Let's see, a 160hp pump vs. 215hp pump hmm... give me a minute my math skills aren't too good.

SuperiorRam

well I have read some and it seems that 160 could be built better than the 215 my quick math says duh 215 but want the better route

You can build a 160 pump to put out some fuel, it's been done many times.

There are 160 pumps that go like no tomorrow, but quick and easy is gonna be the 215 pump.

Just remember though. You will also be charged more for a 215 pump than a "weak" 160 HP pump. both pumps can be massaged to make tremendous power. If you are going for big numbers, you can spend less money buying the 160 version and then spend that savings with the pump builder.

BTW, my 160 HP auto laid down 309/751 at the rear wheels and has never been off the engine. Just a few simple parts is all it takes. I have a plate and timing as my only pump mods. Still has 131 DV's too!

well I could get the 215 complete engine with ata and boost tubes for 1600 as the guy selling it has no idea what he has if I were to do a change over from the rotary pump to online I could spend that much easy it's a 97 4x4 five speed that tells me it's a 215 from the little about the p-pump that I know it has 205k miles on it what y'all think? Thanks for all the quick answers I appreateate it

arnt they the same pump with different delivery valves and injectors? if youre worried about not having enough fuel put this into perspective. a 160 pump with laser cuts and 435's and enough air will put you over 700 hp when properly tuned. are you looking for more than that without nitrous?

SuperiorRam

this is the reason for this post I don't think that they are the same pump and in all reality if you don't know why would you tell me that some dvs and 435s and enough air will put down 700 I really don't belive that at all but I don't know jack crap myself so some one just tell everyone that one is so completly friggen diffrent than the other that they smell different or something I can tell ya that a 160 and a 215 rotary pump are IDENTICAL and some shops "tune" them better than joe shmoe and that not at all possibe now are they different like that and all the intrenal partnumbers are the same between the two or are they different in the aspect that if you had a 160 and a 215 and put the same delivery valves the same governer springs in the same fuel plate and had exactly the same amount of spring pressure on the afc which pump will do better? Or is one always up 55 stinkin hp? I'm just a complacted person and it seems like more than a simple math problem to me

The 215 pump has a better governor setup. The 215 is worth more if you were to sell it. Both of these P7100 pumps are inline pumps, not rotary.

Brad Ponci, from Ponci's Diesel in California has a 94 or 95 2wd truck with a stock 160 pump that has never been removed and "bench tuned" that has ran 11.31 in 1/4 mile which calcs to nearly 675 HP. Brad said the pump would make 700 HP if he turned it up all the way and ran stupid EGT's but dialed back just a smidge and perfectly tuned runs deep 11's all day long and the truck is used to tow trailers once in a while.

B Ponci is obviously an "expert" and not your typical backyard mechanic like you and me, but the 160 pumps can make big HP. That said, the 215 pumps are easier to make HP with due to cam profile, plunger design, delivery valve and holder size, etc.

I personally am not a P-pump expert, just sharing a few comments.

I was refering to the rotary pumps being the same thing but tuned diffrent to be called a160 or a 215

The 160, and 175 cam in the pump is different than the 180 and 215 pump cams. The cam isnt as agressive on the 160 and 175 pump as the 180 and 215 pumps. The 160 and 175 share the same cam, and the 180 and 215 pumps share the same cam. The plungers can be slightly different, but it is mainly the cam that accounts for the differences in how they run.

I believe with both pumps being pretty well maxed out... Laser cut DV's, 5k GSK, 2095 rack plug in the 160(not good in the 215, as it retards timing at high rack travel with a rack plug), and the AFC/plate the same, that the pumps will put out a very similar amount of fuel.

I can tell you that the 160/175 need a good fuel system to turn over 3200rpm with power, where the 180 and 215 trucks will crank 4k with the stock lift pump as long as the timing is decent. It is the way the cam is made. But once you have a fuel system on a 160/175 pump, they will crank up to 5k no problem.

Pretty much its just whichever pump you want/can get

Most pump guys I talk to like building a 180 pump with a 215 cam. the 215 cam has a faster rate but the 180 plungers are better they don't defuel. I got a 180 pump core pump and a 215 pump thats good so I'm going to take the two and make one good pump and one pump to sell.

I thought the 12 valvers were non complicated, this thread is making my head spin! 160, 215, 180, 175, plug this, dv that and don't forget the gsk. Makes me appreciate the plug and play nature of the 24 valvers. Sorry for the unnecessary reply but I couldn't resist. Eric
