Discussion
Has anyone ever heard of a wedge been turbocharged? Heard of the supercharged 350i, but I imagine a turbo charged 350i would be a lot of fun. Janspeed seemed to do convertions for the rover v8. Looking at the exhaust manifolds onmy 350i I would imagine space would be major issue.
Would be intrested on any feed back. What sort of power would a turbo bring to a 350i from stock 190bhp. Obviously pressure between 0.5 bar and upwards would make big difference. Would imagine the performance to be intresting!

Only done on two Ford V6s by the factory. Any V8 turbo-charged, is an 'owners addition' and modification. Not heard of one existing, but the topic has been discussed before. Perhaps a search over a long period could still bring it up.
When no further response, put it on the engine forum. Turbo-charging is often discussed there, with some very knowledgeable people posting. There was even a discussion on someone sticking two turbo-chargers on a Rover V8! Not on a wedge thou.

A famous Moggy Minor from the seventies had the Rover V8 with twin turbos.
What a machine !
Beautifully finished, street legal, and successful in both circuit and dragracing - bit of a legend.
At the time, was fastest 'street' car in it's class at Santa Pod, with Qtr mile in the eleven seconds bracket,
topping out at 140mph.
Oops - sorry it wasn't a TVR !

So it can be done, and the Morris didn't look standard after the modification either. Sort of a mid-engined Morris (not enough space under the bonnet, so it was put under the dash!).
Your choice to keep the wedge in one piece (euphuism?), or modify (turbo sticking out of the bonnet for example would be very impressive).
Just kidding.

It can be done using efi or a pressurised holley d/p and rising rate regulator. 5-7 psi will get you up to 50% more torque and you will be on boost before 2000 rpm pm me if you like. the car will drive like stock when off boost if you don't change the existing compression ratio.
Depending on space you can use 1 or 2 turbo's and you may need to relocate them via custom exhaust manifolds.

I have found someone with a supply of reversible cast iron manifolds from army forward control Landy's with the exhaust at one end which would be useful for this.

If it's the one I'm thinking of, it was also nitro powered.

Yep, they could help and you can also use a link pipe under the engine for a single turbo installation. Have you got a pic you could email me?
I'm planning a single turbo install using the Garrett T3 unit off a Renault 2.8 litre V6. It is water cooled.
The unit will be mounted low at the front of the engine right behind the twin fans. I have the early bonnet with the twin ducts at the front and will try to guide as much heat out through them as possible.
I will also be making the system dual fuel petrol and LPG for reasons of economy and performance.

Very expensive way to get more power.
You will need new flat topped pistons and possibly items like steel head gaskets.
There will be no room for a large single turbo (let alone ducting an intercooler) and the pipework and plumbing mods for two small turbos will be a nightmare.
Heat would also be a major problem.
It has been done, I am aware of several twin turbos and also a hi-boost single run on the RV8 but not in TVR's, all cars with more room in the bay.
Supercharging is slightly easier but still the most cost effective way for more power would be a capacity increase with a well built and set up engine.
(All IMHO opinion of course)
Edited to add also you will need a fully mapped management system or convert to carbs.

Tallbloke, and still with trailing arms?
Can here UJs and driveshafts snapping already....
Or did you plan an A-frame upgrade before?
And what about the brakes, already upgraded perhaps?
And we still like Wales.

I'm hoping that the Jaguar axle and TVR trailing arm suspension is stronger than that. I won't be cranking the boost pressure up to max straight away though
350zwelgje said:

No. If trailing arms are good enough for the Tasmin racers, they are good enough for me. Yes I have seen shpub's DVD with the 9 times fishtailing.

In about a week I'm
to the south coast to have 4 pot Wilwoods and vented disks fitted.

I like the welsh roads and mountains too.
These may get you started from ebay
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&category=10414&item=2486793944&rd=1
Look a bit handmade and not sure of the space required.
But doesn't half sound fun trying for twin turbos

Any info on your brake upgrade, looking to do the same later in the year, and based on south coast.
Who is doing it for you?
A guy by the name of Keri Purves in Bexhill on Sea.
Uses standard Ford Discs so is an economical solution.
Here's a pic of the kit:
email me through ph if you want to get in touch with him.

Wouldn't advise it. You'd have to modify the chassis rails. It'd leave the turbo bodies very very close to your precious bonnet too....

But the Tasmin racers have an additional bar added to be able to finish a race with a rear axle in one piece. I would at least consider that.....

I would move the turbo's forward ala Le Mans TR8 or fit them inbetween the chassis rails if that's possible then heat would be vented via the wheel arches? Would that be possible?

I've
this question a lot and concluded that a single turbo was enough for me, was much easier to fit, and would generate half the additional heat of a twin setup. One of the problems is that wherever you set 'em up, one of 'em is going to be too close to something which won't taste good roasted, fried or worst of all, flambeed
