  • questions anwered from Supercharging company

    I thought some of you may be intersted to read some of the questions I have recently had answered:

    (How much is the fitting cost for the supercharger? I have been looking at an ESS unit supplied and fitted by Simpsons in the UK.)

    I cannot know the fitting cost in UK. Our price was offered as a bolt on kit which will be sent to UK. You can install the 447 hp Supercharger kit in 3 or 4 days. Please ask a regular BMW shop in UK for installation. You do not need a tuning shop.

    (Also will any items of the S50 engine need to be strengthened??)

    The engine will stay standard and no changes will be made. S50b32 is a very very strong engine. Some of our mad customers make 550 hp on M Coupes with our turbo kits and their engines are standard.



    (I currently have the following items on my car, will I be able to retain any??)



    (Eisenmanns exhausts 76mm.) must be removed because Eisenmann or any other aftermarket exhaust producer aims at increasingthe power from 321 hp to 340 or a maximum of 350 hp. As we make 447 hp, your eisenmann exhaust will cause high back pressure and exhaust gas temperatures. These should be avoided with our performance exhaust system.



    (H&R Anti roll bars, Schnitzer suspension) Very good parts. They will stay.



    (Wieschers carbon front strut) Should be removed, it is not solid enough. You need our front tower brace to make the handle better.



    (Pipercross Viper Carbon Induction) Should be removed



    (I am also about to buy AP racing front 4 pot brake kit) Do not buy AP Racing. I had AP on my M3 but sold them because today STOP TECH offers the best brake systems. For your M Coupe we offer the following Stop Tech brake systems:


    Please feel free to offer your views on any of the above!

    the part I am keen to get opinions from is running 447 horses through a standard S50.

    The subframe will definitely need to be strengthened with that hike in power. It is not mentioned.

    As good as Stoptech are AP have brilliant reputation in the UK. Sounds like he is trying to sell you Stoptech.

    I have heard the same about Weischers but you have had 2 different strut braces now(?) so would have been able to tell the difference.

    I'm not so sure about the exhuast. i'm sure Eisenmann could tell you if their exhuast would be suitable.

    I think the weakness we percieve in the s50 engine is the vanos. It is reliable otherwise.

    Lee, are there no supercharged e36 m3 evo's on e36coupe.com?

          I was just talking about its general reliablity. :-)

          Think we need to find someone who has done it and get their opinion rather than the manufacturer.

            it does seem that all the parts he is commenting on he can supply!

            it would be good to get someone impartial,

            i like the BMW shop bit, i doubt they will be able to fit it! they have enough trouble with putting wheels on!

            What have racing dynamics said?

              the photos of their body stregnthening work looks awesome.

              I have been to Racing Technologies today and they are not so keen on me doing the supercharger but would love to put an M5 engine,gearbox,loom and ECU in for me

              also when I have commented on selling my car they have urged me to keep it because its condition, and put some money aside for a new engine if I have problems later down the line (100k+)

              they said an S54 engine would be an easy swap, certainly easier than the e39 M5

              still tempted by the whole supercharger idea though :!:

                the M5 engine would be much better than a supercharger!

                you can tune them to 500bhp too!

                  if the weight of the v8 dosnt mess the handleing up then go for the M5 lump.

                  What was the price of installation?

                      yes looks like a nice way to go

                      400(at least) horses in an MC!

                      would I need different suspension??

                      I reckon I would be changing the diff again

                        I bet the all alloy 4.9 V8 from the M5 is about the same weight, read in a mag last week that the all alloy BMW 5.0 V12 is only very slightly heavier than the iron blocked S50 / S54....

                          Lee,

                          I think you'd need fully adjustable suspension where you'd need to weigh each corner of the car and adjust the ride height to get 25% weight distribution on each wheel (accounting for you as the driver also). Alternatively, you could put a little ballast at the rear end to counterweight the increased engine weight if it proved to be heavier than the OEM engine.

                          As for the diff; you may need to go the opposite way and get one which has a ratio of less than 3.15:1.

                          I think you'll know which way to go after you've been on the Welsh Weekend and been able to compare you car in its present form to a few others in real world driving conditions on the twisties. You'll have to be sure that the handling is right before you considerably increase the power.
