Mike,you are reading it wrong the topic is 250+ but I said he wouldn't go 240 + with the power he has. So let me get this strait you are saying this car makes 300 more wheel than 920?????

 

Ok i see the Ultimate Goal is 250mph but short term is 240+ which your saying it cannot do.. And yes the car makes ~1200whp.. which is ~280whp more than the 920 it had when it ran 231.. so do you think with 280+whp it can or cannot do 9 more mph???

The car made 980whp on my dyno barely making a 1/2 pull.. I forget the RPM it cut off at but soon as it hit full boost and TQ it spun the tires.. I couldn't get it to hold the full pass on the tires it was on.. The power curve was climbing straight up at 980whp..

I dont think its fair to guesstimate what it will and wont do if you dont even know the HP.. right??

Mike

 

I think it took about 1600+HP at the wheels to hit 250.1 in the Underground Racing Gallardo Twin Turbo.

 

Well that changes a lot....all I heard was it made low 900's and trapped 146. That's why I asked the simple question what do you plan to do for power. I would love to see what that power band looks like. Todd would you mind posting a chart?

 

Ok well the way the question was asked i assumed you thought 1200 wasnt enough as its pretty common knowledge what this car makes..

Mike

 

gotta get up to the supras levels at least, lol i just had to talk a little s**t.

 

Here are the details on the engine build:

https://www.6speedonline.com/forums/...ls-inside.html

Attached is the dyno. The dyno does not tell the whole story about this engine. Once we get all of the components installed, we will be spinning it to 9000 RPMS. Right now we are cutting it off at 7500 RPMS. We will not have all of the other components done for the mile but we will set the rev limit to 8000 RPMS to try and achieve our top speed goal.

 

Who is going to drive it? I will be there to watch this madness.... good luck! There will be some crazy cars from what I hear? UG is bring some brutal beasts, I hear the twin turbo Ford GT is coming, hmmm can not forget the original beasts... Supras. It should be entertaining.

dont forget Eddie Bello's Porsche!

Love to see the P cars running 240+

 

All of the Supras have done it on the stock gearbox / ratios as well. With a custom trans setup and more power there is definitely more room on the table for more MPH, just a matter of someone willing to go out there and do it.

I'm anxious to see EvoMS and other Porsches step up to the plate, at the same time I like seeing cars run out there with what they brung, rather than mile specific gearing, etc and 1 trick ponies.

 

that 250mph is a pure ***** number.
props to whoever gets that number done, in whatever car they are in.

 

Power (p) is proportional to velocity (v)^3. So a simple back of the envelope calculation assuming same conditions, car, tires, etc...to reach 250 mph, one would need 1179 Hp. It will be close. Improved aerodynamics and less weight will help. Best wishes.

p1/p2=(v1/v2)^3; p1=930 v1=231, v2=250 solve for p2.

 

That's to maintain 250 or reach 250 from a standing start in 1 mile?

 

That's to reach 250 in one mile based on the performance numbers from the previous Evoms car. If you just want to know how much power you need to overcome wind resistance at 250 then you need to know the coefficient of drag, frontal area, etc...and plug it into the Force equation. The article by Brian Beckman, Physics of Racing is a good one.
