I'm new to this site and like to introduce myself. My dad recently got a 99 GTS Viper. My specialty has been building V6 Mustang turbo kits for quite some time already. We decided to twin turbo the Dodge Viper!!!! I'm quite familiar with the Viper world, and know that the 99 would be a great platform for a poweradder as it has forged internals as opposed to the 2000-2002 cars.
I briefly looked at a few designs out there and im quite impressed with a lot of them. So I decide to make my own.
So here is some pics of my build up. Turbo headers and turbo position is pretty much finished.
I was looking at a few twin turbo Viper threads and I'm quite impressed by how much feedback and help the bigger turbo companies like Underground, Heffner, Hennesey etc. have been giving out. My hats off to them for sharing some great information.
Anyways here is the link to the pics of the buildup.
Yes this is my dads 2nd viper. We got it as a fixer upper from x2 collision hence the reason for the filth on the motor. I've already road raced this stock Viper at Thunderhill raceway, and it handles great. Only complaint is the braking ability and the lack of power in 4th gear. I don't think 4th gear won't be a problem for me with twin turbos
My dads 1st Viper is 2002 year gts and its clean!
As for pricing, I haven't run through the numbers yet on anything official but the ball park number im shooting for is 10k for the complete turbo kit no fuel/no tune.
Im no pro tuner so i rather not deal with that responsibility. Building turbo kits is my specalty so i'll focus on that.
I'll be done with the kit in about a month so i'll have more pics being updated. Hard part of the build is pretty much over.

Looks like your on your way to a good build. Your only setback will be getting the proper airflow to your snails. Like GTS Steveo said something about airfilters... get them!
The kit looks great, but you'll have to run the car without rocker panels!

The car will have the rocker panels utilized. The turbo exhuast outlet is positioned towards the area where the rocker panels are, and the exhaust piping is going to be ran in that location.
okay nevermind what i said u were just kidding. But in case for those that didn't know

i dont know what im looking at but it looks ok to me
My dad was very anal about having to trim anything. With an air to air unit you would have to start trimming the fiberglass/plastic off the front bumper planels stuff to make it fit.
The air/water unit is definetly more expensive then air/air but my dad wanted to go this route and have a much more simplified plumbing and shorter intake routing.
But ya the build is still pretty early on its stage, but everything will make more sence and be easier to visualize once i get more stuff finished.
FYI though, you might be carefull touting the advantages of not hacking and cutting... neither of my twin turbo street vipers have been hacked or cut... there are tuners out there who can do it. (ART, HEFFNER)
I like that you are thinking outside of the box though. That is what we need

Happen to have any pics of your setup? What size turbos are used on your kit? So they didn't have to hack away any parts of your front fascia with your air to air unit?
One thing I am proud of though is being able to stuff T4 turbos without having to hack away or get rid of stuff which is very hard to do with this large size of a turbo. Im also using dual 3" dumps all the way to mufflers. I haven't see a kit that I know of that offers a complete exhaust package without having to buy a catback. I am touting a 10k price range which is pretty competitive.
Im not trying to mass produce or take away bussiness from anyone. Nor am I trying to say my kit is better then yours type of deal. I give hats off to anyone producing a turbo kit for a viper as its very challenging. Im just building this one off kit for my dad and maybe couple more in the future for anyone interested. Im new to the viper world , but been around when it comes towards building turbo kits, so im just putting my foot in the door that i can build turbo kits just as good as heffner, underground, etc while doing something a little bit different.
But ya man I definetly would like to check out and see pics of your viper.

Since the bottom oil drain fitting if i drew a horizontal line it would hit the bottom oi oil pan area. If i used a gravity feed system it would have to climb a couple of inches and most likely wouldn't work.
So a scavenging oil pump would have to do with an oil resevoir and of couse the one way check valves the viper turbo kit manufactures were recommending.
All CPE kits have dumps offered in either 3 inch or 4 inch size, depending on downpipe.
BTW-- looks EXACTLY like the system Chris Johnson made for SW. Is that his old car?
Wow I didn't know there were that many people building kits for viper.
Thats good they are using 3" dumps. But is it a complete exhaust all the way to tailpipe? I don't see no mufflers or tailpipes on it. Thats cool that they are using big exhaust dump pipes but how far does it extend out to?
Well my dad got the car at x2 collision just a stock viper.
NOt sure who Chris Johnson is? Got a pic of his kit?
Its hard for me to critque the cpe turbo kit design b/c i can't visually see the layout and they don't include pics of their headers which I personally feel they should show if they seriously wish to market it out. Its the most important design aspect for a turbo kit.. Very hard to make a sell if your hiding the most important aspect of the kit.
The CPE kit plumbing looks excessive which is cool if it works it works but im taking the opposite approach. I do like their big turbos they are using. Only problem with using those huge turbos in my location is that the turbo compressor will hang low underneath the car and one small speed bump pretty much means cracked header. Reason why i opted for an "E" compressor cover since it sits flush with the frame.
Im sure a lot of trimming was needed to fit a cpe kit. Its definetly a very high hp potential making kit but that usually requires a lot trimming and cutting. Again not the same route im going with for my kit for my dads street viper.
