Hammann

[bfi2906]

Any one got a view on these guys? They've been around BMW's for years. the were the first to show-horn the 5 litre V8 into an e46 M3. So clearly, they think like most BMW people. And as we all know, the 135 is sorely lacking and needs more Kw's and Nm's. :biggrin:

They seem to do quite a good job on the 335, so no reason why they couldn't on the 135 - http://www.hamann-motorsport.de/56.0.html?&L=1

How's that comparing with other options?

Looking at the JB3 specs, there is really no comparison.:wink:

JB3 claims a massive 59KW increase at the rear wheels on the 135i and 100 Nm torque increase.

Any one out there to correct me on these figures...:iono:

[professor]

the last time i checked with them all they had were RHD floormats for the e82. perhaps, check what they have now for it??

also this looks like you will need to ship your ECU out to them while they reprogram it (like i discovered would be the case with noelle too)...

This looks like it might be easily plug'n'play. Peak in Sydney are the agents for Hartge

Hamann (and Hartge) are big tuning houses that have been doing Bimmers for years. Their tune will be expensive just like the AC Schitzer. There is a Hamann tuned and body kitted (CF body kit and wheels) F430 spyder in my building. Looks nice.

[WAY]

Zuzu, I like what Terry has done with JB3, but it isn't a tune for everyone. I have been spending hours on his forum (N54tech) doing research on this tune. It gives massive power, and obviously is trouble free for users. But people need to know that he gets this sort of power not by some magic, but by upping the boost level to 15psi which is just below the trigger point of the V81 ECU. He uses the smarts build into the factory ECU to regulate his boost etc, which is good. But I know for a fact from talking to many here that some people just don't one the added stress of having such high boost. No one really knows the long term implication of having higher boost. For all we know, 15psi may not be stressing the engine at all. Even my AA tune that is 12+ psi may be too high and we may be stressing the engine. No one knows, but of course in general, the less the boost the less the stress. My advice is this. If you want to be tracking or racing your car, don't be pushing the envelop unless you are willing to pay to rebuilt the engine if something goes wrong. No one really knows the long term implication of chipping on this engine. What I would say though is that if you are just driving your car in the city with little WOT, then JB3 would be no issue. But if you are using this as a track car, go for the more conservative products unless you are willing to pay for engine rebuild.

[Zuzu]

Hi Wayne, I have no intention of tracking my little vert, just looking for a bit of extra power now and then for when I am re-living my hoon days..:biggrin:

The points you have raised really are alll well informed but have no consequences with my intended usage of the car.

I am now just sitting back for the next few weeks and reading and watching all the reviews on your car and soon, Kris's car.

I had all intentions of purchasing the JB3 but seeing I just missed out on the initial delivery's, I will just wait and see.

From all the reviews and feedback on the forum , I would say I am leaning towards the JB3, like I said...It is only for street use and I wont be blasting the bejesus out of the car on a regular basis.:smile:

[WAY]

I am not trying to discourage anyone from whatever chip they choose to go with, but just want people to understand that you don't get more power magically. In fact I am an advocate of chipping, but I just want people to know what they are doing. The higher the numbers, the higher the boost. Simple as that. Or you can do things like getting free flowing DP or exhaust which will also help you get the higher power.

[WAY]

Btw Zuzu, I wrote that more for others and not for you. You are well informed, and I think you should just go get yourself a chip! :P

[Zuzu]

Wayne, like you, I to spend hours scouring over the forums with my huge appetite for information.:eyebulge:

I just sit back and absorb and now and then have my say,if I think it might be of some help.

I have always intended to mod the car, but I am one of those research freaks who has to be 100% and wont try anything for the sake of it.

Any info that comes my way i will take in regardless of its correctness and conclude with my own research.

Interesting, I actually looked into this one 5 years ago, (but the cost put me off in a hurry) when I was on the verge of buying an E46 M3 vert and was dissapointed BMW didn't fit it out with a V8, alot of people don't know, but that's the original reason for the quads on the rear of the E46 M3, BMW did plan to fit the M5's V8 but were 'scared' World wide M3 diehards would rebell (similar story to why Porsche won't change the rear engine layout of the 911) and then stuck to the old n/a IL6, albeit revamped.

So not sure that BMW think like most of us, but finally they've developed and installed a V8 in the current model M3...

Also, I for one certainly don't think the 135i is lacking in power in stock trim, sure if you can get more and get it easily, which is the case with forced inducted engines - why not :biggrin:

Which then brings in the next point as mentioned by others, there are better available tunes out there for a whole lot less money :wink:

[AussieRacer]

Wouldn't be so sure about the quad exhaust thing.

Long before the E46 M3, M cars with straight sixes were running around with quad exhausts:
