I would guess at sea level and good tuning you would have a 11.30 car.

Should run there abouts at sea level... Was hoping to qualify for the trip to Topeka this year but it's not looking so good at this point... need to be in the top 6 for points and I've gone three races without winning a round so it doesn't look like I'll make it. Would be a great opportunity to see how she does with some air...

ive got a problem with low vac pressure, it does not effect the performance of the motor, but the vac on the brake booster. i am going to try an E VAC system, i hear they are around 80 bucks, but have not located one yet.

Hey Mooneye, you talking about one of these. I found this at Summit for $32



Fortunately I don't need one for the old manual drum brakes...
