I got a K&N drop in filter, and i have heard other people saying thats a good thing to put in there... how much does it actually do for the SVTF? I thought i read almost 7hp... but that just seems crazy.
I got the K&N drop-in. It's not an earth-shattering change, but, it definitely has much, much better air-flow than the paper-filter. If nothing else, your engine is much happier; that makes me a happier owner.
Im thinkin im going to put my stock airbox back in....been hearing it actually works better than a SR for a JRSC. When i had a K&N filter in mine, i noticed a slight difference, not really more powerful but more responsive.
My two cents - I went with the K&N drop in because a few good test out there have shown the stock system to flow sufficiently enough for a naturally aspirated setup. I modified the snorkle tube and the side inlet to the airbox as well - see below. With this, I think the thing is flowing plenty of air for the engine, particularly at speed. I also upgraded the throttle body and went with a Random cat and am working on computer tuning - I have to say that on cool evenings, temps in the high 50s or low 60s lets say, the thing really pulls hard in the mid range - I bet it's a combination of the mods rather than just the intake mods but I like to think the intake mods really help to get cool air in. Actually, I data logged some on it and the intake temps were basically the same or just slightly above ambient temps very quickly after the car started moving.
How would thermal wrap work on a SRI??? If its good at keeping heat in (header) then it should do a good job at keeping heat out, right??? I know it would probably look a bit ugly (although they sell the wrap in black also), but that combined by a little creativity in directing more airflow to the filter and it should be a pretty good setup. Any thoughts???
