Out of interest, how do you perform a successful launch when doing a 1/4 mile run? What revs should you be running at and is it ok to dump the clutch or will you be sweeping the gearbox off the floor?

The Racelogic Launch Control function is an excellent aid to quick standing starts. It does need to be set up properly however!

 

I'm going to be at the Pod this year when I get my Zed back on the road and will be able to demonstrate how good this really is.. :cool:

 

This feature will only work on manwell cars

i seem to find, you want it just below the rpm that the tubs kick in otherwise if there already spooled up you have more chance of lighting up the tyres up and taking off up the strip sideways when you dump the clutch!

 

or is that just me?

Revs required depend on which track you are running, how its prepared, ambient temp etc.

Car factors also affect launch revs. What tyres, how much RWP you have. What clutch you have etc.

The size of your wallet is also an important consideration.

Sun 13 Aug is round 5 of the Z Club Drag Challenge. A few of us will be there.Come along for some free advice n fun

Here is an example. Three weeks ago at da Pod on a Pro Track with virtually perfect weather conditions I was launching visciously at 5500 revs and dumping the clutch and I was still dropping revs a touch. :(

On a poorer track with only road tyres I might find 3500 was plenty.

Like many things in life it looks easy but it aint.

Two and a half years after starting 1/4 mile runs and I still dont always get it right.
