ManwithSupra Posted November 12, 2014 Author Share Posted November 12, 2014 Carbon passenger seat arrived yesterday.

pedrosixfour Posted November 13, 2014 Share Posted November 13, 2014 Rich, word of advice mate. Before you rock up to your first Time Attack round next year find out if your seat position is acceptable when viewed in relation to the main roll hoop of your cage. I may be wrong about this but I have a feeling that no part of the driver's seat should be behind any part of the main roll hoop or uprights and a scrutineer might call you up on it. I'm only drawing your attention to it now as there'd be sweet feck all you could do about it on the day and IF modification is needed to comply with whatever rules the UK T/A adhere to at least you'll have plenty of time to do it right before the first round.

Cheers mate you are eagle eyed I had already spoken with the TA officials who brought potential issues of cage up already and according to the MSA blue book I am going to need to make some changes to the cage anyway to make it compliant. So I had to get the seat position first in order to get the measurements for the rework of the cage. Passenger side will be going in this weekend so the cage will be reworked and some more triangulation added as well. This is why none of the carbon replacement panels have gone in yet, no point in cutting the new panels to suit a cage which at least 60%+ will be changed anyway if not entirely. Gonna feel odd about chopping the roof off to do the cage lol.. kind of car craniotomy hahaha Edited November 13, 2014 by ManwithSupra (see edit history) Quote Link to comment Share on other sites More sharing options...
ManwithSupra Posted December 3, 2014 Author Share Posted December 3, 2014 I have just finalized the ratio's on the new seq box From working out speed vs gears on my V160 etc I have worked out I have an Auto NA diff crown (4.083:1) on my TRD Diff. I just need to go about changing the Diff crown from a Auto NA to that of an Jspec TT Manual (3.266:1) Is it as simple as removing the diff, taking the diff out and changing the crown or will I need to change the pinion on the diff input shaft? Obviously things like seals, crush washers etc will all need to be done at the same time. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 3, 2014 Share Posted December 3, 2014 The crown wheel has to mate with the pinion for the same ratio pair, and not only that, they are made as matched pairs, so realistically you need a different ratio differential assembly to cannibalise. God knows how much a new CWP is from Toyota, assuming they are even still available. It's a pity the Tracktive won't handle the torque, they have a pair of relatively cheap drop gears at the back of the box, 20 minutes to change them. This is effectively like having umpteen diff ratios available that can be swapped in less than half an hour. Quote Link to comment Share on other sites More sharing options...

I will have to keep an eye out for a Jspec TT Manual Diff and then change the whole thing over to the TRD. I know what you mean Chris, its a shame.. the Tractive box ticks all boxes apart from the power one. Would be ideal to be able to change ratio's like that, especially for different circuits etc. I will see if Toyota still sell them, I kinda doubt it but would be good to know. Found the part number for the Crown and Pin kit - 41201-19645 (includes ring gear/ pinion gear/ nut / bolts/ crush sleeve/ pinion seal) Now just to find where someone can get hold of it..so far seems pretty expensive.

Chris Wilson Posted December 3, 2014 Share Posted December 3, 2014 Yes, gearboxes with drop gears make diff ratios pretty irrelevant, and changing ratios cheap and ultra quick. I think Toyota stopped selling crown wheel and pinion sets a while back, but you may finf new old stock somewhere. Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted December 4, 2014 Share Posted December 4, 2014 I recall enquiring about a new 4.273 CWP from Japan through a company called Titan Autoworks a few years back, as far as I can remember the cost was about €700 delivered. I think he's something like the Irish equivalent of Nic, when he was based in Hong Kong, so the guy mightn't even be trading anymore.

ManwithSupra Posted December 4, 2014 Author Share Posted December 4, 2014 So I got a couple of leads, Good old Steve Manley can get one for me in 7 days for £880.48 I have spoken to Jesse Streeter (lots of people in Aus use him to import parts) and he can get it from Toyota in Japan for ¥43308 which works out to be around £230... much much better :d. All I have to add is Air Freight and then customs charges on top which should not be a massive amount (well not another £600). Will make the decision based on what the Air Freight and customs charges are. It would be good to get new CWP kit rather then butcher another diff which has millage on it. Chris as you are a legend and well I don't want to mess it up, what would you charge to change over the crown and pinion and rebuild this for me?

Chris Wilson Posted December 4, 2014 Share Posted December 4, 2014 £175 plus any parts needed. Seems a great price on a new CWP, very surprised by that, why not try and get a group buy? Quote Link to comment Share on other sites More sharing options...

Perfect, That would be great, I will let you know when its good to go That's a good idea, I'll see if he can do any better on price If I was to purchase a number of different CWP kits. I will ask the mods if I can start a thread for interest on it and perhaps move forward with a Group buy. Quote Link to comment Share on other sites More sharing options...

Ha cheers mate, Its currently being stripped back even more, the cage is now being reworked and upgraded due to the new seat position and regs. When thats done lots... and I mean lots of Carbon panels going in to replace the aluminum ones. Quote Link to comment Share on other sites More sharing options...

That part number isn't listed for the Supra but they may well share the same diff as the ratios are the same. Quote Link to comment Share on other sites More sharing options...

Works out to be around £450 Once shipping, vat and the various import taxes have been added, which is still half the price of getting it new here but I wonder if I can get a 2nd hand diff for less than that here in the UK?? Hmmmm. Quote Link to comment Share on other sites More sharing options...
ManwithSupra Posted December 6, 2014 Author Share Posted December 6, 2014 New HANS device arrived today. This one fits nicely. Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted December 6, 2014 Share Posted December 6, 2014 New HANS device arrived today. These mandatory in UK T/A now mate? They seem to be a useful bit of kit and even if they're not a compulsory item there's very little reason not to have one, especially now that there are several versions available. Some even come without the eye-watering price tag! I'll be attempting a helmet upgrade again in the new year, if so it'll be an FHR compatible lid with the intention of getting a device like this. BTW, what helmet are you using? I've been asking regular track users what helmet they'd recommend for noise suppression and, like most things, ask twenty people get twenty different answers!

Hi Mate, No not mandatory, but for the money its well worth the extra safety, and the fact they start around £280 its well worth it. I for one do not want a Basial skull fracture if I do come off the track and hit a wall hard. This is a good example of why you should have a HANS device (if you want to skip right to the incident go to 1min 40) I have two helmets a RRS open face and a Stilo full face. In terms of noise, I am not really that great to take advice from as I am pretty much stone deaf in one ear lol so the sound levels have never really caused me much discomfort. Although I would say the Stilo helmet is probably better at noise suppression.

pedrosixfour Posted December 7, 2014 Share Posted December 7, 2014 I've seen that clip before on another forum, there was even a bit of a debate on whether the guy in the Clio was at fault for causing the accident! I think I'll be trying an RSS full face helmet myself, I've heard good things about them from other users. The real trouble is not all manufacturers make a lid to fit my dome so options are fairly limited at my end of the market. Quote Link to comment Share on other sites More sharing options...

ManwithSupra Posted December 8, 2014 Author Share Posted December 8, 2014 I am also thinking of adding the Geartronics Easyshift ECU with the 69G box to aid with reducing dog wear on flat shifts Unless the Syvecs ECU can do this based on a closed loop. http://www.geartronics.co.uk/flatshift.htm Quote Link to comment Share on other sites More sharing options...
