Thats looking good Adam.
Keep us informed in your findings witht the temp difference, i have tried some thing like this on the SEAC with a remote digi temp gauge and a sheld made out of cardboard and silver tape.

I`ll keep adding info as i get it...Keep us informed in your findings witht the temp difference, i have tried some thing like this on the SEAC with a remote digi temp gauge and a sheld made out of cardboard and silver tape.

this is made to fit an SX but if you were able to relocate the air filter it would work on any wedge, i`d say it would work better again in the UK as the air temp is lower ( captain obveious) what i mean is the gain would be more, if that makes sence
well I managed to get some heat resistant ducting at a discount rate, and it has improved the air intake temp again, the flow of air has also improved as the old ribed s
t had holes in it and had been crushed by the manditory TVR cable ties.the temp at the filter is about 50% cooler now to what it was, it now avreages 22deg C as speed, it will go up when you stop but is down again within a mile.
it doesn`t seem to restrict the flow of air but i do intend to put a figure on plenum pressure with and without, i`m trying to borrow a boost gauge.....

There is another solution .. at least on the SEACthere is..
The space in the front wing is fully enclosed and can be opened up at the top..
Bit damaged but now fixed..(dont let your wife do donuts at the wedge fest)
Behind the oil breather thing on the wing .. 3 holes for the cool air to get to the air filter..

Looking good there Adam, dose the car feel any different to drive, has it changed the carateristics of the engine or the induction note...
My SEAC has been away for a few weeks getting a new loom installed, new ECU and set up on wasted spark, just got it back on Saturday and ohh my what a difference in the engine burning the fuel correctly, plenty of oomph 320bhp 340ftlb
but with the loss of the flapper there is more induction noise so ill need to think about a heat sheld to help with the soak.
Ill proberly make some think out of cardboard then use it as a templet for fiberglass.
You should look at getting a motor bike MAP sensor and connect it ising a vacum line to see what boost you are getting, im thinking of adding one too my engine even though it N/A as i can watch whats going on through the ECU.
It does look like it belongs in there Adan

It sounds the same, seems to have a bit more oomph, i`m guessing back to how it would be in a cooler climate, i`ll feel more difference once it cools down here...........
What ECU have you fitted Cambelt?
I`m reluctant to loose the flapper as its what makes the wedges sound so good, all the pops and bangs,
I`m wondering if you could leave the flapper there even if it is not in use???????any thoughts anyone????

Adam, i would go with the boost gauge setup like UK Adam's using a gauge and a vacum take off the plenum.
The ECU i went with is the DTA S80 as it has the flexibility i wanted and i can hook up a manifold pressure sensor and look at the results in real time on a laptop.
The wedge noise on wedges with flappers are due to the extra air valve at the rear of the plenum allowing in extra air in through a spring loaded valve when the throtal is closed and the extra air coming in moves the flap which dumps fuel is dumped in and pops in the exhaust.
The EAV can be ajusted to increase or decrease the effect.
This effect can be written into the code but i think the car sound good on lift off.

Pah! Mine was much simpler - a pressure gauge linked to the plenum. No electronics and you can see the boost nicely in the cockpit. I used some plumbing microbore tubing to take the line through the bulkhead. There is a blanked-off vacuum hole in the middle of the plenum.
Yes this has been my intention for a while, a mate has one but I'm still waiting, I think I'll just go get one.... Being a bit time poor isn't helping. Adam is yours a boost gauge or a pressure gauge as the pressure gauges I've seen have too larger increments as it will be I'm thinking around 6 psi?????
I'll have to pop down to
Where did you mount it? Any pics?
Cheers

Well I finally got it all together and working.
I ended up buying a boost gauge and it mounted very nicely where the clock was (never used the clock anyway),I also got the kit with the proper fittings and Adam I did fit it too the blank on the plenum.
The boost is reading around 5.5 to 6 psi with or without the cool air induction but with the cool air induction on it reduces the air temp inside the air filter by 50 % while moving
So all up a success I think, now I just need to tidy it up a bit.

Yeah - sounds about right, and the lower intake temp should make a big difference.
How are you measuring the induction temperature - with a thermocouple? If so, move it to the airstream in the junction between supercharger and plenum - you'll get some pretty interesting results.
Also I notice a big shiney stainless air tube where my old one perished - does that give enough flex when the throttle it blipped and the engine cants over a bit?

mmmmm this has been going on for a while......
another job, jobed...
to help with reducing the air temp and plenum temp i fitted an insulator..........
and the result of that after a short but enthusiastic drive was........
to......
pretty happy with that, it was a 25deg day too.
and with all that im still getting 6psi boost at WOT.
cheers

You shoulda got your g/f to do that mate!!! ;^)
Bump! For Martin...
P.S. What boost do you now get - peak - and at what RPM? Does it start to drop off say at around 4500-5000?
Do you also get the "gulping" effect where the needle vibrates at max throttle?

It holds boost at around 5.5 to just under 6 psi can't say I've noticed it drop off....or vibrate usually I run out of road first and the freeways are full of cops.
My mate said he will bring over the mould, Adam he is staying in Linton and Cambridge that's not too far from you is it?
Even non sx's could use it if they just relocate there air filter...
Anyway give it a go.

Adam,
Your work is first class.
I was looking at having a couple of these blended in to the front wings and vent some of the heat out this way>

Change the script as well of course and have these super bright indicators into the bargain.
