looking very nice  s:) :) s:)   Are the vents functional at all, in the way that you get extra downforce at speed on the front?

Oh and BTW what spoiler is that, I love it  s:) :) s:)

it's functional to draw some heat from the radiator, but no downforce
to keep the bin, you have to use a black plastic "guide" which forces water away of everything in case of rain, so this prevents any downforce improvement

Rotora
I modified the rudders, because they were too high

you have to host it somewhere, like imageshack

If you can draw some heat from the radiarot through the bonnet, instead of forcing it all under the car, aren't you automatically creating some extra downforce?

Slightly offt track. Just want to share my hood since vented hood is mentioned.

A different take on it.

can you still use the front bin/lid?

Air rushes through the vents to cool the radiator, yes there is downforce. How much I don't know. The heat from the radiator doesn't escape through the vents though due to the rush of cold air coming down from the vents. Instead it dissipates through the front grill. The vents merely helps in the cooling and some added downforce.

NO! YOU CANNOT USE THE FRONT BIN OR EVEN THE LID. YOU LOSE THE SPARE TIRE!  s:cry: :cry: s:cry:  

That's the whole point of vented bonnet. You get it to cool the radiator and provide downforce. If you still use the bin, how else can downforce and cooling come into play?

I'll say get the bonnet, tell the vendor to under declare it on the shipping form, and ship by boat to cut down on S&H and VAT. But pray everyday your bonnet wouldn't get damaged throughout the journey. That's what I did.

The bonnet is not that expensive. It is but not very. 550 quid max including shipping. It's the best looking bonnet I know though.

cheers matey, I dont have a spare anyway as i have Andrews 18" deep dish alloys so a spare would be pointless.

wouldnt want to loose the front bin tho, I was rather hoping that you could just remove the outer plastics to aid air flow and keep the bin/lid for trips away (luggage)

such is life

The thing is Toyota distributed the weight of our 2 with the spare tire in mind. Taking out the bin, lid and tire, you throw off the weight balance of the car. What I intend to do once I get back my 2 is to add a secondary fuel cell and relocate the battery to the front, cut the capacity of the primary fuel cell, to balance the weight out. One needs to be warned of the consequences of locating fuel cell to the front though. In the event of a frontal collisions. its KABOOM!!! But adding a smaller secondary fuel cell that's reinforced and linking it to the primary may be an option one can pursue.

It really is pointless and silly to keep the bin (not that you can), because in the event of a downpour, you might as well keep some goldfish in it.   s:D :D s:D

thats why I referred to the bin and lid   s;) ;) s;)

nice bonnet just not for me unfortunately duwe to the fact that we use the car you go on holiday in so need every bit of luggage space.

fuel cell sounds like a plan, although with the bin in place a secured tool box or the likes does the job just as well

how about some very heavy bracing under the front of the car? surely that will replace the wheel mass?

I think the point is to distribute weight, not adding them.
Title:
Post by: northernalex on November 21, 2006, 15:59
Yes but if you say its a problem with the weight distribution by removing the wheel then replacing exactly the same mass in a very close position, like under the car as bracing should solve the problem?  Moving the mass closer to the ground will also move the centre of gravity downwards slighly increasing stability.

Now we have to ask ourselves what kind of braces are as heavy as the spare tire (11kg) where the weight is concentrated at one particular spot? Since the weight's been taken out, it wouldn't hurt to work with the current weight and try to distribute it. Get it balanced and having weight reduction at the same time is a plus dont you think?   s:D :D s:D  

Your idea of  moving the mass downwards to achieve lower center of gravity is definitely a right idea. The idea of having a secondary fuel cell in place of the spare tire is certainly not new, at least the idea of it is not. The Techno Spirit MR-S in Japan has its fuel cell relocated to the front (though I'm not sure if they relocated the whole of it, or partially). But I figure if you can relocate 1/4 of the fuel cell (equated to 1/4 full tank, that's 9kg), and cutting 9kg from the rear can be an idea worth pondering if you already have put on several kgs at the rear initially though. Or like you said, replacing something close to the weight of the spare tire to it's original place, we can just add the secondary fuel cell to the front, and be done with it, no weight reduction from the rear whatsoever. Making the combined fuel cell 125% of its original capacity.

What do you think Alex?
Title:
Post by: Tem on November 22, 2006, 04:56
About moving the fuel cell from the middle of the car to either end, I'm not sure if that's a good idea. The main idea behind MID-engined car is to get most of the weight in the middle. Moving it away from the middle might not be a good idea, even if it improves the weight distribution measured from the tyres only.

If you already lightened the front, why not lighten the rear (and the middle) as well? Instead of just moving weight around the car, which always tends to add weight too, with new/longer hoses and wiring.

Or try to regain the lost front grip with other things. Like going from 185 to 195, playing with the tyre pressures and alignment. I have 195 up front, with less pressure than the manual says (for 185) and toe out instead of toe in. I don't feel comfortable recommending that to anyone, but I think it's worth a thought and maybe a try if you feel like it.  s8) 8) s8)  I'm sure there are other ways too.

i really like it, the bonnet, and spoiler all work well.

the one minor thing for me is the large single exit exhaust, to finish the car off it would look sweet with a stainless twin, or possibly quad exit exhaust.

H & S make a lovely little system.

to modify your nappy you just cut off the right hand side (as if you were looking at the rear) i think there is a line to follow if you look at the moulding. you basically take the side bit off. you loose the 3rd fixing hole but thats i got the swap over one from which was done by H&S
