaft timing, valve size, and port size will also change the wide-open throttle boost. Check with the Weiand supercharger
catalog or technical service to get the specific boost level you need.
NOTE: The equation for figuring boost with a certain size blower on a certain size engine, and different pulley combinations are as
follows:
(25.58) x (Blower Displacement) x (Blower Drive Ratio)
Engine Cubic Inch Displacement - 14.7 = Boost
EXAMPLE: 350 cu. In. with a 144 blower and 1.95 - 1 drive
25.58 x 144 x 1.95 350 = 20.52 - 14.7 = 5.82 psi of boost
BLOWER DISPLACEMENTS (cubic inch displacement for one revolution of rotors)
142 = 142
144 = 144
174 = 174
177 = 177
250 = 250
256 = 256 "
I think I have a problem with so much imperial measure
I would like to learn why they are very unknown here and although the new 1.4 TSI engines use it and there are already many superchargers of these cars in the scrapyards at an economical price I can not find information of its characteristics
Give 122cv per 1000cm3
But I don't think they live long ...
