    Hi guys,

    I think I would like to install a supercharger to my BMW. I have a few queries and concerns about the setup I'd like to address before I do indulge myself in such a kit.

    My car is a 1999 E46 328i, which has done 145,000 miles. It has a full BMW service history. Will the engine/transmission be up to taking that much more BHP (190 to 320!!). What precautions can I carry out to make sure the engine is in top notch condition before adding all this power? (I bought a Haynes manual yesterday and would be willing to do the work myself). Will the transmission also take that much power?

    Will I need to uprate the cooling system on the car? (bigger rad)

    The supercharger kit itself makes 8psi of boost... which is a hell of a lot for an unmodified, normally aspirated vehicle to take. The C/R of the cylinders are for normally aspirated operation. Will 8psi of boost not just cause the engine to pre detonate and destrey itself without lowering the compression ratio? The kit in question doesnt even have an intercooler.

    Will I not have to subsititue the existing sparkplugs for colder running ones?

    Is the stock fuel pump up to the job?

    If nothing has to be changed for reliable operation then BMW have really over engineered their car! None of the kit manufacturers mention any need for changing other components around.

    I 90% finished a Zetec Turbo Project and I had to change all of the above, and then some (the other parts are included in the kit however, such as larger injectors, ECU tuning etc).

    Last thing, I have found a few supercharger kits, most of which are on this website:

    http://www.ca-automotive.co.uk/produ...faWQ9Mzk=.html

    With a little more searching, I found another company, Active Autowerke, who also do supercharger kits:

    http://www.activeautowerke.com/viewp...x?id=Product16

    This kit offers an 8psi supercharger for half the price of the other kits, with less boost, on the previous website. Whats the catch?

    Thanks for your time

    Dan

    As to supercharging your car.

    My car is a 1999 E46 328i, which has done 145,000 miles. It has a full BMW service history. Will the engine/transmission be up to taking that much more BHP (190 to 320!!). What precautions can I carry out to make sure the engine is in top notch condition before adding all this power? (I bought a Haynes manual yesterday and would be willing to do the work myself). Will the transmission also take that much power?
    yes, it wil take it. BMW engines are very over engineered and can take a lot more than stock hp.
    The tranny should be ok as long as you dont do hard launches all day

    Will I need to uprate the cooling system on the car? (bigger rad)
    No, although a fluidyne radiator never hurts

    Will I not have to subsititue the existing sparkplugs for colder running ones?
    probably -see the kit manufacturer for info

    Is the stock fuel pump up to the job?
    I wuold upgrade it to a walbro, they may say it will be ok

    If nothing has to be changed for reliable operation then BMW have really over engineered their car! None of the kit manufacturers mention any need for changing other components around.
    They have over engineered it!
    A guy in the Us called ulysees ran his 328i turbo at 735 hp at the rear wheels (900 engine hp as most would quote) with only a head gasket to lower compression and ARP head studs. It ran 10.35 at 145mph in the 1/4 mile in this trim.


    I 90% finished a Zetec Turbo Project and I had to change all of the above, and then some (the other parts are included in the kit however, such as larger injectors, ECU tuning etc).
    Fords are fords!! nothing like as well engineered to be honest. and Ive had a mondeo zetec and it was a great car...for motorway lugging

    My advice is dont go near CA automotive. They basically resell the AA product at a high markup...

    With a little more searching, I found another company, Active Autowerke, who also do supercharger kits:
    AA are the people to go to. They are at the top of their game and Karl (the owner) really knows his BMWs.

    Bloody hell!!!!!! 735 hp at the rear wheels with a near enough stock engine. You're not kidding about the over engineering then are ya! This does take a load off my mind. does the fact it have loads of miles not matter? What things could I replace to ensure it will run fine (if i need to replace anything at all).

    Thanks alot for taking the time to answer all my questions Boostist!

    (Its an E46 328i btw)

    Oops!
    I misread it was a 323i for some reason!
    My eyes glaze over after editing about 50 titles per evening

    It depends what kit you buy...they will tell you what you need to replace.
    One 'weak link' is driveshafts. But these tend to only break at 400rwhp plus (550 engine hp) so yours should be ok.

    If you google the driveshaft shop
    they sell uprated beefy E36 driveshafts and propshaft.,

    Your car is a 1999 E36 right?
