Hey does anybody know of the website for B1 Bomber turbos? I know there is one because I have seen it. I need to make a decide on a new turbo but need a little help. I am runnig dd2, comp(no wire yet) ddt 89, I also want to keep hx35 cofiguration for pac brake. Thanks for your help.

I think I just answered this same question on another site, but the ONLY place I have seen a break-down of the "B" line of turbos was HERE

If this link is against the rules because it's not from a sponsors website, then please remove it.

I wonder if I would be better off changing to a pdr cam and staying with my pdr hx35? What do you guys think?
Thanks

 

Depends really. What are your goals for your truck? What are you hoping to get by swapping the turbo, or going with a cam instead? This will help in telling what you need.

 

I'm worried that when I tap the wire my egts are going to go through the roof. I'm not realy into drag racing, but sometimes I do like to get onto it a little. Just would like to eliminate problems before they start.

 

Original question = no web site for B-1 Turbos. Sold by Mfg only through dealers and advertised by them.
Comp, DD2's and an HX-35...your egt's will "go through the roof".
I would guess you'll have 3-5 sec to get to 1500* and climbing...but if you want the pac brake, what choice is there other than maybe bigger turbine housing for your HX-35? None I have heard of.

Piers has a B1 turbo that should solve your problems. It has the same size outlet as the stock 35, so this will help out.

 

Sp with B-1 expert, they don't recommend the direct hook up to stock 3" exhaust...It raises drive pressures resulting in at least 100* higher EGT's over the EX4. This makes sense, if you think about it, and kind of defeats the reason for spending money on the B-1 turbo in the first place.

Why spend top dollar for a bigger turbo and than choke it?

Does the EX4 housing raise egts over regular b1 housing? If you are not starting with a 40 is there a reason to use EX4 housing?

 

The EX-4 housing will lower EGT vs. the standard EX-3 housing. The EX4 is a 4" outlet, vs 3" for the EX-3, i.e., HX35 outlet.

Larger outlet will result in lower drive pressures and lower EGT.

If you want/need an exhaust brake and don't already have one, Pac Brake and a few other outfits make a 4" inline ex brake that mounts downstream of the turbo. IIRC, they do require an external air source.....

 

EX4 is the standard B-1 turbine housing exhaust stack. V-clamps straight onto a 4" exhaust pipe with no restrictions to cause backpressure (higher drive pressures)...which is the reason for wanting it.

What is the difference in these two units?

B-1 Bomber - Mid to High HP w/manual trans

B-1-EX4 - Same as B-1 with HX40outlet

 

See this thread for info on B-1 line...4 basic models.

Think you have seen that and posted there.

I believe B-1 Bomber is the full name for the B-1, so they are the same.

Very heavily do NOT recommend the EX3 outlet on a B1 series charger of any kind, except the KSB1-2. We've seen EGT increases in the 100F - 150F range with the EX3 outlets, combined with an EGT increase of 75F-125F with a turbo mount brake. As Rowland commented, you've taken alot of money and pretty much dropped it down a hole.

If you're dead set against swapping out your turbo mount brake, you might as well pick up a hybrid 40/35 and when towing, keep your Comp box on the lower settings to keep EGTs in control. EGTs with KSB1-2 and exhaust brake will be pretty much identical to EGTs with a 40/35 hybrid and exhaust brake.

If you're willing to do an inline brake, I'd seriously consider the KSB1-1 or KSB1-2 with either the full B1 outlet, or the EX4 outlet. The B1 outlet offers _slightly_ better EGT control, in the 25F region, but the EX4 outlet is easier to find a downpipe for. We normally do EX4 outlet chargers around here.

Didn't notice this post before, but we've had the B1s on our web site for about 2 years here:

http://www.wildcatdiesel.com/dodgeturbo.htm

That link will also give you some pictures of the internals of the B1 turbo, and a brief write up on some the unique aspects of the function of the chargers.

I also noticed that the other link leads people to believe that only certain chargers are available with the EX4 outlet, EX3 outlet or 03 outlet. ALL B1's are available with the EX3, EX4, or 03 outlet.
