Cold Air Intake HP Debate - Is it worth it ?

GZ3

wow all that thread proved was that r2c has better more useable power and g3 has higher peak numbers

under the curve > peak

The VQ37HR is not some magical engine. It has always been a small difference between a short ram vs a cold air anyway. In the end, forced induction is the key. (All motor setups are usually dominated by American cars, Hondas, and rotary engines)

TBOX

I'm sorry but this makes no sense to me. Are you trying to say a Honda, an American motor or a rotary are superior NA builds?

A: name a Honda motor that is superior to any other motor for making power, hondas rely on weight and high revving motors but in reality compared to any other choice are a horrible option for power.
B: point me at a rotary NA build that makes power... The wankel was and is a failure. Don't mistake the brilliance of the handling of rx7s and rx8s and their power potential.
C: you don't mean American, you mean displacement (which is the typical route for American muscle cars) which will always make more power on an NA build

Nikkolai

My statements are all based on after market parts and builds that have been done over the years. I am not sure about the rotary though, since all I have seen are 4 rotor builds and a naturally aspirated build done by RE Amemiya that output 400whp. I know that the Nismo 380RS is rated at 380hp naturally aspirated but I am not sure if many people go with the n/a route.

honda s2000k over 100hp per liter n/a . nissan cant touch this. period

Yes hp/liter s2000 and even them rotary potaoes are some of the top contenders, but I wouldnt consider them the top NA cars. No matter, we're derailing.

BLM

Actually, with an exhaust swap and a tune you'd be pretty close to 370 bhp and though the 120 HP/liter is impressive on the s2k you sacrifice a lot in terms of low-mid range power with a high revving motor like that.

Yep. A fully bolted on tuned Z will definitely be there at the crank, espcially if we use ps units, which are a few % higher than hp units.

VVEL tuning, I predict, will be the key to really getting a NA motor to wake up tho'.

Actually that 2.0 sr20ve is a good motor, I just did a swap at my sbhop into a 99 sentre se.

Did Nissan buy the rights for the variable lift from Honda? I was studying these motors a few years back, and it was a blatant copy of VTEC.

With a decent driver, they will leave a Z around most tight road courses.

Me old 1997 BMW M3 with the euro S50B32 engine delivered over 100hp per litre also. It was a 3.2 litre unit.

I've heard the F20 and F22C are pretty solid at making power (only through rumors of course) and the K series is also pretty beastly as well. I've seen plenty of guys laying 250whp+ out of a 2.0 with just bolt-ons.
