Great comparison vid. Having a direct comparison between the two cars with both a drag and roll race brings to light what each car can do. Once the ISF has a FBO setup (to include headers), it should be a closer race.
Kinda hard to compare a NA (anything) engine that’s basically stock to a modified and boosted engine Definitely get why the comparison was done and I love the video, but a FBO IsF vs this SC350 would be more comparable and realistic as far as I’m concerned
Making the is350 community proud 🥲 ,would love to see a rematch if the ISF gets headers . And I would probably prefer the ISF over the is350 because I already have an is350 and experienced it lol
Very very cool run guys! I personally prefer the IS F's sound overall, but the exhaust changes you've implemented are leaps and bounds better than the previous mod.
Great comparison! Really wish you guys would have done another 40 roll where the ISF started in the right gear though. You could hear him go from a really high gear in that race and the car went no where when you both left lol. The 350 is running great though!
Really enjoyed this, I use dragy all the time. I managed a 4.42 in my 08 ISF (catback H&S) to 60 and a 4.53 to 60 in my MY11 (secondary deletes H&S), both verified. Also in the 1/4 in my 08 12.55 @ 113.31 and my best in my 11 so far is 12.72 @ 107.56. Manual/sport/tcs off/vsc off was my best method. I think the stock suspension in my 08 helped my launch as it’s way stiffer than the MY11. I’ll say this mate, that 350 is quick in a roll! Great video!
Much respect for the disclaimers. Had they not been there and viewers reminded of, there would be a lot of conclusions about waste of time, money and cars being slow. Well done! I have a 2008 GS 350 and a 2014 IS 350. I definitely plan to supercharge one of them. Still not sure which. I love them both and have had them for a few years.
@@stephenrand5033 I love the comfort of the GS more as a daily. However, the IS 350 is definitely faster. With same motor and power, the IS 350 in 2014-2020 shape is faster than every generation of GS 350 and noticeably so. The older IS 350, however, the 2006 to 2013 models, are only quicker than both generations of GS 350 through the quarter mile and to 60. After about 80mph it starts falling flat and the GS350 of any generation will pass it on the highway. So overall, the 2014-2020 IS 350 as a daily is the fastest of them all. I have lined up with the 2006 IS 350 (actually owned one) on the highway in the 2014 and I am much quicker. From light to light he would walk me though.
@@nallis01 Interesting.. I’ve driven a 2021 is350 and idk why but it didn’t feel as if it was faster then my 14 gs350 maybe it’s just because I’m used to the gs more I definitely like the look of the is350 more but I chose the gs350 over it because of the size and comfort. I really wish I could get a GSF but there so expensive
@@stephenrand5033 you sir are CORRECT! That is why I specifically said the 2014-2020 shape. The 2021+ is a slouch. It only looks pretty. Same motor s the previous gen but definitely slower. Quarter mile on them are like 14.4-14.6 seconds. I saw one at the local track do a few passes. On the flip side, your GS does similar or quicker times. Every generation of IS 350 gets slower and slower.
@@nallis01 yeah it’s kinda disappointing. When I first got to drive it I was excited especially from the looks but then I was disappointed after the performance. It handles decent but the power isn’t there and yeah I’ve taken my gs to the track before and my best quarter mile was 14.2 at 100 I believe but I do have the awd model I kinda wish I got a 2015 is350 sometimes. I wish that for 2021 for the is they gave it a little more power. Even 330-345 would make up for the added weight
Awesome job on the video. Awesome job on both cars. And a fantastic explanation of both of your guys thinking, all while respecting your surroundings. Thank you🙏 Southern PA ✅️
Awesome comparison. Even though ISF wasn’t FBO still expected it to pull the 350 right at the end on rolls and digs. Crazy how the SC changed the car dramatically. Makes me want to SC my 250 haha.
The below is my personal tests on the same location and similar conditions. No launch control and traction control was on. 2017 GSF (empty gas tank): 4.93s 2018 M4 Competition (3/4 gas tank): 5.01s 2019 Q60 300hp (3/4 gas tank): 5.25s But, I do believe GSF and M4 are obviously faster after 60. (Of course)
Man l have been watching your video from you buy the first is 350 honestly u are doing a great job bro and most of all you did all the yourself that is very important l really enjoyed the passion and love you have for cars keeping these impressive video coming along bro love all the generations of lexus
Actually it is opposite, Auto shift are mostly better for acceleration. At least that is the case on Lexus and I am speaking from experience IS250>IS250AWD>IS250 F-Sport>IS-F>RC200t>RC-F. As much as you would like to computers are better at knowing when to shift than humans, the only downside is that if you expect kickdown, computer sometimes may misunderstand your intentions and that could delay things, but for simple 1/4 run auto gearbox on Lexus left to shift by itself will be faster than manual shifts every time.
