ON A BETTER NOTE MY CAR IS RUNNING VERY WELL WITH THE CARB I BUILT. I AM ANXIOUS FOR OUR SPRING BYRON EVENT. WITH A SET OF MT STREETS I AM HOPING FOR WAY DEEP 11s AND MAYBE EVEN THOSE 10s YOU SOMETIMES MENTION BUT MAY NEED A BETTER DRIVER. MAYBE CHRIS WILL STILL BE WITHOUT A CAR.

(I HAD #1 OUT TO CHECK DAMPER POSTION AND THEY WERE TOTALY BLACK FROM FUEL)
Were the plugs checked after the dyno? (DON'T KNOW) Compression? (I BELIEVE 9.5:1 AND HEADS ARE AFR 225) Does the car have boost and fuel pressure guages? (YES) Did the dyno setup have boost and fuel pressure monitering? (WAS NOT THERE)
What fuel was the engine dynoed with? (I WOULD GUESS 93)
What fuel is in the car? (93 PUMP GAS)
With a new install there is a strong possiblity that crap from the fuel cans, tank, fuel lines entering the injectors (I UNDERSTAND BUT DOUBT THIS WAS THE CONDITION HERE)
What are you using for a controller? (SEVERAL PEOPLE HAVE ASKED BUT I SHOULD NOT SAY YET)

The HP numbers you are quoting are possible without a supercharger--was the blower added after the dyno run? (DYNO WAS PERFORMED WITH 9LBS OF BOOST)

How much timing advance was being run? (12 INITITAL AND 38 TOTAL ON PAPER. I ONLY CHECKED THE INITIAL AND IT WAS 12)

Ten easy break-in miles---sometimes the leanest conditions with advanced timing occur with easy driving

If the engine was in such a tune to cause that much damage, it would of run very poorly on those 10 miles (IT WAS ONLY A LITTLE ROUGH THEN WENT TO HARDLY RUNNING AT ALL)

SUPPOSEDLY THEY WILL BE TEARING DOWN THE MOTOR THIS WEEK AND WE ARE ASKING FOR PICTURES.
