Hey everyone, I have a question when you look at torque plate power gain charts for the 7100 pump why is the manuel a different hp and torque rating? Its usually higher. Are the manuel and auto plates interchanging? Are the numbers accurate? Does anyone have hp and tq gains for a zero or 100 plate? THANKS ALOT

 

O one more thing I have a idea,I figured theres no difference just the reason they have a chart for the manuel and the auto is because the manuel puts more power to the ground? So an upgraded auto would put down ALOT MORE power to the ground. So the manuels are better at putting it down? THANKS

 

The reason for the different ratings is that the sticks made more power than the autos from the factory. I dont know if the injectors are different in say a 97 stick vs auto but there is differences in the pumps themselves. I cant tell you the differences as I am newbie to the diesel power world but I think that it has to do with the delivery valves and pump cams.

 

The pumps and injectors are different. The reason for the difference in HP though is the differences in the pumps and not so much the injectors.

Yes, all plates are interchangeable between pumps but some are not "preferred" plates in various pumps. The TST chart is a bit outdated now IMHO most do not really follow it anymore.

 

Correct you are..


the main differences for the pumps are the delivery valves, and the injectors, Hence one of the main reasons why they are called 180 HP pumps, and 215 Pumps and so forth. 215 injectors came off a 215 HP engine, with the 181 delivery valves, the 180 has 180 injectors, and smaller delivery valves as well.

You can buy out high performance injectors and delivery valves from various sources on the net, so all of that from TST is the reccommended, but not usually followed..

Zero plate and a 100 Plate (Pm northslope if u decide to get the 100 u wont be displeased) It is a night and day difference from either or in comparison to stock HOLY cow!!! that 0 willr oll the smoke on demand, I do not have any actual dyno numbers from stock, but i know that a 100 plate and a GSK, actually have the potential to give you 350 or so RWHP, with my zero i hit 376/902, but my truck had an intake, "banks" turbo, (riiighhht) banks 14 cm exhaust housing, the zero plate, stock injectors, and a BHAF that was actually borrowed he he he he, the zero is extremely agressive on fueling, i saw 1500 degrees POST TURBO if that tells you anything, and my clutch, and turbo were really screaming for mercy..

The 100 plate, I have one of Northslopes, and i perfer it to the 0 plate, its much easier on fuel delivery early on, less smoke, and holy cow hold on once ur turbo lights... but with a stock clutch, well.. u can only go so far..

Banks plate (see pic in my gallery) i estimate my hp with this plate full forward to be at about 315-330 rwhp, BUT my TQ is massive, i think im at about 800 or so, cause even with the banks plate i can outtow most chipped powerstrokes, and stock new rams quite easily.

yes plates are interchangable, and if ur gonna play, get some gauges to monitor everything first, then beef ur ur drivetrain and trans..

best of luck

180 pumps have the same 181 delivery valves as the 215 pumps.

There are several more significant differences between the pumps than just injectors and D-Vavles. That is why even if you put 215 injectors and a #10 plate on a 180 pump truck it still will not perform anywhere near the same as a 215 truck with a #10 plate.

 

What other differences are there in the pump? I would like to have a good idea of there design and function. Seems like most people dont understand the pumps inner workings to well. To relate it to a carb, it seems like everyone knows about jet changes but nothing about the air bleeds, squirters, or accelerater pump.

 

My bad, it was too early in the morning and yes you are right... sorry bout that, i guess i meant to say the 160 pump, but i wouldnt be surprised if that one has 180 DVs as well..... You learn from ur mistakes, i coulda sworn i read somewhere that they were different as well, thanks for correctin me!

Embarrased

Yep, 160 pumps and 175 pumps have D-Valves other than 181's found in the 180's and 215's.
