Cheers, do they have a Hub Dyno then?

 

I am thinking I will probably want to use a Hub Dyno from now on as since I have been looking for places that have Hub dynos I have read horror stories of people using Rolling type Dyno's and them destroying R888's very quickly... not what you want when each tyre costs £250!!

 

We tried once on a rolling road with my car, it couldn't get traction and killed the tyres so the hub dyno at Abbey Motorsport in Surrey is where I go for mapping with Ryan. They're great down there, surprised Ryan didn't suggest them himself.

I can see why you want a hub dyno, add two tyres to the cost of a mapping session and it gets a bit expensive.

I believe Austecs isn't hub. I still have the magazine feature of this car, love it, I really do.

Exactly, there is also the issue that my car wont get on roller Dyno because of the flat floor.

Ah which feature the original (Banzai) or the most recent one (Jap Performance)?

Sweet!

[ManwithSupra]

I know we are not supposed to copy the same post into multiple threads but I wanted to add this to my project thread so hopefully I can be excused on this occasion.

 

Here is a quick post track day rundown from my track day at Goodwood yesterday.

 

First impressions of the track, wonderful!

Lovely track, good facilities & great marshals.

 

The track is so smooth and quick so much better than Combe!

I really managed to push the car hard this time (mainly as it was dry and hot) I really would recommend this track to anyone.

The only downside is that there is pretty much no runoff, that means it would be a scary track in the wet, but if its dry its immense!!

 

Here are some Pics of the day..

 

 

 

 

 

 

 

 

 

Here are some Flybys of the car down the pit straight..

 

 

 

 

I have some in car footage which is uploading right now, it was a shame we were not allowed to have external camera's but still I am glad I managed to get some video footage.

Looks fantastic, how were the Nitrons?

[Rob_Mitchell]

Nice! looks like you had a great day Richard. Such a distinctive sound!! can always tell a supra

[Wez]

Very nice matey, flying the MKIV flag

[ManwithSupra]

Immense mate, just incredible they are a million times better then what was on there before.

I can power down a lot earlier coming out of the bends with no oversteer the stability at speed and through corners is just amazing, riding kerbs no longer throws the car off balance, It’s just transformed the car on track, inspires so much more confidence, Braking also seems better too!

[Dan_Q]

oops- ignore my questions in the other thread- goodwood, much better than the old ones, nice one glad to hear it

[Willson]

Awesome!

[Mike2JZ]

Can't wait to see the in-car footage, been waiting since you posted on fb yesterday

[ManwithSupra]

In Car as promised

 

 

2nd part of the first video

 

 

I will upload the other ones later tonight.

Money well spent there then, like most things in this world, you get what you pay for.

[Dan_Q]

just watched the vids- great stuff! looks like a lovely clean venue. Not many cars out there either, not much traffic- great

 

what was the cost like compared to other circuits, if you don't mind me asking?

[ManwithSupra]

Agreed mate, they still need a bit of setting up but we are getting there

Yeah the circuit has been kept in great condition along with its facilities.

No not many cars, they run a maximum of 25 cars a day out in packs of 5-7 cars per session (depending on noise levels) each car is separated by 10 seconds and each session lasts around 15 mins. They run a first come first served basis in the pit lane but we found that at any one time around half of the cars were not running due to people checking their cars, getting drinks, food etc so the maximum waiting time turned out to be no more than 15mins between track sessions.

 

Its quite an expensive track as a full day comes in at £320 and a half day is £165 but to be honest with so little cars running you have so much more room on the track to enjoy as well as getting a descent time out driving. Its never going to be as good value as an Open pit lane day like they operate at other tracks, but for the proximity of the track to myself, the quality of the venue, the number of cars running and the facilities I am happy to say its my track of choice now.

 

I didn't go for the full day, I went for the half day afternoon session but ended up getting more time out on track then I did at an all day track day at Silverstone so well worth it IMO.

