We've got 13" slicks here, which were destined for single seaters. ( Don't ask. My son would get in strife if I made it public.  )
A bit different to the norm, and very sticky when you get the skin off, from very cold to hot.
Unlike nearly all slicks, these don't harden with use, just get a dry surface on the top after three or so days. Take the skin off, and
you've got a tyre that sticks to a smooth concrete floor, cold. Sounds like tearing gaffer tape off when you move them. They come plastic
wrapped. Getting the skin off needs some time and 80 grit sandpaper though!
Nearly every major tyre maker does slicks, you just have to be prepared to venture from the accepted standards to find what works. Tyre chemistry and
chemical formulations are as many as the stars in the sky.
Cheers,
Nev.

Ready to Roll
The running gear is now all done (apart from a geo set-up), brakes are bled and everything is ready to go. Just need bodywork (still), craning it down
off the chassis stands was a tense moment:

I didnt want to store a trailer or drive a van...
But I still needed a racecar transporter.
1995 Chevy K1500 Long Bed, converted to a racecar transporter, its a bit limited to cars with a <2400mm ( ~94" ) wheel base and very little
overhang but it means not having the storage issue or faff of a trailer and being able to drive around in something I like driving.
I think it may be the best "petrolhead" thing I have done:

Its the same, just replace "IVA" with "MSA"..... actually it is simpler but the MSA stuff is usually things that need to be
correct early in the design/build so if you get them wrong it can be very difficult to fix (see all of the ROPS debate on Uphill Racers at the moment)

I'm planning on it, if I'm not there you'll find me in a straight jacket being carted away as my brain has finally overloaded.
It's very much going to be a shakedown debut, pottering round to make sure it all works and get some pictures and data.
But then again when that light goes green...

FRont Wing & Curborough
I finished off the front wing and nose panel last night, doesn't look half bad:

Also, sorry to let people down but I wont be at Curborough this weekend. I mentioned it on Facebook but it became clear that the amount of work I was
doing was affecting my health and my family life and also making me a miserable basterd (even more so than usual) which wasn't fair on anyone.
I'm still cracking on with the final jobs but at my own pace. I'd say August is a realistic target.

Terrapin Size Comparison
I got my set of Terrapin plans through earlier in the week so thought I would knock up a quick 3D model of the Terrapin chassis based on the plans for
a quick comparison.
I deliberately never looked at the Terrapin plans before I started my project (so that I wouldn't just be making a knock off) but did use a
number of Staniforth books for reference. I quite surprised and pleased out the comparison particularly on the size and position of the chassis
tubes.
Anyway:

3D Printed Air Intakes
I've had these printed up by a guy I'm working alongside and think they are a great little finishing touch for the car. They are printed
in ABS so are pretty darn sturdy. The set comprises of two adaptors that fit into the ram-air intake of the original Honda airbox and a roll hoop
mounted air-intake. So much easier than manufacturing something from Ali' or GRP and they fit perfectly, the main limitation is the size, the
roll hoop intake is right on the limit of size in all three directions.

Debut! and some more pictures...
I have been asked a few times when the car is going to debut and if I can post some more general pictures so thought I would answer both.
I am now booked in for a test at Curborough on August 25th, hopefully its just a few last jobs to get done now and it should be ready to run.
And here are a load of general pictures I took last night:

Those 3D printed parts look very smooth and very nice!
Do you know what printer he used to make them and if he did any post processing to smooth the surfaces?

I don't really know anything about the printer apart from the fact its a personal printer and not some massive industrial thing so quite
reasonably priced.
I do know that there is no post processing, the ABS just seems to come out really nice. It can look a bit rough where support material has been cut
away though.
I have had a set of T89 Centre caps made for my truck in the same way and they look even better.

Corner Weights
Managed to get the car set-up over the last couple of nights and borrow some corner weights... pretty pleased with the results. I have been aiming at
330Kg for a ready-to-run car and ended up at 327kg with 2l of fuel on-board but the wings removed (they were driving me mad getting in the way while
doing the set-up work).
I'm mainly pleased because my car is about as heavy as you would ever build one, it has the lower cost steel pedals and coilovers, a slightly
heavier earlier chassis design, a cheap (and ruddy heavy) Jetex Silencer as well as a steel bike end can and a set of rally spec wheels that
aren't light at all. Also there is plenty of weight to be removed in optimising bolt length and weight reduction on the rear hubs.
Also despite the nay-sayers I have managed to keep the weight offset to a minimum with just 6kg across the rear wheels (without jacking the RH side
up) which I'm happy with.
I think with a little bit of simple weight reduction 310Kg is achievable for a complete car.

A couple of little bits.
Managed to grab a few moments over the weekend and the little job I managed was to remove the seized on Jedi wing end plates, clean them up and fit my
own stickers. Its a little thing but it seems like a huge step to be fitting my own branding to my own car:

Curborough Shakedown
Went for the initial shakedown and some testing at curborough today.
The car was excellent, even better than I expected. I was particularly pleased with the really predictable neutral handling. Steering, brakes,
suspension and chassis were all superb.
Only teething problems were a slipping clutch (i should have forseen this on an engine with 41k on the clock) and some overheating caused by a faulty
fan switch. Oh and the rain, the bloooooodddyyyy rain!
