Gday guys.

Went and had a run at the drag races at Western Sydney Intl Dragway tonight. Was a bit dissapointed with my times, but still had a great time, and earnt a bit of respect for the Micra along the way.

1st run. 16.865 @ 84.53 mph
R/T .160
60' 3.044
330' 7.569
660' 11.188
1000' 14.221

2nd run. 16.721 @ 84.20 mph
R/T -.111 (oops jumped the gun there:)
60' 3.035
330' 7.451
660' 11.096
1000' 14.133

Both runs were against a VL Commodore v8 which I beat off the line and stayed in front of. However his times were in the mid 15s? I think because the timing starts when your wheels move off the line and he was spinning on the spot for about 2 seconds.

3rd run. 16.336 @ 85.27 mph
R/T .276
60' 2.894
330' 7.212
660' 10.742
1000' 13.732

This run was against a Lancer GSR who ran a 13.579 and smashed me all the way.

I guess I was expecting in the mid 15s as per others who have done times. But then I thought that as I am currently running a std clutch, std flywheel, and std gear shifter, and I think others had JUNS fitted and better clutches and short shifters that this could make the difference. So i think these things will be next on the wish list. Plus I also raced with everything in the car. It was exactly the same as it is on the road. If I can find some pics I will post them up.

Cheers guys.

Sounds like you had a good run Gareth.

"Red Dragon" might not have been the fastest car on the day but I am sure you were heaps faster that any micra close to standard.... And at least it looked like you were faster than that commodore.. ;)

I think Ghetto and others in WA had a dragstrip run in their fairly standard cars recently ?? but I can't remember what their results were...

I am sure the upgrades you are planning will help you along a bit next time.

Thanks Makes. It may also be that I need to work on things like gear changes etc. The car went great off the line, but did run out of puff towards the end. But in the end I had great fun

By the way Makes. What was the name of the people you found in Sydney that supply the JUN flywheel? I wouldn't mind contacting them re availablility, and price:)

Hi Gareth,

The supplier was : www.perfectrun.com.au

They will be able to help you out. The Jun flywheel cost me around $520 including postage.

Yes, you will be more experienced next time... as you got more used to drag racing your times where obviously coming down with each run.

Perhaps you will have the chance to do some hillclimbs or sprints sometime ?. I personally find these more interesting and exciting than drag racing.

Hey Mate,

The strip is awesome fun and its a good experience..hard to be consistant isn't it? Good to see you get out there though and give it a shot.
Can't wait to get back out when I get my car back.

What were you launching at? I found that around 3500-4000 was good on the track (way stickier than the road)
Did you let your tyre pressures down a bit? I was running about 20psi.
Did you bag em up at the line? Usually a burnout of about 4-5 seconds is good.
What brand tyres you have? Are they soft/hard/cheapies? I did my 15.5 on some korean NanKangs which were HARD as..still they did pretty well.

Looks like you have some trouble getting off the line as your 0-60ft times are pretty high. I'd work on your launches..good launch should see you into the high 15s..

I had no lightweight flywheel or shortshift and was running 5psi on this run..you should be pretty capable.

I think you are right Evade. I actually didn't realise that the time started when you left the line to start with and was trying to go right on green which is why I jumped the gun on my second run:) And also why the Commodore ran faster times even though I beat him both times. Because of this I don't know what amount of revs I had up before leaving the line, next time I will pay more attention to this rather than the lights:).

Also my tyre pressure was not reduced, they were still at there normal pressure, next time I will let some air out. I didn't do a burn out at the start either, Don't think I will do this next time:) And my tyres are just some cheap korean Marshall ones. They seem ok but are not great quality ones.

Oh well it was a great experience. Thanks for your tips mate. So I will definatley work on my launches rather than reaction times. Gees makes me want to go and have a run right now. Oh well I might go again in a few weeks:)

I personally don't see the point in driving 400m as fast as you can - especailly with the mechanical strain it places on everything.

Outright track racing, hillcimbs, etc are much more fun and better value for the money - not to mention less stressful on the car as well!

Just my opinions....

But still, its fun to see how quick it is and its great to see pretty stock 1.3L micras challenging what a 2.0L pulsar can do and not to mention giving the big v6 commodores and i6 falcons a bloody good run for their money!!!

Good on you Gareth. Sounds like you'll nail it next time, yeah it must be different to get used to.

