Hello Guys,
Thank you so much for those good suggestions!
For those active vee performace lover; I have my opinions as following:
1. Cheapest way to get 300hp or more; .... by supercharge
2. Weight lowering .... to enhance handling.
For the first topic:
I take supercharge rather than change engine is because mounting is not easy and all engine , gearbox and others cost too much. In my country, change different engine is not allowed but adding supercharge would be easier for not being checked out. So keeping the standard engine and adding a suitable supercharge (small one) and fix a good size pully can boost power to or more than 300hp without changing too many origanal parts. One side of the in air panel could be used for cooling. ECU might not need to be enhanced for oil supply, but oil pressure regulator, may be needed. If still not enought, than extral ECU. The problem, I concerned is the gearbox...... any suggestion?
Also, if not use supercharge, then, I don't know whether we can find any suitable engine internal up-garding parts, like: ......conn, piston, valve guids, spring etc. I think engine polish for in and exit air is needed too.
2. Weight lowering:
I think all we agreed that our vee is too heavy at the back and relatively light at the front, so anything of weight reducing for the back is good! and lowering a few cm for the engine also ok.
What I have done is:
a. Airbags safed almost 10 kg,
b. carbon door panels (two) 10 kg,
c. Hi Fi 6 to 8 kg
d. manual window regulators and mirrors 5 kg
e. engine top cover ( those plastic ) 8 kg
f. budket seats ( 30 to 40 kg )
g. A/C 15 kg;
h. exhaust 10 to 30 kg (steel or titanium)
i. Finally subframe change to titanium 30 kg at back
Those, weight reducing should greatly change the weak of vee handling and enhance good control for such a nice looking car. My target weight reduction : 1050 kg . That is my opinions and wish you guys could give me some more good suggestion see how to futher improve our lovely vee! [smilie=yay.gif]

It's a shame you haven't subscribed to membership because there is access to Max's rebuild (hard-core weight loss programme) and some information on MikeT's supercharger (and the costly problems it brought).

I can take no credit for my Vees' specification, as the work was commissioned by TimV6. The orginal goal was 300bhp...
It's a symphony of aural delight! [cmilie=iconcheers.gif]

Getting rid of nearly 300kgs is very hard especialy if you still want to keep the car practicle. You'll most definatly need to get rid of the glass and replace it with polycarb or the like. That's a BIG ammount of weight removed. Carpets and general interior will probably need to go as these weigh about the same as most mid atlantic container ships. The engine covers don't seem to weigh that much if I remember. I certainly wouldn't ditch them all together. Maybe replace them with Carbon ones if you fancy saving about 2kgs. Its more a case of how far do you want to go. Getting the car to weigh under a ton is definatly possible but will cost a fortune I reckon. Its similar to tuning an engine. How much practicality do you want to loose to gain the last hp or get rid of the last kg?
 
Ditch weight OR keep it/put it low down ...

There are diminishing returns and effort but certainly reducing weight by getting rid of unecessary trim and bulky things like OEM seats is a quick win ... I would set yourself a BHP/TON ratio and aim for that with weight reduction and engine mods rather than simply say 300 HP. Unless you are saying 300 BHP/TON ? i.e. 300 hp at 1050 kg - cause that's quite a bit for a road car :-)

Not only how much weight to lose but also where it's lost. Engine covers, glass and tailgate weight loss are beneficial from the perspective of taking the weight from up top. With that in mind you could get a carbon roof made up. This is all fantasy land talk though because costs are what constrains every project!!

Some more realistic easy wins. Remove CD changer and CD changer base plate. Change steering wheel. Remove driver/passenger airbags. Remove front boot liner. Covert to manual windows.

As Brett says though how far do you want to go. You could bin almost everything from the interior and save loads of weight but then you'd be driving round in a hot, loud, tinny, box!!
