Intake + Exhaust = what hp gains overall?
 

Hi all... after I got my CBE installed this past weekend, I am getting smitten by the "light" mod bug. I was debating between K&N drop-ins or just WIX filters for now, then maybe doing a G3 intake next time, when funds become available.

My question is this... I KNOW I have read all over here before of folks that have dyno'd their G3's and their CBE's either alone or together, but I can't seem to find the actual graphs of both of them together.

Can someone please either link me or point me or tell me what WHP gains I can see from just doing a G3 intake paired with a good quality CBE? I know I have seen folks get up to the 300whp range with just those 2 mods? I plan on keeping the stock cats and headers... just those 2 mods mentioned is all I plan to do. What do you think I will be laying down? anyone have graphs?

thanks!

p.s. Anyone's thoughts on WIX filters that run them in the stock intakes??? I'm worried about the K&N oil/MAF issue and also costs a lot more :ugh2:

Intake and cat-back together will yield between 15-20 increase in HP if you keep your stock cats, sorry no graph though. This thread should be in the intake/exhaust section.

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.

The Drop-in's add about 5-8 hp (see thread below) with a little more if you decide to add HPS Tubes.

Over-oiling with the K&N's is a non-issue as long as you follow the re-oiling instructions.

You can reach the over the 300 rwhp mark with a CBE and CAI, maybe a little more with an Uprev Tune. Every car is different and every dyno is different, so your gains should be based on baseline readings anyways.

Thanks for the feedback guys... yeah so for now, will be sticking with drop in panel filters, but am debating between going K&N or just using high quality paper filters like Wix or the like.

Anybody here use Wix filters??? If so, your thoughts? I tried searching for Wix, but I don't know how to make it search for only 3 letters :(

You can go AFE Dry filters if your afraid of the "oiling issue."

HKS is also worth a try, they cost a little less than the K & N's. Paper filters likes WIX are pretty much the same as OEM. I would just stick with the OEM Nissan filters if you want to go that route.

Like I said, nothing wrong with going with the K&N's. The Stillen Gen 3's use cone type K&N's.

Should be able to to see 15-20. You might see more off HFC's than intakes though.

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.

i made 300whp with k&n intakes and borla catback

i would say like 50HP, with a exhaust with a filter, to help with the Ox2 sensor to help with back fire and help with LOW/ HIgh end power. but then it might be a trans to help with a good custom tune. so the O2 air flow can cesspool, the reactor in time

You should also get a high flow cat or test pipe!
