Racin_Jason Posted March 1, 2001 Share Posted March 1, 2001 Ive realized that LSD's arent common in 240's but Im sure some of you must be running the open rearend with a V8. I also know that TRACTION is a main topic among HybridZ owners. I'd like to hear your experiece with leaving the line in a non-LSD Zcar. I understand that you cant have 400hp and just drop the clutch/floor the auto..unless you want one VERY bald tire Im just curious how much you have to baby it out of the hole and also once your moving does it smoke the tire at the shift?

scarp Posted March 1, 2001 Share Posted March 1, 2001 I believe NOSZCAR runs an open diff. and it seems he runs just fine. check here. http://scarp.homepage.com/noszcar/noszcar.html I have run an open in the past as well as a Quafie (sp) and I liked the Quafie but lived with the open just fine.

Andrew Bayley Posted March 1, 2001 Share Posted March 1, 2001 There's actually quite a few of us here that successfully drag race with open differentials. The reason for such success, is because of it's independant design. In a solid axel car, the torque of the driveshaft will also create a torque load on the axel. This will cause one wheel to tuck up into the wheel well and become more unloaded than the other. This is what cause the natural phenomenom known as "one wheel wonder". In an independant rear suspension design (like the Z's) there is no solid axel. All the torque loading is kept in the differential. This is the primary reason that an open diff in an IRS setup will work so much better than an open solid axel. Also, when the tires finally let go and start spinning, most often both wheels will equally spin. Again, this is because both of the wheels have a relatively equal load on each wheel. The big thing to remember, is to keep the rear wheels level with each other. The primary cause for one-wheel-burnouts is unequal wheel loading. With our Z's, we have all been blessed with an IRS leading to better holeshots with stock suspensions. If you want to see some performance times for various Hybrid's, go here:http://grannypotts.freeservers.com/Times.html I think everyone except Ron Jones and Mike Kz has an IRS setup. -Andy [This message has been edited by Andrew Bayley (edited March 01, 2001).] Quote Link to comment Share on other sites More sharing options...
Racin_Jason Posted March 1, 2001 Author Share Posted March 1, 2001 Wow, I guess the IRS isn't to bad then with an open diff. I know before I put the first locker in my Camaro (solid rear axle) it was most definately a "one wheel wonder"..lol. I'll have a look at those links. Thanks much for the quick response!

Racin_Jason Posted March 1, 2001 Author Share Posted March 1, 2001 OK OK...you have GOT to be kidding me that NOSZCAR is running an open diff and hookin like that! I found that video earlier this week and it had a shortcut on my desktop at work for 2 days If that car has an open IRS...i'd really like to know what his suspension consists of. NOSZCAR are you there? (BAD Z BTW!) Quote Link to comment Share on other sites More sharing options...
Guest Fast Frog Posted March 1, 2001 Share Posted March 1, 2001 Andy Bayley: I clicked on the website(grannypotts...etc) that you posted on this thread. It gave me your introduction page but that's all. How does one get further to see the performance times that you've posted on that site?

Racin_Jason Posted March 1, 2001 Author Share Posted March 1, 2001 Hey FF..FYI it worked for me. I just scrolled down and the times were listed . Quote Link to comment Share on other sites More sharing options...
Guest Fast Frog Posted March 1, 2001 Share Posted March 1, 2001 Too bad I'm not as handy with computers as I might be with other things. I get Andy's performance times for modified Datsuns home page but no scroll capability - it's like something is missing. it could be my machine-it's a 166 and a junk heap!! It might be the network-I'm using my computer at work. Any ideas????

DavyZ Posted March 1, 2001 Share Posted March 1, 2001 Keep trying it! At first it didn't work for me, then all of a sudden it did after trying it again. To recap the video: NOZCAR hooks well and spanks a very fast RX2 or RX3. If that was an 11 sec run, which I think it was, YIKES!!! That is one fast Z!!

blueovalz Posted March 1, 2001 Share Posted March 1, 2001 My suspension is set up for road racing, but all the same, I get two perfectly even marks on burn-outs. Not even 3" difference over several yards. Terry Quote Link to comment Share on other sites More sharing options...
Andrew Bayley Posted March 1, 2001 Share Posted March 1, 2001 Yeah, that's some serious traction in that NOS Z car video. I think he's is the quickest IRS Z car on this sight (I believe he runs low 10's or high 9's ) I really need to get a video of myself launching this year!!! Rick, if your going to blame something, blame my server. It its r... e... a... l... l... y... ... ... S... L... O... W... !... Keep trying and it should eventually load. -Andy Quote Link to comment Share on other sites More sharing options...
Mike kZ Posted March 1, 2001 Share Posted March 1, 2001 Rick, I've noticed that with Netscape I can't access the list either. But if I use Internet Explorer it comes right up. ------------------ http://members.tripod.com/~SnowSurfer/mikekz1.html Quote Link to comment Share on other sites More sharing options...
pparaska Posted March 1, 2001 Share Posted March 1, 2001 Just my unqualified opinion, but the Z is one of the easiest car's around to drive at the limit. I used to spin/slide around every corner in the rain, snow, etc. with the 6 in there. Granted the V8 will cause it to be even more spinny, but I can imagine how it will still be very controlable. That's exactly why watching Darius's spinning in all gears video didn't bother me too much. It seemed he was letting off and the car was back in control immediately. But this is also the reason I went to the LSD - to get better control leaving the turns under throttle. ------------------ Pete Paraska - 73 540Z - Marathon Z Project pparaska@home.com Pete's V8 Datsun 240Z Pages Quote Link to comment Share on other sites More sharing options...

Kevin Shasteen Posted March 2, 2001 Share Posted March 2, 2001 I too had the same problem; had to make the switch before it came up. I'm curious, Noszcar, what'd the Camaro driver think after being spanked by a Jap car? Pretty Sweet video.....now when is my Rich Uncle gonna die so I can get all his riches and begin my Alluminum V8 swap...oh yea, I dont have a rich uncle(?)!

Thanks for tolerating the newbie Jason im running the open diff r200 and i dont have that much trouble launching, if i want to burn rubber i drop the clutch and floor it at any rpm to achieve some nice two leggers, but to launch i usually feather the throttle at 2200, and i run 205-70-14's and get them to launch fairly well, anyone with a r230 lsd swap in the house???!!!!! my true disappointment, is dumping the clutch into a right turn and leaving a one legger though........im running a m20 four speed right now, i get some wheelspin, but control with throttle feather until i feel i can floor it without smoking up the block!!!!! i dont know i cant really explain it, but i can do it subconsciously.,....

MYRON Posted March 2, 2001 Share Posted March 2, 2001 Jasons car does, maybe did have, an open diff in that video. He did have to fix it once before and he told me how to fix mine(now belongs to ChrisT). The weak link is a small roll pin that needs to be replaced with a solid one. My previous car would hook like crazy in a straight line but if you had a greater load on one or the other tires it would light up just one tire...

Guest Anonymous Posted February 10, 2003 Share Posted February 10, 2003 I run a totally stock rearend behind a 355 dart heads, 420hp approx. on Futura 215-40-14. Yeah there is no 1st gear really but second hooks decently. I just love racing these LS1's and spinin right beside them then hookin up in 2nd and walkin em.
