Default Looking For OEM Fuel Injector spec??? Anybody know?

Doing some headwork on a warrior, looking into maybe changing the injectors just to make sure they'll make the power I'm looking for. I'm going thur Fast.com for parts. Looking for the stock fuel injector specs. Have googled the Nippon IMP-732 and not found anything. Any of you drag racing guys messed with this??? Any help would be great

Stock: 286.3 cm3/mn @43lbs

Speedstar 399 cm3/mn @36lbs

Stock 27.3 lb/hr= 44hp/cyl max

Speedstar 45 lb/hr = 72 hp/cyl max

That 44hp/cyl true? Is that number based off of the duty cycle? A lot of people are pushing that number with basic mods.

So 50hp per cylinder isn't possible with stock injectors? Has anyone figured out an injector to use besides the S*?

Don't touch that please, your primitive intellect wouldn't understand alloys and compositions and things with... molecular structures.
