COOLOo.





As usual

IN ROD WE TRUST

Rod,

We don't have a peak recommendation right now, but we are running it on a 500 HP+ truck, and EGTs with a Scotty II are well in hand. We're quite happy with the combo, and quite frankly, I don't believe there is a better turbo available for the single turbo crowd, especially if you're running a tight converter.



Now, some pics as I promised...



This first shot is a bearing comparison between the HX40, K. 45, and the B1. The HX40 is on the left, K. 45 in the middle, and B1 on the right.

And the shafts. As you can see, the HX40 and K. 45 are nearly identical, however the B1 is significantly larger. Again the HX40 is on the left.

The K. 45 and HX40 shafts look to be nearly identical, however the hubs are significantly different (HX40 on the left, K. 45 on the right):

Note the larger hub area where the wheel is friction welded to the shaft and the extra groove in the K. 45 hub. The extra groove slings oil and helps keep the heat from the turbine wheel from getting to the bearing. This reduces the issue of coking which also causes turbo failure.



Also look at the turbine blades and the support they have at the root area. (This is one of the secrets of the B-1's durability). In our opinion, the biggest reason HX40's fail is not from twisting of the shafts, but throwing blades. The moment a small piece of blade comes off then the wheel destroys the shaft instantly.



Last thing to note is the overall quality of machining/engineering. While the 40 should have been cleaned up better, you can still see some differences in manfacture.



Each turbo is available with a variety of turbine wheels and housings, we are able to custom tailor the turbo to individual and his truck. This flexbility and manufacturing quality, combined with the larger bearings (the outside of a bearing tends to absorb more vibration than the inside) are the primary reasons why I feel that K and B series of turbos are far and away the best ones for single turbo systems.

nice post rod. i love my b-1 it spools faster than my hx 40 did & i dont have to worry about it exploding at 50 pounds of boost. kurt.

 

[Agades]

Rod,

I have to say it



you really have your "poop in a group"



I think those pictures remove all doubt.



in my industry Ive learned that more metal in the right spots make all the difference in the world



great post!

Are the EGT's any lower on the K45 vs. a PDR40? What size exhaust housing in on it? How about the KSK45? Does it use the same downpipe as the HX40? How does spool-up compare to the PDR40? How about a ballpark price?

We have absolutely no direct comparisons against a PDR40. One of our plans is to stick a K. 45 (and quite likely a KSK. 45) on a customer's truck who is currently running a PDR40. Time is of course something that we're all lacking



The K. 45 uses a 14cm housing with a slightly larger turbine wheel than the KSK. 45 (which is a 12cm housing). The K. 45 is currently available with an EX3 housing (HX35 outlet), EX4 (HX40 outlet) and a B1 outlet (4" outlet), while the KSK. 45 is currently only available with a B1 outlet (4"), however Kurt is working on getting the EX4 housings as well.



EGT reductions? Pretty much pure conjecture at this point. We just don't have enough of them installed. I believe Kurt saw about 200F to 250F reduction on one of the 12 valves he installed on. We'll be getting more numbers after this weekend, when one of our dealers does a K. 45 install on fairly beefed up 24 valve. Same goes for spool-up. We have a good idea of how a KSB1B will spool on 24 valve trucks (quick. As good or better than a stock HX35/12). We'll be getting spoolup numbers on a B1B (very similar to a K. 45, only a heavier shaft) this weekend as well on my own personal truck.



As for cost, don't think I'm allowed to post that here.

How do I contact you for information

Rod,



I am a somewhat infrequent user on this site. How do I contact you to find out prices, results, etc.



Thanks,

Sorry for the delay. I lost my TDR account when they did that sweep and finally renewed yesterday.



