I saw only 0.5-1.0 mpg increase. I didn't do a LOT of testing with them before I pulled them for another issue - but it was a pretty consistent test going home and back on a 4 hour trip.

i got me a set:thumbup2: brand new still in the blue plastic package in the yellow bosch box.traded a contractor out at work a puck for an 03 for them...he wanted it and i wanted the rv275's he just got it..so happens he has an 01 also.can't wait to get them in.:thumbup2:

98.5-2002 Dodge 24 Valve Cummins Bosch RV275HP Injectors

1998.5-2002 (24 Valve Only) Dodge Cummins 5.9L NEW 275hp 24 Valve Injectors.

Add up to 40HP to your 98.5-2002 Dodge Cummins Turbo Diesel!

Bosch Part Number: 432193635

Includes copper sealing washers & new o-rings for the injector connector tubes.

Set of 6 injectors, no core charge.

Increases the power by 50 horsepower and 100 lb-ft of torque at the ground on '98-'00 automatics. These same injectors add 33 horsepower and 66 lb-ft at the ground on manuals and '01 automatics. Throttle response and low-end acceleration are definitely improved with this addition. Fuel economy normally improves by 5% with this change. Injectors can be installed within about 3 hours by most do it yourself enthusiasts. These are new Bosch® injectors approved by Cummins® on their 275 hp 660-torque motorhome engines.

These injectors do not wash oil off cylinder walls and dribble at idle like some aftermarket injectors that are modified Bosch® injectors. Some 1998 24 Valve trucks need connector tubes with these injectors, these trucks have an engine serial number below 56462591.

THESE INJECTORS ARE ON A NATION-WIDE BACKORDER!

rv275's

what are the hp gains from these and would it benefit me to pull my 125's and install these. would i gain better mpg's with these compared to my current injectors???

ok so do you think the mpgs would get better running these as opposed to the 125s i have now

Anytime the tach needle pass the 2K mark you can garantee a loss of MPG instantly... Like for me to run 55-60 MPH I see 20-21 MPG everytime... But now to hit the interstat and run 75 MPH which now puts me at 2,200 RPM now I'm down to about 12-14 MPG... Funny... If I stay in 4th gear (1:1 ratio in the trans) and go 45 MPH which is roughly 1,900 RPM's I'm clearing over 25-28 MPG :stuned: But of course that's with 3.55 gears...:rolleyes: The other factor is going from 55 MPH to 65 MPH the wind drag nearly doubles... :wow:

That whole 2000+ RPM thing being instant drop is a bunch of crap. I know everyone preaches it on every forum but I have never seen an instant drop. I do 70 at 2100rpm and get 21mpg doing it. I got 17mpg pulling the trailer at 70 also. Speed kills MPG, not RPM.

That is a mystery I can't answer between the 2 trucks... :shrug: Like if I go down to Boise, ID and hit the interstate and drive speed limit everywhere I'll see roughly 16-17 MPG. But now if I avoid the interstate and use all smaller roads and keep my speed down (RPM related too) then MPG's natural rise for me... Now the only thing I could say that might give a clue tha P-pump's don't advance/retard timing but I know that VP44 do retard timing at high RPM's post-2-138698172314_thumb.png As you see for me running high up the RPM scale just retards timing... :rolleyes:

I've yet to see > 18mpg, ever, in my vp44 truck. My average DD mileage in the 24v is ~14-16mpg, all city. My p-pumped 12v (turned up) saw 18-20mpg in the same usage.

In my 12valve, from Virginia to Long Island, NY, we got 26.9mpg @ 68mph on the way there. On the way back, @ 72-73mph, I got 22mpg. empty, no trailer. My 24v gets ~17-18mph @ 65mph, empty, no trailer. 12v = #10 fuel plate - FF, AFC-FF, 40psi, 16.5*, 4" dp, catless/mufflerless 7" stack, bhaf, nv4500, 241hd, 3.55s, jake 24v = stock everything except bhaf, 5600, no muffler/resonator, 4" turndown behind cab.

What software is that map from??

I thought it looked like RR..Thats what I use for tuning Subarus..now, I'm gonna have to start digging a little ;) I've used RR since '07.

i believe it is the rpm's over mph.lets say 3 truck testing..going 65 or 70..this is for an example here...3.55 or 3.73 or 4.10..whatever.....automatic,5-speed,6speed.....and one of them has a gearvendor over/underdrive unit on it.....one truck at 70 is spinning 1900rpm....one is spinning 2100..one is spinning 1600 rpm..i would want the one that is spinning the fewer rpms..wouldnt you mopar??:thumbup2::smart:

have you gotten your injectors yet?:thumbup2:

I've yet to see > 18mpg, ever, in my vp44 truck. My average DD mileage in the 24v is ~14-16mpg, all city. My 24v gets ~17-18mph @ 65mph, empty, no trailer. 24v = stock everything except bhaf, 5600, no muffler/resonator, 4" turndown behind cab.

Funny - those figures are almost exactly the same as mine before I added my juice. Now ...... +1mpg towing (11-13mpg) ........ +1mpg city (15mpg-17mpg) ....... +3mpg highway (20-21mpg). When I add my RV275's back in {probbaly live with the stalling for now} ....... I expect around +1mpg extra to each of those figures.:woot:

Yeah kinda agree on this one. Interesting about the winddrag factor above 55mph (is that figure right mike ?) and the vp44 retartment with rpm. But I hit 20mpg on 65mph cruise control every time. I don't think I am going to see 24mpg running her at 55 mph ..... :shrug:
