What Injectors are you running?

[mysticsvt]

To my knowledge Bosch no longer offers Injectors with their name on it? I know all Injectors are Bosch cores but they are handed to 3rd party vendors and they "finalize " the Injectors .

Not sure what finalizing would be. Every injector I've ever seen, made or tested here has all the parts and laser markings on them. Here is one I'm working on now...notice the Bosch emblem in the corner, "927" is the Charleston Plant, 12 is for being made around noon on Line 16, date on the bottom, part number on the terminal housing. The other side says NISSAN and has a few other markings.

Yes Bosch still sells injectors with their name on it. My buddy picked up a set for $500 new last week for his TT Cobra.

Few observations. You don't need a triple pump set up for what you're looking to do. You can take a stock pump hat and modify it by adding a 2nd feed on it and run twin 340's. That will easily support a ported Eaton setup on corn, even with a 150 shot. This is what we used to do back in the day before they made all these fancy billet fuel pump hats. I don't know what nitrous system you are looking at, but if it's a wet, make sure you don't pull fuel off the rail for the fuel solenoid to avoid a lean spike when it's activated. Find a used set of ID1050's, that should be plenty sufficient.

When you start getting to the point where you need to spend $2k+ on injectors, that is the time to start considering an aftermarket computer like the Holley or whatever you like. You can run the $600 Bosch 210's then and roll that money saved into the standalone.

Please read badcobra's advice two or three times. It is spot on.

You can easily do ID1050s for your setup. I am personally running Bosch 210s ($500) for corn and a lot of boost. I am running an MS3 Pro and the drivibility of the Bosch 210s and the MS3 Pro is insanely good, better than any injector I have ever run and I am the one tuning it.

Also make sure what ever you get your tuner can tune. I have seen some great injectors run horribly because of the shitty tuners.

Do you do outside testing or are you factory testing? When I pull my injectors to install the J2Fab intercooler I want to re flow test my 210s as the last guy assembled them backwards and tested them.

I don’t think 1050s will support 1000. Maybe I’m remembering wrong.

With a higher base pressure I bet they will. I asked my tuner 2 times which injector to go with and he told me he has tuned 1050’s to 1000 rwhp so that’s what I went with. He’s the best in New England so I trust what he says.

I was making 785hp on 80’s with a base pressure of 60 at 94% duty before upgrading.

We do inside testing. I run that department on my shift. We don’t do external injectors or I would gladly do them for you.

That's good to hear cause I will be running the same ID1050X once I install my fuel system. Who is your tuner and duty cycle?

Pete at Performance Dyno tunes my car. I am not sure my current duty cycle. With the 1050x’s I dropped my base pressure back down to 40. On 26 psi I was having spark issues with my coils, haven’t had it back on the dyno since adding new coils, but he says it will be in the 850-860 range. Makes 823hp now on 22 psi.

Dumb question, how do you raise and lower base pressure? I am assuming you adjust it on the regulator?? And is 40psi the sweet spot?

Yes on the regulator for return style. 39psi is the stock pressure.

Raising pressure will make a smaller injector “act” like a larger injector. Remember the regulator also raises pressure with boost 1:1. So 22 or whatever psi of boost raises fuel pressure the same amount.

Need to know what the fuel pumps can run at. I run the Walbro 465 pumps, which are good for 120 psi IIRC. So 60psi base +22 psi of boost becomes 82 psi of fuel pressure under WOT. I went to a larger injector to lower the duty cycle and to not strain the pumps so much. I’m just saying it can be done to make big power on the 1050x’s just like on the 80’s I used to run.

I think the FC2 or whatever the Fore reg is maxes at 80 though

Would you see more?

I cranked mine as high as it would go to check for leaks and couldn’t get over 80.

Who do I go to for ordering Bosch 210?

You have to be careful on the Bosch 210's, there are a tremendous amount of fakes out there. I and many others have bought from this eBay seller and we have verified their authenticity with Bosch USA. They come in individual Bosch boxes with the protect codes on them. Without a highly skilled tuner, you will not be able to run these on the factory ECU

Also, the injectors that Bosch sells to ID, FID, FIC, those 3rd party vendors remove the Bosch P/N's from them. Bosch 210's are ID2000's, but if you compared a brand new Bosch 210 to an ID2000 injector, you can easily see what ID does to remove the markings.

I run a Magnafuel regulator on mine. I will have to check how high it will go. Never tried maxing it out.

Bought mine from the same seller no issues so far running pump 93 and e85. Even through a bad batch of e85.

I checked that link and the description is misleading, it states these are not gasoline approved but then in another section says they are gas approved. I will contact my tuner and see what he says about them, I would prefer going with these Bosch, I may have to find another tuner if mine says no lol. How's the drivability in low speed and idle?

What Is everyone's take on pumps? Quantity wise? 2 or 3?

This has sparked my attention greatly. What are some of the advantages to doing this?

 

[01yellercobra]

The Bosch 210's are labeled for propane I believe. But lots of people run them with gas with no issue.

The 210's are low impedance. They flow the same as the ID2000's, but they're not the same injector. You either need to swap to a stand alone or run an injector driver. They're not plug and play with the stock ECU.

 

[Soap]

I was making 785hp on 80’s with a base pressure of 60 at 94% duty before upgrading.

Setting your base at 60 psi is a bandaid because your injectors are too small.

You would be stupid to try to make 1000cc injectors work at 1000HP.
