STS Turbo System's, Yea or Nea?

[tyoneal]

To All:

Looking at different Turbo Charging possibilities. I wanted to get any information any of you have regarding the, "Squires Turbo Systems", single and Twin Turbo Charging Systems.

http://www.ststurbo.com

In a different post I asked about engine Builders for the Banks TT System. Well in a similar way what information do any of you have, Pro or Con with this System and/or Company?

It would seem this might be a good fit for Turbo Charging any of the LSx Engine platforms since many of the other systems are just for sbc's.

Any thoughts, experience directly or indirectly are welcome.

I'm looking forward to your post.

Thanks again for all of your efforts in answering my many questions.

Regards,

One thing I noticed is that in the dyno sheet for the ls1 it looks like it falls on its face after 5500 RPM. I have no experience with their setup and have never heard of the company before this thread. It sure seems like the people on this site that are running TWIN turbos are making a lot more power.

There are sts systems making HUGE power now. The front mount will make more power and have a massive bling factor. The rear mount has less clutter in the engine bay. The cost of both systems will be a wash. A typical front mount will make about 900 hp out of the box, a rear mount needs massive upgrades to make the same power, so in the end they cost about the same. A rear mount is also louder due to not having a muffler. You also lose dual exhaust unless you rig up a fake one or do dual rear mounts.

First off I don't claim to be a turbo expert at all. But you would think that putting the turbos way out back would lose the heat that the turbos run off of. The tail pipes get hot enough to burn you but not the 1500 degrees that you can get right out of the cylinder head at full power.

Do they run different impelars or something to compensate for the loss of heat or do they just not even holod acandle to under hood kits?

Good point, Rodger. From what I've read in books about turbo theory, it's the heat energy that spools the turbo, not the air moving through it. I would think you'd loose a lot of energy beteern the head and the rear of the car.

That said, there are plenty of people using the STS kit and making good power... but I don't know what type of lag they see. I would think that would be the biggest detriment.

[nitrorocket]

You are both correct, that is a huge factor. Typically a STS power curve is up higher due to more lag them a front mount. I also hear there is a noticable difference in spool and power with an sts, after the turbo gets hot it makes more power and spools faster. Most guys are getting the pipes coated and then wrap the snot out of them to keep all the heat in. If you are going to spend the money and want 800 hp, go front mount. similar cost, more power, more bling, more return value. I do not have first hand with a rear mount, but I have a ton with a front mount and am very happy with everything.

Nitrorocket:

What LS1 TT set up are you running?

We had a TT STS Vette in our shop. It was ok. It took forever to spool and while my boss was driving it the scavange pump blew a fuse. The didnt notice the huge cloud of smoke behind them until it was to late. COOKED BOTH THE TURBOS. Also with STS, I was not impressed with the fit and finish. Especially the tail pipes. Looked Terrible. I would go with the manifold mounted turbos. Much more heat energy is used and I personally think you get more bang for your buck.

I'm just a noob, but I remember seeing a tuner shootout in Motor Trend not too long ago titled, "Strike Force". I was really diggin the blue GTO by MTI with a 422(?) cu.in. and STS in the back. Went 193 mph in the standing mile, described as "uneventful" (which i think means "good" when you're going that fast.) Although I cannot answer for the oil control problems and quality issues. http://www.motortrend.com/multimedia...arison_videos/
