23 celcius
wind not helping
20 kmh a bit in the face and sideway
first time i was trying it with ppe headers with high flow cats
check engine is on and traction control no longer works since installation ill have to look at this problem
best time before ppe headers was 13.44 but in very good condition little wind in the back
ppe header only help on the 60 foot( today 1.94 once and multiple 1.95) (instead of 1.97-2.00)
i also have ultimate coldair intake ( true cold air) on it and first gen fsport exhaust
19 inch rims aftermarket 265 rear
ill try it again next week its getting colder here
Well, some use the rule of thumb that what you run in the 1/8th mile AND then tack on half of that time onto it to net your estimated 1/4 mile time. If I do that, I get a 12.97-12.98 time, according to my best run from my sig; all I have performance-wise is a Fujita intake. Imagine if I had ran on a 1/4 tank, nothing in the trunk, had headers, exhaust, and had lighter wheels!
with a 1/8 mile of 8.64 your 1/4 mile time will be in the 13.4X
Does anyone know what the stall limit is for the torque converter on the IS350? Since my IS is equipped with a very high-end LSD, I wonder if I can take advantage of brake torquing at a high RPM from a dig (without killing my torque converter) ?

custom hood sealed intake, PPE header, custom exhaust, mapecu leaned to 12.1~ + 4 degrees of timing, deburred and polish throttle body and lower intake runners. Passenger seat in, spare tire and junk out. 18.9x5 ruff wheels(heavy as hell) and 285 nittor 555r's which was overkill.
Consistently ran 13.4's at 104mph last year with no weight reduction. 1/4 gas, Joe-Z intake w/ F-sport air box, stock wheels. Added Tanabe exhaust and plan to do weight reductions and run at the same track as Caymandriver did- doubt I'll hit 12's but hopefully a lower et. Cecil County Dragway is known to be a fast track!
