: Thoughts on remote turbo?

Anyone heard of Squire Turbo Systems (http://www.ststurbo.com/ram_hemi_dyno)?

Although they don't have anything specific to the GC SRT, they have developed a remote turbo for the Ram 1500 Hemi. Might not be *too* much to have them develop fo the GC.

Their solution seems to be considerably cheaper than others I see.

I have a problem with the air filter under the vehicle, 6-8" off the ground. It seems very "Puddle Friendly" in rainy weather.

It looks very interesting. They are offering snorkels & shields now for the water/dirt problems.

Looks a bit hokey to me,If i were going to go one I would get the one GSM has.Can't wait to see there #'s once they turn that thing up.:eek:

If you're going to do it (go turbo), do it right. Have you ever seen an OEM setup with the turbo hanging next to the rear bumper?

STS has a great product.. yes its not like others out there and it has its disadvantages and advantages but ease of instalation is amazing... yes i agree its better to have the turbo up in the engine but there kit is very impressive.. i figure for those who haven't checked it out do so before negative replies...

The dyno graphs for LSx and Modular motors look more like centrifugal blower curves than what you should get from a turbo.
The only advantage if you can call it that is the ease of installation. That much additional tubing will create lag and thermal loss (bad for velocity).

STS makes a good product and it seems to work well on GM products. I was their test mule for Ram SRT-10s. The truck was awesome. Just the sound alone was impressive. (You can hear and see the truck running at this link:http://homepage.mac.com/munoap/iMovieTheater1.html) However, the first engine blew after an unforseen closed loop situation when driving through some mountain passes. That was a software problem that was easily remedied. So, I had a "bullet proof" forged engine built specifically for running a turbo by one of the best Viper engine builders in the country. That engine lasted 1,000 miles before it lost the #3 rod bearing while being tuned on the dyno (most likely because of some serious detonation). That resulted in another 4 months for another engine rebuild. I had to replace all 10 custom made forged pistons, the #3 connecting rod (custom made too) and the crankshaft. Ever priced a V-10 crankshaft? OUCH!!!! I'm not putting down STS or their product. I can't even say that my engine failure was 100% caused by the turbo kit. It just got to a point where I couldn't sink any more money into trying to make the system work and I cut my losses. What I am saying is to make sure you find someone who really knows how to tune a Mopar PCM, I mean REALLY knows, and be very, very careful or you'll be spending a lot of money on engine rebuilds.

If you're still inclined to want to try and build your own turbo kit, I have a Garrett GTS 76 turbo for sale.

You cut right to the heart of the matter regardless of power-adder. It's ALL in the tune. Until we all have access to custom-tuning, power-adders are a bomb waiting to go off.

STS makes a very nice twin turbo kit for the C6 that comes with a Predator hand-held tuner and custom program that can be adjusted by the end user. STS claims a 1psi pressure drop in the system due to the rear-mounted turbos. STS also claims reduced intake temps due to the charge air cooling realised from the long tubing.

although i dont like the remote mounting turbos, but our 6.1L doesnt like that heat produced by the turbo near it. A remote Turbo will make sure to have less heat than any other.

plus, we keep hearing about GSM system !! Not a single person up to date has purchased thier kit. beisde those who installed it at GSM. Al though i heard that some guys in different forums have received thier kits !! but this fact was never been address by pics, HP, or anything.. even GSM themselves they dont give a clear statement. i believe they still running into issues!!

anyway, that was my thoughts :)

Some that know a lot more than me have speculated that the remote turbo allows for a cooler intake charge but it doesn't disapate heat from the cylinders nearly as well as an under hood set-up will and that could be part of the problem with cooked pistons. Again, do a lot of homework and be careful. I did and was and still lost two engines.

Sorry, I'm not following your logic. Underhood heat is a notorious power-robber. If the NA engine and exhaust manifolds remain the same, how would a remote-mounted intercooled turbo cause the cylinder to retain heat?
On the SRT10, were you running an EGT sensor? How about a wideband O2 sensor? What was your CR on the V10 motors that let go?

The higher the compression, the hotter the burn. The way I understand it is that turbos mounted near the heads act as a heat sink and help disapate some of the heat from the cylinders. The remote turbo doesn't have that benefit and therefore the pistons run at a higher temp. High temps and cast pistons with thin ring lands are a deadly combination. I did not have am EGT gauge but did have a wideband.

trust me, you need an EGT. even though your AFR are ok, you need to monitor the EGT. i have seen cars running 11.5:1 and thier EGT peeked up to RED zone

Ive installed a few systems from STS and id have to say its a great deal. You can install it yourself. Ive asked them if they had any plans to make a turbo setup for a GC and the answer was NO! Based on the amount of trucks being built and the small number of those willing to upgrade them, Its just no worth the time to r&d a kit. However they sell a starter system witch comes with the turbo set up and lenths of piping mandrel bent with random bends. If you can tig weld and cut pipe you could in a few days have a kit plumed. The major problem is tuning!!! Theres still not a cost effective way to due this. In a few months that may change?

Do you still have the turbo? My current 60-1 is to small so I want to replace it with the GTS 67.

A little off topic, but you can update your Jeep SRT8 0-60 to 4.6 seconds (as measured by Motor Trend.)

BTW, there was a shootout of cars, ome of which had an STS GTO in one of the magazines recently. The product is great, but placed at a very unorthodox location for a turbo (under the rear bumper). But hey, it's much cheaper this way, and the installation is much easier. It's also easier to work on, if you need to. Besides, you don't SEE it driving behind a car with this turbo. It's hidden. And does compression justice.

I've got a STS kit on my Vette. It rocks!
I picked the STS kit because of the sound.. umm... LOL

A STS kit on a Jeep SRT8 would be the mutt's nutts.

I have been talking to a guy in PR that bought two universal STS kits and made his Cherokke a TT. He is using a FAST stand alone though.

wow, twin turbo!! I LOVE that :D
i wonder how much tube he runs, I had TT on my previous V8 toyota, and it took me so much time, to re-design, and re-design the tubes to have less plumbing, but at the end, it was really GREAT.. it was a different world with TT.. i love TT setups cuz i know what it feels, i had 2 cars same engines same model, one single turbo and the other is TT, man, the TT is something beyond the single.. but again, its alot of work
How it would fit down there with so many tubes ? It would be heaven if SRT engineers have left us some space at the manifolds area to fabricate such system! IMO;)
