From 10.9 to 9.9, how much more HP needed?
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?

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
*** 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
-----------------------------------------------
MRS 10$ slide rule from you local speed shop is a lot easier than all that figuring -- E.W.J.
it only takes a few seconds to enter in computer program then click the calculate button
pasting results into this Post ..takes longer <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
