Mmmm engine cutaway

[viper GTS-R]

Four months later, I'm still finding photos to edit from VOI. It's also 1:30 AM, but this is to good not to share.

Great picture!!!

I think the compression will be a little low in those cylinders! I know there's weight savings to be had, but that's a little extreme

The rockers look a lot like the GM LS ones

LOL... also easier to work on.

Nice shot .

 

[denniskgb]

is this for real?

Yes this is the new GTS-R Engine, SRT has had to cut down on power output for the 2013 American Le mans series and the 24 Hours of Le mans

•Engine size is reduced to 8 Liters by changing cylinder bore and stroke
Maximum engine size is 5.5 Liters, but the governing bodies allowed the 8-liter Viper V-10, requiring a restrictor in the engine’s intake tract
••A new intake manifold is created to work with the restrictor
•The engine will run on E-85 — 85% ethanol
•Transmission is moved to the rear of the car and will be sourced from Xtrac
•Dry weight of the car is reduced, with rules defining minimum weight as 1245 Kilos, 2740 lbs. dry
•A new roll cage is incorporated
•Bodywork is carbon fiber composite, with aerodynamic changes (body sides are lowered and front splitter/rear airfoil incorporated)
•New front and rear suspension systems designed to work with Michelin racing slicks
•Front and rear track increased
•Car has a climate-controlled cockpit, as required by the rules to keep the driver cool

" Bejnarowicz reported. "It is prettyDesigned for ALMS and Le Mans
On the engine side, SRT Chief Powertrain Engineer Richard Winkles will oversee the program with Roush Industries of Livonia, Michigan, SRT’s strategic partner. Le Mans and ALMS rules limit engine size to 5.5 liters "To achieve this we have lightened the engine and reduced capacity by cutting holes in it"

Yeah, but you won't find a better flowing intake/exhaust.

Oh Yes, VERY INGENOUS

But the GTS-R doesnt need an engine beauty cover or heat shields on stock exhaust manifolds.

Yea, but the French don't know that
