4B11 vs 4G63? | 1170HP & 53 PSI++ Of BOOST Worlds Fastest EVO X! [TECH TALK]

4G63 vs 4B11, best turbo back pressure ratio and is the biggest turbo you can fit the best? Let's find out!
Running 1170HP, 680 ft-lbs of torque and in excess of 53 PSI of boost, the English Racing Mitsubishi EVO X is pushing the boundaries and leading the pack to be the fastest Mitsubishi Evolution X in the world. Driver Myles Kerr discusses some of the challenges that come with pioneering a newer platform and where he sees the 4B11 being superior to the proven but now dated 4G63 power plant. Despite what a lot of people think, it does take more than just a healthy bank account to get this done 🤓
This Extreme Turbo System built EVO X runs Golden Eagle sleeves, stock stroke GRP Connecting Rods, a modified factory crank, GSC Power Division valvetrain and S3 cams, a Precision 7685 turbo and the MoTeC M150 with John Reed Racing modification brings it all together. The team had some huge drivetrain issues before getting the weight down and the car now runs a Graf h-pattern 5-speed dog box, Shep transfer case, Driveshaft Shop shaft and rear axles with a Mitsubishi 300GT rear diff. The power is currently a fixed 50:50 split and in the clutch department, an Exedy triple carbon clutch and Magnus Motorsports slipper system keep the launches consistent.
Andre and Myles also discuss why the biggest turbo isn’t the best, where there is still more weight removal to be done, the 4B11’s advantage of the 4G63 at low to medium power levels and the sweet spot for turbo back pressure when it comes to drag racing.
At the TX2K 2019 event, Myles and the EVO set a new record with an 8.167-second pass at 180.79 MPH so the team is on track and creeping closer and closer to that 7-second pass.

I've had 3 Evos: a 2008 X MR in the US, a 1997 IV here in a Japan, and now another 2007 X GSR w/TC-SST, also in Japan. I love the X as a street car. Yeah it's heavier than the 8/9 but it also has a better AWD system which makes it faster in the twisties. Using an Evo X for drag racing, is, IMO, like trying to stuff a square peg in a round hole and complaining it doesn't fit. The 4B11T is an awesome engine and under-utilized by Mitsubishi and the other companies in their conglomerate.

[@LatinoAD]

Myles preaching the truth 4g guys hate all you want I love the 4g but the 4b11 is great and hold/produce fully stock internal 500hp reliably vs a stock 4g63. Graf 5 spd dogbox ftw 💪

Interesting to see the 4b11 progress and how the 4g63 is still moving forward

[@dj4monie]

4G6x is still going to be around. As factory heads and blocks start to become harder to find, the aftermarket will step up. The tuner market in general is woefully behind the V8 market. That is mostly because these are entry level cars and most people as they get older move on, especially when they start having wives and children. 4B11 is a world engine, it is shared with the Caliber SRT-4 and Genesis Coupe. Minor differences in all but Exo X community has a hard time living with that very real fact and hate the other platforms especially the Caliber since it was more CUV than car.

[@LatinoAD]

@@dj4monie well they do make billet heads and blocks for the 4g63 so if you can't find factor heads or blocks oh well pay some more hello billet 😊.

[@josephandreuccetti8043]

Anthony Thomas V8s have nearly 60 years over turbo 4cyc cars Really the modern golden era of Japanese performance engines and cars of this nature is only 20-30 years old They have gone faster in a shorter amount of time vs all the years and head start the V8 has along with power and development Turbo era was the first of true power in the 4 cyc world. Again still very very young and new.

This 4G versus 4B argument over the years is getting old tbh if you ask me. It’s called the Evolution for a reason. What’s the point in calling it an evolution if it’s not gonna evolve? It always evolved from first evo to the 10. Changing the motor design meant evolving. In my eyes, it’s an upgrade.

[@hpa101]

Yes, but there is also the element of comparing a stock engine from the factory to one that has been modified, and what is available in the aftermarket for each option/the problems that need to be overcome etc etc etc - Taz.

[@XHikotheproX]

I wonder if the 4B11T will become the same thing the 4G63 is today in about 10-15 years. Great video

[@hpa101]

Yes I was pondering the same thing. So many different factors play a role in that right from the basics like availability through to the demand for aftermarket development. Time will tell - Taz.

[@dj4monie]

@@hpa101 Well in overall availability. The engine was seen in the Hyundai Genesis Coupe and Dodge Caliber SRT-4. But I believe the 1.8L and the 2.4 N/A (R/T) engines in the Caliber all use the same engine block and are both DOHC I believe. So with millions of Calibers on the road, there is a ready supply of engine blocks. The Caliber SRT-4 had variable valve timing on the intake only I believe, I don't know about the Genesis turbo engine. Another factory in development is the fact that both Diablosport and HP Tuners are available for the Caliber SRT-4. Only about 5,000 cars were built though and given the tiny community we're talking a handful of people are even interested in going over 500 hp. I've always wanted a Caliber SRT-4 after my Neon SRT-4 because I like creature comforts and the Caliber is a tech wonder compared to the very basic and bare bones Neon SRT-4. Most of the really fast FWD Hondas employ clutch slipper valve as well, however that memo hasn't made it out to the rest of the FWD drag racing community, it's an EGO thing...

