Question for you guys: Have any of you ever tried to put a Ram Air system in your Rolla? I found a set up that I like. I was thinkin of fabricatin the box and puttin where the batt goes. I have already relocated the battery to the trunk. Do y'all think there would be any kind of noticable gains with a ram air. Not HP, well HP and MPG?
That's a much better alternative to an open SRI, and I was considering making a perspex airbox or heat-shield like that a little while ago on my 7th Gen, but in the end I decided just to go for a CAI. A CAI is less restrictive and less susceptible to heat-soak, although the length of the piping means you lose a tiny bit of low end response, but easily make it back in the middle to high end of the rev range. Also, in my opinion, a scoop to one side of the hood looks silly. A subtle hood vent might be more appropriate.
As for the MPG and HP from the SRIs you posted above, colder air causes the engine to use more fuel, and warmer air causes it to use less. So you'd more than likely use less fuel with a SRI compared to a CAI, but you'll make more power with a CAI compared to an SRI. With the ram air hood scoop, the air will be around the same temp as a CAI. It depends on what you want more - Better performance or better fuel mileage . Although if you drive it 'normally' then you won't notice a decrease in mileage at all.

Ah, Thats a good point. A little scoop to the side will look silly. I've never heard of heat-soak (course I'm a newb thou). I was reading some posts on hear where a few of y'all, I do believe you chimmed in a time or two, about the pros and cons to a SRI and CAI. There was talk about water lock from a CAI. But then found out bout the AEM air bypass valve. Didn't even know there was one out there. Also actuall ram-air's help out in the bottom end. the faster the car goes, the more air. I dunno, I think what I'm gunna go with is a Ram Air. You're right bout the same temp as the CAI would pull. I just dont like the idea of the filter bein right there by the wheel. I dont have the fender liners. (Got ripped off by the previous owner.) It seems to be such a hassle to have to take the front bumper off every time you have to recharge the filter. I know you dont have to at every oil change, I'm just sayin. The input is great. Hope to hear more. I will, next payday, get the materials for the box. I'll prolly fab it in about two weeks, and post the results and pics.
Yeah hydrolocking with a CAI is a pretty big misconception by a lot of people. The only way to hydrolock a CAI is if you literally submerge the filter in water. The AEM bypass valves don't do much, and are mainly there for peace of mind. As for changing the filter, it's as simple as removing the splash trays and undoing the clamp. Good to hear you've made a decision though, the ram air should do just as good a job. Keep us updated on your progress

Most def will. BTW, did you have to do any minor/major fabs to get those spinter seats to fit in?
Nope, the Sprinter GT seats bolted straight in (not to be confused with a Marino Sprinter). The front seats had the exact same mounting points. I haven't put the rear seats in yet as my Corolla has fixed rear seats whereas the Sprinter has folding rear seats, so it requires welding some latches/brackets in, but the front seats were a piece of cake. It was the easiest mod I've done on my Corolla so far

Awesome!! Got a junkyard here with a lot of rollas. ranging from early '80s to '03 models. Gunna go scavaging in a few days and see what I can come up with. BTW

heatsoak? it happened to me today. i drove 278 miles from Pa to MD and back to PA and on the way home i got caught in traffic a few times and my intake didnt like it too much cause as soon as i crossed into pa i felt timing being pulled and a noticeable power drop. i got home, opened my hood and touched my filter and it was scorching. SRI is just for sound.

+1. When I was running a SRI on my 7th Gen, the pipe and filter used to get extremely hot. Now that I've got the CAI installed, the filter is literally ice cold and the piping is cool to the touch. I completely agree with you when you say that SRI's are only for sound. The CAI is still loud, except it's louder to outside pedestrians than it is inside the cabin like a SRI. As for the heat-soak, even shielded SRI's are vulnerable, but the ram air he wants to go for should help with that due to the vent in the hood (except when idling in traffic like what happened in your case). I'd never go back to an SRI again.

Well sh!t. Seeing how I do a lot of traveling to Austin on the weekends and sometimes during the week, I always get caught up in traffic. Here at Hood, as soon as its 4:45 its like hell gettin outta the gate to get home. Traffic is back up for miles. So I guess its a no-go for the SRI.
Also I was wondering, seeing how there isnt a manufacturer out there that makes a CAI for the 8th, but for the 9th Gen and it doesn't look like Toyota made any big changes under the hood, is it not possible to use the 9th Gen CAI for the 8th? I guess I could always buy it and find out. I dont mind a little fabrication. I tend to take care of the things I really put work into, but that goes for everybody, huh?
I do like the sound of the SRI.
Oreilly's has those DIY kits. The fittings seem to be that ABS plastic. Not to fond of that stuff. Correct me if I'm wrong; ABS plastic would get hot quicker than stainless steel, right?
Before I do all that work for the SRI, I'm gunna try the CAI first. Please let me know y'alls input about the 9th Gen CAI working in the 8th Gen.
The 9th Gen Corolla CAI should work if you cover the MAF sensor hole and drill a hole for the IAT sensor instead, but I can't say for sure since I've never tried it. Hopefully someone else will have a concrete answer. You could always just make your own CAI instead like I did. All you need is a couple of intercooler pipes, a hacksaw, some silicone joiners and a bit of patience . That way you can decide the thickness of the piping and also which route it takes. Plus you get a greater sense of accomplishment when you finish the job, and earn the right to call it "custom"

Actually a buddy of mine here has done exactly that. It worked perfect. All he had to do is make the hole to the outside a little bit bigger. Weld a cover over the MAF sensor and has you eve said, drill a hole for the IAT sensor. Just to make it more snugg, he put a bushin in the hole. PERFECT
Although, I would have to say that I like your idea a whole lot better.
Yep, here's some pics. Although I have a different engine since my is a 7th Gen, so the route and bends in the piping will be different, but the concept is relatively the same:
