i received my used powersshot 2000 and installed it the other day, ended up putting the forklift 7.9 gallon tank in the tool box of the truck, could not find a good location to mount underneath, installed the system in a few hours:ro)

so far everything is working good, could feel a real hit on a stock setting, have not tried to much with stacks, but as soon as things warm up a bit i will put on the dyno, for some numbers with stacks

has anyone played with the lp rate, the little small adjustment on the side of the powershot, when i called the company today(powershot, very very informative) she said turn it in all the way and then 3.5 turns back out, for stock settings, has anyone else treid any other settings with success, it was previously at 5 turns out, anyone else tried that, pros and cons, also any idea how long a tank will last at these settings, any other info a newbe should know, please do not be afraid, thanks fred:D

Fred, start at 3.5 and go up from there. 5 turns out should be about the maximum you would want to go. At 5 turns out, it is about 5- 5.5 cfm at 20 psi, based on a 5 psi start time. An 8 gallon tank would last about 1000-1200 miles of "constant" use, meaning it's on all the time, mixed, driving , towing , hot rodding;) etc. Remember because it is variable, unless you are at full boost, you are not using a great deal of propane, so it is pretty economical on propane consumption.

You've got my interest! Keep us updated.

It's all good stuff. I run at 5.5 turns out. I turned it up to about 12 turns once and got huge detonation. Your smoke with the stack will be really ugly. I mean, cut it with a knife thick. Street lights at night seem to go out too. You will love it. Looks like something that just jumped the fence from the local tractor pulls.

i will run at this, in a few days i might go higher, i know one thing, it is very smoth power, i have been told it makes less hp in a stack, but complements nos very well, so far so good

):h :D ):h :D ):h :D

Just what we wanted to hear :eek:

He's not kidding, whenever I get one of those pain in the butt people behind me, you know the ones that think two inches away from your bumper is ok driving behind you on the highway? Well I don't bother hitting my brakes anymore, I just turn everything on and floor it! It's funny the way they disappear, um I mean stop tailgating me.:D

My 100 gal propane tank lasts 2600 miles. I actually use a little more lp than diesel. I average 28 mpg on diesel, and 26 on lp. My best mileage thus far on diesel was 30, I got 950 miles on a 32 gal fillup.

if anyone else is intrested, i see two used systems(powershot and a ts system), for sale on the diesel stop fourm, for good prices, both come with tanks

Fredw,

Have you tried your cruise control yet...at the stock setting?

Thanks

if i remember right, you said you seen an improvement in hp with your big stacks, is that correct:ro)

I wish i got that kinda mileage :ro)

if i remember right, you said you seen an improvement in hp with your big stacks, is that correct:ro) Yes I do!:D

Is propane a set and forget thing or do you have to turn on and off a valve every time you start and stop the truck?

With my setup, I have a toggle switch under the dash that turns on the fuelock. This switch is fed from the ignition, so it turns off with the key anyway.

It works either way since it's activated by boost. You can leave the switch on and run it all the time or you can turn it on and off as you please.

i did that today, smooth as silk, no surging from what i could tell, and this at -25c
from what i can tell so far(whitout dyno resultsthat is) it feels like you can use a 130hp tune with lp to give you the same hp a 200 hp tune offers, :ro) giving you the better qualities and Charecteristics of the lower tune(less timing rattle, better fuel mileage)


with a 5lb start time, hoot, SD, or others, is this what you feel is the best boost to come on at(stock setting) or should one try to lower or increase

from what i can tell, when driving on hiway empty, my boost is around 3 to 6 lbs at 75mph, then pulling around 12 to 20, so just looking for the best results

thanks fred):h







Fredw,

Thanks

It's nice is'nt it? I'm only running the power pup on 80(for towing and winter) The big VA toggled off and the propane, unless it's too icey, man it's still goes fast and smooth. Exellent power and MPG.

hehe - amen Jim! Not only are they scr*wed for smoke, but they're left dazed and confused because they can't figure out how a big *ss truck can take off like that. I love my Dmax. :ro)

Fred, 5 PSI start is just fine. I have mine set to 8 or so PSI.

ok then i will leave my hands off, something to put in and forget about, thanks SD:D

just order the parts for the remote fill, will be nice when finshed, mounting will be side of toolbox:ro)

Fred,

Why

Fred,

Why did you choose the the system that you went with, powershot vs. the TS? Is one better than the other ? Or is it a matter of adjustments, quality, availability, etc...

i looked at a few when i started to look at propane, liked the pro 2000, and ts systems, but i seen more members here running the powershot, and when talking to them, they had sent me a ton of info, they also set me up with a used system that cost me less than half the price(paid 300 with tank),

i have been only running this over a few weeks, but one thing i sure see, is where i use to have turbo bark, (pulling or raceing) with lp turned on it is gone, as before it was bad, must be buring more of the fuel, causing less of a bark, this is a real good bonus with lp

