Cold Air Intake HP Debate - Is it worth it ?

Daishi · 04-03-2011, 06:24 PM

His argument was that Nissan can't come close to 100. So thats what I'm basing my argument on. But regardless the 2.2 at supposedly 238 HP dyno more to the wheels than the 2.0 at supposedly 240 HP. Either way I'm sure Nissan can improve HP per liter but at what cost? Lower rpm power and shifting the power band way up top like the s2k

Lol wow, sparked up some heat here. All I wanted to state was the aftermarket support. Lots of naturally aspirated built engines out there in the Honda world. I do not consider bolt ons (i.e. on a Nissan) as a naturally aspirated build (part of it, yes, but I am talking about internals).

I am not a honda or nissan fanboy, name 1 box stock nissan or and " normal" car that comes close to 120 hp/liter? So it not a false statment, it a fact. At 120 hp/ liter the z needs to make around 450 hp. Yes the s2k makes no tq and yes it is tiresome to have to rev it to go anywhere. I can't think of 1 nissan the hit 100 hp/ liter.

Mazda RX8=178HP per litre
LF-A= 115HP per litre
458 Italia=126HP per litre

Haven't heard many mention the Injens ( feel free to coment on these). Anyways, in the end we won't really know the answer to the op's question unless we put this to the test. I don't think anyone wants to take the time to do this. Our cars are already well designed in the intake dept but like someone else said here, it all comes down to personal preference. "I" believe that colder air going In has to have a slight advantage in the overall HP/tq gain dept but that's just me....

Rx8 has a rotary, not to mention it was grossly overrated.

I was unaware the LFA and the 458 were "normal" cars...

I'm aware the RX-8 has a rotary, I use to own one. HP ratio per liter still applies here since we're talking about the engine itself and not the car.

I thought he meant normally aspirated, as in no FI.

I'm just saying, this is a relatively moot argument. Power to weight ratio is a more accurate measurement for performance.

Normal ==not $300k.

Comparing HP/liter between the rotary is inevitably misleading as well.

Nobody said it is the best measure for performance, it's just a pretty impressive feat that we will likely never see again in a sub-$100k car.

Yes as "normal" I meant cars that are most of us price range. Now there is debate on hoow much displacement it has weather 1.3 or 2.6 liter...

I would go for the g3 forsure!! I have em on my car already

Forgot to mention, mine is not a daily driver. Will never see rain..Again, its all personal preference. For some, its also what better suits their daily needs...

sr16ve. a 1.6 liter motor with 200 hp. similar to a b16b japan only type r motor. oh and the sr20ve vvel motor. 197 hp from 2.0 liter. both had vvel heads. sr16ve i think redlined at 8500 and the sr20ve redlined at 8000. watch out for se-r sentras with these motors dropped in, they can b very quick.
