Which supercharger is better for the money? Which one creates greater HP/TQ numbers?

can the vcs or jrsc use a boost controller? Or do they both require changing pulleys?

wantboost

both require changing pullies.... just get a turbo.. more effiecnt, more power and more upgradeable down the road

Finger Lickin' good

its like apples and ornages...if you go vortech its like a turbo charger. the jackson is a completely different system.

It's a boost controller for JRSC, but this guy doesn't make anymore. You would have to find it used somewhere

Vortech= very little low end boost, high top end boost
JRSC= high low end boost

wantboost

jr - low end torque.. no upper end.
vortech - no low end, mostly upper since it doenst build full boost till redline

turbo - insane top end, quicker boost repsonse, etc etc

But isn't there a lot of work involved in turboing a non-turbo motor like changing some of the internals?

madhive

You would have to do the same for a supercharger.

so which is better...turbo or supercharger?? I was unaware that you had to do internal work for a supercharger.

If that were true everyone would run a Vortech YS-trim on their stock D-series motor and make 800 WHP. What the hell kind of a comment is that, I didn't think that you had to do internal work for blowers? If ANYTHING the blowers put more stress on the internals, it's not uncommon to snap the snout of a crankshaft off with a blower car, but so far I've never seen this happen with a turbo before.

madhive

If your running low hp levels (200 Dseries, 300Bseries) you don't need internals.
Go turbo if you want big numbers, Go super if don't want to go above 250.

i know this guy that blew his motor (ls/vtec) twice on jackson racing supercharger. the third time, he just went turbo. turbo puts a lil less stress on the motor since you dont have to boost all the time.

madhive

A supercharger doesn't boost all the time and a turbo puts the same amount of stress on a motor.

no, a turbo doesnt strain the motor as much... think about it, the motor has to physically use horsepower to turn the supercharge off of the crank, a turbo is powered by exhaust gasses from the combustion process

madhive

When the supercharger is not in use it requires only 1hp to move.

wantboost

iTrader: (2)

the supercharer is always turning.... it takes more than 1hp... more like 20

Yeah, all that belt tension that the blower puts on the crank pulley and therefore the CRANK does nothing to it or the front main bearings, right?

madhive

If thats try then a supercharged engine would never fall below 2000 rpm and you don't hear that happening.

wantboost

iTrader: (2)

huh... what the **** are you talking about... a supercharger is driven by the crank pulley directly... no clutch or anything, therefor if the motor is running the supercharger is spinning and the engine is having to use more energy to turn that supercharger

madhive

All I'm trying to say is when your just cruising or at idle it takes 1hp to keep the supercharger moving because it's not boosting. But once you give it full throttle thats when it needs 20 40 60 80 100hp to turn.

Sorry TurboEGhatch...i didn't know that everyone in the world was supposed to be schooled on forced induction systems.

both super and turbo chargers rob power from the engine. yea the supercharger uses power to turn the belts. but the turbo is just one hugh exhaust restriction. not to mention the load on the engine having to push all that air throught a big intercooler.

you have to sacrifice power to make power when its forced induction,

With Eaton blowers (JR), it only takes about 1 HP when not under boost. It is only under boost which robs power (power needed to pump and compress the air charge).

Depends on power level. You can boost all day long with a well tuned setup with appropriate power levels.
