Dynotuning Complete

(02/20/07) The results are astonishing. With boost limited to about 8psi, the dyno still measured 599 rwhp! For comparison purposes, the initial stock 405hp is now calculated to 713 HP at the engine. I calculate the trap speed is 131 mph. See Kennedy’s own page profiling this project.

(3/15/07) Finally the Buffalo weather cleared for just long enough for me to come get the ‘vette. I just barely outran the biggest snowstorm of the season.

Supercharging

With a ProCharger D-1SC installed by Kennedy’s Dynotune, the Corvette becomes a fire-spitting Corvettezilla.

Improving on the LS6

The following work was performed by Kennedy’s Dynotune, December 2006.
See this example of their handiwork.

ProCharger D-1SC tuner kit
Twin high flow intercoolers at 10lbs boost
Fuel injectors 42lbs with adapters
Fuel systems upgrade
Custom tuned on the dyno.

Supercharger Installed

(01/24/07) By today, the supercharger was installed. The dyno run (see inset) shows that the rear-wheel power rose from 362hp stock to 582 rwhp.

The ProCharger Corvette had 10 lbs boost. However, I talked it over with Bob Kennedy and we opted to go with 8 lbs boost, so it doesn’t generate quite as much power. We decided that we’d lean toward the side of safety. I’ll drive it around a year or so and we’ll revisit it again.

The Project

koset — Tue, 10 Oct 2006 12:00:30 +0000

It began life as a highly tuned, perfectly balanced wolf in wolf’s clothing. However, there’s always room for improvement. You can’t blame Chevy for not max’ing out all the horsepower possible from the LS6. As a mass producing manufacturer, they have to be conservative, which is a relative term here.

This gives us C5 afficianados a starting point to personalize and customize to our unique needs. For example, 1. more power, 2. highly tuned suspension, and 3. even more power.

Project Goals

600+ hp at the crank, 550+ rwhp Insane!
Qtr mile in 10 seconds? Or even 9?!!!
0-60 in 3.1 seconds. Chevy claims 3.9 stock.
Moderate practicality. Street drivability. Pump gas.
No exterior changes for now. It’ll be a sleeper.

These are the published performance specs from the Corvette Museum on the 2002 Corvette Z06.

Horsepower:	405 @ 6000 rpm
Torque (lb-ft):	400 @ 4800 rpm
0-60:	3.9 secs
1/4 mi:	12.4 secs at 116 mph
Drag:	0.29 Cd

These are actual measurements. The rear wheel horsepower and torque were done by Kennedy’s Dynotune on 12/18/06.

RWHP: 351
RWTQ: 357
Estimated hp transmission to the wheels (351 / 405) = factor of 87%
Only 13% hp lost through the drivetrain.

Lateral acceleration. See the Tire Rack skidpad shootout.

Skidpad: 1.080g
