Ok so i'm looking into going the SC route,

sold off my turbo kit, never got a chance to install it,
but I learned a good ammount about what needs to be done.

So i'm just wondering, what do you do about fuel/tuning with a supercharger,
is it the same as if you were running a turbo? I know the things they do are very close.
But does the JRSC kit come with all the fuel management you'll need?
or should it be upgraded?

I've got a socketed ecu, and could easily pick up some bigger injectors and have a better program burned.. just want to hear what you guys think.

thanks!

 

I would have kept the turbo.

But anyway, the kit should come with an FMU, but not a fuel pump. But since you have a socketed ECU, you could run Uberdata for next to nothing. Just get a fuel pump, and a burner if you want to tune it yourself.

Ok, so it just comes with an fmu, good info.
What about the rating on the fmu? anyone know that? like 12:1 10:1 ,etc.
have people running this kit found the included fmu to be sufficient,
or in the name of reliability would uberdata really be needed?
ALSO if I went the uberdata route could I use my stock injectors?

About the turbo thing....
yeah, I didnt sell the turbo with a sc in mind,
I sold it to help pay for my car.

Was thinking maybe i'll go turbo later on down the line, do a high quality kit,
but i'm thinking that SC actually fits better with my idea of how I want my car.
I like the simplicity of it, I like the fact that its belt driven, it seems more like an actual part of the motor, it'll weigh less, engine bay wont be as cluttered, power will be throughout the powerband, and its still fairly inexpensive....

The power I want from the motor would be what the sc gives me also.
I know turbo is the way to go for ultimate power, but thats not really what I'm after.

1) A turbo is equivalent in simplicity if not simpler.
2) Belt driven = power loss.
3) Refer to that link for the powerband issue.

As far as the FMU, Im unsure of the rate, but it will work with the stock 6psi pulley ofcourse. I had one on my car for awhile but realized we could not adjust it when I went for tuning. It gets the job done, and really is reliable, aside from harming your injectors after years of use. If you went Uberdata you would have to use larger injectors, such as DSM 450's, which would only be 50 bucks. I would really go Uberdata, it would be about the same price as an FMU setup, and cheaper than the AFC hack, and will blow both out of the water.

 

JRSC's come with a 5 to 1 disc.

thanks, good info.
hadnt thought about the belt drivin aspect as pulling power from the engine..
but that might explain alot of the power loss as opposed to a similar psi turbo setup.

That and they are not intercooled, an average blower loses efficiency after 10psi.

Just keep thinking about your decision to go SC. I had a blower on my GSR, and hated the thing with a passion, it was the most unreliable thing ever, however I did have one on an LS, and it ran like stock (but faster ofcourse), but now I have a 600 dollar junkyard turbo kit on my CRX and it just as reliable as the LS, so I have no doubt a Drag kit, or equivalent, would be just as reliable if installed and tuned correctly.

yeah i'm still thinking,
if I dont go sc i might just not go anything tho.
were you running a vortech kit on the gsr ?
ive done a good ammount of reading, and everyone raves about their jrsc, as far as reliability, ease of installation, and smooth power delivery.
but yes, they also complain that they want more power and often go turbo.
thing is, i dont really have that mentality, I like controllable power.
I dont want my wheels spinning out of control at the start of every gear,
or holding onto the steering wheel for dear life due to the torque steer.
about 140-160whp would be JUST fine for me!

let me put it this way,
I'm more interested in autoX and road racing than I am drag racing

oh and if its efficient up to 10psi, thats fine, as i'd probly only go as far as 8psi.

 

No, the GSR had a JRSC. A turbo setup isnt going to light up your wheels at a blip of the throttle, nor make it undriveable due to torque steer. Your not going to be redlining from stop light to stop light, but when you do lay into it, your going to get some torque steer no matter how you make your power.

What engine are you working with? You should be able to make 140-160 N/A. My GSR made 210 whp.

 

its a d15b, 128hp

 

Check out homemadeturbo.com. You could piece together a turbo kit for under a grand and have a really nice setup. I think you would be much happier with the end result, especially considering the price difference of the two.
