P-pump mods?

[98slushbox]

Has anyone ever had p-pump smaller than a 215 put on a stand and calibrated and not done B&P's? If so, was there much of a difference? Was wondering if it would be worth the time and money.

With no plate, GSK, and LC Delivery valves, they were able to get over 500 cc's out of a 160. . Then I went with a different setup. .

Did you just have it put on a stand and calibrated or (tuned)? There was no barrels and plungers or cam work done? I am running all the bolt on goodies in my pump now, but will be building a set of twins soon and was needing more fuel. Wondered if it would be worth trying? thanks Lance

98slushbox,



I just did my pump.



It put out almost 400 before they turned it up to 452. That was the max for my pump they said. I have 191 dv's, 3,000 springs. Oo.

The smoke it makes & temps to go along tells me I'm getting much more fuel now.

The proof will be at the Dyno. :--)

I sent my 911 pump in to Industrial Injection about a month or two ago to have it tweaked. They got almost 90cc's more out of it @ 3000 rpm. I notice a big difference, but i haven't been able to get on a dyno since then. I am going to try to catch up with Dunbar this weekend at Diesel Mania and see what kind of power its making now. I am glad i had the work done. No P & B's or cam work, just a tweaking

Do you know if they put it on a stand or what all they did to it?

98slushbox,



They put it on the flow bench to check the mods.

The fuel was turned up,

The pump, even with the 3,000 gov spring kit, still defueled to early.

NOW- it doesn't, :--)



The truck runs better & has the fuel to burn ! ! ! :-laf

Get this----- the fuel mileage improved

Mine gets better now than with the 180 pump that I had set up by a local. It has way more power now too.

My 175 pump I got in my truck now is set up for the same fuel the 215 pump I used to have in it. That was around 250 cc but the 215 pump had better power delivery. . . stronger down low, less smoke & better fuel economy. Sure miss it! I think the small pumps can make power but the drivability, EGTs & smoke control aren't as good as on the bigger pumps.
