K&N Typhoon Intake Review - now with added Pics and Video!

I'm not pulling a Stillen, but I said I'd have the pics posted in a few days, but I'll have to get them all posted tomorrow. I DID take pics, though!

I just wanted to apologize for anyone that is checking this thread to see my insulation and weatherstripping to plan out their own. :laugh:
 
Great, thanks for the sound video



I should be able to oblige in a week or two :D

The good old stillen 1-2 week line eh? I see what you did there.. .:rofl::D:rofl:

UPDATE - PICS GALORE ADDED! See notes above each pic for information if/when applicable.

Insulation Wrap (Bottom)



Insulation Wrap (Complete)



Metallic Fleck Intake Tubing Paint



Intakes Installed



Extended Weatherstripping - You'll notice some "indentation" on the weather stripping. This is where it meets the hood's bulge, so this DOES partially seal with the hood after all!



Filling Heatshield Gaps - I placed as much weather stripping around the area to fill in gaps where hot air definitely would flow in.



Pic of Insulation Installed - These DO make a MASSIVE different in temperatures. When the car is sitting a long time and everything heat soaks, that can't be helped. However, even in 90+ degree weather driving 50+ miles, I can open my hood and touch the inside of the heatshield and it is ambient temperature while the other side where the insulation is has massive heat waves hitting it and the insulation itself is warmer (but obviously not hot or it wouldn't be doing it's job).



Big Gaps On Bottom - These gaps CAN be filled with stuff if one so-desires, but the weird shape means coming up with something weird and jenky (jenkier?) looking...



Backside Insulation



Strut Tower Brace Weatherstrip - This looks by far the stupidest, but it does help close the gap...



Strut Tower Brace Weatherstrip - So I took my stupidest idea and did it on the other side, too...



REVIEW:

After nearly 300 miles on the K&N Typhoon intake system, I have generally positive things to say. First, after my modifications to it, I essentially have all of the benefits of the intake with nearly none of the heat soak problems. The car remains responsive in even the hottest weather unless it sits in a parking lot for 30 minutes in which everything heat soaks anyway because there is no air flow and the heat will seep into everything.

In terms of power, it's hard to determine the gains from the good ol' butt dyno. It seems that if one wishes to get more power out of the Stinger GT, it is smarter to look first at the exhaust system and the tuning. This bodes well for the stock intake design, and I reckon many of you can simply get away with never installing an intake and barely notice the difference in power. This may partially be attributed to the filters being rather small: their surface area doesn't seem to add a whole lot. But then again you'd miss the best part...

This intake simply sounds like nothing I would have ever expected. There's no denying that you will scare Burger-King-parking-lot-burnout-donut-speed-racer Joe. He won't race you, because you toss some 4k revs and he's foolish enough to think that whooshing sound is the sound of 600HP. You will love the WOT sound because you think that there weren't any tiny animals on the road in front of you, but they're actually all trapped in your intake. You'll be scared to go half throttle, because that's when the cops look at you and think about all the possible fix-it tickets they could be writing you to make their day interesting. You will love the sound of this intake, period.
The installation itself is relatively straightforward. As mentioned above, keep an eye on that fitting because it affects your ISG (and your gas mileage), and also in a post, the driver's side intake box DOES touch some AC lines. If you insulate your box, you'll have less worry as the AC lines are ALSO insulated, so two padded things rubbing each other shouldn't cause any immediate concern. I will, of course, keep an eye on it regularly. Otherwise, everything is as expected from the instruction guide.

My final take on this is that you will need an intake eventually when/if you are seeking absolutely all the power you can get. If you pick this intake, you won't be disappointed by the sound at all whatsoever, it looks different if you're into being unique, but you may not really notice gains until other mods are making better use of it. If you're looking at your first mod, this one shouldn't be it: go for your exhaust first. ;)

Since I did a resonators delete on the weekend, having the K&N Typhoon just makes my smile bigger.
 
Zyro, thanks for the great review and follow-ups for the CAI. Extremely helpful. I noticed a really big difference between the two mic location of engine bay and headrest. Could you do a quick recording of the CAI sound outside the car, but not inside the engine bay? Maybe one 6ft-10ft away on a stand, or even from the inside of another car?

Unfortunately, anything outside the car is going to be filled with wind noise with something like a lavalier mic. I might not be able to oblige on this one, but then again, it's not hard to imagine it sounding something halfway between the two because that's exactly what it's like when you have your windows rolled down, lol :laugh:

Bump to alert subscribers that the original post has been modified to put all of the info in one place.
 
does the heat shielding have an adhesive? also, where did you get it? a Lowes/home depot type place?

May need to do something like this. Here in Texas, the heat has been ugly.

Thanks, man! I wish we had infinite editing time on the posts, though :laugh:

No, the heat shield is just sheet metal. The insulation I used is pretty standard stuff you can buy at just about any home hardware store. As for fastening it, I used heat reflective tape in which I circled it and folded it onto itself to make it "double-sided".

Hope that helps! :thumbup:
 
I have been running the K&N intake since about 500 miles and agree with everything the OP says. If you are thinking of getting BOV's, save your money and get an intake instead. You will find you do not need aftermarket BOV's.
 
HI, Is there a chance to launch ISG again after K&N intake installation ? - in my car after K&N mod (without any other changes) ISG not working :(

Yes it will work, you just put the wrong part on. In my picture you just need to replace that with the smaller one. The clamp is going to be too big so I recommend picking up a worm gear hose clamp and your set.

I ve changed original clamp for smaller one and it is tightened strong.

If you using the smaller adapter still hasn't fixed it for you, there are two possibilities left causing you to still have too much airflow through that hose:

1) Air is leaking around the thread or between the hose and fittings. These plastic nylon fittings are garbage to me, but against aluminum they are a must. If you use a stainless steel fitting, you'll shred up the threads of the aluminum intake piping which is the greater, hard-to-repair evil. I recommend checking for a leak around the threads.
2) You still have to restrict more airflow. I think you might have misunderstood my post about it: I tightened the hose clamp ON THE HOSE itself, not at the fitting, to test if it was affecting ISG. Put your hose clamp, say, 1" after the barb and tighten it down until you are restricting the hose more (not completely, obviously). If your ISG starts working again, you have your answer.

Hope that helps!

It's crazy you were able to come up with a better design than K&N and their 100s of staff (guessing) and millions of dollars.

Question: The paint on the tubing, is it specifically designed to ward off heat transfer or just to gussy things up?

A bit of both. Any "reflective" looking paint with those sparkly metal flecks can inherently reflect some amount of heat. If you took a piece of aluminum, beamed a heat lamp at it, and measured the temp behind it, and then took another piece of aluminum, polished it to a mirror-like shine, and measure the temp behind it again, you'd find that the polished one reflects more heat. However, it's also for looks: there's really no reason to paint the pipes because heat soak happens to them regardless of what you do. Making it reflective only reduces the rate of heatsoak, but does not eliminate it. This is because there is also convective heat being absorbed by the type of material through the surrounding air, and metals are great at storing this type of heat.

Long story short: under the hood there is both convective and radiant heat. Reflective surfaces resist radiant heat (think of sunlight); insulation (or air gaps) resist convective heat. My insulation has both. ;)
