Christmas Air filter chuckle
Robsparky99 - 15/12/15 at 03:07 PM

If your feeling down and need a little laughter in your life, then have a look at my alternative to a Pipercross sausage filter:















will do for the time being when I attempt to set it up this weekend, fingers crossed.

nice, I made my own cage like that too for my RV8 with Bike Throttle bodies.. it was essentially non blocking as the rolling road proved. As long as you kept a good distance from the top of the trumpets, should be fine in my mind.

A long time ago, I knew a bloke who swore by using old pairs or tights as air filters, stretched over the carb.

His XR2 sounded very rorty as he revved it up in the car park with the bonnet up - right until it inhaled the tights (yep the whole lot) and promptly seized.

I'll never forget his face going from smug satisfaction, to disbelief, then sad realisation....

Last year I was doing similar with a rag cable tied to the single throttle body just to keep crap out while I was moving it in and out of the workshop. Anyway I gave the throttle a stab and it inhaled half the rag which jammed the throttle half open and I nearly put it into the wall before I killed the ignition...

Ran my GT4 for 40K miles with no air filter on it at all. No damage evident in either turbo or bores after stripdown when i finally smashed a ringland through a dodgy timing event!

I ran with no filters for a year.... never had any issues

But your engine WILL have suffered from additional wear because of this. If you get unlucky with a stone, or errant nut/bolt flicked up from the road it becomes a very expensive mistake.

No more than 20 years of abuse and further year of even more abuse in a kitcar would have already done.

We used to run throttle bodies in tintops for years without issues

Yeah to me the risks are fairly low, there will be additional wear from dust but in my view engines are wearing parts and semi disposable, I'm not looking for oem levels of lifespan. In a tin top you have to be quite unlucky to get a rock into your intake. I can't see that being more likely in a kit. The one concern I do have is jamming a throttle but again the likelihood is so tiny I weigh it up like the increased risk of cancer due to eating bacon.

yum bacon!

Exactly

Think the fuel pump may struggle with that!!!

Mr Whippy - 23/12/15 at 12:35 PM

I ran no air filters on my cortina as it was an old engine however I did regret it after finding myself stuck behind a truck carrying sand or something and me in a great big cloud of dust the bores did have a few big scratches after that I can tell you

coyoteboy - 23/12/15 at 12:45 PM

Yeah I think it depends how naturally shielded it is in the car. There's no point trying to run filterless if your cold air intake is pointing forwards in the grille. In my cars they've always been nicely tucked back behind several radiators and bulkheads, or up behind protective plastics.

mcerd1 - 23/12/15 at 01:40 PM

The risks might be low, but I don't consider my engines disposable items so I always run a filter (with the exception of a few times that I've been working on the carb in the workshop for a few min)


Sausage filters aren't cheap, but decent cone style filters can be
and a DIY airbox could be very cheap (unlike the pipercross rip off ones)

an airbox will let you locate the filter in cold air (without sticking through the bonnet) and also reduce the noise which is useful for IVA's or track day limits.
And if really want to you can tune the size of it to smooth out you power curve (lots of trial and error)

Very smart, never seen anything like that before!
