Anyone know the rough specs of "Dave's" build?i think his screen name was 953 racer or something...apparently he did it right somehow
I figured the part no. would tell us that but alright i'll try... what dimensions are you looking for? the compressor wheel? (the blades in the picture?)I think its 9cm across (diameter) but im at work right now. I'll clean it up some today at 8:00 after dinner, take some pictures, measurements and the like.You want how tall the wheel is? the width of the inlet housing? Gimme some qualitative and i'll get you the quantitative.
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. Mine is the 7 blade 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.
