What kind of horsepower at the flywheel (and gearing) would it take to push a C4 past 200 MPH?

0ski_dwn_it

Alot! :D

I think I read somewhere that 80% of the HP after 150 MPH goes towards air drag, so to get another 50MPH you better have some serious power/*****.

I would guess that a 700-800HP motor would have enough, but you better examine your head if you go that fast or attempt to :skep:

The Hobbit

My local dealer has what is claimed to be the second fastest Callaway ever built, no 1989-010, posted speeds are 0-60 in 4.1 and 215mph. quoted horse power is 584.

If you want it its yours for 40, k GPB

It took Car and Driver a Lingenfelter built small block 427 and a smidge over 600hp to take a stock bodied C4 (with mirrors and it may have been lowered a bit) to over 200.

Zora

:skep:

scorp508

Around 580.

Rick Doria peaks around 230 MPH on around 650 HP in the Open Road Races in Nevada & West Texas....

For some reason, I was thinking that it'd take somewhere around 450 HP or so to do this - I realize weight is a big factor as well.

Jeffvette

Curtis Ward in his ZR-1 hit 201 durring a ORR event. He had removed the side mirrors and had the car lowered with a coilover setup, plus he had a top end P&P headers and somehting else. He would have been pushing close to 400 RWHP

Does that mean around 430 or so and a full bottle of nitrous set at 150? :D

Or would that detonate the drivetrain and tranny hitting the nitrous in 6th? I mean, over 3000 RPM of course.

The Lamborghini Diablo does it with 492 BHP and 428ft/lb TQ. It is a lot more aerodynamic though. http://www.geocities.com/motorcity/s...blo/specs.html

@ 3,828 lbs, it's heavier too-

:withstupid: i'd take one... :D

Wieght of the car isn't a factor in top speed, only aero.

TIMSPEED

A friend of mine runs his 87 Corvette in the Silver State Classic every year. It's basically stock suspensioned (mostly DRM parts throughout though), lowered, he's got his race weight to like 3100lbs, he has a 377cid stroker motor with a nice set of, if I can remember right, Brodix or Pro Action Lightning Heads, an edelbrock Performer RPM Air Gap intake (last time I checked), a Demon 750cfm Carb, and a nice roller cam. He drives it on the street a lot also (not smog legally ;)). I'd say that car has right around 500rwhp. He has a ZF6 swapped into it along with the factory D44 with 3.45 gears.

... of course weight is a factor - you can't say it would take the same energy to push 1/2 a ton to any given speed, as is does to push 1 ton to that same speed - even if the aerodynamics are similar – I think there’s this thing called gravity that plays into it.

Its true but its not as linear as it might seem, remember the car is already moving, but it sure takes a little more to make it go.

Are you in a rush to get somewhere?:lol: :steering:

The greater the mass, the greater the amount of energy necessary to keep it in motion.

Besides, I can’t imagine that the drag coefficiency is that much greater (or less as the case may be) between a Vette and a Lamb Diablo. That being said, the 500-600 or so lbs between the two would surly require that much less horsepower to bring a Vette (which weighs less) to 200 MPH than it would a heavier Diablo.

But then again I’m no physics expert – although I do have a theory that defines in detail the relationship between the number of Long Island Ice Tea’s I consume, and my ability to walk.

I think it takes about 550 hp to get a C4 to 200+ MPH. LPE yellow ZR1 had about 550 horse and it was kicking off 217 mph right?

weight has nothing to do with top speed. it only effects how long it takes to get there.
