Hi,
After reading the AI rules, it seems my 2012 boss 302 violates the LBS/HP ratio. @ 444hp/3600lbs (3850 with me in it),
it's well short of the 4218 (444 * 9.5) ratio needed to qualify for this class. Is that right? Even with the balast, I don't
think the boss can achieve the weight needed. Does this mean no bosses can run this class? Thanks for any tips.

Darren

Hi Darren,
Your Boss HP is the advertised rating at the flywheel and the weight you list is how heavy the car rolls off the showroom floor. (with the full interior and other do-dads).
The reality of the racecars is that we measure HP at the rear wheels, and that HP can also be detuned/restricted. In addition, the racecars are lightened as much as possible and it isn't uncommon to see the cars down to 3300-3600 lbs with driver.

Hope that helps and thanks for your interest in the series!

Some of us are under 3100, although not in S197 (new body style Mustang). We overbuild our motors and restrict them down to meet the AI rules. This gives us some room to "grow" if the rules change and helps the motors last under race conditions.
There are quite a few guys running the new 5.0 motors. I think with limited mods, the HP comes out right where you want it.

Then take it to the local Dynojet dyno and you will know what weight you need to get it to (with you in it of course). I think we are allowed up to 300lbs of ballast now.

300 lbs of ballast is the current rule for 2012 (up from 150 in 2011). Restricting the motor at the airbox is the easiest way. Rehagen sells a restrictor that fits in the OEM airbox that drops it down to approx 345HP/345TQ...

With ABS in that car, and 345HP, you would be at 3278lb minimum.

Todd,
Don't know how large your "driver" is, but I've had my AI FOX down to 2760 post race with me in it (170 at the time...).

Weight is just a number... What counts is how good ya look!

Was that with the PVC roll cage? LOL! I'm over 250 with my gear on, but I look GOOOOOD! And also important is how you feel.....

I used to ride motorcycles with a girl who wore a shirt that said "If you think you feel good, you should feel me". Best shirt ever!

Suprisingly enough that was with a NASA compliant 1 3/4" 0.120 wall cage. It was "pre aero", so the car has gained some weight in wings/splitters and is now 2910 with me in it... I've also put on 30 lbs in the last 7 years...

And that's why I can't afford to do aero just yet. I struggle to meet the HP:Weight ratio, and 150+ pounds would hurt pretty bad.
