UVD Puma sports libre project

Hi All,
I thought I would share with you our Project Puma car

So far it's been a 5 year project with a number of ups & downs so I'll try to be brief & concise so as not to be too boring with details :

The car was initially conceived with a US partner as a cost effective rallycross vehicle which we've converted to be compliant with UK hillclimb/sprint regs, we've raced a couple of times at Curborough so far this year in sports libre



It's a mixture of bespoke & OEM components to contain costs, make it pretty straightforward to produce & cheap to service/repair, weight is the penalty for this, however once we have a bit more experience & we're happy with reliability we can start working on this



Currently we have the one up & running car which we're using to establish the spec not only for the setup but also the modifications for UK ROPS/vehicle passport eligibility & then we have a further 2 chassis sets parts which we can modify/assemble hopefully for next season

The engine bay will accept most motorcycle engines as well as well as FWD engine/gearbox assemblies, we've already done a test fit with a Hayabusa & fitted a Honda K20A engine/gearbox assembly in CAD

General vehicle spec :

Wheelbase : 2050mm
Track width : 1600
Engine : Standard 2011 Suzuki GSXR1000
Drivetrain : Bespoke gear drive, ATB diff unit
Overall weight : 420 kg wet
Front suspension : Double wishbone
Rear suspension : Semi trailing arm
Tyres : 190/570 R15 Avon slicks

If anybody is interested in anything further please let me know & I'll post details on here

Cheers

Colin

Why is it Sports Libre. Looks like an open wheeler racing car or can you choose?

Not completely sure why its in Sports Libre, we were trying to get into the 1000cc racing car class but we were told it wasn't eligible so they've put us in "Sports Libre/Racing"

On what grounds were you rejected and by whom? (MSA or event)

I could see that you could possibly have bodywork which is too wide for a racing car (single seater) per (S) 15.1.1 - Maximum width behind front wheels 140cm.

Only other thing could be if your main roll bar and stays do not comply with (K) 1.6.3

It can't be sports libre as the wheels are not covered.

Roll hoop complies with 1.6.2 but I don't see why it wouldn't conform to 1.6.3 :



Wheels don't need to be covered for Sports libre/racing class

Bu****d if I understand the rules then !
So if you make a car that doesn't comply somehow as a racing car it gets put into sports libre. That is a little unfair on the sports libre category !
The car looks like it is a grass track car not a sprint car.

Certainly looks like the bar/braces should be compliant with 1.6.3 as well as 1.6.2.

How wide is the bodywork just in front of the rear wheels? (needs to be less than 140cm).

Why should the perception of how a car looks effect which category it runs in?

Brings to mind the sports libre 'mini' shaped car (no Mini parts) which was deemed to be a commercial vehicle as it had a passing resemblance to a Mini pick-up.
