I have 4 550's right now. But most likely i will crave for more power soon...so should i go w/ 4 big injectors or go w/ 4 550's? I have hondata now but I'm switching to ems and i was told ems can support up to 8 injectors. now...wouldn't it be better to use 8 for fuel economy reason (the last 4 only sprays when needed).

what do ya think?

Jeff-

 

You'll still be using the same amount of fuel regardless if you have 4 or 8 injectors.

 

not at idle and light load. the 8 smaller injectors would use less.

 

well, on rx7's...they use two small injectors and two additional big injectors..i suppose it works that way on hondas too

 

i say 8 but what the hell do i know. i dont even have my dsm 440's yet

 

I'd say if you can utilize an ems to run everything, then go with the 8

 

i would go with 8. i was considering the same because idling would be easier. the only thing holding me back was having the manifold modified to accept a second rail...$$$.

 

or just get a two rail manifold.... JG/Edlebrock Victor X Manifold Group Buy

 

that would be a good solution...
too bad one wasn't available for my car.

 

btw...can hondata do 8 injectors?

 

i think it can too..but i have 2b...hate the idea of needing 4b to tune so..ems i come!

Jeff-

 

good idea...i spoke to the tech's at AEM about the EMS running 8 injectors and they were VERY convincing...so many ways to control injectors 5-8...it's CRAZY!

 

any pros and cons about this setup?

Jeff-

 

Dude, you dont need 8 injectors man. You can run (4) 1000 cc and still get some good gas mileage. It's all about the tunning!

 

Just run 4 of the 720cc Greddy injectors. Cheaper than RC's and will work from idle to 550 whp if tuned properly.

 

i also think you'll be better off running with 4 injectors...

 

tuning 1000cc injectors isn't the simplest thing in the world

i'm not saying 8 injectors is the best idea...but it sure makes the car more discreet while sitting at a light

How is having 8 injectors more discreet then having 4 high flow injectors? My motor idles like a factory honda with 720cc injectors.

 

well he's asking about 8x550cc injectors. so i'm assuming he needs more fuel than say 4x720cc. something along the lines of 1000-1100cc

 

yes...4 550's and 4 720's or bigger later on...

like how rotoary and volkswagen guys do...

better idling and better fuel consumption

Jeff-

 

720cc is a lot of fuel already, however I guess the most important question is how much HP is corporal jeff planning to make.? If he's planning to make 400-450 whp then 4x 720cc will be fine.

 

read my signature and you'll know what i'm planning to make

right now...400~450 will do (getting it done as we speak)..but soon will switch to gt35 turbine and go all out....sponsors anyone?

Jeff-

 

jeff...your on the right track!

 

i would just run 4 100cc's

 

i hope so...now after this..time to upgrade all other crap. damn it matt...more money spending!
