Weight distribution
I'm still contemplating on the engine, I know a light setup is best but i was wondering how the Alfa 2.5 litre V6 engine would effect the
car's (Vortx RT) weight distribution, and most importantly handling. Given that the weight of the engine without ancilliaries is around 138kgs,
i'd use a Type 9 box. Engine won't realy remain in stock configuration, But will most probably have lightened/strengthened internals, for
higher revs, higher compression, some headwork, and run on a haltech ECU. Stock intake will go, in favor of TB's.
Considering that braking will be well taken car of, and the car would need a relatively soft set-up due to my country's state-of-the-art roads,
how do the handling Guru's envisage the car's handling? Any suggestions are welcome, so are different ideas.
it's either that V6 or a Busa engine. The V6 is cheaper

further.

If the front and rear tyres are the same size a 50/50 weight distribution is about right. If you are OK with having rear tyres wider than the front
there are significant advantages on smooth roads and with a skilled driver in having a 40/60 weight distribution.
If on the other hand not so able drivers have to be accomodated it reverses.
Hence road cars are generally nose heavy and race cars are tail heavy.
Good Luck!

That'd sound lovely!
Sounds like an interesting route to take - why follow the crowd?
Good luck!

Most sevens are about 50/50, with car engined cars being slightly front heavy and bike engined cars neutral or fractionally rear biased. Your V6 is
about the same weight as a pinto and there are plenty of them about.
having more front end weight may help braking although a heavier car will make it worse. probably the same overall.
having more front weight will meal less traction at the rear. a bit.
There is loads of grip but with more weight at the front you'll start to lose grip slightly earler.
basically, you'll be fine.

ohh nice engine.
I have driven a GTV with a 2.5 v6 and a 33 cloverleaf with a 3.0 v6. both were absoloute screamers Mr Clarksons rule of 3 fits well.
regarding the weight distribution in a Vortx you will have no problems I would suggest going inboard as the springs can be adjusted to get the ride
spot on. can get mine with the v8 50/50 with me in the drivers seat.
MNr would require the engine and box for chassis finalisation.
extra costs or problems that may need to investigate. exhaust X 2, steering column. gearing final drive with type 9 ratio's
owt else give me a shout.
all the best Agriv8

... better still I'll try and visit MNR this winter. But the company i fly for stops it's charter flights to Leeds/Bradford during the

re the donners would still need gearbox and bellhousing v6 to type 9 as this will depict how far back MNR can get the engine.
if you do get over let me know or get marc or chris to contact me and if I am back on the road will take you out in the V8 wont rev like the alfa but
makes all the right noises.

There is a guy in the Forum, who built a viento with the 3.0 Litre V6 and a type9 box, so hopefully i can get some help from him, re the bellhousing.
I don't fancy shipping an Engine and a Gearbox to the UK from Malta  ... expensive!!
Although i will take a quick trip to scicily with the ferry to buy myself a spare V6, they are cheap there. Tune it up ... italian hillclimb style
(9000 rpm limit, high comp., 300deg duration cams, smell of racing fuel,etc ... it's so nice to dream)

ideal world we would have the engine and gearbox so we can place all the mountings there no fabricating / making on the customers part, just bolt bits
together
also when we mount the engine we can place the chassis on scales to get the perfect position for the weight distribution

Well ... hopefully i can find a doner, well maybe just the engine, I won't be using the stock ECU anyway, and a Type 9 gearbox from the UK ...
so that you can use it during the chassis fabrication.
I'm doing my best to visit you this winter i promise I just cannot find any flights to leeds/bradford in winter ... it will have to be
manchester, and a whole lot of trains!!!
