Never seen one of these before, i know they had turbos for the 22re but never seen a supercharger.

that 22re looks bad a$$.

corax

ah hell. If I would have seen that 2 years ago, I might have left the 22RE in my truck . . . on second thought, nah, probably wouldn't have left it in anyway. Nice looking set up though, just what I'd expect from LC Engineering, I'd love to see it in an '85 Celica RWD

how would you even install that? wouldnt you have to alter the air/fuel mixture, also oil pressure, etc?

Texas_Ace

The ECU will take care of the A/F ratio and the oil pressure will be fine, it would be just like bolting on a TRD SC to a 3.4.

Though i don't know if you might need some fule mods with that too.

iamsuperbleeder

hey, it's only as much an another motor!

yeah, LCE's had these for a while; I was looking at them with my buddy the other day.

looks like it comes with a fuel rail and pump
Cast Aluminum Intake manifold
Camden Supercharger
10psi pulley with belt
Fuel Rail with required fittings
High Output Fuel Pump
Thermostat Housing
All necessary hardware for complete install
Full illustrated installation instructions

Texas_Ace

True, but for a complete SC setup $3k is not bad at all actually.

iamsuperbleeder

meh, true I suppose...

what the HP increase suppose to be?

Texas_Ace

LOL, not a clue, i would assume that on 10 psi about 50% would be about right.

norcalsvx

turbo would be the way to go for cheaper (homemade style turbo kit)

Who cares about the horsepower increase?
I want to know about the torque!

By the way, LC must be hurting... http://www.toyotacatalog.net/M1WebGe...F-31B2996C4B75 lists the kit at 3495 and the ebay listing is 2800.
That's like getting the intake assembly for almost free.

Sure would sound purty all spooled up. Yeah the old Celica body would be swweeet.

Well... scratch yer head all ye want. But torque is why the rock crawlers go for dual transfer cases and low gears.
Torque gets it moving... horsepower keeps it moving.

91Toyota

Yep

I've always wanted one of these...but whats better...a SC or a turbo? I'm assuming SC because it's always moving and doesn't kick in...I think thats right anyway. It would sounds sweet

Texas_Ace

It depends on what you want to do, for high-rpm HP a turbo will be far better.

But for low end power (aka the power you actually use) a Supercharger will work MUCH better.

A supercharger car will feel "peppier" for normal driving then a turbo car. now if you are racing then a turbo will usually be a better choice.

abecedarian

Roots type superchargers are crankshaft driven positive displacement pumps. That means that the amount of air increases linearly with engine RPMs.
Turbochargers are exhaust driven centrifugal pumps and the amount of air increases exponentially with the exhaust gas velocity.
Superchargers generally make power as soon as the throttle opens, and turbochargers need exhaust gasses to spin up so they require the engine to spin faster before they start making power- hence the phrase "turbo-lag".

Superchargers generally peter out at mid-range RPM's when compared to turbos, since the turbo can take advantage of the increased exhaust gas velocity and spin up even higher. Also, the higher air temps created by supercharges limit the amount of horsepower a given combination can make.

The trick setup would be a hybrid super/turbo charger setup where the supercharger was governed by a clutch that would disengage the supercharger once the turbocharger made more boost than the supercharger did.

Also, another downside of superchargers is that 'most' superchargers are connected directly to the intake plenum. That means it's difficult to incorporate an intercooler in the system and thus lower the intake charge temperature / increase the intake charge density. Paxton superchargers are remote mounted and operate much the same as a turbo and can use an inter(after)cooler.

can someone please explain to me why these superchargers for a 22r are so incredibly expensive?? If you are curious what i am talking about, research how much it would cost to put together a street blower setup for a big block chevy... It cost me less than a grand to completely rebuild my 22r, with the machine shop doing all the head work.

Texas_Ace

Actually that is not a bad price at all.

The reason you can blow a big block cheaper is that:

There are more of them and they are all pretty standard. So thus all the bugs have been worked out and they are not cheap to make. While these for the toyota are all really custom jobs that are sold. So they cost a lot more.
