An important aspect of development of the C1 GTI Turbo was to ensure it performs well on a circuit as well as the road. Circuit racing was not really an option due to the costs of preparing the car, and the fact that it would then bear little resemblance to a road car.

Sprinting and Hillclimbing is an excellent way to hone a car by pitting it against competition against the clock. If you have never tried Sprints or Hillclimbs but would like to compete rather than just drive on a trackday it's a great day out !

For 2011 we decided to enter a few rounds of the All Circuit Sprint Championship to develop the car with a view to entering all the rounds in 2012. This series is run by Tunbridge Wells Motorclub now in its 100th Centenary Year.

The 2011 dates are as follows:

Sun 20th March Mallory Park

Sat 9th April Lydden

Sat 30th April Goodwood

Sun 29th May Snetterton

Sat 4th June Lydden

Sat 18th June Mallory Park

Sat 22nd Oct Lydden

For the first few sprints we are competing in the car with base boost only (96HP) in order to establish reliability.

Sprint Report – Mallory Park 20th March 2011

Mallory Park Sprint Track Map

This was my first trip to Mallory Park and I can confirm the reputation for friendliness was bolstered by a fantastic day out with all the camaraderie you expect at a Sprint.

The circuit had been newly resurfaced and we were to use all the chicanes. Starting from the start finish straight we head around Gerards then through the chicane of Charlies and Stapletons. Then along the Stebbe straight up to Edwinas chicane through here then uphill via the John Cooper Esses then into Shaws Hairpin. This very slow hairpin then leads us into the Bus Stop Chicane then downhill through the Devils Elbow.

This layout is effectively the Superbike circuit. This was the first time a Sprint had been held with this configuration. The aim with the car today was to ensure we finished and managed to keep the car in one piece for the journey home. Surprisingly though the car aquitted itself well for a first outing on an unknown circuit as the data below shows.

The Power to weight figures and weights are estimated or based on declared figures! (in this sport it's rare someone will want to say they have more power rather less!) For the purposes of easy comparison of times and to save time and space we are only including Road Going & Modified Production Cars excluding the Single Seaters and Sports Libre classes. After all no matter how well you build a tintop it's not going to beat a single seater.

As you can see from the times the C1 fared reasonably well and if you were to allow the 107% rule like they do in Formula 1 this would put the car on level pegging with an Elise R with a power to weight ratio more than double that of the C1. It just shows how depressing it must be for an F1 team to fail to qualify, at least i'd have an excuse for being beaten by a much faster car. Technically the F1 teams should have pretty much the same kit! 


Sprint Report - Lydden Hill - 9th April 2011

For the second time ever the C1 sprinted at Lydden. It made its first appearance in completely standard trim back in 2010.

On arrival it was easy to see which would be the quickest Mini before it had even got round the circuit. Immaculately prepared and being double driven by very experienced father and son crew (both racing drivers) and also sporting the more sticky 1b tyres which strangely have been allowed for 1 year in road going class.

Although the boost controller had been installed I chose to run base boost only on the day which equates to just 96 HP. In terms of power to weight ratio I was giving away 70% and nearly 70HP per ton to the rest of the class.

The C1 was notably quicker on the day than two modified production cars (with roll cages and sticky tyres) one an XR2 and the other an MX5. Unsurpisingly the C1 was slower than the banzai Minis which are nearly always quicker than all the 2 litres class cars. The best time the C1 posted was a 97.83 seconds 1.75 lap - not a bad time. This was as fast as many of the times achieved at Lydden by the same driver in the standard production 205 1.9GTI which sprinted before. So with just 96hp the C1 GTI is about as quick as the 128HP 205. With more seat time late 96 would be possible and with 110hp from the ECO-R controller possibly late 95's.
The best road tyred mini ran 90.27 and 1b tyred Mini 89.32. Bear in mind though the best 2000cc car only managed 94 seconds. In order to close the gap to the Minis power to weight ratio the C1 will need approximately 150hp or 155hp if I stay 15kg overweight. Oh dear. Nobody ever said it would be easy to compete against the king of the under 1400cc class. Still looking on the brightside almost within the F1 107% rule..

If budgets permit we will compete in 2012 and gradually work up to this level of power.
