The slip. Running R888’s

Thats amazing!

At 3400 lbs and 325 whp is like a 12.65 at sea level.

So either making more than 325 hp, less than 3400 lbs, or mineshaft (neg DA) conditions.

Most calculators say 385 whp at 3400 lbs is 12.05 ET at sea level.

1.83 60' must be low diff gears or lightened up car,,,Great Run! :eek:

That is the R888r's. They are sticky.

Jnaut has a much better 60’, same mph, and goes 12.24.

Doesnt make sense.

Perfect comparison... Auto vs manual...auto wins

He also blistered the 1/8th ,,,almost like it had a snort off the line :ugh2:

Just to keep this alive lol.

Went last friday night. Car is the same except I added the Z1 2 piece rear rotors.

Getting to be a bracket car!

From 12.85 to 12.95 all night long!

Good weather last Friday night. So I went back to Thunder Valley again to try and improve on the 12.85 from the previous Friday.

Place was packed with cars - over 300! A few street outlaw guys there running for the track list program, and a pile of real street cars. Track got really slick and the staff had trouble keeping up with all the people.

Anyway, ran a 12.82 with a 1.979 60' time. Hauling the mail @ 111 mph!

Previous best 60' is 1.922.

Remaining runs for the night were worse..but no question I can go 12.70s if I improve the 60 foot time.

Looks like first post hasn't been updated since 2015, and "Tranceformer" hasn't been online since 2016.

MODS! Can someone take ownership of the first post and get it updated?

Well the heat wave is over, and a cold front blew in so I wanted to try some runs on the Z.

They cancelled the Friday night fun and grudge due to wind, so I figured I’d just go run the regular Saturday Summit bracket program. At least I could get three runs in on a semi prepped track.

Car ran well in footbrake class, won a few rounds and had a good time.

Best run 12.87 with a 1.98 sixty - car was heavy and full of fuel.

I’d say that second slips trap-speed would have to be the best run :ugh2:

Thats nuts!

Not sure how that happened, but its a NA record !

Went back to Thunder Valley today. Great weather in OKC for racing.

56 F no wind, and really dry air. 600 to 800 ft DA!

The 370 loved it, and the slips proved it.

Drove it down there, about 60 miles from the house, drove up to the lanes, and it ripped off a 12.66 @ 110 mph.

1.92 - 1.96 sixty foot.

Very pleased - only change is aam 3” dual exhaust!

Previous best was 12.82 earlier this year with Ackrapovic exhaust.
