whats the Perfect boosted injector

[DKRM]

Im running dsm 450's right now at 220 whp but i wanna step it up to 350, 400 max whp what injector size would be the best not too small and not overkilled, Im looking at 750cc or 880 cc's right now, but cant find the right info on what would be the better decision

You can get a good idea here.

You could always tune your injectors with a fpr and standalone but if you do the 750's and then get even more boost happy down the road, then you'll need to shell out another $300-$350 for some new bigger size injectors.

Going bigger than usual isn't always overkill....but plan ahead on your power goals so you buy only once. Honestly it's nice to say you have a accord that is a 400HP dyno queen...but it sure won't hook up on the ground for daily driver like a STI thats for sure. Plan on some good tires and LSD.

Since ur doing the DSM thing, you could get lucky and score some EVO X injectors on e-bay for cheap. I think that will get you in the 350+ range with some good tuning and I believe they are plug n' play just like the blue/green 450s.

Lemme know how it goes!

if i went with 880cc injectors would it have any negative impact vs a 750cc injector?

anyone?? Im looking at some 880cc I would like to grab today, if they are not too big i just dont wanna get 780,s and run out of injector

You will be fine with even 680cc injectors for 400HP.

thanks

Generally, the bigger the injector, the more difficult it is to get a good idle. However, at this size, there should be no problem.

Also, there is always a market for used injectors if you do end up needing bigger.

You IDC(idle duty cycle) will be harder to get tuned in correctly with a larger injector. That being said, its really easy if you know what you are doing.

At either size injector, 400whp very doable.

Injector Dynamics 725cc injectors. Although they do not require a driver/resistor so you'd have to remove the stock resistor box.


My 2200cc Injector Dynamics injectors idle great at .15% IDC.

Yea Injector Dynamics is the way to go. New technology and alot of info with these.

awsome thanks ill look into injector dynamics!
