Went out to test my new camera, almost stacked it at 3:50 :roll:

Didn't think I was going that quick but I guess the combination of brand new rear tyres and cold road almost caught me out :eek:

I do love footage on gopros though and well saved Mr Hobbit I suspect the sun blinding you won't of help lol

I somehow had time to think, oh feck bank, glad I have a cage. lol

Do need to sort that out, might cable tie on some sun visors lol

It is a ****er without visors sometimes! It looks like you lift off as you exit the corner slightly, that is exactly what happened to URY my first Sri just with a more catastrophic finale lol.

Are you sticking to the speed limits? It's hard to tell as the engine hardly has to work! Go pro works well though what one did you buy? I liked the look of the iPhone go pro stand (as its cheap and the only time I would use the video camera would be in the car).

Hobbit
16-01-13, 05:52 PM
Wouldn't be silly enough to post a video of me breaking the speed limit.

Its a GoPro Hero, with GoPro cage Mount. Got it set to 30 frames per second as that narrows the field of view, when set to 60 FPS you see more inside the car than outside. Doesn't seem to affect the quality too much though.

ps doubt I was lifting at that point in the corner, just holding steady. Should've grown some balls and floored it mid corner. lol

Didn't think so, looks good quality from here.

Real pros spin the wheels up mid corner lol

Can you adjust the density on the camera? Couldn't see all that much outside. And the dangly thing on the mirror got in the way lol


[edit] and dude, photobucket, srsly! Have you not heard of youtube? lol

Steady, only just worked out how to adjust frame rate.

Clearly I don't drive it enough to let it bother me. Will remove it before the track day though. Is a glow in the dark air freshener which neither glows or smells lol

Trust me, the camera does nothing for the true sound of that car, on full chat, you seriously cannot even hear yourself speak (and no im not joking either)


Lucky save on that one dude, ive known a lot of peeps be caught out by new tyres and bin their cars completely :eek:

I'm putting it down to the tires being new, like a few miles old. The back end has always been a bit lively, I should put some ballast in the boot but seems backwards adding weight to a track car.

It is hard to make an inboard shoot look as quick as it feels.

Is your steering wheel in need of straightening? There's quite a lot of yellow in the interior; why the taxi no smoking sticker?

Hobbit if you could, would you want a setup where that exact same drive meant never having to moved your hands from the 10 to 2 position?

Hobbit
16-01-13, 08:40 PM
So many questions.

The wheel is slightly to the left iirc.

I like yellow.

No smoking sticker was on the dash from the car I got the dash from, seemed ironic considering how easy it smokes its tires.

Less steering input would be nice. Could do with a quick rack.

Hobbit you need to change the setting on the Gopro so it will not white out so much.
Its in exposure setting, set it to spt this is a lot better for filming in the car looking out

Do you have a spare wheel in the back? if not then its a nice weight gain for the rear that actually serves a useful purpose so you don't have to feel so bad about adding it.

What suspension set up you got on th back end and is th back geometry standard?

Mieran

This car need a quick rack and a flat steering wheel

Hobbit
17-01-13, 03:10 PM

Bilstien shocks and 40 mil springs. I know I should go coilovers but i prefer the softer set up.

MK999
17-01-13, 03:25 PM
Coilovers will probably help it a lot tbh, no one seems to consider that the separate spring damper setup is less stiff in roll than it is in bump (assuming equal displacement of both wheels simultaneously, which is going to be true at least some of the time, and assuming it's not tbh, is just considering your car in roll and in roll in a different way) either way you look at it, it's the opposite of what you want.

It might feel better on the softer setup as it is, but it might actually prefer a harder setup, seeing improvements all round on coilovers.

Happy to chat about the dynamics of it in PM if you want.

Hobbit
17-01-13, 03:52 PM
I'll pass cheers.. lol

I might go coilovers one day, but I just want to spend the money doing track days this year. Also Mr Reynolds took it round Combe and said I'd built a decent (albeit slightly soft) car. :)

phunkynova
17-01-13, 03:58 PM
Sorry to say this but you made the car step out as you backed of the power with steering lock still on causing the back to step out.
I really did not what to point this out.

Hobbit
17-01-13, 04:02 PM
^ crack on, adjusting my driving style is cheaper than all the other suggestions. :thumb:

Don't think I backed off though. Was trying to hold the power flat.

drifting the nova like a king lol the exhaust/engine sounds mega in the vid by the way

phunkynova
17-01-13, 04:11 PM
If you watch the video keep an eye on the steering wheel and listen to the engine note. you have left lock on and then there is a note change, then you must react to the over steer

phunkynova
17-01-13, 04:18 PM
The killer was the extra spurt of gas you give half way around the corner then back off , it really upset the balance of the car.

