TT Pros/Cons?
Alright fellas(and ladies). I just got the ok from the wife:o to go ahead and do some more work on my C6. I was throwing around various ideas, Maggie, Procharger, 402, etc., when she asked me "What about the twin turbo thingy? I thought you always wanted a turbo vette?" She remembers me speaking of TT Vettes for years. She said, "I'd rather you not do anything but if you are going to do it at least try to get what you always wanted." So now I'd like to hear from those with a TT set up. How do you like your set up? How much power/boost are you running? What is stll stock and what has been beefed up? I'll be running a stock block and I don't want to have any issues. The car will be a DD(most of the time) so it has to be reliable. I'm aware most of my mods may need to be removed. Kooks, VR, possibly the cam and/or 4.10s(anyone running 4.10s w/TT?) I have a few months before this project can get underway so I have plenty of time to think, and research. Any info or advice would be appreciated.
Thanks
Thanks

TTix here
I've been down the Procharger road, & switched to TT's on previous C5Z.
I now have a '07 TT C6, A6 vert. TT cost more than SC but worth every penny.
Loose the 4.10s, 3.42s are plenty. On a stock motor (no cam etc) you will easily make 550-600rwhp with the proper tuner.
Go for what you've alwys wanted.
Good luck.
ps Your wife got any sisters

That was a consideration as well. At this point nothing is definate, i'm just doing as much research as I can. I have always wanted a TT vette. I'm not saying I wont be happy with a Procharger too but why spend all that money when for just a little more I could have what I always wanted? Like I said, I'm still deciding and price will be the most important variable. If I absolutely cannot afford the TT then S/C it will most likely be. All info is appreciated.

Time can change perspectives.
I really like TT, but I would not hesitate to go SC from guys like ECS and A&A.
They make plenty of power and are proven performers.
You really can't go wrong.
Just make sure you choose a kit based around your future hp goals.

you'll want it later!)

I have wanted a Corvette all my life and after years of saving I finally achieved that goal. A smaller side goal I had was a twin turbo'd vette. Something I figured was somewhat out of reach. The problem is when you reach one goal, you get greedy and want to achieve another. It never stops. So as of right now I'm just doing a lot of reading and researching to see how attainable it really is for me. I'm waiting on a few members, vendors, and tuner shops to get back to me. With all of their info I can then decide what/when to do. But any advice from any of you is more than appreciated.

A twin turbo package and exhaust work needed will cost considerably more money then a slap on procharger or maggie.
Now, I will ALSO say this. I NEVER built a corvette before but I have built my camaro (well, ex-camaro hence the screen name "upgrading"). I know the TT for the camaro is very expensive and the exhaust work is expensive too. Dont forget the constant tuning needed to keep up with this.
With a supercharger you tune.. your done. You might need a tweak here and there but with turbo's its a never ending tune.
Just my opinion.
Either way you go, you will have a KILLER package and I am very jealous.
Best wishes on your future build.

Reason you guys probably haven't heard to much of the TTiX kits for C6is because they just came out maybe a month or 2 months ago. If you are super interested in this I would highly suggest talking to Nick or George. They have been extremely patient with me about my set up and have been a pleasure to work with.
Also, you might want to go to the C5FI section. There is a lot of information there. Most of the guys have spent countless hours on their Corvettes.

