Re: 650+HP BBc
Vintage, you need to look at the whole thread over on that site.
Star Racing George Bryce:
"Torque..is not because of stroke , bore or valve size.
It is from "trapping" ability....
If we trap more mixture and light it..it will make more torque.
Some good examples....
Our 528 Hemi makes 670 lbs feet @ peak = 1.26 with street cam
Our NHRA 160 cube twin makes 230 LBS FT = 1.43
Our Suzuki 1750cc (106) cubes makes 160 lbs feet = 1.51
Guess which motor has the shortest duration cam?"
AND
"I want to add...all of my race engines operate above peak torque...like the 160 twin, we run it from 9000 to 10000...we never see peak tq.
We run the Zook from 12000 till 14000...both of them have peak torque below our racing range.
The 500 inch PS NHRA engines run way higher up than where peak tq is also.
ALL engines have the same horse power and the same torque at 5252 RPM.
Well designed engines have more Torque below 5200 rpm than the HP.
AS well designed engines have more HP than TQ after 5200 RPM.
More teasers"
Now notice what George said above last line, "Well designed engines have more Torque below 5200 rpm than the HP.
AS well designed engines have more HP than TQ after 5200 RPM." Is that not EXACTLY where this 468 make the change to HP being higher then Tq.
