hmm ..

i guess all l15b7 turbo engine of honda are single scroll.

[tech_wiz]

Nope. There you go. So practically speaking if PKDM XI RS are found out to be single scroll, then my assumption which I stated earlier would be correct.

Hmm ... interesting .. someone was also saying that xi rs has the 1.5 turbo 11th gen accord engine .. so lets see if that version has a twin scroll ... i hope that local rs also has twin sroll.

Globally that is true to an extent. Still 180hp/240Nm power numbers fall short of Accord 1.5 Turbo. But for PKDM market I’m not so sure. Atlas’s marketing department can’t be trusted.

Some feedback on the actual car itself.

-Trunk space I found out today that it isn’t really accommodating since the height is on the smaller side. More annoyingly, even if you do manage to fit the stuff, the sensor won’t let you do it. The trunk keeps on opening followed by a beep and then it needs to reset by removing everything but the dheet thing won’t close when full.

-The cvt is laggy and rubber band type elastic feel affect is there but since we’ll have to live with this technology till we can afford german cars with a Dct or a Zf, it’s much better calibrated than the 10th Gen. probably due to the higher torque. I seriously even prefer the 4 speed ect that altis offered over these cheap Cvts.

-The handling and road grip is definitely a notch above the competition (at least locally).

-Interior quality and plastics, fit/finish/feel are definitely much better than the 10th Gen.

-The biggest talking point i.e. the 127 bhp, well it is what it is and I honestly hate atlas for this fazul harkat but its not underpowered at all. Yes it becomes a little bit noisy when pushed but that’s more the cvt however for regular driving it’s not the 1.3 Gli level of underpowered that we experienced with the toyota 11th gen.

if you have the budget, definitely RS is the way to go but buying oriel doesn’t mean you’re not an enthusiast, it all comes down to affordability.

The map cannot be flashed directly

Thai is less than malaysian as well. On wheels pkdm and malaysian dyno results are same.

Nowhere in the world stock 11th is quicker than 10th .. be it SI or regular CVT. Furthermore, once tuned 11th is way superior in response.. due to some engine optimizations…

[fastian04]

Engine is same across the globe… turbo part number is different in x and x1z atlas didn’t do any magic at all with engine. We have base fuel less than 91 ron and adjustments make sense.. all turbos give optimal performance with hobc.. so that hardly matters but good since there is no knocking across Pakistan … kind of peace of mind

[fastian04]

Turbo part number is different as dealership was claiming warranty for one of the cars but m sure even atlas is not aware of it as specs say single scroll but its accord engine for sure

[fastian04]

Basically what happens is u take original map and make adjustments. Torque delivery is very different in both cars actually. U can be very close to stock RS even within safe limits

[fastian04]

Thai has 176 as well… figures are claimed right on average fuel we have. Dyno shows hell of difference on regular vs hobc even..

[fastian04]

A relative owns SI in US and he told me that he needs premium fuel to get proper output so it made me understand the Pakistan is not the only one.. the car will drive fine, wont knock but figures are very different in reality

[tech_wiz]

Single scroll is bad news. 10th gen X RS had MHI turbos, this one should have double scroll made by IHI. Only if Atlas could provide the clarification. Malaysian has 240Nm unlike ours which is still 220Nm as per Atlas. Hence my skepticism.

[fastian04]

Thai friends has already confirmed that its single scroll in asia but yes part number is different .

Something is still different as turbo lag was too much in X vs X1 and twin scroll
Plays part in this area

Plays part in this area but here is what it is

But actually its an improved design and is not twin scroll. Below articles explains in extreme detail about design changes by IHI vS MHI

Here are my observations for the 1st 10k kms

Stock factory boost peaks around 14.3 PSI when external temp is around 24c

Tuned 19 psi in X1 is around 0.5s quicker vs X at same boost.. X1 also had advantage of keeping 3 maps kist the way X( usdm) used to allow .. no vtec ones.. asian was different and could keep only single tune with eco button.

On rolling when hitting 3500+ rpms, X1 is well ahead of X but on start X is quicker in any case (tuned or stock) .. something to with IHI turbo here..

On 21.5 pSI 11 gains better than X could achieve and surprisingly on X1 when external temps are over 40c , my boost remained under 20 even when pushing 21.5 PSI.

On regular fuel max boost on stock map is same.
On 19 and 21.5 PSI, 95 ron (PSO) gives best performance and i was able to hit full boost figures.

In 200 plus run averaging lower end of 150kmph, cvt temps remained at 105c ( 124c is threshold) .. all in all, intercooler upgrade means u are going under 6 second got sure as boost will be easy 27 PSI.

Hmm .. and how would you rate its overall comfort and the low end torque if say compared to its competitors like 2.0 elantra .. does it still feel powerful enough to jolt you back in the seat when you floor it ? Many people praise elantra for its performance and compare it with 1.8 grande and civic but they dont realize that they are comparing 2.0 with 1.8 obv 2.0 will have little edge .. it would be fair if they compare 2.0 corolla or civic with 2.0 elantra.
