Hi I will be running my t4 14 outdoors at Broxtowe tc track and don't know where to start with gearing at moment I've got std 84 spur (48dp) I suppose I could run (64dp) if needed.what range of pinion sizes should I get? I'm running a 17.5 motor thanks

If you are running blinky than anything between 3.1 to 3.8
I would start around 3.5.
You will need to get some smaller spurs RW offset for X Ray work perfectly
70t spur (48dp) or something close to that will be needed. Then pinions around the 40t mark to give FDR around 3.5 which should be about right for Broxtowe.

Will be running boosted 17.5 so will it be more if so whats recommended thanks
Don't know anyone that runs that, but as a guesstimate I'd start on 4.5FDR, so something around 78 spur 33 pinion. Then gear up if its okay on temp and needs more speed.
