Official BMW E92 3-series thread (UPDATE - 335i Dyno pg.48)

Me too, although all reports indicate this doesn't act like a high strung engine. Power seems immediate and smooth; both "reviews" I've seen have commented on how it feels like a really powerful NA engine. I don't know if that's a good thing or a bad thing.

I need to research the BMW turbo cars of the 70s some more.

Though I would rather go the natually aspirated route to 306hp.

What I'm somewhat surprised about is the curb weight. At 3571lbs, the 335i Coupe isn't exactly the lightweight vehicle you come to expect from BMW. The 335i coupe gained quite a bit of weight compared with the outgoing 330Ci.
People made fun of the new IS for getting "too porky", but it looks like the 3 Series will be gaining weight too.
Expect the 335i sedan to gain a similar amount of weight as well.

Please refer to the previous reply by akhbhaat regarding this issue in the same thread.

I usually like NA route, but have you seen the tq curve of this motor? it's crazy. 300ft-lb of tq at 1500 rpm
#401
NA engines, though, are usually less trouble to own and in general are more reliable. With turbos, the kind of oil you use and frequency of changes is more critical ( synthetic is usually best ), you have to do slow turbo warm-ups, idle the engine for a minute or so before shutting down to allow the oil pressure to keep up with the turbo spool-down, put up with turbo lag on hard acceleration, and possibly replace the turbo as well.......they often don't last the life of the engine itself.

I think the idea behind this engine is to mitigate some of those issues, in particular long warm ups and turbo lag. We'll see, but both initial reviews have commented on the distinct lack of tubro lag. The car has 300lb/ft of torque at 1450rpm, so I can see how that'd be so. I believe with the way they build the engine it weighs something like 6lbs more than the inline 6 in the e90. They say they did this because they didn't want to throw off their weight balance. I dunno.
As for weight, as XeroK00L mentioned BMW list unladen weights, so when comparing to other non-European cars you should subtract a couple hundred pounds to get an accurate comparison.

I agree that you have to allow the engine to idle for a minute or so before shutting down can be annoying but that's what Alarms with Turbo Timers are for .
Turbo's do last the life of the engine itself if taken care of properly. Your average joe who treats a turbo car the same as a NA car will kill the Turbo's really quick. IIRC The turbo's used on the Aristo's/Supra's are good up to 200k miles if looked after and maintained properly. I've also seen 180k mile Audi A4 1.8T which is still running perfectly in terms of Turbo/Engine (never rebuilt).
Also the fact that a Turbo is MUCH easier to get nice power gains out of whereas with a NA engine it's pretty hard unless it comes factory detunned like most of the Chevy blocks. Stick a boost controller on most cars and sort out the breathing (exhaust, air filter, decat, etc) and you'll see an easy 50-60hp gain in general on most stock turbo cars.
If BMW allows chipping, etc (like Audi, VW, etc) then we could see 350+ bhp 3ers running around looking completely stock!! Maybe even more!
I'm not a BMW fan by far, just trying to correct some of the assumptions here about Turbo maintenance, reliability, preference, etc. You really have to drive a turbo tuned for response to comment on it, and I doubt BMW will build some sort of lag monster. Just look at that torque curve, but then again take it with a grain of salt as it's from BMW regarding an unreleased engine, as the dyno's done by people will show the REAL curves when the car has been released.
IMHO, Toyota/Lexus needs to bring a Turbo monster, something like a bigger brother to the 2JZ-GTE. Too bad everyone seems to want to go Aluminum V6's nowadays .
On another note, I'll always be a diehard Lexus fan! I'm going to get back to researching and buying more mods to stop all the BMW fanboys from tearing up my Aristo with their 3.0 Bi-turbo's
#404
theres not gonna be any turbo lag because the boost is low the old engine was 255 hp and now its 306 with turbos, that has to be around 5-6 psi. Ill be skeptical about its durability, even the M3 engines which were N/A had many problems, hopefully they strengthened the internals
