More slips, great reaction times last night -- Car #30 is me
Destroyed everyone I raced except the racing bike and he redlighted. The last race was against a Corvette which asked me to move up to race him. It was a c6 Z07 heavily modified, black and sounded mean but it wasn't up to beating me. He had a good reaction time and his 60ft was better. I ran this on the ByDesign/Cobb 93 map instead of the 100 map and finally remembered to turn off traction control.

Here was the fastest run
This was the fastest run the second. The first one I let off at the end and still beat the poor c5 vette that ran me but here is the second one with TC on and the ByDesign/Cobb Stage 3 100 octane map. That was a 1000cc drag bike on the other side.

So without better tires I am not going to do better than 10.6
Looks pretty clear to me. I plot RPM vs Speed from the last run against the Corvette with TC off and the 93 map.

They seemed fast to most of the other people out at the dragstrip and the announcer called my car stupid fast. I guess it's a matter of perspective but hey, when you can get a faster reaction than .0018s, make sure to post it OK? I am still running PZeros and they were at 30lbs, that's about the best it's going to get for me. What are you running now?

I've never thought of a 10-second 1/4 mile time as terrible for a street car, but I do think there's some interesting opportunity in the 60-ft. Everything else looks great except that not seeing perfect RTs at .500 seems strange. I guess they changed that (probably awhile ago). It used to be that anything below .500 was a red light. I think that the RT timer started at the last yellow.
Your 60-s are very consistent 1.74-1.76 so it seems like perhaps you aren't spinning (which I would expect would be generating inconsistency). Are you using launch control?

Nice work William. You data monster! Some days at the track are just not meant for getting the best times comparatively. With the other guys making any comments about conditions? But yes the 60 foot is what's killing you. Clearly a traction issue. Not Bad considering. Especially because we know the 200cel catalytic converter's were holding your car back. I want you to call me next week. I have an idea for you

The large HD 100s do the job in most cases. Sometimes we still need spacers just for the extra piece of mind. It's so strange because car to car and state to state it's different. Altitude and octane also affect things when you're on the edge like that. Call me anytime and I can go over all the pros and cons/options. We always figure it out

My best 60s are never much below 1.6 on the best day. PZeros just don't grip at the strip but they are OK at the track. I think I might have gotten a 1.59 once. It was in the 60s all night and humidity was 40% with a DA of 300-400. Good conditions for the engine but not that great for grip. The track was very slick outside the center of the lane on the back half of the track. My rear end was slipping on the last run and that can take a couple of tenths off when that happens but I stayed on it and beat that Vette. As always, there are faster pro cars but not many ten second street cars much less on street tires. Mostly the faster cars are sub ten second and the rest of the pack runs 11+. The supercharged CTSV runs tens with NOS but he is about the only other car that does. The rest of the sub 10s are not street cars.

Well, with different tires and a 1.6, that run against the superbike would have been more along the lines of a 10.4-10.5, I would guess.
Either way, that 134.9mph is spectacular and the car is clearly really really moving. I don't recall too many 991 TT's running faster.

You should be able to get 1.5's with the R888's. There is a 315 30 20 and you can drive it on the street as much as you want. A little noisy but the idea is you could drive to the track with it and run the Perelli's in the front. Decent price as well on tire rack. 10.3 is like a brick wall with any car. Things need to really start getting technical to do better and stickier tires are a must. No matter how much power you have as we have seen.
