Supercharger Performance and Engine Performance Parts

Hot Rod magazine brings us a no nonsense buildup of a street supercharged LS7 engine.

Alternative auto tech announces their new supercharger kit for the 2010 Camaro.

The kit is based on the eaton TVS (twin vortex system) with the new 4 lobe rotors and 160* lobe twist.

AAT hasn’t released much detailed info on what’s included in the kit… but we do know is that it does include the following:

• Eaton TVS 2300 supercharger top
• AAT custom short-ram style air intake with high flow cone air filter and heat shield
• Optional Borla Cat-Back Exhaust system

The combination boost engine performance by increase horsepower from 426 horsepower @ 5,900 rpm and 420 lb.-ft. @ 4,600 rpm up to 501 rear wheel horsepower and 455 wheel ft.lbs of torque.

Assuming a 17% drive train loss this gives us an estimated 600 crank hp and a calculated approximate 6psi of boost which is a very modest boost level for the Eaton TVS and does not warrant an intercooler for this application.

For people interested in even more power increases… Borla offers a complete exhaust solution including after-market high flow headers, an x-piped midsection as well as the cat-back exhaust.

All of these parts are available as an ‘installed’ turn-key 500whp package through AAT or as standalone parts for a ‘DIY’ install.

This is the first in a series of ’snapshots’ of a manufacturer’s superchargers that I plan on posting every so often. As you can see it’s written in simple English (in horsepower and boost) and is an easy way for people that don’t know how to read a compressor map to get a good idea of what their supercharger (or planned supercharger) is capable of.

Eaton’s first supercharger was released on the thunderbird back in 1989. Since then, Eaton has blessed the market with 5 generations of positive displacement, roots style superchargers with incremental changes between every generation and the previous.

 “The fifth generation Eaton supercharger or Gen V is the culmination of over 50 years of improvement to the original design for Roots superchargers. It features two three-lobe rotors, twisted 60 degrees and provides engine manufacturers with a proven, economical solution for adding power.”

After five successful generations of the M-Model supercharger. Eaton released a new version of their positive displacement supercharger called the TVS – Twin Vortices Series.

“The Eaton Twin Vortices Series™ or Eaton TVS™ is a patented supercharger design that features twin four-lobe rotors, twisted 160 degrees. By comparison, the original Eaton supercharger features three lobes twisted 60 degrees. The fourth lobe and added twist, when combined with redesigned air inlet and outlet ports, creates a smoother, more efficient flow of air into the engine. In addition to improved overall efficiency, the twin vortices Eaton Twin Vortices Series supercharger have improved noise and vibration characteristics as well.”

Building on the potent GT-500 plant, there are many possible ways of creating more horsepower, from basic bolt ons, to upgraded superchargers, to oversized motors… This is a great article by MM&FF showing three different power stages that are possible for your GT-500:

Stage 1:     JLT cold-air intake Single-blade throttle body Supercharger and crank overdrive pulleys Bassani axle-back race exhaust Everything else was left completely stock. Result 580 rear wheel horse power (rwhp). Stage 2: (In addition to the existing stage 1 upgrades) eaton TVS supercharger Afco heat exchanger. 2.6″ supercharger pulley 720 cc/min injectors Kenne Belle boost-a-pump Result 720 rwhp. Stage 3: 0.020″ overbore 9:1 compression ratio ford GT Supercar camshafts 3.4L whipple supercharger Result 800+ rwhp.

The 3.4L Whipple Supercharger crowns the power hungry 5.4L                             If this is what I think it is, you can see here a racer 'secret' modification. The four bolts in the center of the supercharger pulley break up the pulley into an inner sleeve and an outer ring, which allows for a quick change of supercharger gearing to change from low boost to high boost pulleys for race days, and then swap back easily back to a low boost pulley at the end of the race day. Very neat.
