The car seems awesome. Hoping to have a go at a few sprints next year myself.
I like the layout of the data overlay. Mine just gives text and data for the moment. The mini dash looks good.
Do you think it'll help you go quicker when you know how to read the data properly?

0-60 off the start in 4.51 secs. Maximum speed 112mph, max lateral G 1.27 max brake G 1.3
Certainly helps when you analyse why one run was faster than another.

Its good to know. The one i'm using comes with software thats used at full blownle-mans race teams etc, almost seems to do/show too much.
Seems a little mind blowing at first, once i've some proper runs to log and compare it should make more sense. Much like yours I imagine.
How much does a days sprinting cost? Not including fuel/getting there.
Sorry for the questions.

The Honington entry fee was £65 which is on the low end of the range of fees. It ranges from £65 upto £170 for somewhere like Brands Hatch.

I did this Sprinting "how to guide" for another forum. I have only been doing it for 12 months or so which means some of it may not be
accurate depending on which class you enter.
1. A car (pretty obvious):- Lots of different classes but I'll assume for the sake of this that we are talking about a road-legal kit car. The
class of this is specialist sports cars and normally has all the Lotus Exige/Elises & the kits in. Typically split at 1700cc and therefore I run
in the Over 1700cc class whereas a 1000cc BEC would be in the under 1700cc Class. I have ended up competing with a 7.3l Ultima! As the car is road
legal you will need to prove Tax, MoT (if required & insurance when you sign on. The car most be road legal in all respects and you can use MSA
List 1b tyres (R888, A048R etc etc) and you can also use the standard road tyres listed in 1a but you will not do very well unless it rains.
1a. Car Scrutineering :- They will check the car is safe which included FIA harness if you are using harness it must be FIA/MSA approved and in good
condition, they look under the bonnet (you need to have a yellow earth lead to the battery for easy identification). Although not required in a road
class if you have fitted a roll cage it must meet the MSA requirements, same with master electrical switch & manually activated extinguisher. You
must also identify how to turn the car off on the dashboard.
2. Clothing/Helmet. You will need a Snell SA2005 or better helmet (open cars required a full face lid), a MSA approved and in-date suit and approved
gloves. You don't need boots or underwear but it maybe wise to wear them anyway. First time you compete you will need to pay £1 to the
scrutineer for "MSA approved" sticker on your helmet.
3. License. To compete in a road-going kit car at Sprints or Hill Climbs you need a MSA Non-Race National B license. The cost is £38 or so and you can
apply online at http://www.msauk.org
4. Club membership. You need to belong to a MSA approved club. There are loads of these around but I belong to Sevenoaks & District Motor Club (
http://www.sevenoaksmotorclub.com/ ) & also Tunbridge Well Motor Club ( http://www.twmc.org.uk/ ). Cost is about £20 and it allows you to enter
their series.
5. Sprint Entry. Normally the Regs are published a few months before the event and you simple fill in the form and send off your dosh. Small airfield
sprints are around £65 and ones on proper circuits can be upto £170. The bigger events get booked up very early so be quick.
Your first sprint
Preparation
Check your car over, make sure everything is connected/tight/bolted down. You will need a timing strut (made and fixed as per the MSA Blue Book, to be
fitted on site), some numbers (or black tape) to match your entry numbers (remember to do this once you arrive at the venue not before), your
clothing/helmet, a few tools and chair/drink etc.
Turning Up
Be as early as possible as this gives you the time to sort things out. All the instructions will be on the entry information sent through to you.
Typically the following happens
a. Turn up and park in the designated area
b. Sign on.....remember all you bits of paper (Insurance, V5, MoT, MSA License, Club Membership card)
c. Fit numbers and timing strut
d. Take car/self/kit to be scrutineered.
e. Walk course (watch flash gits with push bikes do it in a few minutes while you walk round)
f. Drivers Brief
Competition
Normally sprints consisting of 2 practise runs and 3 timed runs. This is typically done in number order do make sure you are ready to queue up, in all
your kit, when your class is running. After each run all the times are printed up on a board somewhere so you can see how much in the lead you are
Prize Giving
After the event is finished you will need to hang about to pick up your Fastest Time of the Day trophy (!) or applaud the winners. Normally a pot for
1st & 2nd in each class.
Once it is all done you need to take your timing strut and numbers off the car before going on the public road. This is the point you start planning
the next time
It is great fun and I would recommend anyone who fancies it to have a go. Anyone who can drive a car on a trackday can sprint it....
Feel free to ask any questions and I will attempt to answer them with my limited experience.

Cheers Jeff.
A few more questions....
I take it my 3.2 engine would put me in the same class that you're in then?
How hard do you find it on your car?
With the harness do they have to be 4/5/6 point ones?
What also appeals is the amount of run-off for when I run out of talent, would you say there's normally quite a bit?
I've got new toyo r1r's fitted, they seem to have no problem with cold grip so I guess they'd be ok to use?
Do many people drive there in their or is it a motor home with F1 trailer type thing?
Thanks again.

You would be in the class with me (over 1700cc). Because it is very short runs it tends to be easier on the car than say a trackday. Harness can be
whatever you like but I would suggest 6 point would be best. There is normally a fair bit of run-off although there are a fair number of cones to
hit. R1Rs are listed as a 1b tyre so they would be fine. You may find that R888 last a little longer.
Most people turn up with their road-going cars on trailers so I am unusual. On Sunday I travelled 120 miles, did the Sprint (came 2nd in class) and
then drove 120 miles home again....which is in the spirit of a road-going class The problem I face is that most trailered cars are on much softer
rubber than I can get away with on the road so they tend to have an advantage in that respect as well as only running the minimum amount of fuel for
each run.

Many thanks again.
I'd be a drive to track type person too. I just need to find a club around the Lincs/Notts area now to go along to.

Look on the MSA website for local clubs that do Sprints
http://www.bordermotorclub.co.uk/
http://www.nottinghamsportscarclub.co.uk/
Both of these fit the bill
