before yall raise the bullshit flag, no i did not beat that frikin' monster. i wish but no.
i was was crusin' up the turnpike going to my house when i passed a blue zo-6, i was awh-shite this guy is going to hand my ass to me on a silver platter.
when we left the okeechobee toll northbound it was on. i kept my car in third waiting for the pounding sure enough i see the beast crawling behind me little by little. when he got next to me, i stomped and shifted it into fourth, he was walking me not to bad but walking me. i didnt give it up we were upto 150 mph the vette infront and me trying to save face about four-five cars behind.
i kept on pushing the car and hangin' with him, when we got over the okeechobee exit the is a miami dade popo on the side of the road. both of us slowed down but nailed it again. the cop was on the emergency lane and blacked out. no lights in the rear view so we kept going.
i was next t him when we got caught up in traffic we were in and out and i was happy to be next to him and the it happened.......the open road. that thing just took the hell off. i was going an idicated speed of 160 mph on my speedometer hitting my rev limiter at 7000 rmp. the vette just got smaller. i didnt give it up though i was pushing that spped for about 20 sec when we came up to the big curb going north on i -75.
i caught up to him there again. we were doing 105 on the curb and i was hangin' with him. when on i-75 i was ready for him like a scared skinny kid about to run away from the schoolyard bully. i guess he got over confident cause he hung back and nailed it trying to pass me. when i saw him coming hard i went down into fourth and rode it all the way to the 7000 rpm limit. i was neck and neck he was not pulling on me we went up to about 130 mph, and he had a car infront off him and slowed down that was my chance to nail it and i did i hit about 150mph and was happy he was gone till i look in the mirror and he was about a foot from my rear bumper:eek: holy shite i said so i moved over and kept the throttle wide open and we were neck and neck again. we were doing about 120 mph in lite traffic, i know stupid.
i finally reached pines blvd and slowed down to get off. i lowered my window and gave the guy a thumbs up. and flashed my high beams as he went by he did the same and gave me the four ways. that zo-6 is nothing to play around with. hell i was just happy i was keepping up with him.sorry so long:mad: i need more power!!!!!!:biglaughb :biglaughb :biglaughb :biglaughb

Nice story!

Sounds like he might have been modded slightly. I know E36's are aerodynamic bricks at anything over 100-120mph, but you should be putting down enough power that he wouldn't blow by you like your story suggests.

Z06's are stupid fast though, in just about any test of performance.

Huh... With all your mods, shouldn't you be able to beat him?

I agree with Def, this car must have been modded. I know, I know, they are scary fast, but with your impressive list of mods... Let's just say you're being too modest when you say that «this guy is going to hand my ass to me on a silver platter.»

The outcome is logical in a way, but I'm guessing that on the 1320 ft, it should be close.

Hell, Dave beat a Viper and frequently (if not always) beats his neighbor's Z-06 in his SCed Z3 3.0...

Nice run, props to you guys to keep going at such frightening speeds. I know I would have back down past 140...

Dude a 240 hp S52 M roadster/coupe is as fast as an E46 M3! I'm not bragging, just trying to prove that the Z platform robs less HP from the engine, and is lighter to boot...:buttrock

My 95 M3 with SC was as fast as an E46 M3 too! And that thing made 293 RWHP! It was odd...

Hugo
07-28-2003, 10:13 AM
Perhaps, but Dave has a SCed 3.0. We're talking about a SCed 3.2 with a hell of a lot of other go-fast mods. But I agree, an M3 is heavier and its platform robs more power.

There's no way a blown M3 can be able to hang with a Z06 who knows what he's doing...they are high 11 second cars easily, with nothing more than a 2.0 60ft. They trap 118+ ALL the time. I have yet to see a supercharged M3 trap anything more than 112.

A C5 you can take with a blown M3, but not a Z06 with the right driver.

Nice run nonetheless.

A modded Z06? No comment.

What a lot of people don't seem to realize is that Dave is a special case. Hes a drag racing don. Not many people have the skills to launch as well as he does.

Given a very fast and capable car it still takes a good driver to showcase its performance. That being said a good driver cannot defy physics.

2002 Z06 Power to weight ratio 3100/405 = 7.691

Daves Blown Z3 Power to weight ratio 2970/359.74 = 8.255

If Dave were to race himself (or a better driver) driving in a Z06 he would embarass his little Z3.

