Searching: Some good pictures of a Jaguar XJR-12 IMSA

Post by racingkars »

For a possible conversion project i need to find pictures of a Jaguar XJR-12 IMSA.
Tough to find on the web.
Does anyone have pictures or know of a good source?

Thank you for your help!

Are you looking for anything specific? I have a ton of pictures I used to work on these cars.

Here is 5 pages of XJR-9 and XJR-12 images. In fact pages 2 thru 5 are of the car we prepared here in the US that was sent to LeMans in 1990 and won. BTW virtually no difference between the IMSA XJR-12 and the Group C XJR-12. The only real visual difference would be the underwing tunnels and well it is the bottom of the car so not really visible.

Unfortunately they are on my old Photobucket account which really isn't user friendly any longer.

Let me know if I can help

Hi Kars. Now that Icon says there is not much difference from the Group C version, the Haynes Group C XJR manual is a good source of info and details. If you dont have access to a copy of the book let me know specific details you need and I will scan any appropriate pics for you.
Cheers. Tim

Well, I have 2 Studio27 kits of a XJR-12.
One is the 1990 Le Mans kit and one is the 1991 Le Mans kit.
I would like to see if i can convert the 1991 kit into an Imsa version (Lammers 1990).
Only pictures of the bodywork are needed, there are no engines in the kit.
I need to see if the conversion is doable and what needs to be changed.

All pictures are welcome.
Thank you for your link, Derek. Much appreciated.
Thank you too for scanning some pictures for me, fastbackfreddie.

Thank you for your help.

I'll be out for a few days as of Saturday.

Kars, hopefully some of this maybe of some help to you.

These are from the Haynes book. I left the text for more info.

This one came straight of the web

Its interesting that in this article Jaguar still refer to it as a XJR-9.

A few more pics that might be useful.

Just looking at the studio 27 bodies you have, an obvious difference is the big splitter missing from the front nose.

Icon probably has far more info to add...

Superb! Thnx Tim!

Looks to me these are the points of interest.
Not sure about the hump on the back, but it looks like it's bigger, more to the top of the roof.
Maybe Derek can confirm this.

Google is a mess when searching for this car... half the time the XJR-9 pops up.

Yes, I think you are correct Kars. The hump is too low - it should be more in line with the roof.

Let us disregard the Bud Light car - I give you a bump steer :lol:

It is a mess searching for this on the web!
We do know it is chassis 388. The confusion starts because it began life as XJR9, then was modified taking on model XJR-12D, but chassis remained as 388. This is why so many photos pop up showing XJR9.

This shows the timeline of chassis 388 (we will assume the data is correct, it almost corresponds with Haynes data :wink: )

Anyway, hope the hump issue hasn't killed off your project idea.

Hi guys,

Sorry about the missing images. Photobucket is a PITA even though I'm paying for it!!! Click on the missing image marker and it will take you to the image...

TWR was never in the habit of designating chassis with "A", "B", or "C" they generally just gave it a new XJR-#. TWR started their chassis number to follow what Bob Tullius had started with on his IMSA GTP Prototypes. Tullius created the XJR-5. TWR's first prototype was the XJR-6 and the chassis stayed virtually unchanged thru to the XJR-12D even though there were 5 very distinct cars that raced as TWR V-12 Prototypes from 1985 to 1993 in the XJR-6, (XJR-7 was a Tullius car) XJR-8 (Tullius also developed an XJR-8 which Group 44 called the Magnum but it never raced. It was more or less a rebodied XJR-7), XJR-9 and XJR-12. Each new chassis designation was a development of the previous chassis. I'm not 100% sure but I think that XJR-12 and XJR-12D means the same thing. The "D" stands for "Daytona" Tony Dowe is who ran TWR/USA and he like to stand out from the others at TWR so he would come up with little things like the "D" so as to set the US squad apart from the rest at TWR. The XJR-12 designation first appeared at Daytona in 1990. In 1992 and 93 it was advanced to XJR-12D though no significant updates (other than the livery) had been applied to the cars since Daytona 1990. Honestly, Tony may have wanted to change the chassis designation simply for the new sponsor that came on board in 1991 in Bud Light. Though the 12D was seen at Daytona on the backs of the cars in 1992 & 93 the last V-12 car built could have easily been redesignated as it had significant body and aero mods made but it was still called an XJR-12D at it's only race at Daytona 1993

The NACA ducts in the nose next to the head lights are the brake scoops. They replace the openings that are below the headlights on the XJR-9 Those are a trate belonging to the XJR-12.

The oval opening in the center of the nose between the brake NACA scoops is driver fresh air and that is a trate leading all the way back to the XJR-6.

The bump on the engine cover is the remnants of the engine air intake from the XJR-8 and XJR-9. Hard to tell but the picture posted above of the two Castrol studio shots looks like it has the old engine cover though it may simply be that it is and old engine cover that was modified here in the USA and not a engine cover from the composite shop in the UK. While we had the ability here in the USA to do anything we needed to do with regard to the composite structures we did not have the molds so there is a good chance what differences you are seeing are because we made mods on the fly and not in the original molds. The Bud Light car above clearly has a bump lower then the roof line but that could be because the mold was changed and that is how they did it in the UK. You will have to make that decision as to what you feel best represents the 1990 car you are creating. The bump is still there because the engine airbox will not fit without it. So when they did away with the air intake on the roof they couldn't completely remove the bump.

The NACA ducts on the side of the engine cover are for engine air intake. Those are also a trate belonging to the XJR-12.

The large NACA ducts below and in front of the Engine intake NACA ducts should be filled and replaced. We ran the a similar configuration to what is depicted on the Tamiya XJR-9 Lemans car. Which has two vertical slot scoops on the left side of the car feeding the engine oil radiator. This is where it get tricky. The right side of the car had one vertical slot scoop which feed the transmission oil radiator (which is different than the Tamiya kit) along with a small NACA duct (which is in the Tamiya kit) that feed fresh air for either the starter or the alternator don't remember which. You can find good pictures of these features in the Photobucket link I sent you. In the pictures of the car being built up for Lemans 1990 was installed the same arrangement we used at Daytona. The configuration was changed once the car arrived at TWR UK before the race at Lemans.

Here is what it should look like.

Left Side:

Right Side:

Image



The NACA opening on the rear wheel cover is curiously missing from the Studio 27 kit. That should be added. That feature goes all the way back to the XJR-6. That opening is to aid in extracting hot air out from the wheel well.

A couple of things you will need to consider adding.

Additional air intakes in the nose of the chassis (see red arrows)

Image

Louver on the engine cover (see red arrows)

Image

I think that answers all of the questions if you have any more let me know.

BTW Jan was one of the best drivers I ever had the chance to work with. He was humble and a pleasure to be around unlike Price Cobb who thought everyone was beneath him.

Here are the only images I have from Daytona 1990.

Thank you Derek for this valuable information. Much appreciated!
I am going on a short holiday for a week now.
After i am back i will study the project with interest.

It looks to me like it might be doable....
I have the XJR-9 Castrol decal set.
I need to see if it fits a bit....
