Hi all!
Who am i? I l’‚Âve in Sweden, and work at Siemens industrial steam turbines as a design and development engineer.
Previosly i worked at Scania Buses as a design engineer. During that time i worked with the powerful CAD-system CATIA. Since my dream was to design and build a seven-like sportscar, i used CATIA to make a 3-D model of "my" car. A few changes here and there until i was satisfied with the design, and then made drawing for the chassi and the body.
It took five years, and the result is seen on the pictures. It‚´s made as a one-off, but i still have the moulds in case a body part is damaged for some reason....
The powertrain is from a Fiat 124 sport coup’‚©. It‚´s a 1756 TC, turbo converted. I have installed 132 1800 pistons to get a proper CR for the turbo. During the winter i have installed a Megasquirt&Spark system along with a custommade intake and intercooler. The unit runs ok for now (street use) but later i want to fine tune it on a rolling road dyno before taking it to track. I run approx. 0.5 bar boost at the moment, but when cooling problem is solved it will be raised toabout 1.0 bar.
Cooling problem, it‚´s really gives me a headache.
I use a Volvo 460 radiator and fan, internal thermostat and an expansion tank. Problem is that i have to use the fan during low load driving at normal speeds, otherwise the temperature climbs beyond boiling point. It also build up a tremendous pressure. It blow the hoses off. Yesterday i tryed to run without the thermostat in case it might work as a restriction for the flow. But there was no improvement.
Tonight i will install a new water pump, check all hoses and connections so there is nothing stopping the flow, like a sock or a rat......
One other thing is that the oulet hose from the head could not be filled with water, because if i do there is to little free volume in the tank for expansion. If i fill the tank with so much water that the hose is filled, when engine warms up the water will pour from the tank cap. The tank is from a Volvo, and should be sufficient if filled to "MAX" level mark.
Any thoughts, anyone?
