Very rarely I seen a production car 4cyl utilizing a water-to-air intercooler; note the M235i 3.0 I6 twin turbo & RS3 2.5 I5 turbo still retains a air-to-air unit. Goes to show the crazy steps AMG had to take to make this level of power in a 2.0 liter motor.
Ronald van de Kant The 3S-GTE was born & bred to be a racing unit. The Celica GT4 used it not because it was necessary but for homologation purposes to be used in racing. Heck, even the hottest GT4 ST205 had less power than the comparable Lancer Evo & Impreza STI! This AMG unit is never destined for racetracks, but for road use.
+Trades46 very true, plenty of these on the racetrack tho. Was just mentioning it to illustrate water to air intercoolers have been around for a very long time, and are not a revolutionary new thing on production cars and definitely not in the aftermarket. It was bound to happen in today's small displacement turbo era.
Trades46 they used a water to air intercooler to keep the boost pipes short which improves response and allows for efficient heat exchange without heat soaking into the intake air.
Short air ducts are very important for quick response and power. I pity the guy that has to service that motor. But then again you have to consider their legendary quality and durability.
At these compression ratios it is very tricky whether the fuel-air mixture will not detonate. Also these high combustion and exhaust valve temperatures it is very likely to burn the valves or wear off easily the turbocharger bearings resulting in much lower horsepower A Marine engineer
@@E9X330 I mean lmao if it comes like that from the manufacture and whoever put it together at MB... you can’t really say anything about that lol. A cla 45 is an AMG.
Direct injection alone takes care of most if not all of these problems. Hyundai has a 2.0 turbo with direct injection and a high compression ratio, for a turbo, and quite a bit of horsepower. It will run happily on 87 octane. Not a Marine Engineer
@@danparaschivoiu8620 been thrashing it going good change oil every 5000 km shame I can't change gearbox oil myself though. would like to give it a go. nothing step by step on utube.
Here's what I know, ecu remaps are obviously better however they are not truly invisible, no mapper will guarantee that, having the ecu mapped means having it removed and this then become a ballache if you don't want to risk the dealer having any chance of seeing it... Piggy back boxs also aren't fool proof but at least can be removed at the owners pleasure. A guy in Poland or that area bought one from a smaller outfit and in turn the dealer spotted it and now his warranty is void on drivetrain, it's not all void just turbo drivetrain etc...I'm with you on some dealers allow it, but would you gamble that with a 45k car I wouldn't. RENNtech have just release there own ecu remap but that goes to 465 bhp.i personally wouldn't touch ecu remaps unless I'm looking at 450 plus, why bother when rebellion and RENNtech the leaders have boxes that are easily removed.... Convince me lol
I like it but those lines on top (AC?) have too much flex. also, that high power output/delivery is only if all sensor parameters are within specification. otherwise, you aren't going to get what you paid for. I'd like to see the performance after 100k of duty.
Да нет там никакой пожизненной гарантии, такие моторы делать уже не выгодно. Кстати, в моторном отсеке настолько высока температура(после обычной езды), что открывая капот я обжег себе пальцы. Все что вокруг движка обмотано фольгой. Нелегко и тесно ему там...
Renntech,rebellion and brabus all use the standard turbo and get 400bhp, the first two are aftermarket and do void the warranty, however brabus keeps your warranty if done within 300km from purchase, to increases past 400 a new turbo is recommended and then you can easily get 435 plus.... How strong is it, well so far a lot have gone 400 and had no issues at all, take note Subaru with ya crap ringlands LOL, 7 weeks and counting for mine, longest 6 months of my life LOL
Cartel893 Your probably right, MSL performance in Birmingham UK are Weistecs UK disti, they have fit a downpipe and tuning box and the Car generates 435 BHP. Also the GLA 45 they bought Brand new after only 200 miles, generated 395 BHP STOCK, yes STOCK nothing done. It shows that's the A45/GLA45 although pitched at 360 are that and more, generally generating 365 to 390 Stock....
need to be careful doing the ECU, when its serviced they can spot it, you really don't want a 15k engine void of warranty. As long as you agree to the age old risk with Warranty im all for proper ECU remaps, just twitchy bum if you have 1
I would also have laughed at the diesel question...had I not driven an Audi SQ5 twin turbo 3L v6 diesel with over 650Nm or torque (from memory)...It even sounds fantastic! Anyway, impressive small capacity engine...sure you can tune an engine, but i'd like to see it come with the same warrante... Now please please please stop serving us up automatic 'sports cars'...give me a manual any day...I want to be involved.
