Best way to get top end power?

Chicks-Love-Bimmers · 08-30-2011, 01:34 PM

Ran a E46 M3 and they surprisingly have really good top end power (passed me in the twisties), but I'm running a tune and intake with some coilovers. What should I ideally get after downpipes, a BOV/DV or FMIC? I also hear that a BOV or DV will help stop some of the rattling noise.

Its the nature of turbos..N/A will have better power up top but keep in mind we rule when it comes to torque..which is what really counts..

DPs, Intake, full catless exhaust, FMIC, and ''proper'' tune will get u 400+HP and torque

Do you know if the M3 has a tune? What tune are you running?
Your next Best upgrade is DP's and IC. You should walk even a modified e46 after these upgrades.

jdbretz · 08-30-2011, 02:47 PM

DV/BOV will not add any power, and won't help with wastegate rattle. After DP's a FMIC or Meth is a good next step. Honestly though, you don't need anymore top end to run down a E46 M3. With a tune alone (assuming you are running a JB3/4, Procede, Giac, or COBB) you are way ahead in terms of power and should be outing running him without trying. The M3 has a better suspension though than a 335i with coilovers.

Gt42R single turbo would do it. Upgraded Heads. Upgraded Cam.

Chicks-Love-Bimmers · 08-30-2011, 02:53 PM

Would meth be ideal if I plan on keeping my car for a long time? I hear it's not good for the turbo's longevity.

Meth is an active mod...you have to really monitor the system..fail safes etc..go w FBO passive mods and you will be at 400+ mark

Where the hell did you hear that from? I guess you could make an argument that running meth will allow you to run higher PSI, placing more strain on the turbo, but in no way does methanol effect a turbo's logevity.

STage 2 turbos :-)

Q4P · 08-30-2011, 03:00 PM

As far as top end power is concerned I would definitely go for the meth/intercooler combo. A DP is important but it is much more for responsiveness and spool time... Either way, definitely FBO + Meth will be the best options for top end power on this car outside of upgraded turbos.

Would be nice....however, I realize there may be some room under the hood after pitching the 2 hairdryers for the one big one. The reality is that the 42R's are massive, you could hollow one of those bastards out and raise a small family in one. What about injectors, fuel pressure, MAF voltage, custom tune, etc. These things need to be factored when making a massive HP jump. It isn't that cut and dry.

Sell the car and get a c6 zr1.

Correction, free flowing exhaust is key for high speeds, especially for turbos.

Possible thread fail...sounds like a handling/driving prob versus powah

Get the E9x M3 suspension goodies and sticky wheels/tires and you will no longer 'lose 'im in the twisties'.

Don't read me wrong, I'll be first in line when a compatible single turbo is available for the 335. I guess it's a waiting game till then.

but FBO+meth and no downpipes will be a sure turbo killer imo! way too much backpressure on them with the kind of PSI the will be pushing with the additional help of the meth and IC!

to me the propper order would be TUNE, IC, DP's, then Meth. you will get more power doing the downpipes first but you will be running higher iats with the due to the higher power output and more boost from the tune. i'm no expert, this is just my gathered experience!

Tell that to all of the people that run meth and have no bolt ons at all at 18 psi. Yeah, I would question it too but some people seem to do alright with it.

It is my personal opinion that you should do tune, intercooler, exhaust (including downpipes) and then meth but people will always have different opinions.
