Articals or links for drag racing tech help.
Maybe the powers of this web site can chime in ?


Lots of new blood coming in to vw drag racing now ,there is aways something ,they are looking for help with .

Tech idea's, shocks , drag suspension , wheels , tyre's, race car wiring , fuel tech , engine tech , Carbs , turbo sizes ,Any thing for racing a vw , ect

Get the idea

Dak-A-Tak ·

42 people read this , so know one thinks it's a good idea or would like a place to look up tech stuff.
Well ! I'll go back , under my rock .
Unless people comment , nothing will happen .

HappyDaze ·

Gee.......a whole day, and nothing's been done! I suppose it took a while to build Rome, though, didn't it?

I think it is a brilliant idea. It is funny how each generation has to relearn everything that the old timers have already done for years. Dave Kawell and I talked about this awhile back . Think about all the time and effort people like Dave Butler and the other guys over there have invested , it seems smart to tap that resource. Something as simple as adjusting valves when you have not done it before would make a good article, let alone setting up a chassis for drag race use. Again, great idea, Mike McCarthy

Pete the CLA already has this function avaliable.Although you dont need a computer,you ring Dangerous,Craig,Westie,MattB,Macca,Ritchie or yourself.Problem solved and most of people i have spoken about are not selling parts just labour and years of experience.Good idea though but as long as i don't loose my phone i'm good,but im sure. it will help some

essex ·

I think this is a good idea Peter, don't go under a rock.
cheers

fast68 ·

Great idea!

Turbo54 ·

Nice idea although it is also nice earning by mistakes and figuring progress out. Much more rewarding that was. I saw something recently that said 'custom doesn't come in a box'.
That sums it up perfectly.

I think it is a great idea especially for those into drags rather than a street car setup.

Maybe you can change it to a 'Poll' type thread and then it's easy for people (lazy bastards) to vote.

mactaylor ·

yeah sounds like a great idea im in!

christopher ·

Great idea

Hi

I think its a good idea.

My son is a member of the R31 Skyline club, they have an excellent wiki technical page http://wiki.r31skylineclub.com/index.php?title=Main_Page As I'm the one that does most of the spanner work on his R31 I find it really useful.

Maybe something along those lines. Some of Joels how too post would be good, get rid of irrelevant posts etc

Steve

Gracey ·

Yep, top idea, bring it on!!

whathaveidone ·

I think its a great idea. I could do with a bit of a helping hand at the moment!!!!!

1916baja ·

Top idea, Would probably save Dave and I harassing Mr butler every time we can't figure something out!

FROSTY ·

I need all the help I can get too!!!

Dak-A-Tak ·

I'm not trying to stand on people's toe's or vw work shops or business .The vw drag car project is a huge thing to take on .
I notice in lots of posts that people ask each other for help or want information regarding tech stuff .
My comment about under my rock , was about getting people typing after I looked at the user's names on that period .

We have many great minds on here , that have there own skills or knowledge on vw drag racing or where to find it that part , so way not combine together.

I'm sure we could design something , any idea's?

Stanley ·

There's a country buggy tech section so why not have a drag tech section....bring it on

westi ·

closed,who jumped on who's toes.

westi ·

why is it a closed topic.
i love black label alcohol.
black label forums?.is it to naughty or something.
what's the deal bannana peel.

barls ·

if it was closed would you of been able to reply to it????
its been moved and a redirection has been left where it was. try looking closer

westi ·

found it.
me not so smart u know.

whathaveidone ·

So haw do we get this thing started??????

dangerous ·

Moderators please make this to become a "sticky" in the dragracing section.

LIFE IN THE LOW LANE ·

If you have a topic that should be pinned in a drag tech section post it up so those fountains of knowledge on here can reply with an answer and it'll be easy to find!!

humpty ·

Still nothing.... Mods please get onto this great idea... Aussie drag racing dubbers need this resource!

barls ·

Mate it's not the mods or admins that create new sections but the owner ie Andrew. Maybe you should contact him and point this out to him.
Alternatively if you want to start a thread on it I can pin it in the drag section

vw54 ·

I have moved it and made sticky into Drag Section

So ask away

andrewmurphy ·

I'll get started......
Section 4.9.7 Flywheel shields - states that vw NA running faster than 11.00 can use a ballistic blanket 'MEETING' SFI 4.1.
There is a guy here in Brisbane that makes ballistic blankets but they are not 'CERTIFIED' to SFI 4.1.
What do you guys run? If it's a blanket, how do you get it passed through tech?
I don't want to put.a 6mm shield around my bell housing.

dangerous ·

There is an SFI standard 4.1 for 'flexible' blankets, and also a 4.1 standard for 'trans shields'.

http://www.sfifoundation.com/drag-racing/

There are plenty of trans blankets available out there for other types of gearboxes,
that meet the SFI 4.1 standard.

http://www.sfifoundation.com/wp-content/pdfs/manufacturers/4.1%20Manufacturers%20List%20(flexible%20type).pdf

If the local manufacturer can make a trans blanket to SFI 4.1 'Flexible', then that will be perfectly acceptable by ANDRA.

