You can get a good 60' if you dump it making a bunch of power, thats a is a huge help. Thats different then guys like me, rob, and robZ being cam only. I was only making 415-425whp and cut 1.4s (1.43 best)
I know some guys put a fan under the car, or even have a duct hose off a fan they run to the bellhosing to blow air right in there. I don't trailoer the car and don't bring tool really, so just open the hood.

I've done both and I was a pro-dumper but after testing it I have found that by slipping it, yields a better 60'(for me atleast). I can come out at least 200-400 rpms higher with a slip.
I think the biggest reason on why it worked for me is because there wasn't any slop in the drivetrain. And on a lil tire (26") I didn't have much forgiveness on the sidewall.
Introducing massive wheel speed on a stationary object at 100% power is going to go up into a spin faster than say applying the same wheel speed at say 90% power. But either way you should have adequate IC and AS values.
Slicks can get away with a longer IC and lower AS. DR's need a short IC and a high AS due to a stiffer sidewall.

Mark do you have a 2 step in the car? I bet that with a 2 step to leave off of, you can dial the paunch RPM in so you can dump it and end up with the same results, without beating the **** out of the clutch so bad.
That's one thing that alot of guys are missing, you put a 2 step on, put your foot to the floor and dump it, 2 step disengages at the clutch release.... you play with that 2 step RPM until you get the car to leave as good as possible and you will see it pick up. And, it will do it CONSISTANTLY, something you're NOT going to do just trying ot go off a tach. Well, not if you're even 1/2 paying attention to the tree... ya can't really do both at the same time effectively.
Slipper clutch and a 2 step is by far the best for a race car. But, for a street car, or something you want to drive, a 2 step and slicks, will get it done. Still gonna break alot of **** doing that after a while/sooner or later, but it is what it is.

agree 100%. two step and a shift light are the two greatest cheap parts i have ever put on my car in 10 years

Stalled auto isn't gone get the MPG a t56 car dose. Or crusie as nice on the highway with your 4400 stall for 4 hours. Or over heat in traffic, with out a fan on your trans cooler
I love passing all the trailed auto (street) cars on the way to the track.

...yeah a double overdrive will help you guys some...but the cost of clutches is a non issue here...so maybe that balances out some...what does a slipper run again? haha 
also never had temps over 190 in stop in go ever with my 4000 and 90 degree summer days...
and cruising on the highway is no biggie with a lockup clutch...I can have a 3000 stall or 6000 stall as long as it is a lockup clutch it will be the same rpm...talking about driveability I heard that slipper is a no-no on the street...
I had to give you guys ****...
why not get a manual valve body auto so you can still have your shifting...look at the liberty, basically an auto with a clutch for the launch...ok I am done teasing back on topic, m6 launching....

did I just read that right, you said miles per gallon, better think about a cam with less overlap... ...yeah a double overdrive will help you guys some...but the cost of clutches is a non issue here...so maybe that balances out some...what does a slipper run again? haha

If ya want I can start busting YOUR ***** about running a 4ljunkie tranny... which go out at the whim of a hat.... unless you put an 80 in the car, then you don't have to worry about your od tranny crapping out.
Or, put a TH400/350 in the car, as I know either will go faster then you are now with the 4ljunkie.
No matter which side of the fence you are on there's good and bad.
