Just a quick question about how to lower my EGT's, I am running the stock HX35 turbo and I think that I am pretty much at the top of its mapping range, I am getting about 32lbs of boost now and I can hit 1400 degrees with my box turned off if I stay on it for a period of time and with it on level 5 it just shoots right up there, and I was wondering would a HX35 Hybrid turbo be sufficient with my setup and is a Hybrid a stock HX35 with just a bigger housing or is there more to it? I am just looking at how to save some money if I can.Thanks Mike

 

From my experiance with Bombing CTD trucks - The real way to save money is to not be changing your upgrades over and over.<br><br>Example injectors: Almost 75% of my customers that have bought 275RV's or stage 1's end up changing them later to Stage 2's or Stage 3's. <br><br>And over half that start with the PE EZ upgrade to a PE Comp, Blue chip, or TST high power boxes.<br><br>Most of these are less than 1 year apart. So after shipping and Labor costs plus selling the old stuff as used for less there is a substancial waste of money.<br><br>This said It is the same with turbo's if not even more so.<br><br>I definately would not upgrade to a Hybrid 35 or even a bigger exhaust housing. Either a PDRHX40, or Diesel Dynamics 's Equal or a K45 or Y40 Hybrid as a Minimum if you are positive that you are staying with smaller injectors and light or little towing style driving.<br><br>Or One of the Faster spooling Bigger turbo's like a KSB-1 Bomber or a Hybrid 50/55<br><br>With the smaller one's like the 40's you will run the risk of still out growing their EGT's reduction if you are towing alot. But with most of todays fueling boxes you can usually turn them down or off for safe egt's while towing.<br><br>This size of turbo upgrade will usually cost you $300 to $500 less than the Bigger ones mentioned. And usually alittle less to install because of exhaust downpipe mods.<br><br>With the larger Turbos you will probably not out grow them unless you go Really Big injectors which would require Compounded Twin turbo system for Heavy towing. (Most of the time you would still use your already purchased Performance Turbo for the smaller Turbo in the twin setup.)<br><br>The draw back of starting out with some of the Big Turbos is they may need a Hot Box and Fairly BIG injectors for good low end response. (This is not true with all of them) Atleast one model spools good with near stock fueling.<br><br><br>To sum it up. Try not to do anything over later. You will save the most and be the happest with careful decisions. <br><br>In closing I want to say that most of my RV Towing, retired, Ranchers or Work Truck style customers stay with The RV275 or DD1's, EZ and a HX40 or K-45.<br><br>The younger crowd 25 - 50 Yr are the Stage2, 3 or maybe DD super, Don m's mach 2,3,4's injectors a Blue chip,TST or PE Comp box and a KSB-1, PDR 50/55 or equil.Turbo<br><br><br>And the Rest of the Power Hungry NUTS we all ready know what they want....<br><br><br>Hope this helps..

Sparky..great financial advise and information. For me, if I don't go through at least, 4 turbos, 5 sets of injectors, 2 injection pumps, 3 air intake systems, 1 exhaust systems, 2-sets of tires, rims, and other new cool accessories each year &quot;bombing&quot; wouldn't be much fun. <br><br>Steve

 

Thanks KwikKurt, Actually your K45 turbo was one of the ones that I was really leaning towards, so you do not think that this one will be big enough? I do pull 8-10 thousand pounds through the mountains quiet a bit whith a occasional heavy foot and like to do a little drag racing. I was under the impression that the B1 was more for the super modified trucks, would it be good for my application? The only other mods that I will most likely be doing besides the turbo is maybe propane.

I think you should give the HX35 hybrid some more consideration. I live just across the interstate from you in Longmont. I experienced some pretty substantial smoke problems with a PDR HX40 on my truck w/ DD1's - even w/ my comp box off. I found that the HX40 just didn't like to spool up here @ 5000 feet.<br><br>You can see a post I made on the TDR, give you some good detail: http://www.turbodieselregister.com/f...threadid=73092<br><br>I'm running the ATS HX35 hybrid turbo with their 10% EDM injectors (pretty close to the 20% extrude hone injectors power wise) currently, and LOVE it. With my comp off, I don't think I'm even hitting 1100 - and zero smoke. This setup is MUCH easier to drive, I am no longer constantly watching my side mirror to see how much smoke I'm blowing while accelerating. I think you may be disappointed with one of the bigger, slower spooling turbos.<br><br>If you like, I'll let you take my truck for a spin - let you see what you think. I'll send you a PMH w/ my cell #.

 

Will,<br>Do you tow with your current setup? How is it? Have you dynoed since the hx-35 hybred? I think that at our altitude, the bigger compressor housing gives us the higher pressure ratio we need to get the same boost pressure as guys at lower altitudes. As my truck sits now, I have to back off the throttle for temps while towing, and I want to add power/fuel, but I knwo I have to do something with the turbo first.<br>

 

The smoke problem that most have with the Hx40's is due to Lag. The KSB-1B spools faster than the Hx40's and you can tow plus you have less to worry about when adding propane and / or nitros. <br><br>As for the B-1's being for the more modified trucks. There are 1st gen's with stock injectors running B-1's and KSB-1's with great results.<br><br>If the HX40 size is definately enough Air for your intended power levels especially when towing then the K-45 is a good choice as they spool even faster that a KSB-1B. And they (K-45's) will take more punishment then most HX40's.<br>Kurt.<br>

I can not give you a great answer here.<br><br>However, I can tell you going up and over the divide on I-70 in Colorado will give any vehicle a serious workout. I've been on 7% grades pushing 100 mph with little temperature probs with my box on 1x5. Box off, I probably wouldn't hit 1200 degrees. <br><br>I actually just dyno'ed my truck for the first time this weekend. Box on 1x5 I hit 414hp, 834 ft-lbs. Not sure what happened, but on 5x5 I lost about 16 hp and 5 ft-lbs. Not sure what to make of that. I was unfortunately unable to make another run to see if it was bad run. <br><br>I agree with what Kurt said - the HX40 is slow to spool, especially getting to 10psi. Once at 10 psi, it spooled up fairly quick from there. However, my HX40 turbo never did ever &quot;catch-up&quot; with the fuel - It made as much, if not more smoke than my stock HX35. From what I hear, failure rate on the 40's are pretty high too - especially if you bark the turbo with any frequency. (can you tell I was not impressed w/ my 40?)
