Bo Butner's AA/SM

Curious to what's going on with this car. No "traditional" scoop, and a few large bulges on the hood. Is the air intake set up as bottom feeder?

Yipes, I need to read the rule book closer. When did blowers become legal in comp other than the AT classes?

Whilst I plead ignorance, how big is the engine?

399 cu.in. @ approx. 2,000 hp. By upping the boost, it could run in the high 6's.

Yep it is definately an index buster They have it dialed back now and can take the hits but it will run out of boost sooner or later.

8.0 lbs/ci for SS/AM = 3,200lbs

Where is he packing all the ballast in that little Cavy?

doh, it shows how out of touch I am in comp.

I read this today on nhra's site regarding AM in this year's updates to the rule book.

Comp/Super Modified

Page 128 (12/05)

Classes: Replace class designation with, "AA/SM – 8.00 pounds per cubic inch."

That would be a brutal weight (3,200 lb.) to run the car at.

6.00 makes more sense, and a much safer weight.

Bring on the Pro 5.0 cars, 10.5" tire cars, and sport compact cars that fit!

Nothing wrong with index killers if they can get them to hook...every pass....

It becomes self policing after a few runs.

It is an 8.00 pound class, like you said. The rule revisions say so, and those are revisions to the 2006 rule book which states the class is 6 pounds. After the book was printed and a lot of initial arguing, NHRA changed it to 8 pounds. The class has a 2700# minimum weight anyway.

 

[Mr. Jean]

Thanks Jamie. I was quoting the book. I missed the revision.
