Absolutely not!

So the data you are using to estimate your horsepower number Is skewed and not totally accurate

90% maybe

100mph on the 1/8 shows it's a lot closer to your goal than you think. 505hp at the tyres is close to 600 at the flywheel (assuming15% drivetrain loss)

100mph at my weight is 505 at the flywheel, not the wheels

What’s the 1st gear ratio in your trans ?

1.3
1.0

Those calcs assume a clean pass with good starting line leave and an efficient 60ft time. A better start would raise the finish line mph, all else remaining the same.

I've had a few lads say the exact opposite to me, lol. I ran 125.4 mph but only 11.7, leaving at an idle with slicks trying not to break parts. 60's like 89fox (1.8)
Guys on yb said high mph because poor 60. I said I wasn't spinning, just not launching hard. Yb still say I'd drop mph, I figured it'd gain. Buddy that races a shit load said it can go either way.

Thats a foxbody @ 3280 with me, 4 speed and 4.10 rear, no tach or speedo and questionable brakes, lol. Dynoed 583hp/503 tq, changed intake and oil pan after dyno, figure 600ish hp at track

More times than not I hear that mph doesn't change much as your 60ft changes and that's exactly what I saw the other day.

I don't expect a 5mph swing because of 0.3 second better 60ft.

I need to get the car to launch properly. If I can't put down the power at whatever power it is, what's the point of fucking with timing and fuel to get more power right now

Remember, this is supposed to be fun.

Remember, this is supposed to be fun.

It's only fun when you get what you expected after shelling out $16k for an engine that was already finished 3 times.

I was accounting for shitty driver and manual transmission when I asked for 650hp. A 9.90 car will go 10.99 with a monkey behind the wheel.
