It does explain why those honda converted elises that have been weighed have come out pretty similar to pre conversion though.
not from what I hear…
From the S_E bb:
Dodgy weighbridge data; lets see then.
Car weighed on weighbridge in Scotland 743kg’s which is about right
for an S1 99MY give or take a few kg’s. I also had the car corner
weighted in Scotland a few years ago and it was in the low 740’s.
Car weighed on scales at Sinclaires, 870kg’s including me. This
wasn’t right so checked with them and they had written the off side
rear down incorrectly so actual weight 850kg’s with me. I weigh
70kg’s that makes 780kg’s for my car post conversion. Just to check
though, I took the car to a local weighbridge and guess what 780kg’s
(I stepped on and off the weighbridge and it varied by 70kg’s so
reasonably accurate in my book) Therefore, 37kg’s heavier.
Komotec Honda S2 at the Ring posted his car was 816kg’s post
conversion, 778kg’s pre conversion so that’s 38kg’s heavier.
Ian Wilson said his was 775kg’s post conversion. He drives an S1 as
you know so best case it’s 25kg’s heavier as his car is unlikely to
be heavier than 750kg’s pre conversion and probably lighter.
However, given that his car is 5kg’s lighter than mine post
conversion, lets assume that it started off 5 kg’s lighter as well
which would make it 738kg’s; which makes it 37kg’s heavier post
conversion. Now that’s a big assumption to make but there’s a bit of
a pattern forming don’t you think?
Incidentally, unless my ex girlfriends have been bragging about me
on the Internet, I have no idea who King Dick is although will
hazard a guess at Uldis’ engine builder bloke. I also checked with
my neighbour; he doesn’t know how heavy my Elise is so I guess the
whole World is slightly exagerated.
Clearly the Honda engine isn’t the boat anchor your Regally endowed
friend suggests. I am, however, having a tough time believing the
conversion adds <20 kg’s to the overall weight of the car which you
assert. This would mean that my car would have started off weighing
at least 760kg’s, even late model S1’s didn’t weigh this much and I
already know it didn’t. Therefore, we can agree that straight away
the <20kg’s increase (for the conversion) is bollocks right? Now
this isn’t quite as bad as the Thundering Horses you keep referring
to but it’s still inaccurate.

some dodgy weighbridge data) is not exactly helpfull…
Hence going to the trouble to actually weigh the engines etc. I
know that there is not that much in it…
I have to say I was somewhat supproed with the gearboxes, to the
point I did it 3 times… the Honda one is physically bigger too, I
guess they are used better design internally?
I can’t remeber what my K weight dressed, but that would not be much
help anyway as it was very much lighter than std.
by next week I will have the exact std engine weight foe the K as
fitted to an Elise, hopefully this will nail this subject closed!

It’s a lot of trouble to go to…although you are trying to prove a
point I guess which is fair enough. All I can say is that my car is
37kg’s heavier, the Komotec guy’s car is 38kg’s heavier and Ian’s
car was 30 something kg’s heavier. Therefore it seems reasonably
safe to assume that the WHOLE conversion as fitted adds at least
30kg’s. Some of the extra weight must be in the exhaust as the
silencer is pretty big compared to the old Janspeed plus I have a
cat fitted rather than a cat pipe so that’ll add something as well.
