A scratch my head moment! - ZR-1 Net Registry Forums

rhipsher · 10-17-2010

Well I just changed my rear ujoints out for new series 1350 spicers and changed all the fluids with fresh getting everything ready for the Texas BBQ. So early this morning I take it out for another balls out top speed run which I havent done in 2 years. Since I'd done all the suspension stuff/new tires everything balanced Spec stage 3+ clutch blah blah blah! So did it and car runs freaken great and like always runs right up to 179mph and handles smooth as glass. But while I was at light spead I looked at where my tac was. Last time at the exact same speed I was at about 7000 to 7100 rpm's. This time it was reading 8000 rpm's.

No doubt my tac is off but what would cause it to go out of calibration that much? Also my gamin GPS said 181 mph. Ah! Whats the difference 179 or 181. At that speed who cares.

I've read some things about a capacitor going bad in the cluster and causing the tach to read high. The write-up stated that the original capacitors dry out or something and have to be replaced. That's all I know.

Where in the world are you able to that fast??? The roads around here (SoCal) are wal to wall Camrys and SUV's making a speed run like that out of the question. Color me jealous.

Rick you are certifiably nuts...but anyway...Id just average the two and you get 180! Lower that car and you will get over 180.

Kevin · 10-18-2010

taking a picture at 180...you've got bigger balls then i do my friend. I was trying not to **** myself, you're snapping pics

rhipsher · 10-18-2010

Wow wow wow! Guy's! Yes Ryan I may be nut's but I can't be the only one who's ever topped their Z out. Although I'm starting to feel like I'm the only one. And Kevin there's no way in hell I would ever take my hands off that steering wheel to snap a picture at that speed. Not even I am that crazy. That photo was a frame out off a video I made with a video camera strapped to the steering column. The video is has been floating around the site for a couple of years now.
There's a huge difference in going down the drag strip for a few seconds and hitting maybe 120mph and really hauling the mail at about 180. You outta try it some time. It will make your hair stand on end.

I know there is more then two of us here who have begun life.

If I get to 150 I better be airborne! haha, maybe once I sort out my little vibration. I think I have a tire out of balance too. What I worry most about though isnt that I will crash ( I should) it is that I will go to jail, lose my clearance and my job all over the thril of speed. I have to say when I was flying a real jet and not the robot I am now, i got that thrill every day. Now it does take a quick blast in the ZR to quench my thirst, but 180...not until I get on an oval.

I'm curious how long (miles) it took to get up to 180.
My guess with shut down you would need at least
4-5 miles of straight smooth road. Where?

you're looking at a minimum of 5 miles to get to 180 on a stock car
