L89 Corvette for 1967

May 7, 2023 by Pete

Lightweight aluminum cylinder heads were standard equipment on the top of the line L88 Corvette engine.  They were also available as an individual option on top of the L71 engine.
This option was available from 1967-1969 under the option code L89.

L89 Corvette for 1967

I discussed this aluminum head option in my 2017 annual issue of Corvette Legends, my softbound supplemental magazine.  My magazine was released at the Muscle Car and Corvette Nationals, MCACN, in 2017.  I also mailed it out to many of my customers who purchased a copy of my hardbound book.  Corvette Racing Legends, the story of the L88 option package.

L88 Corvette and L89 Corvette for 1967

I also discussed some horsepower ratings in this issue along with my previous issue from 2016 regarding the L72 Corvette engine option.  This was all printed several years ago in my publications.

Well apparently, now in 2023,  someone has decided to take some of my intellectual property and he or she is reprinting it claiming that it’s their own.  I am not being given credit for this information.  This L89 Corvette information was personally given to me from a retired engineer.

 

I am currently preparing my sequel to Corvette Racing Legends and it will contain an enormous amount of information that was not possible to print in my original hardbound book.  My second hardbound book will not only review my 1967 L89 Corvette technical information, but it will also include L89 technical information from 1968 and 1969.

  So when you want to real and complete truth about Corvette high performance, you can get it from my books.

I currently do not have an exact release date for my second book, but keep visiting this site for more up to date information regarding its availability.

2024 Corvette E-Ray

January 18, 2023 by Pete

2024 Corvette E-Ray: For its 70th Birthday, Chevrolet Gives the World an Electrified AWD Corvette

 

First-ever eAWD Corvette E-Ray uses an advanced electrified propulsion system in addition to its 6.2L LT2 Small Block V-8 enabling all-season performance and composure — and 0-60 mph in 2.5 seconds1

 

2024 Corvette E-Ray

 

Exactly 70 years after the Corvette debuted at Motorama in New York City, Chevrolet has returned to introduce the first-ever electrified Corvette with all-wheel-drive and a powerful 6.2L LT2 Small Block V-8, the 2024 E-Ray.
“In 1953, the enthusiastic reaction to the Chevrolet Corvette concept kicked off seven decades of passion, performance and American ingenuity,” said Mark Reuss, General Motors president. “E-Ray, as the first electrified, all-wheel-drive Corvette, takes it a step further and expands the promise of what Corvette can deliver.”
Developed to be the Corvette owners can arrive in anywhere, no matter the season, the new E-Ray — available in removeable roof coupe and hardtop convertible models — uses electrification to enhance the driving experience with intense straight-line performance and sure-footed grand touring capabilities that can only be achieved with eAWD.
E-Ray is also the only sports car pairing two separate propulsion systems to provide naturally aspirated V-8 power with electrified responsiveness powered by eAWD, making it one like none.
The E-Ray is the quickest production Corvette in history, clocking a 2.5-second 0-60 mph time1 before breezing through the quarter-mile in 10.5 seconds1.
“Corvettes must provide an exhilarating driving experience on backroads and tracks, and E-Ray nails it,” said Tadge Juechter, executive chief engineer, Corvette. “The electrification technology enhances the feeling of control in all conditions, adding an unexpected degree of composure.”
A near immediate feeling of thrust from low-end torque is core to the Corvette driving experience, and the E-Ray packs plenty of it. Power comes from the 6.2L LT2 Small Block V-8, putting 495 horsepower and 470 lb.-ft of torque to the rear axle. It is complemented by an electric motor that channels an additional 160 horsepower and 125 lb. ft. of torque through the front wheels via a 1.9 kWh battery pack which is located between the seats. In total, E-Ray produces a combined 655 horsepower from both the electric motor and Small Block V-8.

Creating its own lane

E-Ray’s intelligent eAWD system is constantly learning the road surface, seamlessly adapting to meet traction conditions and driver needs. During spirited driving and in low traction environments, E-Ray’s eAWD system applies additional power to the front wheels, helping to enhance vehicle stability.

There is no need for plug-in charging for the E-Ray’s battery system. The battery is charged via regenerative energy from coasting and braking, as well as during normal driving.

