Engine/Transmission (1994 - 1998) anyone have a bd super b turbo?

[TBurow]

i am contimplating buying a super b single turbo to replace the hx-35 on my 96. does anyone have any info on this turbo? it comes with a 4" downpipe which will work nicely to replace my 3 to 3. 5 to 4" downpipe.

That is what I am running for the last 20k or so. No complaints at all. Helps me stay a bit cooler while towing. It comes gated at 38psi. I left it alone, seldom go over 30 or so unless I push it.

 

[TBurow]

i also have a hy-35 off a 2001 would the hy or the super be a better turbo?

 

[TBurow]

no-one has an opinion, wow things have changed around here. no one even could ask about one before without an argument about brand x being better than brand y. i bet if it was a twins question all sorts of people would chime in.

 

[HPetrat]

Was hoping for more people to chime in as well, as I would like to go to a Super B or Super B Special.



Twins would be nice but the budget at this time makes for a difficult sell to the "finance department".

Know what you are saying. Another thing about going with the BD is if you want to upgrade later to twins, they will sell you the kit so you can use the Super B you already have and not have to get the complete twin setup. I would love to go with their towing twin setup, but the finance dept. "me" is being reluctant to drop the coins for now.

My Super b is sitting on my bench grenaded with only 50 k on it. Before it scattered , I will say that spool up was great (gated at 45psi) and it served ok for pulling. If you want something more than a 'off the shelf turbo' try giving Eric at Browns Diesel ( California) a call 559/867-1111. Eric spent a lot of time answering questions and helping me with purchase of my new turbo. FYI- mine was on a VP motor

 

[TBurow]

GHedger, what was the cause of your turbo failure? overspeeding, bad bearing? but it was a definate improvement over the stocker, thanks

 

[hsmith]

Did not want to hear that, but like I said, I don't push mine hard. Don't think I have ever seen over 35 psi and even then briefly.
Anytime we increase power to our trucks we take a chance of things breaking well ahead of one left alone.
I'm going to hold on to the original 35 just in case. But then it will be home and where will I be? LOL

I did the BD Towing twins..... was looking at buying another turbo also. Was not satisfied with the B-1 I had and looked at different options. If you want the best of both worlds,your only option will be twins. I have my low-end cooling and snappy response of the factory turbo and seemingly endless cooling on the mid and high end. I can lug mine down to 1200rpm now if I choose without heating up and towing up grades,I am not limited to driving by the Pyro anymore... . although,now I have to watch my transmission. Plus,I love the way those things sound..... of course it gets alot of attention from the younger crowd. I can't even have a date night with my wife without some teenager asking me to smoke an intersection



Go buy another turbo... . try not to be dis-satisfied... but you will long for the towing prowess that comes with twins. Properly set-up of course. Cost is high I know,but when you factor in going through turbos that fit your driving style... . it is cheaper to just buy what you need and not have a bunch of old turbos sitting on your workbench

for close to the cost of a new single, you could drop an S400 under the stock HX35 and be pretty happy.
The super b is a 57/65/14 turbo and the HX35 a 56/65/12. so the B isnt so much bigger but it is a newer design and will run happily up to 40psi. after that its just moving hot air and taking undue stress. The super b is the same as an HTBG from HTT and they are good for about 400hp.
The special is a 64/71/14 and is much bigger than stock and slower to spool but cools closer to 550hp.
Both use an HX40 style down pipe.

i am not looking for a race truck, 450 hp is more than my 300k mile plus truck will ever see. it is used for hauling junk cars on my triple axle trailer and occasionally going to the home inprovement store. the most i have ever towed was 28,000 lbs for 50 miles and dont plan on doing it again. just looking for a slight improvement in flow over the stock turbo which seems to be a restriction in the top end. i was looking at the super b or the aurora 2000 both seem to be in the same price range but the non w/g on the 2000 kinda makes me lean toward the super.

OK, so can a plumbing kit be had minus the turbos? I know BD will kit you if you have the B already. I'm talking about the B under the 35. I have both and know nothing of a correct combo but am leaning in this direction.

 

[TBurow]

or how bout this, is there some refrence info on what s300 will work on our trucks?

Yes.

NO.

You cannot do twins with those two as they are nearly identical and wont work at all. If you ran them side by side like a gasser then the ex. housings would be added together and become a 26 and VERY laggy with little top end boost. If you tried to compound them it just wouldnt work as neither can flow enough to supply the other.

or how bout this, is there some refrence info on what s300 will work on our trucks?

lots of them. what exactly do you want to know? Try checking out some sites like Industrial injection or High tech turbo or many of the other vendors that list HP and fueling references for the turbos they carry. and trust me, if they say UP TO XXXhp, thats all its good for.
On a DD/tow vehicle that will see lower rpm/fueling use then a smaller turbo will be better 57,60,62 comp/65,71 turbine/12,14 housing
if you use it for play like drags and pulling then a 64 or 66 with a 71 or 74 and a 14,16 housing.
Each time one of the #s goes up, so does the lag and RPM range. you can get around it to some extent by mating say a 66/65/12 but it will surge like crazy.

 

[TBurow]

ok, thanks DCreed, just looking for a cheap option like buying a rebuildable or used one and getting it rebuilt. i see alot of s300's on ebay and other sites but they all have huge exh housings.

 

[DCreed]

there are 2 different standards of measure, A/R and CM2. So to convert, a . 070 is a 12, and a . 080 is a 14. also pay attention to the outlets on both ends or you will be pulling your hair out trying to get it to fit, not to mention oil inlets! As someone who has "been there done that" I would just bite the bullet and buy one meant for our trucks.
