viper got manhandled

 

Duh, it's a race car.

 

motorwise it could very well be stock......500hp...hell they prolly even detune it after you factor in the power/weight ratio (obviously its going to be lighter than a production viper)

 

some info for you guys

World Challenge Car Facts:

Classes

Grand Touring (GT): Includes a variety of production displacements with no maximum. Forced induction is permitted and is used to equalize individual models. Sedans, coupes, convertibles and two-seat models are permitted. The cars can be rear-wheel, or all-wheel drive. Class horsepower range is 425-550 bhp.

Touring Car (TC): Cars up to 2.8-liters that are naturally aspirated are permitted. No turbo or supercharged engines. The cars can be front-wheel, rear-wheel, or all-wheel drive. The cars must be able to seat four adults, and convertibles are not allowed. Class horsepower range is 225-275 bhp.

Bodywork Modifications

Stock body panels may be lightened. Body panels must maintain stock profile, unless alternate panel is approved. Non-essential trim may be removed.

Grand Touring (GT): Hood, trunk/decklid and doors may be aftermarket composite components. Vented hoods may are approved on a car-by-car basis. Additional aftermarket composite components may be approved if deemed necessary to make a competitive package. Front splitter may protrude 2" from approved front fascia, but may be no wider than the tires at their widest point. Splitter may deviate vertically on the sides and bottom. The rear wing may be as wide as bodywork, or 72", whichever is less, excluding mirrors and fender flares/lips, with a maximum chord length of 12". Wicker bill size is free. Wing is mounted level with, or below, roofline.

Touring Car (TC): Hood and trunk/decklid may be aftermarket composite components. Front splitter may protrude 1.5" from approved front fascia, but may be no wider than the tires at their widest point. Only rear wings approved for the Touring Car class are permitted. The wings that are permitted are not more than 48" wide with a chord length of not more than 8.5". Wing is mounted at least 6" below roofline.

Chassis Modifications

Interior may be removed except dashboard. Miscellaneous unused mounting brackets may be removed. Chassis seams may be welded. Windows may be replaced with Lexan. Doors must be capable of being opened from inside and outside. Seats may be moved rearward as long as the seat back at the driver’s shoulders does not pass the vertical plane of the rear seat shelf. Windshield wipers may be removed, but an operational motor must remain in place.

Safety Modifications

A full rollcage must be used. The rollcages typically have eight main attachment points with additional tubes passing through the firewall and the A-pillar, B-pillar, and roof being stitch welded to the rollcage. Fuel cells are required, unless stock fuel tank is located between frame rails and the axles.

The driver’s safety equipment includes a racing seat, five or six-point harness, full-face helmet, head/neck restraint, window net, multi-layer suit, fire resistant shoes, gloves and underwear and a three-nozzle fire system.
Engine Modifications

Dry sump systems are permitted. Engines may be blueprinted and balanced. Engine management systems are free, but traction control is not permitted. Ignition system components may be replaced. Must maintain an operational on-board starter.

Grand Touring (GT): Forced induction is permitted and may be added to a car if deemed necessary to be a competitive package. Internals may be replaced with equivalent aftermarket parts. Noise limit is 110 dbA.

Touring Car (TC): Noise limit is 105 dbA.


Drivetrain Modifications

Transmission and differential coolers may be added. Limited-slip differentials are permitted. One set of gear ratios and two final drive ratios, or equivalent, are permitted. If the approved set of gear ratios is other than the stock set, the stock set of ratios may also be used. Clutch design is free. Flywheel weight is free, but must be steel or aluminum, and ring gear diameter must be stock.

Grand Touring (GT): Driveshafts and halfshafts are free. Alternate transmissions may be approved on a car-by-car basis if deemed necessary. Carbon clutches are permitted.

Touring Car (TC): Driveshafts and halfshafts may be modified or replaced, but must be same material and type as OEM. Alternate gear ratios and/or internals may be approved on a car-by-car basis if deemed necessary.

Suspension Modifications

The OEM-type of suspension must be retained (McPherson Strut, for example). The suspension pick-up points below the top of the tire may be relocated 25mm, and the suspension pick-up points above the tire may be relocated 75mm. Alternate control arms may be submitted for approval. Shocks and springs are free, but must remain in stock location. Anti-sway bars are free. Bushings are free. Steering geometry may be modified to correct bump steer due to lowering car to 3" minimum ride height.
Brake System Modifications

All World Challenge cars may replace the OEM brake system components with racing components. Carbon rotors are not permitted.

Grand Touring (GT): The maximum rotor size in GT is 355 mm x 33 mm. The OEM caliper, any 4-piston caliper, or approved 6-piston calipers may be used. ABS is permitted with a 100 lbs. penalty. Water may be injected into the brake ducts.

Touring Car (TC): The maximum rotor size in TC is 328 mm x 32 mm. The OEM caliper or any 4-piston caliper may be used. ABS is not permitted. Water may only be injected into the brake ducts on temporary street circuits.

Wheels

Grand Touring (GT): The wheel diameter used in the GT class is 18". The maximum wheel width is 10", 11", or 12" based on the tire size(s) permitted on each car. The wheel offset is free provided that the approved bodywork covers the portion of the tire that contacts the track.

Touring Car (TC): The wheel diameter used in the TC class is 17". The maximum wheel width is 8". The wheel offset is free provided that the approved bodywork covers the portion of the tire that contacts the track.

Tires

Grand Touring (GT): The tires used are the Toyo Proxes RA-1 race compound DOT-approved tire. The size(s) used depend on the GT car. The sizes used in the GT class are the 245/40/18, 275/35/18, 305/35/18 and 335/30/18.

Touring Car (TC): The tires used are the Toyo Proxes RA-1 race compound DOT-approved tire. The size used is the same for all TC cars, it is the 235/40/17.

 

So since they both run in GT than that means they are both within the 425-550 output range. The only thing that would make the difference would be handling, gear ratio, and how well the car can manage to keep the power to the ground at crucial moments. Much of this has to do with driver skill and tire selection. In the end the driver has to let the pit know if something isn't working right so it basically boils down to the driver skill being the grand equalizer.

 

yeah but still sick

 

i'm not surprised at all.. Skyline GTR is one of the best car ever come out of the land of the rising sun.
I have a video of the touge monster R34 being raped by a FD RX 7
the skyline had 600hp. the RX7 only 380ish:eek3:
they both have the same entry speed, but once enters, the R34 loose cuz cornering speed is too low.
even awd/aws can't save you when you're over weight h:

 

sexy. both cars a very nice

 

too bad you remove a fuse and you have a nice rw i should know i have one that and my civic are my babies and it is great for corners

 

:facepalm:
