jax04's 1991FC-5.3-S475-PowerGlide-Dominator Street machine!

[jax04]

are you planning to gut this car out too or keep it semi street friendly?

Keeping the interior as you see it, clean and comfy

Looks slow. Is that an L33?

LM4, It is slow, but my  makes up for it 

You need to buy those Vette LS2 manifolds I have for sale and do your hot-side like Zach's.

  ive got as nice set that ive been using for awhile, im going to give them a go first, if they dont pan out, ill look to the vette manifolds.

Oh, i did lie about one thing, i will be taking the seats out in favor of my padded kirkeys.

are those gray s4 leather seats?

Yes, back off! My car has 1.5 of those factory.. I need 2 ..

Few questions, maybe Tracy can shed some light on this, running dual injectors, one set is 60lb and the other set is 120. Which would you run where and why?  The manifold was set up this way for the last project, straight up racing, just going to re purpose it here. Might as well.  I was thinking, run the 60s at the bottom and the 120s up top.  Thoughts?

I sure can, no prob.  Put all 16 injectors you currently have on Ebay, and buy on single set ( 8 ) of Bosch PN 0 280 158 821.  These are intended as Propane/CNG injectors but they work fine with E85.  You'll have no problem getting a smooth stable idle with them, you'll have even more flow capacity (20-30lbs-hr) than with the 16 mismatched ones you have now, you'll have a simpler fuel system with less parts and potential leaks, your tuning will be simplified (I am almost positive the Holley system doesn't have 2 separate voltage/latency tables for mismatched staged injectors and trust me the curves on the 2 sets you have are very different), on and on.  There is simply no reason to do what you're asking above.

[jax04]

I understand what your saying Tracy.  I have the setup i have because i had my intake modified for it, i was going to be doing things a bit different on the Mustang when i decided to scrap it.   The Holley knows the two sets of injectors, and they are actually built in options in a drop down menu, it was as simple as selecting them in their menu and it did the rest.

Now whether or not this changes your thoughts, im not sure.  I had the 120's idling perfect before, and the 60s have always been easy.  It does allow staged injection with two sets, high or low Z, or one set of each. First set is sequential and the second set is pair fired.  Which is why we did what we did.  The manifold already has 16 bungs welded in...  So you suggest i weld up the bungs i just had installed?


Zac, no the engine is not in yet...  LOL. Just got back home tonight about an hour ago.

[Speedfab]

Absolutely, yeah... Plug them.  Zero reason to do it like that.

[jax04]

Well, you tell it its parameters, and Holley sent the info for each to plug in.  The 120s are Holley LowZ injectors and the 60s are seimens.

If you are thinking it doesnt have separate voltage and off times, it does

[Speedfab]

That is the least important reason of those I listed not to do it.  Hell, a stupid ass Power FC will do that.  Just because you CAN, doesn't mean you SHOULD.

Remember that crash video where I was driving that 6 second Ecotec dragster?  That happened because one injector failed in a multiple injector (3 150s) per cylinder overcomplicated setup causing a single cylinder to lean out drastically, torch a huge hole in a really expensive head, destroy an engine, and wreck a really nice expensive car.  Learn from my stupid/painful/expensive mistake.  If injectors exist that are large enough to handle your application with one per cylinder, that is ALWAYS best.  If one fails, or your wiring harness does, it will just drop a cylinder instead of turning it into a blowtorch.

[jax04]

I appreciate the thoughts.  Let me ask you this then.   Being that the main reason this was done was not to be able to supply enough fuel, i can assure you of that.  You are 150% correct, their are many injectors out their that can handle the load i plan to run here.

The only reason we added injectors up the runner was for cooling and giving the fuel more time to atomize and pull heat.  We were planning to run a class where we got a break for being boosted and non intercooled. 

With that said, the 120s wouldve probably been sufficient for that particular class, and i really only did what i did for future thoughts, and we had tossed around the thoughts of dual fuel, methanol, etc.  So figured, what the hell, do it, if we dont want to in the end, then we can at the very least be a test dummy, test a set of injectors high up, vs. down low and see if their is any benefit with E85.

 I searched and searched for information on E85 (fuel injected) and what people have done with it, and the only person i came across that did anything that i could find and was willing to share info, was TJ Baker (63 impala, was running 6.90s non intercooled on E98) , and he thought it would be a great idea for a class that gave a break for non-ic, trying to give it more of a carb effect.  So we gave it a shot, and i really wanted to try it anyway.

I completely see your point, and i do appreciate your input, which is why i asked you for your thoughts.  Maybe dual is a little much for what im doing, i think im going to ateast try the difference between upper set and lower set and just move them down.
