Just seen a link to someone trying to achieve the above!! The £10k budget including buying the car is a little misleading... because the man doing it is Andy Forrest (http://www.andyforrestperformance.co.uk/) who has access to a vast stock of bits and bobs available to him and contacts who will be prepared to help the project, that will all reduce his spend compared to joe public trying the same sort of thing.
However, take a look at the link, he's going a slightly different direction with this build and not using the typical 2.0, 2.5 or 2.33 built engines to power this, but actually planning to use a basic EG33 engine (3.3 N/A engine used in the Subaru SVX) with forged internals and turbocharged to power this project.
Possible or not, it'll be interesting to follow the progress over the next month or so...

He will be using thousands and thousands of pounds of parts he has laying around though... And no VAT and no labour charges.
So budget is just not 'real'
Love Andy forest cars though. Mans a genius!

Yea, totally agree Lee... the broken dog box from his old car that he bought cheap will be repaired cheap because he's likely got replacement gearkit etc sitting around his workshop.

surely bulding a 10sec car cant be "that" hard, if thats the only goal of the car? i recon some of those drag cars you see at pod sometimes must be shed-builds and low budget?

As per Jim I dont really think its that difficult to do if you are single minded that it doesnt need to be good on track etc too, especially if you started with a big v8 and lots of nitrous.
Cool project though and im sure it will be good fun to do, and bring him publicity for his business

didnt wenny get that pink shed of a sapphire 'painted pink and goes like stink' on a budget of 10p to do an 11 sec? then break a diff...
all he did was strip it out... REALLY STRIP IT OUT! then add a few engine tweeks. surely on 10K and with a workshop like andy forrest it should just be possible. even if it just does one run and blow up :')

In all honesly we'll never know what it REALLY costs due to parts he had lying about etc and also he will HAVE to do it because if he doesnt it will be poor publicity for his company.
As an example my mates old Corvette ran a 9.9 with a 520hp SBC and approx 300 shot of gas.
If you work out that the nitrous setup was approx £1000 and a SBC of that power can be built quite cheap all you need to do is find a car to put it all in as the Vette is so featherweight.
The vette was sold for under 10k complete with nitrous and 5 grands worth of 9" he had just had fitted so you could of had a ballistic, mega reliable 9 sec car for less than 10k really.
This build is a bit of a serious version of the £500 racer we had, yes it cost £500 in total but the nitrous kit, wheels and suspension were already available to us.
Good luck to him

Although how about a forged engine and the worlds biggest shot of NOS

Gearbox lying around that 'happens' to be a dogbox or something similar and your there.....
intresting hope he does it but Grant i rekon with 10k and doing the work yourself and have mates in the right places it can b done quite easy get a v8 supercharged,then bolt a big turbo and strip the car completely nos aswell then your in with a very good chance

Haha, yea you could do it yourself... I totally agree, but limiting yourself to a car that isn't normal to see busting out 9 second 1/4 mile passes is a wee bit different to buying a mega unstressed but massive potential, V8 engined, muscle car and wanging on a huge lump of NOS?
To me (obviously the budget in my example is wildly different), thats a bit like setting yourself a target of hitting a genuine 200mph (not Brunters here Rod, just reaching 200mph.. on a road, verified by proper gear). Then going out, buying a Ferrari 550 Maranello which has a top speed of 199mph and throwing on a bit of NOS to achieve 200mph....... rather than limiting the project to a car that does 150-160mph and hasn't got the greatest dynamic design; then seeing if you can reach the target set.
Besides, AndyF trying to use anything other than a Subaru is like wearing a Turban in the shower, wrong.

Twin engined mr2 turbo could fit the bill? Not sure if its been done but a celica gt4 front engine set up and keep the mr2 mid engine set up too I would have thought could quite easily break the 10 second barrier?arent they about 12 second cars anyway due to the power and mid engine layout?Only barrier would be the four week timescale!!!
will be a awesome achievement if he does it but as said i dont think you will get the truth regards the spend,and like the gearbox if you had to buy it would cost a fare few grand alone

this should be an easy achievement for andy.
I assume a few people have read my thread where im trying to do 200mph at bruntingthorpe for £10k including buying the car, its all about priority, choose the right base car and a bit of 'out of box' thinking and it possible.
To let you know ill be making 700bhp with my car to do my 200mph, theres also another rx7 thats putting out the same power with stock gearbox etc thats running 9s so theres nothing stopping me doing this after my top speed run aswell.
money helps, but money doesnt always equal success

an rx7 is a better base car for the budget tho as there are no engine internals that need to modified as such, apart from porting, theres no cam's, crank, rods, pistons etc thats where the money add's up. and the gbox and diff will probably take the stick :P

theres gonna be a little update on it next week as its payday so now my transmission is all braced up and sorted, cooling is finished ill be getting back to sorting out a bit of safety and stronger ignition, then ill be on the home stretch i think.
But im interested in what andys doing as although he has alot of spare parts hes using for free he is costing everything on that forum to show the figures so it makes much interesting reading, ive noticed hes doing the same clutch as me ACT holds 900bhp+ for £400, great clutches!
well the stock diff wont take 9sec qtrs, they will live with 10s ok, but 9s is a bit much, for that id just get a £400 kazz diff, not sure im gonna be able to complete my car for £9600 though so i think id be a few hundred over if i wanted to do this after, saying that, i think it would be either to build my car to do 9s easier than to do 200mph at brunters as 33-35secs of full throttle is a big ask!
