say i had a b seris motor......in an eg hatch......i want some mad performance......looking at boost and blowers.....from any of ur expeirences what do u feel is a better route....turbos seem liek a lot more work and they are...and more $$$$$ and more hassle to get one working right..were as a blower seems to be almost a bolt on item....what sort of power will each put out...thanks

Supercharges take power to produce power, works on a belt as for turbo doesn't. Runs off of exaust fumes.

Quick_CX

i know how they work....i know mechanics..no worries there..i'm just wondering if any one has either of these and is wiling to tell me about how it going even PM me and tell me....just curisou about going down this road

NoSpleeny

I don't have one but I can tell you what I think... how's that.

Turbos would be more for you. Cuz our 1.5 to 1.8 liter engines are under powered already so why take more power to power it?

You'll probably end up losing lower end power but gaining upper end while with a turbo.. you'll keep your lower end and gain upper end.. what's the drawback...? Supercharger will kick in immediately because there's no supercharger lag.. but there's turbo lag.
So I say go turbo.. unless you drive a V8 Cadallic with tonnes of torque to spare.

Quick_CX

yeah i see what u mean....hummm....turbo sounds nice right now..i'll have to look into it..pricing and all that

imported_Hybridtheory

if i had the cash....... i would go for a supercharger

Quick_CX

supercharger seems less hassle....and better but whe u say it takes power to gain power ur meaning it takes botom end tourque to make top end HP????????explain please

NoSpleeny

Nope...

The supercharger is hooked up to your driveshaft.

So.. when you drive along.. your engine not only has to power the wheels to move your car, it also has to power the turbine in the supercharger.

So it's taking power AWAY from the wheels to power the supercharger. So.. you'll lose really low end torque because your engine needs that extra power to spin the supercharger... you can avoid this by high revving each time you start at a traffic light and change gears at a higher rpm.. perhaps 3500 each time rather than 2500 or something...

so with a super charger, you want to try and keep it away from the low revs because you have less power in the low revs... and in the high revs, you'll have a lot of power.

Quick_CX

but all in all i am gonna get crazy power out of it..i compety see what u guys are talking about so my tourque will be noticablky lower?....but once i rev up in to vtec range i'll be booting it

NoSpleeny

Lets just say.. it'll be enough to push you back into your seat harder than your current engine can.

Remember.. there are different kinds of superchargers out there. You can get a low pressure one or a high output one... higher ones use more gas (more air == more gas) but you get more power.

Also remember.. any forced induction lowers the life of your engine too cuz you're making it work that much harder.. so don't be expecting to crank 500000 km out of your engine. haha

LOwer end.. it won't be a lot lot lot less but it'll be enough that you'll notice it but it's at the really low rpms.. (say.. below 1500 rpm)... cuz super chargers are ALWAYS compressing air while turbos only start compressing air (depending on size) at higher rpms.. that's why they have turbo lag.
Unless of course you drive a 911 with Twin Turbos.. then you have bi-turbos.. one smaller and one bigger.. smaller one spins up really early (1500 rpm or so) giving you small but noticeable boost really early.. and the bigger one spinning up at 3000 or so.. giving you much more boost (remember.. the pressure is combined).. don't quote me on these rpm numbers.. I'm giving you an idea of what it's like.

imported_JookSingKid

your question is all flawed.

which B-series motor first?

and what are you using your car for?

imported_toyman29

SC - better for daily driver

Quick_CX

yeah gotcha...well b18c1 gsr...

Quick_CX

daily driven eg hatch...b18c1 swap....i am leaning more towards supercharger...thus far

NoSpleeny

Do superchargers have blow off valves?

imported_Slvr-Bullet

Yes, Vortech does.

If you think that a SC is a "straight bolt on" with no tuning or upgrades necessary, you're wrong.

NoSpleeny

You refer to QUick_cx right? I never said that. lol

imported_Slvr-Bullet

Just in general

donesixer

I've said it before... whoa man...
A supercharger will create power everywhere. I does take power to spin a super charger but you will be on boost by 1500rpm. It takes 40hp to drive it, but it produces 90hp. Means you're up 50hp. Very driveable, fairly low maintenance.
Yes, the superchargers on the market have blow-off vlaves.
Turbo is not connected to the crank like the supercharger. It takes a second or two for the turbo to reach it's efficient rpm.
Once it gets there, it won't heat the air like the supercharger. It is more efficient=more boost safely=moh powah...
Some of you guys should research a little more before you spew advice.

cosmic zx2

um...i could be wrong here.... but from what i can read... all you've done is reiterate what no spleeny has said .....and manage to tell Slvr-Bullet that he doesn't know about SCs and that they are low maintence
