Wanna Go Fast Day 1

[kcl98]

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.

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?

[RyanChappel]

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...

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.

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.

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.

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!

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

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