Back from a long day at the track......
Just got back from racing in Bradenton... Well - it was a long day...
I arrived at 9:15 AM at Scott's (C3 Shark Tank) house. From there we went to DeSoto Speedway.. Arriving there - we were told that Test & Tune would only be from 2 - 5 PM this Saturday because of a "Special Event"....
We decided to hang out at the track to wait for 2 PM.. At 1:30 I started the engine to warm it up... Luckily somebody nociced that my lower alternator bracket was broken... (Imagine if I would have raced with a broken bracket at 6400 RPM :eek: :eek: :eek: - the alternator could have broken off and done some serious damage)... As Scott described in his post - we had to go to Bradenton (Bubbaville) to get a replacement.. Well - after visiting several parts stores - we finally found one at Automotive Engineering - a local Speed Shop... So we went back to the track to make some runs... Everything seemed fine....until I actually did my first run...
This time I launched at 3000 RPM and the Drag Radials gripped absolutely great - no tire spin at all - pulling a almost unbelievable 60' time (1.678 :eek: :eek:) and I felt already in 11 second heaven... but.... wait... when I tried to shift into second gear... the gear wouldn't go in... After 3 tries - I finally got second gear in... (took about 3 - 4 seconds before the gear was in) ... same thing happened when shifting from 2 to 3... DAMN - with this 60' time - a 11 second run would have been very possible if the tranny would have shifted correctly... I thought that the tranny wouldn't go in gear because I tried to rip the gear in too quick and made another run to try again...trying to shift slower....
The second run - I launched at 2500 RPM and got a 1.756 60' time which wasn't bad either.....however - when trying to shift into second gear.... the same problem occured even though I was trying to shift very slow....... I just cruised to the end of the track - it wouldn't have made sense to continue...
I still wanted to try again... shifting even slower than on the second run...
The third run started out like the first 2 runs with a good 60' time (1.727)...
This time - I managed to shift into second gear very slowly (I also shifted at a lower RPM).... then I shifted into 3rd gear very slowly....... but when I shifted into 4th.... it wouldn't go into the gear... so I finished the run in 3rd gear... The ET was unbelievable considering my problems.. Here are the stats of my 3rd run:
60'..... 1.727
1/4 mile....12.697
mph........102.61 (well that's the speed in 3rd when hitting the rev limiter :jester)
Finally I got the right thought... that it might be the clutch linkage... My 68 has a mechanical clutch and it needs to be adjusted once in a while... I was so used to self adjusting hydraulic clutches so that I forgot that I had to adjust the clutch.... After adjusting the linkage - I made my last try...
This time I only launched at 2000 RPM which caused the slowest 60' time of the day (but still respectable) 1.813... This time - I shifted carefully (and slowly) through the gears and they actually went in!!! :eek: :eek:
I ended up running 12.408 @ 114.62 mph...
After that run - Scott had to leave to get some sleep.. (He works at night and I'm responsible for a lot of lost sleep)....
After that - I wanted to run again - knowing that the transmission was shifting fine now... This time I was100% sure that I would get into 11's just by shifting faster (ripping the gears in like I usually do).. Well - bad luck... It was already 5 PM and the track was shut down for a Special Event... I might try my luck at Moroso Speedway next Friday... I just hope that they won't inspect my car there.... because it wouldn't meet NHRA rules....
The day still ended on a positive note because:
1) NEW BEST ET (even though only approx. .1 faster than my prev. best)
2) NEW BEST MPH (114.62)
3) NEW BEST 60' time (1.678)
3) At the last run - the car felt like a rocket... I just lost some time shifting carefully and slow because of previous problems..

Congrats on the new best times. I am sure that you will get into the 11's very soon, hopefully next Friday. I will put mine up on the hoist this week to check the rear end, change the tranny fluid and get ready for maybe one more run. With my 15" 245's there is noway that I can even launch at 2000 rpm, I just spin. Last run I launched at 1500 and was able to keep the rear end sticking. There are 4 of us who have decided to autocross next year so I had better do some rear suspension work this winter as well (time to replace the Monroes and steel spring with composite and Bilsteins all around). :cheers:

But remember, mechanical clutches shift faster than hydraulic.

The greatest thing about track days is coping with problems that NEVER pop up when you are NOt at the track. :lol: :lol: Sounds like you are going to be back there at the first opportunity! :cheers:

Hey O.... sorry for your problems, but you are fairly new to this sport.
Give it some time, and get some more experience, and you'll be running where you want :yesnod:
The good part is now you have stories to tell us next week at the Tower Shops :lol: ... unless you go to Moroso.

Makes me want to get a set of drag radials. Good 60 foot times. I could probably be in the low 12s with those 60 foot times

every tenth on the 60' is worth about a tenth and a half on the top end :smash:

Re: Back from a long day at the track...... (GrandSportC3)
Your MPH says you can do it!
You might take a close look at your motor mounts. Often when you stick slicks or other sticky tires on something, you get a lot more movement of the engine/trans combo. Enough to put the clutch linkage and shft linkage in a bind if it hits on the tunnel.
I still use stock type with the interlocking tangs to limit ultimate movement. You may need a torque strap of some sort.
Good luck.....you brought it all home in one piece and that's a good thing!
Kind of like flying..... Any landing you can walk away from was a good one.....and if they can still use the airplane.....it was a GREAT one!
