I noticed when I had a 74 carrera 2.7 that at about 1/4 tank I'd get more H.P.'s and now that I have a 75 1.8 914 I get the same thing way better throttle response??? I doubt it's due to weight...any ideas?

My theory is this, Your engines (both of them oddly) were jetted too rich. The engines were recieving too much fuel due to the raised fuel level in the tank exerting additional PSI at the pickup in the base. With less fuel in the tank, the pressure in the lines is less, meaning less fuel in the engine. The benefit of lowered pressures is a leaner, hotter mix in the combustion chamber. I want to warn you ALL, do not allow the fuel level to get too low, if you do the engine will become dangerously lean and make expensive sounds. You may notice that it will be running at its best right before it goes boom. In fact, after reviewing all this data, My official recommendation is that none of us drive our cars ever.
Good day to you all. |
