I think you will find that the Ian Ross GT350 is limited to only 0.0000007500 squillion RPM (but I digress)...have you spoken to CAMS/other promoters about eligibility profi???

The car isnt a real shelby but came from the shelby batch, so its the closest possible fake. car before it was a shelby and the car after was also.

The only historic category ive talked to is the new american muscle car series
starting in march. i have also been looking at the Improved production road and that looks hopeful

7500rpm is still plenty but our engine is safe 8000 and has seen nearly 9000 by accident but they sound beautiful at revs

Gavin Bullas'es 69 mustang used to see 9000rpm every lap back when it was in groub NC

Dunno what your budget is profi (don't want to know) just trying to suggest opportunities where your Stang might be eligible....dunno if you have ever been around Mount Panorama but that is certainly something to aim for (thats why I suggested you contact FoSC)....nine grand is fine, if you have a friendly engine builder who works and supplies parts for free

9000rpm can be made safe look at NASCAR and our engine is along those lines.

I have never driven around bathurst, but its something ive always wanted to do. At the moment the car is a new setup and is a little bit untrustworthy in the handling department. Once its sorted and i get some more seat time bathurst will be on the cards.
Also need the practice there if sports sedans decide to go to the mountain.

BTW I build my own engines and import all the components its lots cheaper.

profi · 2 Feb 2009, 11:25

Safe for how long?? I think you have missed my point about preserving the machinery

Nice to hear of a driver who gets his hands dirty

if you build an engine to rev at these levels all the harmonics are best at the revs so if its built to rev a 9k and only rev it to 7k the harmonics are all wrong and it wont last as long. Thats why NASCAR have very few engine failures. But valve springs should be changed on a regular basis.

So not reving it as much will wear it out faster

That may be the series when i receive the package in the mail ill get back to you with more info.

But i wouldn't it be great if the tranz am's came out

Understand what you are say about nasty harmonics etc...however, you do have to look at your torque curve and power curve and say "well not much point in revving beyond where the torque starts to drop off!"

Look forward to hearing about this "new" series...meanwhile don't ignore other opportunities

Were only reving our engine to where it still makes power between about 4k an 8k

Im open to anything just want to get the car out in a competitive environment.

Ive known about FoSC for a while now and bathurst is one of the things that is near the top of my list.

Grant Wilson on the Gold Coast is trying to start up something of a Trans-Am series for similar cars to yourself to run at meetings like the Muscle Car Masters... might be worthwhile tracking him down.
