    Gaz, which SC set up are you running again. Do you have a build thread?

    UPDATE #6

    hey chaps.
    running more voltage offset has improved the richness around the 5k mark. Its running real sweet now as hard as its ever gone really. Looking at the injector capacity at 0.6bsfc the 60lb/hr injectors at 80% duty cycle run around 625bhp. Im pretty sure the Ess chip is pretty marginal on fuel, I guess they would be perhaps around 70-75% which would equate to c/550bhp@flywheel. Im seeing around 11.8:1 a/f @ 7000rpm. Yes the trial pic worked so Ill get around in next few weeks to do a build thread, and get it on a chassis dyno to see where its all going.
    I dont know why many others haven't got the best out of thier supercharged setups. The std M60b40 copes with 10psi easy without a hint of detonation. My guess is it would cope even on RON98 (mon93) with 12psi without stressing things too much. With e85 perhaps 16psi, who knows. Lots of people dismiss the centrifugal supercharger, but its prob ideal for a reasonably high comp NA motor as it builds boost gradually. The only one that I know of who gone this far is 516SC but information from his build is even sketchier than mine LOL.

    Awaiting some powerflex black series bushes, weld in front camber bolts, rear shock mounts, custom blade adjustable rear sway bar + some lighter wheels. No point having power without control

    UPDATE:


    • Bushes have arrived. Also the weld in slotted bolt mount to allow front camber adjisent via the lower control a bush. Fronts have been installed and hope to have the rear done in next few weeks. I have the powerflex adjustable bushes on the rear so I can adjust both camber and toe.
    • Have made add an exciting purchase. Some electric sport seats (from a local Bimmerforums member here. Thanks Aden). I will dye them lotus white to match the rest of the interior. These will give more support for cornering and acceleration.
    • The triple step lips for the bbs rs metrics have been ordered so I can make a usable set of 18”rims from the old metrics.
    • An original Bosch 809 (Porsche turbo) maf is on the way from the uk. The 803 I have now is a chineese copy. It’s not as stable as I’d like down low. Hope the bigger capacity maf gives more tunable resolution. I’m relying heavily on the maf.


    Its been running pretty reliably with no belt grip issues. Can’t wait to finish the current development of the car and just have some fun in it for a while.

    Here's like 5 min of turbo noises. This was a few months ago. but still sounds the same haha. battling some wonky injector wiring at the moment so the car is down...

    EDIT: Jump to like 10 minutes in to avoid me droning on about nothing

    Sounds clean. Bet it will go nice when sorted.

    UPDATE:
    well unfortunately the 850csi 280mm clutch has started to slip. We are pulling out the subframe anyway this weekend so another clutch will be required. I have to send the whole clutch/flywheel interstate so they can install an upgraded material and improve the diaphragm on the pressure plate. I don’t want a puk clutch as no drivablility. Good news is the 809 maf is finally here from the UK. As the car will be off the road for at least a week ill think about removing the crank pulley and getting an 8rib made up. There is not much room to go bigger dia but I can prob squeeze another 10-15mm which should up the boost a few psi. Just what this car needs - more power again.

    UPDATE:
    as the car is off the road for a few weeks (common theme here) having the bushes installed and clutch redone (the 280mm clutch was stuffed good prob due to hydraulic issues earlier that didn’t help), I’ve bit the bullet and finally got the crank pulley off and going to remake it with 8 rib and 152mm dia instead of the 6 rib 140. According to vortech, with the 2.75” supercharger pulley I’ll be spinning the vortech up to 55000rpm which is about the max it can handle. I think this is what our friend 516sc was running. Vortech stated the 8 rib will grip much better and reduce the “phantom slip” and I should be close of just over 1 bar of boost. So much for being happy with 10psi. I guess if it’s too much I have spare a 2.95” supercharger pulley. I have plenty of fuel capacity up my sleeve as the reg is only set to 2.5 bar. I may end up running 50/50 e85 fuel as I don’t think I have the injectors for straight e85 unless I run the reg to about 4bar.

    We will see where the old ess kit ends up. Hope the chassis upgrades will help calm this beast im creating. Thought this journey i was going to create a nice 450bhp cruiser, not a 600bhp+ animal. Well if you do something u may as well turn the volume up to 11. Yes i will create a build thread.

    Update.

    Well it looks like I’m the only one playing with a supercharged 540 (except for mikk)

    Anyway the hard yards are behind me now. New clutch tailings and machined flywheel. All new powerflex or Oem bushes in everything, new drop links, rear shock mounts, dog bones, welded in lower camber adjusters, new ferodo ds25000 brake pads, the list goes on and on. Anyway gearbox is back in, front end being assembled, and about to put in rear subframe in next few days. The bigger dia crank pulley will be held up slighly so as an interim item I’m getting the original ess pulley have an extra 2 belt ribs installed to run an 8pk belt. I’m also running dial 12” thermo fans. My new triple step BBS RS wheels are pretty close also. Even the sports seats have been repaired and nearly ready for dyeing with the airbrush. Hope by the end of next week the 540 is back on the road tuned with the 809 Porsche turbo maf. The chassis will be great. I’ll have full front camber & toe adjustment on both the front and rear along with fresh rubber. Not sure whether to stick with the trusted Michelin ps4 or try the new hamkook rs4.

