What does your engine weigh?
Also, does anyone know what my 2.9 aj6 jag engine weighs and what a 4.0 supercharger aj16 jag engine weighs?

Alfa 136 kgs with no Ex manifolds and alternator etc.

aj6 is a craking unit and all alloy,

v12 is 309kg undressed so its going to be a minimum of 200kg !

2.9 had a v12 cylinder head, not very good, the 3.6 and 4.0l DOHC's were much better, I had a 4.0l XJS a few years ago, went really well, faster than the v12 it replaced as it was a rare factory manual. Should never of sold it

The only figures I ever found for the aj16 engine were about 220Kg, and that was reputedly bare i.e. without injection, chargers, alternator etc etc , not sure about aj6 or the 2.9 but I would imagine the 2.9 would be slightly lighter being a single cam as against a twin cam (is it still a ally head on the 2.9?)
So a serious lump of an engine, but when you see (and lift) the crank from one you start to understand why
It was apparently designed around the possiblilty of a diesel variant being introduced, so the bottom end was over engineered just in case (which will be why they run forever when looked after).

PPC did an engine swap article a couple of months ago. I'd love to quote from it now but i'm away from home. maybe someone else can help out.


PaulBuz - 25/3/07 at 11:14 AM

My Sierra DOHC is 135kgs dry.


martyn_16v - 25/3/07 at 12:14 PM

Mine feels like it'll compress into a black hole at the end of it's lifetime. It's certainly got it's own gravity, everything in the garage seems to have clustered around it

http://www.team.net/sol/tech/engine.html

two websites with information on engine weights iv had them both bookmarked for a good while now, he first one is just an extended version of the second one i think


NS Dev - 26/3/07 at 07:36 AM

depends which car!!

in the 7, Vaux XE, 115kg ish

in the class 7 grasser, 58kg all up with ancills, manifolds etc................................but there are two of them so 116kg, but then that's not bad for 300hp!


MikeR - 26/3/07 at 02:33 PM

so let me get this straight,

200hp for 115kg
300hp for 1kg more .........

wowsers - what a performance upgrade

(in case anyone who doesn't know the upgrade is two completely different engines running in parallel)
