Intake + Exhaust = what hp gains overall?

christian370z

I recommend not doing the panel filters and just wait until you are able to do it right and get the G3 intakes. Most people see a 15-20rwhp gain over stock with the G3/CBE combination, I personally dyno'd at 310rwhp with G3 intakes and Berk HFCs with the stock CBE which was on par if not higher than other 370zs with intakes and a cat back on the same dyno.

I never did a baseline however.

Thanks for the response. 15-20 whp right?

And yes, if this is in the wrong section, please move mods. I figured, it'd have more visibility here, and also since I'm talking about hp gains overall, maybe it'd be fine here???

holy moly... 310whp from just G3 and HFC, and using stock CBE?!?!?!?! wow.

Question then, since I have my CBE now, if I go with the G3 and also go with say, a Berk or FI HFC, would I need a tune to run all 3 mods?!?!? Or can the stock ECU run it safely?

I would highly recommend at least getting your A/F ratio checked if you install G3 intakes which would be done if you get it dyno'd. Intakes have a tendency to lean the A/F ratio out which in my case and many others, it too lean for comfort (I had some detonation) which a tune took care of for me.

Yep, 15-20 whp. Not to downplay Christians 310 whp, but what you are more interested in is the difference from your baseline. Every dyno provides different results, so the net gain is more important than the peak numbers. A tune after those mods is not required, but many (myself included) do it because it will help clean up the A/F ratio and you may be able to squeeze out a few more ponies.

I realize that, which is why I only compared my power output to other 370s on the same dyno. Almost all stock Zs will yield very similar results on the same dyno assuming they were properly broken in and have no outstanding issues.
