jnjdragracing Posted October 4, 2008 Share Posted October 4, 2008 Well we went to the drag strip tonight and tried to make 4 passes. Did not tear up anything which is a good thing and nobody got hurt which means a good trip. We tried to make some complete passes but we had just too much power. I have posted the video footage of our passes at www.jnjdragracing.com please go to Zcar, then movies, then to the bottom ( Testing our new project ). You can read what we tried to do to cut back on the awsome power. but it did not help. Also here is a direct link. Please be sure to right click and save as, it is a 51meg video file. http://www.jnjdragracing.com/videos/New%20project%201-4%20test%20runs.mpg Until next time.....

Guest Zrocket Posted October 4, 2008 Share Posted October 4, 2008 Nice. Do you have a stock rear end. I have a 74 240z, with a 406 sbc, 144 mini blower, on alchol. We brake rear ujoints off the line. Quote Link to comment Share on other sites More sharing options...

Warren Posted October 4, 2008 Share Posted October 4, 2008 Time for wheelie bars!!! Quote Link to comment Share on other sites More sharing options...
deja Posted October 4, 2008 Share Posted October 4, 2008 Well you got the burnout part down!!!! Nice wheelies too, that's got to get Jerry's heart racing! Like Warren said do you think wheelie bars would help? Then again it got way loose on the first run without pulling air. We are all going to miss you if you decide DNI is pointless.

JustinOlson Posted October 4, 2008 Share Posted October 4, 2008 I'd say its time to tie down the front end to limit travel, along with some sort of timing retard box to help you get moving. Please guys make it work!!!!!!!!!! Quote Link to comment Share on other sites More sharing options...

jnjdragracing Posted October 4, 2008 Author Share Posted October 4, 2008 Now I never said DNI was pointless, if we can not get the Z to run down the track then there is no need in going. I will be hounding Jerry about it and at least we can attend to root everybody else on. Who knows I might be able to down size some power. I need to talk to enderle Monday and see how far I can retard the timing before it wants to sneeze, and also maybe under drive the pulleys. We will have to see......

G-rib-73-240z Posted October 8, 2008 Share Posted October 8, 2008 micky thompson 28x9x15 ET slicks. how wides the biggest you can run w.o widening the wheel well and flareing out the sides... i was wondering because i wanted to run some 10 inch mickey tompsons in the back on some 16inch rims... but now im thinking bout clearance.... not that my car will need them or anything but would be sweet to have lol or that my car has a motor or transmission lol Quote Link to comment Share on other sites More sharing options...
jnjdragracing Posted October 8, 2008 Author Share Posted October 8, 2008 We had to notch the fenders right behind the door and turn up the fender lips and clearencethe rear strut tower perches in order to run the 28x9x15. So if you plan on running 10 inch then be prepared to do some clearencing. John how wides the biggest you can run w.o widening the wheel well and flareing out the sides... i was wondering because i wanted to run some 10 inch mickey tompsons in the back on some 16inch rims... but now im thinking bout clearance.... not that my car will need them or anything but would be sweet to have lol or that my car has a motor or transmission lol Quote Link to comment Share on other sites More sharing options...
