All the HP in the world is useless without a good chassis, traction, and limited weight.
HP increase does not always equal ET improvements.

I've seen guy spend thousands of dollars on HP parts, only to run slower, or the same.

get it to the ground, and you'll really feel it.

The Mark VIII is "rated" at 280 hp. if you line up a mark VIII, with another car that has 280 flwheel hp, whoever makes the best use of that HP is going to run the better ET.

Find out what causes HP drag/loss, and you can go faster with less power.

HP killers?
weight
drag
reciprocating mass
friction
chassis flex
slippage/traction

...there's plenty more.

You can play with this if you want....but it isnt very accurate at all. Just calculate a loss of at least 20% loss of HP to the rear wheels. In the case of 350 flywheel HP, if it was a A/T car, you could use a estimated HP of 280(just an example)

Uh yeah that calculator is bad. It says I have 73 more RWHP than I actually do, and then says I should run over a second slower and 7 MPH less than I actually do.

I've got somewhere in that ballpark with my 3.60 pulley...maybe a bit closer to 380. I haven't dyno'ed yet to see exactly where I'm at with that pulley.

I have seen 104mph on stock tires in the 1/4. I finally got 15" drag radials so I should see a little better performance next summer if the car is still around. I ran a 13.53 letting off the throttle a bit twice and spinning off the line a tad. Once these BFG's are used up I'll be on a slick.

I need to take the car out with tires and make some passes to get used to the power. My 178hp car was much different.

The HP calculator is probably close. It says I have about 220rwhp. I don't think I have that though, probably close to 200.

it truely is one of the worst HP online facoring proggies I have ever seen.

My buddy's 70 Camaro has 975, according to that thing....he really only has about 780

sorry I even posted it...I guess it is more of a joke, than a guide.
