Project Viper GTS: Part 4 – Baseline Dyno and K&N Intake Test

Black car fuel cellThe fuel cell is an ice cell from TIG Vision, which uses a Rule 2000 pump and 1 inch feed lines.

Blue Supercharged PBH CarPBH works closely with industry performance leaders like Lethal Performance, Revan Racing, and Lund Racing.  This 2015 Mustang GT is equipped with a massive Whipple supercharger tuned by Lund Racing.  This collaboration is pushing the limit of what the stock 5.0L engine can take with off the shelf performance parts.  To date it has gone down the ¼ mile in the mid 10’s with sights set of 9s before going deeper into the build.


Viper History Lesson 2.0

In Part 1 History & Intro of Project Viper, we discussed the Viper’s creation, yet only touched on a few aspects of the Gen 2 1996-2002 cars.

We mentioned that the Gen 2’s lost their iconic side exhausts and lightened the 8.0L aluminum V10 by 80lbs (for a total of 650lbs) by revising the cylinder heads, camshaft, and engine block and increasing the output by 35hp to total 450 horsepower and 490lb-ft of torque (up from 415 and 488lbs respectively), but there were a few more changes throughout the second generation:

1996 GTS & 1997 RT/10: Introduction of Dual Front airbags.

1996: The only color option for the GTS was Blue with White Stripes (B&W).  RT/10 had: White, Black, and Red.

1996: GTS Stripes were ¼” wider (8.25”) than the 97+ cars, had a narrower gap between them (3 15/16” vs 4 7/16”) and the stripe ran through license plate area while 97+ cars did not.

1996:  2pc door seal and various engine seals (manifold, rear main) are more prone to leaking than 97+ cars.

1997: Better once piece door seal and main seals and intake manifold gaskets.

1997: RT/10 finally receives the same 450hp engine that debut in the 1996 GTS.



1996-2002: Brembo 38mm/42mm front Caliper.

1996-2000: Viper 36mm single piston rear caliper (Rear caliper from a Lotus Elise and Lotus Esprit).

2001-2002: ABS introduced and a larger 43mm single piston rear caliper.



1996 & Early 1997: 2pc welded cast wheels which are prone to cracking and are not polished.

1997 Late Model: Forged polished 17” wheels.

1999: 18” wheels are introduced.



1996-1999: Forged Pistons “708” cam which is known for its lumpy idle.

2000-2002: Known as “Creampuff Engines” use cast “hypereutectic” alloy pistons made with a special melting process to ‘supersatuate’ the aluminum with additional silicon content, producing a very hard and brittle piston.  These pistons have less thermal expansion, tighter tolerances, better emissions and many believe all of this results in a more powerful motor, although data shows that early Gen 2’s tend to dyno 10-20whp higher.

2000:2002: Utilize different lifters for smoother idle.



96-97: 0.541” lift & 66.0* overlap.  114* lobe separation.

98-99: 0.542” lift & 66.0* overlap.

00-02: 0.542” lift & 60.0* overlap.  120.5* lobe separation.



1998: 100 Championship-Edition Viper GT2 cars were produced, pumping out 460hp.

1999: Viper ACR introduced with race-inspired harness’ and suspension.

1999: Power Windows, textured dash, and better radiator fan.


17,949 – Vipers were produced from 1992-2002.

11,123 – were Gen 2 cars.

7,936 – were GTS/ACR Coupes.

2,128 – were B&W.
