Default Twin STS system for FBody?

caught wind of this on GMHTP ; http://blogs.gmhightechperformance.c...t-2/index.html

Apparently this is a fab up by Squires him self...

i'm assuming the Y pipe had to go and its setup more like the other twin kits they offer....

has anyone heard about this?

Really? I don't know why, but that seems like a lot of excess piping, but on the other hand, its makes the over all installation a breeze, with the kit being a remote bolt on & all. Do people usually run long tube headers with sts kits?

So they mostly stick with stock exhaust manifolds? I'm asking because I've actually embraced the STS design, and love the Twin Vette kits they make. I'm actually considering a twin-remote mount diy roughly designed off of a STS Vette system, it looks like it be very cost effective (south of $3K)

i think the reason for the lag is the choice turbo....

it really is, and I think that the diy twin rear mount, hell, a STS twin rear mount with 62mm turbos is not only cost effective, but just plain sexxy!

after you own one, you wont think so.

why i didnt like, where to start.

got water in my motor cuase sts said it was ok to drive it in the rain with there kit.

there oil pump went out and killed my turbo.( let me say it didnt go out. it just seemed to not flow as much oil as time went on.)

always hit pipes

went thought idk how many filters( the rubber from a burn out. just dont come off easy)

could only run one subframe connector. and i dont car how much sts did testing on it. that **** tube they use sisnt a good subframe tube.

___________________

no there was some good stuff. like i had a guy in a suit and tie lay down on ground to see turbo. that was funny

and it is unique, but it becomes a pain in the ***. had a biker whipe out behind me and slid under the car. in the process bent some tubes(now that isnt sts fault.) but if it was in engine bay. that wouldnt have happend.

i got a quick question. if you only got 3K, why do FI. i mean FI is avery expensive proccess. i got close to 25K in mine and still need fuel(grant i am shooting for 1000 horse)

i think you are right that you can do it for cheap. but FI and cheap dont go together. but if i was ever to do a rear mount again i would try and put it in my t-top spot. out of the ground area

I disagree. I had the GT67 with a .96 a/r, it did spool a little "slow" to me, but I could have bought the .81 version, but highway racing would have killed my power up top. I also had stock manifolds coated and wrapped all the way to the turbo. Also a better cam and it still spooled "slow" to me. But it made crazy power up top

I didn't have these problems, the only real idiotic problems I had were cleaning the filter EVERY month or it would get VERY dirty and my car was my DD back then, now it just sits in the garage collecting dust and parts til I have everything for my new set up

Right, should have explained what I meant. My understanding is the the higher AR, the slower it spools down low, which would explain the why it felt so slow to you. It also show why people like small twin vs. large singles... Did you have low compression heads?

Well, when I say 3K, I mean the turbo kit it self, I'm not including the suspension, tranny, forged internals and all the other things. The STS design is a good concept, as far as installation goes, I would personally have performance exhaust shop mount it. There's not such thing as the perfect power adder, and if there was, I think we'd all be pretty bored with it...

I think Big_Bird_WS6 is trying to tell you that you really need to read the sticky if you think that you'll get away with spending just 3K for a turbo setup:

Amen,

you will start with 3k, then it will jump to 4, then to 5k and before long you should ahve just bought a good setup or have that exhuast shop fab you up one under the hood

Big Bird & Pagreg ::

I hear you guys and I totaly agree with you, in the real world, it would be more than 3k, but how much more? Like I stated earlier, 3k would only cover the turbos and the piping. After that's, that's when I can realistically see a **** storm being created, but it still catches my eye. I personally know guy (a few of you may know him too) with an STS C6 Vette', His name is Greg and he and his brother run SmokinVette.com (his car was also on super cars exposed & jay leno's garage), after seeing the car in action, and really taking in the technology that's involved, I firmly believe it can be done.

I won't say it can be done, cheaply...but I will say it appears to be a gutsy solution to heat issues.

So turbos, inner cooler, waste gates, bov and piping fab = 3k give or take

Everything else = my first born..

And once again guys, I really like the input, keep it comming, its a learning experience for me!

I had a custom built one on my old Firebird, and I often scraped the ground with the charge pipe.

That is when I thought of this idea:

If you are going to run the charge pipe then what would be much better is to run it along the passenger side of the vehicle and make the bends com up through the right splash gaurd and wheel well. The pipes will NEVER scrape that way. There is just enough room to run the pipes that way. You can also get a 4 to 5 foot piece of Purosil hose to bend around the top of the wheel well. The piping should enter the intercooler from the right side of the vehicle and come all the way around to the driverside.

The twin setup is sweet.... I am sure that anybody can make the entire setup for way less than 3K includindg two turbos and the oil system..
