Raver Motorsports SLC Build Thread

I'm a fairly new member here so I would like to start by introducing myself. My name is Hill McCarty and I'm the owner of a performance shop outside Baltimore, MD. I was recently contracted by one of my customer to build a race variant of the SLC for their race team, Raver Motorsports.

We've started a build blog to document the build process. Here is the link to the blog:

Agile/Raver Superlite Coupe | The evolution of a track car build

I will be copying the text from the blog over to this thread as the build progresses. I'm not going to be linking to all of the pictures here as I would rather spend my time building the car than posting everything to 3 separate places. I'm sure you all understand.

Here is the first post on the blog. Some of you who've been on the boards will know a little about the start of our story.

Those of you that have been to the shop know that we’ve been hard at work on a big new project. For those of you that haven’t been in for a while, let me give you a quick introduction. At the end of last year Agile had the privilege of partnering with and supporting Team QRP with their Superlite Coupe (SLC) for a bid to win the NASA 25 Hours of Thunderhill. While we didn’t win the race due to a steering rack failure in the 18<SUP>th</SUP> hour of the race, we were 5 laps ahead of the nearest competitor and held the overall lead for well more than half of the 18 hours we ran. This was our introduction to a brilliantly put together kit car with enormous performance potential.

When we got back to the shop, we couldn’t help but sing the praises of the SLC and as a result one of our racing customers made to decision to take the plunge and have us construct an equally capable machine for his race team, Raver Motorsports. <?xml:namespace prefix = "o" ns = "urn:schemas-microsoft-com<img src=" /><o:p></o:p>
Once Raver Motorsports had determined that the SLC platform was going to be the new flagship in its garage, we set about making arrangements with Superlite Cars to get their race-prepped bare chassis, race spec suspension arms and uprights, fiberglass body and race spec aerodynamic package. Since we knew from the start that this was going to be a race-only build, we preferred to start with a clean slate rather than a rolling chassis. This way we have absolute certainty that every part we put on the car is just as we want it to be. Starting with a minimum of parts also allows us a lot of freedom in spec’ing the absolute best parts for us and the racing environment we intend the car to be used in. <o:p></o:p>
The car will be built as a dedicated track car, maximizing agility, reliability, and minimizing operating costs. As a result, we selected the Chevy LS3 engine for a power plant and the Graziano 6 speed transaxle from the Audi R8 for carrying the power to the rear wheels. We will be using standard calipers, rotors and pads (no carbon/carbon here) and will be pumping standard 93 octane pump fuel to keep cost down. Tires are just expensive no matter what for this car so there isn’t much we can do to minimize operating costs there.<o:p></o:p>
Let the fun begin!<o:p></o:p>
Congratulations on the SL-C project. Oh, welcome to the forum!
The LS-3/Graziano will make a great combination. The stock Brembo's
are a little heavy for a race car, but should do the job well.

After a few months of waiting anxiously for an SLC to put in the newly cleared build area in our showroom, it arrived late on a Saturday afternoon in late April. One of the team members had driven overnight to Detroit to pick up the parts of the car, load them in a trailer and bring them back to the shop. It was a bit of an interesting experience to have a car come into the shop in so many different pieces. We usually get them in one piece, and take them apart before putting them back together.

<FONT size=3>Initially the chassis and body sat covered from prying eyes until all of the team was able come up and see the bare car before work began. Once the team owners had seen the car and given us the go ahead, work began in earnest, albeit slow at first since we were largely still preoccupied with the Raver Motorsports STi. We spent a couple months picking away at small tasks until our race schedule allowed us larger blocks of time to focus our attention on the new build.<?xml:namespace prefix = "o" ns = "urn:schemas-microsoft-com

Agile/Raver Superlite Coupe | The evolution of a track car build
Hill, I welded up a dolly that fits precisely under the center chassis section. It's on casters on all four, and easily pushed around with the engine and gearbox in place.

I probably could have made it a bit higher though. My back talks to me after a couple of hours.

The LS3 is tried and true, and we have a lot of experience on it so the choice was a no brainer. We're looking forward to getting some time on the Graz. It seems to be very robust so our expectations are pretty high. We'll be using an AP brake components in a package of our own creation. I'll be posting more on that later in the build.

We also use an large, heavy duty cart we got from an old forge downtown for moving the chassis around the shop. It's a bit of a hassle to get the car down off the stands and onto the cart but it saves a lot of back pain so its totally worth the extra work.
Work Begins

Since we started off with just a bare chassis, it didn’t look much like a car to most of our customers. To start to get the project looking like a car we began by getting the necessary parts to get the suspension on the car. Slowly, rod ends and spherical bearings and safety washers trickled in and were assembled onto the uprights and A-arms. Then the rear arms and uprights were bolted to the chassis.

We’re still waiting on a few parts from Superlite to complete the assembly of the front suspension, though that should be done shortly.

At the same time, work inside the fuel cell was being done to assure a constant supply of fuel to the lift pump that fills the fuel swirl pot(surge tank). This is a bit of a dilemma with the 28 gallon cell we’re running since cornering causes the fuel to slosh from one side to the other of its 4+ foot length. The foam in the cell helps but won’t be enough to keep constant flow to the pick-ups and lift pump. I would like to thank Ted and Don at QRP for their input on a tried and true in-cell setup that does not require in-cell pumps.

The SLC’s fuel cell is directly in front of the engine contained within the space frame and the only access point is blocked by the engine. Due to this inaccessible location, we wanted to have as little as possible to fail inside the fuel cell or the fuel cell covers. This is why keeping pumps out of the cell was a worthy goal since a pump failure in the cell would mean certain retirement from any race.

When we reinstalled the cell in its enclosure we also found that it was slightly smaller than the enclosure itself. To keep the fuel cell immobilized and prevent it from sliding around, chafing the bladder, or stressing the connections we padded the inside of the enclosure with 1″ thick sheets of high density foam. A little bit at the front and sides of the enclosure fully immobilized the bladder and was enough to leave us feeling comfortable that it was going to stay put.

Well it is about time you started posting about this build.

Like reading your posts.

BTW... the link to the blog does not work. Link should not have www.gt40 in it.
It has been a while since this thread has been updated. Well, here it is!! The car is proven so far. We have a full season on it with several first place finishes, a 2nd place national championship title, a top 10 finish in an ultimate track car shootout and a top 5 finish in a 13hr endurance race! Most updates will be found on our facebook page but I will try to give this thread the attention it deserves.





Thanks for the photos. let us know if you post any more youtubes. that "Chasing daytona prototypes" was great!
