Not finished the kit, but my previous modified cars Ive trusted to the limiter in top (or aero) - around the 140 mark.

If I didn't trust the build I wouldn't drive it. I've had 230kph on the speedo (matches satnav) more than once. I'd worry more
about throwing it into a corner hard, rather than just going quick/straight, as there's a lot more things being stressed... if I was going to
worry.

With most if not all cars, including my MK Indy, I've taken them to as fast as they'll go. As Adi says I'd worry more about corners
than straight line speed.
ETA...thinking back the Seat Leon Cupra TDI was the probably the quickest one and rock solid flat out. The brakes did fade a little under pressure
though 
ETA2...When I say the brakes faded so also did the clutch after I (rather smartly I thought) tried 2nd gear start pulling away from the lights. I
furged it would pull away OK and I'd reduce the no. of gear changes during acceleration. In retrospect the smoke, smell and lack of swift start
gave it away that I'd given the clutch a hard time

158MPH on the GPS at Goodwood. A little bit faster at Spa (165MPH) but that is the rev limit in 6th.

Hits the rev limiter at around 140mph
My only concern is the engine going bang.

I'm not really interested in going fast. I just like acceleration, in any direction.

Ive never been able to take a car above 120 before chickening out.. so at a guess the Ginetta will be the same once shakedown is complete.

At 100MPH+ you're going to get badly hurt in any car if it goes wrong (well maybe not in a McLaren Honda F1 car...) so at least in a
'seven' you actually feel the speed more than in a tin-top.
I remember my very first drive of more than a few miles in my Locost was a 140 mile convoy with the local car club to the David Coulthard museum in
Twynholm. Unfortunately my speedo magnet parted company with the propshaft within 5 miles so I don't know officially what speed we got up to.
But rumour has it that it might have been around 95 (not sure whether that was MPH or KPH of course...) and I must admit I was very mindful that I had
personally welded the chassis, suspension arms and steering column together! Since then I have seen several pictures of broken/bent wishbones or
failed brackets so it's definitely something you need to be sure is properly designed and fabricated.
As others have said, I'm more likely to be concerned during hard cornering and braking than going fast in a straight line. I think it's
important to do some stress tests in a safe environment (track, private road etc) to test for obvious weaknesses and then get an experienced MOT
tester to check the car for signs of structural issues once a year plus of course your own checks more regularly. My car is such a simple car that my
MOT tester, who is a good friend and fellow kit car builder, is able to spend more time than usual on checking the structure, suspension, steering etc
as there is little else to worry about.

Getting hurt is true - there's not much driver protection in a 7 type car!

I worry more at 70 on the M25 than as fast as it will go on a trackday.

My speedo only goes up to 120 but a chap in an ultima clocked me at 150 down the long straight at Bedford . New car has no roof or Windows so a head
wobbling 120 is about as far as it will see

I had the prop shafts come loose on the limiter in 6th on track. I lived and learned and have been faster since getting it sorted and adding a prop
catcher!

Crikey!
I've only managed a paltry 115 so far, but wasn't at all worried. As others have said, if I wasn't confident in it, it'd be
in the garage until I was.
