Welp...2 steps forward, one step back. Again.

I've been waiting to mention that I've apparently found a little more power in the car recently. I was hoping today's trip to the track would substantiate that suspicion.

It did....sort'a...in a way.

The car's driving through the clutch again pretty badly--which means it definitely picked up power, but (as seems to be the norm for this damned thing) I can't fully quantify it on the timeslips...HOWEVER I CAN say this much...how many 4000+ lb cars do you know of that can pick up <span style="font-weight: bold"><span style="text-decoration: underline">TWENTY SIX</span></span> MPH on the back half with a slipping clutch??? (1st pass--picked up 23+ on the back half on the 2nd run--with the clutch still slipping like hell)

Check out the slips below (left lane # 105 on both runs):




Both passes were with stone cold tires--was paranoid about breaking the 12 bolt again so I didn't want the car to dead-hook. As it turns out, the clutch slipped badly enough that the car did dead-hook, but the 60' times were dismal. (For comparisons sake, the first time to the track last year it ran a 1.76' 60' time on a very soft launch and ran a 7.74 @ 90.2 mph)

I launched the car both times at 2500 rpm and it never even lifted the front end either time. I launched, rolled out a few feet and matted it, caught the shift light and grabbed the gears and the car rode the clutch until the top of 3rd when all of a sudden it grabbed and the front end hiked up. Both times when I grabbed 4th the front end came down but just at the top of the gear the clutch grabbed and the front end hiked up again.

I'll get pics &amp; video uploaded later, but there's really not much to see--just one rather embarrassing 13 second pass and a 12.25 pass.

So, it's smoked another clutch. At least it didn't $hit parts out on the track. [img]<<GRAEMLIN_URL>>/rolleyes.gif[/img]

Time for clutch #3...or a 400 Turbo (I'm rrrrrreeeeeeaaaaaaaaaalllllllllllllyyyyyyy getting tired of dicking with this damned manual trans setup).

More later.

Eric, Just my two cents, on your issue. Ninty percent of the cars that run a the strip . Are automatics. Eazyer on the drivetrain and more consistent times. I spend alot a time alot at alot of tracks and I see what guys are using. I run a turbo 400 with a automatic valve body. With a higher shift point, then stock. All I do is put the car in third gear, and put the pedal to the floor. Look what all the new COPO camaros come with from the factory? BBBenny

Absolutely agree -- I've run turbo 350 and 400s ... and as indicated, much easier on the drivetrain. Or you could run a beefed glide -- two speeds ... fast and faster. TAZ
