Just bought a set of pfr7b's,and heard that they should be set to right gap,
the car will hopefully be runnin arround 340bhp at arround 1.3-1.4 bar boost,
mapping next week,
so does anyone know the correct gap size please in mm?

 

bout .6 mm is good

 

I'd say 0.7mm

 

I have mine set at 0.6mm

 

Now im stuffed 0,6 or 0.7?
what would happen anyway if say the gap was too small or too big?
has it really got too be exact?

 

Too small causes idling problems, too large causes problems when giving ti some.
0.6 or 0.7 are about right, you probably wont notice the difference between them.

 

id say 0.65 then you def wont be far wrong lol!!

 

0.6mm is what you want then when you get in the boost hard you will not get blow by?
