Hey guys we’ve got this new product i think you’d be interested in. So basically its a velocity staack for the end of a 3" intake that increases flow into the engine.
We tested one on the roadster and here is a before and after dyno:
They use a 6" filter and the stack obviously connects to a 3" intake.
We’re thinking about doing a group buy and would like to use this thread to gauge intrest. The flow stack itself would be like 45ish dollars and we can also supply a filter or you can get your own.
turbo cars will see it more as increased compressor efficiency, as the inlet pressure on the turbo will now be higher, the difference between inlet and outlet pressures are smaller, thus the temperature gain is smaller
intake air temps will therefore be lower. also in theory the turbo would spool faster, however it would be hard to notice in real life
im just wondering how fitmint of a 6" filter would be in my s13… sometimes ive seen all guys can fit are those dinky lil HKS bowl shaped filters… i could fit it with a small downpipe so it dosent get crushed by the hood.
not really meaning to hijack but…
this is a z32 MAF install. i think its the same concept in some ways… and i think its a 6" filter base, might be a similer to this in the aftermath. but fitment is tight.
ok so they only make a 3" stack right now but are bringing out a 3.5" version soon. So if you have a 4" inlet on your turbo it will not work for you, sorry!
The previous tests were with a standard 3" K&N filter
The overall diameter of the filter is less than 7 inches, which I would imagine is about the same as a HKS Mushroom filter. The filter is not as large as you would imagine, and will fit in most circumstances
um… wow… comp. eff. is based on the shape of the compressor impeller and rotation speed of the compressor impeller… any gains in flow eff. would be measured in .001 bar range… and the first bend in the CAI to the compressor inlet negates any gain potential by a factor of 10… you have better gains in flow by using more advance compressor housings then any other ‘cold air’ side add on.
and there are many companies out there with ‘horn’ entrance profiles, HKS, Apexi, Blitz, tonnes of ebay knock offs even.
