When choosing a clutch you always have to take into account that the power rating of a clutch is while the car is in motion while the torque is applied. When the load is increased like it is when the car is launched the amount of torque the clutch will see can go up 50-75% on a AWD car.
The injectors might be good up to 7bar, Bosch even states that some of their newer injectors are even good to up to 8 bar. But the problem is that most people that drive their cars on the street don't have the fuel pump setup to handle running that high of a fuel pressure since the pumps flow decreases as the pressure goes up and on some pumps that flow decreases at a faster rate. The better solution is to run the right size injectors to run a base fuel pressure around 3-3.5 bar if there are plans to run over 30psi of boost. Only time it is a good idea to run a much higher fuel pressure is when trying to keep a safe pressure differential while running a static fuel pressure.
I bought the 8 puck because I felt that I won't have that stock feel on the clutch pedal with the 6 puck, but later I'm going to switch to the FX700. Much later. Lol!
Do you know how much fuel pressure can an 044 fuel pump handle? I feel it can be the best single inline fuel pump you can get? I haven't' really heard of other pumps being better, but I could be wrong.
