    Holsets and BPs?

    I have recently looked into Holset HY35's and have seen 1 guy on miataturbo.net that has a Holset on his miata, has anybody on here done such turbo in their kit?

    What kind of power did you make?

    Spool time?

    What do we actually know about them? Lets take a sample from dsmtuners.com these guys know Holsets! (all credit to dsmtuners.com on this article)



    HX35:
    The 8blade hx35 has a 56mm compressor inducer. This is found on 1995-1998 cummins manual pickups. The compressor flows 52 lb/min according to the compressor map. The bolton BEP housing (0.55 a/r) is enough to push the limit of the compressor. There's several 500whp 8blade hx35 cars out there with the bolt on housing. It reaches 20+psi by 3500rpms in 3rd with 272 cams. Smaller cams would equal a faster spool speed in most cases.

    The 7blade hx35 has a 56mm compressor inducer. This is found on the 1999-2002 cummins manual pickups. The compressor flows 60lb/min according to the compressor map and logged results from a member here. The bolton BEP housing with the hx35 turbine wheel do not SEAM to have enough flow to really reach the potential of 60lb/min. But many have logged over 50lb/min so far and seen 500whp. The stock hx35 12cm^2 twinscroll turbine housing is a t3 flange housing. This mated to a NON-divided runner manifold has produced a 132mph trap speed with a full weight 1g AWD. This is about 600whp. So the flow is there with the stock housing if you use a non-divided manifold. The spool speed of the 7blade hx35 is similar to the 8blade hx35 with 20+ psi by 3500rpms in the bolton housing and by 4000rpms with the stock housing with a non-divided manifold.

    HY35:
    The hy35 has a smaller turbine wheel than the hx35. And, it has a turbine housing connection that does not allow for a bolton housing to be used. It does not have a divided housing so any t3 manifold can be used effectively with this turbo. It has the same compressor as the 7blade hx35. We don't know if te hy35 turbine wheel and housing is enough to reache the 60lb/min potential of the 56mm 7blade compressor. Some one try it out already!!! It should at least be a faster spooling viable option to the full t3/t4 50-trim.

    H1C/WH1C:
    In 1994, there was the Wh1c which has pretty much the identical compressor as the hx35 but with a Vband compressor cover. The turbine wheel is the same. It will bolt into the BEP bolton hx35 turbine housing. It has 4 bolts at the housing instead of 6. So you will need to buy 2 more bolts and use 6 washers cut to make a flat side. Honestly, I just used bolts that were cut a little short and the bolt head was wide enough to pull the chra to the turbine housing. No sealing issues. Since the Wh1c is for all practical purposes an 8blade hx35 the spool and flow is the same too.

    I have the big h1c. It comes on the INTERCOOLED 1991-1993 cummins pickups. It has the webbing for MWE but no groove cut like the hx35/wh1c has. This turbo I term the big h1c because it has a 54mm compressor inducer and same exducer than the 8blade hx35/Wh1c. The other h1c is the small h1c found on the NON-intercooled cummins pickups. This has a 50mm inducer but only 7blades and has no webbing for MWE. Less blades helps flow, but so does a larger inducer diameter. The most whp ever recorded on a gas 4cylinder with the small h1c was done on a KA24 nissan: 411whp. Since the big h1c has a 4mm larger inducer and the same turbine wheel as the hx35, it is safe to say that it flows enough for between 411whp and 500whp. The diesel sources state that it flows SLIGHTLY less than the early hx35. So 4lb/min less than the 8blade hx35 puts the flow of the big h1c at 48-49lb/min right where a 50-trim or 20g is. The small bep housing is all that's needed to get the most from the compressor and the spool speed is 20+psi by 3500rpms.

    HX35-40 hybrid:
    Keeping the long tradition of the marriage of sportcompact and hybrid turbos, there is the hx35 turbine and the hx40 compressor. It is strongly recommended to use the large bep turbine housing or the stock hx35 turbine housing with an non-divided t3 manifold for this turbo. The small bep housing around a t31 size hx35 turbine wheel is probably not enough to merit any of the hx40 compressor wheel upgrades. 20+ psi by 4000rpms can be seen in the hx35/40 with the hx35 12cm^2 turbine housing with a non-divided t3 manifold. With the large bep housing, spool times are to be determined. But likely similar.

    HX40:
    The 8blade hx40 has a 58mm inducer and flows about the same as a 60-1 (around 60lb/min) with ALOT better high boost efficiency and spool speed. It is the most common hx40 out there. The small bep housing with the hx40 turbine wheel is plenty to reach the full potential of the 60lb/min 8blade hx40 compressor. 20+ psi by 4100rpms with 272s.

