There are allot of folks on the TDR that are working on Twins, what about here.<br><br>Mine are great, I will not go back to a single!<br><br>

 

I am... but you already knew that.

 

Does in my dreams count? <br><br>I'll take donations,<br>I have 4 kids &amp; 1 on the way.

 

I take donations too. I have no kids but I'm paying for college does that count?<br>DM01

 

Hey Jim, I am working on a set of twins for my truck. I just joined the TDR and getting allot of good info there. <br><br><br>I noticed that most guys use the HBT3B (?) and the large turbo. The turbo of my choice is off a 3406C Cat. I just happened to get a couple for ;D free ;D. I can't seem to locate any info on this creater. It does not have any ID tags on it other than Cat. The way I figure it this turbo is used on the same displacement the HBT3B is. I know it is not wise to just guess with a turbo set up but the price is right. <br><br><br>Any Idea where I might be able to get any info on this LARGE turbo? <br><br><br>Thanks <br><br>Malcolm<br><br>AKA 24VChev

 

I will probibly have a twin turbo system by summers end. I plan on using my Piers Super HX-40 as my small turbo and a HBT3d that I just got as the large one. Before doing this I need to get my ported head o-ringed and on with studs.<br><br>I was just going to do NOS this spring but after seeing the Bully Dog 03 in action twins will be next then the NOS ;D 8)

MAC1<br><br>I just looked at your truck pics! I'm not sure were to get info about your big turbo, I run a PDR HT3B. When the pump comes off I'll send him the 35 also.<br><br>after seeing the Bully Dog 03 in action twins will be next<br><br>Did you see what there using as a wastegate, guess Mark and I have started a trend for folks to tryout!<br><br>Jim

 

I got a set on the cummins express

 

My post above is a direct reply from Al @ Piers, but wondering if that price is $US or $Can? Seems high if you think bout it. I am awaiting that reply as well?

 

I have a few sets on the drawing board, one for my truck and one for a 24 valve truck in town. Looks like we will have to go hybrid on all of the turbos to achieve our goals. Unfortunantly, this will increase the cost<br><br>Twins are not really a one size fits all deal.... especially with the 12 valvers. RPM range, manifold pressures you intend to run, fueling levels, how much lag can you tolerate, etc. <br><br>Don~<br><br>

 

I am not working on twins currently, but I already have the turbos. I am going to use an hx40 and a hx55. I have $275 in my hx40(new) and $500 in my hx55(new). Jeff Garmon said he would do the rest for $1200. So it looks like $2000 for me.

 

I am running a farmer-built stainless steel setup with a PDR HX40 with the 16 cm housing, huffing into box stock HX60 salvaged from a Cummins QST series engine. I am set to bypass exhaust at 93 lbs as measured at the top of the flat plate on the intake manifold at 3,356 rpm. I would have to change the 60 to a turbo with a smaller exhaust turbine for more pressure capacity to get any higher pressures. Although, I seldom run over 48-51 lbs unless I am locked to a dyno.<br><br>I do not think my drivetrain will handle much more, as every time I dyno now I have to replace the rear carrier bearings within a few weeks. I built the plumbing myself, so not much cost there, but the HX40 something on the order of about a grand and the 60 about $350 used, and I had to spring 5-6 hundred for the ATS exhaust manifold to handle the extra weight and heat.<br><br>Frankly, I cannot tell that much real world difference in normal driving over the single PDR HX40, unless I am pulling hard over the pass between Pendleton and LaGrande. Oregon just does not have any roads straight or steep enough to handle all the boost on a regular basis. <br><br>I have a problem with sustained pulling and engine oil temperature running way up to dangerous levels. I do not know if anyone else has that issue, or how they solve it. But, I am out of room to hang anything else on the truck so use Amsoil synthetic and live with it.
