egts with tst???

[98slushbox]

put the Tst on my truck the other day. I am very very impressed with the power along with my charger. makes an awesome amount of hp but an awesome amount of heat along with it. just curious what everyone else running the tst is seeing out of theirs egt wise? have injectors setting in my garage ready to put in but kinda scared to see what the temps would be then. Not a problem now to pin the pyro. within two gears.

Mine will hit the box EGT limiter within seconds with no load at 6/6.

What is your limiter set at? Thanks.

Is your turbo the KSB1 for the third generation? What are you seeing for boost?

Well, I have a box on order so I have been doing some checking around after reading some of these posts on the outcome of this box. I am now wondering how I am going to harness the power of this box. I have spoke with two individual dealers that have both told me that the box comes on so hard and fast that a SBC CON FE won't hold it on level 9, if you would dare to run it on that level. They both told me that South Bend is working on a new clutch to hold the power.



Then comes the EGT issue. I was then told by the one dealer that he is running a TST and the EGTs are so high that the KSB-1-2 and the EGTs are off the charts in as little as 3 seconds. So now, if we are looking to control the EGTs we will need to find either a different turbo or go with twins. As far as I am concerned twins are out of the picture for now. I would love to have them, but it just seems to be a bit too much for now. The issue with the EGTs was also confirmed by the other dealer that I spoke to.



On a good note I was told that they think that the box is way under rated and puts out more power than advertised. He told me that I would have to try mine out for myself and be the judge.

if your EGT's are out of sight in seconds, it sounds too me that this box is way to hot for the street. "you wanna play, you gotta pay. " definitely a box you can build on though, if you got the cash...

Sounds to me like something isnt right here...



Just my 2 cents. .

I was curious to know... you say you have the B1 bomber? Have you towed with it yet? If so, what level can you tow with it? Is the full B1 Bomber different from a quickspool B1? I just wanted to know about the B1 because I have one on order. Just want to make sure it won't be a mistake. Thanks. -Robert

I had a lot of major concerns with the PMCR. After trying two modules I have since sent them both back for a refund. My problems arised mostly from my own lack of preparing for the module. I am still running a stock turbo/manifold.



When accelerating hard, my egts would reach 1800 in minimal time.

Mark and I also determined that the intense manifold pressure created by the Turbo was causing the valves to stick. BIG PROBLEM.



I understand that the above issues aren't the fault of the box or TST, but here were my reasons for returning the box.



1. The PMCR continually threw 3 different codes on my truck.

2. When decelerating, the engine would "knock" repeatedly. This knock was the ultimate reason I sent the boxes back. It was loud and very bothersome to me, not to mention I don't know what it was doing to my engine



I can definitely say that for a PROPERLY setup truck, the PMCR makes tremendous power. I would encourage anyone looking to install this box to make sure they have taken all steps necessary to FULLY enjoy the power provided.

Good question--1250*, since I have three devices (analog gauge, TST box, and TTM) attached to the same probe, and I wanted a little margin in case the combination threw the reading off. I'll eventually add a post-turbo probe for the TTM, and hopefully a second probe to separate the gauges. Not having installed the boost elbow may account for part of it, too.



Here's a more detailed post I made earlier:

I installed mine this morning, and immediately went out and put about 50 miles on it. It worked fine right off the bat, and no codes so far (fingers crossed).



Mine was shipped 9 Feb, SN 1060. My cam & crank sensor harness did not have the extra ground wire, but I do have the bt (box temp) display page.



I have a Scotty III, but have not installed the boost elbow yet. I was surprised to find that on 6/6 I could peg my 35 psi analog boost gauge, and the digital went to 41 psi. On 4/4 it stays more in the 28 psi range, but I've seen 31.



I can hit the EGT limiter within seconds on 6/6 (along with that 41 psi boost)--and this is unloaded, on level ground, at sea level!. 4/4 seems to stay in control much better.



It may be partially due to the lack of the boost elbow (as with the EGTs), but this thing makes SMOKE!!! Well, maybe not so On 6/6 even if I try to build boost slowly, if I hammer it I get MAJOR smoke (OK, I've never been able to make smoke before, so my assessment of it may be different than others'). It's enough that I wouldn't want to normally drive on that setting, because it's generated so easily. 5/5 makes a pretty good cloud, too, but not nearly as good/bad. 4/4 can make a small burst/haze, and so is probably the upper end of what I'd want to drive on day-to-day.



6/6 is the highest setting I've tried so far, and so far I haven't noticed any clutch slipping--but again, this is all unloaded, on level ground, at sea level. The high-speed governor and/or high-EGT box limiter are hit VERY QUICKLY on this setting

Since then, I have set the P0336 (crankshaft position sensor performance) a couple of times.

From what I have seen a good air filter system like the AFE or equivalent takes about 200 degrees off the top end. I still can't believe that you are getting egt's that high with a B1. I have noticed with the bigger turbos that the egt's go up fast but as the boost builds they come down. As for TST's claim of 400 rwhp I believe it, as for other manufacturers claims it reminds me of an old joke about 8 inches.

 

[98slushbox]

yeah i have the full B-1 bomber turbo. didnt bolt right up but we managed to get it to work. suppose to move a little more volume air i believe than the ks but has more lag. This thing runs awesome with the b-1, doesnt come on until about 2000 rpms, but when it does hold on. with 33's it trys breakin traction. egts sky rocket though. buries the 1600 pillar gauge if u dont watch it. havent towed with it yet. have injectors settin in the garage. is anyone running any with the tst. what r ur egts with inj?

 

[Lonestar]

I had DD 3's with my PMCR, but like I stated before, I never had an opportunity to test with a good turbo, so they just created more heat for the truck.

It sounds like you have a straight B-1. Can you clarify what you mean by coming on at 2000? TST cliams (and the charts show) the power comes on earlier than that, is it the boost that comes at 2000? It burries the pyro at what rpm and boost? Sorry for all the questions but I'm searching for the whole story.

EGT's sky rocket

98slushbox,



That doesn't seem right. With the B-1 I would think that you would not have a problem keeping it cool. If I am reading this right the only mod you had on your truck is the TST box correct? What boost numbers are you seeing? What setting are you running?

I could see if you had the kwik spool but with the B-1 I thought that thing flowed a lot more air than the KS.



Dan

 

[SRadke]

To add to Dan's question, what are you using for an intake system? Something must be choking or retarding that turbo.



-Scott

 

[98slushbox]

The charger lites or spools up at around 2000 rpms. there is alot of lag and thats whats causing the heat. im seeing 45 lbs. of boost at full throttle. It buries the pyro only when its to the floor. hopefully i can get a little more fuel down low so the charger will spool quicker and get the heat out.

 

[Digger]

98slushbox,

What setting do you have the TST box on? Is this the only mod you have on your truck?



Dan

 

[98slushbox]

I run the box usually up on 9hp and around 6 on the tq setting, but even on 5, 5 it still gets hot quickly. I am running the afe cold air kit so it should get plenty of air through it. That is the only fuel upgrade i have is the tst box. i am running 5 in. exhaust and the cold air kit, but thats it.

, 9hp/6 torq???



i stopped at 7/7 because that was enough for now, I cant imagine 9/9, it must be insane
