Our pal Steve Stafford has done aero development for factory teams in IndyCar, IMSA and NASCAR. Tonight he’ll join us on Grassroots Motorsports LIVE! presented by CRC Industries to discuss some basic and advanced aerodynamic principles and how they apply to all of our cars on track or on the autocross course.
Join us with questions and comments live on …
hey, I know that guy.
bring the questions...
I have a concert to attend, but I want to know more about underbody directed airflow vs added chassis tubes on a stock floor. I’m a drag racer and wonder if it’s worth the time and effort on say a 10sec/125 plus mph 1/4 mile car faster or slower. Can’t do any visible exterior mods for airflow.
I hope to put a real drag pass on the Challenge car tonight or I would be there!
And hello from the studio. The Corvette's on the lift, and Steve is doing aero stuff.
This is one I'll be watching when I catch up to it. Considering as flat a floor as I can fabricate for the Supra. Will likely involve oval exhaust tubing to make this a reality. Just... so... much... work.
Then again, most of my theories have panned out on this car so far, and I keep coming back to this one, so... I'll get to it eventually. Lots of research first.
Yeah, I need to go back and re-watch it as well. Lots of amazing info shared.
In reply to Ranger50 :
you can get the added underbody tubes to act as fences to direct the air under the car.
depending on where you put them and what sizw/shape they are, they COULD make downforce, but will likely add some small amount of drag. the net result will probably be a slower trap speed, but the downforce/stability effects may result in better total times (if the changes help get traction early/mid track).
as a side note on my previous post, the chassis tubes may have secondary ( actually primary) goals of chassis tuning which could significantly help the launch and first 1/4 of a drag pass.
Make every part so at least two jobs, for efficiency...
