If you've got the latest HPI (no.48 I think) have a look in the over 2400cc RWD category. The Crown is in there at number7 with the 11.65@108. In another couple of issues it should be in at #6 with the 11.37@125, and If I pull my finger out and buy some drag radials it should go into the tens on radials no worries (it's run 11.04@125 on McRearey street tyres, but as they aren't radials it doesn't qualify)
With a bigger set of injectors and a proper plenum it should go 10.50 or better......
