What fuel pump should I go with
Im shooting for 400hp out of my Evo. Would a 320lph fuel pump be overkill or would it be fine? Also, what size injectors should i use?

It wouldnt be over kill. But a 255 wally would do the job just as well. Your injector question im sure will get blown apart by guys on here saying its to vague of a question. If ur ever thinking about running e85 go bigger. Im gonna be running 1450 fics for my 500whp e85 tune but gonna also use em for 93 pump 450whp tune as well. Id go bigger rite away if ur gonna make more whp when it comez to the injectors. As for the pump alota guys will say get a double pumper but if ur not going above 500whp a single wallly will work. As long as u have a good tuner. Id ask ur tuner what he recommends for your target whp. Seems to me each tuner prefers different injectors. Im geussing thats jist cuz their more comfortable or have more experience with their suggested injectors.Thats my .02 but im sure otherz will chime in saying otherwise. Good luck with ur build man.

Hello
If you use 1450 injectors you will need 336LPH pump to support that size injector. I think for the HP you are looking for (400} on 93 or e85 1250cc you will need300 lph to support the injectors your 320 will do the job just fine . If i can be of any help including selling Fuel Pump and injectors i would be happy to do so. You will see my prices are the best around . Keep in mind these numbers are calculated on Static Flow of the injectors

If all your looking for is 400 whp the 320 is a little big but is fine, its leaves room for future mods. You can run a 255 lph walbro with some nice 1000 cc injectors such as pte or injector dynamics (id) on 93 oct and still have room to add some more power later. Like mentioned before lots of tuners have their preference for pumps and injectors they like best or had good results with.

Haha. Thats funny my tuner has tuned many cars on e85 with a single 255lph wally with 1450s. There harder to dial in but when u get it you will have a nice setup. So the vendor above is wrong. And i dont have a problem saying it cuz that is my setup for e85 and i pull 500whp from it. all safely.
Just proves that when getting advice, yes vendors can be helpful but sometimes they just try and sell u their product that they need to move. Although the injector sizes they recommended will work for your setup. Again good luck with ur build.

I didn't want to say anything ,but you did. I have always heard that a 255 wally can support 550-600 whp on 93 oct. with proper injectors of coarse. As a matter a fact I made about 386 whp on a 255 wally, 680 cc pte running meth. I know the meth does help but still almost 400 whp with little 680 cc injectors and the idc was still under 80%.

injectors
I think you really miss understand what i said . I didn't question you tuners ability to tune an injector that is too big for the application . I sized the pump for the injector size at static flow which means 100% duty cycle . I would be willing to bet your 1450 injectors at 500HP run approx 65 to 70 % duty cycle . the correct size injector for your 500 wheel HP is approx 1100cc if you multiply that by 4 that will give you the total cc then convert it to LPH and multiply by 60 that will give you the LPH you need for that injector running at static or 100% duty cycle . Which it wont run there for your power . So my point is YOUR INJECTORS are TOO big for your application .
Dont take my word for that ask your tuner if i am wrong in my suggestion to this guy asking for help . My suggestion was not FUNNY you are
