Awesome 

The weathers coming back now so I'll pop and see you soon for a spin 

 

Yes, some fresh Millers oil is on its way and I’ll be taxing it this month so definitely have to organise meeting up. 

 

@davey_83 I’m sure will be getting something in the diary soon too!?

Great work mate :)

Congrats on the new addition to the family :)

 

You ever go over to Bedford autodrome? The full circuit is fun, We hope to get a few days out there this season may be see you out there??

 

Haha yes, it’s a shame to hide all this stuff away never to see the light of day again!

 

Cheers!

Thank you, she’s great but not feeling such a new addition now at 4months old already!! Where did that go!! In fact the whole of 2018 seems to have passed me by. 

 

I’d never make the noise limits there sadly, I have driven it and it’s good fun although very flat which is a shame. With the way it’s all going I’ll have to have an exhaust made fairly soon to be able to to keep using it on track! Luckily the ‘Ring has a 135dB limit so that one should be OK for a while!!

Finally got the car out the garage and down to the MOT station for another years ticket!

 

Changed out a couple of rose joints that had just started to have a bit of play in and dropped in some of Millers finest engine oil which new K&N filter and all good to go again.

 

Got a busy couple of weeks with the car as next Saturday its getting a detail clean from resident car cleaning obsessive @davey_83, Sunday a track day at Silverstone and then the following weekend is the Midlands meet which has really good numbers attending so should be good.

 

A couple of pics of me and my Brothers cars all ready for 2019

Its an angry little go kart!

 

Ahhh sorry mate, I meant it’s 300hp now. I’ve edited the post to make better sense.

 

Stock Vx220 turbo is 200hp the Vxr’s came with a different turbo and a map tweak to 220hp from factory.

When you gonna start with building the engine? :P 

 

The block's still at the machine shop but I'll be collecting that soon!

 

There's still a few bits on the shopping list that are required to get the build under way.........but I'll definitely be posting up progress when it begins!

On Sunday I headed off to Silverstone where I met up with @RobPhoboS and had a great day out on the International Circuit!

 

Both Z's ran really well from first to last sessions...........great way to kick off 2019 track days! I did make a bit of a error though and didn't realise/forgot my front pads were about 2\3rds done and down on their ass so had to nurse them a little throughout which was a shame but still enjoyed the day and great to be out driving the car properly again!

 

Didn't actually take too much footage but here's a few clearer laps from the day

Really great day, not just for the track day but to finally catch up in person !

Your car is excellent, lovely sound to it and it really goes, I'm going to be even more jealous after your next round of spannering :clap:

 

My first track day in quite some time, apexes seemed several meters away for me :lol:

Looking forward to the next one, and I'm praying my tyres arrive this week :scare:

Agreed! and yeah good to put a face to the name...............in fact you met half the family!

 

Cheers, appreciate the comments! Yeah new engine will be a while coming but will be worth the wait.....not really necessary for the road but great for track work......will hold those 3rd gear slides for a bit longer eh!! 

Your car also has a really nicely set up chassis and the improvements over the stock DE with the cams etc were great for track work! Credit to you and all the work you've put in to it...........makes the late nights in the garage and no skin on your knuckles all worth it!

 

Yeah me too.......think we both took a couple of sessions to blow off the cobwebs but there wasn't much wrong with the pace after that.......still not sure I took Stowe corner the same way twice all day!!

Hope the tyres do turn up........you need em!

Just read through this thread again, absolutely incredible. So much respect for the amount of work put into this, I've got to have a ride along some day! 

 

Thank you!!

 

I have to remind myself sometimes how far the car has come and how much work has gone into it.................and continues to do so!

Not much of an update as opposed to some maintenance required! Rather ashamedly the car went off to Silverstone with the pads in far worse condition than I'd usually allow but I'd not realised they were so worn after its last use so had to nurse them on track but still good enough to have a good time.......to add insult and more cost the tyres all round were looking equally as sad!

 

So with the 'Ring up next (sadly forecast is looking very poor!) I needed to get some new pads on it along with a new set of boots! Also diff oil was replaced and a quick brake bleed with PFC665 fluid just to get it all back to top fitness

 

New pads, all installed..................as you can see were very much required!!

Then for team boss and head mechanic to help on the pedal while I bled the brakes

And then finally sorted tyres......wont bore you with the whole tail but was going for a set of AD08R's again as they're great but Demon Tweeks let me down/stitched me up a treat!!..........quick call to Yokohama and luckily on the shelf was a set of AO52's with my name on in 255/40 and 265/40 so me trying these great tyres one day was fast tracked somewhat to right now! Looking forward to trying these out..........especially as my spring rates were actually chosen for this level of tyre. Lets just hope its dry enough to see what they've got..........that said they're meant to be a step up for wet use also.

Re engine build.......its all collected and looking good. To be honest I think juggling using the car and doing all the work required at the standard I'd like to do it to is going to require me taking it off the road at the end of the year..........got some weight loss planned for it too while its out of use so think it all makes sense to do it that way.

If anyone is up for the task of a shakedown on unknown tyres if Martin :boxing:

Dry setup what tyres pressures are recommended for RWD? 

 

Good move on the pads too, Silverstones BIG stops saw them off.

Let me know how the tyres get on. If they perform from the off and are great in dry and wet they could be my next hillclimb tyre as they are on the 1b list. 

They get great reviews but supposedly start to go off after a few hard laps which won’t be an issue for me. 

@davey_83 with pressures i have found starting with the manufacturers recommended for the weight of the car is a great start and tweek slightly from there.

Haha thanks for the vote of confidence mate!!

 

The AD08's sweet spot was 34psi hot so I'm gonna start there and see how I go, I've also got a new infrared thermometer to take with me so I can see how they're getting on.

 

Anglesey last year finished them....Silverstone then killed them!!

I'm expecting them to be very good indeed. I've used the AO48 in the past and they are the best tyres I've ever used and these are the  successor to them developed from their tarmac rally tyre the A051T.

I'd be surprised if they went "off" quickly, I've always found Yokohamas to take a lot of abuse and stay very stable over a good length track session. Most times I hear people talk about tyres going "off" is when they've not set tyre pressures as they get hotter and end up running at 40psi and so only on half the foot print and wondering why grip drastically drops off.

 

I'll obviously let you know how I get on but I suspect you'll be ordering a set!......worth noting they come up large on the sizes and also look at the wheel widths for tyre size they recommend. I'm on the minimum of what they allow and 1.5" off the front and 1" off at the rear what they recommend as best which was a bit of a surprise!

Hard to find decent tyre comparison vids as most people telling folk how good tyres are on YouTube don't actually seem that good at driving!! This very Japanese vid shows a handy Jap wheel man in a RX-7 at Suzuka with the AD08R vs AO52 (with the same 255/265 widths I'm using).........lap times 2:29.8 to 2:24.98 so its a very quick tyre! Looks like the attitude in car is quite similar just at a higher grip level.........win win!

Good info, seems strange how the recommended wheel width is the widest size in the “acceptable” range. Maybe the tread block works better with a bit of “stretch”?

the sizes on offer are better for me with the 40 profile, it will raise the car back up little as it sits too low at the minute for normal use. 

To be fair, they are gonna be better than the AD08R as they are more a high performance road tyre than out and out track tyre. 

Looking forward to the review though as the nankang AR-1 i have are not at their best when cold or damp, the extreme wets are useless in the dry or warmth. In this country where we have 4 seasons in one day, these bad boys could be ideal, fingers crossed.
