Default Large Injector Options?

What is available that is larger than the 60lb injectors by Motron but are not going to cause serious problems are need extras? I was told RC made 73lb injectors, but I have not been able to find them anywhere. I am thinking of going with a dual pump setup and maybe 73lb injectors and need help. I guess now, my goal is ~700 whp. Thanks in advance.

P.S. This is via a turbo setup which, to my understanding is more demanding on the fuel system.

If anyone knows any more about the 73lb injectors, please let me know. I would love a set of slightly larger injectors rather than raising fuel pressure... but only if the injectors idle great and produce all around great results. Otherwise I'll stick with the Mototrons.

I have a set of them. There are fine for everyday cruising. I did notice a decrease in mileage with them. About 6 less on the highway, and about 5 less in town then the 60's

I did go over the 1k RWHP mark with them. This was at 75psi. I have it set for 58 and it adds 1 pound of pressure for each pound of boost. NO METH

You lost 6 MPG with the injector swap?

wow, that is pretty crazy. If I am looking to make ~700 whp which setup would you go with? Right now I have a 255 racetronix pump. I was going to also add a second external pump and lines and then have to decide which injectors. Do you think I would be ok with just my 255 pump, 60's, and maybe something like a BAP? I want to make sure I have enough fuel, but I am on a budget of some sorts. If I could get away with just adding 60's and a BAP, I would do that, but if I need to add another pump, then I am sure the price difference between the 60's and 73's is negligible.

the price difference is actually pretty large. They are near 90-100 each for 72's. I am quite sure you can make 700RWHP with 60's. the racetronix and boost a pump is a good combo, probably not enough for 700 though. Instead of adding a second pump, you may want to look at a meth kit for the difference in fuel. It will get you there with no problems, and it will be much more safe.

I've made 700 rwhp with Mototron 60's, a KB BAP, and a Racetronix pump.

I will be installing a meth kit. So does that mean, the 60's, BAP, racetronix, and meth should be good to 700whp via turbo? I dont want to skimp on the fuel setup as I know that is very crucial, but I dont want to spend money unneccessarily if I dont have to. I know more is better for future upgrades, but at this point, I want to limit myself to 700 whp so I am not breaking parts left and right. Thanks again.

bump for my last question. Will 60lb Moto injectors, racetronix 255 pump, MSD or KB BAP, and a METH injection kit be sufficient for my 700whp turbo build? I will be happing with 675-700 to the wheels and want to limit myself at this level for now. Thanks in advance.
