Nice Simon,

looks like a bit of a short shift from 4th to 5th. Nice result.

Next, will well see what it does on a track with corners?

Cheers

Tim

Not sure John, but I am back at work anyway so it will be a no go for me.

I am hearing you about it being prepped properly after the big meets. My front wheels actually skated on the last run, mid track, before I called it quits. The track was definitely not prepped right.

I tried different things on the night (trying some of the advice John & yourself gave me ). It was a 5.5k launch, I shifted at 7k 1st to 4th and just after 6k into 5th. I did run a 12.38 @ 109 on my first run though, shifting at 7 the whole way. I just could not get the car to launch like I have been able to before down there.

Shifting later in 1st to 4th and earlier into 5th did feel better though, although I could not day it is quicker due to the track conditions.

Cheers Dave
I have every intention of doing so Tim

You should see if you can come up for the Jacks Hill climbs or a night at Barbagello Tim. NO LIMIT EVENTS, they are doing a Collie day too this year.

Great work Simon! 109 is much more like your power!

12.3 is also a really good time. 1.8 is great to.

Good work, man. You need to get a dedicated race car for all the event in 2012.

Ha ha ha, I had forgotten about that last shot . As for your comment before Geoff in regards to racecar, I have been talking to Neil about Robbys old hatch. Funds are a little tight at the moment as I need to get the 2.35 going, but I hope by Feb / March to get it. The Mrs is not too keen though

Heya Simon,

So you actually shift before redline when at the drags?

Any tips for me when i go down next week? The last time i went i just blipped the throttle to 4k and let the clutch out really quickly for the launch....and shifted at redline in every gear....also DCCD set to full rear...

This was only a few weeks after owning the car with really bad tyres...got a mid to high 13 i think from memory...

Don't mean to derail your thread but you look like you know how to launch!

The track will be well prepped, so you should get away with leaving your tyre pressures where they are. But if you find yourself getting wheel spin of the line, take out 1-2 psi of all 4 wheels, until you get it to hook up right off the line. Don't go any lower that about 26 psi though & pump them up at a servo as soon as you can on your way home.

I went down to about 25 lb last Wed and got a bit of track skate mid track (slight left / right slide movement), so be careful driving once you have let them down.

Because its well prepped, you should be able to launch harder than 4 k, but work your way up to it. You should be aiming for 5.5 to 6 k launches & from previous experience a 1.9X 60 ft should be attainable. What I have found is that every .1 of a second on the 60 ft time is around .2 of a second on the 400m time. You do need to launch them hard, but do it carefully.

I don't have DCCD, but I was there when a guy was using it one night. Believe it or not he got a better time by leaving it in Auto, but this may have been a coincidence.

Only try to make a single change at a time (tyre pressures), if you start changing too much in one go (tyre pressures & launch rpm) you might not be able to see what has actually increased / decreased your time.

One more thing is that while it is fun to race against the car next to you, the reaction time does not count in your 400m run. If you are only going down to get a good time, you can relax a bit more on the line and launch after the next to you has. This way you can pay more attention to your launch rpm, unless you have launch control?

Last thing I would say is, as a start point for your first run, tyre pressures at 30 lb, DCCD in auto & launch at 5k. Hope that is of some use, if you want to ask any other questions, feel free to mate

Wow thanks mate! Very detailed reply....

Give give it all a shot and let you know how i go!
