Viper Engine Build

[Lottie Dedinas]

The Viper engine is a high-performance naturally-aspirated pushrod 2 valves-per-cylinder 90 V10 engine designed by Chrysler but with aluminum block castings designed by Lamborghini for use in the Dodge Viper. Despite its large displacement, it is based on the Chrysler LA V8.[1]

The Viper V10 is based on the Chrysler LA engine family and appeared with the Dodge Viper in 1992. It was conceived and prototyped as a Magnum 5.9 with two extra cylinders and a longer stroke of 3.88 in (98.6 mm).

In addition, the Viper V10 was installed in the Dodge Ram SRT-10, earning the truck the Guinness World Record for fastest production truck (later bettered by the Australian Holden HSV Maloo, which uses the LS2, Corvette engine). The Dodge Tomahawk concept vehicle also uses this engine. Bitter Cars of Germany produced the Bitter GT1 based on the Lotus Elise GT1 using this engine.

The Viper is technically front-mid engine, as the engine is behind the front wheels. Where it differs from standard mid engine is its obviously in front of the driver, pushing the driver position back, rather than behind the driver, pushing the driver position forward.

It might have been a bit of a packaging nightmare, but everything needed to convert the engine from naturally aspirated to boost-fed were bolted in place and plumbed up. That includes the grille-mounted intercooler that has the job of keeping that intake air as cool as possible.

One of the coolest additions is the side-exit exhaust. The oh-so-sweet sounds and huge flames that erupt from the downturned pipe go a long way to show that this 242 is far from the sensible machine it rolled off the production line as.

Seeing that Joachim has a background in rallying, he went full WRC-style when it came to fabricating the rollcage. The 14-point cage ticks off the safety aspect while helping give a nice boost of rigidity to the 36-year-old chassis.

oldschoolcat I both agree and disagree with you at the same time. I agree that the interior and the exterior could be a little nicer, but then again this is a finished project. And when I get to finally some day get a garage and get to start a project it will propably look like something like this. Build a kickass engine and suspension that works well and go out and drive it.
I dont care so much about the looks of it as long as its absolutely mental to drive.

Just my two cents

Cool and hyper fun build but so little rear tire means this is just silly isn't it? I could roast wider setups of high performance tires with a stock'ish LS1T56 powered FC rx7. I mean I like this but I guess I wish there was more supersonic grip in the mix here.

oldschoolcat I think you just dont get it. Having a better car around this engine would be called buying a Doge Viper. This is whats awesome about it...it's a Volvo! A grocery getter!
On the whole too much power and cars not being made well. These are cars. Where would be if we stopped at 300 hp? The body kits also allow us to push the envelope speed (remember, the reason we like cars). You dont have to worry about bumping the wall. Now if a part gets damaged you can litterly bolt a new one on. No one is trying to go through the hours on body work knowing it could all be gone in a second.

I was wondering what was the bore ratio used to make it an 8.6l from the original 8.3l displacement.
Also where could one find the aforementioned "Ksport H-section connecting rods." I've been searching to find the sry but have cine up empty handed.

Fun fact: Flklypa grand prix, the old movie mentioned, is the movie that made our beloved Christian von Koenigsegg want to build cars. Not only did it make it's way into this ludacris volvo but also helped spark a dream that lead to the Agera, One:1, regera, ccx and every koenigsegg ever built.

Designed in 1948 as an expendable 7,006 N (1,575 lb) thrust turbojet for the Australian Jindivik target drone and still manufactured in the 1990s, this engine had one of the longest production runs of any turbojet. In 1952 the Viper 5 eliminated expendable features, giving the Royal Air Force the world's first all-through jet training system with the Jet Provosts. Uprated Viper 11's powered the majority of second generation trainer aircraft, such as Jet Provost Mark 4, Italian Macchi MB.326, Jogoslav SOKO Galeb, and Indian HAL HJT-16 Kiran.

The Viper 500, a Viper 11 derivation, was created for business, military trainer and light combat aircraft. The Mk. 601 series was the last having civilian application. In September 1973, this engine was installed on a Beechcraft-Hawker BH 125 Series 600A business aircraft, Ser. No. 256023, N514V. It was removed from service in April 1986 and donated to the National Air and Space Museum in October.

