What would a dragster need to weigh with 146 cu. Inches

FED 387 · 01-10-2012, 02:16 PM

depends on the class--remember its all about pounds per cubic inch WITH DRIVER INCLUDED----TOTAL WEIGHT

Naturally aspirated.

Sounds to me like 2.4 liter could be carbed or F. I.

If carb, 2 valve pushrod, automatic-that is F/ED and needs to weigh 910 pounds with driver.

If four valve, can only run F/D, no matter what and needs to 1095 pounds with driver.

If 2 valve with purshrods and FI or EFI, you should run a clutchless five speed and needs to weigh 1020 with driver.

Thanks for the replies, just doing some bench racing and wondered.

There is a naturally aspirated, overhead valve, pneumatic valve spring, 146 cu.in. V8. That makes 740 hp and 202 ft lbs at 18000 rpm motor out there....

guessing the pneumatic spring part might be tough to get by tech

not sure about that but I do not think anything other than a "conventional" automotive valve actuated system is legal--but I've been wrong before
