is there any way i can test my boost valve? when i go full throtle my gauge only seems to go to .2 - .4 bar
do you mean how can you test your boost gauge? Only way really is to put it on another boosted car. Or hook it up to a compressor somehow.
How much boost are you expecting to see?
not sure really, 51mm throttle body, gt inlet manifold 65mm pulley and full blend charger should be seeing more than .4bar i reckon
yeah should be more like 0.9-1.0 bar really.