Simples!

dangerous ·

Here is the standard required:

LIFE IN THE LOW LANE ·

What is the minimum length rear wheel studs have to be? Don't have an andra book with me sorry!!

dangerous ·

The rule book says you need a minimum thread engagement of one 'diameter' within the (hex part of the) nut.
So a 1/2" diameter thread will need 1/2 " length of thread engagement within the nut.
Cars 10.99 and quicker must have open ended nuts,
so that the engagement is visible.

I've got a simple little tip for a drag car.
OK then, two! 😂

1. Always put a battery cut-off switch within "really-fast-hand-swipe" of the steering wheel. Always. As your hand flails wildly in front of your great big huge goggle eyes at 100-and-lots, your fingers can flick out and kill the damn thing before it kills you! In addition to the ANDRA required external switch is easy to do.

2. You get vibration in the water box. Sometimes it can upset the float level and stall the car when you jerk forward and the slicks bite hard. While it's sitting there quietly, you notice you can't hear the pump whirring. Lucky you put all the relays and fuses, with spares, right on the tunnel within easy reach to change the fuse so the pump works again. So you can start it. So you can stage. So you can win and do it all again.

😁

Nice tips there Dave....

andrewmurphy ·

Anyone else received the new ANDRA rule book? They have changed some of the super sedan rules....

vw54 ·

found it. me not so smart u know.

BUT u can weld 😘😘

Hmmm, strange that. I didn't realise the class was being over run by manual transmission vehicles with centrifrugal clutches, clutch management and two wheel brakes enough to warrant a rule change.

Maybe the the change was made by people that DON'T
have the equipment you mentioned Michael??

What a pain in the neck!!!!!!
😠😠😠😠

SuperOwen ·

Rev6 clutches etc that are centrifugal assisted aren't lock up clutches (page 199). The rules regarding pneumatics etc would be more focused towards sneaky multi stage setups so a call to andra tech may hopefully get that clarified for VW applications. I'm guessing those rules are aimed at keeping door slammers out of super sedan.


4 wheel brakes are a PITA though!

modnrod ·

Actually centrifigal assist is exactly what a lock-up is, the bike guys have only been calling them that for about 30 years.
They obvioiusly meant "multi-staged adjustable" I spose.

Not trying to be clever, but jeez it just gets frustrating when every year ANDRA brings out new rules, but call the items different names to everyone else! They cause vastly more confusion than they fix.

I rekn if $100K ex-Doorslammers with Lenco's want to turn up thinking they have it in the bag and get trailered by a manually-shifted hotrod, bring it on!
Do your stuff Henry! 👍

My front wheels and struts are ready to go for brakes but it's the plumbing and master cylinder that will take some time.

dangerous ·

Nothing in the rules to say that they have to both be connected to the master cylinder.
My rears are on the foot, and my fronts are on the staging brake.
Work very well and easy to plumb.

andrewmurphy ·

An update on the four wheel brakes.
I have spoken to the new ANDRA technical guy who has emailed the national rules committee to get this reversed. No one knows why the rule was changed so a page edit will be sent out by the end of the week.

He has also said my ballistic blanket is good to use and will email me that confirmation too.

He seems like a reasonable guy to deal with. Here's hoping sanity continues to prevail.

Stanley ·

Nice work Andrew....makes you wonder though how many other rules have been changed on a whim. Just as a point of interest i'd like to know the trigger for a rule change, other than safety of course....is it just an idea a single person has or is the result of a majority decision?

andrewmurphy ·

From what I understand.....and don't quote me ......

Anyone can submit a change request. It will go to a national rule committee for that class who review the change and it will go into the next rule book. If it is requiring an earlier change than the next year they submit a page change. And notify people through their websites and through ANDRA notice boards.

There is good info on their site.

Did Mr Andra have anything to say about vw clutch management setups?

He didn't except to say that the changes look like a carry over from super gas which doesn't make sense because I looked at the 2013 super gas and it doesn't say anything about it.

I'll ask and let you know.

andrewmurphy ·

ANDRA are going to be sending a page update that will reset the suspension, clutch and brakes back to the 'general regulations' so there will be no issues with the rev 6 clutches.

Well done Andrew.

Is there still a push for a drag tech section? If so, who would be moderator?

thanks

Dave

I've created the Drag Tech section, and you're the moderator 🙂

Have fun folks - it's a sub-forum of this forum, so it should be easier to find than if it is off by itself.

thanks
Andrew
