Now entered. Had the confirmation email but the entry list doesn't want to open on my phone. Any chance someone could check it for me to see if team Madsprout has made it onto the main entry or maybe the reserve list? 

Thanks

It looks like @Andyone is the group organiser, but not sure he’s around here lately. Maybe @TimW can help. 

Hi  @Colin Caygill   and welcome to the the club. I have heard from the Cheshire local group organiser that the teeside meet is no longer being held (I believe it became somewhat political). If you would like to take on the role of local group organiser for the region then I'd gladly chat with you to see how the club can offer its support.

Thanks for clearing that up guys. So the GT clutch will be ok with the saloon gearbox then. I guess I'll just have to try it and see if it's man enough to take the power. It's all somewhat irrelevant now as I've had to withdraw from this years RBRR. My transplanted kidney has decided its not very happy so not sure what's going to happen in the coming weeks.

You could try reading through these extremely comprehensive notes

https://www.buckeyetriumphs.org/gearbox

I found an oblique comment suggesting springs differ between models on page of part 1 but not detail.

Suggest the easiest method of getting a definitive answer is to ring Overdrive Services (other the other one whose name temporarily escapes me…..)

Thanks for that Nick.

TR input shaft is bigger, so no use with a saloon box

Isn't that only on the later TR's Clive? I'm sure I've read the TR4, 5 and early TR6 are the same as a saloon input shaft therefore the same as a GT6?

I'm told they have a shorter life in a TR6 (or 2.5PI) than a GT6, which isn't surprising. I certainly had one wear out on my PI. But then my GT6 hasn't had its clutch changed since I replaced the gearbox in 1993, before its first RBRR.

That's strange because in theory they are the same players as all the saloons. I have found a genuine Laycock friction plate that's listed as a TR4,5 and early TR6 then a separate listing for the same item suitable for 2.0L, 2.5L saloon, GT6 and Vitesse. I've not idea if the 2.5pi and the TR's used the same friction plate but with a different compound of friction material...this is becoming an interesting project.

The same friction plate was used in the TR6 so capable of handling the 150bhp of some models and possibly capable of a bit more depending on usage. Otherwise I believe there are uprated ones available...

Good point. Thanks

So....Next question 

Do we think a standard, genuine borg and beck friction plate (made in the UK) will take 180bhp and 200ftlb of torque? I'll be using a saab 99 pressure plate and saloon gearbox.

Ok Thanks Nick

My information came from a TR forum so hardly a reliable source.

I though that spring thing applied to A-type rather than J-type? Could be both….

Nick

It was Just based on some research I've been doing on the TR forums Nick. If it only applies to A-type then I need not worry I guess

I've read that the TR6 has 8 clutch springs in the overdrive but the 2.0L saloon only had 4 springs. The 2.5pi had 8 springs. I've got a j-type saloon box to put in the GT6. Is there any way of telling if I have a 4 or 8 spring J-type overdrive without pulling it apart?

I was going to say, don't use a saloon flywheel!

But you beat me to it. 🙂

it is approaching 60 in second, then add OD on second (easily done on a later saloon box) and you are up round 70.

 

Great stuff. Do I need to change the backplate from a GT6 one to a saloon or TR6 one?

I think it may be off a dolly, possibly 1850? Mine used the std saloon carrier, made the clutch very heavy, plus I had to modify the cross shaft. 

Mike Papworth will know.

It is down to the saloon flywheel being much thicker. Messes the geometry up.

Thanks Clive

A call to Mike Papworth or Tony Lindley-dean is in order I think. I really need to keep my balanced GT6 flywheel

Sprint, as in dolomite sprint, gears are totally different to gt6, and won't fit into a gt6 case.  Maybe there are gears etc about with "sprint", ie racing, ratios. Probably from sah etc.

Yes, dolly sprint gears can be used in a saloon box. But watch out, I think tooth angles changed at some point. Possibly when they changed from a to j type? But do check that.

 

In my vitesse I broke several 3.27 diffs,  usually pulling away "promptly" in first. It put a massive strain in the diff, a longer first would have been a great help. 

Thanks Clive 

I'd have thought that a shorter first would put less torque through the diff as it would be easier to spin the wheels so not being as hard on the diff?? I've only broken one 3.27 and that were the roll pins in the carrier that broke. I don't have that issue now with the LSD. 

Think I've made the decision to fit the saloon box as is.  I've now sourced a dolly sprint cross shaft and slave cylinder bracket. The only thing I need info on now is what clutch release bearing carrier to use with the gt6 flywheel and pressure plate??

My brother had a modified GT6 that had a TR6 28% j-type and that apparently had a sprint gearset?

I agree and as I have the 3.27 diff I think itll be ok. Any idea how fast you can get out of it in 2nd? I've checked the saloon ratios 2nd is quite a bit shorter than 2nd in the type 9 box. The type 9 is 1.81:1 but the saloon is 2.10:1.. not a huge difference granted but I do find 2nd a bit short with the type 9 

Can I swap and change ratios using a Sprint gearset? I have a lead on a couple of sprint boxes going cheap so thought it may be worth a try as folk fit sprint ratios into GT6 cases and as the sprint box is very similar to a saloon case I was wondering if it was possible?

Genuinely guys I'm not concerned about the short first gear. It's not as short as the type 9 and I have a 3.27 fitted so 1st will be an improvement on my current setup. There's no such thing as a cheap triumph gearbox of any description these days!!

A 3.27 diff will help a lot if you havent already got one...

Already have a 3.27 LSD fitted.

Do look at the ratios, especially first, of any substitute box you might want to install....

I have already done so. First is significantly shorter than a standard GT6 box but it's also considerably longer than the type9 I currently have. 

Anyone know what mods I need to do, other than chassis, to get a saloon box to work in a GT6?

Are you attending?

I hadn't intended on it but if your stuck for RBRR cars then I probably could 

As said above if it doesn't smell hot, doesn't chuck out any coolant and doesn't boil then there's little to worry about especially if your digital thermostat isn't reading above about 110deg

Hi Clive

I've now done 2 RBRR's and doing the 3rd this year. As I'm only 30 minutes from malvern your welcome to have the GT6 for the weekend. I can even put the rally plates on it .

We’re 100% sure now that any images from the pre-2013 website - that hadn’t already been imported to the previous version by Keith - aren’t in any backups we have so can’t be imported now. 

There’s a very small chance that a backup will be found with them in, and people are looking. I’m sorry about this @TimW and others who’ve lost content.

Trying to find a silver-lining… this shouldn’t be a problem in the future, as the site uses a better supported and straightforward storage method now. 

It is what it is Ben..not a lot that can be done about it if they aren't there...

Thanks Ben

It's such a shame the pics have been lost. My car is mallard blue and the reg BWP793M if its of any help. Thanks for at least managing to find it. Brings back some great memories
