Car #1 just arrived back from the US after Monterrey etc and I drove it for the first time at the weekend. I am not easily pleased but I was reduced to a grinning, screaming idiot the first time Richard opened the taps and the car shot off up some fast but tightening uphill bends. The engine is incredible. Pulls like a train from 3500 and the cabin is flooded with hard edged metallic induction sound that makes the hairs on the back of your neck stand up if you have even a drop of petrol in your veins. With current gearing (under finalisation), you spend most time in 3rd and 4th for country hoon B road speeds (within the 40-80 bracket). I was “limited” to 8000 as the car has done its first 1000 miles in the US including 50 laps of Laguna Seca (I have some cool video of Richard perfectly calmly crossed up down the corkscrew). So they will strip the engine and also finalise mapping.

It is not just the engine though. The super light weight of the car and the passive suspension have resulted in a car that preserves the feel of an old air cooled 911 but updated it. Traction is immense. But the way you can keep the gas pinned over broken, rutted surfaces and adverse camber is astonishing. The brakes (Tuthill’s own calipers and carbon ceramic rotors) are very effective, progressive and full of feel.

My car has been moved up from build #3 to #2, the carbon panels are going on now and we are finalising the interior design with Callum Design. I started this journey 3-4 years ago with Richard, with a project to create a light weight RSR kind of car for weekend A/B road hoons and Alps road trips. This got folded into the 911K project and I am glad it did because this car has already put itself next to my Carrera GT as my favourite driving tool. I am still fizzing. Will share lots more details in due course if you are interested.

This sounds like it should be an amazing story ... have you decided on the aesthetics ?

So many decisions ! (Don't ask on PH you'll get 1000 opinions smile )

I've just been to Tuthill to look again at the spec .... 850 kilos which is 200k removed from the last of the long-bonnet cars on which it is based.

Magic ...

The spec of this car looks like it is about to raise the bar on Singer .... a Porsche Tuthill ....

If it was £250k I would far rather have this than a 992 Porsche Classic, unfortunately it will be a lot more, but still want ... need ?

Sounds great, I look forward to hearing more as it develops.

I would love to see some pictures whilst it’s in build if that’s possible.

Its a beautiful car but I wondered who developed the engine? You don just magic up a 4 valve 11k rpm engine air cooled engine? It took Singer years/millions??

Just wondering if they've borrowed the heads off a BMW1200GS (100mm bore) and done a few clever housings, bespoke cams, enlarged oil cooler etc?

Swindon Race Engines developed and built the 2.4 litre twin cam engines used in Opel Manta 400 rally cars campaigned by Jimmy McRae and Russell Brooke’s (amongst others) in the 80’s.
They know their onions.
