I was/am mildly torn between BC's with Swift springs or off-the-shelf Koni Yellows and Swift springs. I have the Yellows, but keep debating it!

Those SBC RPF1s sure do look pretty!

 

Back from pocono!

LOVE the new stiffer springs, took me a good few laps to get used to it. No more roll and wait for the car to hookup in the corners. Super tight and controlled.

new best lap 1.48.2

You are where I plan to be in a years time!


Hopefully my project Z will go according to plan.


Happily subbed.

 

Summit point weekend in the books. 95+ deg out here now, crazy heat wave going on. Need to get more AIR into the cockpit. It was crazy hot.

The Z ran with out issue. Love this car.

New best time here. 1.28.6

Usual crew ready for action.

Great driving, Mark! Looking good!

 

Sweet dude, thats 12 seconds faster then me! Love to know your setup

 

I don't have any video of me around Summit (in fact I pretty much never take video.....I'm vain enough as is ), but I can give you a few speed data points, etc for reference if you want, Bluvision.

 

Yea love to see your data, more areas I can improve im sure.

 

Its all very detailed in this thread, check it out. The highlights. Stock motor. BC ER coliovers. Bushings all around. NT01 275. Stillen sway bars. No driver aids or ABS.

Nice! I only know this track from iRacing
What is your current wheel/suspension set up: rims, camber and hight?

 

Pretty solid lap overall. I actually ran pretty close to that in my foci, which is a surprisingly spry car when it is cool out (it would have been a DOG in 100 degree temps)....

Bullet Points from my 1:18.9 lap (TT3 car on Pirelli's/Aero):
Front Straight: 136mph (no draft) Brake at the 3
2-3: 110 Brake at the end of the first road
4: 112 min to 114 through the 'chute before the brakes
5-8: You average about 8mph less through the section. Should never get completely off throttle, even on the Nt01's. Best to run out all the way to drivers side curbing and almost "diamond" off the section so you are backsiding the following two elements. Allows you to get the best run and angle through 9.
9: Min speed on entry is 91-92mph at apex and max of 116-117 (limiter in 4th)
10: Min 90 on entry 103-104 as curbing ends and you avoid the hole in the dirt if you track out too far.

 

Z1 Anti fuel starvation Kit is installed. Similar idea to whats been posted with the aux fuel pump, but now using the new Holly hydramat. Z1 also provides a simple bent hard line that fits just so, inside the oem fuel bucket. Using the bent hard line and the hydramat, the extra fuel should keep the fuel bucket full.
PITA working inside the gas tank. Note you will need new orings on the top of the tank.

Hopefully I fixed my fuel gauge not working issue thats been going on. Replaced the fuel bucket with another from the junk yard, they gauge seems to function better now.

Holly Hydromat is some crazy voddoo magic kinda stuff. We run it in a autox/FSAE car and its rediculous how little of the mat needs to touch fuel to get full flow.

 

this will definitely be my next upgrade. looking forward to seeing this in action

 

That mat stuff is awesome!


By no abs did you actually remove the whole system or just take fuses?

 

Yea all the ABS is gone, look back a few pages to see. Made some ABS delete fittings and proportion valve.

 

That sounds interesting. Abs tries to kill me mid turn on track sometimes when I make a mistake that is easily correctable. Then abs comes in and tries to throw me into the dirt

 

Yea man, ABS does funky things. And After killing a ABS pump with no solution in sight, it had to go.
