I was looking at natsoft for timing results of the evo/wrx meet over the weekend at EC. Over half the field managed sub 1;50 times, with many in the low 1:40's. Has anyone managed these sorts of times?
I found a engineer who built the Bathurst 12hr MR2 in the 90's. He did mention that over the top of the Mountain the car had a 'spooky feeling' on the high speed cornering. I have been pondering on why this happens and how to fix it.
Any thoughts on this aspect of the MR2?

evo/wrx day all the cars under 1.50 all have min 240kw atw's. Cam Dyle's evo that did a 1.40 has 460kw at all 4 wheels. I know that there is a 1.47 in my mr2 with more practice and i have 160kw atw. when we put some balls into it i think a 1.42 - 1.45 is quite achievable and will be reliable

the key will be to get as much weight out as possible and get the tyres working properly. My tyre temps indicate that the suspension setup is not correct and I am running too much camber for such soft springs and shocks. Therefore my total grip is down which would indicate there may be half a second or so just in mechanical grip to be found. As for the "spooky feeling" - I think you'll need to completly rose joint all the suspension to help this. Phoenix Power did a full set of these but I do not know if they are available any more.

460kw is an amazing amount of power for a circuit car but like wet toilet paper, it wont last long! Its close to 600hp at the wheels and who knows at the flywheel. Clearly set up has more to do with making a car very quick.
Here is the link to lap records at EC. http://www.eastern-creek-raceway.com/lap_records.htm
As you can see on this page, no one has a 600hp atw 4wd. The R32 has less power and plenty of restrictions and managed a 42. The startlet did a 45 but is a absolutely crazy car. It had a 2ltr Vtec squezed in the front of it. It was comparable to a SW20 with a 600hp Toyota 4.0ltr V8 in it! Now theres a thought...

240 atw is still plenty power plus they are a later model car with 4wd so I guess you have to expect this. Nissan S14 is a better comparison to an MR2 as they are from the same era, 2.0Turbo, well balanced car .

I agree with weight reduction. Remove as much negative weight as possible then replace with positive weight. Cage, bracing, cooling systems etc. I will remove everything possible in the front of the car to lose 50kg then put 6-7kg of bracing of the chassis and suspension points. Same for the rear.
I removed every bolt not used which will make up for all the seam welding through out the car. I sure I have removed more than I added as a matter of fact. Just a thought.

I found Lexan for $180 a sheet(2.4 x 1.2 x 3mm) if anyone is interested. 2mm is also available. Im picking it up next week.

Thought i would post Cam's lap at eastern creek he has set the car up for time attack only hence why so much power

I just watched Cams laps. Great piece of footage.
The engine sounds absolutely brilliant. What is the spec on the car?

It is certainly a goal to work towards

Cam's car is all carbon and lexan would weigh 1200kg runs a dog box and 2.3 stroker and has 439.5kwatw's. it is the goods but plenty of money has been thrown at the beast to get it where it is and a lot of heart ache but it all came together for him last week. Thumb's up in my book as his not a pro driver but a Accountant

sw20 non turbo,

No mods at all.. except for a removed spare wheel.

W rated tyres.... (pretty crap brand though)

1.17.1 wakefield park.

nice, how were you timing that?

girlfriend on the stands lol.

So yeah. give or take a second. i was doing 1 17s pretty consistantly though. (except my cool off laps)
