HKS has made a intake for the 370 and I own one.

Great comments happening here and on the Project:Mothra facebook page -- Project Mothra | Facebook
One person reminded us that opinions are like buttholes -- for the record, we've already replaced the butthole on Mothra with a JDM fog light.:rofl2: Quick question for you guys -- there have been a couple of references to "F.I." made here and on the FB page. Are you referencing "Fast Intentions" or "forced induction"? It's not always clear and we'd like to answer everyone as completely as possible. By the way -- I mentioned last Thursday that we were having a little fun with a GT-R for Smoky to tune as well. We did a couple of pulls -- both with the Cobb on and with it off to see where we stand on that car. Here's a little teaser photo set, with more in-depth description coming... |
It can be tough when people just say FI, it all depends on the context of the post.
With you guys though, they might be referring to forced induction since you already mention you are going with another exhaust setup. |

ya, performance-wise: FI headers and cbe FTW!

Monitoring oil temps
The chief technician in charge of Project Mothra took some baseline numbers on the oil temperature before we put the NISMO oil cooler on. Using a CONSULT ECU diagnostic interface, he measured the following:
Under moderate throttle application: Oil temp= 224 degrees Under heavy throttle application: Oil temp= 238 degrees Air temperature outside was low 70s. The NISMO oil cooler goes on today or tomorrow and we will post temp readings after a test run. Thanks to all the forum members who've contributed here and on facebook: Project Mothra | Facebook The Amuse body kit goes on soon. Stay tuned! |
There's a rumor floating around that the Mothra car may be out at Planet Zero tonight, incognito, of course. The body kit is not on yet, but I hear Jason has made some real progress on the engine mods.

For all you oil temperature guys, this just appeared on the Project Mothra blog:
Warm reception, despite cold weather. On Saturday night Mothra was at Planet Zero's monthly lot meet for a sneak preview. Although the weather (38 degrees) kept the lot fairly empty there were a lot of questions asked about the Z. Hopefully, as the weather starts to warm up, there will be a bigger audience at these shows. People seemed to be impressed with the direction that we are taking and are looking forward to seeing what's in store over the next few weeks. On Saturday morning the oil cooler and a Stillen intake were installed, while we wait for the Top Secret Cold air intake. This "double-take" on the intake is a little labor intensive, but we wanted to get some numbers with the benchmark Stillen setup for comparison with the Top Secret one. Again, the guys over at www.the370z.com have engaged in quite a debate about oil coolers and track-bound cars, as well as healthy discussions about intake designs. This should answer a lot of questions in one or two fell swoops. We have noticed a drastic change in oil temperature since the install. Before, the oil temp under moderate throttle and acceleration would climb to 224 degrees. Now, with moderate driving, the temp will not rise above 167 degrees. Under hard acceleration and throttle conditions, before, the engine temp would rise to 238 degrees. Now, under those same driving conditions, the temp will not rise above 187 degrees. With normal driving the oil temp will barely register over 140 degrees. Keep in mind that these number were taken in 40-45 degree weather -- noticeably cooler than in days past. But regardless, there is a drastic improvement. Smoky should have one fine platform to work his magic. Now, if we could just get the Amuse body kit here before he lands...Stay tuned. We hear the AMUSE body kit is in-flight right now from Japan. Pics will go up when available. |
This build is looking pretty exciting. Let's see some pictures!

Dyno Today
Hello All,
Just a heads up, as promised we are going to the Dyno today, sorry for the delay, our parts were held up but have arrived. We will be dynoing the car today with the Stillen Intake as requested, as well as the Top Secret Intake, same dyno, same day, same car. As soon as we get back and get all the media together, we will make sure its posted!!! |

So, we're pretty satisfied with the validity of our experiment and hope all on the forum enjoyed this debate and findings as much as we did. Here are a few more pics. The first is one final look at the car before the Amuse kit goes on. The full set from yesterday are at: Project Mothra | Facebook We invite everyone to become a fan on facebook and to participate in this build through the discussions and debates. We really do value all the insights we get from this great Z community. Keep 'em coming! |

Looks like they finally got those Amuse boxes open over at Baker-Jackson Nissan. :tup:
They have a couple more on the facebook page. No shots of the back yet, though! |

I'm curious to ask. Isn't 140-167 alittle cool to be running the oil all the time? I do not currently have an oil cooler on my car but temperatures that cool seem to alarm me with condensation in the oil? |
Found this video the other day...
|
Now that is one bad Z. Love the side bottom stripes. Can't wait to see more of this car.

hot differential: No extra front ventilation cold differential: ventilation similar to my Fang Vents run to the CAI inlet Trim: Removing the rear gasket between the hood and firewall to promote airflow through there.. 35 minute Test run from start, through a little traffic, some country roads, then traffic and 5 minutes idle in the driveway. These are the temperature differentials from Ambient (70 degrees on the day of the tests). Temperature dattalogger sampling once per minute. The fact that we can only get IAT's down to within 7-10 degrees of ambient on the 370, no matter what the intake or feed system, would indicate that heat in the engine bay is a factor, even underway...You just have to deal with it as the IAT sensor does..Remember, the engine is running ap 180-190 degrees (Coolant system regulated) Not all that heat is expelled at speed.. Pull that rubber trim off to promote ventilation through the rear of the engine bay results in some nice temp improvements as you can see! http://images115.fotki.com/v672/phot...erences-vi.jpg |
I knew you would come through on this one modshack, nice analysis :tup:
|
the amuse kit looks so sweet...the rear side looks like a porsche 911

Pic below... The base of the windshield is a high pressure area...removing the gasket allows air to be drawn into the engine bay. You won't see a decrease in actual engine temps, but you will in engine BAY temps, which is good. I've measured this on several cars (Audi TT and Corvette)and found about 18 degrees to be the difference. I need to do it on the Z. here's the Audi chart: http://images46.fotki.com/v1483/phot...comparo-vi.jpg Remove these to let some air in! If you really want to ventilate, pull the plastic cover over the strut bar bolts at the firewall http://images56.fotki.com/v1598/phot...MG_2498-vi.jpg |
Thanks, Mod!