    The 7 and 6 blade hx40 is called the super40 and has the 60mm compressor inducer. This compressor flows around 69lb/min. You can get this wheel in billet style (think HTA). The non-billet wheel spools as fast as the 8blade hx40 in the bolton bep housing and has done 653whp at 40psi per the holset results only thread. Billet should spool even faster. The t3 .70 a/r BEP housing slows spool about 400rpms. But reports show a significant gain in flow per psi. So expect more power at lower boost with that turbine housing.

    H1E/WH1E:
    The Wh1e is like it's little brother the Wh1c. It mirrors the hx40 8blade in every way except that it has a v-band compressor cover and a 4bolt chra-turbinehousing pattern. It will consequently bolt into the hx40 bep bolton turbine housing and this is plenty of flow to max out its 60lb/min compressor.

    The h1e is like it's little brother the h1c. There are different size compressors. . . BUT there are also different size turbine wheels too. Check measurements before buying this turbo if you plan on running a BEP turbine housing. There are lower flowing compressors than the 58mm 8blade that are out there. So this turbo may not flow any more than an hx35 if get the wrong one. You need at least a 58mm compressor inducer for this to be a worthwhile turbo vs the proven hx35 or 8blade hx40.

    HX52:
    This is a big sucker. It is commonly found on the Volvo Semis and usually has a billet compressor wheel. It flows 88lb/min. There is no bolt on housing for it. If you want a bolton housing for this turbo, then you don't want this turbo. In fact if you want a t3 flange turbine housing for this turbo, then you don't want this turbo. You DO want this turbo if you're looking at a gt4294r or gt4202r. The turbine inlet is slightly different than a t4 bolt pattern. You can still get the t4 manifold to work just fine by enlarging the bolt holes.

    Misc.:

    Holset's don't spool slow. They spool faster than their garrett or mitsubishi counterparts. Diesel exhaust is cold and slow moving.
    The holset turbine wheel is a work of art. It has been shown to flow very well in a very small turbine housing. For example the hx40 turbine wheel in the small .55 ar bep bolton housing flows as much as a garrett gt35r turbine wheel in a larger .63 ar garrett t3 turbine housing. The hx40 with this configuration spools about 500rpms faster! You can upgrade to the .70 a/r BEP t3 turbine housing and have the same or slightly faster spool speed as the above gt35r with ALOT more flow per psi and consequently more horsepower per psi. This makes for VERY good pumpgas numbers.
    Holset patented map width enhancement. They do not have extended tip technology, but there compressors show more efficiency than their garrett or mitsubishi counterpart.
    They have superback technology witch leads to VERY, VERY durable compressors. The are designed to be overworked and underpaid.
    There are discrepancies all over the web concerning the compressor maps. Take what you hear/read with a grain of salt and a shot of tequila, and the worm.
    The holset is fine with stock 4g63 oil pressure from the oil filter housing. If you have no b shafts, you'll need a restrictor. The drain line is a garret bolt pattern. The feed line is different for different turbos.

    that info pops up on every site , theres another site i got some more info from ill look for. the hy is actually the same turbo im buying, if i get bored, ill find an hx35 and do a hx40 hybrid. i should be ordering mine this weekend finally. i talked to a few people who used them on honda's and they all told me to skip the hy and start at the hx35. basically cause i wouldnt have much of a problem spinning it, and id get more in the end. the only difference in the hy to hx, is the hy you get what you see, the hx, theres actually a few different turbine, and turbine housing options, along with other hybrid options... the hy and hx will do around 60lb per minute, its more than a gt30r and i believe a tad less than a gt35r.... the hx40 wheel i think i read does 70lbs? ive read so much crap lately its kinda blended together, but holsets the way to go for a cheap alternative to a bb turbo... find an hy or hx from some form of commercial equipment and get the water cooling option too.... i seen an hx30 from a bobcat skidsteer on cl but couldnt tell the center section due to ****ty pic...lol....


    heres some more from turbo-mopar.com go here for pics from what i just posted...



    Guide to Dodge Cummins Holset Turbochargers
    This article was written by rbryant on 02-17-2009.


    Introduction:

    Due to the number of Dodge Cummins diesel engines in the '90s and early '00s Holset turbochargers are currently available and are cheap (at least in used form)

    In order to sort out both what to look for and to document the technical details of the Holset line this article is an attempt to be a guide to Holset turbochargers on turbo-mopars.


    Things to consider:

    Almost all Holset turbochargers that you will find on ebay and all Holset turbochargers that came on dodge cummins engines are oil cooled only. Unlike our turbos that have watercooled bearing housings most holsets do not. I have seen pictures of some HX35s that are water cooled and some HX40s that are water cooled but I have not seen a picture of a watercooled HY35 (but they do exist according to Holset.)