@@ing8404 No it doesn't. Maybe on some cars, but certainly not on Lexus. First thing you need to understand - you can't shift manually in Lexus (except of LF-A), the paddles are for gear ranges. If you just have your foot planted to the floor they will change gears perfectly every single time. In practice you can downshift with paddles by limiting to say 4th or 3rd gear, so car is forced to downshift if it was in say 6th. But you can't upshift on demand, when you press paddle it does not upshift, you just tells gearbox that now it can as well use say 5th gear, but car will continue pulling in 4th and only actually upshift itself when it wants to. However, if you increase the range too late, after the perfect time for shifting, then you may bounce off the rev limiter as he did several times. This is because there is time delay for range change i.e. gearbox was limited to 4th gear, there was time to shift which takes ~100ms, so gearbox predicts that you will need to be in 5th in 100ms and would start gear change 100ms early for perfect shift, however up until that point you had range limited to 4 gears and only clicked the paddle to increase the range 20ms late + it took another 120ms for gearbox to increase the range, by that time car reached the rev limiter and bounced off and only 140ms later it realises that it is now allowed to shift and does it in another say 200ms. So instead of letting car do the change in 100ms, by trying to do it manually you would waste 340ms. And this is not only gearbox, it is as well ECM that manages all aspects of acceleration and when you over-rev the car it has to adjust to be able to upshift. When leaving car in auto, it not only shifts gears, but it as well controls VSC/TC/Throttle for rev matching, injection, valve timing and etc. to get absolutely the best gear shift possible. In short by trying to change gears manually on Lexus you are just interfering with system and preventing it from working optimally. A960E, A760E and AA80E are simple torque converter automatics, they are not DCTs and there is no point upshifting on there gearboxes. Downshifting for overtaking sometimes makes sense, but as soon as your foot is down it is best to push it back into D. There are manual conversions to A760E (so the gearbox in IS350) and it then basically works like you would expect paddle shifters to work, it actually shifts slower (say 200ms instead of 100ms), but that is sometimes acceptable, usually in turbocharged applications where top HP/Torque isn't at the top of rev range and shifting at say 4800RPM is preferable. But on NA or blower it is best to leave it to gearbox to do it automatically.
Been waiting on this one , great video Marty , what I would be curious to know is how reliable the 350 is with the supercharger kit on it and how it holds up in the long term , that could also be a deciding factor for someone looking into the IS platform.
It makes sense cause boosted 350 makes 500 at crank and 400ish and isf makes 400ish at crank. People don't want to believe a 350 can beat an isf but the numbers are right there
Marty this is a good vid I own a 2011 ISF, you have the ISF NOW and i know which one i would have. I have driven a few 350,s and there is no comparison as far as a complete car. have a look at Misha Charoudin, just released vid on the ISF around the Nuremburg ring track in Germany that tells you how good the ISF is cheers from OZ. PS I hope you read this.
I'd love to see you buy another intake manifold and plenum, port and polish them, get another tuning session with Rafi, and see what the whp increase is. I'd be willing to bet it's a non-trivial increase.
I would love to see how it compares to a properly running ISF, no offense to PMM. Before anyone gets butthurt, I completely understand how DA can affect times, but at 800ft you should still be close to 12s in an F.
These aren’t real drag times with 2 people in the car and going uphill, but we can see my car is .5 seconds faster. So on a drag strip, I’d probably run 12s while the ISF would be 12.5 in its current form
@@sircefiro Yes that older video was with my brothers ISF. They are both 08s, my brother has more mileage. I’d say they run about the same having driven them both
Doesn’t seem like you’re doing a 2 footed launch. If you’re not that’s how they get the times for 0-60. Left foot brake rev up to 2000 rpm and release brake . Both nice cars and great video
Interesting! I thought the F woulda been closer on those Highway pulls. It seemed the 350 was in 2nd and the F pulled in 3rd on one of those rolls. Either way love the video brotha
Impressive! I actually also own a 09 ISF and a 2011 USB is350 Fsport like yours. However, the ISF would kill you at a racetrack -- not a drag strip. It's got better cooling and it's designed for reliability. Everything is beefed up. The 350 would probably bake the brakes, transmission, or something would blow up.
Nice! Maybe, I’m not sure my setup is designed for long term track days (lots of heat) and I’m only running upgraded, fluid, stainless brake lines, ceramic pads and better rotors, but still stock calipers. The ISFs suffer from heat issues as well, as I’ve filmed a few at the track. It’s just a lot of power in a small chassis.
