200 to 250 is something...
250 to 300 is something else.

I think the most gains can be relized through aero tweaking beyond 200mph. The power requirements vary big time depending on the object you're trying to propel to 300mph.
A corvette may take only 1.5kHP but a Bus would likely take around 7k. Dont underestimate wind resistance!

Veyron has 1001hp and does about 253mph. I would imagine based on aero, it takes exponential HP to increase top speed, so 300mph in a street car might take 2000hp or more?

Isn't there some stats on the Salt Flat classes for stock type cars top speed?

The faster you go, the more mother nature tries to hold you back. Aerodynamic drag increases exponentially with speed. It takes the Bugatti Veyron 250hp to hit 150mph. To get the next 100mph (250mph), it takes an additional 750hp.

Based on my Car calculator for the Z06, you would need approximately an additional 900 horsepower (give or take) at the rear wheels to make it to 300 mph (presuming the car stays on the ground, doesn't fly apart, yada, yada, yada...)

So what does that mean at the crank?

Maybe the answer is in the torque, not so much the horse power.

I have semi rigs that only put out 600 horses, but have 1,850 ft.lbs. of torque.

Correct.

When the discussion of extreme top speed arises, most people become fixated on the power/torque output of the motor when AERODYNAMICS is crucial :yesnod:

The Corvette body's shape is not capable of 300 mph without MAJOR structural changes to improve CD, decrease drag, raise downforce, and increase rigidity (lest we forget that a tire capable of 300 mph friction increases and sidewall dexterity would need to be created).

In short . . . you could make all the monstrous horsepower necessary, probably well north of 2000 bhp, but the Corvette would most likely lift or be ripped apart from the wind shear before it returned to Earth.

Even if it is possible...would you really want to go 300MPH in that car...tire blow out...lift..ect...I am sure the odds for something to go wrong is very high...

LPE / John :sadangel: tried to set a record with a stock bodied car at 300 MPH he got close in the upper 290's so it can be done. Not sure on the power he had.

You guys make it seem like 250mph+ is "dream land" and thats cars will fly apart and need 5,000bhp - take a look at some of the 250mph jalopies that run at Bonnieville ;)

It looks like all you need is a decent V8, some smooth sheet metal, a couple rolls of duct tape and an old picku[ truck as a pusher - hehe

ya........not happening

ya........not happening

All the horse in the world cant beat physics

SORRY JASON,THE CAR DOES HAVE CATS WHEN WE RUN IT ON THE STREET AND IS STREET LEGAL.............WHAT POWER LEVELS HAS KATECH MADE WITH A TWIN TURBO LS-7 ENGINE???????? I DONT RECALL SEEING ANY.THANX!.................NORM :D:thumbs:

I believe Tommy has been 200 MPH. How many others have? I was clocked at Daytona on the back going into turn three in 1990 in a Camaro at 228 MPH (Did not use the stupid bus stop). It not only takes a few good size balls but you have to be a little nuts! You guys can have those 250+ MPH runs. Mine are not that big and with age they have srunk! ;)

The biggest obtacle to hitting 200 mph in only 18 seconds is spinning the tires. I cannot imagine a car able to accelerate that fast actually hooking up without all wheel drive. I'm curious as to what tires it had. I think it was Road & Track magazine that couldn't get the 770 HP Lingenfelter to hook up in a test earlier this year. The 1/4 mile et was actually worse than a Z06.

Its the tyres and the clever boost control/traction control LPE employs that allow fo rthe insane launch speeds.

That car is a badass car through and through. A friend of mine was the photographer/videographer for the record runs - and he said in person that car is out of this world.. literally.

Norm - I love it :)

Since we're kinda all preaching to each other... let me toss in my pretty penny :)

There are very many forces at work at such high speeds.
Sometimes a LOT of work goes into things that look worthless.
"Jalopies" will get you killed! I'm not saying that it takes money to go fast (ok wait - it does :rofl: ) but there are very many things to consider.

For example:
Without a "weighted" front to "lead" the car at high speeds, second order aerodynamic forces can upset the balance at high speeds and suddenly you'll be going sideways at 250Mph. Not cool!

Sometimes you'll see these "unexplained" wrecks on TV during these high speed runs. A lot of times its aero related, or something they forgot to account for.

It takes a lot to go 250+ (relatively) SAFELY. Anyone can slap a big engine on a bike and go fast.

Woah. I stand corrected. I meant no disrespect Norm. We have a great relationship with Lingenfelter and my post was not meant to imply anything competitive.

My most sincere apologies,

MUST have Cats for a street car. Deal with it.
 

Hate to go back to this but Jason is right. No Cat's = NOT a street car. I saw that standing mile thing with the Hennesey Viper and the Veyron and the LPE car and how they were all street cars. The Viper had no catalytic converters, it wasn't a street car. I love all the people who think this is a nothing issue, come out here to CA and when the cop looks under your car and impounds it when he doesn't see them see how trivial it is. They are now giving all the cops classes on how to look for these mods and to hit the car with the book if they don't meet the specs.

It's silly as hell, ok, them impounding tons of Honda blingmobiles for having colored intake pipes is funny, but beyond that its kind of scary. It's like C.A.R.B. when the cop is looking at your car, frightening to have someone who doesn't really know what he's looking at about to make a decision that is going to cost you a lot of potential time and grief and money.

JASON,NOT A PROBLEM!KATECH HAS AN OUTSTANDING REPUTATION BUILDING WINNING BULLET PROOF ENGINES! :cheers: :thumbs:

Well look who has spoken!!!! I guess the Alley isn't providing enough entertainment for you!!


Jk Norm. You have the baddest Z06 in the country (least in my opinion) From talking to Jeff over emails its really amazing what you have done with the car. :thumbs:
