Wanna Go Fast Day 1
 

Today the fastest car was the GTR Alpha Omega 208 MPH.

Re: Wanna Go Fast Day 1
 

that is fast,I wonder what it does in the 1/4 MPH.

Re: Wanna Go Fast Day 1
 

any zr-1's run Sat? What did they do? I know Paul Workman is scheduled to run his f.b.i. today I believe and others too probably. Very interested to see how the 1990's tuned Z's run.

Re: Wanna Go Fast Day 1
 

the gtr is 1700 hp and 1/4 mile time is 8.62, trap speeds well up around 171 or so...see the details in the link. top speed 238 mph gear limited it says. http://amsperformance.com/builds/ams...lpha-omega-gtr

Re: Wanna Go Fast Day 1
 

I hope all of you guys have a SAFE and fast day! Enjoy and keep us posted. :cheers:

Re: Wanna Go Fast Day 1
 

I am hearing rumors a certain 350 was outrunning some new ZR1s.....

Re: Wanna Go Fast Day 1
 

Pete ran 154 TWICE. Very consistent.

Re: Wanna Go Fast Day 1
 

Paul workman ran what with his fbi 500 hp?

Re: Wanna Go Fast Day 1
 

I ran a 143 first run. This was for a roll and w ASR ON. However, the 200ft roll was subtracted from the overall length of the course. The roll was at about 40mph. Second run was from a dig up against a Porsche Turbo. He wanted to start from a dig which surprised me given wanting turbos to spool up. I ended that run w a 139. I lifted about 200ft from the finish. It was real fun and I need a few more runs under my belt to get used to going beyond the 1/4 mile.
The Porsche on the other hand "broke" coming out of the hole. I later found out his gearshift linkage had popped out. He later ran a 140.
A number of people came over saying things like, " I've never seen an LT-5 in person." Or " I don't think I have ever seen more than 2 ZR-1s, how come all you guys are here." Sounded like some people thought the C4 ZR-1 is a mythical beast. :-D

Re: Wanna Go Fast Day 1
 

I'd say anything over 140 is moving right along. Some of the 415's and highly tuned might, like I heard on another forum that one of our cars ran two 154's, etc. do faster but I didn't realize until yesterday looking at past 1/2 wannagofast videos that it was a rolling start. That should help our cars I'd think and to hit 143 or 150 or 154 or more in 1896 net feet from the 40 mph cones is hustling right along. Man, that's six football fields to be going 2/3's of a football field every second. There's always someone faster. One GTr there has 1700 hp and he ran 208....but for our cars at their ages without turbos or superchargers to run 140 and up, I think is pretty good. I'd also wonder if a mid ratio rear end in a rolling for speed not for time would not be better to get higher total speed than a 4:10 rear end.

When all the numbers are published it will be interesting. Some of those Porsches and 6.0 liter Lamborghini's, et al, are really fast but when you are tuned to 700 hp or more you ought to be.

Way to go. I'd be darned happy with my car to get anywhere over 130 with the more or less stock nature of it. Cool that you did it.

Congrats. And....the good news....you got to drive it home and nothing broke!

Re: Wanna Go Fast Day 1
 

Yeah a 200" roll to 40 isn't the same as using those 200' accelerating from 0.
Kevin's 441 ran twin 159-160
Al's first run was at 150
I think Marc ended up around 147 but I am sure he'll chime in.
It was difficult to find a car that was running and didn't have a turbine whine to it.
The Alpha Omega GTR broke the record again today at 214. They were going at it with a private Mitsubishi Eclipse that did 209. Something else watching these cars popping chutes to slow down.
The air was great for runs but the weather sucked. It actually got colder towards the afternoon which was one reason I left after 2 runs. But I would definitely do it again.
White Gallardo running 197-199 looked like a ground missle. The acceleration from these cars once in second gear was just amazing. It sounded like a jet taking off.

Re: Wanna Go Fast Day 1
 

Sounds almost like a demarcation line between naturally aspirated and either turbo or supercharged engines today....be interesting to see what any modern 6.2 liter supercharged ZR-1's did today. Last listing of a prior wannagofast 1/2 on their site when I downloaded it the speeds above 150 would have wiped all the modern zo6's away and anything over 155 would have taken the modern zr1's listed as well so it's not shabby. But, to go more than 160 or so must take enormous power.

Still, to hustle 150 plus mph in 1896 feet is hauling the mail where I come from. I honestly could never handle 200 mph in that distance....there's no way I ever had the reflexes for things happening that fast.

