Creating A Dedicated Track Gtr

[Sydneykid]

I'm very interested in your opinion gtr660hp, you are suggesting to start with a very expensive car there.

The key difference I can think of between the gt3 and a gtr is the gt3 is about 300kg lighter.

But if you start to spend big $$ on your components surely you should be treating it as a business. And if its a business then you should have a business case.

How many sec/lap does a motec give you over any other ecu at 10% of the price?

How many sec/lap is $15k of suspension worth compared to $5k of suspension?

And did you break the diff and driveshafts before you spent $5k on custom ones?

Gary might have an opinion on those questions too....

I totally agree about the gearbox though it sucks in competition and you have to spend big to get a good one

I don't think you can suggest that having a v8 supercar driver drive 2 roads cars once is a god way to compare them, better to look at lap times at the same track for well prepared cars.

My race car owes me under $30k and that includes the 1 1/2 engine rebuilds so far (yes I suck at building motors). Its about 1 sec off the class records at the moment, and hopefully we can get closer with more track time.

I can answer the suspension question (so what's new).

Lat year the GTR was upgraded to Proflex from a Jap brand, cost around $8K, net. It was the length of the straight at Eastern Creek faster over 15 laps. That's a lot right? Well not really because it was only 2/10ths faster on lap 3 (the usual fastest lap). But it was almost a second faster on lap 15 (the usual slowest lap). Because with the Proflex, it didn't work the tyres as much and they last longer before overheating.

So if you are looking at single lap times, they were bad value for money ($8K for 2/10ths).

But if you are looking at the race time (to do 15 laps), they are worth every cent ($8K for 10 seconds).

Because, it finished second with 3rd 2 seconds behind, 4th 3 seconds behind that and 5th 1 second behind that.

With Proflex finished 2nd.........Without Proflex would have finished 6th.

That's good value for money in racing terms.

what 1990 GT3? they weren't in production to the late 1990's.

GT3 or RS or CS, all the same thing. Different years, but they were all the same Porsche factory track banger

LOL...there is my opening. My little GTST would hand most R32 GTRs their ass if only i had the same power.

...And the Nazis almost won WWII, and if i wasnt poor, ugly and uncharismatic i would have boned Keira Knightley by now

What about getting that power to the ground?

[Roy]

Thats the challenge isnt it...thats why i was originally a bit disapointed that my car handled the hike in power. I was hoping it would be a but more of a challenge to get the power down, but who knows what more power would to the character of the car

After a couple of days of putting a stripped R32 GTR back together, i awas shocked by the amount of crap in them. First step is strip the things...from there, leave them std and they will be quick

[gtr660hp]

Yeah I stripped mine to and it was eventually quick

Have done some laps now in a 2004 model Porsche cup car- wont be bothering with a GTR anymore (and the 2006 are way better again)

Hey gtr660hp what times do you run on the national circuit at QR with your current GTR? Id imagine pretty quick times, since it sounds like you have heaps of experience with building them up. Maybe the other tracks to if you run them, sprint, clubman, and sportsman?

Why dont we ask Jimmy Richards about the diifference between the porka and the R32 he drove to win the 1992 bathurst.

Does everyone remember the infamous you're all a pack of A##eholes. He must have some fond memories of the day:-)

Buuuullllllllshit! Buuuullllllllshit! Buuuullllllllshit! Buuuullllllllshit! Buuuullllllllshit! Buuuullllllllshit! Buuuullllllllshit! Buuuullllllllshit! Buuuullllllllshit! Buuuullllllllshit! Buuuullllllllshit! Buuuullllllllshit! Buuuullllllllshit! Buuuullllllllshit! Buuuullllllllshit! Buuuullllllllshit!

I enjoyed the fact that they won, cant see why everyone else was upset?