Hi all,

 

A Little update on the car

 

After every track day I do a major strip down on the car to make sure there are no seal failures, leaks, damage etc.

 

The Goodwood Post track day strip down had shown up a couple of small issues (nothing too serious) one was that I found a small anmount of coolant on the floor when I raised the car up on the ramps. On inspection I could not find a leak anywhere on the car and the coolant level was good, even when the car had been run up to temperture there was nothing so the only thing I could think of is the pressure cap on the rad had let some pressure off. The biggest issue was that I had a small Transmission oil leak on my V160 Gearbox. It looked as if it was coming from the selector input shaft (which is a common problem) or it may have been coming from the Main Output shaft but it’s difficult to tell (as if the selector seal leaks it leaks over the output shaft).

 

I decided to purchase both seals but first I set about looking at the Selector shaft as this one is the most common problem and the easiest to do. As you can see it was pretty wet up there so I am guessing this was the culprit.

 

I used the following how to on replacing the seal but as my transmission tunnel is so much larger than a normal Supras it was easy to do this without removing the Propshaft

 

And installed some temperature strips to get an idea on how hot the brakes are getting.

 

For people who don’t know why I am doing this, here is a brief explanation, popping a temp strip on the calipers is to help with an Indication of how hot the brake fluid is and therefore making sure that it is in its operational range. It also helps in making sure I am not destroying the seals on the master cylinders and brake pistons... If it is too hot then it will tell me that I need to look at changing them after "x" amount of track sessions or after every track session etc.

 

Hopefully I will be heading out on track on Monday (at goodwood again) if the replacement selector seal was the issue, Otherwise it will be the main ouput shaft seal and I may not have time to get it all done before Monday.

 

Anyway just a quick update.

The master cylinder seals are 100% safe even if you melt the calipers with a welding torch, the fluid does not circulate. (Slight caveat, Touring Cars went through a brief flirtation with self circulating fluid in the calipers, but it didn't last and was very specialised). You are better using temp paint (AP and others sell it) on the discs, as most caliper fluid temp rise is directly through the pistons, and the discs themselves will give a good guide. Castrol SRF fluid will give you 100% peace of mind. That's what i use, it is readily available and just the job for your application. If you need more seals I have some on special offer in this thread:

You are really getting into this lark now!

Thanks chris, thats useful to know. I was looking at the temp paint that AP do but was put off by the price so thought I would give these a go. If its a better way of monitoring then I will use the paint instead

 

Cheers for the link for your special offer (bookmarked)

 

Yeah getting well into it now I find it really interesting and really enjoyable and thats not just getting out on track but all the work that goes in setting the car up etc, its a lot of work but when you can feel the difference its really worth it

[Dan_Q]

brilliant stuff, great interesting read keep it up

[Chris Wilson]

Disc temp paint is better, really. You can of course do both. Castrol SRP will put fluid boil worries behind you altogether though, then it's just the pads and discs to worry about! Not sure what pads you are running, but until you try Performance Friction's range of compounds you won't know how a good pad can change things! Sadly, they ain't cheap, but you must be getting the idea racing is not a cheap hobby by now I am finding it harder to get the enthusiasm up for all the prep, after track service, and the loading and unloading as i get older. Plus I find it harder to justify the rising fuel costs, and tyre costs. tyre prices have gone through the bloody roof. I am to be found on the amateur radio workbench or on the radio itself more than on the track at the moment.

Cool, I have ordered the Disc temp paint and will use both together (may as well keep them now I have them)

I will have a look at SRP fluid as well.

 

Yeah it’s getting more and more expensive with the rising cost of tyres and fuel and there is less and less time available these days also it seems. I do know what you mean about the effort expended with loading cars, servicing etc. etc. it would be a nightmare if you were doing it on your own, Luckily a couple of close mates are pretty enthusiastic about track days, racing and always lend a hand which splits the workload up a bit which makes it a bit more manageable.
