How to lope???
 

Ok dont bash me too hard.... I'm building a truck for a buddy...1992 auto... He wants it to lope.... How can i do that????

Pinch-off one of the injector lines? :nope:

That might work...:argh: but no really... is the cam the only way??? I'm thinking in order to flow enough fuel we would prob have to get new banjo bolts where they connect to the injector as well as bigger feed lines that flow more.. I was just curious...

i would think that a little bigger fuel lines would do the trick. not to big though cuz our trucks dont move enough fuel to keep it running with really big ones. ive seen a site that has them. im probly gunna expierence a set of lines one step up from up from stock at some point soon cuz my lines are starting to leak and i dont think the next step up from stock ones cost much more. i havent really searched around too much though. i figure it cant hurt to much if i have to get new lines anyway. it might come in handy for a 14mm ve swap someday too

Oversized fuel lines will give you a little lope. ^

I want to say the site was PDR. I believe theyre about $400 a set w/o the clamps iirc. They do warn you that their largest size lines will ruin the trucks drivability on the street as falling to an idle will more than likely stall the truck. In the same token, to counteract the increased injection delay (the cause of the lope) timing will be one of your best friends.

a cam for the motor will not make a truck lope fyi...

^^This.

a cam ''can'' make it lope though..... right???? or cannot ever under any circumstance??? And i still can't find any lines guys...:scare2::s:

will not ever make it lope... ever. And honestly I've never heard of oversized lines for a VE since theres no use to go any larger with that style pump.

well PDP's site says they have them but who knows... Just thought we'd do something cool but guess everyone should do the same thing to their trucks and not do anything thats not ''useful'' huh??? :td:

Not to be slamming you friend, it's just that asking how to make a CTD lope is like asking how to make more smoke for the sake of blacking out the Sun.

Swapping an aggressive cam in a CTD, won't make it lope like swapping an aggressive cam in a BBC. ;)

People have tried and found it blows.

The thing with going too big with diesel injector lines is the fact that the larger lines are not as ridged as smaller lines. The larger lines are easier to balloon with the injection pressures and that ballooning, albeit subtle, effects the injection event characteristic timing. Makes it run weird and miss ("lope") at idle. This is not to be mistaken for tell-tail signs of a monster engine. :nope:

The 14mm VE H/R (never mind a stock 12mm) will never move enough fuel to see any advantage of larger injection lines. :pca1:

Ok..... so.... its an auto... with an h1c... intercooled...my list (for him) lol trans.. 1:good cheap hx 35 to hybrid or a hx 40.. 2:Injectors- who and where should i look?? Last time i searched around to buy some i had pretty much decided on some coaltrains 3: what in the eff are we gonna do about that trans???

also the larger lines also effects the timing of the motor as well since it takes longer for the fuel to get to the injector and builds the pop pressure slower as well. You can do what you want I'm just telling you when you buy a 500 dollar cam and it still idles smooth as glass your gonna be pissed :D

Well he just wanted it too lope... Its just a weekend toy... maybe get groceries sometimes... I'm just looking for answers... I just do what the customer asks... lol but i didn't honestly think he would like it if it could even be done... what do we do with that tranny.... build it???? swap manual?????

Build it or leave it, if he is only using it once in awhile and not beating the hell out of it then it should be fine. Not sure what mods he has done either.

sorry about that.. we're gonna run the trans till it breaks... it will have all the free mods.. timing power screw full throttle adjusted homemade pin..... straightpipe and either POD's or some 5x12's... KDP tabbed.. fresh upper gaskets and head... some porting on the ex. manifold... and eventually a turbo... studs too...

If he really wants lope tell him to get a gasser 1st Gen with a 360cid. Then stick a lumpy cam in it! It would be way easier and probably cheaper!

I was gonna keep this a secret, but i guess i will tell ya.:tttt:

i don't know how it will efect the IP but you could put a flasher in line with the FSS, put it on a toggle, when you are at idle turn on the lope switch,:yeah: when you want to go turn it off.:jump:

Dar:hellox:

Dont think this is going to work but if you want to make a mess trying it, more power to ya. If its not on the same timing as the pump it will just starve the pump of fuel randomly.

And put some oil in the gas for smoke!!!!:rocking::rocking:

I was being facetious. :argh:

I read in diesel power that project rust bucket lopes with the 14mm ve because of the custom ground cam plate. There's a vid about it on youtube you just can't hear it to well.

If he want's a lope, and a diesel, tell him to get an IDI and then set the idle at 300-400.

