My Supercharger Project
Thought some of you might be interested in my supercharger project.
Its based on a B20F and uses a Rotrex supercharger mounted where the alternator used to sit. I have fabricated my own bracket out of aluminium and turned a new crank pulley incorporating a 8 groove pully to drive the Rotrex. Idler pulleys are from a Sierra Cosworth. I have junked the D Jetronic system (all parts available if anyone needs them). Instead i am using a Megasquirt v2.5 to manage fuel and ignition. Original D Jet injectors replaced with Cosworth yellow injectors which use the same mounting hardware. Throttle position sensor replaced with a Bosch unit from a Volvo 850. A Ford air temperature sensor fitted to the inlet manifold. A Ford water temperature sensor fitted into the head. A wide band Lambda sensor is mounted in the Simonz 4 branch exhaust manifold. A manifold absolute pressure sensor is integral on the Megasquirt board. The original engine driven fuel pump supplies a Swirl Pot mounted under the bonnet. From the swirl pot a Bosch high pressure pump feeds the injectors via a FSE fuel pressure regulator. This returns to the swirl pot and the swirl pot returns to the tank. Ignition uses the Ford EDIS wasted spark system. A 36-1 trigger wheel is mounted on the crank pulley and is witnessed by a Ford VR sensor. This supplies timing signals back to the Megasquirt. The outlet from the spercharger feeds the inlet via a Sierra Cosworth intercooler which fits nicely in front of the radiator. I just need to wire it all up now and then see how it goes. |

Yes bought the Rotrex new. About £1400 (ouch). I was going to use
an Eaton M45 which i bought off ebay for £150 but it wasnt going to work out as well as the Rotrex installation. Rotrex so easy to fit, same size as the alternator it replaced. |

alternator
you probbaly know this already..or have sorted an alternative solution but will tell ya anyway.
Having removed the alternator you will need an alternative, so have you seen the alternators made by Powerlite which are direct replacements for old dynamos? Might just fit onto the old dynamo mounts under you manifolds |

Temp indicator sticker?
Hi,
Is this a temperature indicator sticker on the head plug? Cool idea. Lets you know about the head temperature immediately. Very nice project. Hope to hear more soon... How high have you set the compression? What cam do you use? Cheers, Bruno |

I have used a nice little Nippon Denso alternator as used on Daihatsu's. It
takes up very little space and has a built in regulator. I made a rose jointed tensioner and an aluminium space to align the pullys |
