Sweet, some nice rides.

Unique_Z · 06-01-2013, 02:32 PM

woah 382whp?? cool!

datykoo · 06-01-2013, 02:43 PM

I am very curious on how they achieved this much on the VQ37. Did they stroke up the engine? if not, did they increase the rpm redline to maybe 8500+?
making 380 WHP on a 3.7 litre engine NA with just a 7500 redline seems a bit impossible to me. Not trying to say they are lying, just curious.

correct me if im wrong but isnt that a veilside? and the fenders maybe custom? that hood is hella... aggressive....

Gaston370Z · 06-01-2013, 04:02 PM

Interesting that the 370 still has the stock intake air boxes and tubes.... 382rwhp! Did you get the magic formula for that kinda power?

Also probably on 100 octane so that helps a little but still really impressive numbers!

Chuck33079 · 06-01-2013, 05:20 PM

Isn't that the car that has different pistons in addition to the cams?

Gaston370Z · 06-01-2013, 05:37 PM

Id be willing to set it up for E85 and build the engine like this.... Na power is so sexy.

Thanks guys for the response to the pics and videos. I tried to make sure I got enough for you guys. Yes the pistons are high compression and the bore and stroke are stock. The fenders are something that Circuit Concept out of Japan is working on. Most of this car was created through Circuit Concept. I am sorry i didn't get a pic of the engine strut bar but its Titanium wrapped in dry carbon Fiber. You can go to there website and check it out. The hood is dry carbon as well. I felt the weight of it and omg it was finger operable. The fenders is something they are working on right now and they used that car to do a fit test and it was sweet. The fuel here goes up to 100 octane at the pump so yes he always uses 100 octane. I asked the same question about the stock air boxes and he said the owner was really happy with them and HKS filter inside. Mind you he could get more power out of something else but that is his choice. Of course I am really only interested in power and staying NA so I asked alot about the VVEL and the programing. JUN is working directly with Nissan Japan to change the programing table for the Z34 so users and companies are able to adjust the intake side and VVEL on the car. JUN swapped the intake rods out and found no gain from that so the next step is to mess with the VVEL actuators which they are in the process of doing. I wasn't able to get pics from Top Secret or Zele cause they didn't have any performance cars there at the time I went and I didn't stay long. I will be back in my car in a week and when I get back I will take video and pics with my complete cylinder head build. Any more question let me know