This entire thread should be deleted, stupidity agrevates me:argh:

Why is this??? because everyone should do the exact same thing to their trucks???? And ppl that want something different are automatically stupid??? Ignorance aggravates me.... make your own thread about how you don't like trucks that lope... or keep your mouth shut...:c:

So hows the build goin? Just tell him to tap his foot on the go pedal when he wants it to lope :D

On a more serious note, I've seen people do this.... :s:

there is so much you can do to those trucks with out gettin in the engin cams are not worth any thing and if your gonna build the engin build every thing else an engin aint worth jack didaly if you cant get it to the gound so go with a built tranny atleast befor you put a "cam" in it

well anyone who knows anything about diesels knows that lope is not desired and hard on stuff, ppl just need to do some research before talking about stuff like lope, you guys wouldnt last long on competition diesel:tttt:

Actually, a cam is very worthwhile in a performance diesel. It just won't make the engine lope. ;)

Please explain about it is not desired because if you read the FIRST post he is helping someone who WANTS it to lope. And what do you care it's not your money there wasting when stuff breaks. And no one said anything about competition diesel. How about if you ain't got anything nice to say then shut up.

I have been following the rusty project and have heard several other diesels with Lopes all from changing to bigger lines. So if he wants the lope go bigger lines. If he don't like it then change them back.

I'm pretty proud... I got the truck with a block, head, and 5 gallon bucket of parts and the guy tore it apart in his yard and is pretty much an idiot... but... cranked it for the 1st time for about 4 seconds and it fired up and purred like a kitten.. only problem i didn't catch was a bad o-ring on the sensor on fuel filter... the body work is done... still gotta do some pump tweaking and test drives... wish i would have taken pics but I'll try and get some finished products pics... painted the i/c tubes, intake horn, and valve covers to match the truck and that looks sweet!!!! totally recommend it... KDP tabbed... new front and rear mains on seal/gasket that wasn't replaced was the oil pan..

How could keeping your exhaust and intake valves open a little longer not be worth anything???? I believe that affects 2 of the 3 main components of a diesel... air and exhaust... i know they r basically the same but you know... anyways i totally agree with you on getting it to the ground too...

---AutoMerged DoublePost---

i had just never looked into it cause I've never had the desire to have mine lope but thats what he thought he wanted so i said i know just the place to ask....maybe if someday my truck gets far enough along that i think i need bigger fuel lines i might go with ones to make it lope a little....I just think it would be really hard to drive and really gay on an auto truck...

---AutoMerged DoublePost---

i'll agree with u on the 1st part for ''MOST'' people.. on a second note... who gives 2 sh!ts about comp d.. hence why i posted on here.... not there!!!!1:s:

ok so mabey i should keep comp diesel out of it lol, but i stand my ground on the lope subject, i aint got a dime in it and i dont care, i just get a laugh out of this whole thing

you can make a Diesel engine lope, it just isnt by wanting it too.

the reasoen why you hear a lope in a gas motor when it is at IDLE, the engine is starved for fuel.

A diesel engine should not ever lope, why, well if you starve your engine for fuel, it will cut off or by chance that it keeps running, you are not suppling enough fuel which inturns cause more wear on parts because diesel fuel is also used as a lube for your engine.

if you want your vehicle to lope, go by a gas motor , or by a power stroke, that is as close as you will get for a diesel engine to sound like it lopes, they are the only diesel that sounds like it has an unsteady idle.

just wanted to add, people who could not afford to upgrade the GAS MOTOR, they would turn there idle screw, this would cause fuel milage to go down. and people who knew anything about cars would know that there car is a fake, and would laugh.

this may be stupid but if you guys say that bigger lines causes the pop pressure to build slower, then wouldnt having a higher pop pressure give you the same result? get the injector cleaned and pop tested get them reset at a few bar ?10? above the factory spec. see what happens worse case is it doesnt lope but produces better atomization? and whats with all the negativity? innovation is key in the diesel word besides when people told rudolf diesel that you cant build an engine that is more powerful than a spark ignition and he listened then well we wouldnt have this site food for thought

---AutoMerged DoublePost---

i do know that if you put a copper washer in the number one delivery valve and not in any other cylinder it will cause one to lope until you just barely cracked the line so if you could find a washer or something to take up space in the line on 1 3 and 2 then it would lope kinda or maybe only three of the larger lines to give it a sorta lope

This is a good start but wouldn't that thow off your timing?? and then if you could even get it set right it wouldn't lope???? I don't really know.... just saying..

I think its gonna be one of those things you gonna have to try a few things and see what happens and how the truck reacts

I think i'll just make it run good and tell him you can't make it lope.. lol

Thats a good idea. :tu:

This is 100% false...