2016 version of this engine has 381 HP and 475 NM. Great but i would like if they take it to the magic 400 HP. I mean WV has it Golf R420 whit a 420 HP 2 liter engine on the way and Volvo has there triple boost 450 HP 2 liter engine but it still a prototype engine, but hope they will release it for production. So Mercedes come in the game and all ready now show how it is done and beat Volvo and WV ass whit a 500 HP 2 liter egine i dare you guys. maybe whit twin turbo and a supercharger.
500HP on a 2.0L? I don't think that's necessary yet and would likely affect response times. Adding a supercharger means more weight and friction, that would throw the cars balance off and increase emmissions with worse fuel mileage. Its fine how it is for now, no need to chase for numbers and ruin refinement
Whit the modern teknologi there in engines today, i dont think it would ruin rifinement. The supercharger is also thats why they shut ad it. More boost at low RPM and that will give higher pressurer on the exshaust to spool op turbo´s faster or they cut use one those ned elektric supercharger manufactors are beginning to use and even it that is not enoufh to get rid of turbolag they cut use a hybrid setup where the electric motor can boost and help the petrol engine until the turbo´s ae spooled up. There are solutions to that problem bigger turbo can cause like turbolag. I am a huge fan of small power engines. Because that is low weight and lots of power. A 500 HP v8 would deffently be much heavy than a small 2L 4 banger. Only downside i se with a small engine compare to a big lump of a v8 is the engine sound, but even can be deal with by using a croosplane crankshaft insted of a flatplane crank. The sound would much different and much better.
I doubt this engine will get much more hp with such a small twinscroll turbo at 26psi stock. I don't think 400hp will come easily or reliably. But if u could get a nice 400-415 hp out of it on stock turbo it'd probably be able to run 4 sec flat 0-60mph. 450 hp probably get it to 60 in 3.5 sec.
German cars are not tuner cars, they don`t like when people tune their cars, and they make it hard, while most people tune their sti`s or evo`s to above 400 hp, this car will be a stock car for people who don`t like tuning the car.
Lucas Schaaf I got 100 whp from my evo x with boltons and tune, no turbo upgrade, no cams, no intake manifold no exhaust headers, and it is reliable for 3 years now only with oil change, and most people can confirm this, now no german car I know of can do this without major modifications.
I have a friend, who owns an Audi A4 1.8T from 2002, he had an ECU remap and got 70 bhp out of it. A 1.8 sir. VW gets 90bhp more out of some of their engines, just by a slight turbo tune (and of course pressure increase). But you are right, they dont like it, but its very doable! However im sure an EVO is a lot more fun to work with and own!
couldn't be further from the truth. The CLA45 engine can be bumped from 360hp to 400+ hp with just a tune. Add a downpipe and a bigger intercooler and you are talking 430+ . People are already doing it, with ease.
As the turbocharger uses sliding bearings i wonder whether this car has turbo timer. As a car switches off the engine cooling oil is not supplied to the T/C.This will literaly cook bearings resulting in an unbalanced T/C. I have seen videos this car doesnt have turbo lag. Turbo lag is the response time from the engine when you hit the pedal. However turbo lag protects the T/C from rapid changes in exhaust gas pressures. I suggest you after some km to check the spaces in turbine side on CLA
Yes, it does have a timer built in. I had a gla45 amg, and when I first got it, I kept wondering why the car and fan was still running after I parked it and went inside my house
Its not built any cheaper, build quality of the R32 is supreme, you obviously have not driven one. It is so much different than a four banger with alot of hp. Cheaper in price yes but not in quality. Put a supercharger in the r32 and this Benz would get left.
yo me compré nuevo el a45 de 381cv, me parece soso y le falta alma a ese motor,no estira nada, cuando esperas algo de atada derrepente se acaba y corta a 6300rpm, a mi no me gusta el comportamiento de ee motor,me hubiera gustado que subiese a 8000rpm con patada
