Hey guys , I am a proud new C5 owner, and I was interested in STS Twin Turbo Kit. Got a couple of questions maybe someone can answer.
What is the White cannister that says STS Turbocharged on it, is it for the oil return?? to be pumped back up to the front of the car. Also what kind of fuel management and upgrade does the kit come with? I was on STS's website and I could not locate the answer to these questions. Installation looks pretty simple i would say. Thanks for any help.

 

Yes, it is an oil pump. As far as the upgrades, right now you are getting 42lb injectors with the kit. That is the only upgrade that it comes with as far as fuel. I am upgrading them to 60 lb. injectors and also adding a new in tank pump and a BAP. You can alway tune a car down when running rich but it is not as easy when running lean so I am not taking a chance.

 

Everything he said is true, as for options, you can get quad tips (which I ordered) Methanol injection (which i ordered) and a dual stage electronic boost controller ( which i ordered) and from what i hear the kits will no londer come with a BOV as standared it will be an option, but i can be wrong on that one.

 

me too...

me too, from ECS

didn't get it yet but plan on getting the Greddy Profec

This is correct.

 

Cool , thanks for the help guys! Also I am just seeing 1 wastegate, does it just utilize one or two??

 

Sorry to sound dumb, what is a BAP? Thanks

 

BAP is the Kenne Bell Boost-A-Pump. It ups the voltage to your stock fuel pump to make it work a little harder when the boost is on

 

boost-a-pump, usually Kenne Bell.


Nevermind, his answer was better anyway.

 

One as far as I know. It works great with one. I saw Jason's car get dyno'd at MTI so I'm convinced it works just fine.

 

Would it not be better to get a Inline Pump , instead of something to make your existing pump work harder, what horsepower amount is our stock pumps good for??? And to get it right the STS kit does not include a BAP or new pump, NO BOV, and no ECU Management?? Thanks again for all the help guys!

 

-Not many Vettes are running inlines to my knowledge, I am not sure why. The BAP does work well though and has not caused problems for most people.
-BOV is not really needed on AT cars...must have on MT
-ECU Management in LSX motors is done thorugh ECM reprogramming. Look in the Scan and Tune section for more info on Tuning LSX motors.

 

I hate to be that guy that tells someone to run the search function butt.. Here is a thread that i started a while ago, but it got locked, oh well their is still a great wealth of information from when i was a little further in my decision making process than you. i was one of the first to place an order before the final system was even developed. Im glad i did when i did, i got a pretty kick *** deal

STS TT info

Good luck, and no you were wrong the kit comes with a programmer with the nessisary, very reworked then re worked again tune from STS and a few other tuners around the country!

All your questions will be answered.

 

From what I have read, the stock fuel system is capable of approximately 500HP depending on actual brake specific fuel consumption. Even though the STS kit hits 550hp on a stock setup, I will probably go a little further. I have opted for the Racetronix pump/wiring harness kit, which replaces the factory in-tank pump, and draws power directly from the alternator. I am also installing the MSD "boost-a-pump" product. I chose this after hearing that the Kenne Bell product merely switches high/low depending on demand, where the MSD will "ramp" up and down (theoretically preventing fuel pressure spikes when activated).

I got about half-way through my STS install, and decided that this would be the best time to upgrade. This kit is otherwise very, very complete. There is almost nothing that you need to provide but sweat and tools. I have really enjoyed this installation!


The kit includes a Predator ECM programmer. STS instructs you to read your current program, store it, and forward it to them. They will return a modified tune to get you up and running. From that point, you can elect to tune it further (or have it done for you).

 

A car like Jason's needs the extra waste gate LESS because he is using almost everything those turbos put out. The WG's bleed off excess boost (which he has very little of).

The guys that should be concerned about the missing WG are the guys who want to run low boost pressures or the guys that want to run larger than std. turbos. Since the engine won't be utilizing all the boost the WG's are needed to bleed off the extra boost... this is where you'll want the second WG.



Regarding the BOV, I can't believe they would not include this as std. equipment if nothing else just to cover their azzes regarding turbo warranties. When under boost and the throttle is closed the turbo is still spinning at very high speeds. The BOV releases the boost pressure and allows the turbine to free-wheel. If the BOV is not there the turbine goes into major surge (like hitting the wheel with a hammer) as the turbo goes from 90,000 rpm to 0 rpm in a fraction of a second... this is very destructive to the turbo over time to say the least!!! Not to mention without the BOV you also have to respool the turbo again each time you close the TB which is not good with a system which is noted for lag to begin with.

I can't believe STS is being so cheap by cutting a wastegate and making the BOV an option!!! I understand they are doing everything they can to remain competitive with the SC market, but they shouldn't be making necessary items optional. Like I said before, I'll be amazed if the new single turbo kit about to hit the market doesn't all but completely kill the STS business since it should perform better, cost a lot less, and come std. with all the required parts!

 

Thanks for all the help guys , this has been so very helpful!

 

No BOV in this system!

 

Dude, Come on, i know you are opinionated and speak straight foward, but dont try to promote one kit over another, its just not cool, but i agree, the waste gate thing and the bov thing is im glad i paid what i did when i did and got what i did standard.

 

This guy has done nothing but bash every STS thread on multiple forums and push his other kit (whats the name? I literally forgot.) on those threads. So I would say he is little biased. However, I do read his posts and try and always be cordial.

Navy08, there are lot guys out there that bought C5 STS kits. It would not surprise me that they will be coming out of the woodwork soon.

DDTSL5, good post.

 

what single turbo kit is coming out??
