rev to 5500rpm and straight drop the clutch! Awesome launch rated by all.

Yea I had a b*tch of a time trying to get my manual off the line, would either be bog or heaps of spin (its also a ute so bit light in the back).

As for Icers comment not even 5500 is needed to get that awesome launch going for 1/2 a track.

With manuals every launch is different, hopefully I'll have this sorted in my ute soon with a launch assist from my tuner.

So far 3000, 3200, and 3500 have worked with tyres running 30 psi and slipping the clutch( stock clutch)

I launched at 3000 at my 1st outing and it wasn't enough. But I changed my t5 to t56 without changing my diff ratios. Will just have to get out and practise. Thanks for the replies

I had my first run on wednesday night and had trouble getting off the line with out lighting it up, actually I was still wheel spinning at half track. I ran in sport mode, sequential, tc on tc off 30 psi then 18 psi big burnout little burnout

the result was a bet run of 12.35 and worst run of 12.9 average runs were 12.6

the 12.35 we 18psi street tyres big burnout and sequential mode

If anyone has any tips for a auto ute please tell coz im not very happy with those times

Drag Run with a ZF6 Auto.

Check you Dyno sheet and find out what RPM your car makes Maximum power before it starts to drop away ( this is your shift point, Mine is 5800 RPM.)

If your on street tyres (13 psi)you dont need to do to much of a burn out as they operate best at around 60 deg ( Et's around 100 Deg).

every thing off Tc, A/c ect

easy burnout in 1st.

Stage at line and brake hard in second gear ( this is to over ride gearbox protection in first)

dont worry about trying to win the race if your just after your best time, the timer wont start until you break the light beam.

Stall to 1800 RPM or less if your brakes wont hold.

When the light turns green, put your gearbox infirst and as soon as the gear select shows 1 (First gear on your instrument cluster) GO, GO, GO.

Foot off the Brake and exalerate flat to the boards.

I dont have a shift light so I Watch the tacho and change to second just over 5800RPM.

Hold it flat to the boards and change to third just over 5800 rpm

Th ZF6 does over 200kmh in 3rd so you dont need to change to 4th, just keep it flat in 3rd and dont back off at all until you get the OTHER side of the finish line.

Then nice firm/hard braking to slow you down for the turnoff.

It Works for me....11.4 @ 123 Mph on street tyres. std unopened engine.

The gearbox protection override technic for first gear in a ZF6, was told to me by Lee Bloom ( Real Dyno Performance) 10 second FG, It allows full torque in first gear through the Trans.
