rite lads have an issue with the car. i supercharged my is200 lately.
wired in a patrick black box
used a 140mm pulley on the water pump
dw 300 series fuel pump
fuel pressure reg
used a dumpvalve as a blow off and blocked up the bypass

when cold she runs the finest. when she warms up the front mount gets seriously hot and she dies the minute i sink the boot.

anyone know what the problem might be?? if ye add me on facebook...."lexibreak" ye will see pics of my build.

all help appreciated as im at my witts end with it !! Smile

Why did u block up bypass? Surely without that she will run to hot. Why not refit the bypass and bov see how that goes
