Supercharger or Tubo????
 

Hey Super Freaks,

I have a question supercharger or tubo i have a t3 and a old magnaflow root style supercharger MC60,

I am going to fuel inject the engine what would be better and why?:screwy:

I have no headers for either so i can go any way.

thaks again Super Freaks,

Cookie

Wow boost
 

Hi, for me its concelment, and response time. the Supercharger will respond much faster, but you will have concelment issues. Both will need to address, how much boost. With a turbo, a intercooler can be added, with some degree of modding. O I forgot to ask, what's it going in?

turbo is my pick.
More efficient, robs no hp to drive and if sized properly has minimal lag

I'm with Bry...^^^^:D

Hey,

thanks for the input the turbo woulld be easer to hide and the headers keep it under the deck so i think i will go that way.

the turbo is a t3 and it is going on a type 1 1914 turbo prept engine with a lowbudget.com turbo cam with makes all it,s power in low reves (riceburner killer).:woohoo:
thanks again,
to all the Super Freaks.

If you decide to sell the MagnaCharger send me a p.m. Although shipping charges from down there would probably be hideous to Canada.

I had a look at supercharging a Bug but unless you could get the ultra short Toyota 'chargers space was a real problem. the MC 45 is the most appropriate size for a bug engine up to say 2.5ltrs but the entry is on the end and therefore makes it too long in normal configuration. The advantage of the 'charger is that it makes power from idle thus giving the impression of a larger motor, whereas a turbo relies more on revs and tends to make its hp further up the rev range (a bit like a tuned motor). For a pure street car the mechanical supercharger has more going for it IMO but a turbo can make more ultimate hp.
In a bug the conclusion I came to was that a supercharger was the way to go as a first stage if the space problem could be solved. I have been recently been looking at mounting the 'charger at 90deg and taking the drive off a pair of bevel gears with the thing mounted on its edge with the outlet facing forward. This would then connect to a plenum with a feed to each bank of cylinders. The Merc CLK MC45 unit looks the best adaptable configuration and my next stage is to measure it all up and set it out.
There are more compact 'chargers like Vortech but they rely on revs to get the best out of them so the relatively slow revving bug is not suited.

I already have a Toyota SC12 unit off the 1.6L. I was thinking that the Magnacharger might be a better unit to go with, but from what you're saying it is probably too bulky. So I'll revert to my eventual plan of the SC12 plus Megasquirt ... for the distant future.

If my info is correct then the MP62 is for engines 2.0ltr - 4 ltrs, has a displacement of 1ltr/rev, all of which is a bit big but the architecture of it is that it is 10" - 17" long with an end entry that will require another 4". All in all too long for a londitudinal application (with an upright fan)

Hi

A friend of mine in Australia did a SC12 fitment on his bug, you can read about it here http://forums.aussieveedubbers.com/v...5678#pid711083

I'm not sure if he's on these forums.

I think he pops in now and again. I had a long forum debate with Joel on his conversion that I must say fits very well but here in good 'ol UK the SC12 is slightly rarer than hen's teeth and in general we are stuck with the Eaton M45s on the BMW Minis and Mercs. The big advantage of the SC12s is that the inlet and outlet are on opposite sides of the main case that makes it a very short unit. On the down side, that configuration creates quite a bit of turbulence within the body so doesn't have the hp potential of the Eaton unit. But if you're after a strong streetable motor with an easy installation then the SC12 appears to have all the bases covered.

Steve, I had seen Joel's car when I was over on the SBO site. I already had the idea to maybe try the Toyota unit, then seeing his buildup confirmed for me that it could be done!!

Hi

Joel gone to the dark side now, hes fitting an EJ22.

Steve

So sad... :rolleyes:

Funny enough, the turbo's from subies make more hp on an aircooled engine :D

im here Steve :D
just not on much lately and the great crash of last year sent my post count back to zero for some reason :shocked:

yes that darkside was just too tempting