    As as an entree, Just done the front of my old 2002 with new bushes and some negative camber. It drives and handles so much better it’s like a different car.

    And yes I’ll do a build thread and possibly throw it on a chassis dyno. Not long now. Nearly 3 years to develop it to this level. Hope it’s worth it.

    Not quite true . New charger bearings, belt and pulley arrived from 928 motorsports. Modifying charger housing to incorporate vent holes for cooling. Waiting on modified PCV blanking plate from AAS and then retune of ECU with water/meth.

    Expecting ~420-450whp at 7-8psi.

    I am still playing. Just waiting for race season to be over so my tuner/engine builder can install their stand-a-lone/harness and then tune.

    Nice to see some others playing.

    currently at 10psi. Should have the modified ess pulley back early next week which may yield another psi or so due to more belt grip. We shall see. I have plans drawn up to go from 140mm (ess) to 152mm in 8rib (with the 2.75” blower hpulley) which will see around 54000rpm(supercharger) @7000rpm (engine) which is about as much as I wish to push it. It will be great having it back with a controllable chassis and good tyres. Can’t wait. It was real strong before, no idea how it will dyno on the chassis dyno. I’ll just say 400+ rwhp then I won’t be disappointed.

    Ordered an AEM failsaife gauge that monitors a/f, boost, and ethanol content. I can adjust it to cutout with any set of parameters mainly lean running when at boost. Not cheap but when pushing the setup abit it will save an engine.

    Next update will hopefully be driving impressions.

    UPDATE: Driving impressions.

    Well all is back together. Done the mad dash to the wheel alignment shop with 20mm of toe out on the right front. Got a basic alignment dialed in with -2.5seg camber on the front but couldn’t get the powerflex rear subframe bush to rotate on the left side so we will have to go back Wednesday arvo with my mechanic and a series of punches. Even with a compromised alignment the new. Bushes and linkages have totally transformed the car. It’s s massive job but well worth it if I plan to keep your e34.

    The porshe 809 maf is in so is the 8rib pulley/belt. Firstly tuned for full throttle at max rpm mechanically by fuel pressure. We now have 13-14 psi at max rpm and tuned to 11.8:1 fuel mixture. By got the top end is now very aggressive and the well worn pilot superspots can’t get the power down to 3rd gear. I’ll get the fuel interceptor computer wired in today and start tuning it tomorrow. Now it’s ok at it’ll and part throttle but heavy throttle in the 2500 to 4500 rpm zone are as rich as 9:1 so as it tuned it’s only going to go harder and harder through that range.

    Its scary fast. We are seeing 75% injector duty on 3.5 bar(with 0.95bar boost) on 60lb/hr injectors. Hopefully all goes well tuning on Sunday. For those with supercharger systems they are playing with use an 8pk belt. Picked up 3psi without any pills dia changes. I have a larger crank pulley drawn up and ready to be made if need be but I may have to reduce the dia as the +12mm dia increase will prob put me at 17-18 psi on pump fuel.

    Anyway by by mid next week I should have the car back and start on some cosmetic upgrades and the mechanical ones will be sorted finally.

    3 weeks on and car hasn’t missed a beat. Been slowly putting stuff back on, tidied up oil/air seperator plumbing, our back engine covers etc etc. I’ll do a final tune in a few weeks to get rid of some richness in the lower rpm WOT ranges. My bbs rs should be ready in a few weeks also. To celebrate photobucket being working thought I’d bedder do some pics as the text only updates are not visually stimulating.

    Hell yes, Gaz. Those RS look epic and are very motivational for me

    Looks like your pulley package arrived today! Hope it arrived ok. Also looks like I swapped an O for a 0 (zero) in your tracking number; my apologies!

    A small update, just replaced the 2 narrow band sensors and now the idle is smooth and consistent with stable AF ratio. It’s early days but seems a worthy thing to replace. I also replaced the body control module as I was getting a coolant low error with a new sensor. No more coolant error. Just down to one now the brake sensor. I’ll do a reset this morning. Hopefully next update will show some shiny new bbs wheels installed.

    If you were to do this again would you go turbo or superchaeger?

    I would do exactly the same again. I think I can get even more power out of it, could prob run 16-17psi on pump fuel. I’ve got about 7000rpm of supercharger capacity left. Currently it’s hitting 14psi.

    The only downsides I find of the centrifugal are;

    • boost peaks at redline and no boost to about 3000rpm, so less midrange power than turbo I would imagine
    • there is no decent off the shelf kit with good boost , proper inter cooling, at least 42lb/hr injectors, 809 Porsche maf, and 8 rib belt setup as u need all these elements to optimise the kit.
    • u are very reliant on the belt to be in good order to keep the power happening.

    Advantes (to me ) of the centrifugal over turbo.
    • enhances exhaust noise rather than dulling it.
    • more sympathetic for the engine internals
    • drives like a standard car to 2500rpm
    • not bad on fuel when off boost cruising.
    • more drivable in bad weather conditions as u don’t have that dramatic spike in power at 3000rpm or so
    • makes power to the 7000rpm cut & revs like crazy, feels the redline is 1000rpm early.
    • it’s easer to modulate throttle to enhance tyre grip.
