G'Day,...............FYI

Forgot I has this cool calculator page from tciauto.com

Has your basic HP vs ET calcs (I know - everyone has their opinion on them) but what I liked was the various gear ratio/rpm calcs to optimise 1/4 times.

Yep - they can be a bit out there.

There's plenty of online E/T calculators out there - I was posting this one with reference to the other driveline calcs provided.

What numbers did you plug in anyway - they are "garbage in - garbage out" calculators.

Remember its rear wheel HP and vehicle weight in lbs.

Stock XE 351 does 1/4 in 16.3sec and 0-100 in 8.9sec........a real slug!!

Numbers on ford website for 351 XE are 149kW@4300rpm - see this link.
http://www.geocities.com/falconfacts.../xefalcon.html

The weight listed is for the lighter 6 pack. Your 351 XE (I am assuming you have a 351??) with you in it will weight about 1650kg (3600lbs).

SO......re-enter 3600lbs and 170RWHP (149kW=200HP. Minus ~15% for driveline loss = 170HP @ back wheels). What did I get........16sec ET @ 85mph. These calculators do give you reasonable ballpark figures - only if you enter correct data.

Cheers

PS: A 3600lb car will need about 450HP for an 11.5sec 1/4 mile.