In 1992, under the tutelage of chairman Lee Iacocca, Dodge stunned the automotive world by unleashing a visceral brute of roadster reminiscent of classics like the AC Cobra. What most folks will remember about the Viper is its massive V10 engine, long maligned as a derivative of the truck motor that Dodge offered in its Ram pickups. However, the Viper's V10 engine actually predated the introduction of the V10 engines in Ram trucks by two years.

According to former Viper Powertrain Engineer Dick Winkles, the Viper's V10 shares far more DNA with Chrysler's "LA" engines, with two extra cylinders added for good measure. The LA engines are a series of tough small block V8s (think 318, 340, 360 cubic inch) that powered everything from muscle cars, to pickup trucks, to police cars for four decades.

By the time the second-generation Viper V10 launched in 1996, engineers had put the engine on a serious diet by trimming unnecessary material from the block and cylinder heads. Dodge also fitted a more aggressive camshaft and a new, less restrictive exhaust system.

The first-generation used an exhaust system which exited out the side of the vehicle, ahead of the rear wheels, serving as a modern take on the "side pipes" that graced vintage cars like the Shelby Cobra and older Corvettes. This side exhaust had to be very quiet due to the close proximity to the occupants' eardrums.

Engineers reckoned that if they relocated the exhaust exits to the rear of the car, a louder free-flowing exhaust would be permissible. So the Viper gained 50 horsepower, the V10 now belting out over 450 horsepower, but lost its distinctive side exhaust. Fortunately, the side pipes would make a triumphant return in the 2003 third-generation car, with the addition of a crossover pipe to keep the volume in check.

When the Viper was eventually discontinued in 2017, its V10 had grown in size from 8.0 to 8.4 liters. That, coupled with modern technology such as CNC-ported cylinder heads, variable valve timing, and architecture borrowed from the HEMI, resulted in 645 horsepower and a stump-pulling 600 pound-feet of torque for the Viper's swan song. The Viper's 0-60 MPH could now be covered in a scant 3.5 seconds.

Dodge's insane roadster will always be remembered for Chrysler engineers' bold move to stuff a ten-cylinder motor under its long sculpted hood. This modern muscle car relied on good ole' displacement to make horsepower, rather than forced induction like superchargers or turbochargers that are commonplace in today's performance cars.

The Viper can also be credited with playing a huge role in pulling Chrysler out of the doldrums and back into the muscle car fold, paving the way for exciting models like the Charger and Challenger. Just don't say that it has a truck motor.

Originally built for the Viper ACR-X, this beauty features forged pistons, under drive crank pulley, and A/C less front engine accessory drive (no A/C compressor included). No plug WIRES on motor. $219 for HiTemp booted wires.

OPTIONS: PartsRack had this motor dynoed, as a dyno-break-in performed at the factory facility in Detroiit for a cost of $995. It also includes a hard-shell CRATE value $250. The valve covers are set up for AN fittings as well, as found on the ACR-X. This new crate motor will make approximately 640 HP with headers.

NOTE: This is a brand-new Mopar Performance part. The photo illustration is a very close represent ation of what the actual motor will look like. Designed for high performance and racing, these parts do not carry a factory warranty. Email Jo...@PartsRack.com for actual pix.

At Velan Studios, we build and maintain our own engine and toolchain called Viper. Viper is the engine behind Knockout City and Mario Kart Live: Home Circuit. It includes standard things you might expect from any game engine such as a level editor, renderer, scripting language, etc. It also has less obvious components like network backend services and even a continuous integration system so Viper can build and test itself.

Removing barriers. As a small-ish team, we should be efficient generalists. We try really hard to make it so that a programmer familiar in one area of our code can be effective in other areas without having to learn some new third party library or language.
Using different tools to get different results. Our games are shaped by the tools we use to make them. If we want to make games that no one else is making, it helps to use technology that no one else is using.

Viper, and all the projects that use it, exist in a single Perforce depot. Most developers work directly on the main branch. We have a continuous integration system that builds and tests Viper on each of its 10 supported target platforms whenever a change is introduced.