I have been running the K45 14cm for 3-4weeks now. Previously I was running an HY35 that spooled perfect for my setup but we all know the limitations of it. Once I installed the K45 I noticed 200 or so drop in EGT's and a lot more top end. Spool up is a struggle because I am use to that HY 9cm housing. Problem is I run 37" tires with 3. 54 gears and have an ATS triple loc trans. That combo makes it tough to spool this thing up quick. So with my comp on 3X5 and up, I get lot's of smoke. Kurt is trying to get his hands on the smaller housing so I can give that a try and also his new external wastegate setup. Keep you all posted.

Everyone please keep in mind when Rod states the housings sizes as 12cm and 14cm these are just relative estimates. As far as I know only holset uses that system of sizing numbers. Most of the manufacturers use different sizing systems. Also a "12cm" housings will give different results on different turbos. Example a 16cm2 on a HX60 or a 16cm2 on a HX35 will react differently due to the turbine wheel size.



I prefer to keep the "Sizing system" that we use for the housings available for the B-1 and K45 Turbos as the "standard" housing and the "KwikSpool" versions. To be more specific the KS housing is 15% smaller than the standard housing. We do have various outlets available (In both sizes)as in the Ex3 (Hx35 &Hc1), Ex4 (Hx40) and B-1 (4") Style.



We now also have different turbine wheel sizes available for both Turbo lines IE: B-1 and K-45



I hope all of this is not too confusing. Call if you need a more specific answer to your questions.



It is nice that we can customize each turbo to meet the needs of the customer. Kurt

WUSSUP with the 45? Any new findings? I'll be needing a 40 or 45 SOON!

 

[Agades]

I really think this is a valuable thread for many of us and would like to see it continue



just got home from a 2700 mile pull and my compressor housing (stock HX 35) has turned from gray to dark brown



I pulled my 99 a lot harder than this truck and never discolored the compressor housing

whats the deal here?



I must do something as soon as I can afford to

 

[rweis]

I put a KSB1B on my 2002 ETC, see sig.



I will do the first RV pull in 2 weeks.



With stock injectors but a Scotty II, ATS manifold, KSB1B, Rip's 4" I could pull the 5er with better power. Same course as without the above would not hold 55, with held 55 easily.



Have added DD2's and a Comp (no VP wire). Have only pushed it once from 40 mph (8#) to wot, and it jumped to 85 mph and 32# in about 4 - 6 seconds. I have not had anyone follow me to see what smoke it puts out.



So far totally satisfied with the KSB1B. Make sure you know how to do the 4" exhaust before you order one though. I mis understood and it took me two downpipes and two flanges to get it right ($$$$).



The 5er will really tell the tale.

FYI, I plan on testing a Hx3512cm, then a K-45-4-ex3 and then a KSK-45-3-ex4 to see the Egt diff and spool up. With any luck I will also try to get a Hx40 (Maybe a KwikSpooled version) and a KSB-1 at the same time so that we can have comparisions of these turbos all on the same truck.



When? I hope two weeks

 

[BatMan01]

Kwikkurt

"When? I hope two weeks " Busy! Busy! Busy! It will be great to get some real comparison data. Thanks

 

[KWIKKURT]

Did I really say 2 weeks??? Another TypeO' I may have meant 22 weeks!

 

[Agades]

come on up to my place

we'll use my truck





I would come down there but have to stay around and keep business rollin (need money, putting up new welding shop)

Anything new with the K45?



KWIKKURT, did you ever get time to run the comparisons?



kbond, how is yours doing?



Justin H

 

[KWIKKURT]

Nothing new. We have been busy with several new additions to the B-1 Bomber line. Faster spooling versions for the Tight automatic trucks and the High Altitude trucks. Also a version special for the heavy towing guys and last but not least several new turbine wheels and exhaust housings for the Sled pullers and Big HP trucks that want to stay with a single charger. And most of the above can be used in a twin setup with the B-2 Bomber or "BIG BROTHER"





"Back to boostin"



Kurt

 

[rweis]

Kurt,



What do you do differently for the heavy towing?



I have a KSB1????
