What's she weighing in at these days?

Nice time Joe and killer 60' :thumbs:

I actually left my garage with a light jacket...as I rolled up the windows, went back in for my rarely used winter coat! We florida folks aren't used to the first digit of our temp starting with a 4...49 as I left my house.:lol:



Thanks! I am very happy with the 60's. That accelerate into the launch trick that Robz told me about is really the key.

You cannot let your car bog or it's a 1.8 60 foot. On those 1.445 launches the car never went below 4800 RPM throughout the launch process.

I have only 414 tq so I have to spin the engine. I think Z06's and Zr1's with 100+ more ft lbs are able to bog more than me (based on listening to their launches).

I think it's been proven that the stock z06 clutch will not handle a 6700 rpm launch no doubt given the much higher torque of the 427.

I wonder if a Zr1 would handle a 6700 launch with its dual clutch....

I did a few things.

1) Removed the clutch spring. Well, Joe removed it the first time we met at PBIR, but ya-it's gone.
2) Removed the inspection plates on the bellhousing.
The problem with the corvette hydraulics is that the clutch dust has nowhere to go when it is generated and it then penetrates the vulnerable slave cylinder which is why the fluid turns black.
To assist the clutch dust from exiting, I removed the 2 plastic inspection ports on the lower sides of the bellhousing. I did this a few months ago and my clutch fluid has been remarkably clean ever since. I still do the fluid swap, but what used to take 3 or 4 cycles of clean fluid to 'repair', now only take 1 cycle.
3) My burnouts are now only 3-4 seconds. I used to do longer smokier burnouts to get my Toyo drag radials hot, but these Mickeys don't take much to get them ready.

I also swap the fluid before and after the drag strip as Joe recommended to me awhile ago. I don't expect to get 450+ passes on it, but I'm knocking on the door to the 150+ pass, 70+ of which have been with the cam installed.

Hope that helps.

Big thanks again to Joe for his invaluable information he has so graciously shared with me. Thanks buddy :cheers:

I do the Ranger method before and after each event religiously since new. The fluid is pretty much always clean, even yesterday evening after those events.

Removed pedal spring as soon as I put in a cam. It was sticking to the floor after the cam (but not with only bolt ons).

I don't think my car has anything plugging the inspection ports on the bell housing, I've seen tracks of clutch dust on the bell housing.

Check out the clutch dust on the video! My buddy said it looks like a pro stocker belching out dust. :lol:

It's interesting you say that Joe--as I've had my car bog multiple times and I still get high 1.5 60fts. If I want a low 1.5, I have to keep the rpms up but these Mickeys really stick and cause my rpms to bog down to 3500 on a few of my passes.

You say you only have 414tq though? I thought you made more for some reason. Perhaps its the additional torque that lets me "recover" from the bogged launch?

That's in street trim though right? Surely you're not pushing 3200lbs with the drag pack and no passenger seat. :eek:

The only other difference in our cars are the gears, right Joe? I make a hair more power, and you have a better gear for the 1/4 mile. My mph is a little higher in the 1/8 than yours, but you obviously come on strong by the big end. I'd love to race heads up one day-talk about a drivers race! :steering:

Oh, and :lol: at you having that screwdriver.

:lol: That is pretty interesting actually. You are/were my Mr. Miyagi and I learned from your teaching and we run identical times? :rofl: Awesome

I only need another ~.1 to take the top spot for LS3 internal modification and all the guys ahead of me have way more mods than I do. I just need a nice cool day

From my experience of swapping from 3.42 to 4.10 gears at my lesser power levels it was worth ~13/7

Though the gears are actually worth 2-3 tenths ET, which fwiw turbovic has a non-z51 trans that held him to a 1.61 60'

Yes you do. You've come a long way in a short period of time. One cool day with good track prep and you'd have it. Sorry I didn't think to call you yesterday, you're a little far, but man, it was wide open track and negative DA in the sunshine all day. That's about as rare as hen's teeth here!
