Pro Pulling League rules for 2013?

If I read the turbo rules correctly. Inlet side 2.605 that means most of the 2.6 turbos wont pass anymore by there rules. 2.650 was the rule. So everyone will have to change turbos again. Just something to look at.

That is what I have been thinking too. Just because a turbo passed at a ppl event in 2012 doesn't mean it can be assumed to pass in 2013. I was told recently of a 2.6 precision that the bore was measured at 2.64".

If I were buying a 2012 ppl legal 2.6 turbo I would want to measure the cover before I spent the money.
 
Seriously, what's the point of revising a rule 0.050"?

Like that's going to help anything; this is money spent for nothing.

Just one more way the sport continues to eat itself.
 
It was initially suppose to be 2.605 but was a misprint. Most of your other orgs like the tri states(OH,IN,KY) required a tighter enhancement so that's why it was changed to what the rule was actually suppose to state last year. A lot of trucks had a different cover that was ran at PPl events only.
 
They will put an angle finder on the drawbar and check it. Can not exceed 25 degrees. Still not sure why they put a limit on the angle.

So depending on how your truck sets in the neutral position on the scale is one angle however hooked to the sled can be another? got it :lolly:
 
That should be interesting because acoording to how it's written it's not the drawbar angle. It's actually from the pivot point to the hook point which may not be the same angle. Sure wish they would just draw a picture of what they want and be done with it.
 
Think about what a 90 degree angle would do to the force vectors being applied to the downward force versus the backward force compared to a 25 degree angle.

NTPA will use a straight edge to measure the angle not your drawbar.

Not gonna argue that, just pointing out another bs deal left to interpetation.
 
I dont have facebook. Can u have a dana 60 in 2.6? Or could we get a link for the rules.

That I understand but it will change going down the track, not much but it will change.

True. As your angle increases presumably due to the down force of the chain your hitch height will also be lowered. Theoretically the size of each direction of the vectors will remain constant.
 
Its really not that difficult. The degree from point A to point B can not exceed 25 degrees. If your hitch flexes its going to bend and loose height.

If my truck lays on my bump stops in the front & raises 4 or so inches under load the angle changes, not by much but more the the allowed spec. My hitch will not flex
Tested both tonight...lol
 
Doesn't matter going down the track. They are only wanting the 25 degrees with truck setting still. Besides if your truck lifts that much then don't have or set up right. This is the same rule as in the pro ally trucks so its been this way for years. So don't think it's something new.
