I have searched these threads and cannot find the info. I just put the Nismo Exhaust and CAI on my Z and was wondering what type of HP gain people have documented. The dealer said around 10% which would be 28hp but would have to dyno to know for sure what actual would be. (sounds a little high to me)

Just wanted to know what I could expect in gains, I know every engine will have some variance.

I have a 05 Grand Touring Roadster. FYI

 

I would assume. The plenum spacer is looking awful good right now.

 

Thanks for the reply. What would the plenum add in HP gain.

 

AAM offers their angled plenum spacer (http://www.alteredatmosphere.com/mm5...de=350Z_INTAKE)
they advertise 10-15 HP increase .... I just got this is in the mail today and it looks great!

It would not add 28 hp. No. Maybe if you were turbocharged pushing a high amount of psi and you were on stock exhaust, and then changed to the nismo it would yield that much. And the Intake wont add that much either.

 

nismo exhaust n cai prolly give u 10whp the most if i'm not wrong

 

I am going a similar route. I got a nismo exhaust,and a pop charger. I have a 5/16 spacer on the way. The exhaust is supposed to get you 6HP, the pop charger 5HP and the spacer gains12HP. However, I don't think these are all linear gains you can simply add up.

 

Correct. With just the exhaust and a CAI, I'd be surprised if you made more than 8-10 HP. Guys on the board with ALL of the major bolt-ons are barely picking up 28HP, much less a cat-back and intake.

 

motordyne 5/16 spacer is THE BEST! i just installed mine a couple of days ago and i can tell a difference BIG TIME in torque and hp gains...butt dyno ftw
