A man can never have too many automotive calculators!

saturday night about 7:00 to whenever, we usually eat afterwards bring wife/kids if you got them.

now back to our regularly scheduled forum

I guess I need to take the old bus to the drags, 2 different calcs say I'm good for a 12.76
Probably with slicks though, I wonder why they don't factor gearing.
BTW the efunda bolt torque calc is bad to the bone.

342rwhp with 6psi boost, t45 and 3.27 gearing (soon to be 3.55)
nothing major. How much do these things weigh? my old 56 chevy wagon weighed 3800 and went 13.90 on street tires.

BTW, I ran the numbers on the blower calc, it's pretty darn close

I can't remember the name of the place, but right at US19 and Ulmerton on the NW corner right behind the Bally's gym, there is some kind of a shipping or distribution warehouse. I saw they had a sign that said public scale. Mine weighed 3235 with about 1/2-3/4 tank of gas and no spare tire/jack.

Only weight reduction mods that I know of are the aluminum DS and BBK headers. I even still have the dogbone on the rearend.

Woah, apparently while my car puts down 265 rwhp, it puts down 345 bhp. That's a HUGE loss throught the drive train...

Keep in mind that they're calculators, not real world stuff, but as I recall most stick cars lose 15% in the drive train, I'm not sure about autos but it has to be more than a stick.
