Can anyone tell me if there is a difference in the pumps internally? I know one comes off a motor that is rated at more power from the factory, but what about the internals of the pump. I am looking to buy a complete 12 valve to build to slip into my 2000, for a hot 2.5 truck.

I plan on sending the pump out to get banaced and maxed out, so is there any advantage to buying a 215 hp motor as compared to a 180 motor?
 
plungers in the 180 pump will move more fuel than the 215 pump. cam in the 215 pump will move more fuel than the 180. :hehe: if it were me id run the 180 pump. will most likely move more fuel overall than the 215 pump. IMO
 
I'm no pee-pump expert but, could a 215 cam be used in a 180 pump for even more fuel?
 
Yes, but the cost of changing it out would offset the purchase price of a 215 pump to part out vs. a new quick rate cam from many pump shops.

Also the 215 will retard fuel a high rack travels, vs. a 180 not.

Depends, the 215 and 180 share the same camshaft, though most 215's are going to have notched P&B's that will retard timing as the rack moves to full travel.

Some 215's dont have the notched P&B's and would be better fueling though their governor assembly is a little more touchy.

The 180 is more or less the way to go..
 
I have been around these motors and have gained quite a but of knowledge about them, but this will be my first hot rod build.
What is the power potential a maxed and balanced 180 pump? Can I get 600 to 750 out of it?

The governor assemblies and the barrel/plunger assemblies are different. Either one will be a good candidate for a performance build since they both use the "quick rate" Bosch cam (to re-emphasize what Taylor already said)

A 180hp pump can flow 375-400cc (depending on plunger wear) when maxed/balanced. A 215 can easily flow north of 500cc when maxed/balanced, but like others have said you have to deal with the dynamic timing retarding plungers (pulls out more timing as rack travel increases).

Either could easily do 600hp, 750hp is going to be stretching it for a 180 pump without large injectors and/or a dv upgrade. :Cheer:
 
Well it's funny that you should chime in on this. First, thanks a bunch. I take it you are Seth from DPE?

I know a guy that pulls around my area that refered me to you, to have pump work done. I was going to call you here in the next week or two before I went motor searching. To get your opinion on which motor to try and buy. I know this pump will not support my ultimate goals, but it will do for now. I plan on building this motor through the winter for next pulling season. If I could make any thing over 600 horse next spring, I would be happy. Its just a pulling truck and not daily driven, so I don't have to worry about drivability. Ultimately I would like a 1000 horse 2.6. But this being a 2.5 street class puller for now I think 600 to 750 will suit me just fine.

Seth, if you could PM me you number and maybe a quick quote as to what it may take to build this pump it would be greatly appreciated. Thanks!
 
180 or 215 will be fine. Seems like the helix may be better in the 215, but has the less than desirable retard notches. Both have a 903 cam. Which is much better than the one found in 160 pumps. On a Bosch test stand I have seen 160 at about 400cc's, 180 at high 400s low 500's and 215 at mid 500's.

Test stands are like dynos and flow benches when people compare over the internet.
 
You just found your pump guy too!

Finally going to try to look at getting a motor this weekend. Where can I find pump numbers to make certain I am getting the pump I want.

You'll want to look on the outside (driver's side) of the pump housing. If it has the throttle linkage bolted to the pump you will have to remove the three 10mm head bolts to get access to the bosch tag. 180hp pumps will be a 0 402 736 885 or 0 402 736 911 and 215hp pumps will be a 0 402 736 887 or 0 402 736 913