@@shiftautomotive854 I actually like my is350 just as much if not a tad bit more than my ISF. If I had to sell one, it would be the F. Shocking, I know.
Interesting video. Would love to see a dyno test on both cars, that would show the difference. Your 350 is very strong. You should run it on a nice prepped drag strip. It may be surprising. As for that ISF. It seems pretty dull. Mine was a dog until I replaced the MAF sensor and picked up 4/10 over the 1/4. Also manual shift sport mode is quicker every time than sport mode in drive. I hope to see a rematch. That 350 could be knocking on the door of a 11 second time.
Mine dynoed at 429whp last fall, while I’m not sure on this ISF but with his mods should be around 390whp. It’s very strong with the fresh transmission lol. Would be fun to see what it can do at the strip for sure. His ISF feels like many others I’ve driven. Even in manual mode and sport mode it’s quick but the boost on my 350 pulls harder. The ISF needs headers to make the race interesting
This is a great video compare. Dollar for dollar makes more sense for the 350 to be modded up if yr good with having a touch better than ISF speed. Which is no joke. We all know that the F with similar mods would be a beast but pound for pound the IS350 is gonna be way better on gas in normal driving, plus the engine fits under the hood nicely if u have 2 work on the car (which you will). Unlike the ISF where the V8 is shoe-horned into the F. I love the F cuz that V8 sound amazing…where the V6 sounds kinda ehh. But all in all IS350 will save you dough.
in my country the is350 is a standard car here, everybody has one and they are very cheap (5-8k $) and you can find an isf for 15-17k here you see them everywhere
With just headers and a 50 shot the 350 would be toast things will get even nastier if the ISF gets the RR Racing Supercharger it would be game over for a lot of cars
In the market for a Lexus 2006-2012 used. Need to know what years to avoid and what to look for. Just need a reliable vehicle nothing special. I do like the backup cam and would like AWD
I have a 2012 ISF and you make me rather have a S/C IS350. Not only because of the performance but that supercharged sound is so hot, can’t lie though that V8 grunt is unmatched.
Change of heart: Idk man all that work n added bs , points of failure,, etc, just to have the isf add some headers n true dual exhaust then smoke the is350…just get the v8 n super charge that
@@anthonyduckworth1918 A FI IS350 should definitely be faster than and FBO RC350, they have the same power train/drive line. The RC is just 200ish lbs heavier
I know there are some factors contributing to not the Quickest of times on these runs but they seem a bit slow...For example, My stock 06 is350 with 145,000 miles runs an 8.8 second 1/8th mile ALLDAY at our local track 🤷🏻♂️ just has Fsport intake and the 1st gen HKS Fsport exhaust Lexus offered in 2006 before the "official" f sport exhaust was released.
Nice! I had that exhaust on my old 2007 IS350. Got a 13.6 in the 1/4 with that car. I got a 12.4 with the supercharged car when I was a little heavier. The real world numbers on inclines are just never as good
@@MartyMotoring Nice! It is a good exhaust. Idk why they changed it up to the inferior "F sport exhaust" imo it sounds better. Not as raspy and no drone at all. Yeah, when you supercharged it that thing was scootin for sure. Was sad to see it go. Of course it is hard to top an isf because well isf haha. They are sick AF no doubt so can't even be mad haha. I've wanted to SC mine but it is pretty spendy 😑 may just put her on a small shot of spray. I know a few guys have done it and haven't really had any issues it seems like. There just aren't many of them haha.
very cool is350, but I'd still much rather have the ISF, perfect daily, great v8 power still stock enough where its going to have that lexus reliability, and like mentioned a lot cheaper then an IS350 + S/C. And I'll bet the n/a V8 does gets slightly better MPG.
Thanks! I sold the SC IS350 and got an ISF actually now and while it’s “slower”, the V8 and trans are great. Gets around the same MPG. It’s a great daily! I got a great deal on mine so it did end up being a little cheaper than the IS350 in my case.
Yup that’d be cool just double the price, $25k+ for an ISF and about $12k in headers and supercharger kit, not including install. Awesome if you have the money, lots of power
you think if i supercharged the 2grfe in my camry that it would be just as fast? and i personally like the 6speed more than the 8 speed i think the 8speed is geared slow
Old vid but did this car get sold to somebody in michigan? Someone is selling one same exact car. Same performance parts/supercharger, same color, same brake caliper color etc
1 day I will get the RR supercharger too.. 😄😄 How much is the supercharger with labor? Including the new trans? Do you recommend all is350’s to change their trans before a supercharger?
I am not sure what they charge for labor since I did it myself, but the kit is just shy of $7000. Most people shouldn’t have to replace their transmission, but mine was bad
