This developed off the 500 hp thread, since this also may emcompass the oem turbo I didn t put it in hi perf, feel free to move it though if you think it should be. I made a comment about I did not perceive many turbos avalable for the ctd that I guess was wrong<br>. I have alot of experince with other turbo cars, buicks, twin turbo sbc's etc, even a turbo bike, and I havn't been able to desipher anything on ctd turbos? Im used to compressor maps, compressor wheel sizes, turbine housing sizes, compressor housing sizes, turbine trim wheel etc...and don t see anything in ctd turbo that seem to refer to anything particular?<br><br>hx 35 is oem right? If so....is the compressor map available? what ar ratio is it, what siae is the compressor and turbine etc.....<br><br>or list a bunch of numbers and get as close as possible with a discription...<br><br>hx 40? hx 50?<br><br>What are the others? How about the twins? what sizes are they using?<br><br>

 

1320 the stock turbo on your truck is a hx35x12cm &amp; there are more turbos out there than you can shake a stick at.I personaly am a fan of kurt yardleys turbos he makes several ranging in low to very high horsepower applications.You can get ahold of rod at wildcatdiesel &amp; he can explain all the differant turbos he has to offer or maybe they will chime in here &amp; let us know.(kurt are you out there)?I run one of kurts b1 standard housing turbos &amp; i can tell you they work &amp; are tougher than nails..hope this helps.kurt.ps these are some of kurts babys..

 

So what does the disignation mean?<br><br>hx? 35? 12 cm? I think I know that the 12cm is relative to the exhuast housing size? but in all other turbos its a ratio from the smallest point to the largest like .63, .82, .96, 1.20...???<br><br>What is the 35? just a number or relative to compressor wheel size?<br><br>

Hopefully this will give you a little more info on our turbo choices.

Turbo FAQ from www.dodgeram.org.

 

Good links, but so far it seems no one really knows what they are writing. A 12 cm exhuast housing? Well I can t find anything that defines what that measurement is? Apparently a 16 cm exhuast housing is bigger, but what is 4 cm bigger?<br><br>Anybody have some links to compressor maps of any oem or after market turbos like the hx40 or 50?<br><br>

 

When people talk about a 12 cm housing, they mean 12 square centimeters of area for the exhaust to pass through. More area means less restriction, but it also means that the turbine spins slower for a given volume of gas flowing through the turbo. That means that my H1C with the 21 square centimeter housing is turning really slow at a given exhaust flow compared to an HX35 with a 12 square centimeter housing, but the HX35 is causing more backpressure (unless the wastegate is open).

 

1320,<br><br>You need to get ahold of &quot;Diesel Freak&quot; he's been researching turbo's for a long while. He's not biased to any turbo (He does like his PDR '40 though) He has done alot of research, and is very knowledgable with A/R ratio's, Compressor MAPs and is just on the scene with turbo's. To the best of my knowledge he deosn't work for any &quot;high performance&quot; company, he just did research and put facts together.<br><br>I'm interested in what turbo's are out there also. The only people I know making reliable turbo's are PDR (Piers) and Kurt Yardley (Kwik Kurt).<br><br>Good Luck!<br><br>Merrick Cummings Jr

 

Pius also has turbo's I have no idea how to contact him though, hopefully someone else will post info about him

 

Here is the number Pius Bell Turbo PH. 1 209 467-8000 He has a new Switzer turbo modified for our trucks that is working out very well so well he has stopped the H2E's that he was building.<br>Bruce

If you are talking about the Switzer S-3..its a tough lil turbo. I have ran one with a larger compressor wheel. Its for sale and has 600 miles on it. PM for info.

Here is my latest monster. Its a HX55 with a 13cm non wastegated housing. It also will bolt up to a HX40 down pipe.
This thing spools like crazy for such a big charger. 8)
See turbo here!!

Nice picture J.R. Are you going to Virginia to see Joel?

 

Hey JR, if that didn't come from Piers or Kurt I would watch it...they're the only people that know how to build chargers....LMAO