    The only real reason for watercooling is to help the turbo survive hot shutdowns. Of course nobody reading this article would ever shut off their car after beating on it without a turbo timer so that shouldn't be an issue now should it...


    One advantage of not having watercooled bearings is that there is no need to plumb the extra lines and the turbo can also be installed and removed faster.

    Holset HY35/HE341/HE351 turbochargers are about the size of a Garrett TO4e-50 trim compressor with a stage III turbine wheel and a .63 turbine housing.

    Holset HX35/WH1c turbochargers are about the size of a Garrett TO4e-50 trim compressor with a Stage V turbine wheel and a .89 A/R turbine housing.










    Holset Cummins Turbocharger Applications:




    Only the '94-'06 turbochargers really fit the needs of the 4cyl turbo community. the 18-21cm^2 turbine housings are simply too large. These could of course be used with a newer turbine housing or an aftermarket one but with all of the '94-'06 turbos out there it hardly seems worth it.





    Compressor Information:


    The compressor wheels actually match up quite comparably with the Garrett TO4E-50 and GT3776 compressor wheels.



    These overlays show how closely similarly sized compressor wheels function even when the designs are quite different! (images obtained from the squirel performance turbo calculator with a 2.4l engine @ 350hp)

    HX35 vs. T04e-50








    TO4e-50 vs GT3776 (not much change in heart the "modern" wheel is there...)





    Compressor Inlets:

    Compressor Inlet with silencer ring. These rings were installed at the request of dodge in order to keep inlet spool/whistle sounds to a minimum. Some people claim that removing them results in increased performance but nothing has really been proven thus far.




    Here is a picture with the silencer ring removed. This shows how the anti surge groove works. It allows for air to recirculate when the turbo begins to surge thus avoiding compressor surge in some cases and widening the usable portions of the compressor map.














    Here is a comparison of the HY35 (same as late HX35) and HE351 compressor housings. The HE341 housing (not shown) is the diameter of the HY35 with the shape of the HE351.









    Turbine Information:



    Holset lists their turbine housing size in cubic centimeters (cc or cm^2) instead of A/R as we have grown to know and love from Garrett. I have found a table that converts the Holset specific housings to A/R but there has been some question about how accurate it is so take this with a grain of salt.






    6cm2 = 0.41 A/R
    7cm2 = 0.49 A/R
    8cm2 = 0.57 A/R
    9cm2 = 0.65 A/R
    10cm2 = 0.73 A/R
    11cm2 = 0.81 A/R
    12cm2 = 0.89 A/R
    14cm2 = 0.97 A R
    15cm2 = 1.05 A/R
    16cm2 = 1.13 A/R
    17cm2 = 1.29 A/R
    19cm2 = 1.37 A/R

    Turbine Outlets:



    The turbine outlets use the same bolt on flange (unique to Holset) for the WH1c, HX35, and HY35 turbos. The HE341 and HE351 use a 4" v-band outlet.
    Notice that the HX35/WH1c wastegate hole and puck is smaller.









    Internal Wastegates:



    The HY35 models appear to have a cracking issue on their wastegate holes. Notice there are two variants here. The upper left is more prone to cracking than the lower left but this rarely matters and also exists with our stock Garrett turbos. The HE351 has solved this issue by being much thicker but the hole could use some porting as it is smaller than the HY35.








    Turbine Inlets:


    The WH1c and HX35 have a divided turbine scroll and the wastegate is not only small but also is only on one half of the turbine housing. This is just fine on a cummins diesel that is pushing 20+psi all of the time but it might not be what we want when on the street. Some people have attempted to enlarge the hole, grind back the divide or have simply given up and ran an external wastegate.










    Turbine housings have the area of the housing cast into them in the turbine inlet.









    Bullseye Performance (BEP) also offers an aftermarket housing for the WH1c/HX35/HX40 in .70A/R with a T3 inlet and 3"vband outlet for ~$250.

    This with the rare watercooled HX35 or an HX35 running a watercooled HX40 center section would make a really top notch setup!










    Fitment:
    The compressor housings on the newer HX35, HY35, HE341, and HE351 all have a locating pin that positions them to the stock configurations for the Cummins trucks. In order to use them on a custom application the pins will almost always have to be removed in order to allow the turbo to be positioned in the correct angles for the housings and to put the oil drain in the correct position of no more than 30 degrees from straight down.

    The pins can be removed by taking off the vband clamps and separating the housings. The housings can be a real PITA to seperate especially the turbine housing. Note that they come off all of a sudden when they separate so don't drop one or kick save it when the turbine is falling straight down when wearing shorts (long story). One side effect of removing the pins is that for compressors that have the integrated wastegate bracket it probably won't be in a usable position anymore... I simply cut the bracket off from mine and blended the housing to where you can't even tell that it was ever there.

