Default 700HP injector question

I am in a toss up between 1000,1200(rc), and 1600cc


I am shooting for 700+ will the 1200's support that?
(a1000 and 10an feed 6an return)

1200's are double the cost of 1000's or 1600's, i say go with 1600's for 700+. I use them and they are the same price pretty much as the 1000's.

Does 700+ mean 720, or 850?

http://www.rceng.com/technical.htm

(700 x .50) / (4 x .80) = 109.375
109.375 x 10.5 = 1148.4375

1148 rounds up to 1200.

Note: Brake-specific fuel consumption (BSFC) and duty cycle are NOT fixed values. They are dependent on efficiencies of several aspects within the engine. The formula provided by RC Engineering is a "rule-of-thumb" and is to be followed as such. Generally speaking, it's better to have a little too much injector than not enough injector.

1200's will be more than enough, and still not be a pain in the *** to tune like the 1600's
