CEFX Evo 2011 is finally here!
Well, it's much later than I wanted but looks like everything will be in stock while I am at IIC. All the kits/parts are up on www.cefxspeedshop.com
so they are ready for pre-order. I am going to work on cutting graphite all today and I should have a fair amount done before I head off to IIC. The new mount/motor plates will be here next week and otherwise we are just waiting on the shoulder screws for the steering rack which will also be in next week.
The Evo 2011 is based off the car I ran at the Snowbirds last year but with a lot more testing and development done with the flexability of the car. The main focus was to find not only traction but an extremely high level of drivability in order to push the car as hard as you can each and every lap. The one thing I hated before was how my car would change balance over a run and was really sensitive to the grip of the tires (use, additive, etc). This new car, I've run as much as long as 14 minutes on a pack and managed to run equally fast lap times at the 1 minute mark vs the 12 minute mark with out a change in the traction/steering that the car would produce.
The chassis is a lot different now being 2mm and only 88mm wide. The cut outs and bulkhead supports/spacers allow us to "release" the bulkheads in a manner that give the car more flex at the direct front and rear of the car. This allows us to leave the center of the chassis solid for easy mounting of electronics but more importantly making those electronics a non-factor in the flex of the car - With other cars, it is critical if you use battery tape or servo tape to put your battery in. It's critical of all the little details because you can be hindering the chassis flex through the center of the car. With this method, we focus the flex more at the ends of the car allowing the chassis to work better with the top deck for a longer/more linear "spring rate" of the chassis and top deck plus the added bonus of de-sensitizing the chassis from anything you may do with your electronics.
Also with spacers under the bulkheads, they allow me to move the droop screws "inline" if you would with the shocks so you aren't twisting the suspension arms at droop. This also reduces the chance of the chassis bottoming during cornering. It works in combination with the new 2mm chassis to raise the differentials 1.5mm from last year's Evo for improved effeciency, traction and responce.
The super long top deck pretty much eliminates any chance of tweaking the car. I've run my test car a lot the past few weeks and have not been afraid to put it to the test with aggressive driving and some big crashes. To date, I've damaged other parts on the car but still have not tweaked the car or bent even the old motor/mount plates.
Now, some may hate the slider rack style steering but after running a lot of checks on all the different steering systems, I am convinsed this is one of the best and most simple set-ups. The responce is fast, the ackerman is extremely good and the bump steer is fantastic. Yes, it does get some play after a few hours worth of packs on the car (yes, I said hours) but I have yet to have the car not run straight and I really, really like the steering and feel from the car.
The shock towers have minor revisions but the main change is in material/shape and weight being lower and lighter.
I think the people who have seen me running and testing the car at The Gate and MSI would easily agree that this is the best TC I have had on carpet in years!! I've had so many positive comments from those who have seen it on the track. Honestly, just with my own feel and expectations I am really looking forward to IIC to see how this new car stacks up against the best TC racers on the planet.
Time to get to work here cutting and building - Tomorrow it's off to MSI for final shake downs before the flight to Vegas on Monday!!
If anyone has any questions, I'll do my best to keep up with them even during IIC.
