I am looking into getting a B1 bomber for my truck. I am a little worried about how much lag this thing is going to have. Does anyone have any experince with a TST pressure stack and this turbo. Which will cool better B1 Bomber or a HTB2 64, my EGTs are out of control.

I have the B-1 04 on my truck and spool up is awesome. I don't have any experience with the HTB2, but I highly reccomend the B-1. It cools way better than I expected from a single. I was worried about spoolup too as I have an automatic, but It spools up well even when I run it only on my injectors.

From what I can tell the B1-04's compressor wheel is 62mm in diameter.

Do you have the B-1 ex 4 for the hx 40 downpipe. I am looking at getting the biggest b-1 the got if it is going to be drivable. How hot does your truck get when the tst is cranked.

SLEDHEAD

That is exactly what I was told that my B-1 is, the biggest we have. I don't know what you mean by the "TST cranked" I have found that it pulls hardest on 5-3 (old program) anything over that and there is just more smoke, and power loss. On 5-3 temps are very controlled, 1300 on a 15psi launch 1/4 mile run. If I dial it up much higher the duration of the pulse is too long and there is a lot of smoke and less power. I don't tow heavily, 3,000-6500 lbs max. I have never had Egt problems pulling those weights.

I actually think the B1-04s spool just fine on stock power. About the same as the G1 I just took off. Easy to set over boost codes without the box turned on though.

SLEDHEAD,

What are your 1/4 mile times with the TST/DD3 combo?

You need to get a few pics in your gallery so we can drool over your lift.

SLEDHEAD

No time slips from the track, if that is what you mean, but there are a few D-maxs that are pretty sure that I'm fast enough. I would estimate low 13s, but this is purely a guess.
As to the pictures, I don't have access to a digital camera, so you will just have to use your imagination

thats what I say!! I want to see that lift !!!!!

SLEDHEAD

I will try to get ahold of a digital camera so I can post it.

That's the first I've heard of the TST losing power by being set higher. It almost sounds like your turbo can't deliver enough air to make more power, which is weird since you have an aftermarket turbo. I was under the impression that a TST could make much more power than stock transmissions could handle. I've never heard that running too rich limited power. Almost sounds like a blessing for folks who would turn it too high on stock trucks.

I know nothing about this firsthand, as my truck is essentially stock. I've been researching the TST box, as that's what I plan to use. If you can enlighten me about the running rich thing, I'd appreciate it.

SLEDHEAD

I lose power above a certain setting because, I am also running BIG injectors, and the Duration of the pulse is too long at the higher settings on the TST. I don't think that this happens on trucks with the TST only because of fuel delivery limitaions. (I also have a pusher pump) As for it being a blessing, I think not! That much exhaust gas can over speed your turbo causing failure, If your tranny lasts long enough

v8440

Oh, I see what you mean about the injectors. That raises ANOTHER question in my mind-people who want lots of power from their truck fairly routinely replace the injectors. If I understand you correctly, that can cause the TST to overfuel their truck and lose power because the TST does not know to compensate for the bigger injectors. My question is this: If this is true, is there some way to reprogram the TST to account for larger injectors? What about larger turbos? All else being equal, those ought to lean the motor out if the TST is fueling with a stock turbo in mind.

I know on replacement chips and ecm's for cars, many of them have options to get them reprogrammed for other aftermarket mods, like cams and heads. I just can't imagine that TST's box requires you to have an otherwise-stock setup to make max power.

cquestad

There are custom programs for the TST...

v8440...I am not sure what you mean about make power?

I bet Sledhead is 200+ over stock power levels. I consider that plenty of power.

v8440

What I meant was it seemed like the TST needs you to be stock to make max power (i.e. having the box turned all the way up). You just explained that to me when you said that other programs are available for the TST. I certainly didn't mean that his truck isn't making a lot of power. I have no clue myself on what his would make, but I'd bet it's a ton of extra power.
