SC with DEK injectors and no FMU

OC_Nooby · 09-21-2009, 02:38 AM

Hey

I bought a supercharger kit that's on it way and was wondering with 11 pounds of boost and no FMU will I be able to run it tuned via Emanage Ultimate?

I currently have the 00vi with DEK injectors which are 290cc if im correct.

Thanks

As long as you have the Emanage for tuning you would not need an FMU no matter what your boost pressure. However, I do not know if the stock injectors are adequate for the power you will be producing at 11psi. You could get away with it if you got some kind of rising rate fuel pressure regulator to bump up fuel pressure.

congrats on the supercharger

IMO, you're gonna need bigger injectors for 11psi if you want to do it right and avoid installing a FMU.

What size would be good?

Would I run lean with the dek injectors? or just wont be able to trully get as much hp out of it.

Dont forget Chris, im running 11psi on stock DE-K injectors ;D

YEs but you are maxing those things out. Do it right and get bigger ones. And you might want to thing of a 255lph HP fule pump. The stock will NOT make it past 6-7lbs. Believe me.

370cc minimum to 440cc minimum, 550cc maximum.

Run the serious possibility of running lean. Wanna take that chance???

I sure as hell wouldn't try it. Good chance that you'll toast the motor if you try.

I agree, personally Id go with the 440's.

Get bigger injectors. and no question about it, you NEED a fuel pump, dont use the stock one. And if you cant get injectors for any reason at LEAST get an FMU.

That i know.. i've been lurking around for a set of good injectors for a decent price. But until then, my fmu setup will suffice without romping on the pedal too much.

To the OP, if youre going to use an FMU for the time being until you can get bigger injectors to elimate the fmu, get a 8:1 disk and you'll be set.

OC_Nooby · 09-22-2009, 02:57 PM

Whats my options when it comes to brands of injectors? I'll go with 440cc, and I guess I need the fuel pump aswell...

*The Wizard* · 09-22-2009, 03:04 PM

Go with DW injectors.

There are two sets on my350 for sale, one is 440cc and the other is 600cc (different sellers), I think both are used, but they were reasonably priced.

wow, your running an fmu right?
i ran 5-6 psi on dek injectors and was starting to max them out (9-10afr was 95 -100% DC at 5500rpm), i've added an fmu (6:1) and run 8.5psi now, not sure exactly what the DC of the injectors are now but afr is about 11

plus, the bigger the injectors, the richer the tune you can have, which means the more advanced the timing can be.. which is where you make all your power on a 3.0lt

OC_Nooby · 09-23-2009, 09:21 PM

well im getting an fmu and a regulator. So I can keep the DEK injectors and start to save up money for 440cc ones which would be within a month.

Yeah but you dont want to run too rich.
And yes, when you begin advancing timing you can richen the tune up a bit to avoid detonation but without seeing your power outputs how do you know just where in the powerband to advance timing and by how much to yeild the best gains?
