Trans Am WS6 420

iTrader: (14)

I understand that this is a rather hard thing to nail down, but I was wonder on the topic, so I thought I would throw it out here for ya'll to discuss:

Taking a random 10.9 run off of the list:

10.943 1/4 124.560 MPH 1.54 60' 3480 lbs

How much MORE power would this person need to make RWHP wise to move from a 10.9 to a 9.9, assuming that race weight and 60' stayed the same?

About 150 rwhp.

150-160rwhp sounds right to me.

Meaning if a car can manage the 10.9 on motor, a nice 200 shot should have the ability to bump it into the 9's? Interesting....

if you go this much MPH = 1320= 9.900 136.926

then it takes a min of
226.4 HP at flywheel
and
199.5 Torque at flywheel

Moroso slide ruler says 3500 lb car needs ,480 rear wheel to go 10.90 . To go 9.90 -you will need 660 rear wheel hp. 180 hp

MRS 10$ slide rule from you local speed shop is a lot easier than all that figuring.

if you go this much MPH = 1320= 9.900 136.926

226.4 HP at flywheel
and

*** Forgot to mention that if an automatic trans
then approx .85 x 226.4 HP = 192.44 hp

if standard trans
then approx .90 x 226.4 = 203.8 HP

that would only be at 136.926 MPH level
