Alex’s tuning skills are second to none. He has tuned two different engines and platforms for me (Fiesta ST with “big turbo” plus my current stage 2 VA WRX) and my WRX has been running FLAWLESSLY for 86k miles post Alex’s 93 octane tune. I sold the Fiesta ST but it was running great too as long as I owned it. I won’t hesitate to work with Alex on my next car, and who knows it could be a GR Corolla?
@@stratifiedauto Sad update, and my 2019 WRX was destroyed by a tree that fell during the recent May 16 windstorm in Houston, TX. I am strongly leaning toward another new WRX. I deleted Facebook messenger (how we communicated in the past) and I will be reaching out via email for your thoughts on the FA24DIT and what you my recommend for a “basic” tuning path. I’m thinking very basic with TMIC, intake, CBE, and 93 octane Stratified pro-tune. “Conservative” and tuned for reliability above all out performance since I want to maximize longevity. Thanks in advance and I look forward to working with you again.
Compound turbo any small liter and just let the pump dump fuel and you’ll be surprised what compressed air and the correct amount of fuel for said air can do
that's just crazy almost 65 horsepower with e30 mix over premium, that's just bonkers. I would love to get a tune like that for my Gr but also able to tune it back to stock when ever. thats super cool. I see that car has had a lot of modifications would love to see what the numbers would be with the stock air box would really be.
@@stratifiedautoMy reasoning for e85 is just so I don't have to play with the mixing to make e30 or e50. Thank you for taking the time to reply to my question.
No, not even close. Probably not even e30. And at those power levels and RPM you also start getting valve float, so valve work and probably head studs are required.
@@CSHracernot really... depends entirely on the springs... the vw 1.8t only needs exhaust valves past 400chp because they'll burn up, but you don't need springs and retainers until you've passed like 500chp.
I haven't experienced valve float during the testing on this car - I have experienced it on others and you start to see misfires. Valve float however is a function of RPM and backpressure. Keep redline reasonable and be aware of boost levels. However boost is not the only way to make power. The gains from E30 are made without much increase in boost or back pressure. A lot of it is from the increase in efficiency from timing and fueling changes.
Im really interested in the back pressure situation with this car. Toyota in their marketing explained that the "unique" exhaust setup of the GR Corolla is for the backpressure issues they faced when pushing the 1.6 -- I am currently looking at almost straight piping mine. Could you expand more on that in relation to valve float? @@stratifiedauto
Man that engine bay looks like total spaghetti monster crapola. Sure miss the days of a clean b series honda engine bay. At least the type r kinda looks ok for modern times
I'm confused why you believe the boost gauge fluctuating with the gas pedal / throttle body is in your mind the hallmark of a good tune. It's going to fluctuate whether the tune is good or not. I would be much more concerned about the air to fuel ratio and the kr than anything else. But hey, the visual makes for a nice video ;)
What I was showing there which is hard to capture on camera is how boost responds to different levels of throttle input. It should be responsive and not oscillate.
Folks in Australia called Powertune Australia made 770hp on the gr yaris with just cams and valvesprings, but they did use some nitros. Other than that, the engine was stock bottom end... that's crazy. They live streamed the tuning process, too, and did many pulls. They said they will post more about it soon on ig and bring it to the 1/4mile
@@stratifiedautoThe GR Yaris was fitted with an upgraded head gasket, along with uprated head studs. Elsewhere, the intercooler was swapped out for an aftermarket version from Plazmaman, while the three-cylinder benefits from a Garrett G30-770 turbo. Powertune Australia has also fitted a turbo exhaust manifold, intercooler piping, and a dump pipe from Golebys Parts. A MoTec Yaris Plug-in ECU also forms part of the package. 2,200cc Secondary Injectors from Bosch replace the stock items. The Yaris also receives an Elixr Brushless fuel pump and a cat-back Akrapovic exhaust system. But that's not all. Even the gearbox has been replaced with a six-speed sequential transmission from X-Shift and mated to an ATS Triple Carbon clutch. Interestingly, Powertune Australia has decided to retain the stock rods, crank, and pistons. "We have pulled numerous engines down, and after doing a lot of comparisons and measurements, we believed we could make our target power with the stock items," said a company
@@stratifiedauto Your honestly not even stressing the motor at that level. I was not saying go to 500whp... those are the people really pushing the platform but 450whp would be fine. That was also 500hp on the older one. Toyota has made this platform stronger since then because their CEO races the car and breaks it with the engineers watching and your going to quickly fix and improve your CEOs car when it breaks.
@@UnstoppableMileage That doesn't fix it. People have tried several things, that does help, but with agressive tracking, you need more than some heat tape. That said, the number of people pushing the car hard enough to cause the diff to over heat is very small and if they are pushing it that hard, they will likely be OK dealing with the over heating.
Being in this industry long enough and having run setup and tuned pretty much every vehicle in this category I can tell you that each has unique characteristics that the owners enjoy. We help make them all better.
VW is junk. Former mk6r owner, and plus a bunch of different generation gtis. Why don't you light up a manual r, versus this car? Mods for mod, the GRC beats the F out of it
Yeah and when it breaks and the parts cost you 3 times as much on the vw as the toyota cost.... Trust me i had a golf and when the engine blew i was shocked how much it cost to fix. Might as well buy a entirely new car, which is what i did. Toyotas have always been cheaper to work on.
"At least 5kph over the speed limit" best line of the entire video. :) I'm going to request something. Could we also get the torque curve before and after the tune? And, how about the tune with the factory intake?
I think the GR corolla is supposed to be dynoed in front wheel drive. The all wheel drive system regulates power. The car will shut the rear wheels off anytime with the Ebrake on. In dyno mode, rear drive shaft our and ebrake on for consistency. Just what I have read in my research.
We did the pedal dance. We also tried it in and mode. Not much of a difference to tell you the truth. At higher speeds with no slip it will not engage the clutch packs much or it won’t be stable. Similar to focus RS.
Keep in mind this car had an intake on it already. The hp falls in line with that we see from modern turbo cars. The little motor is a strong performer!
those advans look incredible on this corolla. I spotted a GRC for the first time yesterday, looked like a corolla hatchback until I heard the blow off valve.
