Look who ran with us at the Glen on Monday and Tuesday!!

[06mach1]

As seen below, a few of us BMO members got to run with the Phoenix racing team at the Phoenix CMR event this past Monday and Tuesday. It was a blast!!! Granted, they showed us how slow we actually are! Those guys were flying! Once I go thru my videos, I hope to find a few clips of them passing me like I am standing still and I will get them posted. They were there testing for the Tudor race coming up this weekend.

That's cool. Did you guys go over and talk to them and which drivers were there?

 

[dmichaels]

Very cool - would love to drive with one to humble me

I'm interested in what suspension setup they run and why. Some people install hydraulics to get their front wheel that far off the ground!

 

[VoodooBoss]

AFAIR they use Penske dampers and no Watts link. Hopefully Rob will stop in and confirm that.

Here is my take on the setup, you remove most or all rear roll resistance (small or no bar) the gets more weight and load transfer to the outside rear tire and takes most or all of it from the inside front. THe rear weight transfer helps the, on our platform, already overloaded (understeer) outside front tire. That helps balance the car and utilize the excess rear grip while cornering. The other benefit is as you are unwinding and adding power the rear has a decent loading on it and gives good traction on exit.

The down sides are less sharpness at turn in as there is a lot of "wallowing" as the weight is moving towards the soft rear.

Just my primitive grasp of cornering dynamics.

Lets see what the pros have to say.

I spent some time with them but can't remember their names. Their mechanic and driver of the T2 #77 helped me out by fixing a caliper problem. Really nice guys. The T2 car runs Penske's with the standard FRPP part...panhard, LCA's. Nothing special. The Conti cars, there were two there run the 302R setup with AST 5200's. They told me the Conti cars were running 2:02's and the T2 car was running 2:04's.

Really good group of guys. It was a lot of fun pointing them by then trying to keep up for a turn or two! Key word there is trying!

What you're saying makes sense--you can see the "wallowing" in both pictures. I'm used to thinking that race cars have super stiff spring rates and never squat or lean, but that's clearly not the case.

...and apparently they're still going fast. Cool beans.

At the 50th at LVMS there was a 302R in our run group. My son saw him on track and laughed when I said I wanted to see how close I could stay to him. I soon found out way as he blew past me and I couldn't hang with with him for one corner.

Sounds spot on to me. Trying out the no sway bar and watts link at lowest roll center Sunday.

I went thru all the videos I took and was able to find a few that had Phoenix Racing "fly-bys". For some reason (I think go-pro battery died) I missed the best shot of the day when I was behind them in turn 9. Both cars had the left front wheels in the air as in the picture above. Was really cool! Here is one of the short clips. Have a few more to load yet.

Here is one of me following the T2 car for half a lap.
Not the best lap because of traffic but still cool.

Looked good Mike...did you get the tire pressures squared away
