Dynoed my car after the Texas Mile.....I'm a happy camper


Ray's car was closer to 19XXWHP spinning on the dyno
 
so, just for fun I calculated how much horsepower to run 300. Answer = 1250, based on a Cd of 0.34 and frontal area of 16ft. But this is assuming unlimited distance to hit terminal velocity. Now, as Jason says, to run 200 in the mile actually takes around 750 hp and this is about double the 'steady-state' calculation answer. When he ran 224 he was putting out about 1050hp, which again is about double what the steady-state calculation says. When Peak Completions ran 267 steady state tells me he'd need 870 hp, so I'm guessing the actual output was around 16-1700?. In other words there is a correction factor of 2 needed in the steady-state equation to reflect the need for the required work to be done in the time available during a mile run (of course this is a real ballpark empirical number). Therefore it looks like you'd need 2X1250 = 2500 hp to reach 300 in a GT in a mile. Amazing what boredom in the office can produce isn't it?

It would take @ least 2400rwhp togo 300 in a mile. IT takes about 1400rwhp to go 250 in the mile in a GT and alot more togo 267......
 
Wow! 1900 rwhp = 272 mph using the equation, so that's not too far off - about a 2% error on speed. Still makes me think 2500hp minimum needed to break 300 in the mile. I guess the pulley you sold me won't cut it? Actually, if the pulley and tune gives 625 rwhp, that should be good for a 188 mile per the equation - do the facts bear this out? Looks like I gotta go with the 4L Whipple if I want the T-shirt

I went 187 with a pulley and tune (610 rwhp) with a crosswind and 195.5 the next day with a 25 mph tailwind.

I wonder why the Gallardos with 1800-1900+ are only going low 240's to 250.1?
 
good question Jason. The Gallardo has the same Cd and a little less frontal area so it should have a slight edge against the GT if all other things are equal. Maybe its a gearing issue? Are the TT gallardos maxing-out before the lights? They should try a taller tire - 3% bigger equals about 10% more speed if they can pull the same RPM through the mile timers. Of course it could also be the God effect - as stated earlier in this forum, we all know God drives a GT - surely that's good for a few MPH? What would Satan drive - a Viper?

Have you seen how violent the gallardos are with that much power? They can not have that much downforce or its something with weight percentages? Maybe its the v10 and the torque they make down low, IDK I believe the Ford Gt is the best mile car period. After seeing what Ray did with his car. Looking at the vidoes of it, how smooth it is, how much power it sticks to the ground and only being rwd aswell. If you wanna be the fastest in mile racing your 1/4mile program is going to have to be there aswell. The gallardos with that much power do not look like they run well to the 1/4........ Just my opinion and observation

The highest HP they advertise on their website is 1500 HP for the bargain "starting" price of only $109,000.

and there is this additional disclaimer. *2004-2008 Gallardo with E-Gear Transmission requires additional upgrades with extra costs Wonder how much "additional" costs are involved?? :ack


Wow, I did not realize what a bargain our TT's were. :biggrin :cheers

Perhaps Jason or I was not clear, skyrex. There is an annual TT payment due and it is computed based on "realized value." To be fair, the payment increments with each documented pass over 200MPH. You can send the keys to the house anytime.....

Yeah just look on the back of the Dyno sheet for it :lol:lol:lol
