If we're talking bearing and shaft sizes, the B1's shaft is a full 1mm larger than a 40, and the bearings are much larger. I've got some comparison shots a little ways down on this page:

Thanks Rod. I'd like to compare wheel sizes but Ken has removed ALL markings on the housings and anywhere else you look other than the letters "JD" on the compressor wheel. Lenny said he thought Ken was having a John Deere style housing cast for this application. Here's the B1-04 compared to the HY-9...

Compressor side





Turbine side

Its actually an exclusive Caterpillar housing. Early on in 03, TAD was able to buy them direct from Schwitzer, but then Cat shut it down, so TAD had to get them custom cast or outsource elsewhere.

Cool. Thanks for the info Rod. Any idea from the looks of the pictures what this would compare to flow wise. I'm not looking for part numbers or proprietry info, just trying to find out what I'm working with here as I happily bomb away.

Thanks,

According to TAD, the B1 compressor side is capable of flowing almost 1000 cfm at 40 PSI. We did some snooping a while back at some Schwitzer maps, and did indeed find some maps that crossed over to the numbers Ken was quoting me.

On the turbine side, we've got a few customers running B1-04s. They've been able to dyno 500 HP+, but heat has been a killer on the street. The external waste has relieved many of our EGT issues on the higher power level settings, although until F1 gets their injectors ready for us, I don't think we'll see 500HP thats safe for the street.

A few more questions Rod,

By externally W/G the turbo is it the relief of the super high drive pressure that can help cool the EGT's down?

At the 500hp level how hot can these motors run with the B1-04's? I know that every truck is diffrent but can you give an estamate at what you have seen?

John at Floor It Diesel says he is making 590+ hp with a B1/TST/EZ at 60+lbs of boost. Is this capable?

I mainly run 5/5 TST daily and I have dynoed at 377 at this setting, 450 on 8/8, So lets say that a set of F1 EDM's or a pressure box and im at a good, less aggresive 450 on the street and want to tow light at say 3-4k, at the high 3-400 hp. Can the B1-04 keep me cool?

Thanks for your info Rod!

1) Yep. You get your drive pressures down and let the engine breathe, your EGTs will drop.

2) At 500 HP, the non-wasted B1-04 will TOASTY, in the 1800F range. Waste them out and you'll see those numbers drop significantly.

3) We've never seen 590HP period on a common rail truck. But John may know something we don't

4) The injectors are a large part of the EGT equation. Don's been giving me some EGT numbers from his testing data, and they are definitely going to be part of the equation when producing usuable horsepower on these trucks.

Thanks Rod!

But can you help me with 1 more question?

Say at 400 HP can a B1-04 keep me cool enough to tow at about 5000 ft with about 3-4000k lbs and still stay cool?

I am willing to go twins but I dont want to if I dont have to. I trailer race in the winter, if it cant keep me cool I will put water/meth on to help drop some temp.

what would you say with the TST/ dons 40hp TST EDM's, B1-04 and water/meth at 400-450 HP towing stated above?

Thanks agin Rod.

Jeeeeeezzz....ask a hard one next time. Rod is going to start charging us consultation fees if we keep this up.

But he isnt right now so im getting them in when I still can.

Push Rod

1) I regularly tow 12K with the TST on 5x5, and KSB1-2 non-wasted. This is about 425HP or so. EGTs will only get to 1400F when I stomp it right to the floor. The B1-04 will be a little cooler yet, so you should be just fine. I do use an RA3 though, versus your FIPK, but I think the it'll be a wash here and you'll see 1400F under a HARD pull in OD.

2) I don't really know the answer to this one. Don's injectors have been running cooler during his testing than the stockers, so I would say definitely. Do yourself a favor though, and stay away from the water/meth. Too many bad experiences with water/meth for me to recommend it to anyone.

Thanks for all your help and info Rod.
