When I said Typhoon, I meant all variations.
Tempest is a variation of the standard Typhoon...which yes is faster then it's standard base model.
The 109K4 or 190D-9 to my knowledge cannot catch a Typhoon or a Tempest 6k to deck (which is where most fights occur on average).
Then you said "lots of other planes above 5k...." .....planes that are faster then the Typhoon?
Name them please!
The Tempest is so different to the Typhoon that I certainly would not call it a variation. It's not only faster by a huge margin (about 20mph), but it turns better and has a decent roll rate, quite contrary to the Typhoon. And last but not least more pure powwer & acceleration, the Tempest has a more than 1200 ft/min bigger climbrate on deck. There is a reason that the Typhoon has usually a k/d between 6 and 7 and the Typhoon around 1.5 ...
You can and have to fly the Tempest in a very different way.
At Sea Level, D-9, K-4 and Typhoon have about the same speed: D-9 ~377 mph, Tiffie & K-4 ~ 370 mph. It all depends on initial energy, but note that the german planes have almost double WEP endurance.
And if a D-9 or K-4 running from a Typhoon and the Tiffies energy surplus is not too big, they can just steadly climb away.
And here are some planes faster than Typhoon:
La-7: Faster at all altitudes but 13-18k
109K-4: much faster at any alt above 5k
P51D: Only 3-4 mph slower under 7k, faster at all alts above that
109D-9: Slightly faster than Tiffie up to 6k, way faster above that
Spit XIV: faster above 6k
F4U-4: 10mph faster on deck, and faster at all alts above 7k
P47-N: faster above 7.5k
Yak9-U: faster from about 6.5k up;)
EDIT: I would recommend you'd look at those speed charts again. And use your glasses this time...

Even on those HTC charts you can see that the Typh WEP speed on deck is under 375mph, the LA well above...
at 10K, the graphs clearly show 109K max speed around 415mph vs. Tiffies 380mph:
