The car looks great and looks really flat through the corner. Looks like the suspension is working correctly

would appreciate your thoughts on how you see the benefits of aftermarket engine mgmt... I'm looking to squeeze more out of the motor NA as well, and frankly not sure which direction to go with that

What spring rates are you track guys running, I know our 550 are not gonna cut it. It turns the splitter into a plow.

LiquidZ · 04-12-2010, 12:14 PM

Travis, your car has certainly come a long way! I really like it.

I know you are running Forgestar F-14's in 18", but what tires and sizes are you running?

Keep up the good work!

travisjb · 04-12-2010, 05:23 PM

not nearly flat enough, but thanks... need stiffer springs!

well about the fender vents. idk about reducing drag but it im guessing by allowing the air in the fender a place to escape it pulls out the hot air from the fender and allows more air flow to the brakes.

and as far as reducing turbulence again im just guessing but rather than having the air just push out of the wheel well with no place to go is worse then having a specific place where it all flows to. how far did MIT or MTI go with wind tunnel testing?

as far as aero goes look at ferrari aero. full underbody aero trays, vents and scoops in certain places to smooth airflow and reduce drag and increase down force.

if you really wanted to have much better aero, go to home depot and custom make a gurney flap out of door sealer (a line of rubber to keep the cold out) and get some aluminum sheets and make a full body undertray, cut out a few ducts on the rear of the bumper or use the nismo bumper with the vents. and your car will be much more stable at speed. the lower the car the less air that gets under it as well.

Update: looking at two options to upgrade suspension... 1) re-valving BC ER's to run at 18K/16K spring rates... and may have the rears converted to true coilovers in the process and 2) switching over to a new setup all together... leaning towards option 1 - have a call in to BC Racing to see what we can figure out

Car is with Junior - rear diff cooling is coming along well.. a few other little projects are underway

here's a fresh pic

Travis, what is the width of your wing? My APR is 67" and looks a little wide, but that is what they recommended, and I haven't actually seen it in person yet, only the photos the bodyshop emailed me.

For reference, the wing on my car is 68" wide so it will look virtually the same... HUGE..

Travis/Fathead - The diff cooler stuff looks sweet!

travisjb · 04-23-2010, 09:39 PM

Yours is definitely wider, but I don't have a measurement handy and my car is at Junior's... prob 6"

I'm very pleased with this wing from a looks and downforce perspective... at my last event, I was hitting 130mph at the end of the straight and transitioning to a long left hander under moderate braking, and the back end was 100% PLANTED! would highly recommend this wing

TravisJB: From your description, it seems that you are braking and initiating the turn simultaneously, then braking at least part way through the turn. This technique adds braking forces and geometry change to already complicated cornering forces. Have you tried that section of track by completing all of your braking while on the straight and running as deep as possible, then accelerating through the turn. This technique will isolate braking to the straight, and allow you to concentrate fully on traction while turning...the result being reduced time on this section and a position (or two)

Diff cooler update pics.

Travis, i am loving all the difficult plowing you are doing with your car. You are saving me tons of time and learning.
