Tactics for Cliffs of Dover.

I highly recommend Stephen Bungay’s
The Most Dangerous Enemy: A History of the Battle of Britain It’s a must have!

on that page the climb rate is shown as about the same for the standard MkI Spit, and I assume the 12lb boost model would be a lot better. Speed wise the standard Spit is slower at many altitudes, but at it's optimal altitude the Spit is faster. The 12lb boost Spit is faster than the 109s at all altitudes.

That page is extremely well sourced. Apparently the +12 boosted Spits and Hurricanes are the only ones relevant to a Battle of Britain sim.
