I have a 1993 f 350 7.3 non turbo,how can i get more air without breaking the bank. i am new and type slow

 

i cut off my soupbowl 1 hour ago

 

Click on my user name, Gallery, and have a look at my ram air scoop fabricated up with fiberglass. Album titled Lots of suck no blow, refering to great ram air system with no turbo- I'm very happy with the set up I have per my signature.

 

i like that,but not sure i'm very good at building things like that,give me a paint gun and i can do wonders.

 

will a better flowing air filter help?

 

just got truck,whats best way to set up exaust? Thanks for your help.

 

how do i turn up the injector pump,really don't know where it is.better flowing air filter heled alot,what other suggestions does any one have?

 

I wouldn't worry about messing with the fuel until you move the air thru the engine way more efficently first. Your truck is the same year /model as mine, so from my experiance, first thing, cut out the soup bowl, I always use a Ford air filter- its not cheap but if you look at it you can see that it has way more surface area, therefore more filtering area with less restriction than the aftermarket filters. If you can fabricate up some kind or ram air system to get rid of the Mickymouse restrictive OEM air inlet scoop you can get nothing but better air flow.

The next part of the equation, is if you have the OEM 2 1/2 inch exhaust, loose it.
At the very least, go to a local muffler shop and get a 3 inch pipe fabricated , including the Y right to the back. That will give you a dramatic increase in the responsiveness of the engine, quicker acceleration etc.

Actuall increase in pulling power, however, can only be achiecved by increasing the ammount of fuel you can safely burn. This will require the addition of a pyrometer.
I have increased to 4 inch exhaust, have a decient ram air system and headers. Only this has allowed me to increase the fuel to the point I am satisfied with the power produced, wihtout going to the expense of a turbo. Hope this helps and give you some idea's.

 

excuse me for being dumb what is a pyrometer,i've heard about them,what do they do? i want to get the extaust soon!should i get 4 inch true duels or 4 inch single pipe. are the headers real expensive.are they hard to put on?some guys say run straight pipes.whats the best way?forgive me for all the questions i'm new at this.i wish i could run a pipe to the bottom of the radiator support to get some really fresh air but there is no enough room,to much junk in the way. hey by the way do know where i can get some clear headlights mine are fogged up.thanks agian.

 

If your truck is not 4x4, the duals would be the easiest, 3" straight pipes would be more than enough even without headers. If you are going single, I would go for the 4". Headers are expensive, about $500 for the set, then a lot of fabricating to get a cross over pipe and Y set up together if running a single system. Pyrometer= EGT, exhaust gas temp. Mine is autometer, just drill and tap 1/8 hole in the top of the exhaust manifold right at #6 cylinder for the probe, easiest one to get at.

 

Kevin is steering you in the right direction.
You need more air before you need more fuel.

If you see any black smoke while working the engine, you already have more fuel than you have air to burn it.

 

I assume that when you speak of the soup bowl that it is the center of the factory air cleaner that looks like a funnel. It reduces the size of the bore from about 4 in to about 2.5 in????

 

Soup bowl

 

i have no black smoke at all and yes that is what i cut out on my air cleaner top.it seems to have a little more power.i'm going to keep on thinking about how to make my own ram air for my truck.i guess i need to get in my head that i can get only so much power out of a non turbo engine.i plan on getting new injectors,i think the original ones are in there still,i'm sure that will help.thank all of you for your help,i'll keep ya'll posted on my progress.if there is any more suggestions please let me know.

 

This is the route I took on my 86.
