HPF Time for M Coupe!

[Evoking]

Goodness gracious!!! We have got to get access to the Horsepowerfreaks turbo kit for the coupe!

Now I don't street race, I've owned some monsters including Z06 and Viper. But I've always slightly preferred the scalpel to the sledghammer i.e. NSX, 993, Evo, S2k, 968 for example. But holy cow! When you consider how far down we are on the totem pole it can be depressing.

When I had one of the legendary scalpels - NSX - I knew a supercharger would be the ultimate becasue it could then run with Vipers yet be refined and precise. But even it would be outgunned by many here.

That freakin 911 C2S which seams tame compared to the GT2, LP-640 pulled all over the R8 which would cream us. And it also pulled all over the E92 M3 which would pull on us from a roll as well. So if cars that would spank us seem slow where does that leave us

http://www.m5board.com/vbulletin/e60...rger-more.html

I know, I know, the C2S is a $95k car and all the ones that beat it are north of $150k so what's the big deal. Well there are C6 Z06's for $40k, E55's for $30k, and Viper SRT-10's for $45k. Yes, I love the total package of my Coupe, but sometimes it seems we're not even in the game...

One could sell their M Coupe for a loss, cough up $45k on a Z06, Viper or $30k on E55 and end up missing the "scalpel"

OR

One could inject some "Sledgehammer" into their scalpel via HPF!
Look at what happens when the lowly HPF E46 M3 hooks up against that Superlegerra! I could never stomach even $10k superchager on my NSX's much less $18k on HPF but it does make me think... If I still have this thing after warranty is up I may have to do it!

Anyone done this yet to M Coupe?

Different ECU, too limited a car for them to produce for and see a sizable return. That being said you can purchase some of their kits and components separately, I'm sure with enough time and money you could integrate a standalone into the Z4M to make it work.

[xjeeper]

We have the MSS70 ECU which is very similar to the M3's V8 and the M5's V10 ECU's. HPF uses the the stock e46 M3 ECU for various simple functions and then adds on a proprietary version of an AEM box (If I had to guess, I bet it is the FI/C box they have modified to their specs)

If you bought their manifold(s) and turbo with related plumbing.... made your own intercooler setup and bought an AEM FI/C it may work. Maybe.

There will always be something faster - you can live with it, or spend a shitload of money and then live with it. Those are the only options.

Still faster than a Cayman S. And those are still $75,000 new with options.

[Evoking]

Maybe not... The new Boxter S is stupid fast. 0-60 in 4.3 and 1/4 in 12.7

I was blown away to see this in a test in R &T or C & D can't remember which. I guess now that its over 300hp its putting up unheard of numbers!

I don't think that's right, it has 310hp and weighs in at 3100lbs. That's roughly what a Z4m weighs with less power.

They have new super short gearing i believe, which is getting them pretty decent 0-100 times.

[epbrown]

The final drive ratio has always been better than the stock Z4M - the Porsche is 3.88:1, compared to 3.62:1 for us. This is one of the reasons I upgraded mine to 3.91:1, and why I feel the Z4Ms should have come with the motorsport gears stock. Fortunately, you could buy a Z4MC, do the upgrade, and still come in well under the price of a Porsche Cayman S. The 3.91, in addition to the extra power and stock LSD, would have had the Z4Ms spanking the Boxster/Cayman in comparison reviews back when they were launched in 2006.

[O-cha]

Your best chance would be to swap the e46 ecu onto your engine, and then customize the kit to the z4m. It's actually not as difficult as it might seem, just the loss of most of your functions is the sucky part.

That is your best and only chance really, HPF have no interest in doing it and it has been discussed.

[DiscoZ]

Subjective rant: Bullshit American mags love the Cayman S, always have. It's easy to drive for those morons. It should run with a Z4M:, shorter gears and less HP. the cars weigh about the same too, given the different weight conventions used by Porsche vs. BMW. Mag racing...

It did spank the Cayman S in a number of comparision reviews. Unfortunately for Americans, these were by Eurpoeans and not the usual American crap-mags.

Not really.

I won't let you get away with that.

According to the Porsche USA website the Cayman-S has a 0-60mph time of 4.9sec for the manual trans model.

Power is also quoted at 320hp/235kw.

Which European mags? I read/collect Car and Evo and they both prefer the Porsche Cayman S as well, despite Evo being quite sympathetic to the Z4M.

After owning a Z3 and driving the both engine variations of the MZ3 extensively, I have always felt that 300 + hp should have been the standard for the Z4 models not the M version. I could not bring myself to get a 3.0i or si after driving them. I am pleased with my M roady and the road feel of BMWs in general but having owned vettes and growing up in the era 400+ factory motors...even the new M3 power doesn't make me swoon.

[blender]

I have to say the acceleration runs in the clips are very impressive. Who doesn't like more speed?

However driving around LA, I rarely get the opportunity or desire to run the car above 100ish MPH, and the most fun reliably comes in the 40-70 range carving up some very twisty roads usually posted at 25MPH. Any faster than that on tight twisties and one can easily over-drive the tires in [nearly] any road car.

My other point is that while a straight-line blast of acceleration is Very Cool, it doesn't LAST for three hours like a good drive through the twisties can.

Getting into the zone of operating the machine really well, forgetting the world and practicing my car control is more enjoyable [for me] than the 30 second adrenaline rush from a freeway blast. It's safer, attracts less attention from Loss Enforcement, has better scenery, and can be done with the top down and the radio up approximately 52 weeks a year in SoCal.

Oh, and the Z4M is a great car for doing exactly that: more than adequate performance, very good handling, style, reasonable practicality, and not TOO fragile/exotic/expensive to justify the kid gloves treatment. It's a very fine real word sportscar. Would I like a Ferrari 599 in the garage ? Sure. Would the Z4M beat it in "Total Fun Hours Logged" ? Definitely.

That's my two cents, feel free to say how wrong I am.. : )

Well said... I concur and love the feel of the coupe!

[werke-t]

Ok this thread has gone wayy off topic with all this cayman crap, but OP if you really wanted a HPF z4mc, i would buy thier kit, install it on your car (if you can or if it even fits) then just send it to HPF for custom tuning. Yes it will take a very long time, and cost a ton of money, but i bet HPF will do it.

Im sure they do not want to make a completely different kit for the Z4MC, but if it bolts up like on the e46 im sure they would tackle the challenge of custom tuning your one-off coupe.

So whoever has 20K and wants a "super car fast" BMW should try it out.

Oh and for what its worth the e46 m3 and z4mc ECU's are very different, but they are also very similar, they are obviously running the same motor, but from what ive heard the z4m computes faster and has more info for the updated electronics. The people to be talking to about the ECU would be ESS, because they currently are one of the only tuners who have FI'ed a Z4mc and e46 m3. They will obviously know the differences in tuning them.

This might be a little sneaky or unethical, but if HPF absolutely will not tune your car. I would have ESS take a good look at how HPF ecu works and adapt the tune for the z4m
