Would running an 85mm on 98RON with a Harrop be right on the limit of the standard injectors?

When I spoke with Harrop at the time (and a couple of trusted Harrop tuners), the general feeling was that 85mm was a small step too far without beginning to take those other factors into consideration... so they advised against it.
Now they might have been trying to be "responsibly conservative" in their thinking, but I figured if I'm asking for advice from the experts.... I should probably take it.
BTW you won't be disappointed with the power as it comes... its great fun!
