Guest Posted January 23, 2018 Report Share Posted January 23, 2018 Hello. Before I start searching & phoning, does anybody know if the rubber sealing strip that runs along the edges of the Vitesse g/box tunnel is available, please ?? Additionally, what have other owners done to insulate / noise reduce the g/box side of the tunnel ?? I was looking along the lines of this: https://www.ebay.co.uk/itm/RATTLEMATT-x-20-SHEETS-Car-Audio-Sound-Deadening-Proofing-Sheets-Pads-Panels/300894542405?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055119.m1438.l2649 Many thanks.

Guest Posted January 23, 2018 Report Share Posted January 23, 2018 My first question appears to be a yes, having found the following: http://www.angclassiccarparts.co.uk/home/triumph-5981/vitesse/body-parts-fittings/gearbox-tunnel-cover-fitting-kit-vitesse Obviously out there, now to find who supplies at the best price. Kits are available for the Herald, Vitesse, GT6 and Spitfire. Regards. Richard. Link to comment Share on other sites More sharing options...
mishmosh Posted January 23, 2018 Report Share Posted January 23, 2018 The club shop sells it. Also try Dynamat for sound proofing. Link to comment Share on other sites More sharing options...

Waynebaby Posted January 23, 2018 Report Share Posted January 23, 2018 Richard, My understanding is that Dynamat works best at stopping drumming/booming by altering the resonant frequency of the panel it's attached to. To attenuate the transmission of noise through a panel you need to add mass and to stop heat you need insulation. I've found that the best product to provide an effective combination of these properties is supplied by an outfit called NKThermal. It's called Lead Sandwich and is exactly what it's name suggests. https://www.nkgroup.co.uk/product/noisekiller-lead-sandwich-material/ Needless to say it is heavy (not to mention pricey) and you'll need to support the material on the underside of the transmission tunnel with repair washers. I've attached a picture of the material applied to my tunnel. It added about 5kg. Wayne Link to comment Share on other sites More sharing options...
dougbgt6 Posted January 23, 2018 Report Share Posted January 23, 2018 I used Silent Coat and yes, it is unexpectedly heavy. It also has the benefit of sealing all those holes in the bulkhead and stopping heat coming into the cabin. I'm hoping to get rid of my regulation GT6 shorts this summer. https://www.ebay.co.uk/itm/Silent-Coat-2mm-Bulk-Pk-40-Sheets-Car-Van-Sound-Deadening-Vibration-Proofing-Mat/151155678947?epid=1350639096&hash=item2331949ee3:g:Rx0AAOSw241YmyaU The gearbox sealing kit from the club shop is quite pricey, £30, for what is just draught excluder tape plus the screws and clamps, which should be recoverable from the existing instillation. The plastic tunnels on the other hand are very good value. Doug Link to comment Share on other sites More sharing options...
Guest Posted January 23, 2018 Report Share Posted January 23, 2018 Thanks Wayne & Doug, certainly plenty of choice [insulating material] with prices across the range. Doug - I agree, the sealing kit is expensive but I am assuming that the sealing strip is in one continuous length with moulded angles accordingly keeping the route of the box. I will give Phoenix Trim a buzz and see what they have, the rubber trim looks to be quite standard so hopefully PT may well stock it: http://phoenixtrim.co.uk/ 2017 catalogue attached. Regards.

Pete Lewis Posted January 23, 2018 Report Share Posted January 23, 2018 I have always ditched the silly rubber seal which will not seal the years of wonky metal and tunnel flanges and bought from places like dunelm cut from a 25mm thick sheet nice wide strips and glued them to the tunnel flanges this takes up and seals up every nook and cranny for good just an alternative idea and cheap !!!

Waynebaby Posted January 23, 2018 Report Share Posted January 23, 2018 Richard, As Doug says, the tape is not moulded to the shape of the tunnel and has a habit of lifting at the ends when asked to bend around corners. Not brilliant for the price. Here's apicture of the tapes profile: Wayne Link to comment Share on other sites More sharing options...
Clive Posted January 23, 2018 Report Share Posted January 23, 2018 Have a look at the suppliers up at Stoneleigh. There is always a selection of "stuff" available that can be re-purposed. There are some useful foam seals, and indeed insulation kits. I have found domestic carpet underlay to be very good. In particular the very heavy rubber crumb type, made from old tyres IIRC!. A layer on the cabin side of the tunnel, and something similar to the original "rockwool in a bag" underneath does a decent job. And in the past I have used a silicone sealant around the tunnel, surprisingly easy to cut with a sharp knife if you need to remove the tunnel at any point. Just a thought...

