Excellent sir, I will work on my plan to make the car behave more neutrally. Currently I can adjust slow speed rebound dampening and camber very generously. Give me a couple of weeks and I will present my test methodology so you (and other TMO members) can provide suggestions as to how to go about making my car more neutral. I would also like to add that after reviewing my track vidoes, I do indeed have corner entry understeer in off camber corners. I plan to purchase an AIM solo 2 DL to gather as much data as I can (and interpret) to advance in a more educated and scientific way.A vented hood will be better than stock at high speeds for those issues, not sure how much you can quantify that but the principles are sound.
You are correct that increasing the rear ride height will help to shift vehicle balance toward neutral or oversteer compared to your current setup (as you are "extending" the lever that the weight of the car has on the rear suspension), but again, this will likely have the biggest effect in the corner entry phase as opposed to mid-corner.
You should put a test plan together of things to try and aim to change settings and figure out how the car works with each of those settings during your next track day. Stick to your plan and resist the urge to knee-jerk adjust "the other way"; you can do that after you have gathered your data. If you find things that don't work, you are still learning something useful.
Of course! I have had a few spin outs and off road excursions and have learned to not make the same mistake twice...well..this past weekend I did spin out twice in the same spot but I shall leave that behindLearning is a life long adventure.....savor all its offerings!!.......the dumb one misses his opportunities to move foward..................................
Yes sir, trail braking was a helpful friend in short ~3-5 second corners, but in that sweeper which is about 15 seconds long it did get annoying TBH. Every time I go to the track I fall in love with trail braking all over again. ROTATION!If you're not already doing maybe trail braking in the corners where understeer is present would help shift a bit of weight forward and help rotate the car.
So it is mid corner ON throttle. The apex of this particular turn ('The Carousel' going CCW in MSR Houston) is very late, about 75% of the way through the turn. I will post a video below to help me illustrate.Mid-corner ON throttle or OFF throttle? Makes a big difference...
Have you made the apex and are getting to the gas...but you need to add wheel because you are pushing wide when the weight transfers aft/lose front grip?
Or ...or are you about to make the apex but see that you need to add wheel because you are pushing wide w/o touching the gas...too much energy at front contact patch?
The understeer happens ~2-3 seconds before hitting the apex while on the gas so I must release the gas slightly to make the apex. On corner exit the car rotates nicely as I apply throttle.
It appears that your last statement represents more closely what is happening to me.
In the 2nd video (after the adjustments) you can hear me releasing the throttle (from ~85mph to ~80mph on the speedo) because the car is pushing and am going to miss the apex.
Excellent sir! At my home track I am keeping up with Porsche Caymans and Boxsters in the Blue Solo group (on a Green, Blue, Yellow, White scale). The car is super fun to drive at my limit! I have thought about making the jump to the BOSS 302 module. Do you know if it makes a significant difference (ABS-wise) with 200tw tires, say Falken RT660? With regards to Advancetrac, I plan to do the #5pin mod. If that proves to be undesirable, I shall hit up Ortiz when I need a tune update after I install long tube headers this Spring.Always great to see more people flogging the 3.7 ponies out on track!
As for the advancetrac problems with the 3.7, I can offer some insight as to what I've learned from my own build.
Option 1: Boss 302r ABS module will disable both permanently (as long as it is installed) and give you improved abs programming for track use. As far as I've read, the drawbacks are that this module will light the dash up like a Christmas tree along with a chime. I found this option undesirable as my car sees extensive street use in all 4 seasons in the Northeast
Option 2: A "track" tune which will disable advancetrac. A few members have had success getting their coyote cars setup with a track tune by AED, but upon inquiry Shaun would not remotely track tune a 3.7 car. The other two major tuning houses for the 3.7, MPT nor AMR, would not help either. Eventually I found Ortiz Performance out of Texas and they were able to provide exactly what I was looking for: a specific track tune to disable advancetrac that I could flash using my SCT handheld at events and remove after the event to regain full advancetrac/traction control for the street.
Hope that helps when you are ready to take things to the next level and disable the electronic nannies
Looking forward to following you progress
And progress you will see! I have a feeling I will be upgraded to the Yellow run group on my next event. There will be much faster drivers there!
