I am going to goof around with the propane settings tomorrow. I am going to try and turn it down for propane earlier in the boost range, maybe around 2-3Lbs. I want to see how it works earlier on. Right now the way it is set, it really doesn't do too much until around 7-8PSI. I also wanna crawl around and make sure all the lines are fairing well with no running and stuff. I think it is going to be great once I get the IC stuffed in there. But first, I have to wash the old truck, I haven't got to clean it really good since it stopped raining in SoCal. Overall, I am pretty pleased with the system.

PS. Damn Banks boost gauge fell apart today, the darn glass just fell out of it, but since I am still under warranty, they are sending me a new gauge. Scotty

That's great you got it in. Are you going to try to dyno it twice with it on and off or just going for the gusto [img]/ubbthreads/images/graemlins/grin.gif[/img] [img]/ubbthreads/images/graemlins/grin.gif[/img].Hope to see you there on the dyno.

I plan on running it with propane off then with propane on. Hopefully I will see some kind of worthwhile improvement. I sure hope so, since I paid so much for the kit. But, I can't see it providing less than 75Ftlbs, I am pretty sure that will be a fairly easy number to accomplish. I am hoping for something around 550Ftlbs or more. I know this seems kinda reserved, but I would be totally happy with those kind of numbers. Scotty

Scotty, congrats on the cool mod. Do you have propane and water now, or just the propane? What's your timing set at? Any knocking? Yes, pictures of course. [img]/ubbthreads/images/graemlins/wink.gif[/img]

beretzs · 03-01-2005, 01:09 PM

AS of right now, I only have propane and next will be tackling the IC project, bringing up the rear will be H20. My timing is set at 6.5*BTDC. I had it retarded 2* when I had the truck timed after I installed the new IP and Injectors. The H20 Inj is on the last to do list, simply because I want to figure out a good water tank set up. I am hoping to do something similar to yours, but haven't had the time to get that together and I really want the IC in there. Scotty

psychostroker · 03-01-2005, 06:18 PM

If you were closer I'd offer to put that truck on the rollers when you're done with the projects to see what she'll do [img]/ubbthreads/images/graemlins/smile.gif[/img]

1st run with just the IC, then do a run with the LPG on, then run with the H2O injection, then..... Crank everything up and let her rip!!! BWAAAHAHAHAHA!!!! [img]/ubbthreads/images/graemlins/grin.gif[/img]

Alright, this has been a good day, I wanted to mess around with the settings on the system, because I wasn't really feeling too much in the way of power, and after the other stories of other guys saying they can feel the propane, I thought maybe something was wrong. So I called Keith at PowerShot and he walked me through my set up and wham, I had the LPG hooked up wrong. I had it hooked into the intake chamber. Well, little did I know, it has to be pumped into the intake, BEFORE the turbo, so I drilled and tapped another hole. Plumbed it up, and drove and WOW oh WOW. You guys have no idea what you are missing. I know you guys are sick of the "seat of the pants" saying, but I would say, once mine hits at 3lbs, which is was factory set for (asked Keith when I was on the phone with him today) I thought it was higher in the boost range. But when you hit 3lbs, it just pretty much climbs to 10psi FAST. It is like getting a huge tailwind and throwin the truck forward. It is awesome. Now the bad news, If I push it past 7psi, it starts hammering, not really hard, but enough to make me back out of after a few seconds. I did a few runs with it up some more hills, but due to the hammering, I backed out. So, as it stands tomorrow, I will keep reatrding the timing until I get it right.

I am not sure how much light hammering is acceptable, so I want to minimize it, (PS, Ken if you are there, please chime in). I will back it off a 1/16 or so until it clears up. I know I will lose some of my bottom end, but with 4.56's and the turbo, I don't really have much trouble getting rolling. So you timing and propane guys, chime in and let me know the best way to skin this beast. Man, if I can get this run hammer free all the way through the boost range, it will be a force to be reckoned with, I think it really takes the trucks to a whole new level.

