All of the ones made from the original mould were wonky, it took me hours to sort it out..i have not seen one yet which looks correct.

Are you referring to the coupe hardtop and tailgate that Cliffie etc installed, or the Lotus S2 cup roof, or the new mouldings currently on eBay that are referenced above?

The cliffie style is slightly off.

The original carbon version which mike had was wonky, it was used to take a mould. So all hardtops (not coupe) are the same.

Ive just checked that ebay link and that also has a wonky intake scoop. Just buy one and spend a couple hours cutting and shutting it..

Hmmm. I've been having a look in my engine bay and cabin this afternoon and I'm not sure my plan is going to work due to lack of space.

 

I was hoping to use the roof to feed air to the back of the cabin, where I would then make a sideways g/f join to the back of the inlet (on the inside of the roof). Thus inlet air could be fed down behind the drivers seat/headrest to behind the drivers back and then through the firewall with a flexi pipe to the turbo. I think that would be doable, but fitting adequate air filter(s) in there somewhere will be very hard indeed. Ideally I'd want 2 flat panel filters.

 

Also there is the issue of driving in the rain, as obviously the filter must never get wet or it would disintegrate and be sucked into the engine!

 

Lastly there is the issue how to fit the roof securely to the windscreen and roll hoop. Bearing in mind how much lift it would give this would need to be a very serious fitment so it never ever comes off when moving.

 

Gonna ring up the g/f master on here tonight to have a chat about it, but if anyone has any bright ideas I am all ears...

Why build it into the roof. What about a 340R style snorkel if youre wanting air.

[CocoPops]

Like so: https://www.reverie...._code=R01SB0046 You could make one into a spare boot lid. Then you could switch bootlids if you wanted to go without, or if risk of rain.

It would work, but even I think it looks "a bit" hideous!

(Tongue firmly in cheek) Thought you didnt care what your car looks like? But seriously, function over form?

It's not that I don't care what my car looks like, more that I prioritise function and looks are more secondary. There are limits though, that Lotus scoop really does look like a tacky afterthought, or maybe it's a deliberate "look at me" statement.

Had a chat with the glass fiber master (AKA Matt Grist) tonight, he came up with 1 very good idea and led me through some other ideas that I had.

The steinmetz funster wins the price in my ugly book.

 

I actually like the 340 scoop, and had bought a few boot lids to give it a try.

I forgot I am not good with fibreglass it seems, so they collect dust in my attic.

Once day though..... one day.

Thanks Tibby.

Hmmm, I'm in a quandary now, so many ways of approaching this. Also, without actually seeing the roof before buying it is hard to envisage what it would look like (internally and externally) and how easy it would be for me to convert to then pass air down into my engine bay.

 

Also, I am concerned about the thing staying on the car at high speed. I can only imagine there must be a lot of lift pulling it upwards and if it came off it could be an extremely dangerous hazard to anyone behind. I have an idea of how I'd make my own fixings, but some of the roofs come with fixings already and I wonder if/what they've been genuinely tested to.

Perhaps a naca duct into a 'normal' roof and piping the air through the bulkhead that way?

 

5 o'clock had one on his race car.

I love the back end of that, shame about the dodgy wider arches.
