0-60 times?

[Gary - K7GLD]

Curious as to 0-60 times for any first-genners who have timed their trucks - especially the AT trucks.

Been reading times for various brand trucks before/after various mods, most seem to run between 10-12 seconds with mods like chips, turbo housings, injectors, etc.

My truck with stuff listed below will show about 12 seconds 0-60 without propane, under 10 seconds WITH propane - wheelspin somewhat affects times when running WITH propane.

Still waiting to take truck out in the hills pulling our trailer up grades we frequently travel now that I have the propane setup installed, but wonder how my 0-60 times compare empty to other owners here?

Gary,

My setup is quite similar to yours (see sig) but I'm getting low 8s according to my G-tech Pro.

How do you like your Powershot 2000?

i hear you need a throdle position sensor

so the propane will shut off
one guy at MM said his would not shut off

any ideas ?

Wxman - sounds like your truck is doing real well. As far as my impressions of the PS 2000, that's a big reason for this thread, trying to figure how my setup compares in performance to other folks rigs. Apparently you don't have the propane on your truck, but are still into the 8's 0-60... HMMmm, makes me wonder about effectiveness of my propane installation, tho' other factors likely contribute substantially.

The accelleration runs I do are from a dead stop, NO "power braking", just mash the throttle and go, using the second hand on my watch and speedo for rough numbers. Obviously, if I was more aggressive in accelleration attempts, and had more accurate timing equipment, I might do better... or worse...

BUT, I have reached the point where I am spinning the wheels on takeoff, so not wanting to burn off too much rubber, and time spent spinning doesn't help times anyway. Biggest handicap in the "system" I use on my timed runs, is torque converter slippage, and the fact that the PS 2000 system relies on boost levels to apply propane incrementally. That's EXACTLY the way I want it to operate, since I bought the system primarily for towing loads up grades, and that puts the boost up where the PS system will operate nicely and be in full injection mode right when I want it. But when running empty, a quick stab on the pedal only creates a short burst of boost and propane injection, which quickly falls off as vehicle speed increases, and engine load DEcreases - so not a fair test of the system in a situation I really won't use much anyway - I'm not much for "stoplite wars"... Guys using the PS 2000 system and smaller turbo housings and wastegates that allow full boost longer and at low engine RPM will see MUCH better accelleration than I will with my stock turbo and housing.

I haven't had the truck and 5th wheel out yet with the PS setup installed - another week or so maybe, then I'll have a MUCH better idea of performance in EXACTLY the situation I bought it for! #ad


MOPARS, I don't quite understand what you are saying about "needing a throttle position sensor" - the PS system is activated by boost pressure supplied thru a line from the engine intake tract - the propane doesn't even START to flow until a preset boost pressure is reached - and THEN instantly shuts off as boost pressure falls back BELOW the set level. I've had no problem with mine - and unless someone screws around with the regulator pressure setting, they shouldn't have problems shutting propane flow off either. Defects CAN occur however, so maybe the owner should contact the manufacturer...

Gary - I do not have propane on my '89 Dodge/Cummins, but I do have the PS 2000 on my Jetta TDI (turbodiesel). I am considering adding it to my Dodge.

Have you tried experimenting with the boost onset adjustment? My Jetta is a 5 speed manual and adjusting the boost onset lower makes the RPM increase when shifting, which is an uncomfortable experience, because the propane continues to flow for a short time when the clutch is depressed. I wouldn't think that would be a problem with an auto transmission, however. Did your kit come with different sized orifices? Do you have any idea what size you are running now?

 

[Gary - K7GLD]

WXMAN - yes, I have my propane set to come on at a couple pounds boost - since I only plan to use it in pulling situations, it will normally be switched off at all other times, so the lower threshold is no problem.

I am using the . 136 "performance" jet. There's really little more I can do to the system to obtain any additional gains. There is NO sign of unusual motor noise or "pinging", and while under as much load as I am able to achieve empty under accelleration, switching the propane on/off DOES make a noticeable difference in performance, just not as radical in my case as some other enthusiastic users seem to be crowing about...

Let me be absolutely clear, I think the system is operating PERFECTLY, it's just that the mechanical setup of my truck, empty, does not permit the system to demonstrate the full capabilities it is capable of. I have NO doubt that a smaller turbo housing and wastegate, along with a "tighter" torque converter would make all the difference in the world due to boost running up at higher levels - and that NOTHING more I can do with the current setup will make any significant difference in observable performance. And that's OK, I didn't GET the propane system for drag racing, but for heavy pulling in the hills.

And you can BET that if it doesn't show substantial improvement THERE, as I expect it will, I will be a disappointed camper!

At stock, I would run 0 - 60 in 16 seconds flat. I have turned up the pump, running the 16 cm2 turbo, 3. 5 exhaust all the way with a dynomax muffler, 3. 54 gears, 285 X 75 X 16 tires and I have gotten about 12 seconds maybe a hair under that once or twice. I check timings the same as you with just a stop watch and speedo. I have a new transmission from DTT just waiting to install and hopefully that may bring times down even more. Mine is just starting to slip after 140,000 miles.
