I would "Like" it if I had a facebook a/c.

I don't do any of the new-fangled tweeting type things. Who wants to know how many times I brushed my teeth this morning or what I get up to when I'm drunk.

That is an Aquila CR1 - nothing at all to do with an Ultima. It is a purpose built, (very) high specification racing car from Denmark. http://aquilaracingcars.com/ Its significantly bigger than the Ultima, and lighter (with a price tag to match the specification!). I will try to dig out a photo of the two cars side by side for comparison.

It has caused quite a lot of controversy - some deemed that its not quite in the spirit of GT racing - its far closer to an LMP prototype than a production model.

Does have some resemblance with a space craft, or rendering of one. Could also be considered an egg with 4 wheels

As long as they sell a road car version then it would be a true GT car, if there only race track cars then they have a point it would be closer to a LMP only car....

The thing is most of us want the old saying (Race car for the road), so a LMP road car is kind of what made the GT40 and 962 road cars famous, as we could see ourselves driving them to the Pub...... well I could anyway.... So GT / LMP is kind of grey area, how may road cars make a LMP a GT Car ?? used to be 25 for the ACO (917 days) and about 200 for the WRC (Group B days) no idea what they class as a GT production car now but the Ultima GTR has to be close to enough road cars now to qualify for some thing ???

It used to be that 25 examples had to be manufactured, so clearly the Ultima is fine in that respect. Not entirely sure what the rules are regarding homologation though.

Hi guys,

Just wanted to provide a further update with progress on the pre-season development. Over the last couple of weeks there has been a huge amount of work done on the car, which is as follows:

- The wiring loom has been rebuilt with some redundant parts removed, and it has been re laid out in the engine bay to protect it from debris. The telemetry loom has also been started which will incorporate the old telemetry system as well as some new sensors including LP and HP fuel pressures, fuel temperatures from engine return and swirl pot, ambient (under clam) temperature, brake and clutch pressures and four wheel speed sensors.

- The fuel system now has two HP and LP pumps in parallel to give redundancy should a pump fail. A larger swirl pot has been fitted which is positioned in the RH side pod by the cooling air.

- All wiring and hoses were removed from the engine bay, the chassis was resprayed and some extra heat shielding was added.

- Full flat floor has been complete. The splitter is now attached to the chassis and is supported by a frame attached to the front structure of the car. Brake ducting is all attached to the chassis, so the front clam can be removed quickly with only the lights to be unplugged - this plug has been relocated on the front bulkhead. This all lowers the car by 40mm which will improve our suspension geometry and gives us a huge aero improvement.

- Engine reinstalled.

Further work still to be done, and we are working hard over the coming weeks to get the car ready for the start of the season. Further upgrades include:

- Front brake upgrade
- Damper upgrade
- Installation of air jacks
- Slight suspension and chassis tweaks
- Further modifications to the cockpit for driver comfort and individual control of fuel pumps etc.
- New exhaust system to cope with tighter noise regulations due to Silverstone being thoroughly unreasonable!
- Further aero/cooling modifications

We are also looking at a gearbox upgrade to a full race specification sequential dog box, however this is pending the sale of our old (freshly rebuilt) G96/50.

There is also a lot of work going on 'behind the scenes' with sponsors and suppliers, and we plan to go live with our online shop in the next few weeks, along with some website updates. We have also welcomed two new personnel to the Team this year, which will be a huge benefit to us. We were hoping to get some decent shots of the various parts of the development this weekend however time got the better of us - we will include some in our next update!

You have been very busy. I know how long some of these things take. When modifying you change one item and it often impacts on other parts so you have to fix that as well.

I look forward to the pictures.

A few more updates for you...

This last weekend was spent finishing off the loom, which is now complete barring a few sensors and the connections for the new gearbox which should be ready for round 2, but that is a story that will wait for another day!

The new brakes arrived, which are rather tasty - 378mm x 36mm discs fitted with 6 pot endurance specification callipers fitted with 25mm thick pads, all with super light custom bells and mountings designed specifically for the Ultima GTR hubs (available from your local MacG Racing branch soon!). These should provide some serious stopping power and should (hopefully) get through a 24hr race without a pad change.



They are rather big, this may do the size more justice!



The engine was cleaned up and plumbed into the nice tidy, cleaned and reconditioned engine bay which has extra heat shielding fitted round the tank and a replumbed fuel system. The sidepods were refitted, along with coarser, more robust side mesh (to let more air through) and the beautiful carbon side scoops fitted. You can just see the fuel system peeking through the grill mesh if you look carefully.



The front chassis bracing was all made up, which is currently being welded to the chassis as I type, and the airjack fitting brackets were also cut out and welded to the chassis. (you can see one of these clamped up in the picture with the brake disc on the car).



The flat floor and splitters which are attached to the chassis were completed, and are awaiting fitting, which will be done once the welding is all completed. We are currently awaiting dampers which have been custom designed and made specifically for the Ultima GTR (again available from your local branch of MacG Racing!) then we only have a few more jobs left to do (including the redesign and manufacture of the new exhaust system) then we can complete a shakedown run then hit the testing seriously before the start of the season. It will then be tidied up ready for a photo shoot and the first round at Silverstone on March 24th. The car should be a different animal and hopefully we have addressed all the little gremlins that got the better of us last year. Speaking of which, here is why we lost drive in the 24hr back on October - £900 pounds worth of 3rd gear on the right and in the middle, with the remains of 4th on the left hand side...



Enjoy!

Jonny

I almost bought an aquila Cr1 a while ago, for some strange reason all the original buyers I spoke to who ran the cars in the original race series had nothing good to say about them with a few reports of the cars actually falling apart as they drove them. Although the one running in britcar has had some success it is a much updated and much modified car running an ls7 rather than the original bmw motor... I would still like one, but not at the silly prices that were quoted to me by some people who bought them cheap from the original owners and seemed to be valuing their cars at almost original factory prices with hidden faults (which can be found out about if you do your homework on any previously race campaigned car)

like that rear wing..

does it create too much down force at the back??? and now you need additional front downforce?

http://www.pistonheads.co.uk/sales/3375587.htm for sale here!

Actually I'm interested in these or more to the point are they any good. I have been told that they actually Hamper air flow rather than aid it!.
Any thoughts

Russel will make you some of these. he makes them in GRP and can make them in carbon too.

Im sure he will be about soon

A very generous forum member donated them to us - and yes they are indeed full carbon. We don't do carbon wrap! I think they would probably hamper airflow at lower speeds but the under clam temperatures have reduced considerably at high speed.

The rear wing does give a lot of downforce, this year we have fitted the splitter to the chassis and enlarged it another 10mm. We have also got a flat floor from the front of the car all the way through to the engine bay and it has certainly made a difference to the front end grip at speed. You can see the splitter here prior to the brake ducting being fitted:



This was tested yesterday at our first shakedown test, which was completed at Blyton Park in the afternoon. The test went well, with the modifications all coping with the stresses we placed on them. The instrumentation showed that the redesigned and replumbed fuel system peaked at just over 30 deg C (after 30 minutes of continuous running)and the swirl pot was at ambient.

The larger brakes were superb, as were the new dampers. We have stiffened the chassis considerably at the front, and this combined with the dampers, has helped directional changes considerably. Unfortunately progress was halted by a broken gear shift cable, however this is an easy fix. We must apologise for the lack of pictures recently, things have been a bit busy of late. The 'launch' day is on Saturday at Oulton Park, so there will be more pictures coming along shortly!
