    Hey all, Wondering how fast (ET) any of you have gone in the quarter with stock 280 stub axles and flanges? I am not pushing mine very hard with an auto, and a tight converter, and running 12.05 to 12.08. I am putting it up on the converter to stage, so everything is preloaded and there is minimal shock.(235/60 mickey dr's)

     

    I would like to upgrade the heads, cam, ect, Should I upgrade the stubs before I go any harder? Thanks.

    Yesterday I went a 8.43 @ 166 mph.

    R200 is a BEAST!!! ( Personal Best )

    This past weekend I took the Z to the track after doing some updates. The last time I had it at the track was April 2018. I went to Thunder Valley Dragstip in Red Springs, NC. First pass I snapped the 4 bolts that bolt the driveshaft to the pinion flange. I can’t complain because they have been in the car for 12 years. I got them replaced. Went to the starting line and went a 5.23 in the 1/8 th did not have the mph. Now guys this is a stock R200 with 300ZXT CV axles and stock stub axles. First off all the glory to God!!! I have a Great friends and family. Thanks

    We are running the original stubs and rearend  that came in my Z. It is a 1976 280Z we have had a 412 sbc with NOS, 355sbc with 671 blower on C16 racing gas , same motor and blower but with Alky and a Birdcather mech fuel injection, and now a 355sbc with twin 65mm turbos with E85 EFI. we went 9.21@153 on the stock haftshafts with the blower on racing gas, we then went to the 300ZXT CV axles, and the car went a 5.61@129mph and a 8.67@158mph in 2012 with the turbo setup. The car now runs 5.40@135, we have not run it in the quarter since 2012 but it should go a 8.40 @165+ in the quarter.The last time we dynoed the car it made 945hp at the rear tires.I hopes this sheds some light on your questions.We have been running this car for 12 years now. Jerry

    That 8.67 @ 158 mph was with a 5.61 @ 129 mph in the 1/8th, the car now runs 5.43 @135mph, and should go in the low 30's ,that should be a 8.38 to 8.40 in the 1/4. I will be talking it to a quarter mile track when it starts cooling off. Jon Phillips 1QuickZ does run the corvette center section with custom 4x4 axles with u joints. Thanks for the shout out RebekahsZ!

    Thanks, Hans (Turbo Meister). Well now that you mentioned it I have had a nine inch and ladder bar set up for 5 years and this might be the year, I want to hang it out in the 1/4 one more time. In 2012 it went a 8.67@158 with a 5.61@ 130 in the 1/8th. And now it has been a 5.43@135 it should go a 8.38 @160+ according to my calculations. I believe the car can go a 5.30 now or high 20's, I hope to find out in a few weeks we will be doing some more testing. The LS motor will be in the future.

    Well I have been running sbc (Gen 1) for a long time, but purchased a 2001 5.3 today. So I will be trying to find the best direction to go with the build. It will have twin turbos and EFI. I hope this is a okay platform to start with. The motor was running but had cold start up lifter noise, only $250.00 complete so I think it was a good deal. I will continue to run the 355sbc for now, but will be working on the 5.3.
