There's a lot of good information on fueling here. After reading thru this thread, I know fuel lingo should always be talked about in regards to pressure, not hp; just as the holding capacity of a clutch should be talked about in tq, not hp. But for the majority of us, hp is kind of the universal language when we talk about the limits of certain components. And quite frankly, its a lot easier to compare on a basic level that most of us are wanting to know to see what parts are compatible with our goals. So i get hatrickstu refusing to respond to riceball's "experience" but come on, for the sake of figuring this all out we can generally attach a hp figure to the various pumps. Sure it may not be technically correct and can vary +/-20% considering all other factors, but at least it'll get us in the general ballpark. Hell, even when it comes to clutches we all know the oem/act combo will hold somewhere around 320-350wtq, which in most instances equates to roughly 500whp give or take. I'm not saying this is the right way, just saying for the sake of conversation i dont think we need to shoot any input down due to technicalities unless they're WAY off or straight up wrong. But even based on my experience, the aem320 pump on e85 ran out of juice on my buddy's evo at 650whp and 511wtq (hes on 2000cc inj). Which is what I'm hoping to hit next. So its not that far off to say the walbro450 should be rated to around 700whp, despite other factors such as base fuel pressure, injectors, etc. just my .02cents

Get the five o injectors 620hp + they're affordable . And idles smooth on 91 at 1500rpm.... My set up is around 600+hp completely unopened block.... Ask ap1 chief tuner and my tuner dave from import Auto pros would agree.

I always carry an extra 5 gallons of e85 for whatever. U don't want to run 91 on low boost anyways I'm on 19 psi on e85

Wally 450 all day. impressive intank pump.

Make sure you use good wire and terminals/Relay for the rewire too.

I would leave it alone if you aren't looking to make big bump up in power. That pump is just fine at that level

It just occurred to me that I haven't left a means of contacting me at work (T1 Race Development/Injector Dynamics) if any of you guys have fuel system related questions. Had another member reach out to me about some ID1300 questions. I am not trying to sell shit, just offer advice if you need it. I certainly do not have all the answers, but if I don't have your answer I will do my best to find out for you.

Feel free to call me 214-607-9022 ext 302.

thats awesome dude. hopefully questions can also be in regards to products outside of ID products...

I am not going to assist with other brand injectors for obvious reasons, but I can help with various fuel pumps we have experience with
