Superchargers

[verde]

Work has been very quiet so iv been browsing the web and thinking ( dangerous as it is ) the plan is after a years experience of driving to m50 the car next winter. The browsing part comes in the form of superchargers....always loved and wanted one. Dont want to over power the car, Rotrex etc boost up to about 300 brake, what would happen if i took a mercedes kompressor and stuck it on?

Your insurance will be un-affordable

[Rtaylor2208]

If declared your insurance will be most likely 10 times the value of the car at least. Even for folk 30+ engine swaps and forced induction can make there insurance ridiculous.

Verde, my insurance quote for the M30 supercharged was £400

[verde]

Holy crap you have a blower on yours?! god it must move. Hmmm, insurance might be an issue though. Well...it WILL be. In theory could it be done, a merc kompressor, custom intercooler and a remap and itl run?

[steve_k]

euan, to fit & run a S/C is a lot more complex than simply bolting it on with an intercooler & a remap, you have to take into consideration (sp?) where you'll mount it, all the extra pipework, the intercooler size, how you'll run it (aftermarket/standalone ECU) pulley sizing etc etc, there's so many factor's to take in it can be a right ballache.

also IIRC there is the fact that to make a set BHP figure there is the parasitic drag of the charger i;e it need's a set amount of power to run it before you go for your desired BHP out put.

hav a look on amazon there was a book on there all about turbo's & S/C's & how to use them correctly,

another big factor is the cost, cheapest method would be the like's of an eaton M90 S/C from the mini cooper S,
thats before you go looking at the like's of rotrex,

also do you want a rootes or centrifugal (sp?) charger??

google is your friend

[verde]

I did study roots/centrifugal etc but that was ages ago...forgot about the mini blower. Ima go buy me a book

it's the best way, also you could do with talking to somone like geoffbob who's on here from time to time.

No, no supercharger as of yet, but that's the way the build is heading atm.
Do you have a 318????
If so, lookk for "Appletree" on here , he has a supercharger set up on his M40.

I look forward to seeing it rav. Na man i have a 320. it wont be charged. The M50 thats going in it next winter will be. I want atleast a years driving under my belt first before i go bolting snails and big lumps to it

[verde]

Pass your driven test Verde and if you still have a licence after a year then think about it.

Thats what I said in the OP. Itl be next winter/spring. I just like to study my options so when the time comes il know what to do.

[Rav335uk]

The only M20 supercharged car on here is "Kingcruzier"

[maggspower]

A good book to read on this is called "Supercharged" (I'm going from memory here).

The author is Corkie Bell, his real name i believe

It covers everything, it is considered "the" book to read when supercharging.

I think there have been others though using eaton stuff. I'm sure this chap was on here.

Crazy noise.

I wouldnt waste my time touching the m20. M50, ITBs, 6 branch and supercharger would be the dream

[steve_k]

didn't gadgit have a S/C 2.7 m20? i'm sure thats what his brother steve told me a few years ago

[verde]

Found mini S/Cs for 400 pounds, but wouldnt an m50 rip the shit out of it? Or would it actually provide boost?

[steve_k]

euan, whats wrong with something like a 2.8 m20 on ITB's? thats what i'm planning in the next year or so

[verde]

Chance james is binning his m50 for a 52 so il buy his 50 you see.

fair enough, but you still can't beat the sound of an m20b28 on ITB's & a decent 6 branch but each to their own

[verde]

Got a vid? When it comes to engineering this whole idea of building a 2.8 m20 is not one i favour, i couldnt do that in a month of sundays

not planning on doing it till sometime next year but from all the threads i've read incl hairyscreech's thread it seems pretty straight forward.

[verde]

hairyscreaches thread set my brain on fire 2 pages in

And I said "if you still have it"

Im a sensible driver but then again, i think e30s bring out the bad side in people haha, the side that says " going into that side road broadside is the best thing to do right now "

here you go dude an m20 stroker on ITB's

[Kedge]

Verde, I think you'll find the M50 plenty quick enough for the first few years of driving. I think tyring to insure that will will knock any FI mods on the head. An M20 swap might be more friendly on the insurance side though being an E30 engine, either way it's going to cost you more to insure than the car is worth.

If so, lookk for "Appletree" on here , he has a supercharger set up on his M40.

That's an M42, there's even less sickos that fettle M40s

You need to look at compressor maps to find one suitable for your engine.

But a mini one will not be suitable at all. A Mini is what, a 1.6? M50 is a 2.5. You will need a S/C off a similar sized engine for it to work.

Yeah I did some research. If I do itl just save up for a rotrex. Wont be for aaaaages

Verde the new Imy?

[Cloggy Saint]

Verde the new Imy?

Reading my mind!

[BATTS91]

Turbo m50 is the way forward but the thing is , the price of doing a 300hp supercharged would surely be the same as 500bhp m50?

[Grrrmachine]

Verde the new stevie?
