I'm sure there are faster cars than that.

as Jeff says, the 3 points are all different, unlikely to find a car that will do all 3.
often notice at Aintree and Anglesey the aero drag of the 7 types really makes them struggle. some of the quick Midland Busa 7s struggle to get over
115-118mph over the flying finish at Aintree, whereas my lardy old bus does 129-132mph depending on head/tail wind. The busa 7s kick my arse at the
shorter or lower speed sprints though as youd imagine.
Simon McBeath did an article years ago *I think* in CCC (if not RacecarEngineering) with a Caterham in MIRAs wind tunnel to reduce drag. made a huge
difference, lots of cardboard and tank tape to cowl in silencer etc, and front cycle wings that came so far forward around the tyre they almost met
the floor

Was gary in his westy cosworth or del's?
Matt is mega quick too. I saw tha turbo'd dax at hardwood a couple of years back and it couldn't get power down at all.i imagine the tight
twisty bits with short straights didn't suit the car which I would think would be awesome somewhere really fast!
Surprised Gary was 7 secs behind as at anglesey he was up with the fastest cars there other than the Gould NME

Ooops forgot about Del and Gary sharing Dels car, Yes its bloody quick
Gary's old NA Cossie powered car wasn't slow either...
Mark Smiths old XE powered Westfield was absolutely awesome aswell but he's now moved to a single seater

That's a really good point, the seven shape doesn't have a great coefficient of drag!

This is an interesting comparison between a 7 (Levante) and something truly quick

That's an interesting read, with two cars that have a fairly similar power to weight ratio.
I suppose if you compared the Caterham to a more similarly priced 'production' car like a 911 turbo then it would be a different
result.
I still think the Caterham is a lot of money for what it is when you compare it to a Radical SR8, but I suppose not if you compare it to the Atom V8.

Back to OP. The question was about sevens.
Even of they have bags of aero.
Track days ARE the best thing since sliced bread, until I get a supercharger that is!
