Thanks. This article is good if you want to calculate how much HP is needed just to overcome drag at 250. For the corvette that is illustrated, I remember calculating something like 670 whp just to overcome wind resistance. Now factor in tire resistance, drive train loss, etc...

Yes. This assumes the two cars will make identical runs under identical conditions but only with greater HP. The proportional rate of change in HP for both vehicals will need to be identical. To a first approximation, let's say they are quite similar, otherwise you probably need a supercomputer to figure out all the different input parameters and outcomes. 
This is for for exactly one mile based on the stated hp number and speed recorded at the one mile point. If you do the same calculations for AtomicZ, using 732 and 206 as input parameters then his car would need an increase in HP to 1308. Is he somewhat of a novice driver?
You see this shows the real life situation you were talking about. But the numbers are within the ballpark so to speak.

I agree with you that the real-life HP requirements are far different than the calculations may imply.
Thanks for your time.

AtomicZ is actually a very good driver. He's actually a skilled roadcourse guy, and I belive he has the best Standing Mile mph numbers for any Porsche near his relatively low power level.

PS. If we all had electric motors, these numbers would be a cinch to calculate. It's the complexity of the internal combustion engine that makes it interesting and fun and in keeping with the human element.

I have a feeling that this is the case. EVOMS has two other cars that ran the TX Mile, both making 'over' 900 whp. One went 218 and the other 215. Very fast cars...
AtomicZ's numbers are definitely not over-rated. He ran a 5.55 60-130 and trapped 143 in the 1/4 mile, all indicative of a 730 whp GT2.

Yeah, you've got a treasure trove of data. Just by eye-balling it you can see the trends. Someday when you have the time, you can plot all the data, do some statistical analysis, see the outlyers, and perhaps some interesting trends would arise that you wouldn't see otherwise.

Congrats to anyone running 200 mph or more. Evoms is the king of the hill for right now.
I am sure they or someone else will eventually get a Porsche to 250!
Looking forward to seeing the results!

1048 hp needed to reach 230.
1345 hp needed to reach 250.
The nice thing about this method of calculation is that it's relative to the dyno that was used to measure the initial HP. As long as one uses the same dyno to measure mod increases and the calibration doesn't change, the % increase should get you in the right ballpark which is why I think the Evoms car has a decent shot at 250 with the 1200 hp target.

No, I mean how much power it takes in the real-world. Not on paper.
Thus, we'll just have to agreee to disagree. I don't believe any normal street car will ever hit 250 with only 1200 HP. Not even with pixie dust sprinkled on it...

Obviously Todd Z has quite a bit of real-life experience too with these cars. It is he who thinks the goal of 250 with 1200 hp is a challenging but realistic one. I just provided some calcs to verify that it is possible based on his previous numbers.

One more data point:
Eddie Bello currently holds the world record for any street Porsche in the Standing Mile. He went 236.6 with over 1200 rwhp (I believe 1,229).
He also happens to be one of the best, if not the best, straight-line Porsche drivers on the planet (he also holds the street Porsche world record 1/4 mile time at 9.17 @ 161).
My argument has absolutely nothing to do with the tuner, the make of car, or the driver. It has to do with the fact that in the real-world, hitting 250 in a Standing Mile takes a lot more than 1200 HP, regardless of who's HP it is.
