more progress and rear exhaust design! following on
daniel mason - 22/1/11 at 09:24 PM

following on from my rear exhaust thread, please take a look in my blog and look at my design idea. i think am going to go ahead with it,but wanted some opinions first. i know i need some heat shields making, and some mods to bodywork to prevent damage from the heat!
blog underneath!

is that the fuel tank?

Its different, i'll give you that!


mistergrumpy - 22/1/11 at 09:42 PM

I can't get orientated with the first 2 pictures. Am I right in thinking the exhaust comes up through the floor behind the drivers seat and then through the rear bulkhead panel?

Then up over the fuel tank


daniel mason - 22/1/11 at 09:50 PM

thats right. i wanted the silencer as far away from my ear as possible, and as the bore is 63mm there is no room for it anywhere else! i put a thread regarding exhaust gasses and safety yesterday and the general outcome was go for it. so i am!


daniel mason - 22/1/11 at 09:59 PM

something like this


mistergrumpy - 22/1/11 at 10:03 PM

Yep. Nowt wrong with being different It may get a bit warm behind you though!


daniel mason - 22/1/11 at 10:09 PM

i know! heat wrap and a heatshield there too!


tomgregory2000 - 22/1/11 at 10:09 PM

I fail to see why people are getting woried about an exhaust being close to a fuel tank.

Have a look under most tintops and the exhaust is rather close to the fuel tank


se7en - 22/1/11 at 10:11 PM

Daniel on a different item.

Are your Fog and Reverse lights mounted on the right sides?

AFAIA the Fog should be on the off-side.

Tom


daniel mason - 22/1/11 at 10:18 PM

thats a questioni dont even know the answer too! ^^^
i thought they needed a minimum of 100mm seperation from rear cluster. but not sure if lights sould be on certain side? can anyone clarify this point?
also the pipe is a good 6" away from tank it this situation. a lot further away than it was in the donor s2000

Ditto. I think its a pointless worry. If the fuel lines were tied to the exhaust, id say yes but theyre not.

Good luck anyway. I like things different.


daniel mason - 22/1/11 at 10:40 PM

thanks richard. your build is looking good by the way!

thanks! I didnt think anyone was reading it! I havent had any critiques from L0rd for a while either!!


StrikerChris - 22/1/11 at 11:01 PM

If i remember right the fog light can be anywhere from dead centre to anywhere towards the offside,then all the carp, so far from your other lights etc.dont see a problem with the exhaust either,except you getting hot,alu conducts heat super quick so the heatshields will soon get as hot as the exhaust remember!loudest thing in my car is not the exhaust but the wind,both straight down my ear,and from most passengers arse's tho.


se7en - 22/1/11 at 11:40 PM

Daniel

The information about the Fog Lamp can be found in section 28 of the IVA Manual

"At least one must be on centre line or to offside of vehicle (Min separation distance from stop lamp 100mm)"

daniel mason - 23/1/11 at 11:20 AM

I can't imagine the wind being as loud as the buddyclub mate, and the wind isn't too bad in the Mnr. The ally heatshield will not be touching the exhaust anywhere and I will lag the exhaust in heat wrap and insulate the ally with that heat proof sheet!


MakeEverything - 23/1/11 at 09:51 PM

Any progress Dan? Im really interested to see the finished prototype and hear it running.


RichardK - 23/1/11 at 10:19 PM

Ok, I'm up for being different but to be honest I don't like it, unless I looking at it in some way incorrectly.



So is that the exhaust exit above the rear arch?

Usually exhausts are pointing out and down towards the road/kerb not at toddlers heads and pushchair height.

If its a track car then cool If a road car then I'm not a fan. Soz mate.

Cheers

Rich


daniel mason - 23/1/11 at 10:35 PM

it is an angled pipe mate and does point down. although not as much as a standsrd kit type silencer. no progress today but next week i will hopefully have it cut to correct length ready for welding!


adithorp - 23/1/11 at 10:38 PM

Couple of comments...

Looks like you're bringing it up through the floor? Won't that mean it's very close to the ground?

Rear fog needs to be moved to the other side as others have said. The lamp also needs to be mounted so the lens is vertical (not just close to). Don't take this the wrong way but... I'd suggest that reading the relevant bits of the manual before bolting parts on, can save a lot of "redoing" and retest fees later.


RichardK - 23/1/11 at 10:38 PM

If it turns the gases to the rear then cool but still slightly concerned about the height of the gases.

Cheers

Its no worse than some buses ive seen.


daniel mason - 23/1/11 at 11:05 PM

i'll switch the fog and reverse light around in the week. and try to get it as close to vertical as possible.


Davey D - 24/1/11 at 10:34 AM

Got to say i really dont like the look of the exhaust coming out like that. Once the car is up and running the whole area around the arches is going to look a dirty sooty mess with all the exhaust gasses blowing out onto them

Exhausts under tintops tend to have pretty good air flow over them so they may not nessecerally (sp?) get as hot as the op's. I think it should be ok though


RazMan - 24/1/11 at 12:30 PM

Quite ingenious and innovative, but I'm not keen on the concept ..... sorry but something more conventional would look much better imo


blakep82 - 24/1/11 at 12:33 PM

i like it very much! good to see something different being done

as for fuel, liquid fuel isn't flammable, its the vapours, so the tank should be fine, don't think the exhaust will be hot enought to burn petrol anyway. think it needs a spark or flame to get going.

as for the height, if you're driving along the street, and a babys parents are silly enough to be that close to the road, who's fault is that? besides you're only 1 car.

i like it!


daniel mason - 24/1/11 at 05:47 PM

thanks blake. i will make it as safe as humanly possible and protect everything with aluminium. also if i angle the tail pipe backwards then the arch might escape from getting sooted up from the gasses. quite a lot of motorbikes have silencers which are under the seat and mine will be way lower than that! cheers for the help everyone!


bassett - 24/1/11 at 08:10 PM

I like it and think the whole idea is cool just hope you dont have trouble with the iva inspector as they seem to always find something wrong, more so when its different.


blakep82 - 24/1/11 at 08:14 PM

seen photos of the fuel filler and carbon look plate, don't like that unfortunately, aluminium would look better i think, but then i really do hold a hatred for carbon fibre look stuff, if its not real carbon fibre


daniel mason - 24/1/11 at 08:42 PM

i know. i made a wrong purchase with a plastic filler cap and thought 'well ive paid for it so i maight as well fit it'
unfortunately it didnt look good and the hole was too big for the ally aero one. you live and learn i suppose, but its not too bad in the flesh and i am replacing it with real c/f soon! it was a spare off cut i had from the reaer bulkhead pannel.
'basset' i will be using the mnr silencer for iva with cat for emissions and db then re-installing this after iva. i need it on though as i will be having a mapping session done in the next 6 weeks or so!


scootz - 24/1/11 at 08:48 PM

It's different... so I like it!

Hope it works out in practice!


MakeEverything - 16/2/11 at 06:37 PM

So How did it go??


daniel mason - 17/2/11 at 10:52 PM

Am gonna get it made up
asap as I've got the ally heatshield made up and ready to fix this weekend
