Are you running a bias valve with yours? Mine will still have the standard 1.6 rears when they're fitted. A mate suggested gutting the standard bias valve so you get a 50/50 split front to rear.

Urrrgh, bloody old cars. I was supposed to be going to the MX5 National Meet tomorrow and be on the Moss Europe stand. No chance now. Stripped the old Throttle Body off and as suspected one broken throttle spindle.

The replacement arrived yesterday but as is often the way with used parts it's been stripped of pretty much everything.

I went to swap over the various bits and rounded off 4 bloody screws. I don't have the time to drill them out or find replacements before tomorrow. Rather than take the MK2 instead I'm going to soldier on with this and get as far as I can.

Sometimes I really hate my hobby.

Great thread Horney and I've enjoyed watching the videos, the car looks like a lot of fun!

Are you involved in any series with the car at the moment? I can see you've taken part in some sprints but is there a league table or anything like that? (Apologies if I've missed something!)

smile
Not with this car, just the occasional Sprint/Hillclimb, AutoSolos and Tackdays. I have a 50% share in a Max5 race car myself and a friend will be racing next year and I also have a stake in MK2 Turbo Endurance racer we're taking to the Race of Remembrance in November. I think I have an addiction, lol.

Update time.

Managed to find the time (i.e took a day off work!) and headed down to Skuzzle Motorsport in Winchester to steal one of his lifts for the day and fit my WIlwoods.

As probably mentioned earlier in the thread I realised after I ordered these they wouldn't fit behind my beloved Compomotive MLs. For the time being the car is running on some Team Dynamic Pro Race 1.2s I swiped off our Max5 racer.

I've ordered some of the same wheel but in Gold which I'm waiting to arrive.

Today there was an organised run out to a pub and for lunch and then to Goodwood via some nice roads which seemed like the perfect opportunity to bed the brakes in.

Next up Farnborough and District Motor Club's Sprint Royale on Sunday. Looking at the others in my class I've got my work cut out!

Looks good. Sorry if I've missed it, but what wheels are those (and what size)? - they suit it smile

I have an unhealthy addiction to stickers and decided some Spec Miata inspired MAZDA stickers were in order.

Loving your car mate! And that opposite lock video! biggrin

You cannot beat an MX5 on track for value and fun factor! I did the ring and Spa in my old turbo last year. I still miss that car on occasion! I will definitely return at some time! My turbo one was a MK2.

Good luck with all your ARDS stuff as well! Proper racing.... now that sounds like real fun. Was the ARDS expensive?

Edited by adz9 on Tuesday 29th September 13:15
I try to blot most of the expense of motorsport out of my mind for fear of driving myself insane. I think it was £350 ish for the test at Goodwood and the medical was £80 or there about through an online booking company as my Dr wanted £150!!!

Yesterday was race day! I took the Mazda to the Farnborough and District Motor Club Sprint Royale. Running in class 5 for road going cars over 2000cc (the supercharger makes it 1600cc x 1.6 = 2560cc for equalization) was going to be tough. In my class were 7 runners including a supercharged Mustang GT, an MG SV and an S14 200SX. My main target of the day was a Mini Cooper S JCW as we're both 1.6 Supercharged and similar power to weight as he has a bit more power than me.

Arrived and ready for scrutineering:

In the queue for the first practice run:

Another queue shot:

The Mustang retired with a broken gearbox and I managed to beat the mini and bagged 2nd in class and 25th overall out of 80+ entries. I even beat a Metro 6R4!!!!!!

Here's a vid of the 2 practice runs and 4 timed runs:

Such a great day and already looking forward to the first sprint of 2016.

Shame you couldn't make it as the weather was perfect for spectating.

National B (Non Race) for Sprinting which is just a form filling exercise and sending off a photo. You also need an FIA approved Race Suit, Gloves and Helmet and in some classes from 2016 a HANs device.

Well done! smile

Some good driving there bud. How far were you off the leader? What mods do you think you need to do to improve the car?

