and got rid of the loud valve train tick on number 6 or number 8 cyl. Idle has smoothed out and the 7.3 sounds allot better. Glad I did it.

Riffraff Diesel: Riffraff SS HPX 94-97

 

If they work that well, I may do one too! You can add it to your sig now

 

I did the hpx line and the 140 idm at the same time, and that smoothed out my idle a little bit.

 

I second that motion.

 

My HPX smoothed out my idle a little bit. It wasn't bad, but it was a little annoying.

 

Just make sure you watch the fittings. Some of them are known to blow out blowing 600-3,000 PSI of oil out under the hood.

 

True if you install incorrectly.

I've known of guys making their own and having that problem mostly.

 

I've got one on my truck and it smoothed out the engine quite nicely. Make sure you put new o-rings on it if you need to remove it for any reason.

 

Does this fit in a stock valley with all the stuff in there?

 

Yes it does

 

Is that from experience ?

 

When I get some other things done, I'm gonna put one on my truck. I'd like to smooth it out a little, especially at idle. It's got that "blat blat blat blat" idle.

 

Im glad im not the only one feeling that.it is not a miss just really an uneveness.next time i order i AM getting that! Thanks for the heads up!
Dang.i order any more frim riffraff i better send the wife some flowers or something.haha

 

Our trucks have a weak cylinder due to the oil pressure routing.

The only way to eliminate it is with HPX or dual HPOPs.

I really need one also.

I think I'll get one for the hell of it the next chance I have some buckaroonies.