Wonder how fast an F22 Raptor fighter jet taxies to rotate airborne? Less than all the numbers you put up here not to mention slower at takeoff than the white Lambo or the GTR probably and he's got a whole lotta thrust pushing him, 70,000 pounds worth at what, 120 knots or so?

good job...btw, I spoke with one member who added twin turbos to his lt5....it makes an LPE resleave job look cheap.

Re: Wanna Go Fast Day 1
 

This was my first time running anything past a 1/4 and i had a blast.
This was a great turn out for the ZR-1's i think we had 10 ZR-1's.

I was happy with my MPH could i have gone faster maybe but 1 more MPH or 2 would not made any difference to me and i do not need to break my Z to get it,i also needed her to get me back home
I tell you guys 1/2 mile sounds long but boy at 150+mph it comes up fast.

I'm very impressed with all of our Z's today we all ran very well,heck we were the only N/A cars there and running good numbers with 30 year old technology.
If they had fastest N/A street car we would've won that trophy today.

Pete

Re: Wanna Go Fast Day 1
 

Good speeds, Pete. Did you have any issues slowing down, plenty of room?

I read somewhere that a few cars went off the track and spun in the grass over the weekend. That would be very frightening to me. The place looks like it was good for the purpose on what video I saw on the Chicago site.

Way to go....and you kept the right side up!

Lance

Re: Wanna Go Fast Day 1
 

Yes, it was a thrill, for sure - even more so if you are late on the brakes [-X and run off the end of the strip...[sigh]...like someone did.:(:(

But, the good news is (I hope) it is limited to front end damage, including the hood. Looks like the end of my driving season came early this year. I'm pretty stiff this morning - lower back muscles and neck muscles are pretty stiff this morning, but other than my pride being bruised we'll both live to race another day!

My first (and only, unfortunately) run was 143.14 mph from a rolling start from 20 mph at some distance from the starting line. The consensus is that running from a dig would have yielded a better result; fortified by the experience of others that did a rolling vs. dig start. But, I gotta say, she ran real well, and "in the pack" with the other 500 packages:). We'll give it another shot next year maybe.

I held the HEART OF THE BEAST to include the results of the event, so as to include all the results. I gotta tell ya, it was a fantastic showing of ZR-1s, and they really kicked butt in the NA class! Looking forward to the final tally.

Stay tuned to this channel for photos and latest developments: dancing

Re: Wanna Go Fast Day 1
 

Glad you are okay!

Re: Wanna Go Fast Day 1
 

Paul,
You were hardly alone...here's a gtr that hit the brakes and tears right off the track to the left and the photos of what happened to it in the bushes...I saw that it came back and ran later but minus the entire front clip. Don't quite understand why it veered like that. Could be lotsa things.

there's a video embedded in a Chicago forum as well of it happening

http://www.youtube.com/watch?v=kVaw4...layer_embedded

Re: Wanna Go Fast Day 1
 

Wow, that looks like a blast. Congats to to the FBI group for a great showing. It would be interesting to have a list of your times and what gears you are running.
Just think, if this was scheduled a day after BG we could arrange tail of the dragon, BG and then 1/2 mile!

Re: Wanna Go Fast Day 1
 

And that is something to be very proud of !

Re: Wanna Go Fast Day 1
 

That GTR ran a 174b with the rear wing. They ran the car without the wing and ran 178, after the run the car went off course and spun in ther mud a few times. After a little cleaning up it ran 174 the way it looks in the photos....

Re: Wanna Go Fast Day 1
 

Pete beat the stock C6 ZR1s from what I could see, in spite of less cubes and no boost - truly amazing! I just wish I could've wagered some C6 or foreign car guy on that before the cars ran. I had a feeling he could beat them heads up and told him so last month at BG. I talked to one of the C6 ZR1 guys later and confirmed that his best was 153mph - not good enough for Pete's 153.8!

Congrats Pete! Your Frankenstein monster that sits in my garage did pretty good too. 159 & change. I raced a souped up turbo Nissan 350Z that ran 166.5mph in my first race. He had the faster trap speed, but I was way out in front of him, beat him on the square by 5-6 cars at least I think. Not uncommon for automatics with slower trap speeds to have better ETs. Too bad there were no clocks. The overdrive held up ok - no issues, so hope the new transmission mods put an end to my problems there.

I would've loved to see Al get a run from a "dig". I have to think he'd run every bit of 163+ since our setup is so similar except for the 6-speed which should be worth a few mph.

Re: Wanna Go Fast Day 1
 

Kevin,

Absolutely on Al's car. And I am even sorrier now that BobG. didn't come w the 427. That would have been a show. Does anybody recall any cars running as fast as ours that were NOT FI cars?

Anyone know if the GTR's run carbon brakes?
 

They are quite grabby unless preheated....Indy cars have this issue..It looked like the GTR that spun had a left front brake grab as he stood on them pretty hard....I was amazed to learn that the fastest GTR was running 35 lbs of boost and a 4 liter engine...

