With the TST box, ..what turbo upgrade?

[OT-OF-HERE!!]

With the TST box, what Turbo upgrade are members using? How much? Did they lower the EGTs? How much?

 

[SRadke]

There are still no singles that can accomidate the full fuel of the PMCR. DD as well as others are working on something bigger/better but it's not here yet. The DD Jammer or KSB1 will lower egt's but still won't keep things cool with the full fuel settings. There have been several KSB1 that have come apart now due to this box. I have heard of some HX-55 hybrid testing going on but seen no results yet.

This doesn't make sense to me. Why can the DD Jammer Turbo and/or the B1 be able to handle the fueling of a set of DDIII's and an EZ (~480HP) with no timing advancement and keep the EGT's in check, yet not be able to handle the fueling of the TST box (400-420HP) which advances the timing as well? Something is not adding up. From what I see, you'd be better off with a set of injectors and a pressure box for both HP gain and EGT control.

 

[SRadke]

That is the million dollar question. The answer is still out there somewhere. Part of it is due to the fact the the TST box seems to put up higher numbers than they advertise. All their testing was done witbthe stock turbo and exhaust so the number should climb up after those two issues are addressed. Peter at SBC said the only clutch he has that would totally hold this box is a dual disc. Does that sound like 400-420 hp? There are some twins systems that have been tested and are being tested and hopefully the answer as to why it runs so hot is coming.

It's not the peak power that hurts, it's the delivery of it.

Id say the TST on level 9 is more tha 400-402 with a KBS1. I bet its close to 500 easy. 2nd the power and torque comes on real early which kills clutches in both autos and standards. Oncei t hits thehp/ torque rises extremely fast. This is not good for keeping turbos togther or clucthes hooked up.

All righttttyyyyy then, help me through this thought process,... is this box only a good investment if a guy is willing to keep throwing alot of dollars at the rest of the engine and trans to get anywhere close to the capability it has? If the answer to that question is yes then let's try this one. What is the box,... tried and true that you can put on and without dumping tons of other upgrades get full use from without killing egts or boost? I'm not thinking competitive pulls or drags here but rather good enhanced power over stock that can fully be used also for towing at a 15k lb capacity. Thoughts pls.

 

[KLockliear]

OOH, I can't say it's good or bad... only seen one in action once and was just for a dyno run.



All I can say is how much power do you want? Tried and true 200+ gain to the wheels is available right now, with more in the works. Regardless of how you make the power, the support gear (gauges, exhaust, airbox, turbo, pusher pump, clutch/trans upgrades, etc) will all still have to be there.

its all about self control with the TST box until more trial and error testing gets done with diffrent tubos and other related parts. This box makes ALOT of power and is an excellent investment for what I bought it for, to go faster. As for towing with this box I cant say first hand yet, But a box with the adjustability and power that this one has I say its hard to go wrong. These trucks also run hot stock and even the smaller chips out there can easily push the EGT limit, so whos to say that those chips are any better or safer to run on our trucks?

 

[SClements]

I'm buying the TST... if I bought any other box I'd be tired of it in a week and wanting more power. If you can stand to run on lower setting while you bullet proof the rest of the truck, the TST is awesome because you can grow into it. I think with any of them you'll have to do other work elsewhere to control egt's and clutch slippage etc. The TST just sounds like the way to go for me.

I stand to be corrected but as I recall we have had reports of the PMCR shredding turbos at level 6 (of 9 possible levels)

They come on so hard and fast that the turbo just grenades.

There currently are no turbo upgrades for the 600 trucks.

Not until someone comes out with a fooler for the wastegate controller.

[SRadke]

As said above, SELF CONTROL! Leave it on the low settings and the power is strong, egt's are managable and it's a great box. The high settings are just too much without some other major upgrades.



Bob is correct, there was a report of a stock turbo blowing at setting 5. If this is the same case I read about he was using an EZ boost elbow which didn't allow the wastegate to open soon enough and the turbo spooled right off the chart.



I have towed with mine with great results. Setting 3:3 towing an aluminum trailer with a dozen 1100lb cows (I was a little overweight) I held direct on a 5. 5 percent grade @ 55 mph with EGT's at 1075. The intake and 4" helps to cool egt's a bit but that's good useable power.



If you want a box that is tried and true I'd have to say the EZ but if you want a capable box you can grow into the PMCR is a good choice. JMHO

how did this turn into another box debate???



HES LOOKING FOR TURBOS!!!

I bet it's more than 500, here is dyno chart with with level 6 making 491 hp . this turbo is great and it's hooked up to a pacbrake. also I have been towing level 5/5 around town with 14000 gcw and egt are below 1250.

 

[robertyoke]

I cant figure out how to compress file to fit under 32000 bytes well maybe I try later. the numbers were:

box on 5/5 472. 84 hp & 1007. 76 tq

box on 6/6 490. 95 hp & 963. 87 tq

the truck is starving for fuel and the higher numbers on the box made less hp & tq

 

[daytripper63]

Tell me more about this KSB-1 turbo

I ran 390hp and 879ft lbs yesterday on setting 6-5 and would like to cool EGTs a little.

Where can I get one,how much, and how much boost does it give?

What kind of EGT # on 6-6 did you have?

 

[robertyoke]

I got my ksb-1 from PDR (1-866-888-4159) other people sell them also but they have good reputation and were easy to deal with and Harry answered all my questions. I don't know how well this turbo will handle 9/9 'cause I cant get a the fuel up there (pusher pump is ordered) but i ran the box on 7/7 on the dyno egt were not the problem.

boost is at about 45 psi on level 6 and is not steady do to the lack of fuel. level 7 boost is 45 then 30 then 45 then 30... so on and so on. I saw a little of that on dyno also but easier to see on the highway

even on 5/5 I made 80 hp and almost 130#ft tq more than your truck and the egt's on the dyno were less than 1000deg.

wen I get pusher pump on I can give better reports on egt's and also how this turbo is at higher altitude than 5000 ft. for those who want to know.

this box is one of the first programs tst put out and will get reprogrammed soon it should have more timing advance and boost control ( this program ads fuel past 40 psi of boost the new program does not according to mark at tst). I just dont want to be without my box... it is too much

 

[BillGotthelf]

You talk about not enough fuel-why? Is it injectors or the box itself cutting fuel? Mine went back (I had one of the first boxes) to be reprogrammed. I loved towing (14000lb 5th wheel) with the box. I could actually pull away from traffic leaving lights and got 13. 7 avg with the box on 3/3 or 4/4. The box gave me 2 more mpg towing and 2. 3 more empty. I can't wait for a reliable turbo to handle the ability of this box.

 

[lmills]

definitely a lack of fuel flow. The box on settings as low as 6 can drop the pressure down to zero
