Listen if it’s a Corvette and you want to make it go faster…I’m fine with that. Who cares, why you want to make it go faster?

What would possess someone to create a Corvette with over 2,200 horsepower? Does it really matter? With an amazing feat like that, we didn’t think so. Take a look at the unbelievable Top Speed C5 Z06 that has over three times the amount of horsepower as a modern ZR1 at the April Ohio Mile event in the Wyldfantasies Media Studios video above.
Built by Hinson Motorsports, “Record Hunter” is among the most powerful Corvettes we’ve ever seen and there’s reason for that. Bringing the car to its astounding 2,246 HP rating at 7,800 RPM is a massive build the crew completed back in March.
Under the car’s hood you’ll find a 427 cubic inch RHS Aluminum Tall Deck Block assembled and machined by Butler Performance. Stuffed inside this block are aluminum connecting rods, Diamond pistons and a Callies Ultra Center Counter Weight Billet Camshaft, as well as a custom high capacity oil pan from Doug Lee Engineuity.
Making up the engine’s top end are TEA-ported Trick Flow 245cc heads, Crower roller rocker arms, COMP Cam pushrods, a custom COMP solid roller camshaft and a GM EFI carb-style intake manifold. But these components alone aren’t what gives Record Hunter its massive amount of horsepower.
That extra boost comes from an intricate custom turbocharger system featuring a 118mm turbo, custom air to water intercooler, Tial wastegate and blow off valves, and a 5-inch downpipe all working to the tune of 34 PSI manifold pressure.
Of course, a build like this makes for extra fuel needs, which the team has dialed in using a Holley Dominator EFI system and Bosch 160 pound-per-hour injectors, as well as a regulator and fuel pumps from Fuelab.
The whole build is backed by a RPM-built TR6060 transmission with a SPEC twin disc clutch and an RPM ZR1 differential with Quaife LSD.
Surprisingly, the Corvette looks relatively like the C5 production car it started out as, minus the modified hood, roll cage and custom adjustable rear wing, of course. But obviously, looks can be deceiving. And 18-inch wheels from True Forged Wheels wrapped in Hoosier R6 rubber make sure that as much of Record Hunter’s power as possible is delivered successfully to the ground to turn heads like no other C5 can do.
After completing the build in March, the Hinson Motorsports crew took Record Hunter to the Ohio Mile, an East Coast Timing Association event in Wilmington, Ohio on April 29th to see what it could do. As the first standing mile event the Corvette raced at since its build, the April Ohio Mile proved to be a great tuning opportunity for the crew since the mile race was speed-limited to 150 MPH.
It may not look too far off from stock, but Record Hunter packs nearly 2,000 more horsepower than a stock C5 Z06.
As the car’s name suggests, future goals for Record Hunter are to set new standing mile records. With a car potentially capable of topping out at over 250 MPH, we’re sure Hinson Motorsports will be making history with the car this season. Be sure to watch out for Record Hunter at any of the standing mile events this year. To check out some in-car footage of the first standing mile pass the Corvette did since its build, watch the video below.
I ran across on ton http://www.corvettereport.com and thought I pass it along. If only they made some of these!!! You got to check out the 1991 C4 body.
Hot rodder Shinoda teams up with Bill Mitchell and defined the “Corvette look.”
Perhaps it was “in the stars” that Larry Shinoda was in the right place at the right time. If you strictly look at Shinoda’s resume in 1956, you might ask, “How did this guy get in the front door?” As a young man, the only thing Larry ever graduated from was high school, Army boot camp, and the School of Hard Knocks. Twelve-year-old Larry had his life turned inside out when along with thousands of Japanese-Americans, he and his family were sent to interment camps for the duration of WW II. The experience had a profound effect on his personality. A self-professed “malcontent” Shinoda could be a little difficult to work with.