I was getting some propane before, just really not a whole lot, which does say something, it was still helping, but just not near what it could have. Now it is plumbed in correctly, it is AWESOME. Well, hopefully the dyno will show me what kind of difference we can expect, but I would say an easy 75ftlbs now and probably more along the lines of 100-150Ftlbs. Well, hope to hear from you guys tomorrow, since I will go to work in the morning and scam out and try to start the IP timing. Shouldn't be too bad.. Scotty

Why'dya have to go and do that? I just ordered my wife a new computer (refurb) for school.

I coulda spent a little more and had propane... :-)

One note... I really MUST turn up my pump. I saw an older Ford diesel in traffic today. Gunned it from a slow roll to get off the packed/traffic jammed interstate and merge onto the exit ramp. Just took off like a jet, rolling black smoke all the way.

I gotta do that to my truck!! [img]/ubbthreads/images/graemlins/smile.gif[/img]

Huff · 03-02-2005, 01:28 AM

I would recomend the timming at 4deg BTDC at 1400 rpm warm (pulse method) the big problem is your LPG flow rate is a smige too high, loosen the jamb nut on the small slotted stud, reduce the setting 1/2 turn, (printed on the unit) then work your way back up 1/8th turn at a time. If you here any heavy combustion noise, back it off a 1/4 turn and set the jamb nut, your done.

beretzs · 03-02-2005, 09:42 AM

I am already set to 6.5BTDC, so I am going to adjust the flow rate. Talked to PowerShot folks this morning, and they gace the same scoop as you Huff. Thanks a million, the truck runs great, I will start backing it off a 1/4 at a time and work it from there. I cannot wait to see how it acts once I can get through the whole boost range without hammering. Scotty

PS. Did I say how awesome this stuff is, never did drugs, but man, the truck really likes em.... Scotty

beretzs · 03-02-2005, 04:12 PM

I thought I had it, but by the time I was halfway home I was blowing coolant and it was still hammering (very slight) at upper boost and RPM ranges. I already backed it off about a 1/2 turn, and want to wait for the turck to cool down so I can see how much coolant I lost. Pretty minor stuff in the whole scheme of things. Hopefully by this weekend I will have it tuned enough to run on a dyno. If backing it off the 1/2 turn doesn't help, I will look at backing off the timing incremently and see what happens. Anyhow, I will continue with the messing until it is straight. The power is really there. Again, for you guys that need that little extra, propane is probably the easiest and cheapest way to go, because you can use it when you want and if you don't need it, don't turn it on. Scotty

psychostroker · 03-02-2005, 04:56 PM

Were you blowing coolant out of the radiator cap?? I hate to say it, but if so, that's not a good sign. [img]/ubbthreads/images/graemlins/eek.gif[/img]

aaklingler · 03-02-2005, 05:38 PM

Ken, its a good sign for you, he'll be padding your wallet when he buys a set of head studs. [img]/ubbthreads/images/graemlins/smokin.gif[/img]

beretzs · 03-02-2005, 06:32 PM

Both you too, simmer down, there seems to be no ill effects, no coolant in oil and no oil in coolant. Everything seems to be good (cross your fingers) but I was not blowing anitfreeze out of the cap just overflowed my overflow jug. I turned it back again and drove it up about 20 miles over hills and stuff and no coolant when I got there, no white AF smellin smoke, naddaa. I was kinda worried at first also, I "think" (this is not even an educated think) the propane was advancing the timing too much. Since I have backed it off, it has been good. I just checked the oil and AF again, and nothin, so pray to the diesel gods for a good outcoome to this. Anyhow, thanks for the moral support. MAN, oh well, how does the old saying go, "you have to break a few eggs to make an IDI" well something like that.. Scotty

aaklingler · 03-02-2005, 09:08 PM

i hope you don't have to write a check out to Ken until your good and ready, but it didn't sound good, what for egts and water temps were you seeing, how much power have you lost now that you turned the propane back, try ajusting the timing and see if you can turn the propane back up.