Re: Wanna Go Fast Day 1
 

For engines and cars designed in 1985 or so, that ain't too shabby, guys. Apples to apples you done good, real good. It sure puts the new C7 vette into a kind of perspective offering a two valve pushrod engine at 455 hp all these years later.

They better do a faster model asap or they are going to face people going elsewhere for more hp.

Re: Wanna Go Fast Day 1
 

Ryan,

That particular GTR from Topspeed had its rear wing removed prior to that run. I guess they wanted to see how much drag the wing was putting on the car. I guess when he hit the brakes, others watching it said he unloaded the rear and it snapped around on him.

Lance,

There wasn't one car there that would have lasted a fraction of the 24hours that the ZR-1 did in the Endurance run. They were all very fast, very high strung and likely pushed to the max. Remind me of
Roman candles.

Re: Wanna Go Fast Day 1
 

Man, I would love to have seen the two days. I don't for a minute doubt your comment about durability. My mind just keeps wandering from 1985 or so and concept and boosting a dohc 6.2 liter lt5 and wondering just what in the heck is possible with speed had they continued to evolve the platform. Looks like the modern ZR1 supercharged approach is a touch old fashioned in some ways, especially what you have to pay to buy one.

I'm happier with my 1991 Z all the time. Eventually we'll get to see some videos of the Z's running. You guys did great.

Re: Wanna Go Fast Day 1
 

BTW - the peak (lowest) density altitude for the day was 323 ft above sea-level - very good for the most part. It is about the same DA as a day in October 2011 when I was at US41 and ran my best numbers of 10.44 @ 133.0mph. Trying to compare apples to apples, if the car ran 159 in the 1/2 and 133 in the 1/4, it looks like I pick up about 26mph "on the big end" of the 1/2. Pete is about the same with a 154 off of a 129 in the 1/4. Perhaps big inch 6-speeds like Bob and Al might pick up a bit more than 26 from closer ratio gearing, maybe they could gain 27-30mph off their best 1/4 trap speeds. I'd lean towards the high end of that range because I think the quartering head wind that we had probably cost me 160+ as opposed to if we had a no wind yesterday. These guys might've popped a 165 if all went well.

Kevin,

If only it had been today dammit!

Re: Wanna Go Fast Day 1
 

What a great time. Next year we need to get more video footage.

Re: Wanna Go Fast Day 1
 

Nice run Robert. What was your speed on that run?

Lance

Re: Wanna Go Fast Day 1
 

Woo hoo. great sound !
Need split vid of road and dash.

Re: Wanna Go Fast Day 1
 

139.8 MPH

Re: Wanna Go Fast Day 1
 

Tojah the RED VETTES are faster!!! (they just don't stop as good, I guess:o)

Re: Wanna Go Fast Day 1
 

Looked faster to me! Nice clean run though. Must have been fun

Re: Wanna Go Fast Day 1
 

Paul, I'm thinking the reduced HP and additional 600 pounds had something to do with the MPH difference.
I knew my car would be a considerable amount slower. We will be working on that for next year.
HMMM, Now that I think about it. I do have a red ZR-1. Maybe next year we can bring two or three. I am sure the wife would have drove the ruby.

Re: Wanna Go Fast Day 1
 

Scott, I forgot the mount for the second go pro camera in the ruby.
GoPro was suppose to be at the event and I could not find them.

Re: Wanna Go Fast Day 1
 

Robert,
I know very little about the Callaway other than they existed. I interpret what you are saying as the model you have, Aerobody, with the design changes, body, etc. weighs 600#'s more than a normal stock ZR-1 of the same vintage. Is that correct or is the 600#'s a big Gorilla or two, Like Workman once he was out of a ride, who chose to ride along?

Lance Pearson

Re: Wanna Go Fast Day 1
 

Lance I just looked up the kit it is 200#, Plus 150# of Dynamat and Dynapad that I added last summer (which Pete was correct when he said "It looks to me like you are adding weight to your car", and an overweight driver comes to more like 450#.
There were no riders allowed.

Re: Wanna Go Fast Day 1
 

You're not going to hear any overweight driver comments from me! People in glass houses and all that! I was kidding as Paul's day got cut a tad short.

The Big Bend Open and Sand Hills races you need a navigator to give you road configurations coming up because you are driving to match an average speed you've registered as a class to compete in, 130, 140, etc. At those speeds on unfamiliar roads someone studying map and calling out approaches, "right turn 65 degrees half mile...." would be invaluable. Different things.

Still, I like your video and you did very well it seems to me.

Lance

I would like to do the Silver City run some year.
