I'm totally in Rob's hands at the moment Walter. With his recent premises move, I think he has a bit of a back log of work he needs to complete for other customers, but I'd imagine we could get another week in soon fingers crossed.

A lot of it is down to how much work I can afford to pay him to do as it's very much a 'hand to mouth project' and the engine and gearbox bills are starting to land as well!

Next up is to get the front and rear suspension and brakes sorted, then it'll be finishing the floor and fully welding the chassis.

I'd imagine after that we're down to systems installations and drive train....

I hear you Andy. Better take it easy, spread it out over a few months and not get yourself in $$ trouble.
So curieus what it will do on the dyno after all is said and done (of course I would

)!

next planned job on the car is Andy said the suspension.
rear is a 4 bar with lateral links to control the side loadings with room for plenty of adjustment at the front mounts of the 4 bar so we can get it set up .
front is based on 3 bolt 1303 struts but with a wishbone rather than a tca and anti roll bar.
front brakes are bug with chevy patten discs
rear brakes are corvette hubs and discs with as yet unknown calipers.
We now have a copy of sfi floor specs so the chassis can be tweeked to suit these new regs and the seat mounts can be done. once the seat is in the peddle box can be fabricated and Paul from bears transmissions can come and measure up for shifter linkage.
The dummy gearbox with the custom tail houseing is here so the front mount for the gearbox can be made up and fitted.
Webcamshafts are grinding up a custom cam for us so once that lands in the uk the case can be set up for the type 1 lifters. once that has been done we can dummy build the bottom end and work out what the pistons need to be and get J&E to make them.
then when we have a long block we can start to work out were the turbo is to sit and make up the twin scroll header and inlet system.
lots still to do both on the drivetrain and the chassis but its starting to look more like a race car with ever step we make.

Great to get an update from the man in the know.
I take it there s not much of a visual change at the moment?
Cheers.

Yeah, it looks a lot more expensive!

Wally, I'm so far in the hole ££££ it's not even funny - but I knew this before I started and I'm fully commited so it is what it is.

As for the Dyno....

I've no experience of this, so my guess is that we'll just have to creep up on it slowly and keep an eye on the knock sensors so we don't blow it's ass apart. From what I gather, the dyno guy has experience with our ECU, so that'll help keep the JE's within a few feet of the rest of the car.

Assuming we can do a decent job towards keeping the heads sealed, the aim has got to be 500 bhp at the flywheel.

The ingredients are there, the bottom end is strong enough and the resto of the components top notch and built to live with the boost, so we'll just have to chew on a 2x4 and wince...

Some more progress...

The rules for 2013 have changed where tube framed cars are concerned and now any new build will require the floor spec to meet SFI 25.4 so the floor was set up in this vein which allowed the seat mount to be finalized...

Round the back, the front gearbox mounts were designed and fabricated meaning the transmission is now set in place and fully mounted...

Above which the top stay mount was made. The 3 rows of holes along the top are so the height can be adjusted. no big holes in the front of the 2 plates as the engine breather tank is going to be built off that plate.

With the transmission now in place, the rear suspension can be started. Many hours of calculations resulted in us settling on a 5 link, 4 bar IRS system which is now under construction...

And that's us up to date so far. It's really starting to come together now and as most of the difficult calculations and number crunching is done, the rest of the fabrication and systems installs should start to fall into place.

Another few steps closer to launch.

500bhp... that not messing around!

That's the target with the motor, although I'm sure there'll be plenty of development to get there, or close.

Thing is, I'm not ready for 500bhp, so both me and the car can creep up on it together.

nice to feel improvements as they're done also, sounds a bit ghey, but you can grow together to so speak!

Meanwhile, Bears transmissions have been busy with the gearbox design and build and have just sent me a drawing of the final design for the 'Direct Shift System' which has been custom made to suite this particular application.

Nice.

I made the 7 hour round trip to Rob's today to sit in the driving seat, so Bears Transmissions could measure up to put the shifter in the most comfortable position for me, and for Rob to check the position of the pedals and steering column, now that the seat is mounted.

I was looking forwards to getting a load of pictures on my new camera, equipped with wide angle lens, so can you imagine my horror when I arrived to discover I'd left the memory card at home in the laptop.... This turn of events did nothing to help with my self loathing. Please forgive the dreadful camera phone pics that I little option but to take.

Paul from bears wondering what all the fuss is about...

Bruce (Dead Dog) who is painting the car turned up to help Rob take the piss in a cruel tag team style effort....

I wondered why Bruce was so keen to get a picture of me in the car - it was only later I saw his bonnet graphics. I wasn't so much angry as disappointed.

It's starting to feel a bit 'real' now.... that's a nervous smile.

Rob had the rear wheel and tyre mocked up in it's final position...

As the body has been channeled a good few inches and the gearbox raised a fair bit, we'll need to cut the rear wheel arch back for adequate tyre clearance and mount the over-size rear wings higher up the body.

I had my first proper look at the rear wheels today and I must admit, they're growing on me. Slicks could use some air though!

The front end is roughly in position, but may need trimming at the bottom once the final ride height is set, but there'll be a decent sized splitter there anyway. A bit like when the Queen visits, Rob had clearly been busy tidying up for my arrival....

Action stations...

Whilst I was down there, I took a foam block that I am sculpting to the exact profile of the roof so I can make a wooden 'buck' of the roof to mould my rear spoiler round to ensure it's the exact correct profile.

As I say, sorry for the terrible pictures, but that's pretty much my visit wrapped up. The next installment should see the car getting dangerously close to being a roller....
