Positron

My friends and I went to Sonoma Raceway Weds Night a few weeks ago. The black ISF hit a personal best of 12.1.

Positron

Just had a GS450 3.7 rear diff installed on my 2011 ISF on Friday. My previous best 60ft was 1.88 with 17" drag radials & oem diff.

Yesterday I ran at Sacramento Raceway. First pass of the day I hit a 1.83 60ft. In another run I trapped 120.56 mph. Will be racing again soon.

Awesome and congrats on your pb!!! A lil practice in preloading the car will get you in the 1.7 60ft club. I've managed to hit it on my last outing at the track on my last run as I was just figuring things of what to do, and after not going for a long while. You can see my slip just a few above yours. I ran on stock wheels now that I know the secret sauce im eager to try it out next year. I was having thoughts whether its worthwhile to do the 3.13 diff like the track edition rcf comes with and few other newer lexus models. I'm more in to running lapping events then drag, but will head out if im really bored.

Nice! Same exact time as my best back in 2013.

He (Positron) smoked his old record this Sunday with a 11.65 @ 120mph. I believe that’s a new NA record.

That's REAL quick for N/A. Fantastic!

I know! Crazy fast especially for launching at idle and a one legger (open diff). I’m trying to set the NA record with full interior and on street tires. My best time so far is 12.07 @ 117mph. I feel I can break it and get into the 11’s. Posted my video on YouTube.

First time making a 1/4 run. Used a Dragy. Launched at idle. Stock with the exception of 275s.

Me and Positron at the track this weekend. I did not run my fastest time but I pulled a 12.1 @ 119.45mph which is my highest trap speed till date. My best time has been a 12.0 @ 117mph.

Showcasing my friend's 2009 ISF. Hit 11s on the track and the next weekend 440+ whp on the dyno.

My personal best of 13.2 @ 108.8 at ~3600+ DA, stock tune, Borla catback, Pirelli P Zero 275/35/18, and 198k miles on the clock

187mph run from last year when the car had 177k on it.

Holy cow...no idea these were so quick from the factory!

Positron

Went back to Sacramento Raceway recently and hit 11.9 times on consecutive passes. This time I was on my daily wheels & tires setup. I'm running Lexus GSF wheels on Firestone Indy 500 tires.

Took the time to test out a new ecu tune from Tuned By Loi. This is his Stage 2 E40 fuel tune. Extremely hot day in Sacramento 2000DA+ at the time of this Friday Test & Tune event. The 12.0 and 11.99 passes were a promising start. Dragtimes DA calculator showed my car possibly could've ran a 11.71 with 0 DA. Cant wait for cooler weather this season.

Made my first few passes at a local 1/8th mile track. Launched from idle, manual mode, and tried traction control on/off without much difference. No significant spin as far as I could tell, but I was hoping for a bit quicker. Had an 8.3 in my mind as a goal, but my car has 225k miles. Track is very close to sea level and it was a cool fall evening around 60 degrees F.
