yeah Mark, 15's will be lighter and imo the car handles better on them on track. You have to use Dunlops? That's a random reg, but they probably sponsor it and make that a requirement I guess. These are just as good as r888's. Not sure what their longevity is like though. I'm sure they would last longer than slicks though. It's all doing to depend on your fuel load at the end of the day. Any thoughts on tank size and mounting/position yet?

Chris and Nicks cars look nice. Are they fully race spec'd DIY jobbies? You might struggle if you're using them for spares though as a few things vary on the ph1. At least you got the 182 without cup packs, so suspension and hubs are the same. I think the drivetrain is the same also, if not very similar, but don't quote me on that.

Even though I did enjoy the build.If I was asked to do it again,the answer would be a big NO.

Cool Ill go with 15's then when I need them. Just stripped the engine today and subframe and took the lot to the powder coaters
Should look nice when done. Need to tack in this Oreca cage next, anyone know what the large plates are for? Floor reinforcement underneath is my guess?best

PS
Nick and Chris's cars are home builds like mine.

That pic has given me some ideas for a switch panel and dash thanks. As for buying it yes I could have but then I would not have had the enjoymnet I have had over the past few days working on my project or the lessons im learning from doing that either. If I bought anything it would be This
When I have some experience I will.

We have the R-Sport switch panels in stock as we've swapped so many out for membrane panels now.
If you buy an X85 CC car you still need to find 15K - 20K to make it an endurance car so its not as cost effective as it first seems. There's an interview between VBH and myself floating about somewhere where I discuss the costs of a proper endurance X85 but summing up to run it as a pro car for a 24 hr it's £30K of costs and another £60K to build one from a new X85. A standard X85 is not a competitive 24hr car unfortunately.

Slightly more irrc. It would be better to get a custom one (can't think of it's name, but the bit that's got teeth on it
) to reduce the LTL slightly to put with the manual rack.Can you do me the dash too?
The dash is very limitied, it's a crippled MM DDU unit so doesn't have 90% of the functionality of the retail version. It's also TFT so you can't see it in direct sunlight. Much better option is the GEMS OLED units which are fantastic and we have used them in an OEM and two motorsport projects last quarter with great success.
Regarding steering rack etc. best bet would be to use the DCI rack and fit it out with a DC Electronics EPAS system to provide power assistance. We've found them extremely reliable in motorsport use and you WILL want some form of PAS if you're doing 2 - 3 hour stints!! You'll have slightly more lock to lock but with the EPAS you still regain the ability to "chuck" the wheel to catch an oversteer moment LOL
good luck with this, would be interesting to see how it goes, as some have said deep pockets will be needed to achieve the 250 - 200 bhp your looking for without boost, but then again youve got an aston so your pockets are deeper than most and if your sharing the costs out between 3 or 4 of you its not too bad. all looking good so far, keep us all updated as how your getting on
182cup & 172 racecar
You could use a Saxo electronic pas pump like we have on our race car,works a treat,
I still maintain a good 230bhp endurance spec engine is what you want for this. It'll be bomb proof for circa 8K KMs, have excellent response, a good fuel burn rate and is achievable for sensible costs (built, dyno'd and in the car with loom and ECU for circa £7K). Essentially you're looking at a built bottom end with a sensible cylinder head spec, sensible cams, nice exhaust manifold and a good induction/filtration setup. More importantly all those bits are fairly off the shelf so you don't get into the massive cost issues that come with producing bespoke components for the engine package and even more importantly you aren't at the mercy of the lead times to produce more should you managed to break an engine.

I have used a different set up than the ones mentioned allready.
I have used a Volov 440 or 480 alternator bracket and tentioner, a 172 cup alternator. and then I have kept the 182 standard rack removed all the pipes filled the rack with PAS fluid to keep it loobed, blocked off the holes and then done this to two of the holes in the rack so the fluid can move when you turn the rack.
It does work and a few lads on here use the same stuff for their track cars and they say its fine if your moving. obviously its heavy if your stood still and trying to move the wheel.
I have tryed getting my 182 as light as possiable and i have a project thread. It might be of some use to you.

What sort of exhaust mani you refering to Matt? You thinking 421's with bigger lifters?
It might be worth getting the head CNC'd properly (i know a guy, but you'll be looking at £700+VAT) to get a bit more power and efficience out for the engine. Plus while it's all in bits you don't need to worry about taking it to bits

Stock 421 would be fine imo.
Do you mean uprated valve springs?
Nothing wrong with hand working a cylinder head. If I was having one done it would be via APD.

