After a month and a half of rain in Northern California, we had clear skies yesterday. I met my buddy Richard (ls2scooby) at Sacramento Raceway for a test and tune session. We both have 2016 Laguna Blue 3lz Z06s. Later in the day we were able to line up against each other We have similar bolt-on mods; Halltech, Borla x-pipes, Hoosiers 315x18 drag radials. I have a Granatelli tank and skinnies. Here is a time slip of our run. I wish we could have taken a video of two identical LG Z06s going down the strip with near identical times. 60's were marginal. I'm not sure leaving at idle gives the best 60'. I've cut low 1.60s and a 10.59 by footbraking with the rpms up and I'll be doing that the next time out. It sure doesn't help with reaction times! I am the car on the right.

Willie, congrats on your new PB. You guys must have been pretty much side by side almost all the way down the track. Very

Nice pass!! I bet that did look cool, two identical cars, running identical times.


Its weird how things changes as they go down the track. He had .03 on you in the 60', yet you had .05 on him in the traps with basically the same mph..

Neat stuff...cars are running damn good. Have you ran it on the stock wheels to compare the mph to the skinnies?

I know skinnies have always been worth at least 2 mph on all of my cars, I've not tested them on the Z yet.

Willie, yesterday was great fun. I bet everyone was confused about how "that blue Z06 kept running so often" until they figured out there were two of us. ;-)

Alas there is no external video - but here's my PDR from that run where I take the time at the end to apologize for redlighting you!



BTW - your 133+ mph run at the beginning of the day was a big end barnstormer! I've been combing the 'net shopping for skinnies ever since.

Great times! Congrats!!

Man, I wanted to run so bad yesterday but my car is on the bodyshop getting stripes. :-(
We had awesome air here yesterday, like less than 200DA.

Either of you guys running increased octane?
what was the DA?
Did you get the cars fully cooled down?

Is2scooby

Drag Times is showing DA at -342. I run half a can of Torco mixed with 1/4 tank of 91. I believe Willie runs a bit of race gas splashed in with his California Pump Swill. :-)

I think this might be the tail end of the good weather here so didn't want to miss our last opportunity to get some good times before 110 degree days are upon us.

I let the car sit for an hour with the hood up in 55 degree temps between runs.

Would love to see those stripes when they're done.

ACS55

Sounds like you know all the tricks!!
Awesome times!! Congrats!!
I am so disappointed that I didn't get to run this weekend. Arghh..

next weekend is projected to be warmer here :-(. Our DA was less than 200 and I don't believe we will see that again until December.

Are you going to leave it as is, or start modding some more?

Thanks Les. A video of the two clones would have been great.

Thanks ajrothm. I have always thought skinnies are good for a tenth or two at the track. I haven't run the Hoosiers with street fronts. I think Richard has a really strong car considering our near similar times and with me having skinnies and an icy Granatelli tank.

Thanks AC555, We've all been envious of your quarter mile times. I ran 4 gallons of 91 with 2 gallons of 100 octane unleaded race gas.

Nice runs and times, takes a few ingredients to get these cars to perform like that, Congrats to both of you!!

that 315 30 keeps the rpms nice going thru the traps short tire

ACS55

Yes I truly believe they (315-30-18 Hoosier DR's) help a lot. John (1QuickZ) turned me onto those, after he did all of the testing .

The help provided by members on here has been overwhelming, and I am so very thankful for that!!

i need to get out there and run my car. My chevy ss 4 door sedan is faster then my z06 found that out last night from a 50 roll vs eachother. Sonoma opens up soon so first my vett then my ss im taking out there.

2 day race this weekend. Tony. Wednesday night starts on the 15th. I told Richard to contact you for the front skinny combination. Thanks for setting me up with the front and back rollers.

Is2scooby

That's the $64,000 question for many of us, isn't it? ;-)

I'm torn. I would really like to extract the performance out of the car that I know is lurking there - but the car is only 9 months old with 3k miles on it and I'm trying to keep the warranty intact until I'm convinced that the major powertrain components are solid. That, or as some of my friends are telling me, I'm just being overly cautious (then again they're not going to foot the bill if something big pops).

Since the good weather is almost invariably done for this year, I'll probably stay at this mod level for the next 6 months or so then do a pulley, flex fuel (e40) and tune with the hopes of getting into the single digits next winter. I'll probably need a set of skinnies too...

If that setup won't get me a 9.99 timeslip I'm not sure it'll be worth doing and throwing the warranty away, as the car already runs mid-10's and is quite frankly too much for the street on the MPSS so the only upside for me is a single digit hero run. :-)

In any case, the performance out of these cars is just mind blowing. I grew up at a time when the fastest car in school bragged about running 12's but most likely could only show a 13.50 timeslip if pressed. Now we have Corvettes that can run 10's off the showroom floor. It's a great time to be a gearhead!

Is2scooby

Agreed. Thanks for all your efforts and willingness to share your results 1QuickZ!

ajrothm

This is EXACTLY where I am at right now. I want to do minor bolt ons/meth/flex E85 so bad right now its not even funny....However I also want to keep the warranty for a bit longer just because of the flakeyness of these diffs/trannies, even on stock cars. Originally, I told myself to wait two years before I would mod, now I'm 5 months, 2500 miles in and its killing me knowing there is so much "low hanging fruit" waiting there for me to get, relatively cheap..

I may try to make it a year but...for no more then what I drive it, I still won't rack up many miles even in a year or two, I'm almost ready to say F it and mod it, I may as well enjoy it when I DO drive it, and I'd enjoy another 100+rwhp...

Les

You, sir, have a sickness. Unfortunately, if there's a cure I'm not aware of it.

Mopar Jimmy

OUSTANDING ***** and Ls2scooby you guys are freaking flying on those mostly stock C7 Z06 A8 machines!!

It is also very cool to see that you guys almost ran identical et and trap speeds that is outstanding!! Based on the reaction time I assume Ls2scooby won that particular race?

Is2scooby

Thanks Jimmy! Considering I redlit Willie (inadvertently) I did cross the finish line .236 seconds before him but would have lost if it was a race. Willie is a seasoned bracket racer and I'm just a test and tune hack so I was trying to cut as much of a light as I could, but turned it red instead.

I could have sworn that I was flooring it when I saw the 3rd yellow come on but when reviewing the PDR it looks like I left when the 2nd yellow went out instead. Oh well. I'm no pro, that's for sure. ;-)

383vett

Thanks Jimmy, The .236 seconds that Richard finished in front of me equates to about 2 1/4 car lengths at that speed. Miss you on the forum. How is the monster Viper doing?
