Re: gt class question
Station wagon shipping weight is 3062. The heaviest auto gas V8 is the 327/275. It has a SS rating of 307 and a GT rating of 295 with OEM heads. I don't know which to use. Classification weight is figured without factoring in driver weight.
Quotes are from the 2019 GT Weight section. Math is mine and not under warranty....
"Shipping weight will be determined by using the power to weight factor of the vehicle with the heaviest gasoline engine and appropriate transmission"
3062/327 = 9.36 lbs per hp.
"..and multiplying the factor times the horsepower or performance rating"
9.36 x 295 = 2761 (pick one)
9.36 x 307 = 2874
"The proper class weight will then be determined by dividing this figure by the horsepower or performance rating of the engine used. Class is determined without driver weight."
2761/295 = 9.36
2874/307 = 9.36
GT/GA 9.00=9.49 lbs per NHRA factored HP
"Shipping weight of vehicle may be adjusted a maximum of 250
pounds to fit car in class."
+250 =3011 = 10.2 NHRA factor GT/IA 10.0-10.49
-250 =2511 = 8.5 NHRA factor GT/FA 8.5-8.99
EDIT
Indexes
GT/GA 10.40
GT/IA 10.65
GT/FA 10.25
