I hadda do it .. really!

Mac, don't forget to put your shoes on first.

You guys do have shoes in Ok, right?

OK, H/C/I now were talkin! 

Please don't take this the wrong way as I'm not trying to be argumentative, just a bit confused.  Do you already have some work done to this car?  187 out of an early non-z06 c5 just doesn't seem quite right to me, especially one running high 13's.  I know AZ is hot and that track has a bit of altitude but it just doesn't jive in my head.  Granted I have been out of the car game for a while now so the memory is a bit fuzzy.

Ya .. the 13's I run at Speedworld would probably be high 12's at ATCO or some other decent tracks.
It's not that it's just hot .. the startin line is slicker than any street I've cut loose on.
I ran a 13.98 with outside air temp at 113 degrees -evil grin- ..spinnin the tires for a good 30 feet out, and spinnin a bit again when I hit 2nd.

The guys that are hookin up there are runnin 14" slicks and alla go fast toys.

Trap speed is right at 100mph .. and she's hits 3rd gear about the first mph lite.

3.15's and 26" dia tires ..I need 3.70's at least to use all of 3rd gear .. forget 4th all together.
To put the extra torque to the ground is another project ..
..tubs, stickier, bigger tires ..
..I hear there's a mod to use 15" wheels so I can hang 'real' racin tars out the back
-evil grin-
.. man ..
..I would love to back half the car, 4-link a Dana under there, and stuff 14x32's up under there ..

I mean.

You leavin the TC on and just mashing it, or do you turn it off and use your left foot on the brake to load the converter?

[Grayeagle]

TC on, foot onna brake..no loading the converter at all.

I prolly should load it up a little to reduce the wheelspin
(hopefully ..street tires are pretty much a waste at hookin up unless they're drag radials or better on these cars I have read)

I've come off some stoplights at wide open throttle givin the vette all she's worth and not even a chirp some late nights and no traction control warnings at all .. after the tires are warmed up from a coupla miles of driving.

Speedworld is like a slick parkin lot on cold tires
Still fun to play . . still a second faster than most mustangs I see there -evil grin-

Just for chits and giggles give this a try.  Turn off your traction control, left foot on the brake, load the converter to the RPM just before the back tires start spinning.  On the third yellow lift off brake foot, keep gas foot where it is, the nose of the car will obviously come up just a bit and as you feel the nose start coming back down ROLL on the power.  Practice it in an empty parking lot or something first to get the feel for it and the timing down.  This is by far the most effective way I have found to launch, and although my car certainly doesn't compare to a Vette, it did come from the factory with 345 ft/lbs so it takes some finesse to get out of the hole quick.

Geary .. dood.

Great description of how to feather off the line.

Coupla things you may or may not know about my Vette .. with traction control off, it goes a tenth slower.
Gettin up on the converter, it goes just under a tenth slower.
It's just how she works at Speedworld.
 ..and..
I 'like' just punchin it

(remembers featherin it when the steering hit the lock as the Duster got all the way sideways in 2nd gear ..and ridin it till she hooked, then jammin 3rd and doin the same ..back when it was a 4-gear on street tires, scared the wife no end ..pure tire smokin fun

I will set the car up for doin just that ..will take awhile.
I bracket raced for a long time -decades-.. and street raced for even longer
(still remember the first street race I won like it was yesterday, 1968)
Got invited to the Bracket Finals 4 years in a row runnin for LACR long ago.

I am a gearhead from wayback ..
I can still tune a tunnel-ram w/two fours to come off idle and bend yer teeth back in an automatic car
.. only 'bog' will be time it takes for the tires to hook.

Alla gee-whiz formula's and tuner-talk about CFM required per cubic inch
..my motors were always 'over-carbuerated'
..would still come right off idle and wing to redline without missin a beat
..pull so hard they'd scare wimmens and chilluns
..too much is almost enough ..always.
