don't forget to let your tyres down, about 20 psi should do it. 14.8 with traction.

Be very careful with the launch with a stock diff. Have you ever walked on a drag strip, particularly the start? It's that sticky with traction compound, your feet stick to the ground. Side step the clutch and the weakest link will let go.

Realistically at a street meet the tracks not going to be that sticky, I used to have less traction on street tyres at the track than on the street in my twincam! It will still hook up if your doing it right and to be honest, it's not going to cause you much more grief than launching hard at a set of traffic lights.

Apparently a drag strip is like a normal road on a street meet....

Sorry, I should have also said it depends on the weather, the track prep (will be different if a big event has just been run etc), your tyres, launch etc

 

I didn't see what track was mentioned but down south I get more grip on ballarats 1/8th mile track (that's normally used as an airstrip) than I do at Calder parks street meets. If it were a big event the track prep would have me sticking to the ground as red mentioned and snapping axles or tearing up 1st gear in my wagon. And that's in a slow car.

 

Sorry if I was misunderstood.

 

Ride the clutch a bit off the line to save the diff, it's the shock loading that will kill it. Or too much power for that matter.

I was tought long ago a great way to stage in a manual car, pull the handbrake on once staged keeping your thumb on the button, bring the revs up and take up the clutch whilst using the handbrake to keep you from moving, once the lights come down you release the clutch and brake and get into it with no shock loading to kill the rear end... Just your clutch :(

 

I will stop rambling, go have fun and get on the track!

never heard about the handbrake job but yeah

ill let you know how i go on wednesday

with street tyres and an easy launch to preserve diff and uni's.. ill go with a 15.2

 

if your feeling game, id go a 14.9.. if it survives the launch

yeah if had the diff in 2 of my ke10s and ive gave it the shock treatment over 50 times and she hasnt let go yet so hopfully it wont let go on wednesday ill let you guys know how i go

ahh genius. Trev I've read a bunch of threads this morning with you quoting people and it's funny shit.

 

I vote we dub thee "master of paraphrase"

i recall when we took a mates rx7 series 1 12a turbo to the drag strip, first drag of the night, he got a little carried away...with his new semi slicks and a 8000rpm launch.

 

both axels snapped.

 

long ride home in the tow truck.

 

little red spririt is getting 15's or so in his 20V ae71, so i would expect much the same from your car.

how long is a piece of string?

-twice half its length.

Matty also has a decent diff that is not locked.

hey guys ran the ke down at the creek last wednesday best i could get was a 15.6 at 144km/h and thats with traction i did 4 runs and they where all between 15.8 and 15.6 what else could i do to get it down!

Put a decent diff in in and go for broke.

Better tyres.. Hasn't that thing got 12"ers on it?

yeah i don't think its the diff thats loosing time i think it just needs more power
