Hey all,
This is a topic that hasnt been covered much for the guys upwards of 400kw that I could see.
Here's the issue;
On my GTR i have the ARC airbox with twin genuine ARC filters. Give it a squirt of full throttle and the filter gets sucked in to the actual airbox and all mangled up into a mess ($110 each, this gets tiresome quickly). It was funny the first time, but now its just plain old annoying.
This problem rose its head somewhere between 380 and 403rwkw, so im confident in saying that the limit of the (completely unmodified) ARC box is somewhere in there for at least my setup. Note; ARC dont seem to list a max HP/KW for this box
Now given that im past 403rwkw, something has to happen here as its annoying but not only that im sure its a big restriction on power if its strong enough to suck the filter in (which has allen keys on the filter bracket).
So far ive come up with;
1. Mod the ARC box with more bracing for the filters (not keen on that, its too nice as it is and the restriction will still be there)
2. Get a stock airbox and mod that but who knows how that will turn out
3. Something made from scratch using high flow commodore/falcon filters locally available and with huge surface area and filter braces
4. Use pod filters (no fkn way)
I know this thread wont apply to everyone just like the GT-RS on stroker motor thread, but id love to hear what anyone with a 400kw plus GTR has to say on the topic so please speak up
.....aaaaaaaand go!
