Just seeing who's coming down.

 

I'm down here working flags. Only 1 350Z; he's running in TTB. where all the spec guys go the last two events?

 

yesterday sure wasn't the best for qualifying or racing



This and the car had a lot of teething issues. More coming soon, including video.

 

Not my best qualifying effort.

 

Here's how bad the race is. That's me right behind Matt at the start.

 

John D had a great race in his new Thunder Roadster and nice video from this past weekend. We make a cameo at 3:10 as I made my way through the Thunder Roadsters after starting DFL because on no qualifying time (and being late to the grid).

Yea, it got pretty bad. I know alot of the cars stopped around turn 6 and a few drivers almost realized it at the last moment.

 

So after the first race after the upgrades and other changes it seems that there was too much weight taken off the front end of the car. This is a bit of a disappointment since the car was handling so well before hand, but I should have seen it coming considering how much lighter the new top end is. There is now significant under steer and the key indicator of the left front wheel locking up easily. Alignment was right so I think I can rule that out:

Left Total/Center Right
Front
Camber -2.9 -3
Caster 8.5 8.5
Toe - 1/16 - 1/8 - 1/16

Rear
Camber -0.1 -0.2
Caster
Toe 0 - 3/32 0.13


The car was balanced and cross weighted prior to the race and on paper looked to be decent, not great but almost perfect 50% cross weight.

Cross weight 50% 50%
weight Dist front 45% 44% 44%
weight Dist rear 55% 56% 56%

One thing I did not do though was account for fuel. The car has ~3 gallons in it when weighted. Once I added another 10+ gallons I know it threw it off, but even as the fuel went down there were issues.

Bottom line is I think moving the battery forward is the next step. Right now it sits in the rear. The easy answer is to move it to the passenger foot well, but I would like to keep the passenger compartment as is. Any ideas?

 

Softer front springs maybe? or add some ballast?

What is your total weight? with or without driver?

 

Was reminded I can not move the battery


So now I need a different approach. Not sure if a spring change will solve all the issues I am seeing. I need to get access to a set of scales and remeasure with the correct fuel levels.

 

Left Total/Center Right
Front
Camber -2.9 -3
Caster 8.5 8.5
Toe - 1/16 - 1/8 - 1/16
Weight 551 1085 534

Rear
Camber -0.1 -0.2
Caster
Toe 0 - 3/32 0.13
Weight 683 1359 676

Totals
Weight 2444
Crossweight 50% 50%
weight Diss front 45% 44% 44%
weight diss rear 55% 56% 56%


This was with only ~2 gallons of gas but with 180 lbs of driver ballast.

 

Huge rear tires.....

 

For understeer??!! No wonder you are getting out of racing.
