nope

 

I don't think so. I am running the ls/vtec with a t3/t4 at 15 psi and 550cc's. I don't have any problems.

you will be fine with the stock rail.

No, ur stock fuel rail will be fine

For a LS.. You're going to need bigger than 440s if you're looking to make 300HP. My brother had a 93hatch LS boosted.. est 220whp. 450cc injectors maxed out at 7grand @ 8-9psi. This was tuned by Blundar from http://www.pgmfi.com (super honda tuning guru guy). I would start looking in the 500s or 600s.

The stock rail should be able to flow enough fuel for around 500whp.

this doesn't make sense. Those 450's shouldn't max out at only 220whp. What was this car tuned with? If its tuned with uberdata then the duty cycle percentages are somewhat off. I've heard of people running 120% duty cycle and the injectors weren't actually maxing out.

that's what i'm wondering. so should i keep my 440's or sale/trade em?

 

Isn't the stock rail/line ID good for approx. 400 hp?

 

^^^ yeah I have heard from some tunners that the stock fuel rail can hold up to like 500whp but I might be mistaken.

 

Yeah.. was tuned using Uberdata. The injectors were pretty close to being maxed out according to Dave ( Blundar ). Either way.. I would definitely go bigger than 440cc.

u think it's because of uberdata or the tuner? i'm pretty sure 440s don't max out at 220.

You're right, they don't. The stock 240's are good to almost 220whp.
