Looking good FletchQuick general question tho to all you supercharger boys. Does anyone know how much power a Rotrex uses to produce the boost for the "low boost" conversion and for the "high boost" conversion. And then how much for what ever Rich is running? ________________________________________ My old man wrote me a letter from prison once.

Not sure how much they consume power wise but they are totally unlike the compressors of old that used more power than they produced till they got going! The Rotrex one I believe uses very high revs similar to turbo RPM's and has a clever gearbox to create these speeds which uses a traction fluid to drive the components. I'm not fully conversant with how it works and i too would like to know its true efficiencies.________________________________________ Previous Peugeot - 2000(w)GTI-6, Me old China, Supercharged with working aircon! |

What I actually meant in this instance was I could switch between standard and high boost maps by simply swapping the EPROM. This was because I was driving the car with the OE engine a while before the conversion. You could in theory swap between low and high boost maps if you were to get a low boost map from Wayne Schofield tailored to a lower compression engine. |

The boost produced is identical on both conversions. The 'low boost' conversion is simply restricted at the Throttle body assembly by use of a reducer ring. The Rotrex unit is inherently less parasitic than traditional positive displacement units for example due to the use of traction drive system over traditional gear transmissions. |

The Rotrex uses the traction fluid which varies in viscosity depending on pressure driving the rolling elements inside through friction. You can get a gearbox element to mate to the Rotrex units, but then you obviously have an added transmission loss. |

96% is bloody good and one of the reasons why this conversion works so well, I suppose RichW is the other. ________________________________________ Previous Peugeot - 2000(w)GTI-6, Me old China, Supercharged with working aircon! |

A cold november evening Flywheel and clutch in place:  Decided I may as well use some new studs and bolts for the Exhaust manifold so quickly swapped them over.  Had a quick (and I mean quick) spruce up of the engine bay as well as ripping the air con pipes out. Predator must have visited overnight   The Gearbox mount had seen better days even though it was only about 2 years old. Will be refitted for now until I find a Group N mount. 'Box back on with a bit of wiggling and hooked up to the crane and ready to be refitted:  Engine is wiggled back in and secured on the top two mounts     Plumbing Pas modifications were next; Connecting up the high and low pressure hoses to the PAS pump now located down by the sump. A bit of hacksaw action sorted out the piping. All the ancilliaries and water pipes were connected up as well as vacuum pipes and wiring loom. Next up was extending the loom to reach the TB sensors. I hate wiring but forced myself to get on with it, soldering and heatshrinking the appropriate wires, and wrapping them up in insulation tape.   Mounting the traction fluid reservoir was a bit fiddly but straightforward enough.  |

Another update. Next job was mounting the beast of an Intercooler and routing the piping. This thing was very cheap from the states but look very well made Initial trial:   A few brackets, holes and bolts in strategic places and the intercooler was supported. The top brackets will probably need redoing later as theyre currently a little thin for my liking. Fully supported:  Temporary boost piping required the right mix of silicon couplers and boost pipe straights/angles.  Trial fitted the bumper. I think it looks mean   Mounting the Rotrex oil cooler was problematic since the OEM rad takes up a lot of space on the front crossmember. I had to cut off some of the plastic on the rad with a hacksaw which created just enough space. The pipes were routed from the Rotrex unit to the reservoir via the oil cooler and magnetic fluid filter. I mounted the cooler and noted the rad still wouldnt fit in the OEM mounts. After a bit of faffing, I made up some new brackets and it just about squeezed in. Im not 100% happy with the proximity of the rad and intercooler piping though. Hopefully we can route it better when I get welded up boost piping rather than silicon or just bite the bullet and buy a thinner rad.  High boost map installed...   The lower rad pipe had been leaking for a while so time to swap out the O ring:  All fluids were topped up in readyness for the startup  Another update soon... |
