i had to replace the rear turbo assembly off of a 335i due to a faulty wastegate. thought you guys might like to see the size of it.

 

Wow I have that same phone, I can see how tiny they are.

 

Could be one of the reason's there is pretty much no turbo lag. I had the chance to drive one at a BMW driving school and it was amazing.

 

try the 135i...even better!! i might have to lease one under the employee program

 

wow. So the greddy turbo is like 8 times larger than this thing. lol

 

wow that is crazy small...exactly why they spool so fast

 

it's pretty wild how some of these 335i guys are running 11s

 

whats your take on how long those turbos will last running 11's?

 

wow that's bite sized.

 

I have only driven a turbo once, what do you mean by lag?

 

he means boost thresh hold. it's hard to get turbo lag in a street car.

 

Thanks

 

well in the case of the 335 you start with an engine that already puts out nearly 260hp NA, so a couple little turbos go a long way...still proving the adage no replacement for displacement.

 

Nice Pics, Thanks. I have an E92 335 and I was looking forward to the new 135s with the hope that they would be significantly lighter than the 335 and that BMW would have another 2002 on it's hands. *sigh*

Wishful thinking I suppose, still digging the 135 but just wish it were significantly lighter than the porky 335.

Anyhoo, again great shots, thanks a bunch.

 

Sadly, the misuse of the term "lag" for turbos is just about everywhere -- even from manufacturers' websites.

 

Looking at the 135i myself - it is a little porky.

Actually a lot porky, but still looks like a lot'o'fun.

Throwing the term "turbo spool" into the mix. Some folks seem to use this term for boost threshold also. At least it feels more appropriate than turbo lag.

 

True.
I hear the rear mount turbos have significant lag due to the piping length. I wonder why this mounting solution is still practiced.

 

so on the freeway a 335i pulled away from me...he was quick but once i downshifted to 5th ,my brothers 08 M3 pulled away real bad, thats crazy stuff
