Which intake fits my requirements?
 

Yes, I know they don't make any power once tuned compared to stock. However, I want to clean up the engine bay.


Requirements:


1. Doesn't interfere with oil cooler lines (I'll be using the Jackson Racing setup).
2. Don't have to remove the bumper once per year to clean the filter.


Thoughts?

I have installed a mishimoto intake which iirc has a 4" filter without removing the bumper. I also have installed a number of FI intakes without removing the bumper. You can remove the T bar behind the radiator which is 2 bottom bolts, 2 top, and 2 that are tight to get tin in front of the bumper (accessible via a wrench) and then you can tug the bumper slightly and get just about anything in there.

So basically any of the intakes work. Personally I don't like the injen intake as it has a lot of turbulence. Grimmspeed, mishimoto, and perrin have the least turbulence in the order i typed listed.

My Grimmspeed was that good, eh?

It's my understanding the GRimmspeed needs to have the box dented to not rub on the lines. Otherwise that's what I would have liked to purchase.

The Grimmspeed is the only one of the three listed that actually has an airbox, and yes, one member did have to dent the box in slightly to not interfere with his oil cooler.

You don't by chance have a link to the thread? Or what oil cooler he was using (or does it even matter?)

What about just running an aftermarket inlet tube (without sound generator tubes) on the stock airbox? That cleans up the engine bay as much as the Grimspeed intake does.

for what it's worth, I have the G/S intake and OEM oil cooler.. I know, doesn't help at all in your case. ha. Clearance of the airbox is akin to stock; if you can get the JROC's fittings to rotate away from the box a little, it would probably be okay

Your link was a follow-up to that later on. There's good technical detail in both threads but photos in my link :)

Also @wparsons I disagree that just a pipe cleans up the engine bay as much as a full intake. You don't even need a pipe to delete the sound generator - I did that almost the first weekend I had the car. Then, later on I got the Mishimoto pipe. The difference between that and the GS in substantial because the stock airbox is enormous in the engine bay. I mean, look at this difference:

plus that sexy wrinkle-coated METAL intake tube... :wub:

*throws cash- no gains? no care*

^Precisely.


There is also the big resonant chamber connected to the stock airbox as well. Thanks for the links gents!

GS has proven gains - read their development thread. It's one of the most well documented product developments in the history of the internet (I'm not exaggerating).

Further, there is no heatsoak. The logs from my OFT prove as much. The velocity of the incoming air is such that heat doesn't transfer all that effectively. I've been hearing the concern about intake heatsoak for over 10 years and I've never seen it actually demonstrated with data.

brother... I made a custom tune for the OFT v2.06 map for the G/S Intake and OFH. 4 revisions of the MAF scale, countless logs and tune tweaks.. I know a little about the intake :). I don't know what you mean by doesn't heatsoak, it's very efficient but heatsoak does happen. It is mitigated by the aluminum box and flow design... but it does happen.

In traffic all intakes IAT will rise, nothing helps against that except for heat shielding, and even then it's not uncommon for intakes (this one included) to surpass 100-120F in traffic, depending on ambient temps.

I can also help you re-scale your MAF (yes, the factory MAF location is designed into the G/S Intake, but trust me.. the stock box is far from this one) if you want. Just let me know... love my setup, but I'm going to underline that the stock airbox is NOT restrictive, so in my mind, no gains. A tuned stock airbox with a high-flow filter will be within 1-2WHP of this G/S box... sooooo.... unless your butt dyno is calibrated better than a MaHa, it's a wasted $300-400 bucks if someone's trying to budget build for power.

Ok, I misinterpreted your post. That's on me.

To clarify what I was talking about with regard to heatsoaking...In my experience, and this goes back to the GTO community I was a part of from 04-08, when car kids argue about heatsoaking on intakes it tends to refer to increasing IATs as a result of the box itself getting hot - i.e. a metal box transfers more heat into the air and thus will be hotter. Which is nonsense, as experience with tuning and monitoring bear out. Yes, IATs will definitely be high in traffic. With any intake, including stock, no matter what it's made out of or how well it's insulated. But as soon as you're moving, it'll drop back down to very close to ambient. Again, that's with any intake.

And yeah, WRT your tune, I have noticed that from the OTS Grimmspeed Stage 1 tune I could stand to do a little work on the tune as my LTFTs never get down below about 3-5% but it's been so bloody cold lately I haven't messed with it. I'm not going to tune for the 60 days a year of solid below zero temps, know what I mean? That said, IAM is always at 1.00 and I never have any knock, but it could definitely be a little better as the LTFTs show.