Paul H Posted January 23, 2018 Report Share Posted January 23, 2018 I purchased the sealing kit from the Club Shop and IMO it was not worth it - The peel off tape was not effective - To get the tape to seal I used Gorilla Glue - the one you wet then than add the glue - The glue then expands and the seal wont budge - Next time I would visit a carpet shop or find a draught excluder + Gorrila glue - Im another fan of Silent Coat and used it throughout my Vitesse - Brilliant stuff and half the price of Dynamat - Not sure if its been mentioned make a "door" for your gearbox level filler When using Slient Coat - preheat each sheet using an electric heat gun or hairdryer Paul Link to comment Share on other sites More sharing options...
AidanT Posted January 23, 2018 Report Share Posted January 23, 2018 Hi Some of the seals supplied (James Paddock for instance) are not that good The seal Wayne pictures above I got from Canleys in the end and found it to be much better. For heat insulation ( as i am a cheapskate!) I used radiator silver reflective sheet, and its worked very well Aidan Link to comment Share on other sites More sharing options...

Scrappies just don't want the stuff. For heat insulation, try to get a sheet of under-bonnet insulation from a higher-end car such as an old Beemer or Merc; it can be cut to size and again given away for pennies whereas back in the day it was hugely expensive to replace.

Clive Posted January 23, 2018 Report Share Posted January 23, 2018 Around here you are not allowed anywhere near a car at a "scrappie". Nearest you get is the sales counter.... Gone are the good old days or taking your toolkit and climbing around a pile of cars. I had assumed the rules had tightened up nationally, but it appears not!

Guest Posted January 23, 2018 Report Share Posted January 23, 2018 Folks. Very interesting and I appreciate the photos as well. I have a spare fibre tunnel box which is in very good condition, compared to the one I have just removed from the car. The original ST seal was shaped and either came as a continuous loop or butted up only once. Looking at the photos this is the correct seal profile for the tunnel, which appears to be quite generic as far as profiles go. I believe the centre edges should be facing each other which provides a guide to seat the securing "key hole" plates - I think !! Provided the seal is not too thick it should be possible to shape it in relation to the tunnel. Definitely worth contacting Phoenix Trim. Regards. Richard.

dougbgt6 Posted January 23, 2018 Report Share Posted January 23, 2018 Paul, Nice job on the Silent Coat tunnel, but it occurs to me you could extend the Silent Coat beyond the inside of the tunnel and bring it out to the edges using that as the seal?

Paul H Posted January 23, 2018 Report Share Posted January 23, 2018 Hi Doug - I did think of that but as already purchased the draught strip it was a case of using what I had - To do the job again I would use Silent Coat to act as a seal as well Paul Link to comment Share on other sites More sharing options...
Guest Posted January 23, 2018 Report Share Posted January 23, 2018 Mmmmmm, that's a good point Doug. So what you are saying, is bring the matting out further then seat it along the area that the rubber seal would sit ?? Would you secure via screws or some form of sealant ?? Regards. Richard.

dougbgt6 Posted January 23, 2018 Report Share Posted January 23, 2018 Richard, Yes, it came to me in a blinding flash! Fold it over the lip, it doesn't matter if it sticks out a bit, it's going to be covered by carpet. I've already have the clamps and screws so I'll use them. Sealant, not sure. If the tunnel has to come off again I'd use a Stanley knife to slit the sealant and would have to be very careful not to damage the Silent Coat. But I've got lots of it so, maybe. I also wonder about the gearbox access flap. Last time I had the tunnel off and topped up the gearbox I used a socket on the access bolt despite it being a square end. I have a cutter for drilling 2" holes (Recessed ceiling lights) It would have to be accurately done but, a neater solution than a great big square hole?

Paul H Posted January 23, 2018 Report Share Posted January 23, 2018 Here's another cheap solution - use a sleeping bag roll , place the gearbox cover on the mat and get a perfect sealing gasket Paul 1 Link to comment Share on other sites More sharing options...

The "keyhole" clamps / plates, I take it sit on top of the tunnel ?? So in essence you have: "keyhole" plate / tunnel / seal / vehicle bodywork / screw securing plate (cannot recall correct name) all held in place by the screw ?? Regards. Richard.
