Cosworth losing power
Hi, I have a 2WD sapphire cosworth which I have owed for the past year or so, it has developed a problem lately, it drives fine but when on boost it is just coming towards fully power and then it drops off as if something is letting off the pressure, I let off the throttle and back on it comes to the same point and then it cuts again, I have been reading on some of the threads and the "AMAL" valve could be the problem. My problem is I cannot find the amal valve on my car, where is this located on a 2WD sapphire. My car also has been to well lane turbo at some stage and I have read on other post that they remove the amal valve. Does anyone know if this is true and if they removed it what would be used to control the boost. Does anyone have any other suggestions as to what may be causing this problem. I am living in Ireland and most garages here don't know one end of a cosworth from the other. Thanks in advance
