Fuel System Upgrade


Recommended Posts

Now that I'm back in Louisville I've been hanging out at the local shop that used to modify all my cars. So we have been playing around with ideas on how to upgrade the SHO, and I have been sharing the hurdles we have been running into. With the major hurdle being the fuel system. He mentioned the issues that lots of people have with direct injection and the common solution that most use is adding injectors. So I've been having him explain to me how this works and what it would take to do it on the SHO. He's gona do some r&d this weekend but really feels that it can be done. Luckily he helped tune another SHO a few weeks back so he was almost certain we could change the pump or add an additional pump to feed this monster. Once that's done we can upgrade the turbos. He may be on to something here.

 

 

Any feedback or suggestions would be great. Turbo sizes?

2010 V6 Camaro guys with a DI motor are running into the same fueling issue when they try adding FI. It's not the low pressure pump in the tank that's the issue, it's the high pressure, mechanical pump that runs out of capacity. The Camaro guys basically can't get above 6 PSI safely. There is one shop that is working on a new intake manifold with injectors in the runners... but until then some guys are try methanol injection.

 

Not sure you could add another pump.... finding a new mechanical pump with more capacity will most likely be a challenge... The Camaro guys have been searching for a solution for close to 3 years now...

BAP definitely helps by making sure that DI pump always has adequate fuel to pump. The other aid is a pump that sprays Methanol & Water into the air stream just in front of the TB. Darreli is spraying 100% Methanol thru a #10 nozzle using the Alky Control system. I am spraying around 75% Methanol thru a #10 nozzle, up from a #7 nozzle & 50% Methanol last year. My system came From Torrie @ unleashed tuning. It begins spraying at 8 PSI & sprays at full volume until boost drops below 8 PSI.

 

There are rumors that Ford has parts # of a larger capacity DI pump that would bolt in, but so far it is just a rumor.

 

At some point, even with the possible availability of a larger DI pump, the existing fuel pump in the tank won't be large enough to supply it, even with a BAP. Then one will have to add a larger aftermarket pump and possibly larger lines.

 

Lots of other things to also consider.... turbo capacity, engine's internals, Tranny, AWD system, cooling etc....

 

At some point... just buy a new Escort and shoehorn in the EB 3.5!!!!!! ZOOM... ZOOM...ZOOM!!!!!

Ha! Now that would be pretty cool to see if someone did that EBB!

 

Your next project perhaps?

 

Greg, i've got nothing on this topic other than to agree with what's been posted here already by others.

 

Outside observations from both here, and other forums where this issue has been previously discussed, would lead me to believe that both EBB & Darrell are the most knowledgeable on this subject matter.

 

But now that i've posted here, I'm subscribed, so i'll be paying close attention to your future findings and posts about this, as well as others.

Interesting stuff, and great input from the guys in the know. My question is that with the improvement in the fuel delivery system with the w/m how much is the stock exhaust manifolds restricting the full performance of the improved fuel system? I was super surprised at the small diameter of the exhaust manifold and it seems this would affect the entire system.

There are so many other restrictions, such as the head restrictions, small turbos, etc, that until one changes all of them, ( which Livernois is doing), the exhaust manifolds likely work per Rick's comments on them. Definitely at some point, the ported heads, larger turbos, fuel mods and a beefed up bottom end, will require freer flowing exhaust manifolds. However, all of this will probably work best in the F-150, where the drive train after the engine.... won't need as much upgrading.
