Yet another "what turbo" thread

[jmd025]

Its not a laggy turbo buddy. And 300-325hp willl spool a 62 mm turbo. Where is this CANT SPOOL it info coming from? Also C-power....no hx35s came on 1st gens.

ok i did some research......mainly talkin to guys with first gens....... they said........ super 40 will work w/ pump turned up.....MIGHT be a bit laggy but not terrible....... but the 6 or 8 blade one would be more laggy.... had a few guys tell me the same thing.....hope this helps....

Awesome now we are starting to get somewhere... Maybe I might just learn something...


Now keep in mind that I am a complete noob when it comes to Diesel performance... The 300-350 number is indeed a hope, but I may have set my expectations too high....

Of the 3 goals I listed - driveability is key. I do not want to totally kill my mileage (and would really rather improve it). I want my wife to be able to drive the truck, without me having to worry that she is going to blow something up. The ability to tow is mandatory. I see no sense in having a truck that cannot be used as a truck. Surprising ricers (and 300+ WHP) is a hope... If I can do it without compromising on the other 2 goals, GREAT... If I can't, then I do not want 300+ hp .

Now with that in mind - Let me ask if my goals are realistic for a single turbo? If not, what is a realistic power level for me to shoot for? If it is not realistic, I would be interested in changing the direction of my build, with the intentions of adding twins (and more fuel) further down the road... However it is not in the budget right now....


As for injectors - I do not know. I have been reading alot and I know I do not want POD or marine 370s... I was thinking DDP stage 3 or 4, Bosch 190s, or Pure Diesel Power 120s (5x0.014) or a 5x0.012. I do not know what injectors would be appropriate with my goals (I am not sure if I like the $720 price tag on the DDP Stage 4s either). I do not mind smoke... but not all the time

You won't break an HX40 shaft with a VE pump, its been discussed before. Lots of overfueled P-pumpers are breaking the HX40's coming down from High rpm and 45psi....

And besides that the SUPER hx40 has an upgraded shaft.

I'd try to go towards a 65mm turbine or bigger...get away from the H1/hx5 60mm turbine...jump up to at least a 65mm

I think the S300 was a 57mm, but I am not sure...

How much USEABLE power can a H1C with the 14cm waste gated housing and 56 to 60 mm compressor support? What injectors would be appropriate for this turbo?

What about a 57mm S300?

PDR HX40?

Super HX40?


What is the HTB2?

By the sounds of it DDP 4 injectors would suit you well, it's just a matter of whether you want to fork the money for them.

If you can wait until later this week when I try to get my truck on a dyno I can tell you how much power I'm making with my DDP 4 injectors and he351 (rest of my mods are in my sig). My truck has a stock auto so whatever my numbers are, expect yours to be higher. I will say the truck has some berries. She's got some power, that's for sure. My fuel screw is still in the stock position too. I "think" I'm pretty close to 300hp. North of 250 for sure. We'll see though...

For the price I would not get the 57mm s300. For the same price you can get a super 40 and for air flow, that's about the best single you can buy that runs well on a first gen but it'll be about $1000-1100.

A PDR hx40 is a super 40 as far as I know.

57mm compressor is the s300G AKA the BD super B "single", AKA the HTBG, Its a little bit better than a hx35.

Hx40s are a good turbo, if you get the right configuration (there are many out there)....but there's no way I'd pay $1100 dollars for one. You can buy a 62/65/12 or 14 for less than that.

What is a 62/65/14? Is that a S300 also?

What are the measurements for the "right" HX40?

[jmd025]

S300 is a "frame size" for turbos...... a 62mm compressor s300 is actually called a s362.

62mm compressor/65mm turbine/14cm^3 exhaust housing.

As far as the hx40s go, it comes down to number of blades on the compressor....and I'm at a loss right now as to which option is the best... Hopefully someone will come along and help out..... I know you could get a 6, 7, or 8 blade compressor, and LOts of exhaust housing choices too.

7 blade hx40's are the latest and flow the best.

With an auto a 16 cm spools real good, go to a 14 for a stick.

BE SURE the turbine is a 4" outlet....Get a 4" DP and you're good to go.

WATCH the specs...There's a lot of '40s out there with 3" outlets. That's what you've got stock.

Excellent information guys!!!


Sounds like a Super 40 is the way for me to go...


Now, if I was going junkyard diving, what would I need to look for to find an OEM super 40 with a 16mm housing that would bolt up to my engine relatively easy? What is the going rate for a used one?

as far as I know, the liklihood of finding a real super 40 in a junkyard would be about as likely as winning the lottery. You might find a standard hx40 in a junkyard but as far as I know, you don't want one of those on your truck.

As for going rate for a used one. I don't really know, I'll throw a random guess out there at $500-800?

Well the truck just came off the dyno. With all the mods in my sig (stock setting with the fuel screw) and a completely stock auto tranny I'm putting down 251hp/562 tq. I can REALLY feel a lot of power being sapped by the auto. I wouldn't be surprised if with a manual truck with the same mods someone could put down 290-300, but of course that's just a guess.

ust reading through here again to see if I missed anything...

From what I have been reading the HX40 is only available with a 18 or 16cm housing... is there a 14 available also?? What about wastegates? Since I tow, I was thinking a 14 with a wastegate would be best, but does such an animal even exist?


EDIT - is there any reason I cannot use a "second gen" HX 40 on my truck? What kind of mods would be needed to do this?
