Fujita Air Intake on G37 Coupe
Exactly..I was talking about its weight in relation to its quarter mile times...not that dyno...
Its only running high 13's and even very low 14's at trap speeds less then the 07 Z...Now it makes sense..

Weight is the only thing that seperates the 07 G Sedan with the 07 350Z in terms of acceleration (Z with the upper hand obviously).

plus wheels on G37 is almost 15lbs heavier then the Rays on New Z33, I dyno my S14 with SR20DET and with same size wheels but with TE37 vs GTC the hp was 4lbs difference and 5lbs of tq diff..

Plus, once you start going down that road, the G falls further and further behind the 335i IMHO.
Heck, by those #'s the sedan is only 14hp and 2tq shy of the coupe.

So... confused a bit by the dyno #s I searched around, and it looks like those are quite low to some other dyno sheets.
http://www.automobilemag.com/reviews...7_dyno_charts/
(287 hp / 236 lb-ft)
http://www.edmunds.com/insideline/do...ticleId=121462
(281 hp / 229tq)
That is more what I expected.
Any thoughts as to why these are so low? Different type of dyno?

With all due respect, im not so sure if you understand the variables that goes into every dyno. Sorry but there is no way that same engine on the 07 Z & 07 G Sedan have a 10 whp & 13 whp. I've dyno'd my car several times and I understand how they work. I have had readings range from as much as +-10 whp on the same dyno with the same car all pulls within 5 minutes. Just shows how inconsistent and easy manipulated a dyno reading can occur.
Also, I won't believe that these intakes produce that much power unless its track proven. If it really did increase that much in power and torque all around the powerband, its definately going to yield better results at the track...if it indeed produces that claim in power.
Like I said, the only difference in regards to acceleration is the G35/G37's heavier weight figures. There's a difference in unsprung & sprung weight in regards to dyno numbers.
Also, how did you get those wheel weight figures? The 05-06 G35 Coupe Forged OEM 19's were one of the lightest 19's around; they ranges from 19-21 lbs each rim. I have a hard time believing that those G37 OEM 19's weigh that much more than the current OEM G35 19's and new Z33 wheels. Can you please share with us the info you have with proof?
PS. Please don't take this the wrong way. Just having a civil discussion

Track Proven? with My Z all my lap was never 100% the same, due to temp on tires, wear on tires, etc..
Also on dyno with unsprung weight, on my S14 I will be getting a lighter flywheel, driveshaft and changing the wheels to CE28N (same size) with R888 tires over all I know the HP will be higher then right now.

The G37 rims aren't forged to last I heard.
