I have the Stage 1 APR and i am still looking for more horsepower. So, will new fuel injectors help this situation and if so, what kind? Its a 2005 A4 1.8TQ Ultrasport...Thanks in advance

 

I have a set of 4 RC 370cc if you are interested. They work great up to like 20 lbs.. but i need more than that

 

y r u runin 370 cc and makin 330 hp. never heard of anyone making those numbers on such small injectors specially at 20 psi

 

my friend ran 280whp on 370cc

 

but wouldnt bosch or APR work just as well? and are there hp gains from this and how much?

 

ya but 280 is prob pushin it. the 440 can only go to 4-450

 

well im set i got my 550cc injectors

 

That doesnt really make any sense. I injectors arent just not good after a certain map level. It depends what turbo your on. IE on stock turbo the stock 210 cc aeb injectors are fine up to 22psi or so on the aeb. Also how did u make 330awhp on injectors that size? Thats theoretically impossible.

I'm running 630cc injectors so I got some headroom

Also adding just injectors will make ur car run like ****. You need proper programming as well

 

^^^ thats y i was questioning that tom. just didnt add up in the ole' noggin

 

I have a standalone EMS to manage them, but I am running like 21 psi and I make a shitload of power my injectors start to dump fuel once I get past 15 psi so i need bigger injectors to keep up with the amount of boost I run. But it theoretically is possible, because my car does it.
