Supercharged E34 M60/M62's check in here

[NY Bimmers]

Well i finally get to check in here. Ess Kit on my 95' 540i/6.

It's already not enough and i'm looking for more. Debating between e85 or 93 with meth injection.

Does anyone know how much psi the smaller pulleys give roughly?

[imae30driver]

So I'm there with you. I've found a 500$ meth kit that actually reads off your MAF's 5v signal and or boost I believe and sprays accordingly.

I also have serious interest in e85 with its pricing and availability around me. The pulleys Cary in size for psi think 9-12-15 are the next steps and over 9 supposedly requires FMIC or Methonal perhaps just e85 even..

I imagine due to increases in ocatain that meth+e85 is overly redundent but intake temps would likely be great??? Don't know honestly

please pave the way sir

Also, from what I understand there may be issue with belt slip requiring custom addition of extra tensioners and or wider belts/or gator back belts as you crank up the boost. Could be expensive

Congrats man, hopefully this kit has less headaches than some of the other custom kits from the beginning of this thread?

For a rough estimate of boost increase from a smaller pulley, I used this calculator: http://www.928motorsports.com/servic...tingpulley.php

They have a library of step-up ratios, so if you can measure the diameter of your pulleys, you can calculate the max rpm of your SC now at redline. Then, you can change the diameter of the SC pulley to see the increase in RPM. Since superchargers are pretty linear, you can use that factor of [new max sc rpm]/[old max sc rpm] as a multiplier of your current boost. Of course there are several other variables, but it's a decent estimate.

I hope you have means of re-tuning for the bigger pulley and not using the ESS chip

Jon can explain it better, but I vote for 93 + Meth.

[NY Bimmers]

Yes, the ess tensioner setup sucks, there is no belt wrap, i was thinking of stepping up the crank pulley before going with a smaller s/c pulley. That would keep the belt slip issues at bay for now. I was planning on using the war chip for tuning. I like their maf setup also but $1500 is pretty steep for the kit, pretty sure i can go ms3 for less.

I prefer to stay with gasoline, i kept it on my turbo e30 and i'd like to keep it here. I have a few ideas on a water to air intercooler setup i'll be trying out eventually.

[imae30driver]

I wish the pulley for the crank was wider myself.

vortech makes an excellent water to air intercooler called the charge cooler but it's 2,100$ damn it!!! Was the plan till saw the price... I myself am going to be trying SSSquid tuning.

I just gave them a list of what I'm running and they made me a base tune and had it to me quick.(300$) half every rewrite) They also use programming to revalue the MAF's signal rather than doing a cheapy resister mod witch i really like.!

I was planning on miller but the cost 1600$ and fact that they only make a Blow threw MAF design bothered me. It's also 3" boost tube not stock MAF diameter so won't fit your current piping with out modification of some sort.

Let it me know what you do!

in case you were interested in just looking, it's still a strong consideration of mine. Wouldn't mind an option either myself if anyone has more experience with MI.

I've been collecting some bits to upgrade my ess kit. The 540i/6 will get some loving soon as it's got a few electrical gremlins to sort out and the dreaded no start at hot weather. I've got in my possesion the following parts.

• Porsche 803 3.5" maf
• new starter motor
• Warchip
• water/air Intercooler
• 8 rib 2.93" pulley
• Wideband sensor with a/f gauge

I need the following parts still

• Tune for the warchip
• upgraded fuel pump
• custom 8 rib crank pulley
• possible adjustable FPR
• a few silicone bends to rerun the piping
• some gold foil insulation for the Intercooler core

I hope to have about 9-10psi. With it tuned properly it should go like a rocket and conservatively make over 400rwhp. It currently makes 340rwhp which is pretty reasonable but without intercooling the heat soak I think knocks off 40-50rwhp making it not that much stronger than a well running std 540i.

If anyone has a base 540i supercharged miller tune this would be great and I'd be happy to return my custom tune when finished.

[imae30driver]

Awesome GAZm3 can you fill me in on your water to air inter cooling solution and its associated costs?

[imae30driver]

I FINALLY GET TO OFFICALLY CHECK IN!

started my car on boost for the very first time and it ran flawlessly, especially impressive for a adapted kit!

[imae30driver]

I have a CEL 1213 constantly on, lambda control 2 only.


the car runs well at idle for ever, makes one good pull them starts to run very rough. Shut it off For a bit and the cycle restarts. Being only lambda 2 not 1-2 I believe my issue I side specific.


has anyone here had a similar issue?

[GazM3]

Awesome GAZm3 can you fill me in on your water to air inter cooling solution and its associated costs?

The cooler package is only about $460AUD which is like about .02cUSD at the moment it seems.
Finally my mechanic has some time so will be going to him this Wed/Thurs, to fix the starter motor, solve the mystery poor running, possibly fit the new Maf. We will get the car running correctly first then bolt on the cooler with std boost levels. We have to also get hold of a Miller program for the war chip (404 dme) in supercharged form rather than starting from scratch. If anyone has a copy of this, Im happy to send them a copy of my tweaked version once its tuned to the higher boost and cooler. If the cooler is not enough to keep intake temps under control, I suppose the next step is some water/meth injection. With 9-10psi and consistent (coolish) intake temps we should be able to feed some timing into it and make some fun power. It would be nice to have a usable 400+rwhp ,which doesnt totally overpower the chassis, but still gets your pulse rate up a little when u drive it.

[imae30driver]

You got to link that affordable water to air intercooler solution for me please!

