What is it that makes truck loap or hunt? How would one go about making one do it?

 

You want your truck to loap? Or you want to fix it from loaping?

 

Let's make it loap.

 

Are you talking about like a SBC with to big of a cam and big exhaust and way over carburated, sound.
There are many ways to make it sound like it's a ****** off truck but most all of them would be bad for the engine and would do nothing but hurt performance.
I guess I'm not understanding what you are wanting to achive by this. A little more explantion would be needed.

 

I think he wants to make it sound like a hot P-Thumper, with the whump whump whump sound

On a p-pump that is done with governor spring bounce and lots and lots of timing

Is the lope at the beginning of this video what your talkin about

Yeah, thats what I'm wondering about

 

My truck isn't very hopped up and it kinda lopes in drive at a standstill

 

Too big (ID) a set of injector high pressure lines will do it.

 

like this? http://www.youtube.com/watch?v=wpGWqG6RwuM

I think it makes it sound sweet, but idk the reasoning behind it.

 

my dads roll back sounded like that... but thats cause the fuel pump went bad

 

could just sit there and fan the gas pedal...lol

 

on a diesel forum, there are no gas pedals, same thing with gas mileage, its the diesel pedal and diesel mileage

 

throttle pedal works too. I have found that gas is not in my vocabulary (correct me if i say it) but I always say "fuel" even if we are talking about a dirt bike. lol. When my mom tells me that I waste "gas" I tell her that my four-wheeler hasn't moved in several months.

 

exactly,