This same kind of argument goes on in z06vette forums all day with Viper/Z06 kills.

Physics doesn't lie.

Wow, the Vette is light!

What I meant by the «Dave» analogy is that when you take into account 0.2 additional liters of displacement, rabid's M3 must be pretty darn powerful.

Hugo, keep in mind that my "kills" over Jimmy's 2001 Z06 were measured in tenths, as in about .15 in the 1/4 mile, and he still had traps about 3 mph faster than me (which is indicative of his power advantage).

And my Viper "kill" was a street race, I have no idea how able a driver her was, but he got sideways on shifts, and even still I managed a nose on him, me with a perfect launch, etc...

I appreciate the comments about my skills, etc. But keep in mind, my car's 2970 lbs included my 205-210 lb ass in the car, too...

Hugo
07-28-2003, 02:33 PM
I know all that, I'm just saying that I wouldn't be surprised if with all those mods, his M3 was pushing close to 400 hp. I mean, Phil had close to that, right, and at the wheels IIRC? So, yes, he lost, yes that's the logical outcome, but it shouldn't be a total rape like he himself expected... unless his power output at the wheels his really, really low compared to the Vette.

Z06's are notorious for dynoing closer to 360-365 rwhp, meaning that 405 bhp rating (for the 2002-Present) is highly underrated....

Jimmy's dynoed around 355 rwhp, rated at 385 bhp...

E36's aerodynamic drag coefficient is 0.32; the Z06 figure is quoted at 0.31. Not quite Lexus slippery, but the E36 is hardly a brick, wot say?

Z06's dynoing 355-365hp:
Seems like everyone learned a good lesson from Ford's & Mazda's debacle with the unsupercharged Mustang Cobra and the Miata pushing out less than quoted numbers. Lawsuits ensued (sorry couldn't resist). Ford and Mazda had to pay (compensation, retrofits, extended warranties, etc.).

Note how the new supercharged Mustang Cobra is rated at 390 crank hp. They regularly push out over 360 stock hp on rear wheel dynos across the country. The Mustang mags report that simple intake and exhaust mods on these net ~30 rwhp, if not more. Heh, heh. Lesson learned.

Not exactly, I don't have much more weight to cut out of my car without taking away from it's "daily driver-ness"... As is, it's likely around 2885 lbs track prepped... I can shave another 30-50 lbs without getting ridiculous and spending a fortune...

The regular C5 has a Cd of 0.29, so not sure why the Z06 has a slightly higher one(notchback, air vents?) - but yes, the E36 isn't THAT bad in the Cd department. The thing that kills it is the large frontal area. Since drag = Cd * Frontal area, the E36 is making much more drag than its slightly higher Cd would suggest. It definitely adds up above 110-120mph.

ive never raced a vette before yet alone a zo-6. all i know about those cars is what i see and hear and they are one hell of a car. i really dont know what im dynoing now but when i go the supercharger i was at 282.6 hp at the rear wheels and 262.4 lb/ft of torque. that was before the reprograming the ecu(tweaking it some) and the headers.
the zo-6 definatly had aftermaket exhaust due to the fact that i can hear him take off at 120 mph over the windnoise and the s/c. i dont know much about them maybe in stock form the exhaust is loud as hell?
well im going to a/a tommorow to get my car serviced, hopefully the dyno will be up and empty ad can run it to see what im making now. ill keep yall posted.

That cd*Frontal area thing isn't too accurate honestly.

Ummm... that is the DEFINITION for aerodynamic drag of a body. These components, when related to speed(drag goes up with the cube of speed, so V is third order here) give you the total drag force.

The accuracy depends on the initial measurements of the Cd and Frontal area of course, but it is dead accurate as long as flow stays laminar and attached. If the airflow does drastically change around a car, things like this go out the window, and the car usually wants to start flying!

I went up against a Z06 not too long ago.

I pulled up next to it and saw two Coolio looking types giving me the "yeah...whatup look". I smiled looked the car over and gave them the thumbs up.

They nodded their heads slowly approving of my car also.

They looked away and I couldn't get the driver to look over and see if he wanted to go at. So when the light turned green (this was like at 2:00 am with no cars in sight) we both took off kind of slowly but I left it in first gear thinking he might want to go. Hearing my engine I rev...I suspected he felt something was up.