 

Additional features and technologies of the all-new E-Ray include:
  • Stealth Mode, an electric drive mode for the street, up to 45 MPH
  • New lightweight lithium-ion 12-volt battery that supports the LT2 V-8 engine’s stop/start functionality
  • Standard Brembo Carbon Ceramic brake system for optimal braking performance
  • Standard Magnetic Ride Control 4.0 with three distinct suspension settings
  • Staggered 20- and 21-inch wheels with Michelin Pilot Sport all-season tires. Michelin Pilot Sport 4S summer tires2 are available with an optional performance package
  • Low, wide stance with crafted body styling that is 3.6 inches wider overall than Stingray
  • Visceral sound experience that embodies the car’s dominating presence. The electric front motor works in harmony with the LT2 engine to create an invigorating sound
  • Enhanced roster of driver assistance technologies (shared with all 2024 Corvette models), including Lane Keep Assist with Lane Departure Warning3, Forward Collision Alert3 and Automatic Emergency Braking3.

 

Electrified propulsion details

The 2024 Corvette E-Ray’s electrified propulsion system provides exhilarating acceleration to power out of corners, and effortlessly complete passing maneuvers. It can also provide limited all-electric propulsion at the driver’s discretion upon startup.

 

E-Ray’s standard Active Fuel Management system uses the electric motor to extend 4-cylinder operation in various driving scenarios.
The amount of electric assist is tailored within each of the Corvette E-Ray’s six driver-selectable modes: Tour, Sport, Track, Weather, My Mode and Z-Mode. Drivers can also select Charge+ feature which maximizes the battery’s state of charge.
E-Ray Performance App on the infotainment system provides the driver with technical insights into how the propulsion system is operating. There are three primary display layouts:
  • Gauges (displays dynamic power output from electric motor and V8 engine)
  • Dyno (provides graph of power/torque across selectable time intervals)
  • Data (showcases electrical system performance and efficiency).
The Corvette E-Ray’s electric motor over the front axle is compact, preserving space in the front storage compartment.

Stealth Mode and tracking the E-Ray

The Corvette E-Ray’s two driver-initiated electric modes enable the car to travel under electric propulsion in certain conditions. The electric motor also optimizes track performance.
Stealth Mode enables all-electric driving, when selected at start-up, for a period of time before the engine turns on for normal driving. It is designed for quietly exiting a neighborhood, with a maximum speed of 45 mph. The engine automatically engages if the vehicle’s speed exceeds the limit, additional torque is requested by the driver, or the E-Ray’s battery pack is depleted.
When it comes to leveraging the electrified propulsion system for enhanced track performance, E-Ray’s eAWD control system applies torque to the front axle as needed. The Charge+ feature can be used to maximize battery state of charge for extended lapping.
The custom-designed Performance Traction Management (PTM) modes are optimized in concert with the eAWD propulsion system.

 

Distinguished design  

At a glance, the E-Ray shares its purposeful, wide-body proportions with the Z06, accommodating wide wheels that help manage the car’s greater torque delivery. The lightweight alloy wheels have a twisted five-spoke star design that is exclusive to E-Ray.
“There’s never been a Corvette like E-Ray and its sophisticated design reflects that,” said Phil Zak, executive design director, Global Chevrolet. “It starts with the body color trim which draws your full attention to the exotic proportions of the E-Ray. The interiors allow customers to reflect their individual personalities with their choice of color executions that provide a refined or dynamic sport look and feel.”
E-Ray design highlights include:
  • Four aluminum wheel finishes
  • Fourteen exterior color choices — including new for 2024 Riptide Blue, Seawolf Gray and Cacti
  • An E-Ray-exclusive body-length stripe package in Electric Blue
  • Standard carbon flash badging
  • Available black exhaust tips and bright badging
  • Available carbon fiber ground effects
  • Optional carbon fiber wheels in carbon flash, visible carbon fiber finish or visible carbon fiber with a red stripe

The E-Ray also introduces the all-new Artemis Dipped interior, which features complementary deep green tones on nearly every interior surface and will only be available on 2024 Corvettes. There are multiple options for customers to select when it comes to personalizing their E-Ray’s interior including two carbon fiber trim packages, three seat choices, seven interior colors, and more.
Additionally, there are new Charge+ and Stop/Start buttons on the console and updates to the infotainment system and instrument cluster aimed at providing a more integrated appearance.

Join a Corvette Club

September 2, 2022 by Pete

Join a Corvette Club

Why did I join a Corvette club? There are several reasons why I joined a club.  I will also include a few more reasons why you should join one too!  I’ve been a member of each of the two major Corvette club organizations.  After experiencing both, I’ve chosen to stay exclusively with the National Corvette Restorers Society, the NCRS.

