Chasing an Ariel Atom, again.
daveb666 - 21/4/15 at 08:53 AM



Second trackday in 2 weeks, same Ariel atom that I can't catch but then his slightly slower mate came along LOL.

HowardB - 21/4/15 at 09:44 AM

nice

daveb666 - 21/4/15 at 09:46 AM

LOL, just found this - https://youtu.be/vn1OFOOvUj0?t=30s from the Mazda.

Great video, 1st Atom is damn quick.

cracking video quality!

coozer - 21/4/15 at 01:31 PM

Excellent, makes ya smile

Bit more power required???

kingster996 - 21/4/15 at 01:57 PM

Nice one Dave!

Great shot from the Mazda seeing the three of you fly past him

coyoteboy - 21/4/15 at 05:01 PM

you just got a cone filter on the inducer? that sounds awesome!

David Jenkins - 21/4/15 at 06:16 PM

Those atoms are hot out of the corners, aren't they!

big_wasa - 21/4/15 at 06:36 PM

But to say the Locost was built by a man in a shed, fooook me is it rapid

big_wasa - 21/4/15 at 06:38 PM

So what else can't you keep with on track ?

bi22le - 21/4/15 at 07:08 PM

What engine is that Dave?

400 per tonne I am guessing it's around 220 bhp?

daveb666 - 21/4/15 at 07:13 PM

Thanks for all the nice comments guys.

The engine is a ca18det on stage2, so 262bhp exactly (has been RR). Its a 20year old engine of unknown condition so I don't really want to push it anymore really. A custom remap would see 280+, maybe. Not sure of weight but its at least 620+ I would think.

Warren - you have more of a garage than a shed :-p Whatever its a great car he he. On the day I only let the Ariel's passed, that was it I think. The comment on the Mazda's video says it all really lol

Coozer - not more power needed, better brakes! The atoms pull so well out of the corners as they're both supercharged, I'm sat waiting for the boost :-(

What camera system are you using?

daveb666 - 21/4/15 at 07:44 PM

GoPro 3+ black edition. 1080, 60fps. Was an eBay bargain.

dilley - 21/4/15 at 08:09 PM

Do you think the atom is a better handling car or just faster?

daveb666 - 21/4/15 at 08:25 PM

Both - less weight, more power and hundreds of thousands in R & D

jonabonospen - 21/4/15 at 08:38 PM

Where was that? How much?

And do you drive the Locost there and back or are you taking it on a trailer?

Sorry for all the questions but it looks ace, and if one day soon I get my Mac#1 on the road I would love to take it somewhere like this

I trailer mine but I have a habit of breaking stuff LOL

CosKev3 - 22/4/15 at 04:09 AM

Noises from your turbo sound awesome

Is the microphone under your bonnet?

daniel mason - 22/4/15 at 05:50 AM

It does sound rather epic Dave!
Upgraded brakes,decent damping and some good rubber should see a very fast car indeed! Especially on a larger circuit where you can really stretch its legs

vtecmike - 22/4/15 at 08:25 AM

Nice vid , car goes well !

Ive got a haynes roadster with a ca18det , what rad are you using as mine runs really hot


Cheers

There's a few questionables on the Atom for something with £100Ks in devel, from what I hear.

daveb666 - 22/4/15 at 09:02 AM

The microphone is inside my cone filter, it is loud anyway but without the external mic you just get wind noise.

Daniel - I'm now on "sticky rubber", not 888s but semi slicks none the less. I haven't got the funds for protec or similar dampers so the Gaz will have to stay - brakes are a good possibility though so will be changed asap.

Vtecmike - its an ally one from eBay, I also suffer from heat. 6 laps at Blyton and I need to come in to let it cool. I'm adding flared panels next month to try and let the heat out faster. Blyton problem is there are no long straights so you never really get proper airflow.

enjoyed the id dave, is it water temps that are your issues?

Dave, someone recently mentioned their turbo setup stalls when off throttle, was that your car? If so, is it worth coming up with a solution for that? It would certainly help with the boost delay, and it might give the turbo itself a few more years service.

coyoteboy - 22/4/15 at 05:30 PM

Errr most turbos stall off-throttle if there's no bypass/BOV, don't they?

Mog72 - 22/4/15 at 06:53 PM

Really enjoyed that video, usually get bored of track day vids within a minute or so in !
Car sounds great too !! My Westy is just over 200bhp... Vids like this make me want more power !! Can't push my silver top anymore though without spending big bucks!!

theduck - 22/4/15 at 06:53 PM

Slightly off topic but which external mic do you use? Putting it in the airfilter is genius!

daniel mason - 22/4/15 at 08:06 PM

We have similar line through bunga bunga. Others use it differently! But yours is much better through the final turn! Lol

I had the same problem, with a 170bhp zetec. Just couldn't warrant throwing money into an engine that's 'meant' to be N/A when I could buy a turbo one already done.

I think so - don't have an oil temperature gauge so not exactly sure :p Water temp rises up to around 98-100 after 6 or 7 laps. If you do have a lap off boost it quickly cools down; the T28 is water cooled so I'm guessing that my rad simply can't keep things cool enough.

I've not noticed a lag, I was contemplating getting a recirc but the CA18 doesn't have one anyway so I'd be altering how the engine is usually plumbed together, plus I like the noise

You'll also need an extension lead for it.

That was running about 300BHP....since gone from 0.7Bar boost to 1.3Bar and 397BHP so it is a little more adaquate now.



This was the WSCC sprint last year....extra power but I'd ruined my soft tyres so I was running cold mediums which made it errr....interesting.

coyoteboy - 23/4/15 at 04:28 PM

That inlet temp is pretty high!

jeffw - 23/4/15 at 05:23 PM

I think that is because you don't normally see inlet temps during these types of events. You will find that is pretty typically on boost....

daniel mason - 23/4/15 at 07:38 PM

A new set of boots would Definately have seen you in the sub 70s laps jeff.
Makes me wonder how much under 65 I could have gone with some decent tyres and a helmet I could see out of

does it keep rising? 98-100 isnt really high i dont think my elise gets up to that on track after 6 laps

mine is water cooled also and ive fitted a coolers external to the car on both sides, oil on one side water on the other that has helped massively with temps on both water and oil

jeffw - 24/4/15 at 11:13 AM

110 or higher would be an issue, 100 is fine.
