Red Devil mkII - The Journey Continues

I like the increase the boost part, your not running a LSD yet are you Sean ?

Also are you running real semi slicks or just 595 rsr's

Car looks fast from the video

No LSD at the moment, car felt to have sufficient grip so that'll wait at least intil I feel my driving and lack of LSD is the limiting factor. Though a plate style diff is around $4k installed so it may never happen...

Yup, running semi slicks which I got off Sharkie (if I recall correctly) sometime back, they are old but still gripping well. I'm running Bridgestone RE55s on the front and Toyo R888's on the rear on Audi TT rims, the tyres were made in 2008. So yeah, old, a bit hard, but still gripping better than street tyres. Will run new tyres for next years timeattack, not yet sure what tyre to run, and will run on the enkei's.

United Fasteners in Adelaide stock them. I bought 6 for $4.00. If you're looking for trade quantities Blackwoods sell them per/200.

Thanks Stuwey. And you ran from on your turbo bolts?

[Stuwey]

Made a half-arsed attempt last weekend but kept getting distracted by Bathurst.

I'll have a proper go once i've got all my tools at home, not that I think it's currently leaking anyway.

I've booked my car in with NA Autosport to look into the turbo bolt issue. They run in timeattack, just completed world timeattack and have built many race cars of various forms of motorsport. The owner, Nick, first comment regarding the bolts was are they genuine VW bolts... which they aren't. Gav, Jimmy or Ant, do you know if the standard sized bolts fit the larger manifold? Question for anyone, anyone have experience or reason for not going back to genuine bolts? Seemed a little obvious when he asked, so am curious.

Anyone know the torque setting the bolts should be, or bolt details?

[Stuwey]

Best info i've found on the net is 35Nm.



Using genuine bolts, i've had no issues.

*the ones supplied by ECS for my K04 upgrade didn't look as nice as my originals, so i reused them.

VW ones aren't long enough for the after market manifold.

Ahhh, ya killing me Gav. Lol

Thanks for diagram and input Stuwey.

Well wouldn't THAT be about right. Haha.

I have a spare set of nordlocks at home that will help you. They are I.D 8.7mm for 8mm bolts. PM me with your details and i'll post them to you. You need a set of 3 yeah? I'll ask the fitters at work about torqueing them - you have to go a bit over so that when they get over the hump and click into place they settle at the correct value. There's a chart for it but I'm not sure how that works if you use one use stretch bolts like the VW ones.

Don't know if you've looked into it already or not but I just had my K03 exhaust manifold off and the mech. said that the mounting surfaces on both sides of the exhaust manifold and also the turbo were so far from flat it wasn't funny. He went through two belts before evrything was square and reckons that'd be a big reason why they'd not heat uniformally at the flanges and also blow gaskets.

... Bridgestone RE55s on the front and Toyo R888's on the rear on Audi TT rims, the tyres were made in 2008. So yeah, old, a bit hard..

Probably near their life's end, id say. Tyres are too old and the compound and case structure of an '08 tyre is no where near the current tyres. Yoky A050R are about the best there is today. Great grip, right down to the canvas and good life. We find that the A050R's only loose about .6 sec from new to ****ed!

Just gotta pressure them right, setup the car to suit the very stiff side walls and when not in use keep them in a dark place....

Thanks sam, will PM you. Very interesting comments on the surface quality. It is something I had considered, but overwhelmed with how to rectify. And you're running the factory manifold? I wonder the quality and surface condition of mine... Knowing the time, research and dedication from Anthony and those who've worked on the car, i'm inclined to think this is just a little gremlin that arises, perhaps more pronounced due to track time. It's running very similar gear to Gavin and his has seen plenty of happy lap pace and commuting, and still ok.


39er, thanks for the input. Will start my tyre research shortly. Doesn't like like I'll be hitting wakefield this year. VWNats in March is a sure thing.

The A050R is supposed be an upgrade of the A048R which handles heat cycles better but despite comments I've read of the A048R's going off quickly, mine have held up well over the past 2.5 years of use (about 10 events). In fact, in the last 3 track events, I've set 2 PB's and almost set another PB in the 3rd (which I was trying NOT to do since this was a regularity event).

I'd be more concerned about the possibility of the older tyres delaminating as the rubber hardens and loses its bond to the casing - I had 2 old stock A048Rs fail on me before I bought my current set of fresh stock tyres.

[sambb]

Yeah mine is just the stock factory manifold for the K03s.

Sorry to shoot you down but your dreaming if you think the A048R's were ever any good. I ran them for 3 years in IPRA and hated them. They were only ever any good when green and they would loose around 2 to 3 secs a lap from green to their 2nd or 3rd run. Sure, they never wore out but they hated multi heat cycles. To be competetive we had to put 2 new tyres on the load side every meeting, where as the well heeled replaced a set every meeting, sometimes even 2 sets over the weekend.

The A050R's are simply astonishing in their grip and life and multiple multiple heat cycles dont bother them. Which is why 2nd hand A05R's are very hard to come by as the well heeled racer doesn't need to change them every meeting....

Try them, you'll never go back. Plus get an instant second or two faster lap timer BEFORE you start to play with your setup. Plus, in Regularity trials you drive to a time, not drive to set a time....

Thoughts on turbo bolts.

ARP, best fastner brand I can think of?
Caterpillar, 99% of the off road racers built their cars out of these as they are tough-as?
Do what the IP boys do and plain weld the turbo on!
