I would LOVE to do this but I don't think I have a steady enough hand for it.

If you guys dont want to mod your injectors, Crazyhorse can send them off to terry to get them drilled. Look at it this way, you can pay for professional service or chance at having to buy new injectors if you mess up.
If you do it yourself, buy at least 2 drill bits. I found that 1 drill bit goes dull after 2 injectors.

I bought 8 ...better use lots of bits and get nice clean holes every time.

Does anyone know how to convert, GPH (Gallons Per hour) into cc?
Besides:
1 Gallon = 3785.412cc

I flow tested a stock injector that I modified, and it flowed 175 Gallons Per Hour.

I'm trying to calculate that into cc terms.

So cc is Cubic Centimeters.... but at what rate?

Thanks

I don't know how you would convert it...sort weird how one has time involved and the other doesn't...go figure
unless you were to go by weight or by volume but they aren't even close

try playing with this

You gotta use lbs/hr

CC/MIN = LBS/HR X 9.71 OR LBS/HR = CC/MIN X .103

http://www.freebuck.com/tools/calculators/units.htm

plug 175 in the "Gallon" box at the bottom it comes out to .662

So does that mean it's a 662cc ?

"Wait a minute.... 175 GPH... that can't be right. There's just no way.... lol *scratches head*"

^^^ Thats what I was thinking...

gasoline ways between 5.8 and 6.5 lbs...so we'll take the average at about 6.15 lbs...which would equal about 1076.25 lbs of gasoline in an hour(weight of gallon of gas times the number of gallons per hour)...right?
so each lb of gas is equal to 615.51415 cc using value you gave above... so multiply that with number of lbs an hour and divide by sixty minutes...right??
some on check me on this please because my number is way off the scale....11040.785 cc/min
where did you get this test done? and are you sure it is gph?

I got my results from RC today. Using a .5mm drill bit and having mike (local goldsmith) do the work, resulted in two 720cc injectors and two bad ones. (they leak) Under magnification, the holes look great on every injector. So, its possible that I had two bad injectors to start with or two injectors were drilled too deep. Mike says that drilling the holes were easy and that hitting the bottom wasnt an issue. Who knows?? Crazyhorse should have his results in a week or so.
