Megatherion Posted June 20, 2010 Share Posted June 20, 2010 I really don't know what they're saying but the videos are pretty entertaining. part 1 http://www.youtube.com/watch?v=d0ooTo1H-hE part 2 http://www.youtube.com/watch?v=EYP59jUcV0k Quote Link to comment Share on other sites More sharing options...
Administrators BRAAP Posted June 20, 2010 Administrators Share Posted June 20, 2010 That was fun to watch. Thanks for sharing. Quote Link to comment Share on other sites More sharing options...
10cjennings Posted June 20, 2010 Share Posted June 20, 2010 Awesome video! In part 2 can anyone provide some insight on what the green S30 (they talk to the owner almost the whole video) had under the hood? I didn't see anything that looked like a No2 set-up so he put out a 10 second run out of an N/A straight 6...That's impressive. Quote Link to comment Share on other sites More sharing options...
T-Bone028 Posted June 22, 2010 Share Posted June 22, 2010 The header on that Z in the part 2 video was a piece of art...even with all the header wrapping! Thanks for sharing! Quote Link to comment Share on other sites More sharing options...
jgkurz Posted June 22, 2010 Share Posted June 22, 2010 The green Z ran 10.92 @ 198KPH/123MPH. That's amazing with an NA motor and no nitrous. He's got to be making close to 400HP. Quote Link to comment Share on other sites More sharing options...

Read this? http://forums.hybridz.org/index.php?/topic/90037-japanese-na-l6-400hp-how-they-do-it-pictures-ive-found-etc-not-56k-safe/page__p__854228__fromsearch__1&do=findComment&comment=854228 Its just about like... general stuff, but I think some of the green Z is in there. When you get that under the hood view in the video, what do you see? 50-55mm carbies, not too sure which. 50's are used a lot for those guys but 55's are also used sometimes from what I've seen. Big carbs don't flow well at low RPM. TonyD gives a good explanation, which you can piece together with the other information such as the horsepower formula which basically widdles down to having a good amount of torque at higher RPM, where most of us have torque drop off into the gutter. If I remember correctly, torque was around 200-250 even at like 7000RPM (don't hold me to that though). TonyD also made the point of dyno calibration, which I suppose makes power figures close to moot, compared to 1/4 mile times. -Big ports -Big carbs -Header dimensions (length, diameter, collector) -Well balanced/engineered motor to perform high RPM's -Torque at higher RPM's = more horsepower -Preferred transmission/rear end ratios for drag racing Read over that thread if you're interested. I'd recommend going over it just for reading pleasure, aka toilet reading, because a lot of the stuff is jibber jabber I wrote up and I can point out a couple things in there now that I know are incorrect in some fashion. I'm not a professional. Edited June 27, 2010 by josh817 Quote Link to comment Share on other sites More sharing options...
josh817 Posted July 16, 2010 Share Posted July 16, 2010 (edited) Found a video you guys may like showing the throttle response I guess with the Wako 75S cam, sounds good and healthy!: Same guy blowing up his tranny: Edited July 16, 2010 by josh817 Quote Link to comment Share on other sites More sharing options...
lifegrddude Posted July 17, 2010 Share Posted July 17, 2010 Awesome video! In part 2 can anyone provide some insight on what the green S30 (they talk to the owner almost the whole video) had under the hood? I didn't see anything that looked like a No2 set-up so he put out a 10 second run out of an N/A straight 6...That's impressive. From what I can understand, it's a 3.2L "kit" which that garage offers. It consists of a custom made crankshaft, pistons, connecting rods, pulleys, and is running a 4.375 R200 rear end with a Trust 5 speed Nissan Silvia transmission. Engine power is 392ps, and best time was that day of the video at 10.91. Carbs are 50mm Solex units, with custom made exhaust manifold and exhaust system. Prefers to use Solex over Webers due to ease of tuning. Pillow upper mount suspension, spring rates are 4kg/mm up front and 5kg/mm in the rear. Some custom work underneath and he's searching to get at least another tenth faster in the 1/4 mile. Hope that helps you out, but my Japanese isn't fluent enough to catch everything.

josh817 Posted July 17, 2010 Share Posted July 17, 2010 I'm surprised it was a 4.375 rear end rather then a 4.8 or a 5.1 that a lot of them use. Interesting! Quote Link to comment Share on other sites More sharing options...