[GazM3]

no worries.
A few have used this before and it works well. You will need a remote filler (from a high point) with a radiator cap, and I would strongly suggest to foil wrap it with that gold heat insulating shit. The only doable loacation is parallel with the RHS cam cover. The RMS one looks better, but you will need to have some deep pockets. The benifit of this location is the pipework is barely any longer. A bit of a pain in the ass to change the spark plugs, and you have to rotate the supercharger so the discharge point is at the bottom but its only a little bit of fiddling. Car is at the mechanics now sorting out some stuff so it runs nice, then when I get it home ill bolt on the cooler and see how it goes with std boost first, then hope its good, and we can start to play around abit more

this is where the core is going to sit. Its tight but it fits snug. May need to get one of those VF engineering intake pipes or cut the silicone hose down a little

[imae30driver]

Jesus Christ that distrubeter is in my back yard thank you so much!!!!


excited about that! Looks great

- - - Updated - - -

Do me a favor please, can you confirm with no covers you can lay it flat on top of the intake manifold and still shut the hood?

[GazM3]

Hood shuts no problem. The only thing in worried about is the heat from te exhaust hence wrap the cooler in the best insulation foil u can. Also insulate the cooler "coolant" line so u don't gain 5-10deg from the path through the engine bay.

[imae30driver]

It shuts with the intercooler on top of the motor not where you want it right?

i saw an e39 with it right on top of the intake behind the TB I'd like to do that!

[GazM3]

I'm not sure about this. U would prob have to relocate the coolant topup resivior then.

I've been considering supercharging my 540/5 and found this thread interesting.

It seems there's no real bolt on solution and there's a lot of work to get the supercharger running properly which is part of the fun.

I've been building my 540 with the concept of having it 'supercharger ready' from the cooling system and exhaust point of view

Some of these modifications may help others be inspired to design something similar to solve cooling and exhaust problems they may be having

Cooling system

I'm in Jakarta Indonesia and according to Tom Tom we have the worst traffic in the World.

45 to 48 deg C road temps and lots of idling and low speed driving puts our cooling systems under stress.

I've spent 12 months solving the cooling problems on my 530i now M60B40

- custom aluminium radiator
- electric puller fan (E34 auxiliary fan mounted behind the radiator)
- double fan temp sensors from 318i (80/88 deg C) and E34 M5 (91/99)

Since the B40 went in the under bonnet temps skyrocketed causing some electrical and fuel line (went hard as a rock) and radiator hose failures (hoses bulging), water temps were ok and I've added some cooling vents to help the hot air escape.

If I did this again I would only do the 4 holes at the base of the windscreen.

The 540 runs cool now , around 90 to 95 deg water temp, water temp gauge is left tangent or right tangent to centre.

Under bonnet temps dropped from 90 deg C to 60 deg C

There's no electrical issues from the load of the extra fan , no more horrible fan noise and no risk of fan clutch lock up or fan explosions

Exhaust

Running stock headers at the moment as I like the twin wall design, this reduces heat in the engine bay.

A custom set of twin wall log headers may happen in the future or I will modify the original headers.

There's not much clearance down there.

Downstream of the headers as follows

- 4 x 2.25" 316 stainless steel pipes
- feeding into a 2 x 4.25" NASCAR style Y pipe (mild steel oval pipes)
- Empty stock centre muffler (to be replaced with a custom section)
- 1 x 4.25" oval pipe to rear muffler
- custom rear muffler

Behind the stainless pipes everything is 2mm mild steel.

This set up has moved stock peak power from 5,800rpm to 6,250rpm and the power curve is almost flat from 5,800rpm to 6,500rpm with a slight bump at 6,250rpm

Sounds nice too , this is still with the M60B30

[GazM3]

Nice to see u have sorted your cooling issues. In hot climates the ess kit without intercooling is a bit of a waste as the engine intake temp sensor pulls heaps of timing when hot killing about 1/2 the benifit of supercharging. Personally I would purchase the ess kit without injectors of chip then get the miller kit, then customise an Intercooler. You could use water/meth injection instead of an Intercooler as an option. I'm currently undertaking the upgrades mentioned along with a smaller dia pulley for slighly more boost. I'm just waiting for parts to arrive from USA as there are bits all over the place under the hood at the moment. The old owner thought it was a good idea to have chineese coils and all my knock sensor leads are buggerd. Best to start with the basics that are in good condition.

Did you modify your fuel supply ?

Fuel pump , supply and return lines ?

[GazM3]

Will prob upgrade the pump. The lines should be ok.

Better pump and it is good for near 600 from engine.

Great advice from someone actually producing that sort of power :-)

Is there a thread or write up on your 544 SC ? I keep seeing it on youtube but haven't found a write up on your car's specification

Now two pumps and bigger lines so nearby 750-800.

There is no write up, almoust everything is original parts except head gaskets and headers are made by me.

[dme88]

Hi man! So you got a S/C kit at last!

Yeah, I've been running your old power dyne kit on a low milage e39 for two years until now, when the tensioner went bad. I'm less than a two hour drive from ESS headquarter, so I'm going there next week for a new one. Vortech is miles better than Powerdyne, but for these low boost application, it does not really matter. imho.

Really nice looking e34! Love those rims!

Well i finally get to check in here. Ess Kit on my 95' 540i/6.

It's already not enough and i'm looking for more. Debating between e85 or 93 with meth injection.

Does anyone know how much psi the smaller pulleys give roughly?
