Vents - Saxperience

deano_123 · 9th October 2015, 14:00

Finally took the Saxo for a drive today, first time in like 3 years? With the lack of blowers/ matrix and amount of carbon/ plexiglass on the car it gets pretty hot pretty quick inside.

What options do I have on vents? I was thinking a couple naca's in the side windows with ducting but not sure how beneficial these will be?

Could do and see if you can get some cylindrical dash vents to direct the flow or see if you can find a roof vent like on the clio cup race cars.

I'm not cutting my carbon roof so a roof vent is a no go.

Dash vents, where do I route the air from as I have no blowers etc

Is it a pure track car or a road car?

If its garaged then I'd just cut some holes to vent hot air out of the rear quarter windows.

deano_123 · 12th October 2015, 14:00

Think I'll try a couple of these in the rear window

I had naca ducts on mine, with two outlets. Both pointed at the engine but you could use the same and point towards you?

Can just about see them on here

my advice is refit heater system -maybe too hot now --but as soon as it rains it will steam up very badly
the extra weight of the heater system is bugger all for the extra cooling you can get and keeping the windscreen clear and warm on usual uk wet days
minimum would be to fit a heated front screen --about £300 i think --but wouldn,t be my choice--that saps power

I have a heated screen already. The screens fogging is what has put me off just drilling holes in windows as moisture will get in.

Worst case I'll fit a dash top blower for the screen but I'm assured the heated screen should be enough

you will get staming up from your breathing unless you have ventilation .also water being brought into car on your feet or slightly damp clothing ,never mind the sweating you will be doing if your trying --so that is why I would leave std system in --
i take it you have dumped all the glass and window winders --?
if you have not sealed the lexan in -not just rivetted it ,you wil get water ingress + then steaming up if its a wet day without a good flow of air through--for the wirght idf i just keep off the brake longer .LOL or get some more bhp

deano_123 · 15th October 2015, 13:22

Lexan windows are sealed and I have the usual door/ boot rubbers in place however there are plenty of areas where water/ moisture can enter. Think I'll look into a dash mounted heater

Luckily I'm a fair weather person so dont like the rain/ cold/ wet

How much power are we talking about for heated screed drain on engine John ?

KamRacing · 15th October 2015, 17:03

surely not considerably more power drain than the heater blower?

Given I literally have lights, engine, fuel system and digidash that's a lot less than a standard cars draw on the battery so shouldn't be noticeable? Although I am running a lithium battery which just about turns the engine

axsaxoman · 16th October 2015, 08:47

fuse on hrw is usually 30 amp --so must be 15 amps draw -lot more than rest of engine demands all together for sure -- max on engine is usually the fuel pumps --
std car does not draw much in the day time or dry weather --
power steering on a saxo has an 80 amp fuse as well so that could be biggest current draw

never been convinced of the gain from using a very small battery in a "tin top"--and suffering poor starting and extra cost and relaibility issues with fancy batteries
a single seater with no lights no wipers etc --ok - the actual weight percentage differnce on total car weight on a hatchback is very small when its 800 kgs or more--
single seater at 300kgs its bigger percentage difference

deano_123 · 16th October 2015, 10:05

80 mile round trip this morning in the Saxo in the rain to get the digidash calibrated, no issues with using lights/ wipers/ screen whilst sat in traffic. Was quite surprised how well the heated screen cleared the screen when it started to cloud in traffic.

Furthest I drove the thing on a road, my feet are still freezing and I can still hear the fuel pump buzzing in my ears

so basically you need the heated screen on a relay so its off when you apply full throttle

you mean the "freepowr "
we have been selling for the last 8years +
