What did you tell me in your post that I didn't already know?

I think you're misinterpreting my original statement, but I also disagree with your statement about intake gains after a tune. If I understand your logic correctly, you are saying that stock for stock an intake won't add power, and I agree, but I also think you're saying that an intake WILL yield power when coupled with other mods and a tune. I'm not sure I agree with that. I think a **** intake is always a **** intake. Also, I understand that Rob simply dyno tested the intakes, and he didn't get a tune for each application

IMO: Intakes don't add power (there is no intake that adequately insulates the filter element from engine heat), and any gains seen after a tune are solely because of the tune and not the "increased flow" from the intake.

 

Robs test were just solely for his car only. Any gains that were made will not result the same gain on another G. There are just to many factors for his testing.

As for my take on intakes. Yes the tune itself is the major role in hp. A tuned intake along with matching mods can produce better than oem intake. Even if it a 1hp gain with a tuned intake, it still proves better than oem. And its just not about HP numbers, the curve line is what matters most.

 

I would trade that 1hp gain at peak, or even over the curve for the protection the stock intake provides against heat soak, a real problem for the VQs in the G35. It's one thing to gain 1hp in cold weather, but lose 5 or 10 in warm weather.

As for Rob gains, we'll see. I want to actually see the test.

 

heat soak plays no roll while driving. Once the vehicle begins to drive away intake temps drop dramatically. Heat soak is overrated.


I have no heat shields on my intake and dont feel one bit of heat soak.


Remember Robs car (from reading the thread) has port work done. So how does that compare to a G without? his test is really meant for "which intake works best on my car" not others car.

 

Heat soak is a reality. I can tell you that from track experience. It's even a reality on the stock intake.

An SRI is compete garbage. Just because you cannot feel it doesn't mean the power loss isn't there. The loss is most noticeable from a dig, esp. at the strip. An open filter element right next to a hot engine and header is a terrible approach.

Heat soak plays a bigger role than you can imagine. That's not even touching the deposits most intake filter elements leave on the MAF.

 

Okay so my question now is... If you got a tune with a stock intake... vs an aftermarket say... INJEN with a tune as well. Which one would yall say would yield out better results? Also taking into account hot weather conditions on regular daily driving..

Where exactly does the INJEN place their filter? I have seen pictures of the engine bay with the INJEN but yet to see exactly where its placed. I know the NISMO CAI is placed in front of the driver side wheel, and I dont exactly see how that can get air flow being pushed in from that location? Unlike the Ztube and stock air box, air is constantly being rammed in from driving.

 

daily driving heat soak is overrated. Now in your case you track then yes, you'll most likely want a insulated intake. But also take in variables of oil temps, not just intake temps.


Now for daily driving, it doesnt matter. I disagree with a 1/4 mile track. Heat soak will kick it from idling, not driving.

Deposits is another topic. I wont discuss that since filters come into play.

 

I dont see how a stillen air box wouldnt make power, its 90% idential to stock air box but has a cone filter on it, con filters flow so much more than a panel

 

Then test it! With a dyno. It's still exposed.

 

Stop and go traffic is the same as sitting in the staging lanes. Any filter that's been eating up hot air right before take-off is going to dial back performance. I remember my CAI was made of metal and the tube was hot even right after pulling over from why driving. My plastic Z-tube STILL feels hot on warm days.

 

How do you plan on driving it? That is how you should tune it.

 

once the vehicle is moving; cooler air is rushing through the tube at much lower temps, than it was at staging.


just cause plastic cooled quicker than metal, doesn't mean the intake temps weren't about the same while vehicle was moving.

 

IMHO, there's a greater chance at HURTING performance (vs OEM) with aftermarket intakes than increasing it.

Not really worth the rehash x 100th time to argue about it.

 

^^^
I agree.

but the same can be had for possible gain and no measurable of gain.

 

There's only one aftermarket intake I'd use over the revup oem box. Stillen CAI. Which I have. But I'm currently using the rev up oem box.
