I made a few runs on my local test hit road last night and finally got a couple 11 second street runs in.
The DA was around -600ft.
Car picked up ~2 mph in the 1/8 and 1/4 from my previous 7.92@94.53 / 12.02 @ 120.69 but with the same junk 60ft times.
Car was dead hooking off the line but the 1-2 shift had the tires spinning quite a bit and the clutch is starting to slip a little on 2-3 and 3-4 shift.
Going down in DA by about 2500ft picked up about 20-25hp.
Best 0-60mph with 1ft roll out was 3.85s
Best 40-100mph was 5.64s
Anyway, it was fun and the car was totally ripping last night. I need a lot more practice and I need to let a little more air out of the rear tires for grip.

how do the r888r rear tires hook?
i have r888 and they arent bad at drag launch (let down to 22 psi or so).
obviously when weather is cold (below 55) they can spin but otherwise a good compromise
The r888r hooks really well in warm temps. It was still great off the line with no burn out at 42° last night but they weren't doing too great from 40 rolls until the 2nd or 3rd hit when I was roll racing last night. As I mentioned the 1-2 shift was spinning pretty heavily but again, this is jusr a stretch of brushed concrete road and not a prepped track.

i forgot to ask is yours auto or manual trans?
Im on a zf6 with lightweight flywheel (trickier to launch).
i do some chirps (on wetted surface but not water box) to clean off tires then release clutch about 3000 rpm
slow release (which is rough on clutch) and slight steering corrections to counteract slight sideways movement.
(obviously if i get a lot of wheelspin or sideways movement i will let off and abort the run)
i want to put in a line lock to do 2nd gear burnouts (on wetted surface) vs. these hops/chirps which cant be good on my driveline

Manual TKO 600 5spd with these ratios >> 2.87 - 1.89 - 1.28 - 1.00 - 0.64
LS7 flywheel and clutch kit with Tilton 6000 series hydraulic release bearing.
The flywheel is fairly heavy, something like ~26lbs and the pressure plate and disc are ~30lbs.
When I bought the car it had a LS6 clutch setup in it that was about ~6lbs lighter.
Tires were at 24psi and they were spinning in 2nd gear from a 40 roll earlier in the evening. But again, it was very cool outside for North Texas.
Hey Krusty, keep up the good work. Practice makes perfect.
Thanks!! It seems that the power is there, just need more tire, gear and practice to reduce 60ft times. I am also wearing the TKO out and need to pull it and get 2,3 & 4 faceplated, install a new clutch and put in a bronze shifter cup bushing. The gearshift has been might floppy for over a year now as I think I broke the stock plastic shifter cup bushing.
I am cleaning out the garage now to make room for the trans removal. Then I will have to convince the wife to let me send the TKO off to get faceplated.