you should get a TT setup and be done with the boosted question once and for all
with an S/C setup, there are always "what if" questions when you actually do run into someone with a TT setup
i've looked extensively at all the TT and S/C setups on the market, and came to the conclusion that anything over 550rwhp would require boost to be reliable and if boosted, that a TT setup is the way to go
amongst all the TT setups right now, if you don't mind the noise and the additional weight, the STS setup allows the use of GT-60's or T88's
it will allow you to keep your headers and still boost higher and cooler than any front mounted setup, and they have good customer service when compared against APS
i called APS and was told that my all forged engine setup was not going to make power with APS' smaller turbos due to low compression ratio (8.5C/R, forged internals, dry sumped)
for front mounted kits there's APS, TTiX, etc
i personally don't like the APS setups anyway due to the cast iron manifolds and the fact that they use silicone hoses everywhere extensively, i've always wondered that for 10k, can't they at least bend all the pipes needed?
and there are people who have had issues with early APS kits, though most of them have been worked out
but since i'm assuming that your engine is stock, so the APS kit might just work out
there aren't too many TTiX installs, so info is limited
also, something else you should llok at is an engine swap, an LS7 is around 11.5k or so, right in the neighborhood of the TT setup, and an all forged high C/R setup can be had for around the same or so, depending on components selected
though max safe power on a short deck block is somewhere around 550-600 rwhp, and anything over requires extensive valvetrain work, e.g. replace valvesprings every 5-10k miles or so
and a tall deck setup though will get you more power, will require custom brackets and headers at least, though you should proally talk to katech for that, i'm sure jason will sort out everything you might need

In my opinion there are really only 3 TT kits (to my knowledge). APS, STS, and TTI (listed alphabetically). The STS kit has very long pipes to the turbo, very long oil lines, and I haven't heard a lot of good feedback. The TTI kit (latest) is new, but the older kits needed a lot of manipulation according to sources I've talked to. Their new kits might kick butt, but I don't want to be a guinea pig. The APS kits have good feedback, if the tuner is capable. The only flack I've seen is in regards to their upgraded fuel supply package.
As for silicone piping, it is more than adequate unless you're running stupid amounts of boost. I run 21-23+ lbs of boost on my WRX and have the first APS FMIC (Type-R, yeah very Honda-esque) with nearly all silicone piping. I've never had one lick of trouble and have almost 6 years on the setup.
Iron manifolds are heavy, but they retain heat that allows gas to travel quickly. This is important in a turbocharged application. I'd prefer coated headers to save weight (which I have on my WRX), but APS has been very steadfast in this area and I have to think for a good reason.
I know this isn't going to go over well, but there are a lot of supercharger people that have or are switching to a TT setup. I've only been on this forum for a few months, and I've seen too many threads that say "SC making noise" or "Brand XXXX having problems". "Tighten the belt and reset the ECU" seem to be prevalent. QC seems to be an issue.
I'm not an APS poster boy. I just haven't seen anything else on the market (TT-wise) that looks like a contender.
I'm always open to argument (or discussion).

Thanks for all the info guys. The APS has been and still is at the top of my list. Their kit seems to be top quality and my tuner of choice is a dealer/installer.
I'm aware of all the other choices out there of comparible power and price, but I have always wanted a twin turbo vette. Max power is not necessarily my ultimate goal. I just don't want to spend $x,000 on something that's just as good and constantly be saying to myself, "Well for only a few thousand more I could have had what I always wanted." Like someone posted, "what if" So while I wont fully dismiss any info or advice anyone is willing to offer, I'm 95% set on a TT set up.....eventually.

I have the APS kit on my car, and I installed it myself for well under $10k last Spring. I like the kit so far, and I now have around 2500 trouble free miles on mine. It is more complex of an installation than a Vortech, Procharger or Magnusson, but it is quieter. You can read more about my install experiences with it, and see pics of my install on my web site. www.corvettediy.com You can easily get 500rwhp out of it, and can get up to 700rwhp out of it with tuning, alcohol injection, boost controllers, etc. I run mine at around 6.5psi right now, and run around 525rwhp and 535rwtq at that level. The only thing I'll say is that whether you go with a supercharger, or with turbos, be prepared to have minor problems at first, and then once you iron them out, you should be good for many miles. The initial problems you'll sometimes see with superchargers are with belts and pulleys, and with turbos, its usually oil leaks and air leaks.

Frankie,..I as well have heard many good things about the TTix turbos!
A good friend of Mine is having them installed on His Vette.
If the Turbo is what You want,..then only ask questions on that subject!!
You know Guys here get "pissy" sometimes!!
Hey,..I have a Maggie,and love it,..but "to each His own"!
Good luck My friend!!
