TURBO VS BLOWER

Post by **OVERKILL ENG** » Fri Apr 02, 2004 11:16 pm

Just curious as to what people would prefer either a turbo or blower kit for there Sierra.

Personally I'd prefer a bigger engine than either.... still beggers can't be choosers I suppose.

I guess it depends on whether or not they have A/c and P/s... makes a supercharger fitment much harder for space.

A small Eaton M45 would be good. power straight off idle. With injection of course.

Supercharger, its gotta be better for the low speed work wehere the turbo engine heats up

Wot he said, although thinkin 'bout it I'm pretty happy with the power outa the 1600

there are two suzuki mudracers that i have seen race against each other
1 is powered by a radical holden 253 with the exhausts exiting straight thru the bonnet and the other is a 1300 supercharged and i have seen the blown 1300 kickass at several meetings.

The bonus with superchargers is you have power from ldle and a turbo needs a load to buildup boost.

Yes a 4wd situation is the only place a supercharger is better than a turbo. On the road or a race track the Turbo is miles ahead.

I had a belt-driven supercharger a few years ago (about the size of an alternator), and i think it was off a subuaru or something. Anyway, i never went forward with putting it into the 1.0L LWB i had, so i resold it, but at that time, it looked like it would be very simple to install.

I've never been in or seen a s'charged 1.3L, so i don't know what they run like, but i do know that the turbo in my current lwb is awesome.

Does anyone know what the difference feels like between the 2?

But if you pick the right turbo with the correct efficency range for your engine then you will have boost off idle too

Post by **xtreem** » Sat Apr 03, 2004 7:54 am

OOZUK you can get the turbo working pretty good if it is sized properly but you will never get it boosting as early or as smooth as a roots (positive displacement) style blower.

MTZOOK. I have never seen a super charger as small as a alternater but it was probably a small powerdyne supercharger which are not positive displacement units and are a centrifigal design, they are more like a belt driven turbo but not nearly as good, the boost comes on much later than the roots style and they have major issues with chewing out bearings if you run any decent boost.

Mt ZOOK I think I know the blower you are talking about as I have one now that we are making brackets up to fit to a ZOOK.Should have it on and running for easter.I was just asking the question to see if it is worth making kits or not.
The blower is off a Subaru.

Hey sam,
What model subaru is the blower off??

supercharger would be a lot less hassleand better at low rpm :armsup:

Post by **Bazooka** » Sat Apr 03, 2004 10:50 am

I agree a supercharger would be better off for low down idle torque.
A small turbo could also reliably be set up in the same way but wouldnt quite get the instant response of a supercharger.
A supercharger would probably cost a lot less to setup as a kit apposed to a turbo where you need a custom exhaust manifold making it quite expensive.

Ahh what the heck, just twincharge it. :finger:

Sam,

I realised straight away you were figuring out whether to make kits or not. When i got that small supercharger, i figured it would be easy to make it work, but just didn't know how well it would work.

I figure if you could get those to run pretty well, then it would be a quick, cheap and easy install for people to buy. Just mount in place of the A/C is what i was thinking at the time....

Let us know how it works out with the one you're working on.

P.S. Sold mine for $500. (i made money on the sale)

What's the deal with the Suzuki Cappucino? Were they blown and turbo'd?? How did they run whatever setup they had in the 900cc's or whatever it was??

Post by **xtreem** » Sat Apr 03, 2004 6:44 pm

No way would you mount it in place of the aircon.

Michael you are thinking of a Nissan March MA10 1 litre turbo and supercharged.

I would not bother with a supercharger I don't see the point. efi with series 3 rockhopper is more than enough for low range crawling and then on the open road, fire trails and mud the turbo is awsome. It does not get hot at all when it's just idling round.

Overkill,
I'd probably be keen for a supercharge upgrade for my 1300. As mines a stocker and i've been looking for something to give it some extra boot for a little less money then a 1600 replacement.

mtzook any more info on your turbo 1300 would be sweet as well

ps: i've had a supercharged roots style commodore and i used to love the power from idle

I seriously looked at the supercharger options - there's lots of source systems most commonly the 4AGZE and 1GGZE's but it you're non-EFI you'd proably be as well off doing a 1.6 EFI swap, both financially and for the power.

Any turbo without injection or at least LPG is gonna be a compromise anyway (although it is HEAPS cheaper to do it that way).

In my case I'd have to either convert to EFI, or obtain another suitable carby (eg Weber sidedraft) - my Vitara carby is not perfect anyway and isn't gonna work real well on a blowthrough arrangement. Either would easily double the cost of supercharger installation.

have a look thru greg's buildup and stuff, he's running the lil cap engine... turbo intercooled, got a feeling it was round 660cc's, but really have no idea bout size :roll:

660cc is correct, the reason it works is becuase the vehicles (both the cap & gregs car) are really light

I think the other reason it works is because it has a lot of gears, so you can drive slowly with enough revs to get onto boost :cool:

I'm the same as qten, I also drive a stock sierra and would love the extra power early that a supercharger would give.

What kind of price range would a supercharger cost?

Post by **kiwilux** » Mon Apr 05, 2004 9:48 pm

We run a Supercharged Rover V8 (3.5L) over the ditch (NZ),

Simple, Reliable, cheap, and HEAPS of power from down low

Supercharger: Toyota 4AGZE, a dime a dozen (cheap), overdriven to hell (1.5) (bigger cubic inches of the rover, 3.5L compared to 1.6L MR2)
Fuel: Dedicated LPG, second hand mixer equipment (cheap)
Throttle body: Japanese, Nissan, almost free from most wrekers (cheap)
Some bracketry required depending on mounting and pulleys
Some home made plumbing and your up and running.

The benefits of running LPG thru the blower (which gets hot from compressing the O2) is it cools the blower.

Note !! Pays to have a "blowoff"valve (homemade) inline to prevent "bad things" happening in the event of a backfire or overboosting.

Hope this helps...........

Id rather be blown than injected any day !!!
Mike

Think it is a great idea

Just a mild application @ 4 - 5 lbs boost or something which will let you go a decent speed for a good price, and can be tuned up by the individual later if they wish.

Would you incorporate efi also :?:

Much more expensive I realise but big benefits

It would need to come in well under the cost of say a vit conversion but that should be quite possible I'd think. A S/C injected 1.3 would go plenty fast for a zook :lol:

Keep us posted

Post by **stumped** » Tue Apr 06, 2004 10:27 am

efi and supercharger for less than a vit swap would be a very nice kit, i reckon i'd be keen for a bit of that action :armsup:

I was thinking the same thing... And i guess that the vitara swap is what this product would need to beat - either in power, or in price.
