Tim Murphy

Todd was here last night and I showed him my G-Tech run and he was totally amazed that I was almost pulling a full G in 1st gear. He said he can get about .7G's with his 245 Nitto Drag radial tires. Not that the car doesn't have the power but he can't get the grip.

Then he was checking out my tires and he noticed the tires were only scrubbed down the middle and not on the edges. I guess running 35psi with a drag radial is not the smart thing to be doing. He thinks if I drop the pressure down around 25psi I will be able to pull a full G in 1st gear. Maybe I will catch the new Z06 3.5sec 0-60 after all(?).

Those tires HOOK up, big time!

FYI, mine are 275x17 BF Goodrich G-Force Sports =

Screw some bolts into the wheel, hold the tire tight and drop them down to about 10psi. Those are nice wheels, nevermind on the bolts.

You already caught the ZO6

Can the G-Tech do a 0-100-0 test? That would be cool, 12.4 from the Ford GT was the top from this test. 13 seconds is the overall average.

Cheapest car on the test is $65,690. I'd say you have the field beat hands down.

Yes it can! The key is to stand on the brakes as soon as you complete the 1/4 mile. It'll automatically calulate the 0-100-0 for you. I think I posted one some time back. I'll see if I can find it again.

Edit: Fount it! Not my best rn, but you get the idea.

Nice run tim! If I get a 5 speed some day I will be buying a kit from you.
I was in "Old and New's" Murphed 928 with 9psi and it was alot of fun!

I was wondering how the G force tires hooked up, well I guess that answers the question. I had heard good reviews of them and I like that they are streetable (I don't care if they last long anyhow).

Whats been upgraded in the new upgrade package since last years kit was for sale?

That sounds cool and all, if I had paid attention in physics class I could come up with a witty way to say that doesn't sound 100% accurate though. Since Tim will be hitting the brakes at 133mph, the amount of time / distance will be different for the 100-0 stretch than hitting the brakes at exactly 100mph. Maybe not off by much.....just sayin. Then again, the fact that I never actually took physics may show I'm 100% full of **** in this post.

Sorry... #80. I posted my 0-100-0 run there.

hacker-pschorr

Ah, I think I replied before the picture loaded.

Any, back on topic - it seams to me your car will do better than the time posted if you do an actual 0-100-0 vs a calculated time from a 1/4 - 0 run. The 100-0 time will be skewed when you start at 130 vs starting at 100. The brakes will be hotter, tires will be hotter, car is under more inertia etc... does that make any sense? Not sure how to explain it.

AO

I think the slight loss in brake fade would be more than offset in the reaction time you'd have in timing the exact moment to apply the bakes. That said, if it make you feel better, I'll give it a shot as soon as I have my wheel on Friday.

That's what I'm looking for

I should loan Murf my Pagid Orange pads for a few runs.

Part of what makes the 0-100-0 fun is how well the car will transition from full acceleration to full brakes. Be careful.

Reality check!

With respect to the C6 Z06 times, the Road & Track drivers are SLOW as other magazines are getting 11.5 - 11.7 @ 125 mph. Their 118.7 trap speed is pathetic! Their 12.2 quarter is the same as what the magazines got for the C5 Z06 which has 100 hp less.

With that said, MURF's trap of 132.59 mph will easily smoke a C6Z (..125 mph), and with some practice, MURF should be able to do a much better time than 11.49 based upon that 132.59 trap!

Man, that is smokin'!

You need to look at who is doing the testing (not sure in this case) since every mag will frequently have the assistance of pro drivers for big comparisons. The famous 1988 "Top Speed Shootout" by R&T had Phill Hill, Paul Frère and one other F1 driver on hand to do the testing. I didn't check this group, but to say R&T is slow, really depends on who is behind the wheel for that particular test. Quite often they will have drivers from Grand-Am or ALMS to help push the cars.

Not to mention some of the major car magazines have been accused of speed shifting – not lifting off the gas, letting the rev limiter hold the motor at red-line. Sure this will result in faster times, not the way I plan on driving my car. R&T used to have a disclaimer (maybe they still do) in their road tests stating they do not speed shift.

Either way this is why I like comparison tests. Temperature, humidity, track conditions etc…. all play a big part when trying to get every last 10th of a second out of a car. This way it’s an even playing field since all of the cars are there at the same time. Granted this does nothing to help compare our cars to the modern machines, it does make for a better comparison of the cars in the test. This is also why most car mags will list the weather conditions somewhere in the test.
