Jaguar/Locost
speedyxjs - 1/2/07 at 12:48 PM

Hi Everyone
i run a 3.2 jaguar x300 and i was wondering if anyone has ever attempted a jaguar as a donor car or anything similar? (just think of that power in something as light as a locost )

Me too the prob with the jag engine, as good as it is, is the weight of the bloody thing
As near as I can tell it is over 200Kg's even though it is all alloy (liners excepted) as it was designed around a possible diesel option so was over engineered for the job in hand.
But apart from that it would an interesting choice, although some extra length and strengthening would be required in the engine bay, and possibly some suspension mods to cope with the extra weight, use the manual box (Getrag I think?) and avoid the rear suspension/diff unit (as heavy as the engine!)

Cheers
Alex
PS
Just read that back and realised why no one has done it

Within in reason, you can put anything into anything but the appeal of the Seven type cars is their dodgability, able to change direction and corner with no fuss or drama. This is because of their low weight, always Colin Chapman's target, built in lightness. Put a heavy lump in the front and you have a different animal. Somebody once said, " All you need in a Seven is 80 BHP, any more is wasted". The Seven is a wonderful country lane car where good acceleration and cornering can be used to the full.

It will be interesting to hear what others think

A friend of mine races a D-Type (and frequently wins!) and is coming on a se7ens tour with us this year in his Jag. I'll let you know how he gets on, though I'm sure his grin will be as big as mine!

p.s. He frequently beats a lot of se7ens when racing, including pulling away from them through the twisty bits!

I remember seeing a Jag-powered '7' in a magazine once - "typhoon" rings a bell, but I'm probably wrong.

I do remember that it was low and wide, and an incredibly mean looking beast!

I had a XJ 3.2 nice car and great engine.

All alloy so i think in might be lighter than you think, loose the cast manifold and all the excess stuff and it could be a real flyer.

Plent of room in the Viento bay.

The Jag powered Robin Hood was an early monocoque with a V12 in it, must have put the engine on blocks on the floor and welded the body round it.
It was up for sale the first time the company changed hands.
Must of sounded great but would have handled like sh*t with all that weight up front.
Sevens should be light and agile, save the big engines for Cobras, GT40's and the like.

I think the best bet would be something like the Vanwall (?) Jag V12 thing they had on Top Gear. That would look and sound the part. Bodywork could be a real PITA though. If I could form the bodywork, I'd make one tomorrow.

I wouldnt touch the V12.

Heavy , wide and prone to oil leaks and crankshaft seals going.

The 3.2/3.6/4.0 straight is a great engine.

Ill bet it weighs no more than about 150kgs with out the ancillarys, silky smooth and 3.2 =230 bhp easy.

All alloy and modern design.

V12 is for best left in the Jag.
