80mm 10psi - 730whp
75mm 12psi - 760whp
70mm 14-15psi - 800whp (projected with mix of e85 and ms109)

I am about to test on the 14-15psi to see where that puts us, but I am leaning toward dropping back to the original setup 8psi on the 85mm pulley for the street. Most likely I will stick with the 8-10psi on the street and then will bump to the 12-15 for the strip.

The right decision might be tied to the type of tires I have at the time and the type of event.

Nice work Russ and Ted!

When I ran the 9.93 in our Camaro with the stock LT1 I used the 75mm pulley - 70mm with your mods =

Thanks! That is great info. I have the vert and 2SS. What tires did you use to crack into the 9's? I was originally shooting for a chance to have the first vert to get the 9s timeslip.

We were hoping to get out and run with Greg's drag pack, but we are about out of time in St. Louis. I ordered the 70mm pulley today. Do you happen to know which belt I need for the 70mm?

I can look at mine to see what it is.
