I'm in Kent...

Not too far away then.

They don't only do tuning, they undertake any work on a Mini, mechanical that is.

They've done my suspension, brakes, rear diffusers, altered the battery tray, altered a Gen 2 exhaust to fit and engine works.

They have a dyno there so can also map.

Any details of the work done on yours plus pics?
Interested to learn the various elements. The diffusers for example...

Spec : -

KW ClubSports and adjustable top mounts,
Adj RCAs,
Uprated rear arb,
Mini Cooper front arb,
Whiteline adj drop links,
Polybushed where needed,
GTT upper strut brace, OMP lower strut brace,
Camber of – 2 deg front and – 1.5 deg rear
BBS RC wheels, 17 x 7 in chilli red with Yoko AD08 tyres.
IRO of 25 - 30mm lower than standard. GP is 10mm lower than a S or JCW to start with.

Engine / exhaust : -

17% SC pulley
Vibratechnic top mount
Polybushed lower mount
Cat Cam, 550cc injectors and remap…currently at 250 BHP, 210 WHP
Janspeed manifold & sport cat, Milltek centre pipe with R56 Scorpion back box.

Brakes : -

AP Racing BBK to front with 2 piece discs, standard discs to rear. Mintex 1144 pads and uprated fluid and Goodridge hoses.

Interior : -

Recaro Pole Positions in half leather, half alcantara (faux but still nice)
Dash, down tubes, armrests, gaitors and dash top done in black nappa leather with red stitching.
All interior plastic in satin black
JCW leather / alcantara steering wheel

Misc : -

Vented A panels..
Wheel stud conversion.
Black roof
Front vents in body colour.
Mini Challenge rear diffusers.

Diffusers need a silly amount of work to fit but look the nuts. Remove or shorten battery box, fit Gen 2 exhaust, cut rear valance. I had the battery box shortened and a smaller race battery fitted.




ClubSports



Different A panels



Interior work




AP Racing brakes with Mintex 1144 pads



Ending with a feature in ModernMINI




Currently sat at 250bhp on a safe map.
Had planned fitting a BVH to take it to 275 - 280 bhp but no point when buying a csl.

Goes like a stabbed rat as it is

Very nice

[Stumpy]

Like that a lot. Thanks for sharing...
I take it you've removed the rear seats?

GPs didn't come with rear seats. Just 2 armchair Recaros in the front.

With this being as highly modified as it is, very little will be done to a csl. Possibly the brakes and Supersprint back box.

Sorry, missed the fact it was/is a GP.

1320 are only a 2hr drive, so who knows...

Can I ask a few queries please?

Adj RCAs Say what now?
Uprated rear arb - which one?
Mini Cooper front arb - is this smaller than the GP? The GP induces too much oversteer? With the uprated rear have to not messed with the F-R balance?
BBS RC wheels, 17 x 7 in chilli red with Yoko AD08 tyres - I have 18" wheels which might be a bit too much - the ride is quite crashy. Do 17s, make for quicker steering?
IRO of 25 - 30mm lower than standard. GP is 10mm lower than a S or JCW to start with. So you're 25-30mm lower than a S/JCW or 25-30mm lower than a GP?

17% SC pulley - The GP/JCW has a 11% pulley I think? So this swap alone will free up 10-20bhp?
Cat Cam, 550cc injectors and remap - Who's map?
Janspeed manifold & sport cat, Milltek centre pipe with R56 Scorpion back box. I assume this is alot more fruity sounding than the stock zorst? The JCW is actually quite quiet.

Recaro Pole Positions - if the OEM Speedsters allow a rear child seat I'd be tempted.

Vented A panels..- where's this from? Like the look.

fit Gen 2 exhaust - what's the difference with the stock one?

Currently sat at 250bhp on a safe map.
Had planned fitting a BVH to take it to 275 - 280 bhp

What's a BVH ?

Apologies for the (Mini) newbie questions, but all very interesting and relevant!

No worries..
RCAs are rear control arms. Give the ability to alter rear camber.

Rear arb is Eibach. Helps to cure understeer

Front arb on a GP is a standard Cooper S / JCW one. Cooper arb is smaller dia and also helps cut understeer.

Changing those on their own may interfere with f & r balance but on mine the whole suspension has been changed and everything set up accordingly.

Going to 17 wheels would make them lighter, obv dependant on make, and will reduce the crashy feeling. Keep in mind though the std suspension is dire! not sure on the improvement of steering feel although run flats aren't going to help if you have them..

25-30mm lower than std GP so 35-40mm down from a S or JCW

Yes, the JCW inc GP has 11% pulley,as a rule of thumb going 6% bigger will give 6% gain on bhp. However, if you go above 15% you're going to need a bigger intercooler, the GP one has an additional 2 rows so can cope with the extra heat from a 17%.

The map is a Bytronic map installed by 1320. Need doing as with the cam the car wouldn't even start so the map is part of the cam package along with the injectors.

I originally fitted a Milltek and was happy with the sound but with having the diffusers it was in the way. Poke your head under the back end and you'll see the exhaust splits into 2, there are 2 silencers and it then joins back up to give the twin tail pipes. A Gen 2 exhaust is a straight through giving room for the diffusers. The current set up is quite loud but not obtrusive, when bumbling about it grumbles but doesn't scare kids....open it up and it howls

The A panels are from Orranje although the guy that owns it is seriously ill at the moment so nothing is happening.

BVH is Big Valve Head.

Ask whatever you wish bud, more than happy to answer,

A very short clip of trying back boxes, this is the R56 Scorpion..tried a Mini Challenge but was actually painful on the ears!!

Much appreciated pops.

Might drop you a PM, rather than clutter this thread up too much, with a suggested first visit to 1320 'splurge' !
