The new 335i

M W · #1 (**permalink**) 01-27-2007, 07:50 PM

The wife and I are thinking about this one. I was wanting a Subaru STi as of late. A turbocharged powerplant is what I want. My wife keeps suggesting BMW. I'm a little shy because of the newness of the 335i.

So I decided to price one out. MSRP, the BMW is only 5k more to drive off the lot. That may be nice. Has anyone had a chance to drive this car yet?

We plan on checking one out in the near future, and possibly take one home. She wants my car.

I am seeking other opinions to assist me in finding things to look at, as well as things to consider.

Any inputs?

335xi is slated to come out soon, and the powerplant is unequalled for anything under 65k. I have a newfound respect for STI's after having ridden in them recently, but there is no comparison. I haven't driven the 335 yet, but I've seen them in action and I was very impressed.

I definately agree with you james the 335's are very impressive and with the XEDE perfomance stages the car is hectic. Plus xede doesn't cost much. Probably talking about new m3 specs for performance.

The new Xede stuff will give the M3 a run for it's money. On a track the new M3 will likely be faster because it was engineering to be a 400+hp car, but a flashed 335 in a straight line will be hard to beat - especially once an aftermarket LSD is made for the car.

What bothers me is the fact that there are twin turbo's that are tiny to increase spool up time. Does anyone think this will be an issue when a new map and exhaust is added? I think it may push the turbo's past their effeciency range. Then again, I am not aware of the turbo's specs.

I don't see how a new map and exhaust would push the turbos past their "limit". You would have to actually increase the boost to push the turbos any harder. I don't know how much (if at all) a new map would increase the boost, it would probably just make for better airflow. I know the exhaust upgrade will not push the turbos any harder, it will just let them spool faster.

Many of the new maps available are not increasing boost. I am sure that is the next step, but huge power is already being made without increasing boost.

Okay, with that being said, if you're not increasing boost, the upgrades are just going to make the turbos spool faster, giving you more power faster

But allowing the system to breathe better (TBE), could that cause boost creep?

No, the only thing that causes an increase in boost is actually increasing the boost. Even if it did, a pound or two of boost is not going to hurt the turbos. I'm sure BMW doesn't have the turbos maxed from the factory, so a pound or two won't hurt them.

I'm not worrying about the turbo's, I'm worrying about the motor. I know the STi's have this issue where a TBE is added, the turbo cannot pass the amount of exhaust fast enough, causing the turbo's to lean out your mixture.

I'm sure I'm worrying about something that shouldn't be worrying about. I'm pretty sure BMW has their setup dialed in, even if you add TBE.

I've never heard of a turbo not being able to handle a TBE. Adding a TBE to a turbo'd car shouldn't change the air/fuel ratio, and if a subi's turbo can't pass the air quickly enough for the increased flow of the exhaust, that's a crappy ass turbo.

92318is · #13 (**permalink**) 02-02-2007, 09:03 AM

Basically, if adding a TBE is too much for the turbo, that means that turbo is maxed out from the factory, and that turbo is a piece of crap.

I seriously doubt BMW's are maxed out from the factory.

The cars are hitting about 400hp at the crank without even turning the boost up.

Thanks for your input everyone. You are making me feel much better about chasing after a BMW. I appreciate it!
