You will see definite improvement of whp gains after the HFCs.

Because of 370Zs dual intake system, compare to single on 350Zs, the intake kits are now about par with HFC, sometimes even cheaper.

It's your call, if you buy HFC, you'll eventually mod your intake system anyways.

Either way, gaining HP is better than not gaining any.
Catch 22, in a good way...

Very well said

HFCs by a good margin.

semtex · 09-01-2009, 10:55 AM

Before: Max = 291.7whp. My only mods at the time were the Stillen cat-back exhaust and the Berk HFCs.

After: Max = 306.4whp. (Added the G3 intakes and re-dyno'd 10 days later.)

Net gain = 14.7whp.

and dyno dynamics read low too

Agreed. And that's why on that very same day, I went and did a dyno on a DynoJet, just to get an idea of the difference in readings between DD and DJ.

DynoJet results, for comparison: Max = 321.3whp

You have asked and you shall recieve. Pretty much bang on with semtex with a net gain of 15.3hpatw. Also done on a Dyno Dynamics, I'm not sure about getting another 30hp with the exhaust though. Semtex did you get a baseline run done at all?

RCZ · 09-01-2009, 05:32 PM

You got the same response here as in my pm. I got gains everywhere honestly the car felt better overall. Like someone said, it works better when you free up the exhaust too as the freer flow from the intakes has to go somewhere.

I just bought and installed G3 intakes today. I do feel quite abit of a increase in power...especially as the rpms get higher.

3SeventyZ · 09-02-2009, 06:31 AM

cant wait to get mine put on

NewYorkJon34 · 09-02-2009, 10:58 PM

Im ordering the G3 intakes this week, what should I look foward to in terms of differences from stock?

Snakes709 · 09-02-2009, 11:00 PM

like stated above...between 10-15hp...i felt a nice increase from stock. You can hear a difference also, i didnt at first but now as i listen i can hear the air being sucked in.

NewYorkJon34 · 09-02-2009, 11:18 PM

^ Is is alot louder from stock?, I am excited to install them when they come, I really wanna feel the difference that everybody is talking about

Snakes709 · 09-02-2009, 11:26 PM

its not crazy loud. Might be different to other people but to me no, im not used to having a N/A car...once i installed my intake on my Cobalt SS Supercharged, all u hear is the supercharger whine. Now that i have a N/A 370z...different feel, different sound...sound increases but not alot, u will hear a whirling sound i guess u can say.
