I just bought a used procharger system that is about a year old. Everything is in good shape. It is going on an 02 f150 Boss. After I get the install instructions from Pro Charger, I am going to install the kit myself. I have a Diablo Predator Programmer and was wondering if anybody had any settings that I could put in my programmer to be able to drive the truck without blowing the motor. As of now I will be using the factory fuel system with the pro charger in line fuel pump. I do not want to get the truck tuned until spring because there are a couple of things I want to add to the truck that will change the tune. (Headers, 90mm MAF, possibly cam) Any help or feedback would be great. Thanks.

 

DO NOT RUN A BOOSTED MOTOR WITHOUT THE PROPER TUNE.... it will explode. not really but, you need a custom tune, find somebody good that tune with the diablo sport tuner, and make sure they have a good rep.

 

DO NOT run it on the stock injectors and MAF unless you runt eh FMU and even then you risk blowing your motor 'cause I'm sure you won't run 91 or better octane fuel

 

Actually I have been running 93 octane since I put the programmer on two years ago. It is not an everday truck. I am eventually going to upgrade the fuel system but there are other upgrades I would like to do first. The two main upgrades are headers and a full 3" exhaust. Right now I just have stock manifolds with a custom down pipe in which I eliminated all four stock cats and added two high flow cats.(Big sound and torque difference) I also have true dual 2 and half in exhaust from there on back. What would the fuel upgrades cost? MAF, injectors, fuel pump

 

you need a custom tune...

 

Like someone already stated if you're using an FMU and low levels of boost you'll probably be okay on fuel. I would think you need a low octane tune on your programmer which should have the least amount of timing, but run 91 octane at a minimum. However, you really need injectors of the proper sizing, a MAF that won't peg and a fuel pump that can provide the amount of fuel you need based on the amount of boost you need. You will need a custom tune to accommodate all that.

If you're thinking you can bolt on a supercharger and other bolt ons and not worry about these other issues, you're probably going to blow the engine. Which injectors, MAF and fuel pump you get is somewhat dependent on how much boost you intend to run. With modest boost levels you could find all three components for around $600, give or take. Custom tunes are somewhat dependent on who you use and whether they can use your Diablo.

 

Thanks for the info. I think I am going to bolt everything on for now but let the truck sit til spring. Definately do not want to blow the motor. As far as boost I am not sure how much I want yet. I am thinking 12-15, prolly 12 though. My one and only question is is why would pro charger put out a kit that is supposed to be bolt on that is pretty much a ticking time bomb if you run the set up they send with a truck that pretty much has the normal bolt ons that most trucks have? I did a lot of research before I decided to go with pro charger and pro charger seemed like a pretty reputible company. Sorry for being a pain in the a$$.

 

Most baseline kits use an FMU (fuel management unit), which is another fuel pressure regulator that increases fuel pressure under boost. I'm pretty sure you won't find a "kit" that uses one of these units that puts out more than 5-6 lbs. of boost. Using a FMU is not the most desirable way to tune. It'll work with moderate boost levels, but over-driving injectors beyond their design limits is not without problems. Doubling the amount of boost from these baseline kits and you need the right components with a custom tune.

12-15 lbs. is a lot of boost and probably beyond the design limits of the stock internal engine components. 10-12 lbs.would probably get you by with stock internals, but there are no guaranties that your engine will stay together. You're probably looking at a minimum of 42 - 50 lb. injectors and something like SCT's Big Air MAF with those goals. A 255 lph pump should get you enough fuel. The rest is up to a good tuner to make the package work.

With higher boost levels you're going to generate a lot of heat, so some sort of air to water intercooler might deserve your consideration.

Just one thought on camshafts. You probably don't want to spin one of these engines (5.4 - you don't state which you have) over 5,500 in stock trim under boost. The stock cam is good for around 5,200 rpm, so more lift can't hurt, but more duration is likely to extend the rpm range and make power at higher levels. If you want to do it right, get a built short block with a forged crank, good I-beam rods and forged pistons.

 

That answers a lot for me. Thanks. The motor is a 5.4 with 49,000 miles. Like I said it is pretty much just a weekend truck if that. I am glad there is a website like this that helps people like me. I never would have thought that the 5.4 internals would not be strong enough to handle 12 or more pounds of boost. My brother has a little civic hatch that puts down 500 to the wheels on 17 lbs. Granite his motor is done from top to bottom with nothing lacking. I think I am going to stay away from the cam. For now I will run all the stock Pro Charger settings until I get all the upgrades for the fuel system and the tune. I will probably have McNew's tune it.

 

I have been running the stock Pro-Charger set-up on my truck for a little better than 2 years. Run your stock tune with the FMU if you have it. It should have an intercooler and piping. The stock set up is a 8-9lb pulley and uses a "boost-a-pump"

If you don't have the FMU, you will need to upgrade your injectors to at least 39lbers and get a custom tune. If you were going through that much trouble, get a 90mm MAF, 255lph fuel pump, 12lb pulley and 42lb injectors and then get a custom tune. I am just waiting on my custom tune and programmer to arrive before I go this route, should be here before the end of the week.

Get a parts list and make sure you have everything before you start. It's a great overall kit that is easy to install.

 

Some can get away with 12 lbs. or more, some don't. A good tuner will increase your odds of getting away with it. I believe most people that push those limits tend to want to build a better bottom end if they do break something. But I can tell you 8 to 10 lbs. of boost in a 5,000 lb. truck is a hoot to drive and will be pretty darn reliable.

 

well you're not the average truck owner then, I ran my 2001 procharged truck on the FMU and 8# for a few months but it's nothing like the power and mileage of the tune and 15# though

you're going to need to help your transmission out and run cooler plugs at the very least, stock lightning/harley truck motorcraft spark plugs

 

Definately glad I joined this site. You guys are answersing all of my questions. I started to second guess myself with going with a pro charger. I got it for $1500 and it is only a year old. I think I may go ahead and order the 42#injectors and 90mm MAF from Ford Racing. I found them for $309. This is an off the wall question but how do you guys get the picture of your truck under your names when you post. I looked forever to do this. I guess i am just blind.

 

Only 12psi...you have to realize that 12psi. on these trucks will make in excess of 500hp at the crank. And pushing a truck over 5000lbs. at this level is nothing like pushing a little 2200lbs. honda. That's a lot of strain on internals.

And no offense, but I would seriously like to see the dyno sheets on your brothers civic. I've done a few nitrous, turbo and blowers in my day and have never seen a civic put down 500hp at the wheels at just 17psi. My friend Mark imported his motor straight from Japan in his blacked out civic and at 28psi. he is almost there granted the weather is cold. Although I do hear that a lot at the track and then see them trip the light at a 13 somthin'.

 

I will see if I can get the dyno sheets for you. Trust me, my brother is no bullsh---er. I took a rode in it and it is unbelievable. The motor is done from top to bottom, not leaving anything out. It took him 2 years to build the motor and about the price of a new car. You can see his car on you tube. Just type in candy apple hatch. Click on the picture with a mustang spraying nitrous out the front of the car.
