BMW z4m supercharged

[Beedub]

i thought id bring this thread back after having this kit for a good 6 months now....

so firstly heres a vid of me on track, notice im slightly struggling to keep it on the track..

http://www.youtube.com/watch?v=Lwi2YzM6EpM

secondly.. alittle review, the car with the new alpha N management is just perfect, idle is BETTER than stock, absolutly digially smooth, low speed drivability is just fabulous, the car pulls from very low and i just an actual joy to drive slowly as well as at speed, its really nice to have done a mod thats added to the all round appeal of the car.

once upto speed the car is a hammer, pulling cleanly to 7900 where my 5.5psi is made, proper calculations show im hitting 21mpg when not pushed (actual empty to full calculations), the traction control flashes till the mid range of 3rd gear, Vortech v3si is a self lubricated s/c unit so doesnt share my engine oil, it has its own oil reseviour, the cars oil and water temps are kept completly as they were before i F/I'd the car.

Ess's support has been amazing, any glitch and these guys are here for me, overall im very happy, the kit is oem quality, looks amazing and its a ball to drive, so far ive done about 3 trackdays with another this saturday..... anyone with the s54 motor, this is the way for more power.......

cheers for reading guys

cheers matey really chuffed with it.......... the track is actually curborough sprint course, its not where near as easy as it looks to navigate round quickly, off camber corners, low friction surface patches and NO runoff, the mole hill can give a grown man nightmares, very techical, more importantly its local and im a scc member so sprint here reguarly, its nice to give the car a challenge and this is the place, difficult to build boost, punishing on tyres and brakes ;-)

its really that loud...... the drone at motorspeeds is the type of drone that rattles your bones, the sonic waves that emit from those pipes makes my eye lashes vibrate, great 90% of the time, horrific in the wrong instance, luckily i only drive it on the weekends! lol

You need more videos!!!

ok heres another view....inside

Is that a custom exhaust, or off the shelf?

[Beedub]

its an off the shelf system, a straight pipe design with lightweight and free flow first prioritys, the weight is reduced but 60% over the stock items, the exhaust was imported from the us, one side effect is its massive noise, in some ways great, other ways not so great, it does scrape the uk track noise regs nicely usually being at around 97db at 4500 static tests.

uuppddaattee!

Guys alittle update here.....

ive just purchased AP's 6pot 370mm front and 4pt rear brke kit/pagid Blue pads for the car.......The brakes are MASSIVE, i cant wait to get on the track again with these fitted and really do some work!
unfortunatly the install is up to me as i now have £0 money left!!

i also went for a stud conversion and kics r26 composite open ended wheel nuts....

The car has also had a slightly more aggresive tune with the most aggresive vanos setting and on 100octane fuel the car made a healthly 461bhp....

i will update with pics shortly.

One thing I'm very cautious of is tuning a car that was factory designed to be n/a into a low compression FI engine.

Admittedly the easiest thing to do is bolt a s/charger onto the M3 engine and the power gains are fantastic. However, I worry about reliability.

Have you had any problems at all with the installation e.g. slipping s/charger belts, over fueling on the map, overheating?

It's a very tempting prospect, although the sound of the CSL airbox is calling me as well.

david this kit has been on e46 m3 for 10 years, the evolution is this vt1 kit for the z4ms, ESS have soo much experience in this field its unbelievable....... i researched every possible aspect of the kit before i jumped in, this is the lowest boost pressure available @ 5psi, and the car performs fautlessly, theirs no hiccups, no stutters, no fueling issues..... if you know much about these cars or the s54 you'll know ESS are reknowned for their kits, and the support they give is next level.

the cars map is completely adaptive, so bad fuel will cause the ecu to pull timing, good fuel it will advance....
the cars performance is solid.... email them and get the detailed info on the packs they do, the s54 is germany's 2jz ;-) forged crank, already their for you ;-) this isnt a one off test this is a developed onver thousands of thousands of miles on countless cars..... if your car breaks these guys will be here for you!!!

the power is mad....... heres a poor vid someone sent to me of mine...... i wasnt going hell for leather here as i was datalogging ;-)