I should have gotten the jump first but I let him get the jump and dang....that things gets out of the hole mean.

His car surged forward by about a car and a half...I quickly stomped on it in first gear going around 20mph.

He was in the left lane and I was in the right. He has to shift a little before me (I pretty much took it to redline) so I gain slightly but when I shift I lose what I gained but don't really feel I lost any....then winding out 2nd to 3rd he again of course has to shift before me and I start gaining again ever so slightly only to lose what I gained when I have to shift (again red line) and lose a little.

As 3rd gear is winding out...I figure he shifts again as I gain slightly and can truly appreciate the high revving M3 motor. At this point I figure I am approaching close to 90 to 100 mph but not sure because I was focused in on the tachometer and the road ahead of me. I was nearing 7,500 rpm. At this point I let off and the Corvette let off also. It seemed both of us knew around the same time that it was time to back off.

I was kind of surprised how close I stayed. Him and his passenger didn't look all that big. I would say around 160 to 190 pounds. So it really should not have been a weight issue. Should it?

I didn't get a chance to give them the thumbs up as the fwy onramp was fast approaching for me and they continued to go on the street.

Please no flames...I know street racing can be very dangerous. This was at 2:00 a.m in a very deserted area.

On another note...I raced a Mustang GT up a hill and I beat it similar to that of how the Z06 beat me but perhaps a little more so. I was kind of disappointed that the M3 could only slightly beat this car. I was looking in my mirror and dang he was keeping up. I think the Corvette and the passenger felt the same way when I was right there.

Anyhow...that's my story :)

Rod, there's a good chance that Mustang wasn't stock, perhaps blown, etc. When I had my 99 GT I raced my neighbor's Z06 a few times, it was truly an exercise in futility, no comparison whatsoever...

A. Flow around a car is anything but laminar.

B. The Cd* frontal area thing usually only realates with any accuracy to symmetric objects, such as cylinders or cubes, flow around a more complex shape like a car is much more involved. Aerodynamic drag can be split into three types; form drag, parasite drag, and induced drag. What you're talking about is form drag, or the drag on something purely due to the blockage it creates. This is only a fraction of the drag on a moving vehicle. Parasite drag depends on how much surface area a body has, while induced drag depends on how much lift that object is creating. The main funciton of spoilers (not wings, mind you) on cars is to cut the lift on the object, not soley for the sake of grip, but largely to cut the induced drag.

Silverstreak:
Yeah that's true but I didn't hear the supercharger. A little later on I actually did come up against a supercharged Mustang. We were lined up at a light but he was on the phone. I gunned it quick and he soon followed. I could hear the supercharger. :eek:

There was too much traffic in front of us. So each time I stepped on it...I had to slow down....then he would creep up then he would slow down.

He rolled his window down and so did I and he asked...you weren't trying back there either...right? I said no...and he said he wasn't either. I said ....believe me...I know you were not trying. I asked what mods he had. He confirmed the supercharger and other stuff. He said 450 to the wheels but I don't know.

Anyhow...the Mustang GT I raced previously did not have that same sound. The other Mustang guy was pretty cool too. He gave me the thumbs up and was almost laughing as he had a big adrenaline rush just like me :) He gave me this look saying...dang your car is fast...I just couldn't catch you. I gave him the thumbs up too and we went our separate ways.

Rod, possibly a 99 or 01 Cobra... they ran low 13's stock, and 12's with some mild mods... they look similar to the GT's, less distinctive than the 03 s/c'ed Cobras, etc...

The Cd of cars if found by empirical measurements. I'm aware of the different "types" of drag(although I've heard what you term "parasite" drag as pressure drag, FWIW) - but assuming the induced drag to be roughly equal in a passenger car of similar dimensions(it usually is) - then you can approximate the differing magnitudes of the "rest" of the drag by comparing the Cd and the frontal area of the two cars.

You're arguing over a bee buzzing around your head when an elephant just took a dump in your living room, or however the saying goes. :laugh

Parasite drag is the drag caused direclty by skin friction on the body. "assuming induced drag to be relatively equal in passenger cars of similar dimensions" which an ///M3 and a zo6 are definitely not. I'm not saying you're wrong, just saying that in aerodynamics, frontal area isn't nearly all it's cracked up to be.
