Launching 0-400M

[Boostn]

Tried a search.

How are people launching there cars off the line?

I have a g6et and can't manage a good launch without lighting up the rears

I'm interested also

3000rpm =burnout 2000rpm= bog down ... Who's got a sub 2 second 60 footer in a stock fg and how'd you do it!!!

[lightning strike bf]

Try 2500 or some were in between not that I drive one but that's we're I'd start or start at idle 3 quter pedal then full and take of on last yellow or in between last to some times u have to run a red to see exactly were to hit it in the yellow will help reaction time heaps wen u get it sorted

[ratter]

why back off early at 400 mtrs, why not go the full 1/4 mile

[Lennox]

Come on you must be able to give some useful advice mate or do u just tune em not drive em

Same boat as you Boostn.

Have had a couple of decent launches, but mostly I bog down/slow to spool.

Still at the stage though where I have zero idea what I'm doing and fluffing my way each run.

Need to start taking note of what I try differently each time and working out what works and what doesn't.

Really does show you how important getting off the line and the 60' is though.

edit: think my best was a 1.9 (will need to check sheets) - usually around 2.2 (stocker) :(

Might lose the race in the extra 2.3m?

Stall it up on the brake and get some drag radials like Mickey Thompson et streets. They make a huge difference.

Unless the track is in perfect prep (so really only ANDRA events like T&T and FTF) your going to struggle to net consistent sub 2 sec 60'fts on street tyres.

My best effort on a street tyre (245/40/18) was at such an event and I was able to net a 1.738

Failing a good prepped track you'll need the following:-

Built Tail shaft

MT 275/40/17 radials ( or similar)

8 - 10 psi of boost

Now I found the best method of launching was letting the car tell you so, what I mean by this is that you build your stall on the footbrake and you'll 1st start to hear the spool and then once the car feel like it about to move or actually does start to move this is when you go.

If you use this method I assure you, you will need 1.6's or lower but in saying that you'll need to make sure you've also willing for something to break.

Practice and patience is the key here, you may fell like your stalling for ages when in fact your only stalling for 2 - 3 secs.

Build your stall slowly and for as long as it takes to get either your desired boost or my method of waiting for the car to slightly move.

Good luck!

The part about accepting the risk of something breaking is what lets me down on the launch. 1.9 is the best 60' I've ever done but that was 100,000km after my PB and ZF was slipping down the track robbing me of mph big time.

Ironically, I broke the flex plate loose that night..."just one more run"
