On God!

[h2s]

have a look at this.

Blitz Sus +13.9bhp increase

HKS Mega Flow +13bhp increase

Apexi Power Intake +14bhp increase

K & N Filtercharger +13bhp increase

I mean come on! It might be around 4-5 max with an accomodating exhaust or a full induction kit, but not on its own !

[Moffmo]

thats the offical figures they use to attract max muppets

[Robie]

That is the figures they get on say 1000 BHP dodge vipers ;)

[LORD_ED]

correct e if im worng but if more dirt is getting thru that means more air is getting thru that should mean higher bhp gains so the apex should be the lowest bhp???

if im worng tell me

also the results are from a supra that explian claims

[Robie]

Dirt is larger molecules than air and if you bring alot of dirt through the filter surely it will lower the bhp as the air is less clean which is the purpose of an air filter after all.

[h2s]

if more dirt particles pass through, getting stuck in the filter, that reduces the area for the air to flow, thus reducing power.

That artical is for Supra's! ;)

And if a 300ps Supra gains 13bhp a 1.0 yaris wont .. and remember that the supra is turbo'ed and turbo'ed car make a LOT of gain with exhaust/filter where NA's don't.

on the first page ..

All filters were tested on a modified (300ps) JZA70 Toyota Supra for power gains.

and I had a HKS filter on my car, and there was dust in the intake when I took it off .. this dust then goes through my turbo, into the engine and out the exhaust, wearing down the metal on it's journey.

I'm now running Apex and have no such issues.

Yea, they're talking about Skyline mods, so do the math and it'll average down for ours to 4 or5 hp...

cheers

so do the math and it'll average down for ours to 4 or5 hp...

And thats if ur lucky!

[Yarisboy]

2hp is more like it

[Moffmo]

2hp is more like it

yeah, more like 2hp of response....

at the end of the day all you're going to notice is a decent induction noise on a car that can't back it up. :)
