so how do you drag a C4 ZR1 ?

[xxxscimitarxxx]

Im asking because l will be taking my yellow 92 to an american car day on 30th may in UK at a drag strip .....shakespeare raceway

anyway my UK corvette club is organising the event for all vette owners who want to run....kind of trophy event too as this will be one of four event we are doing..........anyway

whats the best way to get a C4 ZR1 off the line......revs , clutch dump or no dump.........newbie strip drag racer age 51......:dontknow:......lol....never too old for a new career

one day soon lm going to buy some muscle thats got min 1000 hp and have a lot of fun .....this is just the beginning

I dump the clutch! I'm running 342rwhp so it's pretty much bone stock. But I've found with my car that dumping the clutch between 3500 to 4000 rpm's usually does the trick. Then shifting in 1st and 2nd gear at 6800 rpm's. And when you hit 3rd just mash that gas peddle to the floor and hang on. The drag strip is more sticky than the street. Once you find out where your cars sweet spot is at launches, you should be running between 13.05 and 12.9sec at around 112mph. Despite what some may say! Drag racing does take some skill. The time slips don't lie. They will tell you if your improving or not. You will get plenty of advice from others here. You will have a blast.:thumbsup: P.S don't ever wait for the green light. As soon as the last yellow light before the green starts to fade! Nail it.

do you have street tires ????if so go around the wet box .put the car in second gear for your burnout . i differ from rick alittle bit on the starting line and the first to second gear change .not to say his way wont work . i would put the starting line rpms at no higher than 2000 then let the clutch out fast but dont pop it .short shift 1st to second at 6000 then you can shift second to third at 6600-6800 rpm and go thru the lights in third . this proceedure is for if you have 3.45 rear gears (stk) if you have 4.10s then go thru in 4th . i have some vids on u tube that may help . just type in joeshmoe12301230 for all 11 vids . you can also go to rangers site for helpfull hints on drag strip proceedures . hope this helps and have fun but watch out drag racing can be addictive .ps please ck the condition of your 1/2 shaft u joints before going .breaking one of them will cause you to have to get towed home . the car will not move with only 1 1/2shaft .

also work the throttle down so that you are floored by 15 ft out dont slam it down as you will just blow the tires off the car

Both of Brads ZR-1's are bad to the bone. And are not totally stock. I know I've driven one of them. "SCARY". So the technique will be different. But it's all about practice. But Brads been at it longer than me. Not bad for a 55 year old man. Haha!

Brad, has given some great insight, but i feel the rpm's vary
with every vehicle, my car, headers, chip and corsa, 410's
i rev to 2700 rpm's as not to bog at start.
then....let her rip, tator chip.

where you on street tires????

[jonszr1]

did you go to the strip yet?????

[xxxscimitarxxx]

30th may..... UK not like US....cant find a strip round every corner....or l would be on one now

[jonszr1]

hehe , its 200 miles around my corner to the closest strip one way. really big corner . and driving on drag radials on mountain roads is a very wild deal .if you jerk the wheel at all ,you do the loop de loop .:mrgreen:

Shakespeare raceway? Did that used to be Long Marston? Went there a couple of times when I was involved with the drag racing team over there.

[xxxscimitarxxx]

i just checked and yes its long marston

[DaveK]

It was a nice track - good facilities for a UK drag venue. Probably even better now. Good luck with your track day, hope it's a great day for you and you have a lot of fun :thumbsup:

:sign10:

Had to laugh. That was me at my first (official) drag race in the Z. My reaction time was .7!! I barely got my rpm up and suddenly the light was green!:jawdrop: The stock C5 beside me jumped out about 2 car lengths ahead before I got the clutch out. But, I managed to turn in a 13.1 at 111mph on a stock 90...AND end ahead of the C5 by about two car lengths in spite of my napping at the starting line.:rolleyes:
