Engine/Transmission (1994 - 1998) pump camshaft ?

[JAmos]

Is there a pump camshaft that would have more power/performance than a 215 pump's camshaft? Is there a different camshaft for a marine engine (370)? Does anyone know cpl #'s to get a better cam than my 160 pump's shaft?

the 885 and 913 pumps have the best cam design for big POWER the 885 is actually a 180hp pump and the 913 is a 215.

Does that mean the cams are interchangable? I'm with JAmos, maybe my 160 has more potential than I thought...

 

[JAmos]

So is the shaft from a 215(913) our only choice? There aren't any bigger/better cams in different applications such as industrial or delivery trucks?



370's are marine injectors right? Does that engine have a bigger pump(370 pump)?



Basically the gist of my questions is does a higher hp p7100 exist(higher than 215)? And if so can we use the cpl or engine number to get a bigger/ better(bigger than 215) pump camshaft?



Thanks,



Jordan

Yeah, it's called a Stupid Pump. Call PDR for more info.

Actually, I believe it is spelled "Stoopid" pump, but yeah, that is probably the most powerful, most fueling P7100 out there..... well maybe not THE most, but pretty darn close.

The cams in either the 180 or 215 pumps are the same, the cut cams allow more fill time. I have run both in my pumps, at first I thought the cut cams were a source of my pump troubles and kept quiet about it, but now I know it wasn't. The trouble I had was running too much pump and not enough injector causing pre-mature cam wear. Cut cams are fine but to date have not made me anymore power. The cam in my stock pump is the same cam in my race pump, the only difference is the P&B's.

That is some very interesting info to know for someone trying to get more out of their pump.

Now I have heard this from a few people and also have heard the opposite about cut cams. What I have heard that in a truck pulling situation a cut cam for pulling will get you your fuel sooner and last longer. I know that my cut cam from piers looked nothing like my stocker did when it came back to me... I was amazed at how much was cut off! I also went with 13mm P&B's and its pushing quite a bit of fuel to say the least!

Yep, Piers ran those cams for the extra fill time no doubt as do the puller guys were they need it at there high RPM. I guess what I am saying is for a guys like me that never goes over 4k I haven't seen a gain in HP... . maybe it's just me. My best HP to date was with a mildly tuned 215 pump using 13mm P&B's but I do run on a dyno. We'll see what the future hold as I don't seem to be done yet for some reason.



So for something to think about here, lets play what if! Lets say a guy ran his fuel inlet pressure at 50 psi and made XXX power, then another guy ran his at 100 psi... . which pump would flow more fuel if built the same... ... . fill time/pressure... . hum!

That's quite a thought Jim! The only downside I can think of is premature wear to the pump inturnals due to the added pressure. Orifices maybe?



This sounds like a Grey area... . I like it!

[Jim Fulmer]

So here are your ideas to make it work correctly. Get rid of the overflow valve(I have) and run an external regulator that has a boost reference to add fuel pressure 1 to 1 to boost. There are a few ways to do this! 1. Tee in to the AFC so when your in valet you don't get the pressure rise. 2. Install a electric solinoid between the boost source and regulator so you can turn it on when needed. There there are several way to do this! You are correct on the pump wear, it will wash away stuff internally, that's why you want to control it..... just thoughts.

So cost wise, can any money be saved by buying a 215 cam, 13mm p&b's, delivery valves, and getting it all tuned together-versus buying a stoopid pump? Then with the extra fuel from this setup will it be too much fuel for 370's?



Doing these mods on a budget, which should come first, second, ect. ? The results will also be better having the pump tuned to each new mod right?



Jordan

 

[zstroken]

How much wear are we talking?? What is the stock LP putting out??

I've known about the stoopid pumps for quite a while now, I was looking for a pump in production that i could get a cpl or engine number for, pick out a good cam shaft, ect. , and build my own custom pump-maybe not as potent as a stoopid pump but hopefully cheaper.



Jordan

 

[Jim Fulmer]

Jordan, if you can get a 913, 887(5 speed) or 911(auto 180 hp) pump you can put 13mm's in it for allot cheaper. Call and talk to Brady@industrial injection about doing this, meaning if you can get a pump and send it to him. See what he will charge to do the P&B swap.



Jim

 

[zstroken]

I have a 911 pump I might trade for a 160 pump and some cash!!

I was going to point this out also about my setup. My pump is setup with 13mm P&B's, a cut piers Cam and a bunch of other internal mods and it turns 4500 RPMs at the current set up. When I put it on the truck I decided to just put in the stock plate for the emission test as well as the stock 215 injectors and stock DV's. Lets just say that mine pours out way more smoke with the stock injectors and plate than my brothers 215hp with a #100 and 370's and 191 DV's... its pretty crazzy! Can wait to see what my cut DV's, #100 plate, . 93 injection lines and my set of Haisley 5-18's injectors Oo. ... I think I am going to need larger twins!!!!!!!!! :--)



On a second not though for you... . I landed up spending just shy of what a PDR Stoopid pump is but when I got my parts for mine from the (days before Piers left) Piers told me a bunch of stuff to do it to make it keep up to one of there pumps and I am happy with the Flow #'s I got from it.
