Opinions on HPX

[YJSONLY]

Is this a worth while mod? Or what is the benefit from it?

Not on the OBS no. SD w/ the deadhead, yes.

Think you might be confusing this with frx, bot the obs and sd can benefit from an hpx as i understand it, allows for oil to be at the same pressure on each head.

Yep, I sure did confuse them. Thanks for the correction. I'd say the hpx can be beneficial... never a downside for equalized oil. But I prob wouldn't waste my money on it until higher up in the HP range.

I dont see it really being benificial honestly...

 

[always-strokin]

Thats why I said higher in the HP range. For 500+hp, I can see the small things such as frx/hpx being beneficial. For a stock or lightly modded motor, I doubt it does a darn thing.

another place to leak too! The info that i have found on it is its hit or miss, some people swear it makes their idle so much better, others don't notice a difference.
Frx is a different story in the superdutys though, definately beneficial even on a stock motor.

Meh... I COULD be wrong, but am quite certain none of the higher h.p. 7.3's have them. Not to mention, its gonna make working on your motor a bigger pain in the ass if you need to change the ipr, any harnesses in the valley, and maybe the fuel filter etc...

Just pull the fittings from the HPOP and remove the check valves. They look like small springs with a little plate made onto the end. When the spring portion breaks it reverses the direction it works and cuts one head off

I put an hpx on mine, smoothed out the idle and made it a touch quieter. No issues in the 5000 miles I have had it on.
