what's up, has not been any turbo talk lately. anyone have a kit developed yet. anyone do a custom kit? lets get some info!!!
newbie here but i know that sts [ststurbo.com] has a twin turbo kit making about 460 to 500hp i have a budy that has one on his car it is the prototype the car is awsome. no price on it yet but right around $4500 to $5000. the guys at sts have some gto's running in the 11's and a vette in the 9's just my 2cents
THOSE ARE NOT STOCK STS KITS they are modified kits and the cars they are on would run close to the times they run with the kits with no turbo at all the gto has good enough heads and cam that it should be a 11 second car all motor and the vete has a engine capable of mid tens at least probably low tens. the sts design is not very well engineered and nto very efeicent you would be better in every respect with a bolt on supercharger. less exspensive same type of power curve and less complicated plus no chance of water ingestion like the sts kit. the reason to GO turbo over a centri blower is the ultra fast boost response and the superior low end torque .. thats WHY you go turbo instead of a centri blower. the sts kit has horrible spool times and a power curve that looks just like a centri blower due to the turbo being mounted so far back. a centri kit would be a better investment if you want simple bolt on power .. if you want the ultimate then get a custom turbo kit built.
All he asked was if there a turbo kit so the only one out is sts as of now and that friends car if fast and has very little lag @ 9psi.
I am having a TT kit custom built for my 05. IT will have twin water cooled 67mm turbos, all stainless piping.
I've seem Mike's @ PowerHouse run and it's impressive. He has a kit coming out soon @ wwww.powerhouse411.com.
All my stuff is here just need to find time to fire up the welder which is a **** cause I am in the middle of revamping one house to live in, one house to sell, and still trying to get my business on track after the last Hurricane, did I mention my full time job? Thankfully Friday is my last day there !!!
I'm always amazed to read this kind of stuff. I've driven an 05 Mustang GT with the STS twin turbo kit and it delivers full boost at 2900 RPM. I've owned two centrifugal blower cars in the past, and I can tell you that at 2900 RPM I was lucky to see 1 lb. of boost, and I didn't get full boost till redline. That and I was always having to deal with trying to figure out ways to keep the belt from slipping in the upper RPM ranges. The STS kit flat out delivers more power and torque at lower RPM than a centrifugal blower. STS is also in the final stages of releasing a single turbo kit that will come in right around the same price point as the majority of the supercharger kits out there. I've also driven that car. It sounds absolutely amazing and the power is there. The fun factor is huge when driving this car. This is the kit I will have on my car as soon as it's available. I've come to the conclusion that anyone that knocks the STS system has never driven one.
i have driven the lt-1 based kits .. and they are dogs. also the first time you hit a low water crossing kiss your engine goodbye with that inlet haging down there waiting to suck up water.
I'm not trying to sell anyone, just giving you first hand experience with the Mustang kits. I have no experience with the LT1 kit, but, I've driven the two Mustang kits and they feel great to me coming from a 98 Vortech'd Cobra (460 rwhp), and an 04 Eaton'd Cobra (420 rwhp). The power comes on more subtly than the Eaton (or any roots blower) but it pulls consistantly and hard all the way to redline. I also comes on much quicker than the Vortech (or any centri blower), and it sounds absolutely amazing. The intake on the Mustang kit is also tucked way up there compared to the LT1 kit. You'd be very hard pressed to swamp it by driving through water. Anyway, I'm just glad the choice is there. I've looked at what's available for the 05 (Saleen, Procharger, Vortech) and I'm ready for something different so I am going with the turbo. Choices are good.
What about the turbo getting wet during hard driving. Is there any concern over cracked turbine housings? Seems like a great idea, but the water thing came to mind when I first saw the kit? Hmmm... I wonder?
I guess only time will tell. The kit is going on my daily driver and we get all kinds of crappy weather up here. BTW, I was able to experience first hand their new Corvette C6 kit today: http://www.ststurbo.com/c6_corvette Man that thing felt great and sounded amazing.
But what do you mean by LAG, the common mistake that it's where in the rpm range boost is made or the real reason of what happens after a STALL period, where the reduction in exhaust gas flow cases the turbo to reduce it's speed halting boost, this combined with any high pressure air trapped between the turbo and the TB (is a dump valve isn't being used) causes the impellar to stall. When the throttle is reapplied there will be a LAG time before the turbo is back upto speed again and producing boost. Such an event can happen at any point within the turbo's operation rpm range, such as 2500rpm - to red line. This is unaviodable on ANY turbo setup and only the use of ALS (anti-lag systems) such as the 'Bang-Bang' are able to totally eradicate it. Low boost, good turbo matching and dump valves all help to minimise this. The STS undoubtably suffers from this because it is a turbo setup NOT running ALS, but due to the location of the turbo in relation to the engine I can for see it being worse, as the exhaust gases have to travel further to the turbo and the pressurised intake air also then has to travel further back to the engine. And to top it all when I've spoken with STS on the subject they have deliberatly sidestepped the issue and for want of another phrase, they have totally avioded and deliberatly not answered 'specific' questions on this topic. Logically speaking, if it was not an issue then why would they dodge the questions concerning it? I admit, I've never been in an STS powered car (don't even know of any in the UK), but from the video's I seen of people running them it is clearly evident (sound and visual) that they suffer far more LAG than regular turbo setups.
as has been said before.. that guy has enough mods in his motor to run a low 11 all motor.. and the kit has been modified its not a stock sts kit etc. stick a properly designed kit on a STOCK gto and it will run mid tens. and make more power then that car does on a other wise STOCK car. it wont need ported heads cams and all the other work that guy has done. a properly setup kit on that car with his mods would put it in the mid nines with ease that is where we disagree on sts kits.. they do add power yes but a properly designed kit would have none of the draw backs of the sts kit ie no water ingestion issues no poorly deisgned oiling system requiring a pump to return the oil wich usualy drasticly shortens turbo oil seal life and much more power being made from the kit. if your going sts i would say in every way possible you would be better off with a belt drive supercharger kit. yes a sts kit can make power but it wont make nearly the power a real turbo kit will nor will it have the advantages a real turbo kit has so why go that route. all these "fast sts" cars are modified kits and cars that can run within a half second of the time they run with the kits without the kits installed.
You do realise that the majority of heat issues with FI are a direct result and by-product of compression? When you compress a gas it builds up heat, on a FI setup you typcially use an intercooler (IC) to reduce this and try and bring the intake air temperatures down towards ambiant. The STS kits don't even run an intercooler, another flaw in their design. Think of this way, have you ever used a C02 powered air gun or paint ball gun? As you fire off a few rounds the gas catridge/cylinder will become cold, maybe even frosted. This is a by-product of gas expansion. A turbocharger or supercharger is doing the opersit as it is compressing gas as oppossed to expanding it, thus the heat build up.
Forget it, Since i'm just saying that they systems are pretty good and can make power, but i don't have every little detail nailed down so everyone can be happy. Here are the clif notes. STS not so bad if done right. Like i said i've had people offer to drive me in their cars just to prove the system is good and can be in an everyday driver. I've seen excellent numbers from cars without Intercoolers and just the basic kit on a stock car. Maybe not the Mustang, but in general. I've seen better numbers with the intercooler and basic kit and i'm sure the owner feels much safer. I would never run without the intercooler, but some guys feel they can tune out any problems.
