Page 1 and 6 of the Injector chart sticky, under the Good Stuff. Both pages have charts for figuring out injector sizes.

Can anybody tell me what the HP rating is on the 7 hole injector series? Now I know its gna be different because of different makers but id like to get a relative idea. Thanks tater


JKidd says these 7x10s are a 50hp injector. I've also been told their a shade bigger than 5x12s but IDK.

Cross sectional area- (pi x r ^2)x # of holes
7x.010s = .0005498
5x.012s = .0005655 Hmmm...
C'mon guys, I did that in my head :lol: :lol:





Yea right :P

Most dealers call 5x14's "140 horse injectors" for some reason. It all depends on supporting mods and pump settings how much hp gain or loss you get from an injector.

Most shops use ratings for estimated HP on a 12v P7100 application. the VE will probably see around 1/2 the estimated power of the claimed p-pump rating.

The CSA is not an exact science. There are other factors at work, but it is a good ballpark way to compare.
