Vixen vs 3000m fast road car
Discussion
agreed to that, I would also go for the more modern alu (Ford) V8 in a TVR if "possible" .
you also hear and see more GT40 replica builders using such modern engine, for example the Ford Coyote 5.0 engine with 412hp to start with?
but maybe such engine is to wide in a TVR ? don't know but it sounds like a nice engine.

here also a Vixen with a more modern 302 (5.0) engine, although not so great looking as the Coyote engine it gives the car lots of power and less maintenance I guess, me like.

and below a example of how a coyote engine could look (NA)
how clean would that look under your bonnet

Don't forget...
302 has cast iron heads and intake in std form
A re-furb or crate engine built with alloy heads and intake is considerably lighter than one in standard specification.
A block on its own is relatively light but you still need pretty big b
ks to lift one. block for block a little essex is lighter than a small block, again allow for heads and inlet.
the biggest advantage of the small block ford is the narrow angle and distance between the exhaust manifolds...
What I don't understand though is if anyone is building and modifying a road car and not subject to any racing regs etc then why does everyone seem to want to use such antiquated old crap. There are a lot of modern very powerful 4, 6 and 8 cylinder engines out there very cheaply available..
Duratec V6 powering the current ginettas for example??
even a Duratec 4 cylinder Turbo in a vixen would likely as not trounce a V8 car??

however, on an old car (60s) keeping and modifying the original engine may help with residual value of the car
Second, as i mentioned earlier i have had some problems in the past trying to get good insurance quotes for heavily modified classics. (classics running more modern and powerful engines)
apart from that, the Duratec (I4 or v6) engine would win hands down..
not to talk you into something V8, but just came across this, also a more modern Ford V8 and is new with all parts incl gearbox, sounds very cheap maybe for someone else on PH

B, thanks for the thought, but I have the Vixen racer coming together and 2 drivers to 'prove' it when it's ready, and hopefully I can get through the 'normal' work too.

And we are back to the purpose .... :-)
Big V8's in a light and short wheelbase car.... scary, with my 240hp/800kgs with LSD and wide tyres, good traction and very fast in the dry. On damp roads in the morning - wheelspin at 50 mph in 3'th gear, and you'll wake up - fast! ANd with more weight out front and more torque it will be a handfull to drive.
My plans of adding a supercharger to take it to 350 hp is back in the drawer. Not claming that 400+hp in a 800 kg car can't be fun, but mostly for trackdays and short spin's. But after all I'm a chapman fan "less is more" :-)

i would have to agree with u Mads
approx 250 bhp per tonne would be about right, to allow for a predictable fast road car. A v8 would sound amazing and have a certain appeal, but in reality it may make the handling worse with that heavy lump and the extra power probably un-necessary and not useable
my G4 has 240 bhp per tonne (weighs 510kg) and it can outhandle most other machinery old and new.
how did you get your 3000m down to 800kg Mads?

Or one of these which will similarly be just as easy to fit
Seriously.... engines are selected based upon their physical size, weight and then power output. Have you seen a SOHC Ford V8 ?? Thats why there are loads for sale ...Nobody wants them.
if you want the fastest road going vixen which handles nicely then fit a Modern 4 cylinder Duratec engine. If you want an insane car then turbocharge the Duratec. if you want a period looking fast vixen then stick a replica BDA cover on a Zetec. If you want an economical fast vixen then fit a 1.9tdi Audi diesel engine.
Find yourself and buy a car first though please before we have anymore inane internet twaddle spoken.
I have just decided that my next vixen will be 4wd. Too many people re-inventing the wheel..I need to do something different. Probably a Diesel as well to upset the purists as well FFS.

I'm sure I remember seeing a 4WD TVR for sale, think it was an M series though, using the Ford Cosworth 4x4 gear, quite a few years ago now though.Or one of these which will similarly be just as easy to fit

Someone over on The Mini Forum suggested putting a diesel into a classic mini a while ago, I think there was nearly a lynch mob,
, but with the number of diesel skodas that have outrun us in the 1600M it probably wouldn't be the worst way to go, Cerberus90 said:

how did you get your 3000m down to 800kg Mads?
Not that difficult, out with the cast iron engine and gearbox, and in with an alu lump, the jaguar S engine with gearbox and manifolds is 175 kg compared the essex drive train is around 235 kg in total. Further did I loose weight removing the spare wheel and a bit on the brakes, diff drive shafts and suspension (even it ust a few kg's). how did you get your 3000m down to 800kg Mads?

also i have heard great things about the ford ecoboost engines, but maybe a bit too complex an installation

and here something with/about TVR and Ford Zetec engine's , they also use Zetec engine's in one of my other favorite classic cars the Lotus Europa say type 74 etc.
they also talk about the duratec option etc>