On b roads coilovers is definitely the wrong route imo as they are to hard

I though exactly the same dont worry.
The blip mid corner caused lift off oversteer via weight shift as he had taken it tight aswell

If you haven't already (it doesn't look like it from the video) turn on 'Spot Metering' on the GoPro.

If it ain't broke don't fix it? :p Always a bit intimidating to play with something that works, but tracking something that you find fun sounds like the way forwards :)

I just *HAVE* to play with things myself lol I'll probably never get near the limits of mine because I'll be changing things left right and centre :p

Always been confused by this thinking tbh, see it all the time, yet, you can put 100lb springs on and valve coilovers accordingly... How is an installation method, too hard? :confused:

Hobbit
17-01-13, 05:54 PM
Cheers Iain, Phunky mentioned that a page or two back. That was the reason for taking the vid... Ado do you have yours set at 30fps to narrow the field of view.

As for the lift off, I was using 5/10% throttle so there wasn't much I could lift off. Also the slide started mid corner (before you notice it on the vid) so the change in throttle could me reacting to the slide. Also surprised no one has commented on my over correction. lol

And bare in mind the road was untreated, barely one 0 degrees C and the tires still are uber new.

Whoops sorry skimmed through the pages but didn't see anything to do with GoPro settings.

Just checked and I'm running mine at 720@25fps and wide FOV. Couple of reasons, I'm using old laptops to edit them (too pikey to buy a new one), they only ever get uploaded to Youtube and I like to have smaller file sizes so I can fit a sensible size memory card and not worry about running out of space on a track day.

burgo
17-01-13, 06:24 PM
Ok unless you want to spend more money on coilovers than the car is worth then they are the wrong route imo.

MK999
17-01-13, 09:35 PM
I'm not sure what coilovers you were thinking, but most/many people seem to run Gaz, who will spring and valve a set to your specifications, even set body lengths as per Benns. I don't think a trackday or 2 worth of cash (4-500 for GHA's) is a huge investment for a track car myself? Depends really what kind of budgets you're working to I guess, but then suspension and tyres will net you the most gains (in terms of performance and/or enjoyability of the car).

Thing is a set of coilovers optimised for b roads wont b ideal for trackdays and vice versa.

MK999
17-01-13, 09:51 PM
But then neither would separate spring damper. I've just never understood the complete aversion to coilovers because they're 'too hard' when you can spring them at whatever rates you like, ok the damping is gonna be slightly harder to fix if you're looking at specific kits, but then if you're not looking to set it up in a specific way it's all swings and roundabouts anyway, and there's nothing to suggest they may actually be damped any harder depending on the manufacturer, or that the adjustment range doesn't move far enough to be ideal for what you want.

The main gain is gonna be the fact that on the rear you haven't got the springs sat quite so far inboard on a rear beam, so it goes a little way to being a more idealised setup where the roll rate is higher than the bump rate, rather than the opposite.

Although I understand it really comes down to budgets and specific setups, and in certain cases, i.e not having the cash to outlay on a customised set like Gaz and working only with whats available 2nd hand maybe, the options available might not be suitable... The blanket opinion that coilovers are 'too hard' always struck me as a bit misguided and the lack of tunability in a separate spring damper being 'too...' anything at all would outweigh that anyway imo.

Hobbit

I dunno, the dirty great v6 gives me plenty of enjoyment and performance.

And as for Gaz, I wouldn't touch them with Edd's ten foot barge pole. I had a set replaced under warranty after a year, and the guy from Gaz tried to get out of replacing them by saying they weren't really for road use. Strictly track. Which I found a bit strange when I specifically asked for a fast road set up when ordering them.

MK999
17-01-13, 11:15 PM
fair enough, different strokes and all that :) Always found Gaz pretty helpful when I've spoken to them about anything, but I've never lived with them for over a year. Main bonus is the customisation they offer at that price range though, most other companies just wanna sell you what they think is best for a standard car.

This explains a lot. I wouldn't think about going for a b road blast is such conditions unless I had uniroyals or similar winter tyre.

Coilovers don't have to be "too hard" at all.

All that's wrong is having too short / stiff springs / hard damping / low ride height for your preference. Ever notice the rally boys on loose surfaces with jumps run a 12" spring & 4x4 ride height; think that'll be uncomfortable?

I clearly have a larger set of testicles... or a smaller brain.

As per Burgo's post, I don't have a WRC budget to spend on suspension.

Also, if I was trying to build the best handling car in the world I'm not sure I'd start with a nova. lol My car is all about cheap thrills, and I doubt you could go much quicker for less money.
