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.

701's or the newer 071s ????

there a good plug but dont last too long

 

HI,

Which plug is the cooler one, and do you know what boost it can handle
without running to hot, the car is used for clubman rally events,and can the local ford dealer supply them as my dealer had no record of 701's, recommended
rs ford dealer, which were a waste the same waste of space,

thats prob cause there a old erst plug, i knew that BUT i work at fords


071 are better than pp8's and deffo dont use them on your car ( pp8's)

speak to stu/mike rainbum ect for advice as i cant give advice to tune a radio tbh

 

they are the same temperature - thr 701 is the better plug but no longer available. The 071 will do 2 bar though.

 

THANKS ALL,
