TSP Posted January 19, 2009 Share Posted January 19, 2009 Someone has agreed to make me an ait intake tube for my Starlet but now I've ordered it I'm having concerns! I'm planning on re-locating the filter towards the front of the engine, along side the battery. behind the radiator. I've designed my heat sheild and ram air intake to the filter but I have 2 worries!Is the filter too far away? Would it need to be closer to the throttle body to be beneficial?andThe tube will have a 90 degree bend in it, it'll run from the throttle body across and then bend 90 degrees towards the front of the engine, the worry I have is 90 degrees too sharp? Or will the air find it's way ok despite this?Good thing it's not costing me too much! Thanks Quote Link to post Share on other sites
ste91 Posted January 19, 2009 Share Posted January 19, 2009 If the bend is mandrel bent then it's fine, and the length shouldn't be a problem at all.Putting both of those problems together - look at the standard airbox setup. It's full of bends and the piping (if you were to straighten it all out) is actually quite long. So either way you'll have less overall length and less bends.The biggest problem with open filters like this is heatsoak and getting a decent amount of "cold" air to them, but it looks like you have that sorted. What is the heat shield covering though? Because you will be quite close to 1. the exhaust manifold and 2. the radiator. If the heatshield doesn't completely cover the filter then you might want to get some exhaust wrap on the manifold or something to cut down on heatsoak. Quote Link to post Share on other sites
TSP Posted January 19, 2009 Author Share Posted January 19, 2009 Looks like I might have to re-think this... It's the bend I'm most worried about though. It's not mandrel bent it's rubber hosing from a submarine Quote Link to post Share on other sites
5T4R7ET N/A Posted January 19, 2009 Share Posted January 19, 2009 Have u got any pics of teh proposed setup? Quote Link to post Share on other sites

It's not mandrel bent it's rubber hosing from a submarineAslong as curved and not a square 90 degree bend then it should be fine.The other thing though is it should be a smooth surface, no bumps as they cause restrictions to the airflow.And remember you will need to plug the air temperature sensor in there too (it's easy though, just drill a hole in the pipe, take the rubber bung thing out of the original airbox and cram it in the hole, then stick the sensor in the bung).

Steve GT Posted January 19, 2009 Share Posted January 19, 2009 Would have thought aslong as its near the front of the car it will be loads more beneficial than the backyou'll be geting more cold air than beforeas for the bend.....as stated aslond as its a smooth 90 degree bend the air will find itself easily enoughLittle advice i recieved from toy tuning was when relocating the air filter is use Heat Reflective tape for Inlet Track with this and reducing the intake length with the filter sitting near the front bumper the intake will be mint Quote Link to post Share on other sites
TSP Posted January 19, 2009 Author Share Posted January 19, 2009 Thanks lads, I've edited my plans now... It should work out lovely! Just gotta collect a couple of other bits then I'll crack on and put some pictures up! Quote Link to post Share on other sites
