Fuel upgrade?

[david-b]

So I'm kinda bored, so I came up with some question.

Ok, as most of you know I'm rebuilding a head and getting it ported and polished and cams, springs, everything... Would it be good for me to upgrade the fuel system at all? I figure I don't need a fuel pump, but would I benefit from any fuel upgrades? Fuel rail? Anything? Let me know.

On a side note I now work for Cingular Wireless making some fat hourly cash. I'm still in training, but once I get done with that I'll be making fat commission money ON TOP of the hourly. Should see some good progress going along then.

Unelss you can get more air in I dont think more fuel will do you any good.

no point in buring more fuel w/o air to make power out of it...

Yeah, wasted money IMO.

Cool. Thanks. Isn't the cams and the port going to add more air? Just not enough?

the ecu is more than capable of compensating for different airflow levels. If you look at a ecu map, you'll see what I mean. That's why if you tune your car at 11.5 at 16psi, then turn the boost up to 20psi, the afr will stay pretty close. I'm just guessing here about the nt stuff, but I would assume the ecu map works the same way. It sees air, then assigns fuel. Only a turbo is capable of changing airflow off the map

I'm not sure, but if your current A/F system isn't operating at capacity, I would see no point in a fuel upgrade. It would be like getting injectors and a pump, but still running a T-25... Once your airflow is great enough to starve the system by outrunning injectors and the pump, that's when you should think about fuel.

Sounds good. Thanks

...which is not to say people don't get what they don't need. On other novel ways to waste money on shit that's not really needed and is never going to be used to it's potential, contact Shpyder. He has an interesting resume` of that stuff
