OK how can GH motor fly a SU34V4 like mad on a 6x4 
When my 2212 2200kv on 6x4 won't fly it
What's so different ?

To truly compare setups and see why there is such a difference we would need to know all of it for each setup, brand , model, size.  Motor , esc, prop  and even battery.

Iam running Focalprice A2212 2200kv 6x4 emp prop 40amps ESC 2200MaH 30c
To get the SU34 V4 (32 in WS) I've gone up to BR2216 1400kv 8x6 wsf same battery ESC as before 
Flies adequately borderline underpowered
How does changing ESC timing effect lower kV motors?

Have you got any stronger motors such as a Turnigy 2826 6T 2200kv ? These have a higher wattage  and spinning that same 6X4 prop you will have more power, depending on the size and weight of the plane it still might not be enough. 

Do you have any 4S batteries?

What is your AUW with battery?  If you are close to 800 gr/28 oz along with the drag of a rather large plane and wingspan, you are not going to have much performance beyond just being able to fly around with the 2212 2200 size motor.  Also, the 6x4 EMP prop in my experience is a very inefficient prop, you would be better off going with a 6x4 APC style knockoff prop  https://hobbyking.com/en_us/glass-fiber-nylon-electric-ccw-6040-grey-2pcs-bag.html

I've never experimented with ESC timing on a 1400 kv motor.  Having experimented with it on 2200 kv motors, there can sometimes be a slight gain in power, at the cost of the motor running very warm and sometimes "desyncing" or skipping as you are flying around.  Often I have also had situations where the motor would cut to half power for a few seconds and the only way to reset was chop the power, hope for the best and then move the throttle forward again.  On the inexpensive 2212 2200 kv motors, you are best to leave the ESC at factory defaults.

Is the 8x6 wsf prop the recommended prop for your 1400 kv motor?  I would perhaps think an 8x4 might be better, the motor might have a much easier time spinning a prop with a slightly lower pitch, therefore bringing up your RPM and thrust, but I am just guessing as I have never run a 1400 kv motor.  

A Turnigy 2826 2200 motor is essentially the same motor as a 2212 2200 motor, no gain in watts or thrust unless you run it on 4S which you can do with the Focal Price 2212 motor, I would suggest propping down to a 6x3 EMP if that is the way you are going to go.  Hobby King/Turnigy continues to market their motors using the outside dimensions of the can/bell (in this case 28mm x 26 mm) while the rest of the world uses the stator size as the motor measurement.  A Turnigy 2826 has a 2212 size stator.

You would notice a difference if you used 45c battery, but not a great deal.
Using the 2826 2200mha with lower c rating is like running an engine with a carb from a smaller engine they just don`t discharge enough juice.
Even with a good 2212 2200 or 2700kva motor the big SU 34 v4 will be slow due to size and drag, it was designed as a trainer. The su 34 v4 is a very good plane for noodling around with and very forgiving but if you want speed you need to cut the weight and drag.
Wot, no Depron?

OK been a fiddling 8x4
Wsf on BR2216 1400 low timing is the highest wattage lowest amps
On my BigMig same engine three blade 8x6 highest timing has the best wattage but also the highest amps
So will do more fiddling and prop v timing tests as time permits
E3Scott interesting about the EMP prop I started using them after seeing RC Plane Pirate doing prop comparison tests and EMP produced more thrust at lower amperages
My SU34 V4 is ready to fly at a snip under 800grams so hence the 2212 struggles I can't get depron so this HK model foam ( which is no longer avail too) and drywall mesh foamtac fibreglass
Got some normal profile props coming so like you guys have suggested I will spin the motors up faster and test

wont fly it or just slow,as every one says its to big to be speedy,a rear mount helps a little,my SU35 rear mount was a shade under 34 inch span and nearly 30 oz not fast but aerobatic which I tend to favour over top speed.not the best filming or launching/catching my fingers on the wing tips breaking it but it stayed in place for the ole flight.

Yes that's the next course of action 
If prop size fiddling doesn't bear fruit

The basic vertical thrust test will tell you if you haven't enough or barely or rocket ship coming at you. 🙂 
4S on the 2200 motor will just about double the thrust , just careful how hard you run it.  One thing I never done yet was experiment with the lower kv motors running on 4S , might have to dust off the thrust stand. 🙂

been playing with Turnigy 2826 (2212) 2200kv on 4S for @ a year now mega fun when stuck on profile models 
RCPowers Mig29 V5 is getting the same treatment when i get some spare time to build 
slowy replacing all the ELCheapo 2212s with the turnigys 
brought some BR'S when they were cheap theyre not bad 
got some flite test airframes iam sticking the ELCheapo 2212's on got a bag of 30amp esc's cheap and all up flying under 500grams so should be fine 
its summer here and usually the calmest dawn and dusk so getting plenty of stick time in

A nice and strong efficient motor in the lower kv models is the Turnigy 2826 10T 1400kv . This is the guy I am going to put on the thrust stand on 4S and test some different props. On 3S it spins a 10X5 APC no problem and loads of thrust.
