Can not wait to see the finish article. Be interesting to hear comparison between this and the Tuthill RSR wink
I never completed the RSR. Many of the ideas for that car (esp lightweighting) got rolled into the 911K (as well as tons of stuff that wasn’t from my RSR). Covid happened, and Richard came up with the idea of the high revving engine and a car to put it in and that’s how it happened.

Andrew, have you been to Tuthill for your latest test drive?
Yes! Went yesterday. Richard took me out in the gold car. It is now almost finalised. Dampers, brakes, gearing is done. Some final work on low speed mapping, plus exhaust system from headers onwards needs to become a little quieter without losing the top end howl (the system is on the dyno, incidentally so is my car’s engine!).

I have to remember the last time I was in the car was September, when I was blown away but we were also limited to 8,000 rpm. Yesterday there were no limits, and RT could and did wind it all the way to 11,000 many, many times smile

It is a VERY special thing. The engine pulls like a train from as little as 3,000 in 4th gear. I can imagine wet roads and 4th will easily see wheelspin. You can imagine the noise, the hairs on the back of your neck and your arms are all standing up and you are reduced to a gurning gibbering idiot as the rev counter arcs round to 11k pretty damn fast it has to be said (and no, not due to wheel spin). Gear ratios mean you hit c 90mph in 3rd and 140mph in 4th. Theoretically on a private road or track of course. It felt like it too, with plenty more to come but 5th and especially 6th are more for relaxed cruising. RT wanted the gearing so that, on the right road or race track, you use all the revs quite regularly. Though I can imagine most of the time if hooning you are doing 5-8/9k.

A lot of work has gone into the damping. They are 4 way adjustable passive units developed with Motion Control. But MC had nothing off the shelf so Richard spent a lot of time working with them directly. This is a very special suspension - firm yet compliant at low and high speeds, and we tried some bloody awful farm tracks. The car finds traction and grip and you are not slowing down or wincing or hearing the car crashing down on bumps. It would make mincemeat of a modern performance car on poor B roads.

The car just feels right now. Tight, OEM kind of quality if I can describe it like that. Tuthill are continuing to develop bits for it that they don’t really need to. Like the carbon handbrake lever. I thought it was a heater control next to the lever but it is the lever to engage reverse gear. Also they have some new machined window winders with carbon insert. They are also prototyping some “bullet style” wing mirrors; I don’t normally like these as they often look like a large lump of metal on a lightweight car - however they are being done in CF so let’s see. I can always have the normal flag style mirrors.

We had a conversation about when I can expect to take delivery. All the parts and trim materials are on hand. It is just going to take a few more weeks. Realistically July not June. It is bloody agony now, having been out in the gold car yesterday.

A typo perhaps? That's a long jump!

It's wonderful to hear the latest feedback. thumbup
It’s a lot of revs but I take your point, my memory may not be 100% on that smile

Do you know why they've gone for motion control for that (your)car?

Tuthill have been a long timer user of exe-tc.
I think Exe-TC dampers are being used on the series of IROC restomod cars they’re building.
Yes I think Richard set out with a particular set of aims for the car and felt MC was the way to achieve it. Many of the bits for the K are custom and new. Though it is comforting to know things like the loom are based on the tried and tested motorsport version.

Thanks both. I'm curious to know why now laugh What special sauce MC dampers have over exes.
As Slippy said, give them a call and ask.

All I can say is, I am very happy with the suspension.

Andrew, thoroughly enjoyed a good look around your car in build yesterday, looks absolutely stunning

Your colour choice is spot on! Can you say what colour you've gone for on the interior

Since seeing George Harrison's McLaren F1 after being painted which was colour matched to an aubergine, for me there is no more beautiful colour than a deep, dark metallic purple
Thanks! smile

Interior is mainly dark (but not too dark) rich brown with lighter creamy fawn for things like seat inserts and door cards, with various textures and contrast stitching. Dash panel is drilled metal painted same colour as exterior. Tobacco gold instrument bezels. Various bits of exposed carbon, but not too much. Carrera GT floor mounted pedals and wooden gearknob. That kind of thing.

The car is coming together with Tuthill continuing to develop some of the trim and design details which is nice to see, eg a Titanium key, new carbon door mirrors as an option instead of the flag ones, and so on. I’m told it remains on track for July.

Very quiet on here - how’s the car coming on ? smile
Shouldn’t be much longer ……………..

Expecting a timeline to complete shortly. I believe the carpet and headliner and glass has now gone in and the engine is in build.

Chris Harris wrote a short piece in the last edition of Top Gear and he has a video out “asap”.

Search @redshift75 on Instagram. You'll find an image of the gold 911K and a Singer DLS. The fourth image in that "collection" is actually a video shot from inside the car. It still makes me giggle every time I watch/listen to it hehe

And this has been posted since ... : https://www.instagram.com/reel/CwOuwz2AXd3/?utm_so...
Thanks I hadn’t seen that.

Quite excited!!

That gearshift action looks amazing.
It is a 915 gearbox extended with a 6th gear added.

Reverse is then engaged using the old heater control lever beside the handbrake and a light comes on to tell you. Must of course remember to engage neutral smile

My car has a Carrera GT gearknob (and CGT floor mounted alloy pedals) to remind me of my favourite car of all smile

Bloody brilliant video!

I totally agree it does make you think again about what we as petrolheads want from cars. The joy of driving is increasingly lost with 1600kg cars with 345/21 tyres, epas, stability control and particulate filters. Often it seems more important to kiss arse and get that latest and greatest with its deviated stitching and never drive them.

The 911K’s brief was all about the simple joy of driving, with the return of the sensory experience. My car has taken a long while but all the time Tuthill have been refining it and it looks like the wait is worth it!!!

It isn’t at all a handful unless you are absolutely rinsing it. The way you can put all the power down on a UK B road is truly astonishing and a joyous experience. We have forgotten how a sub 1000kg road car drives.

The final engine mapping will sort the flames, which look cool but yes they melt your paintwork. I am hoping my car is almost here now. Will post photos and videos of course.

The wheels have carbon rims with magnesium centres.

As Richard said on the video, the wheels (exterior) are painted though there is a small band of exposed carbon. And if you look through the “spokes” you can see the exposed carbon on the inside of the wheel.
