Tuned 335i and downpipes dyno?

Hey guys so I have a jb4 and ER downpipes on my 335i. I was wondering if anyone knows how much my car is pushing now. Sorry but I couldn't a thread that had this information.

Thanks in advance!

About 340WHP. Might be able to squeeze a little more with intake and even another 20-25WHP with E85 @ 30%.

Anybody else find it sad that even with a tune/DP/intake we are still a far cry from 400whp?!. I really hope the next 335 has more to offer for us power wise.

JB4, downpipe, and an intake on Map 7 with either E30 fuel or 100+ octane nets you 400+ RWHP. A member with a 235i made 400 RWHP with the only modification being a JB4 on Map 7 running E30. So, no...not a far cry at all.

Regardless of this, what exactly are you expecting? 450? 500+? We're talking about a standard, run-of-the-mill BMW commuter car here, not a Z06 or GTR.

The M3/4 on the other hand is a different story. You sneeze on them and they make 550 RWHP. I'm almost certain I'm cutting my 4's lease short for an M4 as my next beater. Interestingly enough, with minor mods it will be almost as quick as my C7Z stock when it comes in.

I get what you're saying. The thing is yes it can hit those numbers (~400rwhp) but then we are talking mixing fuels running higher maps, etc. If we could do it with 93 oct and FBO/jb4 that would be awesome. I always said all I need in this car is a RELIABLE 400awhp/400awtq and id be happy as a clam.

Congrats on the C7Z. Im looking at picking one up in the not to distant future as well. Just sold my 900hp C5...now that car was insane! Just a different animal. I guess you get spoiled with all that power.

??? Surely not.
Delta between "at the crank" and "at the wheels" figures is much less than 20%.....340whp is more like 390-400chp at best.

You might be right.
