Hey all, new to the H1 scene and so far a bit discouraged with my purchase. Bought a 2001 wagon with just over 18,000 miles on it, and already sunk another $4000 into it for minor things(nothing in the engine bay). Well, that may have to change quickly as it died on me twice today. Needless to say, I'm bummed. I've read about the PMD issue, and noticed it has an aftermarket PMD/relocation kit, but it's the set up where it's bolted to the top of the intake. It wasn't running super hot the last time it died, but I was in downtown Portland OR traffic, and it scared the crap out of me as there was no shoulder. Anyway, was wondering if anyone has had success with Predator products. Was considering a stage 3 kit as they claim it's about an additional 155 HP gain, with mildly increased cooling...anyone ever done a stage kit or had luck with Predator stuff OTHER than a Duramax upgrade?? Thanks!

 

I'd track down the current stalling problem before modifying it. First plan would be to have any codes pulled to see if there's a hint at where to start.

I have a 2002 7.3 Ford diesel that's been modified. I took the advice I was given so I'm just passing it on since it was solid information.

A diesel doesn't have a butterfly valve in the intake. It pulls in as much air as possible which provides cooling in the combustion chamber. The more you eliminate intake and exhaust restrictions, the more fuel your engine can withstand, thus more power. Basically, with diesels, you add fuel and get more power until something melts or breaks. Black smoke is wasted fuel which is fixed by improving airflow into and out of the engine.

I installed boost and EGT gauges first and looked at how my stock engine performed. It idles at about 350F, 700F on the highway and would max at 1200F. With a new intake system, new exhaust system and computer tuning the number went to 350F/600F/1000F. More power and lower temperature. Perfect.

My only concern with the Predator system is the use of a K&N Filter. It "may" flow more, under perfect conditions, but I've seen too many oil analyses with increased silicon using K&N filters (from ingested sand).

Regards

 

The 6.5TD has a limited capability for performance upgrades. Predator makes some great products but those horsepower claims don't seem realistic to me.

 

I have a 2001 also and had the exact same problem. I got a new PMD from accuratediesel.com and an extension cable and mounted by the washer fluid. Never had a problem since. I think it was about $300 with the cable. If you contact me directly I can give you my part number and send you a picture of how I mounted it.
