The 8blade hx. 35 has a 5. This is found on 1. The compressor flows 5. The bolton BEP housing 0. Theres several 5. It reaches 2. 0psi by 3. Smaller cams would equal a faster spool speed in most cases. The 7blade hx. 35 has a 5. This is found on the 1. The compressor flows 6. The bolton BEP housing with the hx. SEAM to have enough flow to really reach the potential of 6. But many have logged over 5. The stock hx. 35 1. This mated to a NON divided runner manifold has produced a 1. AWD. This is about 6. So the flow is there with the stock housing if you use a non divided manifold. The spool speed of the 7blade hx. HY3. 5 The hy. 35 has a smaller turbine wheel than the hx. 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 t. It has the same compressor as the 7blade hx. We dont know if te hy. Some one try it out already It should at least be a faster spooling viable option to the full t. H1. CWH1. C In 1. Wh. 1c which has pretty much the identical compressor as the hx. Vband compressor cover. The turbine wheel is the same. It will bolt into the BEP bolton hx. 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 Wh. 1c is for all practical purposes an 8blade hx. I have the big h. It comes on the INTERCOOLED 1. It has the webbing for MWE but no groove cut like the hx. This turbo I term the big h. Wh. 1c. The other h. NON intercooled cummins pickups. This has a 5. 0mm 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 h. KA2. 4 nissan 4. Since the big h. The diesel sources state that it flows SLIGHTLY less than the early hx. So 4lbmin less than the 8blade hx. The small bep housing is all thats needed to get the most from the compressor and the spool speed is 2. HX3. 5 4. 0 hybrid Keeping the long tradition of the marriage of sportcompact and hybrid turbos, there is the hx. It is strongly recommended to use the large bep turbine housing or the stock hx. The small bep housing around a t. With the large bep housing, spool times are to be determined. But likely similar. HX4. 0 The 8blade hx. ALOT better high boost efficiency and spool speed. It is the most common hx. The small bep housing with the hx. The 7 and 6 blade hx. This compressor flows around 6. You can get this wheel in billet style think HTA. The non billet wheel spools as fast as the 8blade hx. Billet should spool even faster. The t. 3. 7. 0 ar BEP housing slows spool about 4. But reports show a significant gain in flow per psi. So expect more power at lower boost with that turbine housing. H1. EWH1. E The Wh. Wh. 1c. It mirrors the hx. It will consequently bolt into the hx. The h. 1e is like its little brother the h. 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 5. So this turbo may not flow any more than an hx. How To Install Plugins To After Effects Cc 2016. You need at least a 5. HX5. 2 This is a big sucker. It is commonly found on the Volvo Semis and usually has a billet compressor wheel. It flows 8. 8lbmin. There is no bolt on housing for it. If you want a bolton housing for this turbo, then you dont want this turbo. In fact if you want a t. You DO want this turbo if youre looking at a gt. The turbine inlet is slightly different than a t. You can still get the t. Misc. Holsets dont 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 hx. The hx. 40 with this configuration spools about 5. You can upgrade to the. BEP t. 3 turbine housing and have the same or slightly faster spool speed as the above gt. 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 hearread with a grain of salt and a shot of tequila, and the worm. The holset is fine with stock 4g. If you have no b shafts, youll need a restrictor. The drain line is a garret bolt pattern. The feed line is different for different turbos.
