Stock vs. ERZ.....and a cantaloupe:

Thats a big difference and the new ones look better than before. +1 rep

Are the o2 sensors open? If so will that affect anything?

Not sure what you mean about the O2 sensors exactly. They aren't hooked up in these pics but they plug in just like stock except the bungs are extended on the ERZ cats

I guess I meant the other plugs in the pic. The short ones. I think they are used for dyno tuning. Are they open and will that affect anything.

Sounds great. And not too loud just cruising either.

puckshaw · 03-07-2010, 08:41 PM

Thanks guys

You can't even really tell they're installed when just cruising but as soon as you give it some throttle it comes alive. Still not extremely loud but it changes the tone completely. I'm finding there is a bit of rasp ~3800-4500 RPM. It's not a big deal to me though. I'm very happy overall and the power gains are definitely noticeable

@puckshaw

awesome vid! just to confirm your only engine mod you have is the ERZ HFC? Do you or anyone here know what's the dyno gains if this is the only engine mod to the Z?

Don't think anyone has dyno'd the ERZs yet. However, they should be on par with the other HFCs and good for about 15-18 rwhp.

Spearfish beat me to it. I was going to say the same thing

true that any 200 cell HFC is gonna get you in that range, one companies product might look better and even be built better but as long as the cell counts are the same they will be fairly equal in gains. Same with the CAIs and CBEs.

Oh and yes my only engine mod is the ERZ HFC.

So you should have some good gains. I think, and FIs thread shows i too, that even though the HFCs should get you 15 and the CBE should get you 15 and the G3 should get you 15, that the first mod wether its the CAI, HFC, or CBE will get you that gain, but I think all the mods after that only net a few each. Fi showed that when they dynod their HFC with a CBE on already and only got about 3 hp. So I think the first mod opens things up good and the following mods only net a few. Id love to see a dyno of all three without any other mods to see what they do and then add a mod, dyno again until you have all three on and see what the final results would be.

This. I'm wondering if putting HFC's on my Nismo will even be worth it. It is a lot less expensive and intrusive than intakes or replacing the full exhaust though.
