TURBO vs. SUPERCHARGER
 

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.

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

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.

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

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

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

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.

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

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

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.

your question is all flawed.

which B-series motor first?

and what are you using your car for?

SC - better for daily driver

yeah gotcha...well b18c1 gsr...

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

Do superchargers have blow off valves?

Yes, Vortech does.

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

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

Just in general :thumbup:

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.

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

Turbochargers heat the air that is compressed. What are you talking about?? That's why there's intercoolers...

And I did say 1500 rpm did I not (for SC).

Turbochargers take a couple seconds for it to spin up.. that's correct. I did say that also above. That's why I said there was turbo lag.

I was JUST about to say that... I said the exact same thing he said... just earlier.

This thing is giving me a headache.

There are really only two main kits that we're talking about here. Vortech and JR. The JR is a positive displacement supercharger. Boost is available from 1 RPM to 10k. It doesn't take any time create boost. It's perfect for low rpm torque. You cannot have a working BOV with the JRSC and Eaton Blower. The Vortech is a centrifigal supercharger. It's like a turbo that's spun off the engine. It's main disadvantage is that it has a peak operating speed, like a turbo, but since it's attached to the engine, it can't vary it's speed like a turbo.

What you get, depends what you want. I would say turbo, but putting together a good turbo system takes much more work and knowledge, but the potential is much greater.

Sorry, I'll go crawl in a hole now...
I didn't read all of it. I just saw a dude say that the JR will take bottom end away because it took power to drive it. Had to say something-you know?
Crap...I'm in a bad mood today too...:banghead:

there there donesixer.... sucks being in a piss-poor mood :( Luckily, with this weather, it's hard to feel down. My parade got rained on today, but I'm still chillin :cool: :smoker:

no worries....
we all have bad days.... nothing a drink can't fix :D :cheers:

Yup, a scholar once said:
"Beer is the reason for, and solution to, all of life's problems"

i.e. Last night I had too much. And, I think one would be nice right now...

Dirtylude, how do you lke your turbo? What kind is it? I think that it is you that has the turbo equipped h22a am I correct?


I would go for a turbo since you can upgrade to bigger turbos to produce more power. I'm not sure if there is a bigger SC or if there is one size?

Jacob, SCs can be upgraded too... M30, M45, etc or Novi 10 Novi 20, etc... they have different families and different sizes as well... just that turbos are more efficient by design that I like turbos better.

i didn't mean SC are a direct bolt on at all..sorry if it came out that way...i understand the mechanics behind it....i'm just wondering the most applicable one, turbo or SC...what about power gains and cost differences between the two set ups...

This is in regards to a JRSC

Technically you can upgrade a SC but not as you mention it (M30, M45....) Those are diffrent sizes in respect to engines. An M45 Eaton blower will fit on to a D16 while an M62 will fit on to a B16. You cannot put an M45 on to a B16.

The only way to upgrade a SC is by the pulley. Either replace the one on the nose of the SC or at the crank, the crank being the more easier and more popular one to do.

I like my turbo just fine, but it took alot of work and $$$ to get it working the way it does. What do you mean what turbo is it? The turbo itself is a turbonetics, t3/t04b ballbearing, which is a little small for the amount of boost I'm running. I'd upgrade to a t3/60-1, but I wont be spending money on the Prelude for a while now.

dirty lude do u mind if i ask how much in total you have spent to get that turbo set-up running the way it is...is it intercooled?...

Ha! I'm not adding it up, that's for sure!

I'm sure it's in the $15k+ range. All I can say is, don't start off cheap; you'll only pay more in the end.

ohhh wow...15 g's....just for turbo set up...your car must be insane......i wish i had that cash

Don't mess with the DirtyLude... hehehe =)
