if given a choice between the two a turbo using a garrett 28 and intercooler or a supercharger using a intercooler, (which would be a easier fit less mucking around) which way would you tend to favor

with the turbo I have to get rid of my extractors and then add a whole heap of gear to the car but with the super charger I only have to bolt the charger and cooler onto it and both will give about the same power...

still unsure as to which way to go

 

Ever since i researched into Raptor's Supercharger, i am a huge fan of em for the lancer. His supercharger's do not include intercooler( i know your asking about super with cooler). His price for supply and fit i believe is good value for money. Im planing on driving down to Mackay, QLD next year to get one fitted. Supers also seem to require less maintenance. The advantage over turbos is they have extremely little or no lag. In your case a super wood be easier to fit, like you said, you wouldnt have to change your headers and what not, and if you choose to you dont have to get an intercooler for a supercharger, it would be more "bolt on". . So if i was given a choice, Supercharger all the way.

Another idea is if your rich and insane you could go both.

 

I'm assuming something like a centrifugal blower, otherwise you wouldn't be able to intercool it.

Turbos actually have the potential to produce much more power, because the energy used to drive the compressor is wasted energy anyway, not energy taken from the crank.

But, as you pointed out, turbos also cost more.

My advice is:

Street or circuit = super
Drag = turbo.

Finally, if you want to go over 8psi, go turbo.

 

I say for fwd the supercharger must be better because the boost is linear.....therefore the wheelspin prob could be more controlled, ie more controlled acceleration.......however I could be wrong...its happened before - well thats what people told me anyway!!

Centrifugal blowers don't have linear boost. They have engine RPM dependant boost.

 

yeah it is a centrufigle ( or what ever you call it )and I am led to believe that I could safely run 10psi with out a I/C so running with one I could go as high as 12 or even 15 psi but only for those special occassions )

I'm sorry I don't know what lnea boost is ....

 

Ok at 1000 rpm 1psi, 2000 rpm 2 psi, 3000 rpm 3psi etc so the more you give it the more boost you get, so rather than sitting at 3000 rpm and getting 12 psi you slowly work up to the power at higher rpms.....so you can launch at lower rpms and drive with the boost rather than fighting wheelspin at launch.

Jaime

 

That's the upside... The down side is, that if you want to plant it from 3000rpm, (or any other cruising speed) you might only be getting 30-40% of your max boost.

You do also realise that to change from 10 to 12 to 15 psi boost, you need to take a spanner to the engine and change the pulleys, don't you? Your "special occasion" could take you up to 2 hours to change and another 2 hours to change back.

 

Everything you say is true Sunder.......but for front wheel drive I'd still go the supercharger......however RWD or Awd for sure the turbo!!


Jaime

 

that does not bother me having to change pullies over and loading up the program ect as I would only be using the 15psi for drag days - but I was not aware that that was what was involved with changing boost
thanks for the heads up on it

 

If you get a S/C installed knowing that you are going to change pulleys for more/ less boost they can set it up to be a 20 min job....ie easy access to the drive pulley......Also Christine remember that you set the pulley for maximum boost so at your shift point is where you want maximum boost.......you dont need wheel spin as you change gears or take off so the amount of boost is lower then, and peaks at your shift point in direct relation to your RPM's. Also you can get the S/C installed so you can disengage it for just city cruising and NO lag at all (although very little boost at idle ; p).

Jaime

P.S Raptor is NOT employing me as a sales consultant.....although I wouldnt mind one of his kits if he's giving one away!!

 

Do a deal with him See if he'll like give you every 10th one for free or something - so if you feel you could sell 9 of them to friends/car club members, then keep the 10th one yourself.

 

thanks for that bit of info very interesting to read - I really don't know much about how they work ect but I am learning and the small amount that I do know is starting to make sense to me
