550x2 1600x2 plus in addition 4x 550 injectors how would you run them

i currently have 550 in my primary and 1600 in my secondary but i also want to have 4 more additional 550 injectors added on top of my intake manifold. my question is how would i run this setup as i have the PFC and im shur it will not run them i know i can use a additional injector controller but what ECU could i use, iv been told i could use one of the microtecs but i dont think they can control the omp so what am i left with and how am i gona get my additional injectors to work.

Best regards

Erdin

microtech can control the omp haltech cant.. unless you get the advanced ones.. but forsure you going with a standalone with that setup.. dont know what model though

its just a over kill plus if i ever want to go bigger on the turbo side of things il know that the fueling will be ok. plus iv been told its better to have 4 small injectors rether then to large ones even thou i have two 1600, think its got somthing to do with the spray patten but not shur.

Thanks for the replay guys keep them coming in need to find the right ecu was thinking of the e11 but was told that there is a knew microtech on the way that could do all things im looking for any body hard any thing like this.

I'd just sell a few 550's and buy some 850's to run primary.

hay Stephen how you doing, hop things are good. Regarding the setup, i have already given the go ahead with the install so im gona go ahead with it but i think smaller injectors are easier to control as well so thats one of the other resons to.

Thanks alot every one.

I was thinking the same thing...i was just going to run 8 550's. i am using a haltech that can run all eight, but the additional cost of having injector boss' welded on, fuel rail issues...etc etc. I figured that i'm only looking for 400 hp +/- . So i am going to run 720's for primaries and something in the 900's to 1000 maybe 1200's for secondaries.

The is not need to extra boss' to be welded on, because if you get the Keith's rail kit you can run 720's primary and 1600's secondary's.

LTX12 microtech will do 3 stages, you have the standard primary and secondary map then you have a totally seperate map for the addional injectors, you can run up to 8 injectors on the 2 addionial channels if you wish.

He's still over complicating the issue.

There's no need to run so many injectors for such a low hp goal. Beside's im sure he's far from maxing out his 550/1600 anyway.

Yeah, you need to be making some pretty serious power to be maxing out 550/1600 set up (over 500 rwhp).
And even then, like a few said, just slap some 720s or better yet 850s into the primaries.
This isn't a stock ECU or crappy piggyback. A decent standalone has no problem at all controlling a setup like this with very large injectors without having any problems.

I can see ware your both coming from but i have already orderded the injectors and when i am rady for a bigger turbo and more power atlest the fueling side of things will be ok and il be no ware close to maxing out.

what happens if one of your injectors pack up when your doing a run, this why and i do know i could be wrong the other injectors could help stop you from blowing your engin up.

this willnot help keep from blowing up your motor because your programing your injectors to open and close for a specific time. if one shuts down you will not get the correct amount of fuel(even if you ran 6000cc injectors) and you run the risk of lean out.

the only way to add injectors to the upper manifold would be to weld on injector bungs

I have to agree with all those who said "You are complicating things"...unless your expecting 650+ horse power there is no need for more then 4 injectors ALSO


I believe these are the potential horse power numbers that the following injectors "could"sustain*

Fuel Pressure @ 55psi , 80% duty cycle


1600cc is 229 hp per injector x 2 = 458
1200cc is 171 hp per injector x 2 = 342
950cc is 136 hp per injector x 2 = 272
800cc is 114 hp per injector x 2 = 228
720cc is 103 hp per injector x 2 = 206
680cc is 97 hp per injector x 2 = 194
550cc is 79 hp per injector x 8 = 632
460cc is 66 hp per injector x 4 = 264

Ok maybe i am complicating things but im still gona run this set up and i appreciate all the veiws and information everyone has giving but i am planing to drag race so may be that would help people understand way i want so many injectors and beside that i like to be different.
i think it would better to try and keep injector cycle lower as u can for reliability resones cus from what i have hared when you start increasing the injector cycle the injectos can over heat.
But getting back to the main question iam Left with The E11 from Hatech or the LTX12 which From what iv hard dosent run the OMP.

Thanks again to every one
