probably trying to over engineer something that isnt really needed to be honest but i thought i would ask the question.

just reading the latest issue of trackdriver and noticed there is an rx7 mark 1 who are making a airbox out of nimbus:



would this be worthwhile? i got tonnes of nimbus left over so was thinking might aswell use it if it could be seen as an advantage. i imagine it would stop sucking any hot air from the engine into the air filter. However will this restrict cool air into the engine bay causing higher engine temps?

what ya lot thinking

[slindborg]

I'd leave it be. Seems that most of the S/C lot are doing fine with whatever setup they have, so to stop cool air entering the bay would be a bad idea

[The Batman]

true true mr borg, or how about just creating a side as such around the airfilter so air is forced into the box but as the filter doesnt take up the whole ear the top and bottom can be left to cool the engine down? or should i just f off and get outside and work on the car and tell my procrastinating head to shut the fcuk up about trying to add more to my list

GTF outside and work on the car

im off anyone want any nimbus

Who has been reading the dictionary? And the answer is yes! Get the fookin car going first!

Oi... Get the fcuk outside... Deliberation and distraction is invariably costing you time and money.

futurama isnt over for another 15 mins

so is this still a bad idea?

[slindborg]

so is this still a bad idea?

Its about as good an idea as fitting Tb's to a long stroke engine

[The Batman]

I forgot about this, so still a bad idea? But what you are saying mr Borg is the airbox (itbs) would be crap on a standard engine but on modified engine it could be a good idea

[techieboy]

The incoming air comes through the ear and what's the first thing it hits? Yep, your air filter. It's not like the filter is stuck in the middle of the engine bay of a FWD car out of the direct flow of incoming air and therefore needs shielding from heat. Haven't you got more important things to be doing on the car?

[The Batman]

I was just thinking one Half of the filter will get cold sir straight from the ear whereas the other side might get warm air coming from the engine bay was just thinking that a deflected plate would keep it so all air available to the filter would be cold air Yes I have got more important things actually 33 things on my list but what's one more...

[techieboy]

It would only have any effect if the car was stationary. When the air is coming in at any speed it'll still be cool air that flows around the filter that would be drawn in by the other half of the filter. You'd be better off making some form of deflector to route the air from the offside ear to somewhere more useful than just flowing straight back to the rear of the clam. Might be helpful to divert it towards the exhaust manifold and downpipe for example.

Plus adding the nimbus for NO good reason will add weight and gain you nothing..... eg you will make your car slower

Joe, if you want to free up some space behind the turbo ear it's possible to move the airbox up and closer into the engine bay. If you have a look on my website you can see that I did this so that I have space for a massive oil cooler in the future if I need it. I had to cut the OEM plastic box up a bit to fit, but it went into the space under the A-frame bar quite well and securely.

[MartinS]

Another possible use would be to form a box around the cone that still directs the air into the cone and engine bay but gives you somewhere to attach sound deadening panels. I've just bought some as I am going to see if adding these around the airbox area or under the engine lid, may in some way, absorb some of the high pitch sound of the sc that is causing probs with noise at some tracks.

I've always wondered where the induction noise actually emanates from. Especially with the S/C attached too. Would a short pipe to the filter inside a nimbus surround then a long cold feed from the ear be better.

I don't Want to free up any space as I have already eliminated the standard vx oil cooler and fitted a b207 one which is ALOT smaller and lighter

I just wanted to gsrantee cool air but it would appear it is not needed so i will just sell my spare nimbus

I like the whine so I don't really want to eliminate that although you did then you could modify and fit an Lsj air box or I think techie was looking into fitting a turbo one... Not sure what the outcome on that was though