I'm envious. I really need to get my car there sometime. But because there are no dragstrips here, I'd hate to drive to Sydney and have to get it towed home ! :)

Ouch!! NotAnotherSSS that hurts:) Seeing as my "pretty close to stock 1.3l micra" has had a turbo conversion:)

I think I'll put those times down to my lack of experience. Hey I'd never even been to a drag meet, let alone raced in one until the other nite:)

Thanks Cisco. Definatley next time I should run in the 15s somewhere, at least that's what I expect to do:) It would be great to get a few Micras there some time.

I don't see how any of those are anywhere NEAR less stressful on the car?

I've been on the track and on the dragstrip..and let me tell you..the track is WAY more stresful than a dragstrip.

evade - it really would depend on how you set the car up and what parts you use. for a pretty much stock and road going car, well the odd non-professional race against the clock trackwork is going to be much, much nicer on the car than the sudden launching and high rpm gearchanges associated with straight line drags.

Most stock gearboxes and diffs arent designed for the launching and style of gearchanges a drag usually demands. Especially not a micra gearbox!

For example, on the average sprint around queensland raceway, the brakes are going to be the most stressed. (Of course then you factor in engine wear, but engine wear happens and there isnt really jack all you can do about so i don't believe its a relevant subject....)

I'll try not to steal this thread now. :)

Gareth - what you talking about brother? you telling me the SLX didnt come with a turbo stock!?!?!? =P </dodgey cover-up>

huh? This is interesting TOM, i thought that you'd be trying to get to the end of the first straight as quickly as possible. In which case you'd be driving it as hard (from a standing start) as you would on a drag strip???

With one exception matty - you're already moving. Already there is less stress on the gearbox internals, differential, CV joints and therefore clutch.

Would depend highly on the track too - I know QR isnt THAT hard on the car.

I just realised I totally forgot hill climbs - I don't know what I was thinking but hill climbs are definately high stress events... My mistake on that one.

Its like comparing apples with oranges

Sure dragging does place immense stress on the car... but 99% of that stress is placed on the driveline, engine and mounts not so much the entire car.

Trackwork is demanding on the entire car. Think of the amount of twisting forces from quickly changing directions. Everytime you do that it warps the chassis albeit minutely. The suspension also gets a hell of a lot more of a workout too. Brakes, don't even start me on them!! The driveline cops a huge amount of abuse too, but its mostly just constant use, not the shocking forces that are involved in high rpm launches.

So I agree partly with NotanotherSSS and also with you Evade, but its entirely different scenario's so you can't compare.

And the stresses experienced on the Bathurst track are a fair bit different to those experienced on Queensland Raceway.

I should have known this would have gone no-where haha

I've had a long, bad & frustrating day at work. :(

Thats why I said apples and oranges...

But in general its my opinion that trackwork does more overall damage.

Not to say that drag racing isn't even a little bit fun though... But the twisties is where its at!!

Hmmm actually I wouldnt be surpised if most cars get more of a shake up on your average city street than they would a nice track :p

Thats if the roads and highways i travelled on today say anything about them. My poor dash has developed even more rattles :(

Track is the hardest on engines. Persistent high revs.

Drags is the hardest on drivetrains - jolt - impulse.

Track also tests chassis/brakes/suspension to the max.

Overall excluding drivetrain, track wins hands down as a harder overall strain. But drags will always tax your drivetrain harder than anything..

Interesting comments and all correct.
To me a cars performance is the complete packaging.
Not only the go fast bits but the braking, handling and durability and the looks.
HIgh powered cars that handle and corner like druken cows,guzzle large amounts of gas are not very interesting.
Most four wheel drives turn me right off and specially those idiots who put even larger wheels on thus upping the centre of gravity and making them even more unstable.
Pity the cops instead of picking on young people all the time did not get stuck into the these vehicles.
Sorry got off the subject a bit.

Your resident Tassie old fart hoon.
I am coming Whitey. Did you sleep well without me in the back seat?

Funny you mention the 4x4 bit - most people who modify their 4x4's in that manner are usually just looking to get that little bit extra ground clearance. Sometimes there's only a few millimeters of clearence between your fuel tank and those jagged rocks on the track beneath you.

But of course you do get the wankers who never touch anything more than a gutter. The same goes for some people in their small cars though - install a full cage, harness and racing seats and never drive within 400m of a location where it is legal to drive the car hard enough to warrent the use of the saftey crap they installed...

Too much digression for the morning!

I think i've spent too long in the sr20de pulsar world where a bad gearchange can mean life or death to your motor and gearbox...