After his Army tour of duty in Korea, Shinoda attended Art Center School of Design in Los Angeles, but truly hated being there. He could see no purpose in taking the classes in design and the various art mediums, such as watercolor painting. He was a car guy/hot rodder and he wanted to draw and design cars! So he left Art Center without graduating and based strictly on his car illustrations, landed a job at Ford, then Studebaker/Packard. Just a year after starting his career, he landed a job as a designer at General Motors.
The rest is the stuff of legend. Street racing and blowing the doors off of Bill Mitchell’s souped up Buick and quickly being taken under Mitchell’s wing. Things like that happens, but rarely. There was obviously some chemistry between the two men, perhaps it was because both men could be brash and had strong opinions.
Shinoda got his first big break when Mitchell tapped the 28-year-old to translate the body design of the ‘57 Q-Corvette on to the mule chassis from Duntov’s aborted Corvette SS project. The finished car became Mitchell’s 1959 Stingray Racer, which formed the styling theme for the ‘63 Corvette. From there, Shinoda got one peach project after another. It’s worth noting that the design of the Stingray Racer is held in such high esteem that current Corvette chief designer, Tom Peters (C6 Corvette and late model Camaro designer) is on record stating that his ‘09 Corvette Stingray Concept (aka Transformers Corvette) was influenced by the ‘59 Stingray.
During his almost 13 years at GM, Larry designed numerous special Corvettes, Corvairs, and several race cars, as well as his usual duties working out the styling details of various production cars. Presented here are Larry Shinoda’s most important Corvette designs. Later this week, we’ll take a look at Larry’s very slick Corvairs, and race cars, including the body design for Pat Flaherty’s 1956 Indy 500-winning Watson-Offenhauser.– Scott
1959 Stingray Racer The 1959 Stingray Racer is still a stunningly beautiful car design. The idea of a “broad, flat top surface” was to create a reverse airfoil that would pull the car down. The problem was that the sharp leading edge was too high and at high speed, more air was knifing under the car rather than going over the car, causing a serious front lift problem. The production Sting Rays and even the Grand Sport Corvettes all had the same trouble. This could have been corrected with a slight forward rake, if the nose had drooped down a n inch or so, and a chin spoiled was added. The Grand Sport replica cars from Duntov Motors use these corrections and front end stays where it belongs at high speed – DOWN.
1963 Sting Ray Concept Art The road to fully worked out new car designs was littered with concept art – most of which was probably thrown away. Here we see a headlight treatment study. Sorting out the production car’s rotating hidden-headlight design was a brilliant but challenging project. Note the absence of hood lines and windshield wipers. It also looks like they were considering scoops on the back edge of the doors.
1961 Mako Shark I Showcar – AKA “The Corvette Shark”
With the basic Sting Ray design approved for production, Bill Mitchell had Shinoda design an exaggerated version for a teaser show car. Known today as the Mako Shark-I, the car’s original name was simply, “Corvette Shark.” 1961 was still the “Jet Age,” so the car was originally shown with a plexi bubble top. It was kind of “Jetsons” neat-looking, but would anyone really want one for their daily driver?
1963 4-Seater Sting Ray Split-Window Coupe
The XP-720 4-Seater Corvette Sting Ray was an exploration into the possibility of the Corvette competing with the much better-selling Ford Thunderbird. Ed Cole, head of the GM car and truck group, thought it was a pretty good idea. After all, GM is in the business of selling cars – LOTS of cars. Since the public bought 73,051 Thunderbirds in 1961, compared to 10, 939 Corvettes, it seemed like a no-brainer. The story goes that a tall executive got stuck in the back seat and needed quite a bit of help getting out. The 4-seater concept was quickly dropped. Good!
1963 Production Corvette Sting Ray Split-Window Coupe
Look at 1963 cars from America and Europe and there’s NOTHING like the Corvete Sting Ray. The split-window was one of Bill Mitchell’s pet design elements and was a one year deal. Although the design concept of a “split rear window” wasn’t new with the Sting Ray (the 1950 VW Beetle had a “split” rear window), the overall presentation of the Split-Window Coupe Sting Ray looked like NOTHING else.
