The point is not that the TST box is at fault. Pressure boxes extend the amount of fuel that is injected as well.. Or add more fuel. Whatever. With the big TST box being the HP king so far...its just adding more fuel and heat than the rest of the bunch and failures are going to be more prevailent.

Most folks even though they are told not to exceed the capability of the turbos, do so anyway. If I had a box with higher levels I would be hard pressed to not use them. We all want to try them.

I have reports of the Common Rails running up to 1800 degrees before third gear

I think the B-1's are NOT wastegated as well. This would releave some of the boost and overspeed troubles.

JR, if you have a wastegate in place on your design this will of course help the overall stability and long term outlook of the turbo. Not to mention., if set up properly - reduce back pressure.

Heat is something we are all going to have to deal with on this engine until the development catches up.

Don the HX55 Hybrid's are wastegated. And are drop in replacements for HX40's.

........With the largest version on a 24v we did not have enough fuel to drive it hard enough to get past 1-1. (drive pressure VS. boost pressure)


J.R.

 

As everyone knows, I did not have good luck with either
of the B-1's (KS and regular housing) on my old 96' 12 valve!
To "keep the peace" I won't elaborate on that anymore!
But,.........I guess these failures a few of the members have had
is showing that maybe Ken D. is going to have to "go back to
the drawing board" to internally "beef-up" the current model
B-1's!

Don:

Great explanation on the turbos!

J.R.:

Glad to hear your HX-55 "Hybrids" are holding up well on
the newer trucks!

Again to summarize....if you want to use 9/9 on your TST PowerMaxCR...you can't. Because there is not appropriate Turbo being made that will work at that level.

We are assuming that you have intake, exhaust and transmission modifications appropriate for the mission, but we have no lift off because there is no available turbo. We are waiting for an aftermarket design and no currently available turbo will suffice.

Am I reading this correctly?

 

Soon there will be a HX55 hybrid (with a down pipe) that will be a bolt in deal for the third gen trucks.

J.R.

 

Sooooooooo, there is no single turbo currently on the market that will allow a PowerMaxCR to function at 9/9. The HX55 will fill the bill. Otherwise you will need twin turbos.

Is that the consensus conclusion to my question?

 

The TST CR box is somewhat of a race box.

Georgia Cracker,
You are absolutely correct.

You CANNOT Use 9/9 for extended amounts of time, without damage, on a stock motor.

This box is showing us the capabilities of the CR motor.

This box IS a godsend for those who want to run alot of HP, since there wasn't a box out before this that could add near the fuel that this box could to this motor.

This box comes on diferent than any other box available can.

Even on the 70HP setting, an EZ will feel MUCH weaker in comparison.

I don't feel that this box was designed to be "Politically Correct". The Edge COMP box for the 24V's (2nd Gen) trucks, was. You could put a COMP box on a 2nd Gen, crank it up to 5x5, and tow all day, everywhere without problems.

Now, the TST CR box is out, and people are EXPECTING the same thing,, crank it to 9/9, and tow all day,, no problems. The issue is, this box is stronger than anybody ever seriously expected.

Buy this box,, and run it on 4/4 or 5/5, and run it like that. parts wil last alot longer, and your Ram will have some good "get up-n-go"

Is this box Blowing stuff up? No. The box is "dumb", only doing what it was programmed to do. it takes X.X data in, and changes it to X....X.

Is this a "bad" box? No,, it's just turned up higher than some people realize,, they turn it to 9/9 and blow something up. Sure makes the box look bad by user error...

The problem is, this box is new, and is pumping it's full capability out. Soon, there wil be another TXT CR box out, that is not as strong, and this box will no longer be available. In other words,, TST is building a more "Politically correct" box.

That box won't be blowing stuff up. You might still be able to turn it up to 9/9, but it won't be the same as the current box.

We (J.R. and I) are in the process of getting a HX-55 on a 3rd Gen truck, that has the TST CR box, and 90HP injectors. This guy can blow up a B turbo on demand.

I'e asked a couple people about blowing up B turbo's on 3rd gens, and have been argued against sternly, that the B-1 won't blow up. Right now,, it's a gamble, and a possibiblity, that ANY turbo can blow up bolted to a 3rd gen.

Will the HX-55's hold? I'm confident they will. Wil they hold up, AND spool like a B turbo? MAYBE, but I do think they might have to be designed to be laggier, so they can be stronger.

This is all what I'm thinking,, The '55 may spool great and hold up, migt not.... Shoot,,,,, I don't even have a '55 bolted to a 3rd gen YET.

The '55 by design, is much better suited for the 3rd Gen trucks,, an area where only a few 2nd gen trucks were able to go. (insane spool-up (air flow), and insane fuel).
