I emailed ESS avbout a Supercharger!!

[sixspeed]

I've also been in talks with a company here about the ESS kits that are due also...

550bhp is the expected output....

Anyone got a BS smilie? A tuner has suggested a more than 200bhp increase from supercharging, and everyone seems to be taking it as gospel - I would be very, very, very surprised if they made that much of an increase.

Look at S/C installs on cars like the S2000, Monaro VXR and 350Z, they all get about 100bhp, and to be honest, I think that would be a better level of increase for the Z4M - around 440 bhp would do very nicely


ps - what is the exact bhp fig for Z4M's? I've seen 343 quoted in various places, and 330 in others

Alex,

Prepare to be very, very, very surprised then 550hp isn't that unfeasable.

Active Autowerke already produce a 525hp supercharger kit for the E46 M3 which uses the exact same engine as the Z4M.

550hp is entirely possible. Although I agree, I'd like the option of a tamer 420/440bhp as well - but with a charger, that can usually be achieved as simply as using a larger/smaller pulley (depending on how you look at it), and reducing the peak boost output by running the charger at a slower speed.

I'm a little concerned that it will change the characteristics of the car though. I mean, a Z4M is about loads of power at mega-high rpm, not gobs of torque at low rpm. If I'd wanted that I'd have bought a TVR Griffith

Very impressive then - but I guess changing the pulley size is similar to turning up the boost on a turbo - the more you go for, the shorter your engine life is likely to be.

Have there been any dyno tests of these conversions?

How is engine lifespan affected by superchargers.

It makes them last longer... they are like the multivitamin of the engine world!

i emailed Active Autowerke last week and here's their reply:

Sir,
We have not developed a sc system for that car as yet, we hope to do one in the future. The Zm4 has the same engine as the E46 M3, but a totally different engine management system. We have cracked into that software, but we have not fully developed the tuning for use on the Z4M with the supercharger. I am not sure when we will be doing that development. I guess if we get enough inquiries we will pursue that development.

Thank you for your interest in our products

i'd be interested in a 430-450bhp kit in a year or so.. hope someone does it
