HI,

My mate has just bought a escort cosworth built as rally car
with a mix of grpn/a parts, with grpA, air restictor, turbo set for
2,bar max boost, anyone know what boost figure ,AGPR701C, are good for, tried champion 7c & 9's, but seem to wisk up a lot if not driven hard
all the time, pp8 ok up to 1.6bar, maybe pp9's will do the job,
if still available, it is running on grpA regulations, p8, with greys,(403's)
air to air, boost control.
