been having gremlins with the race car this year - almost to the point that I lost interest.
short chronology:
engine not quite producing the power it should. topping out at about 5500 rpm, unstable idle.
fuel prob? - install higher volume fuel pump, larger fuel line.
problem worse
recurve fuel and timing
no diff
pull a few sparkplugs - all look ok
readjust valvetrain
same problem - airflow readings topping out at about 325 hp
vacuum leak found at valve covers
replace valve covers.
arrrrg- no diff
pull ALL the plugs - all ok except #3 - damp. Eurethra! - a bad sparkplug
replace all plugs - fire it up - idles smooth
take it for a run
1st - no traction, 2nd -no traction, 3rd gear traction till I hit 6000 rpm - where tires break loose again - yeeeeha
data log shows airflow at 3000lb/s hour at 7200 rpm-about 430 hp.
a whole season almost wasted because I was too lazy to pull ALL the spark plugs.
