someone achieving 300+rwkw with only and edit!

I am picking up my car on the 11th and it is going straight in to get a few goodies to help it go a little quicker!

What is the maximum injector duty cycle people run on the injectors before upgrading?

The reason I ask this is beacause on the wrx I was told to change them as soon as they went over 85% duty cycle as the injectors started to loose control.

I have heard comments about people running nearly 100% why is this?

Thanks

Only 2 days to go before I pick up my blueprinted "T" , then it is straight off to the work shop to get the edit fitted and tuned, injectors resized, fuel pump modified,CAI fitted and that should just about do it for now!

Will let everyone know the results, I have been told I can watch the work being carried out which I am very interested but working a 12 hour night shift on the 10th is going to make it hard to stay awake.

300rwkw on a dyno dynamics in shoot 6F is just BS on stock injectors. The highest I have seen is around 255-260rwkw on stock injectors and even then it would have seen 100% duty cycle.

The reason most tuners say not run over 85% DC is to allow for the extra airflow that may be seen on a colder night or a condition where the ECU is trying to add fuel for some particular correction.

Please, Please, Please do a search on this topic, as back when we were still learning and developing these cars to what they are today there was mass amounts of findings posted up on this forum by people such as Geea and Eugene.

These guys put in alot of time and effort to source the correct injectors. In line with people such as APS who conducted various testing of different injectors we worked out pretty early on limits and opportunities.

The forum is here for knowledge as much as anything so please put some time aside and make use of the information that's on here.

Yes these cars have come a long way in only a couple of years however what alot of the newer forum members do not know is alot of the basic principals still apply.

If you want to safely run your T with higher rwkw's you will see 260rwkw comfortably with stock injectors. Personally from the testing I was involved in you can take them further but after seeing numerous testing done on different injectors I would not go much past this. Do not forget that once again Manual cars show higher power readings than Auto's so yo may want to factor this in. From an auto perspective I would be saying 245rwkw onwards, however with the varying limitations of each car, we have seen very different results. Work on a general figure.

If you are going to upgrade your injectors Bosch 968's have been tested and tried time and time again to be the best choice. (Eugene can sorce these from OS however they have a slightly different code)

If you want drilled injectors or other optional injectors that are offerred by tuners, they will work however, will only get you to a certain power level before they will need to be changed to 968's which can run over 400rwkw.

I ran 260rwkw confortably with stock injectors, Bosch 968's took me to 274rwkw and so on from there. Do not forget different tuners do different tunes and different dyno's get different readings so if you work on a general figure you will stay safe.

You might as well learn from the experiences of some of the pioneers of the forum which will save you time and money. If you want to push the limits and find possibly the hard way it's your choice.

Personally with that much money in a car I would air on the side of caution knowing that you can confortably give the car hell without something failing terribly. BTW it's adviseable if you put in bigger injectors replace the fuel pump as generally the stock one may fail (and has done) due to increased demand etc.

Always air on the side of caution with components and you will not go wrong when pushing a mass produced car to these power levels.

Good Luck

No, no, no!!!!

New injectors & new fuel pump, not this modified crap, Eugene or Bosch 968 as JB suggested & a bigger fuel pump.

Buy new & feel no pain & have a totally reversible scenario.

Russ

how much are eugenes injectors!

what should I be paying for some injectors

new fuel pump

CAI

and a CAPA that I am supplying to be fitted and tuned?

somewhere between 2500 and 3000 would be my estimate on price but personally I wuld add some valve springs to the list to be safe and save frustration further on

these injectors are the drilled out nizpro ones! are they any good?

I do not want to be a pain in the neck and tell the tuner that I do not want the work done now, but I also need my car to be reliable!

Nah half that!!!!

around $1500 for injectors, cai, Walbro pump & tune.

I wouldn't buy drilled out injectors, we're not talking old carby jets.. Get the proper injectors, quad orifice with a split spray pattern

Russ

WOW only $1500 for all that!

that and a little more was what I was looking at anyway, starting to get confused and want to do it all correctly!

Eugene's Injectors

here have a look!

these are the injectors to get, or the Bosch 968.

just remember, you're the customer. Tell them what you want!!!

As for CAI, you can pick up the typhoon one as a spare part from ford

Cheers
