Right, took it out for a proper run on Saturday since fitting the new fuel tank (I'll update with some pictures later).

It's fast.

Really Fast.

Noisy like you wouldn't believe, not just like a TVR noisy, but no sound deadening, machine, hot, gearbox, diff noise.

It's great!

It's also very hot.

I need to get it properly geo'd as the caster angle doesn't feel quite right and I think I've over estimated the spring weights. It's like it has no springs at all, the suspension doesn't really move much. I'll give it a few runs on the track and see what it's like before changing anything though - it might turn out to be perfect for competition.

I think it would cope with slightly taller gearing in the diff, again will try it for a bit and see.

It was the members open day at Prescott yesterday, a great opportunity to do some (un-timed) shakedown runs:

Warming up:

Bit more welly:

It ran really well with only a handful of things to work on:

1) It needs more grip at the rear, it's running the road-legal Yokohama semi-slicks, I need to more to full slicks (preferably 9" wide on the rear) ASAP
2) The quick rack isn't quick enough; I'm losing speed/time on the hairpin bends as I'm having to go hand over hand
3) It really does need proper geo'ing and corner weighting
4) There's an annoying noise as (I suspect) the remote selector of the gearbox is just contacting the body shell under hard load

The tune is still pretty mild at the moment, perhaps 270 bhp and I'd guess the weight at about 900kg - so around the 300 bhp/t at the moment.

The torque is what's making it so quick, the curve feels so flat and with so little weight to move it just picks up like a monster.

Love the sound. Loads of low-down grunt is good for hillclimbs.

That's what I liked about my Westfield. 125bhp with 600kg obviously isn't a patch on your Triumph, but it's such an unusual feeling of immediate acceleration.

Just seen that a (very) quick rack is £420, ouch!

I wonder if I can shorten the steering arms without pissing up the Ackerman angle too much...

Yes combined with one of these roadkings for easy wheel palming action

I've ordered a 2.5 turn steering rack and also a set of mounts for the anti-roll bar that moves it forward 14mm. This pulls the track control arms forward also, this increases the castor angle, which in turn will help with turn-in and return to centre.

Exciting!

Picture of the new foam-filled fuel tank, the pump now sits under the boot floor, fed by a swirl pot built into the tank:

I'm seeing a lack of wires, is that clear pipe on the right in the pic your new fuel gauge?
