Hello everyone. I could not find any real Dragy GPS numbers on here. So I'll be helping out the community for once, lol New member here.

Now my IS is a 2006 RWD with 161,000 on the odometer. Fresh oil change, 93 Shell gas with an AFE drop in Pro Dry S filter. Let me know what you guys think. Also This was on Michelin X-Ice winter Tires 245/40/18

5.41 best 0-60 so far and 13.87 best 1/4 mile. Keep in mind my 2013 BMW X3 35i did the real quarter at the track in 13.75 sec @ 100mph, so this lexus is slow as hell.

 

These are my times with my 2006 is350. I did have Michelin pilot super sports but they were pretty worn out and I had to easy into the throttle because to limit the wheelspin. I also have the RR Racing tune has my only performance upgrade. I returned the draggy after 2 days of using it. Because i quickly realized that I was just burning tires the majority of the time and not putting up that good numbers. So in order to not be in need of new tires quicker than expected I returned it. And I still ended up needing new tires within 2 months lol now with my new Michelins I could probably put up a better times than I did but I rather not try it

 

Decent numbers but not good by any means. The tires really held you back of course. Our numbers are not far off whatsoever and we both had the same 60ft on the 1/4. Plus my engine has 161k, lol. How many miles on your IS? I Really want the RR tune. Do you recommend it? I'm more inclined to try the OV tune, it looks more aggressive. I kind of want to blow my engine so I can drop a 2jZ in there, but for now. I want to do FBO plius tune and I want an E30 map for E85. Let me know your thoughts

 

No electronically calculated numbers here, just actual 1/8th mile times to help compare :

Of course it helps it is a prep'd surface and I had summer tires.

 

I have 130k miles on mine. I really loved the tune when i first got it especially since I could hit 60mph in 2nd gear which does help with that 0-60 time since stock you have to go into 3rd. now after a few months of having it i got used to it and its not as exciting as it used to but i still like it. i can still take down other is350s which is nice to do lol I haven’t really hear much from the OV tune while I heard a lot of positive stuff about RR racing which is why I trusted RR racing. I do recommend it

 

I seen that thread before. pretty impressive to do a 8.6. when i was timing myself with the draggy i wasn’t brake-gas launching. i wonder if I did that with some new tires if i could of gotten something similar to that like a 8.7-8.8

 

Thank you. I appreciate the feedback for comparisons. It's crazy I trapped higher than you on my 1/4 slip at the 1/8 mile time. How many miles on engine on your run? With 161k miles on mine. I'm fairly impressed. I hope more members post their stock and tuned runs.

 

LOL yes the pursuit of speed is never ending. Boredom sets in quick. I would also assume like 4-6 months down the line. I come from 6 BMW, 3 of them pretty fast. I just want to be able to run at least 12.5 @ 114mph. That is what my best time was at ATCO Dragway with my 335GT tuned (no flash, just piggy) and downpipe only. Your trust in RR is reassuring to me. to say the least. I really appreciate the feedback bro!!

 

I can also vouch for the RR Racing tune being a fantastic upgrade and having solid reliability. I regularly take my IS350 to the race track and the tune is essential as it lets you stay in the lower gears for a longer period of time.

I have a neighbor who recently offered to let me borrow his GPS unit in order to obtain a 1/4 mile time using the draggy app. With you starting this thread, I think I'll have to take him up on that offer.

Regarding your 0-60 time, you can definitely do better with a fresh set of tires (particularly UHP summer tires). I don't have a draggy recorded 0-60 time but this is what I managed to pull during a warm summer night (I'm overdue with recording a pull during the cooler winter timeframe).

 

I don't have any 0-60 or 1/4 mile times, but I do have many logged 40-60 runs. Your time above has a ~2.2 second split from 40 to 60 with what's pretty much a stock IS350. If you want something to compare against, my IS350 is pretty much FBO + tune and in favorable conditions I'll get a 40-60 time between 1.5-1.7 seconds, with a rare 1.4s.

I still have a couple things I'm considering to increase hp, but this is probably as fast as these cars are getting within reasonable spending. I think a 12.5 might be doable, but I don't think 114mph na is happening.

 

damn a 1.4 40-60. thats 33% quicker than me at 2.1. i wonder whats your 0-60 and 1/4 times. i dont think a mid 12 sec 1/4 mile is possible with our cars if NA. i think a mid-high 12 sec is probably the best without forced induction, like a 12.7-12.8. i hope that i could my car at 300whp while keeping it NA but seeing redspencer's is350 getting 293whp i dont think its going to happen

 

try it out... im really interested what times our cars can do while keeping it NA. Because a 0-60 of 4.4 is pretty crazy. thats pretty close to a stock isf which is insane if you think about it. a stock ISF has around 70-80 more whp than you and you arent that far behind in a 0-60 race

 

Keep in mind that for the most part 0-60 times are more about traction than power. You can only accelerate with the power you can put down without spinning.

​​I do think mid 12s are doable, I am probably high 12s as is if I get traction sorted out. The difference in our 40-60 would damn near put you in the 12s, I wouldn't be too surprised if there were another few tenths difference between us from 60-100mph.

 

I believe a FBO+Tune 2IS350 breaking 300rwhp is very possible. Some dynos are more conservative or generous than others with the whp which is why dyno numbers are best used for comparing different setups on the same dyno.

 

I remember seeing a video of a stock isf racing a stock is350. The gearing on the is350 is much shorter and the is350 was actually ahead at the 1/8 mile mark but lost in the 1/4 mile mark. I was debating to switch over to a isf as my daily driver but decided against it because of that. With similar performance under 60mph, better gas mileage and better looks (IMO! ), I stayed with the is350 (now at 191k miles) and added some upgrades (also stayed with larger MP4S's).
