SS Viper

Is there any interest to read and see a few pics about our development of a SS/D Viper GTS?
The project took 8 years and we made the first test runs two weeks ago...

The Viper was bought december 2004 from a Microsoft Excecutive :-) I shipped it directly to Lamb to take measurements so we could get a 5-lug bolt pattern for the front hubs.

After several test and a lot of research they found out what could work and the Chassi was transported down to Phil Mandella...the work could begin. This was about January/February 2005. Phil and the guys dismantled the Viper and shipped all small parts to Sweden.

After the Chassi was cleaned out the fabrication could start.
The Viper have a quite rigid chassi original and with the complete cage/tubbing it is rock solid.

The fabrication work with the chassi took about 6 months. When ready the Viper was shipped to California Shipping to a container headed for Sweden!

Before making the chassie ready for paint we fabricated all sheet metal/cover plates etc. The body it self is in composite, but in some areas we had to use 2 mm aluminum to get realistic function and fit.

When that was done and we were sure everything fitted perfect it was time to prepare the Viper chassi for paint. We stripped everything and left was a bare skeleton...weight about 350kg (800lbs)

In march 2005 the engine development started. The initial plan was to have the engine done in 3 months...but it took years, many years to get it were we wanted it to be in performace.

The first mission was to find a V10 block that was straight and good enough for the project...I can promise you that all V10 blocks are not. The block received Darton sleves and landed at about 502Cui

Internals to the V10, nothing exotic, just standard American Super Stock parts :-)

The most challenging part of the engine build was the cylinder heads and the valvetrain. The heads alone took about 3 months of hard work to get them to flow at decent levels. To get there we had to go way offset on lifters and rockers, 3 different sets of custom made lifters/rockers were tested before we ended up with a functional set.

Next step was to design a plenum/intake that would work good with the two tiny Trottle houses that comes with a Generation 2 Viper. A long plenum, no dividers, no planes, only filled with injectors and fuel runners...the injectors were mounted in the center of the runner, inside the plenum.

This is how the plenum ended up looking. It works realy well above 4000rpm, but under 4000 it would have been impossible if we didnt have a fuel injected engine. To get the engine to work at low speed we had to remove 80% fuel at the rear cylinders and linear add fuel towards the front of engine (closer to trottle houses).
The guys who did the Dyno tuning in USA dind't bother to do that, so we spent two days in a chassie dyno to get the engine driveable...

JP, what type of power where you able to attain with the engine and where in the rpm range is it making its peak power.
