Quick question.. highways here are loaded with sandstorms.. you sure it wont be a problem? Also, its illegal to manually wash your car here in public roads (unless you have a garage which I dont) so its 99% pressurized auto car wash.. wont that be a prob?
If both answer to no I'm dayum sold!
cheers,

Just a SWAG, but perhaps the temp drop is due also to improved airflow of this intake? It's been a LONG time since thermodynamics 101 so I may be wrong, but better airflow, a.k.a higher air acceleration, would create lower air temps due to balance of energy.
Any idea how painful this would be to install if you didn't remove the front bumper? I'm not removing the bumper for an intake install, sorry.
Thorough review, looking forward to the JWT one.

How easy is it to get to the filters, for cleaning?
And not to be an ***, but are we looking at the same dyno's? Am I missing something?
Sure, the peak is 11 HP, but throughout the power band, the gains are minimal or you actually lose power. ONLY from 6500-7100 rpm, the gains look to be around 5 HP, and from 7100-7400 rpm the gains are more like 10 HP. But that's it for any real gains.
So all this incredible acceleration I keep hearing about is just in the upper 500 rpm of the powerband, and that's pushing people into their seat?
"Didn't have to downshift once to pass anyone due to the additional kick"
You didn't have to downshift, so you're cruising at, what... 3500rpm? I'm glad those extra 2 HP really helped out...
C'mon.
I'm not being a hater; I'm being realistic. I'm not saying it's a bad product, and I think you'll see bigger gains after a tune. I think the G37 ECU does not respond as well to simple bolt-ons (is more controlling/limiting), and a tune is even more important then ever.

It's a performance product...and the high-end gains are great! and I definitely agree that unless it's not the sound that excites you, this upgrade is more useful with an ECU flash.

I thought you can't add up all the hp of each individual mod and say that is what you gained? (e.g. say 10hp(intake)+8hp(HFC)+10hp(exhaust) wont' equal to 28hp on the dyno.) I don't know why some people are saying it's only 10 hp from his runs, wouldn't it show more hp on the dyno if it was just the Stillen intake on a bone stock car?

very nice review stillen owes you one, because they might have just gained another cutomer
But I wanted to clear up, the before numbers on the dyno are when you only have HFC's exhaust and jwt? If so, then what is stock to the wheel? Also, what kind of dyno is it? DYNO DYNAMICS, or DYNO JET, etc.
Thanks in advance...

I posted the top gains for both intakes since this is what most people and most companies do. All my previous review threads I posted the consistent numbers and not the max. I believe I stated that the sheets I posted were the max numbers. I actually had the wrong dyno at first when I was posting the review so that is why it is stated that way. Here is a dyno of the average or consistent numbers for both or close to it:
There is little to no loss between 5600 and 6300RPMs. Before that there is a big increase in TQ though. The increase is between 5 to 8 lbs of TQ across most of the band up to 5600RPMs. After 6500RPMs there is an increase of about 10 to maybe 12TQ. To me this is big. The increase of HP on the lower end is not as great as you point out but there is an increase no the less and the increase up top is great. I would recommend you stop looking just at just HP. There is a definite increase in power when I drive my car. I did not say it was "throw you back in your seat power" but you definitely feel it. If others say this then that is them. I don't know if you have any mods but if you installed some HFC or test pipes then you have a good idea of how these intakes feel over driving with stock except you don't have that loss of power in the low end that you get when you first mod the car. A ECU tune is definitely going to help. Now as far as our car not responding well to bolt-ons, I don't see that. I posted my best stock dyno and my Stillen dyno in the dyno sticky in the Engine section. 35HP and 17TQ from three bolt ons seem very good to me without an ECU tune. BTW my stock dyno run was done on the same dyno. Hopefully this answers your questions.
These are SAE corrected values. This was also displayed in the dyno sheet. The dyno shop is in Denver so the altitude is a mile high.

It was to make it easier to install the Stillen intake. The installs were done while the car was on the dyno so the front bumper was taken off before the car was put on the dyno.

I thought you can't add up all the hp of each individual mod and say that is what you gained? (e.g. say 10hp(intake)+8hp(HFC)+10hp(exhaust) wont' equal to 28hp on the dyno.) I don't know why some people are saying it's only 10 hp from his runs, wouldn't it show more hp on the dyno if it was just the Stillen intake on a bone stock car?
If you take a bone stock LS1 motor making 300rwhp and put some long tube headers on it, you may get 15 to 20 rwhp. If you take that same stock LS1 but with a supercharger on it making, let's say 450rwhp, then add headers your gains will be significantly more than 15 to 20 rwhp.
Rather than adding up all the gains on a stock motor together, I think it is safer to think of mods as adding a percentage gain to your current setup, i.e. if the headers in the above example made 15 rwhp on a 300 rwhp motor, that is a 5% gain. The same headers on the boosted engine making 450 rwhp would likely add 5% or 22.5 rwhp to the boosted setup. Likewise, if the Stillen intake made a 15rwhp gain on a stock VQ37 motor making 280 rwhp, that represents slightly more than a 5% gain. This same intake on a moddified motor should be able to generate a 5% gain over the moddified setup.
Then again... I could be wrong.
