briann510 Posted May 29, 2005 Share Posted May 29, 2005 after 5 weeks of rain delays we finally got to the track last wednesday with a video camera. we had a few 12.80 runs a month or so ago but didnt have a camera with us to record them. pardon the low video quality as its only a hi 8 camera. on his winning run of 12.909 on a dial in of 12.90. the track screen time got missed at the last moment on camera when i got bumped by someone. the other run in the video was a 13.024 with a dial in of 12.90 and he let up on it in first when he was spinning badly or he probably would have nailed a 12.90 also on that run. he is still spinning in 1st (with a 2.0-2.1 0-60 foot times) and chirping 2nd and 3rd, even with drag radials. he doesnt do a pre-burnout which probably hurts, but we need a line loc to do some decent burnouts.

datsunlover Posted May 29, 2005 Share Posted May 29, 2005 Awesome! Seams like there's some more 'pull' to be had in first, but I guess if they're spining, they'll just spin more with more revs.. I'll bet if you can find more traction, you could get a better shift to 2nd too.. probly pull a reall low 12.. Actually, without fouled plugs/valve seal problems, it should go even better..maybe mid-high 11's?! Love the sound too.. what are you runing for an exhast?

Jsquared Posted May 31, 2005 Share Posted May 31, 2005 congrats on the times, can't see the video though since I'm on dialup (maybe I can watch it at the library, hehe). Pretty cool to see what kind of times an NA car can pull off... and it puts a decent perspective on the difference a lighter car makes (my perspective is 2600-2700-lb 240SXs...)

kj280z Posted June 1, 2005 Share Posted June 1, 2005 Brian, Did you happen to put your car on the scales that day and get a race weight (with you in it)?... Quote Link to comment Share on other sites More sharing options...
1 fast z Posted June 2, 2005 Share Posted June 2, 2005 You need to get rid of that wide ratio tranny. Here how much it bogs when you go from 2 to third? The ratios would work out MUCH better for you with the 81-83 NA, or out of a Maxima. Quote Link to comment Share on other sites More sharing options...
briann510 Posted June 5, 2005 Author Share Posted June 5, 2005 Ken, no we havnt got it on a scale yet. everytime we are at the track the scales are closed. my son weighs 300 lbs and is 6'4", so thats no helping much in the light weight department..LOL Bryan, that "bog" sound is from not running air cleaners on our triples. it is not from too much of a drop in rpms ratio wise between gears. you should hear another video someone shot of those runs from the end of the track as car was coming towards the camera. all you can hear is carbs sucking in air with the "bog" sound all the way to 7K rpms and its very loud. the 2-3 shift drops the rpms right at 4500 rpms, so i suspect its not a bog sound from too low of a rpm drop rather the carbs. when my son is nailing it around town i can easily hear him 1/2 a mile away the carbs are so loud and if he is coming my direction even further away than that.
