hey guys i know this is not 100% relevant to this page but i didn't know where else to post it. I want to put a procharger d1sc on my chevy 2500 6.0. its all stock with a cat back exaust i want to run 6-8 pounds of boost and I'm going to get a custom tune right after i install it. My concerns are hurting my engine/transmission, worried about over heating problems I've heard about, how much boost can i run with the stock flex fuel injectors, would i be better off just to get a cam, heads, and LT headers and add 100HP or so. please help. i work with my truck and haul a trailer often. I've been told a lot that i shouldn't get a procharger but I'm pretty sure thats what I'm getting i want the top end hp and i don't want to be in boost all the time.

 

If you don't want to be in boost all of the time then I don't think a ProCharger is what you want.

The engine makes the most power at high rpms and when the charger is spinning fast enough to make boost.

So if you are pulling a trailer at 70 mph and your engine rpm is between 2500 ad 3000 rpm you won't be making enough boost to help much with either torque or horsepower.

For example ( perhaps comparing apples to oranges - car vs truck) but at 75mph my 1998 ProCharged D1SC is turning about 2100 rpms. At 2100 rpm's it's isn't making any boost so the charger isn't adding an hp. The charger adds hp only after the rpms rise enough to start making boost.

Looking at dyno graphs will show the same results. The engine starts to make boost as the rpms rise - linear. Yes the charger will add about 150 rwph but that's only at 6250 rpms. I don't think you will towing at 6250 rpms. More likely it will be below 3000 rpms

IMO adding a ProCharger for a power adder isn't going to give you the hp you want in the rpm range you run mostly when cruising or pulling a trailer.

IMO for towing you want a power adder that you will increase your rwhp between 2000 and 3000 rpms because that's where you need it when towing.

Ford 150's use turbo's to increase hp and torque for towing.

I think a Magnusson would be more appropriate for your application. Compare the chart at the rpm range your truck will be working. There's a big difference. You want torque over hp when towing.

Fools rush in where angels fear to tread. So with that in mind, because I have neither used a procharger or Magnuson supercharger, I think he is saying that he wants to avoid the extra heat of boost while towing so he wants to use a procharger. I am not advocating for the wisdom of that desire but that I think that is what he is saying. My understanding of pd displacement blowers is that they now have internal mechanisms that allow for no boost (therefore lower parasitic hp loss) depending on the throttle position.

BTW, I know how HP and torque are used to describe low and high rpm power but it does lead to some confusion when you do. Torque is the only thing that is measured and hp is a result of adding time and distance to that measurement. If you give a specific rpm like 2500, and say that boost is too low to help with either torque or hp, that is implying that one can effect the one without the other. It would be more correct to say that boost is too low to effect hp or too low to effect torque. At a given rpm and torque, there is only one resulting hp figure by definition. Conversely, at any given rpm and hp, there is only one torque figure. So instead of talking about torque, you could refer to low rpm hp.

Sorry. Too much time on my hands on a Sunday afternoon.

 

Prochargers work just fine for towing the 2-3k range isn't where you need globs of power. You downshift at that point. That range is where you sit on the freeway where you won't need as much power because you are simply maintaining speed. I'll go into more detail later but a prochaeger works well for towing.

 

How many miles can you get out of a procharger if you don't race/beat on it and just run low boost and use it for towing like the op? This is a durability/maintenance question. Same question for a Whipple if you happen to know.

That is what I was looking for. Thanks.

 

You're welcome. Thanks. Bob

 

Haha Bob steps in *waves* that's about all you will hear from me. Bob is probably more knowledgeable about prochargers than the people that build them.

 

Thanks, but not even close! Bob
