20b fuel pump

Alright, ive had this pump for like 2 years now and read like crazy on the forum,just hoping i can get a direct answer. I have a 1990 turbo rx7, going to go big single conversion. can this pump handle a ts04 turbo pushing around 15-18lbs of boost, which i think would be around 380-440rwhp.

Thanks

true but i dont like that answer, it is like saying the stock fd pump will work if you have right/"small enough" injectors. Even thoguht i dont have the answer, i would look at the stock 20b number add a little bit ~50hp and if you plan on going above that get a better FP or another one.

I've ran the 20b pump up to 20 psi. I think it starts to fall off around there. I am going to run two pumps next.
