Exhaust mods for 97 e36 M3, are they worth it? |
|
|
Hi all, does anyone know if fitting extractors and modifying the air intake
will give and extra 50kw to an unmodified e36 M3. I've been told that they
have a restrictive exhaust system and if you modify the air intake by
redirecting the intake duct and getting positive pressure it is possible.
thanks in advance.

Whoe.... First where are you? What year ///M3? Does it have the S50b30 or
S50b32, or the US motor?
It makes a difference.

Hi My name is Hany, its a 97 s50b32 definately not the Us motor. I'm in
Sydney, Australia. I think the Us motor has only one intake throttle whereas
here we have six.
Thanks

So, in English... You are talking about an intake and exhaust headers giving
50Kw by themselves?
Your car had some very nice headers already from the factory, so I don't see
a lot to be gained there. There are many aftermarket intakes available, They
all have pros and cons.
An aftermarket chip, or ECU upgrade will give you the most improvement. In
Euro trim, the S50B32 was rated for 321Hp. I have heard that adding a
Unichip would boost that to the 340 range...
Headers don't seem to do very much on our US motors.

Thanks for the reply,
I didn't think that 50kw was realistic. I was told this on a recent track
day. I think track tyres and some suspension work are probably the next
step, but any suggestions are most welcome as to increasing horsepower.

Thanks for the reply your advice is well taken. the guy who suggested the
mods had an e36 325i and claimed by changing the intake hose position so it
accepts air from the brake cooling duct he gained an extra 15km/h down the
straight. He also has a hot little mini cooper with 15psi boost on the
supercharger which was running rings around us. It was as if it was on
rails.

Uh; yeah. We all know how much cooler it is there than behind the
right headlight. Tell him to show you the 'before and after' dyno
figures next time.

I know the type. More money than actual ability, so he *buys*
performance instead of learning how to do it.

your probably right after all he was the only one with racing slicks and a
full racing suit and shoes while we were all in jeans and shirts. Even a
professional dirver was on the track that day he was dressed normally.
What do u think about bridgestone re55's semi slicks? They have been
recommended by the tyre place I go to. I have road pirelli p-zeros at the
moment and they just get abused after three laps and start to let go as I
drift closer and closer to the edge of the track.

Yup. Seen the type. Scary. Might be quite capable, but offers
(often) unsolicited and (equally often) wildly inappropriate advice.
Would never say what I'm saying below:

Don't know. Never driven them. I used to run some RE-71R and some
RE-71RS tires. For two tires that were stensibly the same 'model',
they were wildly different in appearance. Both were autocross/road
racing 'R' compounds, though. Liked them a lot. Almost zero tread
life. IIRC, they were USDOT 'rated' at 50 and 30. If you want 'track
tires', there are lots of choices. Just don't expect any of them to
be worth a damn on the street for much more than about 10 sunny days.

AFAIK, that's a pretty decent high performance street tire. Either
they're old, you're overdriving them, or your driving gets sloppy as
time passes. The solutions are:
1) get newer tires or
2) slow down or
3) put brain in gear. Don't be insulted by this. Hell, it happens to
me, too. Toward the end of a session, almost everyone's attention
starts to drift. Oh; except 'that guy' ... ;^)

Thanks for the info and no offense taken, quite the opposite I appreciate
the advice. BTW what pressures do u run when you r on the track. sorry
another dilemma. I usually increase from 34psi for road use to 40psi for
track.
Thanks Again

I drive an E28 535is with a modified suspension, so it's not exactly
comparable. It also depends on the size, construction, and profile of
the tires you're using. Finally, it can depend on the track surface.
You are going in the right direction; track use normally calls for
higher pressures than street use. Get someone who knows what he's
talking about (look for the guy in jeans, not Nomex) and find out how
to mark (chalk or white shoe polish is popular among autocrossers and
'track junkies' here) and 'read' your tires after a session. I rarely
go to a track event where I *don't* teach someone how to do that.

Thanks again I will take some chalk with me next time. Just went through
some of the last track day footage, that mini was on steroids passing an M3,
lotus, Audi TT under brakes, flying round the hairpin, then rocketing down
the straight.
Thanks

Wow, somebody that takes something other than an M3/5 to the track and an |
instructor to boot. Pray tell us about your suspension mods, please.
I'll grant that "out of the box" an M3 or M3 is better suited to a DE than
a 5 series. But it seems to me that a 5 has a lot of potential that could
be realized with upgraded springs/shocks and somewhat stiffer roll bars
without completely sacrificing the ride quality.
Most of the folks that I know that take their cars out for a track day are
M drivers and they seem rather skeptical of a 5's ability to stay on the
track. Not having an M3 and needing the increased interior room of a 5er I
still want to do a DE and have been considering a suspension upgrade
to reduce the understeer to a more manageable level and otherwise improve
the general handling.
Oh yeah, 'cause it probably matters, it's a 2001 525 w/automatic. Yeah I
know the purists all drive manuals, but those are far harder to find in
the used market. And besides, I got an awesome deal on this one and in
Selectronic mode I'm not that far from the performance of a manual.
Out of curiosity where are you located?