[@rushking19]

@@dj4monie Hyundai helped design the 4b11 with Mitsubishi and Chrysler that's why the genesis coupe motor is similar but also it's a lot different

[@hpa101]

@Anthony Thomas: I was also referring to 4g63 availability too with that comment. As I mentioned, so many factors. We'll see =) @rushking19: I believe the 4g63 was in a number of Hyundais too, or at least some license built version.

[@eubo383]

Can some of this engineering be applied to the 4B11 derivatives like the G4KD engine to make reliable power or would it be better to just swap the G4KD for a 4B11 once off?

[@johnryan8985]

Such a cool video

[@CP110]

The reason he stopped bending rods is because when he cut down the rod journal (most likely honda diameter) it effectively lengthens the rod a bit improving rod ratio putting less stress on it.

[@Sup_Evox]

Can’t wait for domestic Vs import this year 🤟🏼

[@wdwickham]

[@spen2805]

These interviews are great! Thanks for providing such good content. Can you explain the less than 1:1 back pressure and how that works? Seems physically impossible to me.

[@dj4monie]

It's not, sizing your turbocharger correctly, along with cylinder head flow, exhaust flow and exhaust camshaft will all play a roll getting 1:1. It is not impossible but unlikely with the vast majority of home and even professional builders of 4 cylinder engines. It's hard to do in the V8 world... Just live with a little backpressure, everybody else does and still manage to go quicker and quicker.

[@ogswagkillapbeastmode694]

4b11 vs 4g63 reminds me alot of k series vs b series. k series is a better engine that flows alot more and is stronger from factory (possibly the only difference from iron 4g vs aluminum 4b) but we still see b series on top in the turbo world. love these tech talks

[@blu3flare25]

Another major diffrence is the valve train, 4B11 has shimbucket valves. Vs 4G63 hyralic lifter/rocker arm style. A huge improvement when it comes to high preformance engines.

[@ogswagkillapbeastmode694]

@@blu3flare25 tru that. k series got a vtc system to go with the traditional vtec which would modulate timing too for a smoother vtec changeover and power area under curve. i-vtec vs vtec but i still prefer old school

[@senior520]

Great car, but why is ACD being compared to a variable torque system like ATTESA? ACD cant actively bias power front to rear, it only controls difference in slip between them up to maximum available clamping force of the clutch plates. It's still a fixed 50:50 split mechanically.

[@kalashnikovcortez1380]

[@DkingE39]

This was a great video, the only thing I didn't understand was why did the bigger journal bearing bend the piston rod. Was it the reciprocating mass putting too much force in the ROD ? I remember back in the day it was the opposite. This probably the only big TQ evo X I have ever seen

[@Andrea_eTi]

Smaller rod journal, you can make a bigger rod on the Big end

[@DkingE39]

@@Andrea_eTi I kinda under stand that logic but shaving down a mm to get mm in stroke is going to prevent the rod from bending is where I don't understand.

this reminds me of k series vs b series, the k series flow better but the b series has that lower compression and you can turn up and turn up and turn up the boost

[@DavidNJ1]

Why would the flat tappet buckets of the 4B11 be better than the roller cam on rocker arm of a 4G63? Just looking at the GSC S3 specs, the roller cam has much more lift in a shorter duration, and the R2 has a greater major intensity and even more lift with even shorter duration. My V8 experience is that lifter diameter is important and roller cams blow flat-tappet cams, like the 4B11, away. Why would this be different here? Sidebar: don't F1 engines have rockers with a de facto roller cam, instead of a roller using a DLC-coated rounded contact on the rocker, directly over the valve?

[@ThePunkabahkau]

Rocker arm got ratio

[@kamperformance5281]

Isn't valve acceleration faster and more aggressive cam profiles be used with the Roller Rockers ?

[@jon3872]

I'm not sure if you have made a lesson on it, but can you do a lesson on using ECUflash, I'm still having issues on making definitions for my 2008 Mitsubishi Lancer. I'm able to make modifications to my maps, but I've been told my definitions are out dated some how

As a dealer/part of a dealership, what do you mean when you say you "oversee" the build of something like that?

[@Fopeano]

@@pyrhoe We are the rare dealer that is completely reasonable about modified cars because most of us that work there have them and are into that sort of thing. Overseeing that build means: My friend/co-worker who owns that car is not a mechanic but does his own work. Especially with a car like that, one needs to generally understand forces/clearances/stresses and mechanical interaction between parts to build something like that. I hangout and do my own thing when he's working on it, but watch/advise/teach as he works to make sure critical things don't get overlooked and are properly assembled and installed.
