Pulling truck set up

[Nightlb7]

So if you had to set up a lb7 for Stock class and you had to set it up what all would you do? I'm talking anything hitch-tires-engine mods and so on, just trying to learn a little here

To what extent? 2.5 turbo rule? Does it have to be stock appearing?

 

[Nightlb7]

Yeah a few have been caught from what I understand, and it has to be stock as in no wheels nothing

At least what I have been told is no changes to the turbo are allowed other then wastegate

But can they tell if its ported/polished??

bfg all terrains, 60 over injectors and a modded pump. I would look into a hitch too, I have a bigchevyhitch, but its bending, maybe the new ones have more bracing? Otherwise I like it, lots of ppl run them. I would weld your front diff too (or get a locker) I wouldn't do anything to the turbo either. You'll eventually get caught

 

[Nightlb7]

True, roughly how much of a gain would that offer with porting and polishing? And yeah I have heard you move the hitch as far forward as you can get it and solid suspension stops

Like stated above, 60 overs, modded pump, front locker, and good tires. Sts seem to do good around md. I'm from md an pull there but they would be my tire of choice. Most guys running mapa have stuck chargers as the rules say.

What all do you do about the front end this is what I have heard lower to get the cv angles right, and take the torsion dampener pads out install a heavy bolt in its place and what about the hitch there is something more then just moving it forward?

First question - no.
Second question- absolutely.

Just porting/polishing the IHI with the stock compressor wheel I got 30 more horse power. I was surprised to see that much of an increase and how much faster it spooled.

How much was ported in the stock cover to achieve that power? Did you just basically smooth the inside to a slick finish or was there much more machine work involved? 30 horse is crazy

Look in his IHI Port & Polish thread.

I don't remove much on the cover, all the gains are in the exhaust housing.

That's awesome. Should be able to get over 600 horse with that. Would buy one if it wasnt such a pain to work on stock turbos lol
