would there be any benefits or downfalls with using a supercharger and getting rid of the turbo,i know there would be a fair amount of work involved getting it to fit,anybody know if its been done before just the supercharger on its own,i know the fiesta with the turbo and supercharger on it works quite well,

Stavros

If you use a centrigufgal one like a Rotrex the advantages will be massivley better traction due to the power and torque (torque will peak almost as high as power) rising in a freakily linear scale as rpm rises, so no massive spike of power that loses traction, not to mention the fact that power will be directly proportional to throttle position which means controlling wheelspin is quite easy.

Also instant throttle response and power at any revs of course.

Ive been in a 400bhp Pug 306 on skinny road tyres, and with an ATB diff it had no traction problems, drove like a dream, and also pulled over 160 at brunters (hit rev limiter in top), so yeah, they not bad.

ive spotted a few on ebay from the mini cooper s and just wondered what they would be like or would the cooper s item be no good,i just thought of the idea cause the turbo on my car snapped the main shaft yesterday so thought of the supercharger cause the engine is already lower compression

Stavros

M45s from a mini are good for about 230bhp tops, so, no.

Only reason id bother on an RST, considering the fab work involved, was if i was going serious power, like 300+

would they still be no good if the pulley was changed for a smaller 1 or is it more due to how much air they will flow

also my engine is just a standard bottom end with jamsport head,piper 285t2 cam,beige injectors running on ofac management with a superchips 195 chip so its not massive power anyway so the mini item might not be to bad

Stavros

like i said, they good for about 230bhp tops, and by that i mean at over the maximum reccomended supercharger rpm, ie with the smallest pulley anyone remotely sensible would dare to fit.

oh right ok fair enough,what about the corrado g60 supercharger would that be no good,ive spotted 1 of those aswell with an m45 conversion so i suppose that wouldnt be worth it either

Stavros

no idea mate, but either way, your gonna need to make and fit a supercharger crank pulley, tensioners, custom inlet and outlets (they a funny shape both ends), brackets to mount the charger, custom boost pipes, etc etc.

sounds like a lot of work when you already have a perfectly useable turbo setup there.

paul16v

The g-ladders from the g60's are gash lol, and thats speaking from experience

just thought about it cause of the price of getting another turbo and just thought of a supercharger option thats all

Stavros

Be much more expensive TBH mate, be cool, but a lot of effort and more money and not much gain.

yeh suppose but no lag and almost instant power,i might try it if i cud find 1 cheap enough but i see what you mean about the aggro with making parts up,i do like the sound of the superchargers aswell

what about an eaton m62 supercharger would that be any better that the m45

mrjenrst

i've wanted to build an 2.1zvh and use a massive turbo but use a charger to take care of the lag

Afaik it's possible.
But the cost's would be massive

Stavros

M62 is better if need more power than an M45 can give, yeah.

But at 200bhp spec or so you should have much in the way of lag anyhow.

Deffo would be nicer to drive and sound awesome with a charger, but to me anyhow the amount of work itd take seems too much to bother with.

i will have a think about it and see how i feel,i know it would be a lot of work so will have a good think about it

anybody else know of anything like this done before

Barry_GTi

Well that's a turn up for the books, I remember back in maybe 2003 when I was doing Rotrex 106/Saxos you said Centrifugal Chargers were crap....... I always knew if you had a go in one you would change your mind though so well done for admitting it!!!! I have no chance of convincing the Kiwis out here in NZ though, turbo's are the be all and end all......

For FWD they are MILES ahead of turbo, however if you have no traction issues a turbo can offer more midrange...........

Stavros

There ARE crap IMO at milder power, ive been in a few and mega unimpressed.

But at stupid power for a FWD they make total sense.
