Goto the Holset website and read a while. You can find efficency maps, service manuals and other intriguing things.

I've already 'killed' that site (my 1st visit... just got done... )..... in other words, I've read all the stuff and clicked on all the hyperlinks. I'll check back periodically for updates.

A VERY good site (IMHO)... . makes me feel like I really own a sweet turbo after seeing all their history and future goals.

Kat, Slang,



Thanks I think I am getting it. Just trying to learn. I will let this sink in. Not like I am going to get one anyway. My goal is to stay with in the 300-325 range with my 12v automatic. So my existing PDR Super Turbo, 14cm housing, 4" catback, Katless test pipe, and soon to be MoparGuy filter system is probably a good setup for me. Plenty enough airflow, boost, EGT control for my power level, and properly spools up my 91% DTT transmission. If I end up needing a little more I will have to spring for the 4" downpipe.

If thats all you are doing then the PDR turbo is the absolute best choice for you. However you might consider trying a 12cm² housing, not sure of your elevation where you are, but try the 12cm² housing and crank the boost to 35psi and I bet you'll like it even more.



Depending on what you use your truck for, the temps should be managable still.



What boost level do you run with your 14cm² housing?



Maybe Piers will add some "expert" comments here

PDR Trick Turbo

Kat, Piers told me the other day the 14 cm2 turbine housing reduces EGT by approximately 75 degrees F. (over its 12 cm2 counterpart). As I have a very tricked out Banks (Holset) 14 cm2 turbine housing (Big Head wastegate actuator set @ 38 psi), I will be retaining this piece when I add my PDR trick turbo (I'm meeting Piers on Saturday to pick it up).



Then, let the trick alterations begin!

Ya I know the housing lowers the temp, but a smaller housing lowers the lag! With DDIII's + EZ I couldn't get the temps over 1300° and even when it did go that high it would come down. That was with the stock airbox and paper filter as well.



If a 12cm² housing will work for the specific application I would gladly run it vs a 14cm² housing. I am waiting until my Hood is installed before I decide if I "need" to try a 14cm² housing, right now I can pull it to 1400° when in Level 5 on the COMP. I want to run the smallest housing I can so I have have the least amount of lag possible.



Prolly wanna lower the wastegate a bit down, Piers said only go 35 or 36psi, but you can ask him bout it when you see him.

Hey Kat, first off, I never really noticed any additional turbo lag after I installed my Banks 14 cm2 turbine housing (over the OE 12 cm2 one). In fact, neither did Rob Hanson or another NW BOMBer (both of which had the OE 12 cm2 housing). The only thing different between my installation and theirs was, I added the ATS exhaust manifold at the same time, porting and polishing the turbine housing and exhaust manifold, and having both ceramic coated (inside and out). Also, I discussed my wastegate actuator setting (WFO @ 38 psi) with Piers the other day... he stated that would be OK. I told him no problemo to reduce the setting to 35 or so, and he told me not to bother.



PS: NO EGT problem here (DD3s with a DD TTPM... among other things)

 

[Devildog]

I have a Kwikkurt's HX-40 in a 12cm2 housing, It pushes a hole lot more CFMs than my OE turbo ever did, Hence, I have a 4" exhaust and K&N air filter and with the OE turbo, the filter minder never moved this was with 42lbs boost. Now with the HX-40 12cm2 at 42lbs of boost the filter minder pulls down to 70%. Now I need to do something with my filter, maybe change to the Big Honking filter or such. If your serious about increasing boost you may want to give KwikKurt a call, cell # 602-525-5990. His turbo spools up real quick and my EGT are around 125 F degrees lower, The thing is awsome!

 

[SLang]

So is anyone running a non-wastegated HX-40 out there? Just curious.

 

[Diesel Freak]

SlyBones... . have you had a chance to look at that Floppy I gave you on sunday?





Anyone elso using the KwiK HX-40? I am really interested in this one.

Ya but you started with a bigger housing in the beginning, remember I started with a HY35 9cm² housing, so my definiton of lag and yours are prolly too different things But yes I may have to try a 14cm² housing here in the future, we'll see. Only time I have EGT problems is after cranking up the COMP to Level 4 or 5, which is usually only racing, everyday driving is Level 1 or 2. Floor It has an old Banks Housing, from like 1997 or something, I might try to pry it off of him to try it (its been out of the box twice lol)

Kat, I posted in your other racing thread that the 14 will make a small difference in your EGT's, especially with the Comp. For everyday driving, it doesn't change it to me enough that I'd want to put the 12 back on.

I can easily hit 36-37 psi, and the EGT's are around 75 degrees cooler. I really notice the cooldown times are quicker.

Yes I saw that Fred thanks, I am waiting until my AirBullDog hood is installed before I try anything, we'll see what the temps are like. The only reason I would try a 14cm² is because Floor It has one laying around

 

[EOliver]

Hey guys a quick question... I have a 93 W250, what is the model # for the turbo on my truck? I think I remeber a while back someone said it wasn't an HX-35... ? If it is not an HX-35 then is it similiar to one, and what kind of potential does it have?



I guess that was really more than one question... oh well.



Thanks!

9cm&sup2 housing? Good point Kat.

 

[HoleshotHolset]

I thought my 12cm HX35 spooled well... . I can't imagine a 9cm housing... . that's only 1cm bigger than the one I have on my minivan!

hey Swanson Man, were the **LL is Wadell, AZ?

Hey KatDiesel,



I was going to get the Bullydog air ram hood also, but from what I've found with the HX40, the stock airbox doesn't supply enough air! Maybe the Bullydog hood will force enough air to the airbox to make up the difference, but the stock airbox starves the HX40. The BHAF fixed it.
