He"ssssssssssss Back!

I just got back from a two day trip to Boise, Idaho to test the Hx-50 at 2700' and help kill 10 KDP's with the Idaho Rammers. The turbo worked as I expected, It spools real good and the dreaded EGT issues, were non existent! Averaged 78mph at 2100 RPM, 7-750*. Wot (bursts) 100-110 MPH, 1200*. Held boost to 54 psi. The turbo rocks for you low landers!!! This turbo loves fuel, recommend dd 111's or higher, fueling box for best performance.



This turbo is another break-through, much like Piers Hx-40.



Break-in, on any turbo, should be: pre-oil before running, don't boost over 20 psi for at least 200 miles... I waited almost 500 miles, and be sure to cool down before turning off. .



This turbo is an excellent up-grade for those that want to stay "single", if you have hit the HX-40 wall... Again, would not recommend for heavy towing.

P. S. You will have to watch "boost" as this turbo, presently is not wastegated. You could possibly blow inter-cooler hoses, and maybe worst, head-gaskets. i

Nether is the PDR Hx40 yet it blows away ( :-laf ) the PDR Hx35.

I have a hard time getting out of the boost above 50 psi with out barking the turbo. How hard is it on this turbo and is their anything I can do to help keep it from happening.



Max boost is around 53 or so. Box set to kill the hottest I can make it is 1170. Before above 1600 was possible with a stock 35 The only time I miss the 35 is in 2nd and 3rd gear.

If I order one you might be right, I may be "single" again for a while

Got an E-mail from Piers tonite telling me my SUPER HX-50/55 will be leaving the land northward heading my way



I'm PUMPED ok Turbo'd



Eat'M'Up has been seeming a little weak as of late.



A long with this Super Turbo I will also be getting some of those lazer cut delivery valves



SMOKE IS GOOD!!!!!!Oo. Oo.

 

[HeberRam]

It's on it's wayyyyyyyyyyyyy!

Dee... I see your'e turbo is comming! What exhaust housing will it have?



I don't know if the wastegate has been developed yet, but if it has you might be the first to try.



Steve

 

[HeberRam]

Turbo up-date!!!

Spoke to Al at Piers Diesel Research, today and the wastegates are in their final development stages. Hopefully, sometime next week, they will be ready for testing. . In addition, the larger exhaust housing is available. Piers, will offer the "New" modified HX-50 with either the 15. 8 cm or 17 cm exhaust housing, either wastegated or not in the near future. The wastegated models, will have a billet wastegate, mounted on the exhaust housings and can be adjusted for different settings at the turbo, or with a kit for in cab adjustment. . Can you say coooool!



Can't wait to get my hands on that puppy. Will keep you informed. Oo.



Steve

 

[drawson]

I don't know about the waste gate part but I am getting the 17CM2 housing



The big bummer is that Piers is out of delivery valve right now. But I'll have them soon:--)

Can somebody post the formula to convert kg/s to cfm?



Drawson, Have you got that HX50 on yet? I'm really interested in your opinion of the HX50 compared to the HX40? TIA

 

[drawson]

No Turbo Yet Hopefully the furst part of next week... .

Update

Thought I would up-date a little. The bugs have been worked out on the New HX-50 hybrid turbo, and Dee Rawson is one of the first with the larger 17cm housing, and is having excellent results at the 4700' elevation. See his tread:

Piers is still in the process of machining the external wastgates for the two different housings, and should be ready for testing in about two more weeks.



( hurry Piers, May Madness is only a little more than a month away!)



I can't wait to put the "squeeze" on it and Dyno. Oo.
