So all ive got performance wise is a K&N filter, cat mod and custom exhaust. (So far). When im on the freeway doing like 75ish and punch it my truck seems to just fly and the RPMs are way up there. Now normally my truck craps out past 4 grand or so im guessing cause of the powerband. My question is, am i getting some sort of ram air effect from the speed? My air box lid is open but that really shouldnt make a difference. So whats the deal? Anyone?

I don't think you're getting anything from the lid being open...Mav has a scan gauge and it actually reads 30 degrees hotter with the box lid off...:shrug:

Dunno guy, it's probably the mods + the I5...I know on the freeway with the cat mod, my I4 livens up quite a bit.

Heh.

If you wanna get into the ram air portion of it, try and drill like a 1/2" hole in your box and run a tube into somewhere like your lower valance grill...although other boards say it doesn't help, I beg to differ. ;)

what speeds are you guys traveling at when it craps out @ 4k rpms?

3" tube through the radiator support, down to the valance. leave the stock inlet open and put ur lid back on. it does work son.

This is just my opinion...I don't think the 'ram air' thing everyone is doing is really ram air, its more of a true cold air intake than anything...After all of the bends the air has to make its lost most of its velocy, at that point its being sucked by the engine not pushed by the pressure of the incoming air...I'm not saying it doesn't work, if the air is that much cooler it would make a difference but...its just not ram air :shrug:

:yeahthat:

That's the way I've always felt about it as well. It can help, and may be a worthwhile mod but it's not really 'ram air'. But whatever though, po-tay-toe, po-tah-toe.

ive been all over the "ram air" threads and i will be the first to say the "ram" effect of it is a joke(imo) BUT that mod DOES give you some nice cold air. and keeps engine temps down noticeably. thats why im so pro-"ram air" :)
