Hey guys im planning on a bnr stage four turbo upgrade and want to know if i go with 720's on all four injectors will that be sufficient or will I need to go bigger? im only shooting for 300-350hp

 

Yes

 

300? probably
350? probably not

 

Really? Who is tuning your car? Ask them. Also, talk to Brian at BNR. He will tell you exactly what you need. If your tuner specifies something else, go with what your tuner wants. If you are doing the tuning, you should know what your fuel requirements are.

 

People with stage 1's have dyno'd around 300whp. With a stage 4 he shouldn't have a problem with 350whp+ given that he has a tuned standalone, according to what the BNR site says anyway.

 

If you're only shooting for 300-350 why are you getting a stage 4?

a bigger turbo isn't better, get one that's properly sized for your desired hp.

 

getting a stage four for the future when i will be aiming for a higher hp and and have the funds to do so

 

what are you using for fuel management?

 

rtek 2.1

 

Talk with BRYAN..I did..
he's a pretty knowledgeable guy...well maybe NOT pretty,,,haha!

 

a stage 1 bnr should be good to hit about 300hp..

 

I was referring to the 720/720 setup

 

so 720/720 will be sufficient or should i go with 720/1600?

 

you can't do 1680's very well without a standalone that will give you more precise control over injector staging.

 

I talked to Brian from BNR last week and I was told that 4x720's would be enough for a stage 2. Would it really be enough for a stage 4?

 

^ maybe if you cranked up the fuel pressure...

 

Possibly 5-10 psi?

 

what's a good site to pick up new injectors? kgparts?

 

720/1000 Good for 350hp
