would it be bossible to diffuse co2 through a spraybar attached to my powerhead. I am thinking of building my own spraybar out of pvc pipe so that it goes accross the back of my tank.

Yep... if you put the output of the CO2 into the intake of the powerhead, the impellar will break up the bubbles and shoot them out the spray bar. If you put the spray bar lower in the tank, the bubbles will have more contact time with the water as they float up to give them more time to diffuse.
There are more efficient ways, but this should work well for you!

right now i have the co2 going into the air input of the powerhead which seems to break up the co2 into small bubbles, the thought behind the spraybar is that the co2 will be disolved in the water current as it travels down the pipe and then into the tank.
Yep... I think it's a great thought. The spray bar will give the bubbles lots of time to contact the water and get dissolved.

IMHO injecting the CO2 into the intake side of the powerhead will work.
I do this with my pump.
Also directing the flow from the spray bar downward or horizontally will help.
I have my return jets directed downward toward the extreme corners of the tank.

This is a perfect idea, and has been proven to work on many occasions. However, don't expect to get very much dissolution within the spray bar, as the velocity of the water will almost certainly spit 99% of the bubbles into the water column before they have the chance to dissolve. This is by no means a bad thing, just be aware that you will still have micro-bubbles floating throughout the tank.
Mounting the SB low dow, as has been suggested, will give the micro-bubbles ample time to dissolve into the column.

I mounted the spraybar at the bottom of the tank, its a 46 gallon bow. And yes I get a lot of micro bubbles, my drop checker is green so it must be dissolving enough into the water.
The holes in the impeller-blades should be very small.
I checked on Barrreport. Search for Needle-Wheel and you'll find lot of information.
Reduced flow, not sure but I'd recommend to try this only if you have a spare impeller in case it doesn't work out to your expectations. Should be minimal if the holes made are small. No more than 1 mm holes I would say.
Use plier, torch and small needle or nail.
Heat up the nail or needle
Pinch small holes in each blade of the impeller, depending on the size of the impeller, 5-6 or more p/blade.
Reassemble and feed CO2 just below the intake of the powerhead.
You will find that the CO2 will be chopped to such small bubbles that you can hardly see them anymore.
