Engine/Transmission (1998.5 - 2002) Anyone running a Super "B"?

[JSawtelle]

OK ... here we go.

In anticipation of higher EGT's I am asking for a lil' help here... ... ...

Just bought the 4000 Lbs (dry) camper and we are going to tow the rock crawler that weighs 4250 lbs + trailer, behind.

I am anticipating needing more air in to the motor, so am wondering if I should go for the turbo now?

I have not towed yet with all the components combined, but I am trying to make the eduacated guess from these forums that I will NEED a bigger turbo!!

Thinking of a BD Super "B"... ... .

Thanks... . You folks have been fantastic with advice so far. The mods I have made thus far have been from a lot of research and reading , for countless hours, the pages of this Forum.

TURBO DIESEL REGISTER!!!

Thanks Again!!

That would probably be a good turbo if you have stock or small injectors. I ran the super B with the BD 90 hp injectors and it ran really hot. I was never impressed with the spool up either.

 

[JSawtelle]

Thanks for the response, BILLVO!

Anyone else????

Well you are going to want an exhaust brake most likely also. So if you go inline on that, you do not limit your Turbo choices. I went from a HY35 to PDR35W12 and it works great up to around 6 or 7,000 feet, after that I have to watch my EGTs still. Your 3. 56 gears are going to hurt you also, as you will not use OD that much. With 4:10's and 19,500 combined weight I can run OD over 55 mph and run most freeway hills at 60-63 mph without a problem. Mountain passes, I have lots of power in 3rd.



Pick up a used HX35W12 and try it. PDR will upgrade it for a very reasonable cost to a PDR35 if you want it to spool a little faster. SNOKING

Dodge is full of hot air!!

Dodge's hot air! Wonder what his pyro was reading.

Call me crazy, but with what you are talking about towing, you shouldn't really NEED anything. The turbo would be cool and help pull hills and whatnot, but you should have no real probs with your current setup.

 

[SnoKing]

His truck is 7500 to 7800, Camper 4500+, trailer 4250. That is 16550, or fairly light! HY35 still is not the best cooling turbo. SNOKING

more power + turbo upgrade

I would recommend a timing chip( EZ COM, VAN AAKEN) for a little extra power. I have a super B and like it. I also have had a hybrid 35/40 and it was not bad either, I am a bit to fueled for the hx35/40, so I went up to the super B.



I am going to be selling my 35/40 with a freshly rebuilt.



towing 10k above truck weight you are going to be 900-1150 driving and going up hills. It just takes a lot of power.

Actually weighs in at a whopping 6700 lbs w/o my fat butt in it. The reason i know this is when i purchased the vehicle in Iowa and brought it to California I had to have it weighed in order to register it. I think they charge by the pound or something... ... .



So Snoking you feel I will have other issues than just a turbo... . My gears could be the problem to come?

 

[PC12Driver]

For towing, you'll want to keep the turbo as small as possible. Especially with an auto with a tight TC, and with tall gears. Even more so if you plan on towing at any higher elevations. Bigger turbos cool better on top, but they'll run hotter on the bottom if you don't have the RPMs to drive the charger. And the driveline configuration of your truck won't let you build RPMs quickly at all with a load on. She'll just kind of wallow and smoke until the RPMs are there. It's not a great feeling to try and climb a hill from a standstill but not be able to accelerate because you don't have the RPMs to get the turbo going.



Anyway, my been-there-done-that advice is to turn off the Comp, run the Smarty on a mild setting, and see what happens with your egts. If you think you need more, take SNOKING's advice and find a used 35/12 and try that (a 35/12 and a Smarty will make a killer, worry-free towing combo). Baby steps are the key. Unless you have the coin for twins.



In my case, I went to a hybrid 35/40/14 (not really a big jump) that would only cool if RPMs were over 2100. That made for a smokey and sluggish tow rig (and a lot of shifting). My current turbo is better (slightly), but it still doesn't pull like that 35/12.

OK, I missed the part about it being a 2x4. Find a HX35W12 first and go from there. SNOKING

"Unless you have the coin for twins. "

This has crossed my mind... .



Wouldn't this coin include having to O-ring the heads??



Thanks Snoking your advice threw this has been great!!

 

[JSawtelle]

Super "b"

Still have not heard from anyone who is running one of these... ... . Anyone???

 

[NHays]

I do

OK. I have ran a Super B and really liked it. Very nice. I think, however, you may want to stay with a smaller turbo being you have an auto. I ran the B with the 97' and had #10 fuel plate. I loved the way it spooled and it did keep things cool at 345HP. I had minor problems spooling at stock power level. I would recommend an HX35 as a small upgrade for your auto. Having been there done that with 3. 54 gearing at high altitudes, I noticed that the Super B was slightly sluggish at best. I don't know what kind of power your making. Just know this, If you get the bigger turbo, expect a big difference from your stock turbo. Things I noticed. Truck drove more like a semi, very flat power band, cruise temps were up a little, towing temps down ALOT, little better MPG towing, Poorer MPG in town.

 

[JSawtelle]

Twins question!

Thanks NHays... . Frickin' awesome thats the things I wanted to hear about.....

Great feedback... next question...



To run twins do you have to o-ring and stud the Head???

 

[darkhorse]

Still have not heard from anyone who is running one of these... ... . Anyone???

I'm no expert in this area but it's my understanding that you don't need "o" rings until the pressure goes above 50 psi.

 

[highmilage94]

I do not have one of these turbos, but I have done my research on it as well as others... . For the money I would go with a Super 'B' Special. It is only 200 more I believe and it is a much better turbo... The Reg. Super b is not much bigger than stock, but the special has the same sizes/ specs. As Industrial Injections SPS 64. As for too much boost, with stock timing you can run 50, but 'Highfinance97' has ran 50 with 16* of timing. Timing is a much bigger head gasket killer than boost. And besides, you can always get an adj. Boost elbow.

I have a 64/12 in my truck right now, and I cannot do not recommend it for towing. I have a hard time keeping it below 1200 degrees on hills. It is an improvement over stock though, I used to peg the pyro easily with the hx35. I want to downgrade it to a 62/12, and maybe switch to a 14 turbine section.

 

[DCreed]

for the money ,have you looked at the HTBG 57/12 ? I'm running it now and with SMARTY and 100hp injectors it pulls great! I also have the 3:54 gears w/285-75 tires if I pull in w/OD off cant get over 1100* and can pull up to 42psi. spools 0-10 psi off idle and lights @ 1500rpm then boost/power is in your control. SMARTY on 5 smokes only when lugging under 1500. controllable. just a thought.

 

[16919]

A 64/12 is waay too big. A 62/12 is still big... you need a hybrid or an hx 35. An hx would probably be the best and cheapest choice.