1964 XP-819 Rear-Engine Corvette Engineering Study
The Corvair was the only production car to come out of Ed Cole’s ‘57 Q-Chevrolet initiative and was considered very exotic when it came out in 1960. But trouble quickly set in and it wasn’t just Ralph Nader’s doing. The early Corvairs were not good cars. But the “rear-engine” concept was very alluring to Chevy engineer Frank Winchell. Frank insisted that with the correct size tires the inherent oversteering problem could be corrected. Winchell envisioned a rear-engine Corvette and Zora Duntov said, “No!” To prove his point, Winchell had Shinoda design a pretty body to cover the big V8 engine hanging out behind the trans-axle. Upon seeing Shinoda’s rough full-size drawing, Duntov asked, “Where did you cheat?” Where he cheated was that there were no real rear bumpers or crash zone on the back end. The concept was quickly dropped. it was also discovered that the car did excellent wheelies!
1966 Running Mako Shark-II Showcar
Bill Mitchell verbalized the parameters of the design and Larry Shinoda and a small group of designers and stylists worked out the details. It was as if lightning had struck twice – first with the Sting Ray and a few years later with the Mako Shark-II. The exaggerated fender humps have become THE signature Corvette profile. A non-running full-size version was shown to GM’s management in ‘65 and received unanimous approval as the next Corvette. While the new body and interior designs were being worked out, a second “running” Mako Shark-II was built to keep the Corvette fans stoked. Almost 50 years later, the Mako Shark-II is still a jaw-dropper!
1991 Mears-Shinoda C4 Corvette Body Kit
Larry left GM in 1968, stayed at Ford for one year, then formed his own design studio where he worked on all kinds of automotive and non-automotive design projects. Corvette body kits and add-on parts became very popular though the ‘70s and ‘80s. Three-time Indy 500 winner, Rick Mears teamed up with Shinoda and businessman Jim Williams in 1991 to create and offer the Rick Mears Special Edition Corvette.
Arguably the cleanest full-body-kit ever offered for a C4 Corvete, the coupe version lowered the coefficient of drag on the car from .34 to .30. The complete kit cost approximately $5,200, plus $3,000 for installation, and around $1,000 for a new paint job. With a cost of just over 10 grand on top of a $32,455 new ‘91 Corvette, there weren’t many takers. But, it was a very nice design.
Shinoda C5 Sting Ray Concept
The all-new C5 1997 Corvette was released in the Fall of ‘96 and Larry Shinoda got right on it. Note the date on the rendering, “1-6-97.” Obviously, Larry wanted to see more “Sting Ray” in the new C5. If you’re a mid-year Corvette fan, Shinoda’s concept looks pretty good. Larry died the following November and to the best of my knowing, there was never an effort to make a full-body kit based on what may well have been Larry’s last Corvette design project. Any fiberglass fabricators out there that would like to take a shot at the Shinoda C5 Sting Ray???
Not only is there a ton of beautiful cars at Barrett-Jacksonauctions, there are also a lot of venders. Anything from car care products, to engine builders to custom building shops.
One of those was Karl Kustom Corvettes located in Des Moines, Ia. I had a chance to speak with Jim Hidy one of the reps for Karl Kustom at the auction this past January.
SWEET!!!!
Nice looking car, yes? HELL YES. But there some interesting things I didn’t know about these custom Vettes and how they are made.
I spoke with Jim at length and I have to tell you that how I thought these were made wasn’t even close and how they are made was pretty surprising to me. Jim set me straight.
Great Creation
These are of course C6 machines with the look of the 60’s Vettes. All the great handling and power of the C6 underpinning and classic looks. I thought ‘how cool they manufacture a body that snaps on the C6 frame. But that’s not how it’s done.