I am interested as my dad has a 2002 duramax (LB7). what is the price? email me at aperry1@hotmail.com thanks adam

fred I added a guage to the black regulator it has a plug that can be removed. During the summer I ran the system pressure around 25psi to avoid the rattle as temps cooled off I could increase the the system to 35 or so............I found this much easier than adjusting the brass nut.................cant remember what the factory pressure setting was...............I bounced this theory off the experts at powershot they said what I was doing would work............changing the shot by varying the pressure instead of the flow......have not had time to install on the 04

that makes sense, powershot told me to set the primary regulator, or black one to 40 psi, so i can now see that working for you in the summer,(less flow), did not realise that lp made more noise in warmer temps, is this fuel related(#1 compared to #2)

Pressures in the tank can flucuate , more so with warm temperatures than cold. The tank pressure regulator for the most consistent performance, is factory set at 40psi. Sdaver is using tank pressures to manipulate the flow amounts as opposed to changing the settings on the unit.

How do you get that mileage? My truck see's 20 tops!

Add the lp and the diesel together, and you will see that I'm not really saving any money. All I'm doing is substituting lp for part of the diesel. It is nice not to have to buy diesel very often, and my lp lasts long enough that I never have to buy it out on the road, where it costs more than at home.

i just hit 800miles, and the tank gauge is showing 1/2 full, i have filled about 3 tanks of diesel so far, and two of the tanks have been pulling, powerstone do you feel that maybe my flow could be on the low side, thanks fred

Fred,

As long as you are getting good notciable power gains, and are happy.... if you can stretch 8 gallons of propane to 1600 miles, and you've towed with it as well, then I would think you have it dialed in optimum for your application.http://www.dieselplace.com/forum/images/smilies/rockon.gif You can always turn it up a bit or lower the start time, but I think right now you have it tuned for the best of all worlds.

Did you get a longer range out of those 3 diesel tanks as well? Meaning did you go farther on them than you normally would have?

will have to call you tommorow, did not see a big difference on the dyno, some flow settings might be wrong, call in the am, thanks fred

latest report was, the used regulator i bought was set for a start time of 14psi, and then it starts in a low variable rate, will send back for them to recalibrate, and test

my thanks goes out to powershot for great service in figure this out with me, thanks again guys and gals

it has been a week now without pane, and you can sure here the turbo barking bad, even more noticable when pulling, the pane must of burnt most of the fuel and prevented the bark, big difference:ro)

they are sending back after only being their one day, thanks powershot, as for the results, they found a bunch of teflon tape in the orfices i have been told(might be why the last guy got rid of it) as a good reminder, do not use teflon, pane breaks it down, and then all hell brakes loose, cannot wait to reinstall, turbo bark sucks

I know you have talked of pane lessing the bark.....when are you barking your turbo? Maybe its that the pane is still flowing after you stop injecting a ton of diesel(heavy defuel or lifting hard) and this is bringing the power down slower since you are still adding fuel???

could be very true, makes sense, not causing such a radical change, and thus prevent the bark, prob ally a Little better on turbo life as well, time will tell

finnally in and running once again thanks to powershot, hey and my bark is gone once again, did a few test runs and can definatly see a low end tq rise, in second gear any time you can grab rubber as before you were lucky to grab it, will do some playing once again at the dyno, keep you informed

Would the new tranny be playing a part in this as well?

In the bark or the cure?? Have you hooked up a trailer yet???;)
Think snow!!!:D

in second gear any time you can grab rubber as before you were lucky to grab it,

Thought the new tranny was playing a part in this.:confused: Or did i read it wrong?

curious as to why the propane would increase the smoke when stacking- any theories?

propane adds fuel.....if your adding fuel she's going to smoke more

Yes tranny work would help get the additional power to the ground for sure. I thought you were referring to turbo bark.:)

The idea is to use a "small" amount of propane so that it is burned completely along with more of the diesel. In an already overfueled vehicle, it could cause it to smoke more.;)

to keep you up to date, all has been working fine, even with a large 520hp stack, lp can be felt threw rpm scale, testing with the gtech it looks to add around the 40 to 60hp with the stock turbo, and makes the smoke very heavy, as for mileage the vote is still out with that one, will be doing some pulling soon and come up with some numbers
i can notice a slight timing advance with the lp, and no turbo bark, when its turned off the bark is back, works nice with wi on the westers tune, with the stack and wi it is almost to much timing, but strong numbers, the last dyno day i made in the low 600 with lp and wi working together(smokes even heaverier)
as for the tank, since i installed it, i can only get about 27liters in before liquid misting, bottle in upright will hold 33liters, not sure why the difference, tank so far could be bigger, might be to the led foot syndrome

done a few lp and n20 runs with westers and the stack, with a .090 jet and hang on, it almost grabed rubber at 50mph when it kicked in(with still excess smoke), without the lp made a noticable difference with just n20,(like almost 100hp less)
