Working on it Gotta find the pulley first as I put it somewhere safe, and usually that means it takes ages to remember where it is hid. Then check the size and get a new belt. Hmmm... seems the memory is not what it was
Just dug out my order for the pulleys and it seems I wavered a bit... and actually ordered 1@105 and 1@87 dia. That changes the expected boost at 7600rpm to 57kPa (8.4psi) for the 105 pulley and 88kPa (12.9psi) for the 87 pulley. So still short of target, but creeping up on itThe Sprintex S5-210 is rated at 940cc/rev. From memory my crank pulley is 130 dia and the s/c pulleys are 110, 90 and 75 dia. So ratios of 1.18, 1.44 and 1.73:1 respectively. According to the old Sprintex calculator, at 7600rpm this should give 50kPa, 82kPa and 117kPa of boost, give or take a few kPa.
Should have all the bits for the new intake by Friday so I can start work on that over the weekend.
