Spinmonster did 200+ with a h/c LS2 C6 ~475rwhp and 50 shot in 6th gear with 4.10s...heck a C6Z with worse aero does 198 with ~the same hp as me and bet it'd do 200 with just a tire/wheel swap to narrower stock C6 sizes

 

650 horses? looks like im going to be getting a hold of a supercharger in the near future

 

Now, where are ppl going to attempt this?

I did into the 170's with a ZR1 on Road America and VIR. but wont do it again with out a roll cage and other race safty items.

Did over 200 at Darlington in a DEI Stock car 10 years ago, with tires designed for those speeds.

 

Hi Chris, I am a licensed pilot in addition to a driver. Above 200mph, you get more into aerodynamics and less into ground vehicle dynamics. I'm sure there are people who do run their cars over 200mph, but without ailerons or rudder to correct for wind caused yaw forces, I am not comfortable over about 180mph even on a racetrack. I have competed in the Texas Mile, and noticed that of all competitors, only those who run over 200mph have crashed, and this is going in a straight line on an airport runway. I have great respect for the Busa rider who ran 254.........

 

Geezes Garrett that is a scary thought right there.

and the Busa ride was just F-'n Crazy

 

.............That's what his wife said

 

I hear ya, off the record there is a 3-mile straight stretch of perfectly flat divided highway going across Lake Ray Hubbard with only one entrance/exit...My car will do 175 in the mile, but at that point you're traveling almost a football field a second and it takes another 2 miles to increase the last 20 while tunnel vision starts to happen. The car gets a little light as you can see by the bulge in the hood in video below. Lingenfelters run was with the less aerodynamic FRC and had no aero mods that I am aware of. The old runway is honestly not a safe place for high speed runs imho as it has bumps and gravel, which is what caused the cars to spin/flip because of traction issues as contact patch got smaller and they tried to apply max power.

Now the record for a street bike in the standing mile is 278. Record in the 1.5 mile is 311 mph. Both records are held by Bill Warner. There have been atleast 7-8 riders go over 250 mph at the Texas Mile. A close friend of mine that I pit crewed for went 261.5 mph.

Yes those guys are nuts... Lol

I have personally been 225.906 mph at the Texas mile on my turbo Busa. It has 235 in it on an aggressive tune up and the right gearing. Not sure if I'll ever try it again.. The new facility in Beeville is too dangerous for bikes.


Honestly I feel safer and more in control of my bike at 220+ then my Z06 at 175.. Unless the cross winds are blowing..
LSR is a freakin blast though..

 

My TBSS at 140 is scarier than vette at 195

 

Good article. HP required gets very big because the Velocity term is cubed. So a 400hp Z06 that goes 172mph needs 458hp to go 180mph.

I wonder if it would be cheaper to make a flat floor and diffuser to lower drag rather than throw money at the engine?

Here is a cool app to play with the numbers:

I don't know the mods of this particular car but if you search utube toys for tots, I was the spotter for our little group when one guy did 202, I hit 186 and backed off because of the floating feeling in the front end.

 

I'm surprised at the top end of these cars. I mean, doing 180 or more is actually an incredible feat, but with the gearing, slick body, and the power being produced, I'd think there would be more in the 200 mph range than there are.

I mean, years ago I pushed a brick of a C2 to 190 mph and they are bricks compared to a C5 or C6. I was literally at the limits, as I was revving about 7200 at that point and I just didn't have enough gears to go faster. Just as well I couldn't, really.

My really big problem was keeping it on the ground at that speed. There were many times I really felt like climbing over the windscreen and out on the hood to push the nose back down. That would only make sense to you if you ever drag raced a bike.






Here are a couple of the Kerbeck toys for tots videos.

Kerbeck's T4T 11/3/07

200 mph run (I never really see 200, 190 and 195 maybe, but the video operator is terrible.)

 

190 in a C2 would be a scary ride as I can only imagine how bad it was floating, what engine was in it?
That second video the guy in metric as the coolant temp is only 93* and rpms are way too low for 200mph, plus it doesn't look like he's going anywhere close to that when the other vette blows by him...he flips it back to standard when it shows 199* coolant temps and gets up to ~150

 

That is an understatement for sure. It is worse when you consider there is a 31 degree banking that basically slams you into the pavement, and the car still wanted to lift off the ground. A lot of what made it possible was I thought I was going slower than that.

Standard bore 427 built to late L88 specs (ZL-1 open heads), estimating somewhere around 600-650 hp.



The 200 mph run looked all wrong, and switching the readout would account for the driver's stupid grin.

 

The tach needle wasn`t even close to redline!

 

Doc my highly financed and sponsored team could not make the numbers that you ran. I raced IMSA from 1971 thru 1977, and ran at both Taladega and Daytona, but the fastest I ever went was at Taladega in 1972. Pole sitter and really nice guy, Dr. Wilbur Pickett, who drove for Bobby Rinzler came by to find out what my times were. When I told him, he suggested that he "tow you around" the next practice session. He did that and I qualified 12th OA with a speed of about 180 on the straights. I asked him if I could take the north banking "flat" and he responded "well I can, but you should work up to it!" What a leap of faith, and the speed was limited only by the scrub of my tires on the banking Some of the best track memories of my racing life....as I'm sure yours are too

 

Definitely cool pictures. I'd have loved to have run a C3.

Those scenes remind me of our days with my friend's E/Prod TR3 at MAR.

We were always amazed at what we managed to accomplish on a near zero dollar budget. Everything broke down to about $600 a weekend or less (car stuff, gas, hotel, food, registration, etc,), which was IT budget then. I had about $3000 in the 427 in '92. A friend's dad who was an old altered driver put it together while he was down here on vacation for something to do. He told my friend I had about 10 hours of life in it, but he forgot to tell me. I got about 9-1/2 before a rod broke.

I thought I was maxing out about 180. I was always comfortable at 160 at other tracks, but 180 was a rush! There is a big difference in 20 mph. If I had realized I was so much over that, I probably couldn't have handled it.

That was the day I became mortal.


Calculations were about that, but a couple of guys running GT1 told me we were all going a lot faster than that. I was staying pretty much with most on the straights and they were running 190 or more. Chassis and brakes-wise, there was no staying with them in the infield. Some of them claimed to be over 200, and they were definitely leaving me. Outrageous speeds.


One of the Goodyear guys told me that I was forgetting to allow for tire growth in my calculations. That put me in the 190 range +/- 5 mph for other errors.



That is why I watch that Kerbeck video in amazement - knowing what we did to get that speed, and these guys do it in a street car, probably with the AC on.



I always had a knack for getting speed out of a car; just no knack to get anyone to pay for it or give me a ride. When sharing rides, I found I had to run easier because if I showed up my codriver too much, they wouldn't offer me a ride again.



Every few weeks, I end up with a dream that involves racing. It never goes away. My wife just doesn't understand it. She looks at it like a hobby you try, and when you are tired of it, you find another.

 

Memories....are made of this

 

I've driven on Texas World Speedway and Texas Motor Speedway in Nascars, the banking sure makes a difference in being able to corner at speed!

 

Fly to Germany, (i was stationed there) had many WIDE open runs on the autobahn...
