Looking at the complete BD super B twin turbo kit. Is anyone running this kit on a 2nd generation 24V. Do you like it, hate it? Wish it had something it did not come with? Just trying to get an idea what kind of a kit this is. Jegs has the kit for 3078.99 for a 98.5 / 02 Cummins. Figure in another $ 450, for an ATS manifold, and $125 for the downpipe. I know this is not an over the top crazy power kit. However for your average truck that does not do much towing, sledding whatever it does not seem like a bad deal to get into the world of twins?

 

I only wish I could run it. It's probably the cleanest twins package you can get, and just HAPPENS to be affordable and have good performance.

Keep in mind that BD is very conservative on the HP numbers they quote. You could probably make 600+ of "dyno" hp with this setup easily.

When BD says 500hp, they mean 500hp all day every day uphill and down.

I intrested to find out what else i would have to do to run this kit on a 01' w/ everything stock except the air filter/exhaust...

Injectors?
CPU?
Clutch?


Anything I would need to run this kit on my truck safely, please let me know

 

Injectors: Mach 4s
Clutch: Con FE from South Bend Clutch
CPU/"box": TST powermax OR Edge Comp OR Blue Chip FMS

You'll also need an exhaust adapter to take the 5" outlet and adapt it to your 4" outlet on your existing exhaust. (The BD kit uses a 5" outlet, right?)

 

I will try to call the tech guys in the morning to find out if you would need an adapter.

 

From what I've read/seen I hear they work well on 24valves but fall a bit short of supplying enough air when on 12valves.

That being said I would like to try a set. Quick spooling twins that can keep a continuous 450hp cool would be right up my alley.

 

I hear that. This will be the last summer I don't use my AC because my EGT's are off the scale on my single, in the summer heat. With no load.. no nothing..

 

i am running a hx55 with a 19cm exhaust housing and i run my ac all the time. you have something else wrong, heck i think you could run without a turbo and still run your ac running empty.

 

I'm running them on my 3rd Gen and they perform well. Spool-up is very fast. Not a set of twins you would buy to put on a competition race truck by no means. If you want to tow heavy and still race at the track on the weekends…..this set rocks.

The kit comes with a downpipe…..it is 4". They will give you a 5" pipe if you have a 5" system, but you have to ask for it and it ships separately. I believe they charge you more for it as well.

The only problem I have with them is their lack of an external wastegate. The exhaust housing and internal dual volute wastegate on the secondary are both huge….bigger than the B1-04 that they replaced. This helps the set run very efficiently without an external gate, but it's absence limits you to 60lbs of boost or less. They run really well up to 60lbs of boost, but that is their limit for efficiency. Any more than that and drive pressure will overtake boost pressure. I have run them up to 67lbs quite easily, but obviously that is not where you would want to run them all the time. 60lbs of boost or less is where they perform their best. Mine currently produce 63lbs at WOT with max fuel. Getting boost to stop where you want it without an external gate is not easy. Lots of adjusting in small intervals on the internal gate. I would like to get them back down to between 58 - 60lbs max on a 1/4 mile run……that is the range where they run their coolest.

on edit: I got mine from Jegs as well. I use to have a friend there and paid in the neighborhood $2,700 delivered for the 3rd Gen kit that retailed for $3,600 back then. Now the 3rd Gen kit retails for $4,600 and Jegs still has the best advertised price on this kit at $3,800.

 

How much cooler are your egt's verses the old b1-04?

 

Roughly 400*F with my mods, depending on the situation....sometimes less.

On completely stock power with something doing just boost fooling for me, EGTs won't go over roughly 650*F with about 38lbs of boost.....that is a better example. Dual stage compression from any sets of twins cools extremely well.

 

AK RAM, did you do the install yourself or have a shop do it. If you did it yourself how did it go? A good weekend project?

Thanks!

 

I did the install myself and it took me three days. There is nothing hard about it, just time consuming. Pretty straight forward install and the instructions were very good. I took my time, had to make a couple trips to town to pick up tools I didn't have, and killed several hours each day waiting on a friend to stop by to give me a hand at times. I didn't plan very well before I started and just jumped in there. If you don't have to stop for tools and have a friend handy to help hold stuff, it is easily a two day job (very long days).

You will need some very big allen keys for the manifold bolts. Either a very long punch or very long flathead screwdriver to seat the oil drain fitting for the secondary into the side of the block (press fit). A good set of torque wrenches, ft lb & inch lb. Other than that just standard sockets and wrenches. You will need a friend to help lift the primary turbo up to the hot pipe flange while you get the bolts started, then will need someone to hold these bolts from the bottom while you tighten the nuts down. You can't do those two steps by yourself. The rest is a one person operation.

 

MoreSmoke, not to deter you from getting twins, because everybody 'NEEDS' twins lol But, you definately have something very wrong with your truck or EGT gauge, if you are getting high EGT's cruising.....

Good report "AK RAM!"

For those of you that are considering going to twins, "AK RAM" is right about those hex head
manifold bolts! IMO,.....they are a PITA!!! What my son and I did on our trucks was go
to "Fastenal" and buy some of their stainless steel regular head bolts in the same size as the hex head bolts that come with the ATS Manifolds. They will never rust, went in easy, and are
ALOT easier to get out if you ever want to take the manifold off again. I will get you guys the exact size/length etc. along with the "Fastenal" part number if they have one.
