I had such a blast that I cannot even describe it!  Oh oh wait it was like a day at Kings Dominion with out the long lines!  Great job to all who designed the course and chalked the cones!

I think I can speak for everyone when I say "Awesome course!"

I didn't hear one negative word about it all day. Good speed, not too confusing, good course to just focus on driving. Great job Justin.

Absolutely great course even though my car acted up on the 4th and 5th runs. (time to do some overdue maintenance on the carb, etc.

FYI According to my MaxQData I saw 1.77 G's on the loop on my 3rd run. I think it was the second "pass" near the grid side of the loop. Yes, fresh Hoosier 25B slicks work well on a hot day.

Question: Do any of you use MaxQData? If so, do you ever have runs that show about 10 seconds shorter than actual at VMSC? Many of mine do but I've only run it at VMP.

No video this time. Mounting my camera on a tall mount to bodywork apparently caused too much camera movement (think "crack the whip").

Thanks again for a great event and course!

1.7 without significant aero is highly suspect, especially if you're also showing erroneous times in other places.  Were you in a full-on drift?  Because that can cause strange readings on accelerometers.

I ran a Gtech Pro RR for a couple of years and just upgraded to an AiM MyChron3 system this year.  The MyChron sporadically shows wildly inaccurate readings, but I can expect about 1.3G max laterally--I can't even pull 1.7 on 20-degree banking.

I'd think if street cars are pulling 1.2-1.3G a formula ford with well setup shocks and brand new R25B Hoosiers should be capable of 1.7.

It is a good point about accelerometers giving false readings when a car is sliding or has a lot of body roll, but I was watching Dick run and I'd say the car was locked down with little to no sliding going on and zero body roll.

Bernard is correct. Keep in mind that for a road race FF 1600 (no aero) where they almost always have hot race tires and very few bumps 2 g is common using sophisticated data acquisition. Way back in 1985 Road and Track recorded 1.28 g with a Swift DB-1 FF1600. Tires have come a looong way since 1985. My tires were brand new Hoosier 25B racing slicks.

FYI the car with driver weighs a little over 1100 lbs and the floor, including driver's rear end, is less than 2 inches above the pavement. HP is about 114. I easily hit the rev limiter for a couple of seconds before the 180 at the far end (about 68 mph).

I didn't realize you were in one of the Formula cars.  Sorry for the confusion!

No problem. I guessed that you didn't realize what car it was (yellow formula ford). Smiley

FYI I think I found the cause of the power loss on the 4th and 5th runs. Piece of silicone rubber in what is called an air correction jet above the secondary emulsion tube in the mandated FF1600 two barrel weber carb. It apparently kept the secondary carb barrel from either opening or having fuel.

Also did some other stuff to basically "try everything" since it is rather hard to test a formula car on the street. Sad
