Air Filter

[Alex B]

?? They made extra HP by removing the filter, does a POD not filter in the same manner as a pannel filter? You would probly find the same improvement if you removed the POD and ran no filtering. That has nothing to do with the air box. ANd has nothing to do with pod filters.

It would be a different story on a 4 litre turbo compared to a 1600 non turbo

Have you ever looked inside the likes of a HKS pod ? The secret to its power is the bellmouth inside. It smooths the air out as it enters the intake pipe. This allows for more air to flow thru & faster. It works the same was as the intake trumpets you see on race engines & 20v ITB's etc. Its quite a sciene to working it out, I think they call it fluid dynamics or something like that.

I was just reading an article in the lates zoom magazine on tuning a Falcon XR6 turbo. They were doing dyno runs after doing the mods like exhaust only(245kW), the adding a piggyback ecu etc. They managed to get 308kW at the wheels. Standard was just over 200kW(The factory rating is only 195kW) Then for a laugh they did a run with the factory air box open so it didn't have to breath through the filter & they got 320kW Thats an extra 12kW at the wheels just by removing the restrictive factory air box set up! You can pick this mag up from most bookshops etc & read it for your self if you dont believe me.

turbo cars indution systems are setup very diferent to N/A ones
if you dont know this then you have no hope of knowing why

Okay, Helmholtz calcs are fully dependant on BSFC. Change the efficiency of the engine, or attempt to pack more air into the engine and the entire intake trumpet length and airbox volumes change. Its surprising that they only got a 5% gain in top end, I would have expected more.

Still you and I both know that a peak figure is pretty much usless as a measure of performance.

Yes but they still work on the basic same principle, the more air you can get in the the combustion chamber the the better it combust.

no point beating a dead horse
you have no idea and no intrest in finding out why