As the Washington D.C. auto show took place, President Obama decided to make a visit. Truly impressed with the American muscle & sports cars. Though he checked out many new models and the likes of the controversial most iconic American sports car, Chevy Corvette(photo above), it seemed like the new Ford MustangShelby GT500 Super Snake; or simply Shelby GT500; is what really grabbed his attention by stating, “This is sick”.
Since I’ve gotten the 4 speed ( T-10 from 1967 Shelby) in the Mustang, I’ve been driving it a lot more. I’m surprised at how much of an improvement it has made in the drive ability. Of course there is more power going to the ground which is remarkable and the RPMs are put to much better used. The original three speed top out pretty quickly and nothing left but engine noise.
Of course with more power hitting the ground, my current tires (wide and hard) tend to grip a lot less and spinning them through 2nd gear is common. That will required some new, softer tread before long.
After driving the Mustang a few days in a row, I took the Vette to work. Now you would expect there to be a difference, especially with the 120 hp disparagement in power the Vette (about 420) and the Stang (about 300 – maybe a bit less) , but what I notice is how both cars arrive at top speed.
Both car’s like to launch, but the Vette does so with much less rear hunching then the Mustang. The Vette feels lighter as it gets up to power – less down force on the road. The Mustang is much different. You can feel it, feeling the road. I can actually feel the power longer and deeper in the Mustang as it move on up through the RMPs and the gears.
I think I’m ready to at a tach to the Mustang, I need to see the RPMs it’s turning out and then I’m going to have it dyno’ed. It will be a good baseline before I get the 351 CJ head and intake installed.
One of my regular readers, Bill, posted the following question in response to the piece I wrote on Chevy engines. Bill asked…
“No 454 V8 in 1971? I guess that motor came later. ..”
That get me to thinking so I did a little more research. The references I’m use are “Ultimate AmericanV-8 Engine Data Book” by Peter Sessler; “Standard catalog of American Cars” by John Gunnel and “110 years of the American Auto” by James Flammang and Auto Editors of Consumer Guide. I try not to get too much from the Internet at large.
Interestingly enough the 454 is briefly mentioned in the Ultimate American V-8 Engine Data Book, but there aren’t many details. That reference shows that the 454 was available in 1971 as a 4V producing 365 horse power. It doesn’t show under any model just as a general option for Chevy’s. I’m assuming it was just a 400 block with a different bore and stroke.
The 454 was developed by 1970. It’s bore was 4.251 in and had a 4 inch stroke (where as the 400 had 4.251 in bore and a 3.75 stroke). There were other version in 1970 and 1971, designated as the LS5. This version of the 454 was used in the 1970 and beyond in Corvette for one instance and was used in Chevelle.
Interesting that it isn’t referred to in the mentioned references for 1971 year.
Hold the presses!!!!!
It appears that in the reference “Standard catalog of American Cars” by John Gunnel that the 454 was left out off the comprehensive listing of engines for 1971. However, the 454 was use in the SS version of the Monte Carlo – 1,919 were produced. For the Chevelle 80,000 were sold with the SS badge of those only 19,992 were with the 454.
1917 Chevelle SS 454
1971 Monte Carlo SS 454
And in this reference I found the answer to a question I’ve had for some time. About 5 years agoing I was at a car show and ended up talking to a guy with a 1971 Nova SS. It had a 454 as the power plant between the shock towers. However there were 7,015 Nova SS packages sold, none had the 454 as the option.
That extra boost comes from an intricate custom turbocharger system featuring a 118mm turbo, custom air to water intercooler, Tial wastegate and blow off valves, and a 5-inch downpipe all working to the tune of 34 PSI manifold pressure.
After completing the build in March, the Hinson Motorsports crew took Record Hunter to the Ohio Mile, an East Coast Timing Association event in Wilmington, Ohio on April 29th to see what it could do. As the first standing mile event the Corvette raced at since its build, the April Ohio Mile proved to be a great tuning opportunity for the crew since the mile race was speed-limited to 150 MPH.
