Time for a little update, i tried to fire the beast up recently and she wouldn't catch.... too many people coming to the garage and wanting to hear it run for 30 secs left it so badly flooded it was drowning in petrol, plus my super rich base maps were making matters worse. So before Xmas i spent a day taking plugs out and had to set fire to the bores with a gas torch to get them clear.... it was like that scene from "flight of the pheonix" when he uses one of the cartridges to clear the cylinders!

Whooomf! huge flames shooting out of the bores, wish i'd got that on film, it was awesome! Anyway with the bores clear and plugs dry we got her started again, i'd forgotten how loud i'd made this car, and although it's an amazing thing to hear i just don't think i could live with it for more than a mile at a time, it really needs quietening down. The problem is the single TVR 350 silencer just isn't doing a good enough job, it needs more silencing! Burn the heretic i hear you say... and i agree, it does sound godlike at the moment, but i need to be able to drive this thing.

So i've decided to revamp the exhaust system, i've already lost the boot as it is to the TVR box which leaves me a nice space just behind the TVR box to place a secondary silencer. Hours of trawling Ebay and a crafty bit of bidding and i'm the proud owner of an Audi R8 rear silencer, what better silencer can there be!



It has a perfect notch out of it to fit around my transmission and the plan is to keep the TVR box but plumb the outlets from the TVR box into the inlets of the R8 silencer, that should tone it right down and make it sound fantastic.

A little bonus is that the R8 silencer comes with vacuum actuated valves on one of each pair of tailpipes, this is awesome, i can plumb them up to VSV's that i can program from the VEMS to switch at whatever load/rpm i fancy, meaning it will take on a totally different engine howl at higher RPM.... i might even use the output from the current induction VSV (Audis version of TVIS/ACIS etc) so that as the induction note changes so does the exhaust, exciting stuff!

The plan is to hit the project hard again in the new year, i've neglected it a lot, but it needs finishing this year, so watch this space for plenty of updates.

A days bodywork doesn't seem to go very far but it's progress all the same, i managed to block down the previous guide coat of high build primer to reveal a few more bellies and ridges in the bodywork, stuff that normally gets left during a regular respray and you'd hardly notice unless you have an eye for this kind of thing, but on this car i'm aiming for perfection on the body and panel gaps which are all going to be mm perfect.


Not a lot to see in these pictures but such is the nature of sanding/filling/sanding/priming etc...





A lot more work done on the bonnet vent, it had quite a wavy front edge due to distortion from welding, i won't be happy until it is marble flat. I also spotted that one of the leading edges of the bonnet vent tapered more at the top by about 2-3mm than the other side, so i've started grafting that to make them equal, again it's stuff the regular man on the street would never notice, but i know it's there.





Got the structural fibral in on the sill edge, this will add a lot of strength to my sideskirts and prevent them cracking.





An overview of progress, i reckon another few skims of filler in certain areas and it will be close to its last high build primer coat, then i'll get some colour onto it.

More mundane bodywork, the drivers wing arch/bumper area needed more work so i spent a bit of time on that, remember all of this filler is just cosmetic.



The passenger sill/doorstep that was previously fibral'd was sanded and given its first filler layer about 2mm thick.

More work done to the passenger side which is very near to completion...



Final checking of the panel gaps around the wing/bumper/bonnet and lights, all looks good...



I had to remove the windscreen to carry out a top edge roof repair...



It wasn't too badly corroded but worth repairing properly anyway...

Seeing as the screen was out i decided to paint the front dash scuttle, this was originally a blue interior car, so this was the last unreachable area of blue, which is now painted satin black...



Overview of the front end now...



So she's getting there, i think there's maybe 80 hours bodywork left to get it to the standard i'll be happy with.

Thankyou for the kind words, the work itself is nothing special though, keeping motivated all these years is the hard bit.

Mini update, this car has never had a rear antiroll bar solution, the fact that the transmission sits right where the stock ARB would go has meant i had no way of getting a Mk1 or Mk2 ARB to work. I've scoured the internet for over a year now looking at hundreds of possible ARB solutions to the problem and had almost given up and was faced with having to have a custom made ARB when i saw this...



That right there is a godsend! It comes from a Nissan Terrano II , has just the right hump in it to clear my gearbox casing and can be mounted right back at the rear of the chassis legs.

How will it affect handling? I honestly don't know or care, after all having an anti roll bar of any description has got to be better than no bar at all. I'll get this fitted next time i work on the car.

It all depends on how the car handles as a whole. Some guys only add a rear anti-roll bar if they need to balance out a front understeer. I am guessing but your back end is probably heavier altogether than stock, but you'll have lots of rubber on the road back there, so... It'll come down to some road-testing :) But I am rather new to the handling game, plenty of others might give you a decent prediction.
It's great you found one that works though!

Yes i'm pretty much in the same boat as you Gandalf when it comes to my experience in such matters, and to be honest i think everyone is in this case due to the uniqueness of this particular car, who knows how it will really handle and wether a rear ARB is even needed.... i guess i'll find out :)

Thankyou Fuzzy, i'll never give up on it, too many of these builds stall, my problem is finding time to do this alongside my daily garage duties, so it's restricted to odd Saturdays and holidays, but it'll get there.

Today saw the old TVR exhaust system removed (just too loud!) and the start of fitment of the Audi R8 system starting with removing the upright supports to my crossbrace (yellow), these were right in the path of the new manifold to silencer pipes.

I will redo these to miss the exhaust pipes and repaint them, sometimes you have to undo a bit of your hard work to progress, such is the nature of an evolving project i guess.



Also i removed the last of the old boot floor (red), the Audi R8 box sits over the transmission in this area, i figure i'll have much better airflow around the silencer to keep things cooler anyway.



Here is the Audi box in place, i have removed the tail pipes, these will have to be rerouted behind the box, down and out the rear, a bit of fancy pipe navigation and flanges will do it, and the actuated valves will be staying, they're pretty cool and will help with low end torque... yes cos that's the one thing i need more of :D





So the boot is now totally dedicated to exhaust, bang goes my small storage area, oh well!

Ain't that the truth.

Well, you still have the frunk, right? If you really do want storage still, maybe you could move the donut spare to behind the passenger seat, if the firewall has not come forward too much.
