With the talk of going 200mph...

[Van B]

Nitro,

Where is the standing mile event you are thinking of? Is it Maxton? If so, the Z28 you referred to was asked to leave when he went 200 without the right safety equipment, right? Seems like it might have been one of the guys from Speed Inc.?

I see the bug has bitten you, as you have gone from not wanting to modify the stock interior, etc. to talking cage, and harnesses. I must have missed when you said what your suspension and brake mods are. All you mention is high spring rates and the biggest brakes that will fit. Any specifics?

I have said it before and will say it once more. Most of the posts I have read here are expressing genuine concern for your personal safety and that of those in the immediate vicinity when you make your attempt. If you can actually pull it off and have it documented, most, if not all of us, will think it is really cool.

High speed wheelspin would worry me a lot without a way to create some downforce. I have experienced wheelspin at around 100 mph with little more than half of your horsepower, and it was a little creepy. At twice that speed I am afraid that things could happen pretty fast if the car gets out from under you.

Good luck.

Look me up at WOW next weekend, I will be right across from the 32 Ford display and the pinstripe artists. There is a good chance that Jeff S will be there. It would be good for you to pick his brain. He has a lot of experience in high speed competition.

I'll be there all day Sunday, my son Dale will be there Fri,Sat, Sun.
I hope to see you guys then.

reminds me of This video of a subaru going 190 mph on a wet road.

really captures how fast and how much ground is covered at that speed.

I would like to try the Maxton, but It really does not matter where the event is held as the as the track is REAL flat.


I will have the car at WOW all weekend, I would love to meet up with someone and shoot the crap!!! Don't worry... from reading about me on the forums you would think I was a crazy person, I am just a guy that built his dream car and wants to run it like it's meant to be!!

Like I have said, I will see how it goes, maybe the car will be out of control at only 180 mph and I will get out and then have to sort some things out. This spring at road america I might get to attemp at least 170-180 or so on the straight to get a feel for it. In either case I have to try before I can see what happens.

My brakes are 13" C5 brakes with drileld and slotted rotors. The rears are 12 " PBR rear disc. The front springs are 850 lbs with a 7/8" sway bar, and the rear are 200 lbs with no bar. The car sits as low as posibble, I will take a pic of the new lowered height when I have it at WOW this weekend coming up.

I wonder what the red Z28 did not have that they booted him? He did not mention that.

You need a forward bar "Cage" to go over 175 at Maxton, he did not have it and went almost 200 earning him the "please leave".

I have sent in my registration for the Road America event.

I think I might have access to a radar gun to bring along to double check against wheelspin and speedometer error.

Using lake skinnies in-lieu-of the steam rollers will also help aero. The biggest thing in a non "aero friendly" body is to get it as LOW as possible. This in itself, explains the spring rate change requirement.

Sure one could push any brick past 200mph, but as it was stated in a previous post... it will require dedicated engineering common sense and more money than you have to spend, "to do it easily" as some here suspect. Its not just a "all you need is money or knowhow"... its a lot of both. Yup... you could just write a check (and we all know how I feel about checkbook writers)... but that doest manifest the experience, maturity or common sense it takes to tie your shoes.

A point that some are making is rather pointed towards aero, weight and downforce and needs to be paid peticular attention to. Spinning the wheels, even at 150mph will unsettle the chassis enough to introduce mortality. The experience gained by doing incremental events to attain your goal will make your efforts worth even more.

This whole subject is like giving a 5 year old child, with no knowledge or experience with hand guns, a loaded .45ACP. We all know the potential of killing oneself... and if any one of us could stop that from happening... we will.

I say go for it man... just do it smartly.

Couldn't have been said better.........

Nitro? Have you noticed an echo in this thread? Another thing, most of the people echoing this sentiment are people that are Gurus in this field!

Sweet.... cant wait for pics. I dig your ride and would love to see the new stance.

The only other thing I would stress is alignment settings. Caster and toe will be the things to scrutinize, especially with the inhearent bump steer that is associated with your stock subframe and geometry.

I hope to have SC&C ball joints by Spring, that would correct all geometry problems. But with the T56 setup going in, I am not sure if the funds will be there or not.

Well... not really. It wont net you any added caster, which is what you really need to increase, nor will the HOWE units impact the bumpsteer issues with the front steer system on that year chassis.

Think 6* to 6*+ caster and reducing the toe in effect of from the bumpsteer... not to mention that it actually bumps worse when you lower the chassis.