Probably not needed mate no, but i'm sure it will be hard. Forged bottom end, decent ECU, Cams, Map, Decent Exhaust (btb do 182 ones off the shelf now, best flowing system out there :approve: ). few more bits i'd imagine. basically send it to matt
Golf GTD Mk7
Yeah uprated springs Tom, but do the not require bigger lifters?
CNC would be better you can't argue with that surely? I'm sure hand work would make a difference, but it's going to be nowhere near as accurate.
Very good point.
I would reiterate what others have said about buying something already built, but you're past the point of no return now. I fear you may get to a point in the build though, where you really can't face another weekend in a garage on your back covered in grease with a build deadline looming, and turning the project over to company to complete. I've been there.
Equally, I fear you may end up with uncompetitive car at the end of your build. Again, I've been there, first time builds are deceptively hard to make competitive for the novice.
However, you seem to have a very positive attitude towards it, and I wish you the best of luck. Listen hard to advice sent your way, but take everything with a pinch of salt.

Ha ha yes I was there today
I agree with you on the deceptively hard part ha ha so MUCH to do, but im enjoying it.As for regs...
In Britcar regs it stated National B is needed which you get from one day of ARDS test don't you? Perhaps I'm mistaken here?
The Britcar Dunlop Production GTN Championship 2011 will operate to TWO classes - (as defined in section 32)
• Britcar Production GTN Class 1
• Britcar Production GTC Class 2
MSA Championship Permit no CHR2011/……..
MSA Race License UK Driver Grade Required
• Britcar Production GTN Class 1 National B
• Britcar Production GTC Class 2 National B
MSA Race License European Driver Grade Required
• Britcar Production GTN Class 1 National A equivalent (must have an EU flag on the license)
• Britcar Production GTC Class 2 National A equivalent (must have an EU flag on the license)
MSA Championship Grade D
Classes:
a) The name of the class will be “Britcar Production GTN”
Cars suitable for this class, subject to the power to weight ratio being acceptable, may include, but are not limited to:
GT4 / GT Cup / Super touring / 24hr Special / 996 Porsche Cup/ Ginetta G50
b) The name of the class will be “Britcar Production GTC”
Cars suitable for this class, subject to the power to weight ratio being acceptable, may include, but are not limited to:
Seat SuperCopa / Seat Leon Cupra / Renault Clio Cup / Honda Civic / Honda Integra
Best

One of our 4-1 manifolds works very well for this kind of application. Stock 4-1 or 4-2-1 are okay for tuned road engines/track cars making 220bhp'ish but having played with exhaust manifold design a lot on a couple of projects previously there is a fair whack of power to be found there!
We have access to a 5 Axis at the moment and are planning to add one to the machine shop before the year is out (even though it's a decent Gallardos worth of money!).
It would be port throttled, the throttle body setup comes under "induction/filtration". Our standard AT bodies are fine upto 250bhp, after that we have special build options available.
Mostly stock valve train is fine to 7800RPM which is all an engine in 230bhp spec would be turning, springs to our spec though as the cam profiles require it.
Regarding head work it doesn't make a difference how the metal is removed if it's removed in the wrong place which is what you tend to see on a lot of heads knocked out quick by tuner market box shifters. Also flow capacity on a flow bench doesn't tell the whole story, port velocities are massively important as is good cylinder scavenging to minimise residuals. We tend to use CNC with hand finishing in cost prohibitive places (head dependant) to make it easier to produce consistant port to port performance and build replacement heads quickly.... silly long lead times do not go down well in motorsport!
No I meant the dashboard not the dash unit
The black GRP dash section the X85 runs? It's LHD for a start and attaches to the roll cage in the X85. It's also really expensive for what it is (circa 450 quid if memory serves).
If you want one doing our carbon shop can knock you something up in GRP for not too much more and it'd be RHD as well

You get a National B by doing a one day ARDS test, and completing (nb: not starting) six races to the satisfaction of the clerk of the course whereby you can remove your novice cross. I don't think you're allowed to do the 24hr as a Novice. Best to call up and check. One of those six races can be substituted by spending a day as a marshal.
Golf GTD Mk7
Ta. Thought it might be
they have a nice setup at CNC heads in Stockport. Made me laugh it was all upstairs. Felt sorry for whoever had to install that. Amazing to watch in action :approve:It's fine we've got drivers with a couple of sigs into Britcar 24hr, it did involve us having a chat with Tucker and co to sort it with a personal nod they weren't complete f**k wits but no major issue.

Interesting on the mani! Cost
Depends on the material, circa £1K in something none exotic. Only required for 230+bhp though.
