Engine Height - Hypothetical Q
speedyxjs - 29/1/09 at 11:33 AM

If an engine (V) is 24" high (just the engine not in chassis), and one was to use down draught carbs, how tall would the engine be and if it was an issue, what would be a good way of getting through IVA?

You could put the seats on stilts so you can see over it. That's one tall engine set up.

Its about the same height as the engine i have atm but the engine is about 3 or 4 inces below the bottom chassis rail to compensate.

Out of curiosity, how tall is the average pinto?

I thought you had a straight 6? carbs are side daft or are you now going for the v12? and it would be about 2 1/2 foot tall once the air filters were on, think the back of a ferrari

Shhhhh, dont tell everyone
Iv been learning about calculating weight distribution at college and with a V12 and auto box, it works out about 60:40 split front to rear.
It started with people on another, jag related forum persuading me to drop the crappy 2.9 and go 3.6. The V12 is apparently only 80 kg heavier than the 2.9.
Im going to buy a V12 to rebuild as a side project but at some point, various parts might find their way into the engine bay as a trial fit
For now the below still stands

Wow, that does look tall
Might have to go side draught and have side bonnet scoops then.

Iv got loads of steel left over so thatll all go into triangulation, make the chassis seriously heavy (for a seven) but still much lighter that an XJS. Im going to get one of the college lecturers (engineer) to check the chassis after triangulation to be sure.

the injection looks a lot lower here's a link to a jag power MGB!

Thanks for that. My midget i used to have was about the same height (engine bay) and i assume the 'b' is about the same

How can i contact that guy with the V12 miata?

Thanks Whippy
Iv just found out that the V12 is only 67.59 kg heavier than the S6 i have atm which is less than i originally thought. I think the hardest part will be making it fit in the space availiable but i like a challenge

Do you think this will stick too far out of the bonnet?

alistairolsen - 29/1/09 at 01:02 PM

does anyone know offhand the height from the bottom of the chassis rails to the rear top edge of the nosecone on the highline locost bodywork?

Cheers

So it'd be like having a 10 stone 9lb passenger in your car all the time...

Hi

Here is a Renault V6 in a Westfield. Cant recall the exact height of the engine without the carbs ( Porsche triples ) but the engine was under the bonnet easily with a flat floor. Needed a periscope by the time the carbs and filters where on though.

There's a load of pictures of the engine in the chassis in my archive under the Westfield header.

V12 injection is fine, no taller than you already have and no harder to megasquirt.

The JAG injection is banked, cylinders grouped in three's 4 banks banks fired in pairs with no regard to engine position.

Big distributor, single coil.

Really really heavy, I have pulled out of an XJ12, not worth rebuilding as the costs would be huge, get an rotten car and strip.
