sts

Are you willing to gamble your engine that a tuner can save a poor design? You must have more money than most.
 
what do u suggest waste the almost 10 grand all put together for this thing or ask around for free advice. I guess a gamble is better than just throwing the turbo i n the garbace
 
You are right. Asking does not hurt.

The vast majority has told you the pitfalls. The STS system needs to be re-engineered in order to work reliably. There are no working STS systems that anyone has confidence in. Flyinglow has the last operating STS. And he heavily modified his. All that and he still does not come across as confident in the system.

So how much time, money, and heartache are you willing to invest in saving that 10 grand? That should be the question? At what point are you better off to walk away and start over? Only you can make that call.

I will tell you this though. Sympathy will be hard to come by if you decide to use the system after everyone has warned you of the bad reputation.

I wish you the best of luck. If you use the system, I hope you are the first person to make it work RIGHT.

You have a choice. You can either throw away the money you have invested in this piece of shit, or you can screw with it and then replace the engine.

The STS is not a normal turbo system, in that it uses back pressure to generate boost. True turbo systems use the expanding gases, not back pressure to generate their boost. And there is not a single god damn thing you can do to change that.

Sounds to me you have been on other sites looking for advice also, but don't like what you are hearing. So do what you want, as it seems to me that is what you are going to do. Just hope you have the money for a new engine.
 
You are looking for a solution that does not exist. You made the mistake by not researching...I find it hard to believe that you are not listening...

Keep the STS fool with it and blow the engine. You said that you have already bent a rod...what will it take for you to be convinced...we all make mistakes...your will cost you $10k or more if you keep trying to make it work.

Here is what I have told you before...go to a dealer trade your truck on a new one. Start from there...ask us and we will be very happy to help you in the process...or keep looking for the holy grail...you and Don Quixote can joust with all the windmills you want.

Care to explain the difference?

Bad info Mike.

The STS design is different. The plumbing is not done like the one 505 just did. The problem the STS had was at least 2 fold as I understood it. The tune in the program was not even uploaded in some of the early models. The second problem was one of overboost. In many applications the, the actual boost was much greater than the what the system thought. This was due again to the plumbing design. STS uses an auxiliary fuel injector. This route makes it difficult to meter the fuel curve. This lead to an uneven distribution of the fuel and air mixture. The # 3 cylinder is the result. In the successful systems the injectors are replaced with larger ones. The entire fuel system is used to augment the needs of the boost. The VEC 3 was used in the latest creation to control how much fuel was injected.

So the STS needs a lot more than just a tune. But hey it is not my engine. If he wants to experiment with a $10,000.00 (ebay) engine to save a few grand on a poor purchase, maybe Hennesey can install it for him.

Like I said, I don't know much about turbos, but would the first two items not be solvable with a proper tune and the third item with the larger injectors?

And don't give me any shit, you all!!! I want to understand the system and the reason it sucks (other than nobody knows how to make it work) there ain't a thing wrong with having a discussion about it.

MEmber #17xx..... go to search and type in STS... Grab a beer or a cup of coffee and read up...The STS has been beat to death and the only reason we bring it back is to prevent someone from getting and then blowing their engine. There have been folks with the resoures who tried to make it work and didnt. You will find all the info you need if you search on why it doesnt work with our v-10 motor.


Oh and to the guy who wants the sts to work. EVen if you do get it to work, It will still only run high 12's and make the cool sound before it goes out...You have been advised by several wise elders on the board already..(not me though)

No shi# here. When I spoke with RamFromHell, a victim of STS, he told of a condition of overboost. This had to do with the plumbing set up. The blow off valve was not seeing the same pressure as the intake manifold was seeing :dontknow: . But you are right, larger injectors will give the fuel system the ability to feed it. A tunable system will give it the brains to feed it. Of course neither of these come stock with the STS as it came with a unprogramable box that feeds auxiliary injectors.

The issue of backpressure verse the expanding gas energy is beyond me. Silverback is a engineer, and he has posted on this issue numerous times. You will have to search the board, as he is unlikely to take the time to say it again. As others have said, the board elders have turned there back on this system.

In the end boost is boost, as long as it is controlled and tuned. The STS has just not had either of these met, and many have tried. ALL OF THEM have ended in heart break or disappointment. The last time Flyinglow was posting about his STS, he was still worrying over it and trying to "patch" it. I do not think he ever got to the point that he trusted it.
 
hey fellas, the sts didnt come with injectors or a programable box. I bought a kit from performance injections equipment which was a smt6 box for the tuning. As far as the injectors i was told i didnt need them but after talking to sean from roe he said that i do and from listening to you guys it sounds like he is reliable. I was thinking of scrapping the smt6 contacting sean and seeing what he thinks. He said he had this kit on his shop truck and had a few problems but was able to fix them. like i said the kit didnt come with auxiliary injectors and now has 2 blow off valves to componsate for the over boost
 
Good luck. Like Ferrari said your only going to get in the 12's and high 12's at that with your sts. I wouldn't put it on my truck. Send it back and buy a paxton.
 
if i can get them to take it back i would rip that bitch off the truck tonight after i am done working 16 hours today,,,,, but i am still waiting to see if they accepted that option from me or not. I should be hearing something this week. In the mean time i thought i would get some friendly advice and it appears that some on here really arent that friendly and i am very sorry to all for bringing up a sore subject about the sts that you guys have been dealing with for awhile,,, sorry this is all new to me

You are mistaken on this one. This group is the most resourceful, knowledgeable, and friendly one around. Go to one of the Get To Gethers, and you will see that the members here are truly a group to regard. They will bend over backwards to help, when help is available. BUT, you must be willing to help yourself in order to get it.

When the help has been offered, and they feel you are blowing off the collective experience, the human tendency is to pull back the welcome matt. In this case, it was my feeling, that you really did not want to hear the nay sayers and prophets of doom just because you spent a lot of money already.

Good Luck.
 
We are usually a very friendly group. It's just that you brought up a subject that some have some really strong feelings about. Getting bit in the wallet can do that sometimes. Now if you really want to make friends, tell everyone your taking your truck to Henessey. There are even stronger feelings about that.
 
who the hell can afford to go to henessey???? I am only a registered nurse and i work to pay for the couple toys that i have, dont think i can squeexe the cash cow much more
 
That wasn't a recommendation. It was a warning. Some have been bitten in the wallet by him too. It's a good thing this thread isn't in the "offensive" area or you'd find out what people really think about him.

I doubt it. Others have gone through an engine or two on their own nickel. Don't know if you can hold STS liable or if they'll even admit to selling a faulty system. Probably just claim that it wasn't installed properly. Good luck.
