For those that are interested, took the car out this weekend to santa pod for our mopar nats.
Tried the shocks on 8, tyres at 12 psi, first run off the trailer ran a new best 10.28 with a best 60ft 1.45, pulled both wheels off the floor.
Later in the day similar conditions upped the tyres to 13 psi and stiffened the right shock to 9, as the car was twisting on the line, ran another pb 10.24 with a 1.44 60 ft with even more air.
Day after ran another 1.44 with even more air but shifted too early and only ran a 10.33.
Had a starter motor issue but all in all very pleased and a great weekend.
Thanks for all the tips
Mick
