I think submerging a hot turbo in water is an all around bad idea, but I have a truck and four wheel drive so if I have to I can cross 3ft of water and be ok.

 

In my post I was trying to get across the point that it is very hard to get the turbo to suck up water, I drove throgh a flooded road at 35 mph, water went everywhere (Over the hood of the truck) I do not have the relocator kit just the sock. No water was found inside the filter or pipes.
The only con of the turbo under the truck is in your head, unless you submerge the turbo at wich point water is above your doors, you don't have to worry about it, and now with the relocator that comes with the kit the hole water thing can be put behind us.
Only one person on this board has had a STS kit suck up water, He had a bigger filter on the turbo and no sock or relocator kit.

 

if you drive through deep water your still going to get the engine bay wet too so it doesnt really matter where the turbo is mounted.

 

I ran my airfilter in the bed of my truck and havnt had any problems but then again i can run 54" tires. It keeps me high enough not to have to worry about it. I know when i ran the 12lbs of boost it ran like a raped ape. Not one diesel can keep up with it. With the intercooler and methonel 12lbs. shouldnt be a problem, at least i am hoping so. As any one heard anything bad about the stock duramax intercooler. It should bolt right in my truck beings it is an HD. I am also changing my STS kit. I am going to run dual 2 1/2 all the way back to the turbo with no cats and no muffler. Maybe it will help lower EGT's. Has any one heard anything on mounting the MAF sensor on the intake side instead of the boosted side. Some say it makes a big difference. Thanks for all the feedback.

 

that is awesome to have 54" tires and beat duramax's!! reminds me of my friends 81 chevy with 15" of lift 44 swamper boggers and brand new 502 ho crate. i thought no way would a truck with that big of tires be fast, but that thing will throw you in your seat and runs like a scalded dog.

 

I usually run the 44" boggers, the 54's are for shows. They are Titan tractor tires on 24" lexani's and they heavy as hell but still will haul ***.

 

The only problem I ever had with water was from a car wash with the high pressure water bar that goes all the way around the vehicle on a track from overhead.
When it got to the gap between the bed and cab it must have sprayed the high pressure water right into the air filter.
I don't have the relocation kit for the filter but am going to move it up or build something around it for this issue.
I have checked my filter many times from being paranoid about it after driving in rain, slush, through huge puddles and never had an issue then. Only once in the car wash was it an issue.
The other isues I've had were over boosting, the wastegate was freezing because of extremely low temps (10-25 degrees F) and the location of the wastegate on the earlier pipes that I have, and will be getting new design replacements.
Condensation from the exhaust was allowed to drain right into the wastegate on the earlier design pipes. This has been changed on the current versions.

OH ya, I did post about all of this before. Not trying to hide anything here.

 

TG02Z71, how would i know if i have the old style piping?, does sts replace it with a new one for free, i stiil have my kit under 1 year warranty, i got the kit last feburary, as far as the snorkel kit, they sold it to me at cost,40$ i believe, so you might want to check in to it.

 

I loved the STS on my Dodge. Plenty of pros, and of course a few cons ( like any other product ). I stopped posting on my STS because I was extremely tired of others hashing on my decision. Unless you paid the cash, you don't have a vote IMHO.
Sooooooo many people bang on the rear mount - water issue. ANYTHING is possible. I live in the middle of the desert and don't cross arroyos when water is running ( 2 times a year at best ) so it was a not a concern. The few times I went to TX or CO, the sock kept all water out of the intake system. I checked often when around water, no problem IF you use your head and choose a F/I system that is applicable to your driving habits.
I installed the STS and was driving in 5 hours. It was not properly tuned ( no proper way on the Dodge anyway ). Much, much easier than the SC installs I have witnessed. Deinstall took even less so going back to stock on a leased vehicle is easy.
AintNoHo is right, the STS or any turbo kit for that matter is not practical for serious off road use. A screw or Roots type SC gives you instant boost and power gains that would be preferred for those needs. The turbo was an ideal daily driver addition. I installed a low pressure WG spring and dual mode boost controller for a perfect his/hers setup. 3psi of boost is not too hairy for the wife, and 8psi had my grin ear to ear. In addition when the weather/traction was poor the truck was a ton easier to drive than it would have been with instant SC boost. Again this was a plus in my book whereas some prefer the SC performance. To each his own, just don't "bash" others for their choices especially if you did not spend your own hard earned cash on either!
The biggest con in my book ( also a plus tho ) is the ease of which you can increase the boost level on a turbo. Playing with the WG or installing a boost controller makes it all to easy to bump up the boost. This was my ultimate demise ( blown pistons ). I did not tune properly for the increase and paid the price. Changing a SC pulley requires a little more thought and altering the computer map usually comes with it. I believe this is why so many turbo owners lunch pistons compared to the SC folks.
My two cents, peace out everyone!

 

The snorkel kit comes standard with all new kits now. It has for quite sometime. The way its mounted on my truck, the filter is a little higher than it was when the truck was stock. I've had to cross some decent sized washes and I haven't had any issues. If the turbo is going to get quenched by the water, then it'll be in the cab too. I'm 2wd, so I have no offroading experience. I do run a max of 10psi, and no complaints. My IAT's back in october (+90*F) got up to around 135-ish. That was w/o an ic or meth. That won't fly though in the summer.

I can't think of any many real cons though. I haven't experienced any other than the fact that I think a few of the options should be standard items. I hear the same theories talked about ALL the time on this forum and on local forums, but personally I just haven't experienced them. I haven't put in a lot of ***-time lately, because I'm swapping to a T56, but I drove the wheels off the truck when I first got the kit. There are plenty of STS guys on here that divulge information. You have to ask though, we don't read minds.

As for your situation mac, you could easily run 12psi with forged pistons. Make sure you use good rod bolts and keep plenty of fuel to with some means of keeping IAT's down. I don't know what size engine you have, but the GT67 should be ok on a 5.3 at 12psi. With a 6.0 I'd like to see something a little bigger on there though.