0.73 seconds. Best improvement will be seat time but, you know, more power can never harm your chances right? ha ha. I think for next year some proper sprint spec tyres in a super soft compound will be purchased. Power wise there's not really any quick wins there anymore, next up is vernier cam gears and removing the overlap to see if that brings any gains.

Sorry if you've mentioned this. Have you swapped out your yellow injectors?
Also, what's the weight of the flywheel you put in, ~4kg?
Cheers

Nope, still on the RX8 yellows and got a bit of headroom left in them yet.

The flywheel is a CC Ultalight which is just under 5kgs.

It's running 220-230bhp at the flywheel. Not loads but enough. It brakes traction enough plenty already but any extra power will help propel it down the straight bits fast plus with more grippy tyres I should be able to use more of the power on exits. 250 at the flywheel with some soft avon will probably be enough to keep me in with a chance of silverware in this class.

I've been doing trackways for about 10 years and had a couple of sessions with Dave De Costa at Castle Combe but no proper race tuition. I did my ARDS earlier in the year and will be competing in the Race of Remembrance at Anglesey in a few week time. For that I'll be sharing a 300bhp turbo's MK2 MX5 with aero. My first ever circuit race, 45 cars on track, some of it at night and it's being covered live on Motors TV. What could possibly go wrong? biggrin

A cracking pic from Sunday’s sprint.

Untitled by Nicholas Horne, on Flickr

Having ended the season in this car on a real high with the 2nd in class trophy it’s time to focus my attention on 2016. Winter is a time for plans, upgrades, improvements and repairs. The next 5 weeks will be consumed by the Race Of Remembrance prep and competing there in Skuzzle’s MK2 Aero Monster but after that attention will be back on this wee beasty.

For 2016 my aim is to compete in all three Farnborough and District Motor Club Sprints (Dimanche, Abingdon CAR-nival and Royale) as well as at least one competitive round at Gurston Down Hillclimb. This time I’m wanting some top step action in the class as well. With that in mind I have the following list to work through before April. It’s a tall order budget wise when factoring in I also want to run the MAX5 racer in a couple of rounds of the MAX5 championship.

• Rust repairs to the sills (Rust really isn’t lighter than carbon fibre).
• Repair/replace cracked peddle box.
• Some more sprint/hill suitable rubber with more grip from cold.
• Get the car set up and corner weighted.
• Adjustable cam pulleys for a bit more power.
• 2.5 Sport rear brakes.
• Finish plumbing the extinguisher in and battery cut off pulls (it won’t make me faster but BecauseRaceCar).
• Purchase and fit some proper 5 point 3” harnesses.
• Adjust the seat to lean back a bit more.
• Fit passenger bucket seat (lighter than standard seat and I need to run both seats in my class as per the regs).
• Steering wheel hub spacer to improve the driving position.
• Fab up and fit some door bars to the Cusco/Safet21 4 point cage for a bit more chassis rigidity.

There’s probably some more stuff to add to that list that I have forgotten.

My new wheels arrived a couple of weeks ago and I finally got around to getting the tyres swapped over and the wheels fired today.

Off with the old:

On with the new:

Exactly the same, just a different colour. The white ones will be returned to their proper home on the Max5 race car.

I've also picked up some vernier cam pulleys:

The plan with these is to get some custom ground cams from Kent and with these bolted to them see how much more power we can get out of the old girl. Currently at 190bhp-ish at the wheels and hoping to get her over 200bhp at the wheels. This will be a winter project along with a lot of other things that need doing ahead of the 2016 Sprint season.

Before all that kicks off there's the small matter of The Race of Remembrance 1000KM endurance race at Anglesey in this weapon:

Tune in to MotorsTV over the weekend of 7th and 8th of November to watch it spitting 3 foot flames live on TV. The start of the race is Saturday night 4pm - 7pm and the remainder 10am through to 4pm on the Sunday, I believe the coverage is non stop.

Extinguisher and cut-out pulls on the OS rollbar hoop? Id be interested to see how you mount them.
I don't have any pulls fitted yet, it's on the list of winter jobs. smile
