:: Dave's story :: |
I
took delivery of my 2003 Z06 Corvette on December 8th, 2003. I
waited for 5 weeks to get the
car from New Jersey to Hawaii and
the anticipation was too much. I had $5k worth of parts sitting
on the garage floor by the time
the Z came home. Halltech Candy Pomegranate Carbon Fiber
TRAP and Fuel Rail Covers with
custom C5 & Z06 Holograms, B&B Bullets, Hurst Billet Shifter, Z06
Screens for the whole car, Frame &
Rail Savers, Aluminum Gauge Bezels, Euro Red/Clear lenses,
Shortened Antenna, Goodridge
Stainless Steel Brake Lines, Optima Redtop, 18/19” Z06
Motorsport Wheels wrapped in
Yokohama AVS Sports.
I was able to enjoy the first round of modifications for a few
months; while slowly feeding the
mod urge with C5R Stage II HID projectors from Spectrewerkes, PIAA 1100x
driving lights, brake
light red Corvette lettering for
the rear fascia, 35% black tint, Vette Essentials shift & brake
boots, and a 2” drop on the stock suspension hardware, and J2 Concepts
Carbon Fiber brake
duct covers. By June of 2004 I had solidified a sponsorship from iForged
and my 18x10”
& 19x11” 3 piece Aero’s were being constructed. Working with Vince at
iForged netted me a
brand new finish from them in the form of a flat black powdercoat dubbed
Hyperblack. I coupled
the new wheels with some sticky
Pirelli PZero Rosso tires in 275/35-18 & 305/30-19 sizes. Then
came Phase II….
October of 2004 rang in the start for the Phase II build up of my
Z06 and we were completed with
all of the modifications by
November 2004. I wanted 500 reliable wheel horsepower, with rock
solid handling aimed at road course racing. I locked down a sponsorship
with Magnusson
Superchargers and my intercooled
and polished MP112 Magnacharger was on its’ way. I would
need a new hood to cover the
blower so a call to West Coast Corvette had me scheduled to
receive my Motor City Mold Carbon
Fiber hood in about 4 weeks. To compliment the blower, I
ordered some LG Motorsports
longtube headers with Random Tech cats and an 02 bung for a
Wideband Commander meter. To
monitor the vitals, Autometer Cobalt Fuel Pressure and
Vac/Boost gauges were seated in a
custom fabbed dual gauge pillar pod with a Raptor LED
shiftlite. To make sure the combo
was running to its potential I acquired the HP Tuners VCM
Suite programming/logging software. Now that the performance items were
accounted for, I
needed to address the need for
cornering horsepower…..enter LG Motorsports Coil-Overs and
Hotchkis Swaybars. The last items
on the list for Phase II were for aesthetics, so in addition to
the looks like MCM Hood would get, I cut out the stock hood for a change
of scenery between
shows and cruising. I incorporated
ACI front canards to the exterior, and custom designed EFI
Unlimited Fuel Rail Covers for the
engine compartment as well as a 175 amp chromed alternator.
With Phase II completed I am looking to complete all of the fine
tuning with the programming
and suspension. 2005 should bring new dyno & track #’s as well as a
bunch of new mods that
include, but are not limited to: a
Big Brake set-up, Carvaggio Race Style Seats, Carvaggio Side
Splitters, and a Spectrewerkes
Rear Fascia for looks. In the go department, I’m planning on a
Reichard Mag pulley to up boost
and eliminate any belt slipping, as well as a Meth/Alcohol
injection kit from ECS & Alky
Control. I will also be working with TKO Perfomance on a dry
carbon
fiber package for parts
replacement and aesthetics.
A huge thanks goes out to all of my sponsors: iForged Performance
Alloy’s, Magnusson
Superchargers, JL Autobody Works,
Island Car Audio, and EFI Design. Also a very special thanks
to my girlfriend Shane-nah for
putting up with my unrelenting urge to spend ridiculous amounts
of money on my OTHER obsession, and to the members of our car club-EFI
Unlimited who have
helped and supported the build-up
all the way!