    For the compressor housings that have a vband you can either cut it mostly off leaving a lip for a silicone hose, buy a 2" vband connector to weld to your pipe, or cut off the vband and weld on a new piece of pipe depending on your preference.



    Some applications such as the mexican stratus turbo manifold may be able to get by with simply taking it apart pulling the pins and rotating the center housing to have the oil drain on the bottom leaving the wastegate bracket on the compressor in the same position relative to the turbine housing. Other installs such as mine move everything and require a custom bracket be attached either to the head, welded on to the compressor housing, or bolted to the turbine housing (not something I would recommend due to heat issues).




    Oil Feed and Drain Connections:

    Oil Drain:

    The Oil Drain is easy because it uses a standard Garett T3 fitting. These are readily available with direct AN-10 connections or 1/2" NPT threads.

    AN -6 Oil Feed Adapter:

    The easiest way to connect the oil feed line is with the original Holset oring and an AN-6 Adapter with the following specs:

    AN Flare to Metric, -4 AN to 12mm x 1.5 Male.


    They are readily available from Summit racing:

      Yea see I was having trouble finding either a formula or accurate chart to convert the cm of the housings to AR...

      if the above is correct, its going to be a little too slow spooling for my tastes, anybody got any experience with these turbos?

      I have been eyeing the HY35 thinking it would be a good alternative to a t3/t4 50 trim, but was hoping I better hot side size options to keep my quick spool. I see 12.5 psi by 2800 right now. Im not looking to have full boost any higher then 4200 really

          IIRC the HY35 was at full boost by like 3500 and makes damn near 300whp at 15psi.

            the hy is also only good for about 30lbs, where as the hx's will flow enough for a bit more from the larger turbine housing... ive seen 40+ from an hx35 on some of the other forums, with the stock compressor wheel...

              Yyou guys wouldnt want my holset. Its set for 32psi and reaches full spool at 1200rpm. Produces 510hp at 1800rpm and 1900 ft lb tq at 1200rpm. Then again it does pull 80,000lbs down the road and is the size of a human head

                funny you say that, there was a few semi holsets on the local cl a guy used to make jet engines from ...

                heres a link to a youtube vid i dunno what turbo that is ,possibly a holset, but its pretty cool...


                When it gets too cold to race we have to do other stuff to entertain ourselves!!!

                  heres some more info ive found that isnt listed here...


                  this was a thread i found comparing the hy's to the gt3582r


                  The hy flows about 57lbs a minute and measures the following

                  Compressor minor/major: 52.75mm/77.84mm
                  Turbine minor/major: 57.98mm/65.20mm

                  The GT3582R flows approx 61 lbs
                  Compressor minor/major: 61.4mm/82.0mm
                  Turbine specs: 68mm w/ 84 trim


                  and some lb/min ratings of the holsets:

                  -Hy35, flows approx 57 lbs/min
                  -Hx35, flows approx 60.85 lbs/min -He351cw (Spools faster than the hx35, but makes the same power) flows approx 60.85 lbs/min
                  -Hx40, flows approx 70.10 lbs/min
                  -Hx45 (can't find the flow at this time)
                  -Hx50/52 or 55. flows approx 99.20 lbs/min
                  -Hx60 (Notice I didn't say HT60), flows approx 125.66 lbs/min
                  -Hx82, flows approx 198.42 lbs/min

                  compressors,turbines, and housing options:

                  wg=wastegate ng=nongated

                  WH1C / H1C

                  HY35

                  HX35 56mm inducer.
                  8 blade 56mm on the pre 98.5 models.

                      I thought that guy with the Red MX3 in FL had a Holset on his bp... Had that and 550ccs and put down way good numbers.

                        this info is incorrect the hy flows 60 lbs a minute because it uses the same 7blade compressor wheel as the hx35 it also flows the same as the crappier hx40 wheel. the only limiting factor is the turbine housing but it is at a power level that no here is going to reach. there has been guys getting upwars of 550 whp. the reason most of the honda guys go with the hx to begin with is that they are running a static compression ratio from 10.0:1 and up which would creat too much backpressure with the HY turbine housing

                          i absolutely love my hy35 on my bp miata. starts building boost before 3k and hits 8lbs by about 3300. i need to play with the gains on my ebc and see how much quicker i can get the spool up. the turbo makes a ton of noise and i wouldnt buy another turbo. as soon as i replace my clutch i plan to turn the boost up and get some dyno numbers.
                          my setup:
                          log manifold and 3" dp
                          tial wastegate and bov

                              Pretty nice looking setup. You've got that turbo bolted up to a t3 flange?
