    Intent is to post your mod list, an installed pic (engine shot), logs, dyno charts and track results of your car with a completed Holset setup.

    Please no discussion. Keep discussion to the normal Holset threads. Please also keep your post to one post if you can. This will keep the thread smaller, less clutered, and more concise.

    Summary provided by wiseman, Dsm-onster:

    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.


    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.


    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.


    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.


    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.


    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.


    • 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.

    2.31sec 70-90mph time with hellatious phantom knock (13 degrees of timing pulled). This is terrible for a turbine wheel to endure because of the resulting high EGT. but she's been good for a long while. 40lb/min logs to come after the engine rebuild. I've logged this high before, but on the old PC with a dead hard drive. Times this upcoming season.

    35/40 hybrid with only a 58mm 8blade hx40 compressor and the a full hx40 with a 6blade compressor. Impressive for 23psi and 25psi respectively especially considering the weight. A 4g64 only has .1L less displacement.

    Initial results with VGT fully closed.

    Will edit when I find some more of my material that I have posted. For now check out the link at the bottom of the post.
    Results with VGT wastegate actuator (14b stock actuator) connected, but external gate with no boost source.
    This is a log showing boost response. Conditions are steady state cruise at ~70mph on the interstate. 60-70kpa manifold pressure. Go WOT and 9psi of boost comes in about .95 seconds, then rises more slowly from there. Its been a while since I ran a 16g on my 2.4l but this is faster than I remember it spooling under similar conditions.
    Wheel sizes.

    I have posted stuff that I haven't posted here in a thread on HMT. Go there and read it if you are interested in the way I made it work.

    Turbo Talk - View topic - HE351VE Holset VGT Turbo Information NO 56K

    As far as people afraid to run one because of supposed high EGT issues with the VGT turbos. I only have limited testing so far, and didn't have an EGT probe installed in the manifold. I do know that at first I had EXTREMELY conservative timing in the MS due to having no intercooler. The timing was even lower than that, by about 10 degrees from the CAS being set incorrectly. My timing light was broken. :( Timing at the onset of boost was near TDC, and probably no higher than 5 degrees total. All 3 things(low timing curve, take away another 10 degrees, and no intercooler) tend to lead to VERY high EGT's, and I haven't had any issues with the turbo whatsoever.

    Well got back from the dyno, was a terrible day as usual when you want things to work out!
    Left here all ready running 34-35psi and got to the dyno and boost was 26-27 PSI!!!! somehow developed a HUGE leak along the last day or two! I tryed to turn it up and started to blow hot air and eventually maxed out the boost controller as the turbo was trying to do all i could.

    485.2 Hp
    429.9 Tq

    I didnt have enough tools to do a leak test with me so i just packed up and went home.

    BTW this was done on a MUSTANG dyno.

    As i have mentioned before had a big leak so boost on this run was around 30 psi or so.

    This will be a bittersweet post for me..



    Video: Turby dynos 400whp! Video by ronnie size the barbarian - MySpace Video

    399.27hp / 354.29tq
    430.05hp / 381.94 (uncorrected)

    This was at 30psi, 100% 93oct pump gas. The bitter-sweet part is, after making these numbers, I took the car home and blew the turbo doing a WOT pull -- wont make any boost now and smokes bad.

    Added: I was using a stock 2g timing map, with pulling a degree or two from 5k to 8k.

    All in all its not a bad time. My car weighed in at 3430 with a full tank of gas and me in it. I left the track with 3/4 of a tank so you be the judge on my official weight. We are hoping to go back in a week or so a little bit lighter and with a little more boost/timing :thumb:. Hopefully I will be able to edit with some better results.

    Ok so here is a couple slips on my 2.3 stroker/hx40 combo.....little background on the run....I made two runs on 17-18psi then when i turned the boost up, I must have caught my foot on the clutch switch/NLTS wires and pulled them apart. As soon as I hit 5500rpm where my studderbox was set I would hit the studderbox in every gear LOL.....so I made two good runs but only on 17ish psi. My logger cut out right after my first run so i couldnt do any tuning either. But it was running pig rich as my first log showed 02 readings at 1.03-1.05!!!! Wideband will be installed by the next track outting! here ya go....

    60ft 1.79
    1/4 mile 12.75
    mph 109

    60ft 1.84
    1/4 mile 12.80
    mph 108.2

    really cant wait to run some damn boost!!! Due to our elevation at the track (numidia raceway) we normally are 2-3 tenths slower then E-town or maple grove.

    just wwanted to update everyone on my results, so far at 15* timing and 26psi I'm flowing almost 53LBS/min on my T3 HX-40, 60mm,7-blade turbo. thats about 6 Lbs/min more per psi then my bolt-on hx-35. 93 OCT fuel, stock 19Year old 7.8:1 block with 111,000 miles on it

    latest log shows full boost at 5300rpms but my car shows full boost at 4600rpms.

    My thoughts are, completely different beast then the hx35, not a very good street turbo, but who cares when i give it gas. It sounds like an N/A Honda even with my thermal R&D exhaust until boost hits, thens its very loud. my fuel trims are off as i have an exhaust leak at the V-band from a warped flange. there is no end to the top end pull on my current setup.

    update: ran 12.02 @ 121mph on 23psi spinning all through 1st and then short shifted to 2nd and it bogged totally! My tires are down to the nylon cord on all 4 so Im getting tires and hitting the track again on Friday and Saturday.....hopefully 30+ psi and some very low 11's shouldnt be a problem!

    12.3 @ 117mph on a 8 blade HX35/40 hybrid (not sure on the exhaust side cm2). 2wd R32 Skyline with a RB25 swap on crappy nitto drag radials.

    11.8 @ 124mph with a trunk full of crap and a passenger. 6 blade HX40 with a 19cm ex housing on Mickey T drag radials. Best mph same night of 127. It's got mid 11's in it for sure. The motor is laying down though, so I don't know if I'll be able to do better anytime soon.


    I didn't see where you actually added my times above or I wouldn't have thrown them up again. Sorry :ohdamn:

    Holset HX35 7-blade (built by yours truly) @ 30psi in a BEP T3 .70 a/r turbine housing mated to an ERL manifold. Completely stock 6-bolt with 130k (no balance shafts), Comp 101200 Cams in a stock 1G head.

    1/4 Mile: 11.60 @ 121.52 on 9/16/09 @ Pittsburgh Raceway Park.

    **UPDATE 8/16/09** The HX35 powered Dave to a victory in the Bracket 1 class at the DSM Shootout this year. At 28psi and logging over 58lb/min of airflow, Dave's car just couldn't be beaten. The tired old stock 6-bolt is still going strong, although the plans include a mild build in the off-season.

    After Months of B.S. and waiting I finally got my car Dynoed. The run was done on pump gas at only 25psi because the boost controller (profec B) would not allow the boost to go any higher. Polk claims the dyno was reading the torque levels incorrectly and that the printout should show engine speed instead of RPM's so the RPM numbers at the bottom of the sheet are wrong. They said they only revved the engine to 7000rpms because the numbers started falling off after 6800 due to the stock head. They also said that the torque numbers were reading incorrectly (around 700 ft lbs) but that the car only actually made around 420ish torque.

    HP: 454.84
    Tq: 420ish??
