First impressions:
I've driven the car to work today still in its semi-stripped state, just the boot carpet has been put back in.
Bare in mind I've only so far done the tailgate, back panel, arches and rear qtrs with mass loaded sheet and the rear qtrs and tubs have been foam lined. Already...
I didn’t, I just had it in my head it was 12kg.
I looked at so many products, the 12kg must have been another. I’ll accurately weigh a sheet tomorrow and multiply by 30 and let you know.
Thermal insulation isn’t something you really think about in a car but it makes a huge difference. I’m...
Yep that’s correct.
The whole lot will be at least double layered with 1 layer of 1.8mm Hex mat (50-75% coverage) then have at least one layer of 6mm super liner acoustic foam. The foam will be closer to 100% coverage. So far I’ve used 2 full sheets of 2mm Stinger Road Block on the tailgate both...
It saw one race because it was so much faster, Bernie withdrew it. His designs in F1 were ahead of the game, as was his designs in the Mac F1.
Look at all the tech on the F1 back in 1990, that even had Venturi fans to adjust the efficiency of the diffuser. Internet login, 627bhp NA engine...
Well worth getting in and treating the areas behind the filler. Dirt and moisture sits there and has nowhere to go but rot the metalwork.
mine was very light surface rust because it was caught early. It’s now epoxy inside and out.
Fair point, but I still think it will take all of 9 years for someone to better Murrays design and vision.
Hes been designing this for years and only now is it coming to fruition. Other than Neweys Valkerie, i don't think anyone has a chance.
Not much to report at present, got some bits in the pipeline to upgrade the audio in the car to make it better day to day.
So just some pics of the old girl doing her daily duties.
For me its simple, the car was always built as a road car that i take to the track, not a track car i use on the road.
I do 300 miles in it a week, hence why it has a stereo and AC etc. There's nothing this side of £20k id rather drive every day, so the little Clio is staying.
I just see no...
I'm going to focus on the rear and work forward. I don't think there's a great deal in the front of the car that actually required deadening with loaded mass, just more noise suppression. The bits that vibrate are actually in the rear of the car, tailgate, boot floor, wheel arches etc. The rear...
The sound deadening arrived on Saturday. However I'm still collecting parts so i can do all the sound deadening and some small audio upgrades in one hit.
Then its just getting the free time to do it all nicely :)
Hahah, totally not what i meant.
I mean NVH has moved on since then and auto manufactures go to greater cost and better lengths to make a vehicle more refined now than they did 16 years ago. :D
True,
Having said that, they're rattly French tin because they're 16 years old and were built for pennies. I think some significant improvement can be had for a little work without adding a heap of weight. 10-15kg of various materials back in it should make a decent enough change i hope. All...
We discussed the MLV too but decided to see how we get on with the above first. I think 90% of my noise is tailgate/back end from the exhaust anyway, plus tyres.
Engine noise is pretty good.
Okay so I've been talking to the chaps at deadening.co.uk and they have recommended similar to the above.
I explained i wanted to try and make a significant improvement in cabin NVH quality with the least additional weight as possible.
They went through various options of deadening and...
Looks good @robmuns.
what closed cell foam did you use?
I’m suprised to hear you say it’s not night & day, as I’d expect for that amount to see a significant reduction in cabin noise.
I think my main resonance is the tailgate. I’ve tried many things over time to improve it, and each time I have managed to do so, sometimes it would last and other times it would return.
The rest of the car is pretty good to be fair and after having a proper listen last night on my way home...
I agree, i think its a totally psychological thing. Unless you do a radical weight change or significant unsprung change, you wont notice it anyway.
Wheel weights i can feel, my seats i never did notice as you say.
I've dumped some weight with the Pole positions and rear bench so dont mind adding some back in.
I think even if i were to put 20kg in (Which is WAY OTT) the benefits in comfort vs the detriment of weight would be worth it.
Perfect Louis, exactly what im thinking.
Ive been reading that a closed cell foam over the top as a decoupling layer takes it to another level again.
Would you say it was worthwhile doing?
Yes it will be calculated where they can add the least amount of product for the most reduction in NVH.
My car runs no back seats as i just prefer the appearance but all carpet and trim remain. So i was thinking about doing door skins, rear qtrs, full boot and tailgate plus under the rear bench etc.
