seight, some of the information stated on flukes site needs to be taken with a pinch of salt i'm afraid, it's not flukes fault as their dependant on individuals posting correct info. Actually on flukes sites another individual states their T9 box weighs 33kg without stick and oil, which is what I know mine weighes. I suspect the 45kg comes from steel bellhousing, oil, gear lever, knob, brackets and 7kg of dirt
"A really decent lightweight 'clubmans' type sportscar, even a front engine one, ought to have a rearward weight bias! "
I agree with this totally and so would all good geometry specialists

Martin S needs to drive my V8 Ginetta G27 to know he is talking Bo**ox re v8`s versus others
Its as quick as a griff, (quicker in third) and will slaughter most cars (seven type excepted but will match them) in braking and cornering.
Why do people have this myth that seven type cars corner quicker. Some do but loads dont. On crap tyres with a crap driver anyone will beat them.
Fury`s or G20`s etc will equal or better most sevens when set up properly.
I got rid of my Westy (Vx powered) cos it was always in the wrong gear at some of the corners on circuits whereas with the torque characteristics of the rover V8 you are rarely in the wrong gear and even though the westy was bloody quick, at over 80mph the car died due to cr*p aerodynamics. All sevens suffer from this but with a torquey V8 will pull harder for longer.
Mallory type sprint circuits are for sevens etc but get them on long circuits such as Bedford Autodrome or Silverstone (full circuit) and they are pants (even Caterham Duratec 500 superlights) cos they are as aerodynamic as a brick wall. They might get to top speeds but only slowly but with a V8 they get there quicker, nuff said.

A 'sensible'(Rover K-series, Toyota 4AGE or Ford Zetec?) car derived engine for a '7' should weigh in the region of 100 - 105Kg max.
Can't agree with the 4AGE engine being a sensible choice, very difficult to get good power (200 bhp +) out of them and they have been known to break. Same is true of the K-Series, it's pretty expessive to get over 200 bhp from them and they're less than reliable in any state of tune. Zetec is the new Pinto, average and still low-ish power.
If you're looking for low weight and good power then the Hayabusa is the only engine to look at - small enough to fit into even a narrow bodied car with space to spare, can get an easy and cheap 200+bhp, comes with a 6 speed sequential gearbox and the whole package is about 85-92 Kg including gearbox, depending on who weighs it.
It's bomb proof, fantastic design and with a turbo will give an easy and reliable 400 bhp.

And you can pick them up complete with turbo, necessary dry sump system, and a Quaife reversing gearbox, for £50 a piece down the local scrapper!

Own up, you've got shares in the company haven't you!

Yeah, there was an AJP (Cerbera) V8 engined Phoenix built IIRC.
Don't know what became of it, but it failed to set the racing world alight for whatever reason. The AJP V8 is considerably lighter and more compact than the Rover V8, too - nice engine, if you can afford the rebuilds!

That's ridiculous as you know I have no way of qualifying the measurements supplied to fluke, so it's easy for you to rubbish them by making such daft comments.
If you read it, my point was that V8 gearboxes are not much heavier than those used with other engines, with my fully loaded T5 box + bellhousing weighing 42kg.
V8's rule
seight, you have stated a T9 gearbox weighs 45kg, because someone has posted this weight on flukes website. now if you look at their website someone else states a T9 weighs 33kg
I dont care that you think I am rubbishing this information, because
I am telling YOU that MY close ratio HD T9 5 speed gearbox weighs circa 33kg, So there

Calm down
If you read
fluke's site you can seen it says type 9 from a 2.8 and N3 class, is that different from yours? I deliberately chose that figure as it is clearly a heavy version of a box not usually fitted to V8 'clubmans' and everyone assumes if you have a V8 you will have the biggest/heaviest gearbox.
Perhaps I will get in touch with them and ask if it had "7kg of dirt" on it
Arnie Webbs 6 speed weighs 37kg without oil, perhaps he's actually got a V8 in his car. You stated a close ratio T9, which is what mine is and it weighs circa. 33kg.
FWIW, the 2.8 N3 is not used for a close ratio box, unless someone specifies it as a one off
You state "I deliberately chose that figure as it is clearly a heavy version of a box not usually fitted to V8 'clubmans' and everyone assumes if you have a V8 you will have the biggest/heaviest gearbox"
Youv'e got me on that one, why state a weight of a gearbox when its not usually fitted. Especially in context with the thread, which is reference to a V8 lotus 7.

you really need to weigh up your options,are you going to use it regularly on track days,or as a weekend toy on the roads to have a bit of fun
most people would be happy with the beautifull noise and torque characteristics of the rv8 lump,combined with a sorted chassis and suspension set up you have a very capable and fun road car
