ive got the above and fuel pressure reg whats the maximum bhp you can run with these before i have to sell them and buy bigger ones. ive currently got a built 2.5 with a 20G getting used to it now. and now im looking 480/480 or even a touch more than that. are these injectors sufficient enough and would i need to change my fuel pump to a bosch one?

many thanks in advance

Are you planning on reaching 480 with meth or e85? What turbo will you use? A mate of mine is using the new s206 on his 2.5 & that should reach your target on normal fuel, I believe he is using 820s which don't break a sweat.

 

Have been told I'll need a secondary 044 pump and swirl pot for 500 plus on my 2.1, I'm using lateral 960cc injectors

 

740's are fine for 500, I use them in my 2 litre, 504 bhp at 86% and 3.4 bar fuel pressure atmo. I do use a Bosch Motorsport version of the 044 mounted in tank. You shouldn't need a swirl pot for 480.

if its just a fuel pump then thats great thanks again everyone.

smoking kills 470-480 with out meth and yes S206 is the turbo i will be going for might aswel try something a bit diffrent and see what happens im sure it will be ok ive spoken to a few people that are currently using it and they wouldnt swap it for anything else.

 

bob 500 on a 2 liter what turbo are you using?

 

Must be something big

 

The 740cc injectors are rated to around 560bhp.

What are the 740's bhp rating (and at what % IDC) when run at OEM pressure i.e 3bar with vac hose off (or c.2.5 - 2.7bar when it's connected)?

 

thanks again everyone 560 thats a lot 2 much for my needs but nice to know
