Only one: HFC, Gen3 Intake, or CBE?

semtex · 06-17-2009, 02:14 PM

Do the HFCs. There are some new CBEs about to come to market. Doing the HFCs first will give time for these other players to get their CBEs finished, which means you'll have more choices. Berk, for instance, is preparing to release their own CBE for the 370Z.

Where's the option for the ECU flash? If you are serious about performance, that is your best bet. My first call will likely be to Technosquare for a 93 octane specific performance map.

If you don't care as much, anything you have is fine because the change in sound/performance will likely satisfy your i-modified-my-car jones.

If you're going somewhere like technosquare, it will be more cost-effective to get all bolt-ons done prior to doing a reflash.

I was about to say the same thing. Getting a reflash prior to completing all your bolt-ons is a complete waste of money.

Thanks guys, definitely appreciating the advice and look forward to anyone elses opinions.

I haven't found any clips of Berk HFCs alone. At this point, I have no problem with having a louder exhaust as long as my car doesn't sound like a rice cooker. Do the HFCs alone have a nasty buzz or does the sound mature with some time to keep a good, sporty note?

As you noted, the HFCs are cost effective and none of these bolt-ons sound like a challenging install.

Semtex, you can disagree all you want, but the fact of the matter is that changing the tune first will yield good gains. In addition, much of the gains in power from the aftermarket intakes isn't from additional airflow, the stockers flow just fine, it is actually from changing the MAF signal to read less air is flowing and thus leans out the charge to a more ideal ratio. Those disputed tests where the guys at 370z.com held the air-fuel ratio at stock levels proved that the power gained from additional flow was minimal. This points to where the intakes make most of their real power, which is changing the reading and thus the combustion mixture, not from additional airflow. If you were to take a stock 370z and flash it, you will see good gains.

And as further proof, this has been done and tested at 370zdotcom.

Had they gone with a better map, their gains would have been greater.
