Santa Pod

Looking to break into the 12's this year. Had a best of 13.1 any ideas of how to knock 0.2 off?
some of my attempts!

Check the weather and wait for a stiff tail wind :-)

At the risk of stating the obvious, two things spring to mind:

Weight. Get rid of everything you can.

Tyre Pressures: Drop five psi out of your driven tyres and put another five into your non-driven ones.

But I am sure you already knew those.

Glad the bug has bitten,

On my 13.1 run i had the rear bench out, rear plastics and carpet out from the boot. Still had front interior in though. The Cars four wheel drive, i did play about with pressure. I found that higher pressure was better, dont really get and wheel spin with it being four wheel drive. Lauch it off the line about 5.5/6k. Tempted to up the boost to 1.3 bar but dont want it going pop!

[TotalControl]

IIRC, 1.2 bar should be fine. You may want to do some research on that though.

[mrGTFour]

Ive changed to liquid cooled charged cooler system to a air cooled front mount intercooler with 3" pipe work taking a short clocked turbo pipe route. Il bump it up to 1.2 bar and see what it does, may go up on the 15th weather depending

Yes.

Go and run at Shakey.

Hardly ever a headwind like the Pod and you won't be going uphill either.

[mrGTFour]

Santa pods up hill?! I know theres always a headwind but up hill!!!?

[jonermart]

Definitely uphill (with dip in right lane) - discussed at some length last year.

Looks like you're shifting in the traps from what I can see from the in-car on the 13.2. Does it hit a hard limit in 3rd if you don't shift? If its too long on the limiter for your liking, maybe a set of wheels/tyres with a slightly larger rolling radius might be enough to just give you some longer legs, to save that shift.

For the amount of power you're making according to the terminal speeds 13.1 is more than acceptable. You're down in the 1.7s to 60ft and I don't think you can expect much better than that really and you must be doing everything pretty much right off the line, so it is likely down to just needing to make a little more power or move less mass.

Good, dense, cool air could quite possibly do it for you if you can make what did on the 13.1 a repeatable, consistent routine and dependent on the atmospheric conditions during that run.

DON'T FORGET the importance of staging as shallow as possible. Stage in two motions, roll to light top bulb (pre-stage) - stop - creep inch by inch until full stage bulb just lights - stop dead - do not let the car roll even an inch before the tree runs and you drop the clutch. This allows you to use all the rollout in your front wheel/tyre to gain the maximum rolling start before the elapsed time clock starts. Of course this means you'll get a crap reaction time but we don't care about that only the E/T.

Do you know what you inlet air temperature is after the inter cooler verses before the inter cooler?

Or dare I say go to York.

The lowest track above sealevel and a consistant startline.

+ with 4 wheel drive you are more than capable of the entry and return roads

[mrGTFour]

Thank you for all the replies. Seems like a change of venue it is then! Id be happy with a late 12, tried at Santa Pod but just cant get it. Shakespeare raceway requires a helmet, does york?

Yes a helmet is required at York.

If you're running 12s, you should be wearing a helmet regardless of whether or not the track requires one. Just MHO...

[dbv8]

I would wear one if only to not offend the spectators.
I drive a soft top and have a roll bar so its a definiate for me.
I dont see why the pod allow without.

[BennettRacing]

Think its been said but your easiest/cheapest option is weight.

How far you want to go on the other hand to get your 12 is your call.

I had a mini years ago that I got hugely obsessed with weight and got it down to 512kg but I removed EVERYTHING that didn't need to be there and I mean everything.

With the little screaming 1380cc A series me and my old man built it was pretty quick.

In a car like yours there will be so much you can remove but again depends how far you want to go.

[dont know]

Luke you got anything left off that Mini? after a good head and cam etc.

Nah long gone - was when I was 17-18

Bloody good little motor!

You building one?
