Anyone local with IDI for power comparison? - Diesel Forum

nosliw · 03-08-2005, 10:24 AM

I'm looking to see how my old IDI compares to another as far as power goes. I've never driven another IDI, but have driven other PSDs, 5.9 HOs, 5.9 12 valves, etc. and all would pretty much put me under the table. The only truck i've driven slower than mine was a 12 valve 5.9 automatic 3500 dually.

My truck just seems slow. My friend has a bone stock 96 PSD F250 identical to mine and he burns me up on the hills.

I guess I'm getting a little tired of messing with the old girl. Looking for something a little more "mod" friendly. I mean, after the turbo, is there much you can do to an old IDI to make her really "walk the dog"? Besides spending much $ on the engine? I'm almost afraid to add propane. I don't know if the engine will take it or not. It blows oil out every crack when pulling a good load. [img]/ubbthreads/images/graemlins/shrug.gif[/img]

Anyone local want to swing by the shop and drive my truck? You can't hurt it. The throttle is an on-off switch. [img]/ubbthreads/images/graemlins/biggrin.gif[/img]

A more simple thing to do might be to get a simple 0-60 time (a little tricky with a 5 speed but do the average of three good runs) and then compare it to the times people post here. Or it might even be easier to do a 40-60 run. Just a thought. P.S. I've been to Lexington several times. Very pretty down there! We used to haul Rocky Mountain horses to and from Olympia, KY. We have friends all around that area (I don't know of any with IDI's though).

Man, it sounds like you need a new IP. I know you said you already put a new one on there, but it sounds like it is pretty weak. With 4.10's and the 5 speed, you should be able to slay hills. You may not be able to blow doors off newer trucks, but you should really be able to make it run hard on the hills and have enough power. I know what you are saying about propane, I am paying for it now, but if you have the dough or the resources, throw some studs in and put the propane to it. IT is awesome. I am totally okay with doing the studs as long as I keep the propane. It was the missing link in the power chain. Scotty

i'm looking for some info about propane too can you help me out with this?

my truck is the one on the sign wath power increase should i expect?

the turbo is still far from my pocket but propane is cheaper and it also improves fuel economy not to mention sims much easier to install. wath about using it on the winter???

thank you, exekiel

sounds like you have something weak I've done a little stoplight to stoplight runs against my brothers 97 PSD and all he saw was the smoke from my stacks [img]/ubbthreads/images/graemlins/biggrin.gif[/img]

Not sure what kind of effects propane would have on a NA IDI, but I Am sure it would be pretty good. I would imagine on my set up that it is adding around 50hp and 100ftlbs, that is pure SWAG, but it is really strong with the propane on. Look into the Powershot 2000 and talk to Keith, he should be able to answer any questions you may have about the propane. Scotty

Conn, I would think if you got a modded IP and Injectors, your days of sucking smoke from a PSD would be over, I know you are not going to blow them off the road, but the trucks will really haul butt if they are getting all the fuel and air they want. Again, the propane is an awesome add on. Kind of similar to adding the turbo, I would really reccomend it if you are lacking in the power department. It was the missing link. Scotty

nosliw · 03-08-2005, 07:20 PM

man. i dunno. i just drove a worn out 95 12 valve cummins automatic that pulled like a MO-FO. and it was bone stock with 250k on the clock. [img]/ubbthreads/images/graemlins/shrug.gif[/img]

i like my truck, but dang.

i need someone else to drive this thing and tell me if there's something wrong with it i guess. when's the next IDI rally?

Gruss · 03-08-2005, 07:34 PM

NEXT IDI Weekend Thats about as close as you'll more than likely get. Hope to see you there(with the IDI) [img]/ubbthreads/images/graemlins/biggrin.gif[/img] Russ

I live in cincy, could meet you halfway maybe? Could only be like maybe a 45 minute trip each way for each of us (I live north of cincy). Or maybe hit up phillip kydiesel, believe he lives around lexington.

Yeah, if you drove an old STOCK 12V and it blew the doors off your truck, you have something wrong, a modded 12V should blow doors off ours, not a STOCKER. I think you are struggling with the IP or maybe just the timing is off, something is amiss, if you are that far behine, propane isn't what you are looking for. See if you can get it timed, run some Standadyne through it and then see where you are at, MAX out your fuel screw, and remind me again on what kind of exhaust and other intricates of your truck.. I think we should be able to find out where your power is at, because even if your truck is worn out, which it doesn't sound like, you might use alot of oil, but you should still have good power. Get your timing checked and then see where you are at. I will say one thing, Ken's IP really made my truck scream and it is just the turbo upgraded pump, so if you have any doubts about your IP and Injectors, and you know your engine still has some good life in it, a set injectors and the IP might be all you are missing.

I'll be passing by on I75 at the end of the month when we are going to and from Orlando. I'll bump ya a pm.

nosliw · 03-09-2005, 07:34 AM

cool. my shop is probably 3-4 miles off exit 115.

scotty, the exhaust was the 3 or 3.5" straight mandrel bent front hypermax until last week when i hacked it off and did my dual stacks. [img]/ubbthreads/images/graemlins/smokin.gif[/img] the pump screw won't turn up any more. (already had the cover off twice just to re-assure myself [img]/ubbthreads/images/graemlins/biggrin.gif[/img]) and i've got the hypermax turbo kit and a intake compariable to mel's. only not as good looking. boost is good. it will boost up to 11 psi or so before sucking the elbows shut on my air intake. [img]/ubbthreads/images/graemlins/phoney.gif[/img]

Don't know what's wrong with the old girl.

How do i check the timing on this sucker? I haven't found a diesel mechanic around here I trust well enough to touch my stuff, so I usually just figure everything out and do it myself.

Thanks guys.

this might be part of the problem you need a better flowing filter if its causing enough restriction to do that [img]/ubbthreads/images/graemlins/shrug.gif[/img] [img]/ubbthreads/images/graemlins/bleh.gif[/img]

it's a cone style K&N...is there anything better ?

agnem · 03-11-2005, 10:53 AM

What size? It's possible the elbow is bad. The rubber might be getting soft, or the shape of it might be changing. I run a K&N RD-1460 which is cyndrilical, and have no problems.
