I just saw a BD Super B going on a Cummins today....The "super B" is a 57mm comp, and a 65mm turbine
The "super B special" is a 64.5mm comp, and a 71mm turbine... which is what i have
was it on a 3rd gen truck?? cuz even just the super B would be a huge upgrade over the 9cm hotside on the stock turbo, that thing is big EGT maker

Hey Zac, does that have the wastegate on it or is that the difference with the 35w? We have one wearing out, and looking for a used replacement.are you asking on the original or new turbo?
but yes both the new and old are wastegated
old is only wastegates one volute... new does both and they are big

zac, have you loaded your engine much yet? im curious how it will pull while towing

but honestly I am amazed how it is working..... don't know why people say you dont want to pull with a 64?? unless it is that much different in a maunual truck?? I almost wish i would have went with a 66 as seeing how responsive the 64 is
At unloaded cruising i now see slightly higher EGT's and lower boost pressures.....(should help some with mileage from easier engine breathing). but with a little bit of load it will quickly trasition into good boost with out any smoke or hesitation.... then the EGTs stay way way lower than they would have with the stocker under any load
We will be hauling calves in a week or two so that will be 25k lbs.... see then what it does with a heavy load. Should get a vid showing all the guages when i am loaded like that accelerating and cruising loaded.
As of now i love it... and really see no absolute need for twins... I know now that i could go to a 66 if i needed more and still spool it to my liking
jacobs give your 2 cents, you rode in it and can attest to the spooling, EGT's, and power increase
Its still a tossup as to whether the 4K governor springs, torque converter change, or turbo swap made the single most impressive change all by itslef

64 sucks with a manual, even with a bigger pump and chip turned up all the way. it was annoying to drive, once it spooled it was decent, but the twins are soooo much better. we pulled a 25ft enclosed car trailer with a early 80's delta 88, fridge, washer & dryer, big tv, and lots and lots and lots of heavy boxes and tools and stuff from phoenix up to flagstaff (up a mountain) and with the monster pump, ddp 150's and the twins, it pulled amazing, and beleive me, we were doing 80 the whole way up and could still accelerate quickly

Old one, looking for one used and local. Wasn't sure if that works in place of the commercial 35w though.

I will kill you zac if you sell that thing.... :mad:

I am looking for one, but wondered if the hx35 works in place of the hx35w, which we have one that is wearing out. Everyone tells me something different on the difference between the two, just need one that doesn't squeal when the engine is at upper rpms.

If you need a replacement turbo talk to my dad.

well beahbum, hauled the calves and finally had it loaded heavy
works great for keeping my EGT's good and all that stuff in check but there is only one thing that i get that is a nuisance.
if i am in OD with the converter locked and i am going slower than 60 mph with a big load you cant go beyond 20psi or i get compressor surge which is gay but i can live with..... anything at or above 60mph i can go full throttle with a load
made a little gay vid to show what kind of response it has and how loud the compressor is at low boost especially
from a dead stop accelerating normally and i stab the throttle for a quick second. rolls from 15psi to 40psi like nothing
would be interesting to see the actual difference on a manual truck
you need volume, camera has had a horrible life
