injectors good for 450bhp - 500bhp
 

What injectors are good for these sort of figures?

And what should 550cc's max out at?

550s will see just over 400, you would need 740s for 450+

As above but there is a lot of different variables depending on your fuel set up,i.e uprated FPR,uprated fuel pump,external fuel pump with swirl pot set up,and what duty cycle % you will be looking to run your injectors at,you don't really want your injectors maxed out for your desired bhp so give your self some headroom when making your choice,as banny has said 740cc or there abouts would be my preferred choice.SJ.

Cheers guys, what sort of price am i looking at for a set of 740cc second hand. My mate also did say i need to get a FPR..

Mark @ Lateral performance modify Subaru injectors to run certain CC maybe a chat with him might be on the cards but price wise second hand from £150 upwards.SJ.

Cheers SJ i forgot about Mark.. :)

Hi Tyler

You will need as above 740cc,with those we run 490bhp and has copped nicely like with V-Power and methanol plus with NOS

And as above speak with Mark@Lateral Performance about the reflowing yours injectors to higher cc or speak with Paul@Zen Performance about their injectors

Jura

Thanks Jura, appreciated.

Are you running a FPR?

Hi Tyler

Yes we run FPR with the Fuel rails etc and Fuel pressure has been set at 2.0bar on idle and on full boost has raised up to 3.8bar

Jura

Cheers Jura, what FPR are you using?

Is Sard any good?

Sard is one of if not the best :)

Hi Tyler

I've never used SARD,we are using Fuelab and we are been very happy with Fuelab



Jura

Tyler fuelab is where you want to be at,Sard do make good FPR but there is so much fAKE Sard FPR about you don't know what your getting I have had a fuelab on my own car now for seven years and it has never giving me any problems.SJ.

Thanks Jura


Ok i will have a look, thanks again mate. Been offered a Sard limited edition brand new for £120, £150 brand new i have been told, i have no clue about these at all.

Hi Tyler

Speak with Alyn@AS Performance about the Fuelab FPR


Jura

This might be of some help mate.http://www.more-japan.com/blogs/2012...re-regulators/SJ.

Guys you are both legends, really appreciated. I have ordered some parallel fuel rails from cdf racing and will get the fpr at some point.. Then just need to either send my injectors off or send mine off :)

Thanks again