 

I can share my interest and enjoyment of Corvettes with other members.

By sharing my enjoyment and interests, I will also hear about what experiences my fellow club members have gone through or enjoyed with their cars.

 

Technical help is there when you need it.

Having repairs done on your SUV or family car is usually not a problem for your repair center.  But when it comes to your Corvette, there is a great chance that your car was built ten to twenty years before your favorite auto technician was born.  Even with some of the C4 and C5 Corvettes, most mechanics were either in pre-school or they may not have been born when your Corvette was built.  As a result, your technician has never had the opportunity or the chance to work on your early LS1 or a Gen II LT1 engine.

 

Locating needed parts.

In today’s world, trying to locate and purchase a part for your car has turned into a challenge.  Only a few years ago, auto parts were abundant and easily obtainable. Now, they are out of stock and your favorite stores don’t know when your needed part will be back in inventory.
Most members of Corvette clubs are very well networked and personally have a small supply of hard to find parts.  The NCRS is networked with companied that specialize with Corvette parts. These companies are not located in your neighborhood.  They ship all across the country.

Improve the return on your investment.

By being a member of the NCRS, you are in a community of experienced Corvette owners and enthusiasts.  Many of these individuals have been members for thirty or more years.  Being around experience members who have focused their knowledge on correct fit and finish of Corvettes can help you assess your own Corvette, at your pace.  You can get a much better perspective of what correctly maintained Corvettes should or shouldn’t look like, run like, or sound like.

 

For those of you who are already members of the NCRS, if you haven’t already done so, PLEASE join your local Chapter.  We would love to hear your input and share your knowledge and experiences with all of us.

2022 Corvette NCRS Northwest

August 23, 2022 by Pete Leave a Comment

2022 Corvette Club

The 2022 Corvette NCRS Northwest Chapter held its regional meet on the third weekend of August this year.  It had a wonderful turn out of both participants and spectators.  It was held in Redmond Oregon, which can be considered as High Desert territory. Redmond is over 3000 feet above sea level. So it’s not as high as say Denver Colorado or Albuquerque New Mexico which are both over 5200 feet above sea level.  The mountainous terrain is a mainstay, so are forests, rivers, lakes, buttes, and a few snow capped mountains.

 

2022 Corvette Club

Several generations of Corvettes participated in this regional meet.  Here we find three 1966 Corvettes.

 

2022 Corvette Club

From left to right we have a blue 1971 Corvette powered by an LS5 454 engine that is bolted up to a 4-speed manual transmission. The yellow Corvette in the middle is a 1970 coupe that is optioned out with an LT1 350 solid lifter engine which is mated to a 4-speed transmission.  The blue 1970 Corvette on the right has a 350/350hp engine with a 4-speed transmission.  All three of these cars were being judged in the NCRS Top Flight category.  I had the honor of co-judging the interiors of these C3 Corvettes.

 

2022 Corvette Club

Although only a single model year separates these two Corvettes, they are distinctively styled with their own personalities.  The Corvette on the right is a 1967 model that is powered by an optional 427 cubic inch engine.  The Corvette on the left is a 1968 model with the Mako Shark show car inspired body style. The hood on the 1968 Corvette is not seen very often. Yes, that car is powered by an L88 engine!  I had the honor of co-judging the exterior of this L88 Corvette.

 

2022 Corvette Club

A row of very early model Corvettes participated. The yellow model is a 1955.

 

2022 Corvette Club

I singled this Corvette out as it is an early production 1956 Corvette.

 

2022 Corvette Club

Some later first generation Corvettes including some really nice blue examples from 1961.

 

2022 Corvette Club

It is a rarity to see a split window 1963 Corvette these days. Three split window coupes participated, and all three were white.

 

2022 Corvette Club

Categories exist for more current C4 and C5 Corvettes.

 

2022 Corvette Club

Even some of the Corvettes were driven to the show.  These cars had their own categories as well.

All in all, this event lasted over three days with participants from several states and Canada. The Redmond Oregon location was wonderful with various activities to be found when not at the meet. The knowledge that is shared and gained at meets such as this one is priceless.  If you own a Corvette, please consider joining the NCRS. You will thank yourself later. When you do join, don’t forget to let the NCRS know that Dr. Pete sent you.
