Agree with most of what you say, it does appear Caterham man is trying harder and 70 man is being cautious but my memory of it (can't be bothered to go back and look at relative lines 
) is that 70 man is far from using all the track and could definitely get more speed into around and out of those corners.
BTW never 'met' anyone else who also had a MegaBird so

Yeah, they're great little toys aren't they. Not a lot of fun in the rain, but on an early evening drive in the summer down a quiet country b road
A T70 would certainly make a great sequel
thats what i love about the GDt70 on trackdays, it takes them in its stride, no frantic revving, thrashing or the like. just raw speed in and out of corners, grunt all the time, brakes that dont fade
the one slight downside is 6 litre v8s are not eco friendly on track, mine is set up for cheap 95 octane petrol but i can easily do 4 jerry cans full in one day plus the tank. i am getting 4-5mpg on my carb set up on track :-)
efi versions are a little better on track however!

Why not convert to EFI then?
i converted if from efi! loli wanted a carb for the ease of set up, no mapping issues. has been on car 4 yrs without needing a tweek or a touch. on track it will use a little more juice than efi but makes the same if not more power. throttle is fully open most of the time and its got mechanical secondaries so you can hear the gurgling as it drinks it down :-)
if it was a road car then i might have kept the efi but it was a lot more expensive to get a mappable ecu and all the bits.
the carb conversion cost me about 700 quid all in at the time for the manifold, carb and msd box and i havent spent a penny on the fuelling since. i can adjust the ignition map myself on the msd box with my laptop if i need to.
also to add i have come from loads of jap cars with turbos/mapable ecus and was fed up messing about with dta/omex/etc ,, just wanted something simple which would do a job. the efi equipped cars do get good mpg on a run etc, saying that the carb drives just as well and maintains decent fuelling when driving sensibly

P.S. the fastest race lap ever around Goodwood is held by Andrew Smith in his original Lola T70 Spyder set in the 2010 Goodwood Revival, averaged a tad under 110MPH. It was previously jointly held by Jim Clark and Jackie Stewart in a Lotus 25 and BRM P261 F1 car respectively, set in 1966.
Was the T70 spyder as quick as the McLaren M8D? I remember hearing about Hulme setting the unofficial lap record at Goodwood in the McLaren with a time of 1.01, I make that an average of nearly 140mph.

Goodwood was used for testing post it's closure to races, lap records are only ever set in race conditions.The big block CanAm cars like the M8 are hugely faster than the earlier small blocks, they make same period F1 cars look pathetic.

not back in the day, they were quick for the first 2 seasons or so then the maclarens dominated.
in todays historic racing the T70s seem to do better but there are more of them about. John will probably have some better info on comparisons.
McLaren M1B is now winning more races than the T70 Spyder, performance is very similar.in todays historic racing the T70s seem to do better but there are more of them about. John will probably have some better info on comparisons.
McLaren M1C is a bit behind the T70 MK3B Coupe in terms of recent sucess, but i'm working on that one! We have to run the M1C in Masters with a 5.0 litre, which is the same as the T70 MK3B, back in period the McLarens were running larger engines, 6.2 litre was common in CanAm, but to keep things competitive the McLaren's have been pegged back on the engine size in the post 66 class.
T70 3B's ran to a different set of regs in period, so had a 5.0 litre limit, there was no limit for CanAm where the M1C raced. The Masters format seems to work very well, an M1C in Supersports spec would be a lot quicker, as that can run 6.2litre and slicks, in Masters the car is on treaded dunlop post historics.
We've had a few engine issues in the last couple of seasons that hasn't allowed the M1C to show it's true potential, when the engine has worked it's won and led races against the best T70 3B's, again these two cars are very close on performance.
My own personal preference is for the McLarens, i think they are fantastic cars and relatively easy to work with. The T70 is much harder work by comparison. I think the main reason the T70 Spyder got such a good reputation in CanAm was down to John Surtees, for me the McLaren M1B was a better CanAm car. Of course until Porsche turned up McLaren then totally dominated CanAm with their M6's and M8's, which were a massive leap forward in technology.
McLarens certainly ruled the roost for much longer than the Lola T70 in can am. saying that the Lola is the better looking of the two for me, but any of the can am cars does it for me with the brute power and also the engineering thought that went on back in the day, they could and did try anything and everything in the name of speed :-)
Did someone say Group 4 and Group 7 worship?
Those guys still race pretty closely...
Absolutely love this period of sportscar racing - the Group 7 machines were mental but the times when the grids were shared (Watkins Glen weekend 1971 for example) proved that actually the best Group 4 cars weren't a million miles away, especially when you consider the G4 cars were homologated. It's such a pleasure these are still raced for us all to enjoy.
John - I presume from the M1B/C and P34 chat that you work with Wills/Twyman? Very exciting to see the P34 out from the museum after so long. I wonder if we will ever see Roger, Martin Stretton and Mauro Pane out together in the same race? That would be quite a spectacle.
