Engineering Questions???

[CORTYA]

Hi All,
Let me start by saying what a great site! I'm a passionate Mk1 Cortina freak.. And have regularly visited this page for a while now, but only recently become a member. Probably due to the fact that i have recently decided to undergo a major buildup of 1 of my 2 Mk1's and could do with the interaction, references and of course advice etc etc...
I will post details of my planned buildup and hope for feedback, bye for now.



KEEP THE DREAM AND THE CORTINA ALIVE...

[CORTYA]

Hi,
My questions involve one of the first choices of any buildup, that is power plant.
For me this is the question i have been thinking of for a few years now (had the car awhile).
As much as i can appreciate a well engineered MK1 with efi inj possibly turbo or even a rotary (all have been considered). I've decided to go with a V8 Windsor (if its possible @ all)?? This car will hopefully be VASS engineer excepted, and victorian road registered to comply with the fitout.

I'm familiar with modifiying vehicles that have been road registered in Victoria before, but, not under what i understand is a newer system (VASS).
I do understand that a vehicle has to be approved, inspected and meet all criteria required by the the specific guidelines contained within the "VASS" and by it's approved signatories.
I intend on having the vehicle modified by a skilled and experienced engineer and myself. Along with the requirements of the VASS, but my concern is i no longer can find details on power to weight ratio's (max. engine capacity) for the intended vehicle.
The vehicles Year of manufacture is 1967 (Ford MK1 Cortina)
Gross Vehicle Mass is 1100 kg
Tare Weight is 800 kg
Production engine capacity is 1200 cc.


It is these circumstances that have prompted me to ask, is it all POSSIBLE to have a 4.9 litre or even a 5.8 litre, 8 cylinder fitted and be approved?? Do "VASS" participants opinions vary and therefore some may consider approving what others wouldn't?? Or is there a uniform standard??

Regardless of capacity, if i fitted a dissimilar engine to that of manufacturers intention to a vehicle, must it run pollution gear according to the engines requirements for that year?? Or according to the intended vehicles date of manufacture?? What if the engines an import, what then??

Once im aware of the allowed engine capacity i can then commence the critical processes of building the vehicle.
I thought a little preparation in advance to meeting an engineer which can be costly if you have to see a few or more just to establish if they'll even consider it! Would be better for both parties.

I thank responders for their patience and understanding in my concerns. And look forward to your advice and maybe possible business.



Regards CORTYA.

here is part of the formula used in selecting an engine for transplant

first you must take the original weight of the vehicle

vehicles (original unmodified tare) weighing less than 800kg (1764lbs)
naturally aspirated = car weight X 3.0 = max capacity in CCs
turbo or supercharged = car weight X 2.5 = max capacity in CCs

vehicles (original unmodified tare) weighing between 800kg (1764lbs) and 1100kg (2425lbs)
naturally aspirated = car weight X 4.0 = max capacity in CCs
turbo or supercharged = car weight X 2.75 = max capacity in CCs

vehicles (original unmodified tare) weighing more than 1100kg (2425lbs)
naturally aspirated = car weight X 5.0 = max capacity in CCs
turbo or supercharged = car weight X 3.0 = max capacity in CCs

not based on a station wagon
sedan models only

example

4 door deluxe mk1 861kg

861 x 4 = 3444 cc NA
861 x 2.5 = 2368 cc turbo/sc


so cortya i would have to say NO its not possible :(

but, a 3.5 litre rover V8 would...

HI Jewels,
Thanks for the reply, NOOOOO!! you shattered my dreams with that info. Is it gospel? (if so what reference did you use?) or are there conditions that could be met to persuade a VASS signatory.
Are all the windsor mk1's & mk2's ive seen registered on victorian streets illegal or created prior to thie VASS scheme?
Upon contacting most Victorian Vass signatories giving them the same details i posted, a few have responded saying they should be able to help! . Most have said they too busy, not their area etc. One even suggested i read the National Code Of Practice & if i thought my project met the criteria we could go from there (was he taking the piss outta me??). Now these NCOP's are hundreds of pages long (could take awhile lol).
Do you think they're genuine or just trying to get me to come in, pay the consult fee (which usually is at least $100>)then think about the proposal and say no, EASY MONEY...

well sorry but that is based on their own documents

one thing to remember
how is a engineer really gunna know the capacity of the internals?
hes not is he ....

they did make 260 cube windsors

they change the rules so often ..a couple of years ago this wasnt the case
but its certainly in know for all 'new' engineered cars

[bollo]

all the info about conversions is very useful; how is it calculated for a rotary? Is it the same as turbo-supercharged at 2.5, 2.75 and 3 x the weight of the car respectively?

Is a 13B considered to displace 2.6lt? and a 12A 2.4?

[jewels]

bollo thats a good point...

i think yoiu will find that if any sort of 'power adders' are used will reduce the capacity even more

[`65 GT]

Hey, I'm new here. Looking around today for brake and suspension ideas for my 65 GT.

Thought I'd chime in about 13b and 12a displacement. Here in the states a 13b is 1.3l and 12a is 1.2l.

Not that I can visualize what a liter looks like, as i grew up on gallons and odd sized soda cans.

I do however have a 65 gt with a ported 12a and early rx7 trans, stuffed into a pinto 8inch with the 2 short axle trick.

Love the car, would like to make it stop and turn with a bit more confidence.

Thanks, this forum has given me some great ideas today.

With the Aussie dollar you may be able to grab a bargin.

I believe they made a 221 cube Windsor in 1962 for the first of the "compact" Fairlanes, that little beggar would fit the bill just right I'm thinking 221 cu.ins = 3.4litres at about 61cu.in/litre. I'm constantly amazed at our "Merkin" cousins and the capacity of some of their engines still I suppose 7litres sounds a lot more impressive than three gallons and one pint (imperial) although 25 pints sounds pretty big! Someone else can convert that into US gallons if they're feeling inclined!

i think you are right nomad... i will do a search on the net to find some more details

Guys i too have been looking into this for quite some time now and after sending letters and phone conversations with vicroads i have discovered that the above formula is only a guidline vicroads have asked engineers
to work off. I have found an engineer which was a little reluctent in the begining but after i let him know that i know that the formula is only a guidline he has agreed to engineer my car with a 302 windsor in it. So dont give up with that windsor project just keep perciveering.
