Vbox and Dragy stats

[RUSSELLM]

I finally got chance to use a Christmas present (Dragy) last week, all be it on my daily commuter/tractor.

However, when looking on the Dragy app, I came across this from a 4.5 Cerbera




8.6 seconds 100-200, seems like a great effort.

Looking at the acceleration/speed graph, it looks like he started in 3rd gear and just did the One shift.

I was thinking at 100 kph, you’d have more power on tap in second gear, but it’d be down to how much time you lost on a cross box gear change, versus the straight change from 3rd to 4th.

I’ve seen the stats for the LS powered cars before, but are there any other GPS stats for the factory engined cars, lurking about ?

Edit... Just checked the Dragy profile, and this maybe a 4.7L

I think 3rd on mine is about 15mph per 1k revs, so I’m changing gear around 105 mph.

That graph looks like he changed gear around 100 mph (160kph)

Exactly the same figure as the M2 CS with 450 bhp, and a single manual gear change.

London based, according to the profile on Dragy

[RUSSELLM]

I seem to recall my gearing is 7, 11, 15, 21, 25 mph per 1000 revs in each gear.

I think 112 mph is the most I’ve ever got from 3rd gear

Ha

Is it a standard 4.5 ? Your Dragy profile mentions 4.7, so I wasn’t sure if it was a typo.

I’ll try a 100-200 myself, once I get an MOT

It’s a regular 4.7 mate, defo try the dragy it’ll be good to see what times other cerbs and t cars can get.

Blimey.... Just seen your latest results

Looks like you held onto 3rd gear longer and changed up at about 110 mph.

Have you tried any runs using a 2nd gear start ?

Gear change looks like it saps about 0.6 of a second, so in a half decent auto, that’s a very low 7 second 100-200

Who was the engine built by ?

7.7 seconds in excellent.

Mine’s a near enough standard 4.2, but I’ll try and get a run done in June.

[RUSSELLM]

Thanks.

What’s the spec of yours Gruff ?

I was thinking a 4.2 with 360 bhp will be about 10 seconds ?

is there any way to view the results without buying it? we can read the words but not see the results tables - some screenshots of peoples runs would be great

The Dragy app is free Jules.

Once you’ve downloaded, you go into ‘me’, select ‘unit’, then select ‘metric’

Then go to ‘Leaderboard’, scroll down to see the various car manufacturers, and click on one. You might need to select ‘+’ to add TVR from the list.

You can then select 0-100, 100-200 etc from the list.

0-100 (or 0-60 if you go none metric) only has 1 TVR result, an S3.

100-200 only has DMW’s figures, so I presume Gruff hasn’t posted his to the leaderboard or has used vbox etc

If you click on DMW’s Dragy profile, you can see his previous time’s too.

The actual GPS dongle, direct from Dragy, is about £120 delivered.

Managed a couple of runs, that I’d forgotten about

0-60 is over a second slower than my bog standard 335D . Cerb’s a nuisance to launch though. I had a 4.4 at York Raceway, but I suspect that included rollout.

Crap launch aside, 0-100 mph looks like 10.7 seconds

100-200 is 10.55

Both manifolds are cracked and due to be replaced at the next service.

0-110 mph with rollout looks like 12.91 including the gear change to 4th, which looks about right to me.

I think I did a 12.7 1/4 mile at York, but that was holding onto 3rd to get a time.

Looks like my 335D is quicker from 0-90 mph, then the Cerb flies off
