LEXUS GS350 F Sport Dyno Test (With Full Bolt Ons)

Some of you guys had asked that when will I take my Lexus GS350 to the dyno jet to see the results after upgrading the performance mods?
And finally here it is!
I apologize for the high background noise which was difficult to hear me during this video.
#KeepFastAndLoud
Here’s the link of the first dyno run video in case you ask how much horsepower and torque it achieved when it was stock except with the K&N aluminium tube and filter.

I have a 2012 IS350 F-Sport. Here in Australia we get the 312 bhp engine. I am upgrading to the F-Sport intake and RR-Racing tune. They claim 10 - 15 hp increase, and the F-Sport intake may give 5 - 8. So I am hoping to get about 20 hp increase. The mid range torque is what you feel when you accelerate. HP makes you faster over the same distance ie 1/4 mile. At the moment mine runs 0-60 mph is 5.25 secs, and 0-100 km/h is 5.59 secs (VBOX and Dragy tested) My goal is to get into the high 4s to 60 mph. A sticky surface at the drag strip, cooler temps, the mods, may get me close. I will put it all on one of my channels. Other mods I can do like PPE headers, mid and tail pipes but these are crazy prices here. So Intake and tune will do.

Hey love the car. Where did you get the rear quad diffuser/ valance? Link please. Thanks

[@tij683]

What is the rear diffuser that you have?

[@donniecoe5495]

You gained like 50hp at the very top end though. Under the curve gains were crazy

[@BLacknesmonstaz]

Are you higher above sea level? Im thinking Oregon= hills-mountains maybe higher up maybe :) It's hard to get a good reading when that's part of the factor. But your car looks dope.

[@jaz1104]

with RR racing tune i got max 284 wheels with drop in intake + stock exhaust...perhaps in the future i'll go for axle back....full PPE headers + catback too costly here for another 10whp gain..Happy enough =)

What kind of rear diffuser do you have?

[@whitewolfstudios4727]

Not too bad for boltons, I live in Korea and there's a company that says they can provide an additional 70 bhp just through a remap, not sure if I believe them but they are quite reputable. I might get boltons too...

[@nashh123]

What springs are you running

[@VR408]

Nice! Kind of disappointed you didn’t clear 300whp. Keep up the good work bud

[@StarK12trd]

Thanks, I know it kinda sucked it didn’t reach 300 as I was hoping for but if watched the ending part of the video I mentioned I got a tip from the fb comment said that dyno results from different locations varies so not created equal. The results can show 285-315rwhp.

[@VR408]

@@StarK12trd Yea, that's true. As long as you're having fun with your car. That's all that matters. Did you paint your Lexon diffuser black or did you receive it that way?

[@StarK12trd]

@@VR408 actually the Aimgain diffuser came white fiberglass so I had someone to paint it.

[@VR408]

@@StarK12trd Didn’t realize it was an Aimgain. Did you have to modify it to get it to fit with your quad tip exhaust?

[@keithcha7372]

how many test pipes you need????

[@jfin711]

Were they sure to press the gas pedal past the throttle switch? It feels like full throttle but press harder and the gas pedal will move more.

[@StarK12trd]

Hmm beats me if they need to press harder or if they’re aware or not to press harder. Yeah while in full throttle you’ll have press down the pedal harder so it can floor it all the way.

Did you happen to get TRAC OFF and check engine light with lean code after intake install?

[@ovejeromd]

check your o2 sensors

[@zacharymedeiros2713]

When you did your exhaust did you have to swap the defuser?

[@StarK12trd]

With that exhaust, yes. The OE diffuser will not fit, unless if there other performance exhaust systems to fit that OE diffuser.

[@shazmaster]

One thing you should not discount either is the weight you lost after the mods. Maybe get some lighter wheels and rotors, those would definitely make a difference as well.

[@SanicGottaGoFast]

The power gained under the curve is literally everywhere thats what you want. Those are the gains you notice. Don't pay attention to peak horsepower that much.

[@730F-Sport]

Where did you get the diffuser?

[@StarK12trd]

It’s the aimgain exe type 2 diffuser. From topendmotorsports.com

[@kgisabeast]

Hi, I have a couple questions. What modifications have you done to get here? Do you plan on supercharging your car? Sorry, I have a 2016 GS and am curious where to go next with mods LOL

[@StarK12trd]

Performance wise is the full bolt ons including a tune, headers, catback exhaust, and intake. I was considering to get it supercharged but I decided sticking with naturally aspirated.

You need a better editor dude the Background music is way too loud while you're doing your videos. And was it really worth all that money for 20 more horsepower

[@PResmejor]

Your car is gorgeous and sounds but i wouldn't call it FBO , you still need a bigger TB, upgrade your plenum and manifold(either by getting a custom one made it getting it ported) and upgrade spark plugs and coilspacks to consider it FBO. Your car can be making around 330-340whp NA. But you got yourself a new subscriber and i would love to see more videos of this beast ! 👌🏽😈

[@StarK12trd]

That’s an awesome idea. So where do you suppose I find the upgraded manifold and plenum for the 2GR in particular?

[@PResmejor]

@@StarK12trd i was speaking to a guy on the club Lexus forum who made his own custom upgraded manifold that he was testing out to see if he could sell it to others so they can benefit from it as well. The manifold is also set To be able to run the tundra TB (76mm) as oppose to our stock TB which is 70mm. If not you can always go to your local machine shop and get your manifold ported, lower manifold can be opened up 5mm bigger and the plenum(upper manifold) can be opened up to 74mm .
