Serpent Project 4-X
#676
As long as the FDR checker reads at or above the minimum you are ok. In any case, I have tested many different gearings and did not go faster. Ultimately I would advise to just run thr hearings I originally posted for the 2.0 cars.
I think we are barking up the wrong tree here and I am sorry for the trouble caused. Again, I confirm that the difference is infinitesimal.
The only way to get faster is to focus on chassis setup and driving.
Let's please re-focus the conversation on that.

So my setup would be this according to Can-Am rules:
NB: Serpent Project 4X was checked and due to the O.D. of the center pulley the internal is not exactly 2.000. Testing revealed it is closer to 2.005. For Serpent Cars ONLY, the drivers who wish to be as close as possible to the Minimum FDR can use the following spur/pinion combinations: SS TC => 99/32; Stock TC => 97/36; USGT => 101/46.
According to the special rules for the Serpent I can run a 5.389 FDR in Stock TC and all the other racers have to run 5.400 - the minimum FDR. If everybody is okay with this then we can move on.

At first it was fun but not anymore.

I'd like to also add that the 4X is an amazing car.
I realize that there is a lot of noise being made around the awesomatix. What people don't realize is that the USA team is led by a very smart man who has gathered not only some of the most talented on-road drivers in the US but those drivers also happen to have an amazing communication dynamic and proven testing techniques. Don't get me wrong, the awesomatix is an amazing car; but the success of it in the USA is mostly due to the team it is made of.
A lot of us have focused on power. And we have been led to this mentality by efficient marketing, like sheep. While the top drivers have spent all their time focusing in their skills, the rest of the USA has been focused on who has the more power.
We have to focus on what matters; that is driving, setup and the ability to adapt to various conditions/layouts.

Not trolling or joking. The Serpent came at higher FDR with the checker compared to the calculated FDR. All other brand cars tested very close on the checker VS calculated FDR. That being said, this does not translate on lap time. I tested roughly 40 different combinations, including Xray drivetrain in my Spec car. Same lap times.

Oleg, if this was your car wouldn't you want to find out what was causing such a strange issue? Wouldn't you be concerned? I doubt you would just accept it and move on. According to many people on here the problem can't exist - but it does and with no agreed upon explanation from the community 

Joe mentioned it didnt make a faster lap so make the fixed FDR with a +/- variance , even if it gave me that much advantage is not like im going to get rid of my current car and buy a serpent

Ok. Back to setup.
I have been working on freeing up the car on our high grip carpet, especially mid-corner. The car turns on a dime on tight turns but it feels kinda stuck when on-power in faster speed corners. The grip at 360 is just insane.
Raising the roll centers helped; I now use the mid-high position on inserts. 0.5mm roll center shim Front, 0 shims rear.
For this Sunday I will play around with wheel base. Mostly moving the rear arms forward. I will let you guys know who it went.

I'm upgrading my durability rating of this car to very good - way may durable than it looks. Zero broken parts after some horrible incidents. Maybe I've been lucky but this car is definitely not fragile - an FYI for those assuming it is.
Anyway, as far as tuning goes, I have the car working well. Balance is good but overall grip is a little less than my other cars - looks really stable but feels kind of "floaty". Perhaps due to less chassis roll/lean in the corners. I run a lot of droop (like all my cars) but the effect seems different on the Serpent. I need a little more overall grip but don't want to ruin the very stable driving characteristics. My first instinct is softer roll springs front and rear but I assume stability will be lessened?

Yes, I have been running mid-high in both spec and Mod. The traction is super high at 360V2. I feel like it freed up the car Mid-Corner. I felt less resistance, less stuck if that makes sense. The car also felt a little more agile, kind of a "lighter" feel.
