why does everyone hate the JRSC

turbo and swap i cannot smog... but jrsc is carb legal. wuts with the hate tho on the jrsc

I personally don't hate them.. I would just rather go turbo because i think there is more potential for making greater hp. Plus i like the sweet sound of a blow off valve.

There are turbo kits out there that are carb legal.

It's a lot of money.
Pain in the ass to install.
Not worth it.

wut carb legal turbo kits are there for a D16A6?? i thought the only carb legal FI kits were vortech, JR, and greddy?

**edit** i mean the only carb legal kits period are vortech, jr and greddy. but as far as i know the only kit made for the A6 is by JR

Damn... I must be trippin'. I swear I saw a carb legal kit for the d16a6. My eyes must have been decieving me. Sorry about that.

no there might be i wasnt trying to imply that there wasnt, i wasnt tryin to proove u wrong lol. only inquiring

Most people only know about them what they've read on the internet, thats probably the biggest problem with them. Turbos are more efficient too.

I lub the JRSC. For the cost, it makes good power (you wouldn't complain about it).

OH, the way they scream.. Its fuggin awesome. I'd take that sound over a BOV anyday.

well everyones got bov :[ like ive been all amped up about doin this project this summer cuz i got the money and everything im just tryin to plan it all out.. but i read online everywhere that ppl hate the jrsc.. one page even said he only hit 15.4 with it on a crx. maybe he only had an HF or somethin, but seems with a power/weight ratio that is better than my gsr will hit the same times...

Good answers! :thumbsdow

They run about the same price as a turbo kit.
They are ALOT easier to install, over a full turbo setup.
Not worth it? Why is that? Because YOU cannot afford to go with one?


Pound for pound, boost wise, the superchargers will not perform as well as a turbo. a 8psi turbo setup might yield 275hp, and a 8psi charger setup might yield 250hp.

Done right, a charger can be just as good as turbo.

Does anyone know the maximun about of boost A JRSC can put out? I know you can get different pullys.. but there has to be a limit.

i think with the kit for the d16 engine you can get a pulley to make the max psi around 11 psi for the JRSC. Any more would be a custom application (so i read anyway).

thats wut i read too. 8 psi stock, boost upgrade for 2 more psi but it costs like 500 freakin bucks. comes with ignition timing upgrade too thats why, not just pulleys.

So really... a JRSC has a limit of 11psi.. if you want any more power you have to go turbo(without doing a custom set up and spending thousands) Anyone disagree with that?

unfortunately i live in the one state that regulates what i can do to my motor :[ ive also heard jrsc runs hotter too. hard decision to make on my part :[

yeah... if it came down to either getting a JRSC or not getting anything at all.. Then i would just get one.

I feel you, california is a biotch about what you do to your engine. There is a huge list of what you can't do including certain swaps...and if you do swap you have to get it bar certified and all that. The JRSC is good, I would personally get it if it wasn't for the price.

i agree that the jrsc cost as much as a turbo. as the pain in the ass to install..............not really. its down right easy. just time consuming like a turbo install

[QUOTE]Most people only know about them what they've read on the internet, thats probably the biggest problem with them. Turbos are more efficient too.

yes, people only say what they hear. when i had my jrsc and turbo, the jrsc was my car to drive from point a to point b. the turbo definately makes more power, there is no doubt about that, but, i love driving the jrsc si. anyone who has experienced both, has to love that instant power. it is very limited on the top end though. in the end, i kept the jrsc si and sold the turbo hatch.

12 psi seems to be the limit on b series applications with the m62 blower. the problem with the roots charger is that it goes into the twilight zone (the point where boost efficiency = 0). that is very limiting. i boosted at 11 psi and the intake temps where crazy. i prefer the 9 psi and thats where it is now at.

thats wut i read too. 8 psi stock, boost upgrade for 2 more psi but it costs like 500 freakin bucks. comes with ignition timing upgrade too thats why, not just pulleys.

either way you go, why waste your time with hacks. they barely control the tip in detonation. waste of money. nowadays, there is hondata, aem, neptune, uberdata to go with that gives alot more control. back in the time, there was no choice, but, now there are better ways of doing things. its kinda like would you rather use a bow and arrow to kill a deer or use a rifle?

unfortunately i live in the one state that regulates what i can do to my motor :[ ive also heard jrsc runs hotter too. hard decision to make on my part :[
that is another problem with the jrsc, does not have an efficient cooling system. the only viable option would be to go with an expensive lht mod or use water injection to control tip in detonation. a good engine management with a good tune should take care of that for you though.

concerning the turbo vs sc debate. there are plenty of threads that cover it.

just afew of the reasons of why i'll never live in the golden state :p

[i am going to try to get my project going this summer and i want to try to put a supercharged b16 or b18c in it.I personally like super than turbo even though turbo has more potential

I was reading about the JRSC today on Hybrid page - I think you should read it before considering it.

http://tech.hybridgarage.com/tech/marc-jrsc-after.html

Just some food for thought - I probably doesn't happen to everybody, but kinda steered me away from them.

wow.i do not want that nightmare. i gues i will go NA and try to build a very strong motor.i want at least 200 to the wheels. i better start building. thank you for that info

damn that freakin hybrid link... :( ive got like no options now for FI

Also Im sure they fixed this problem but my friend (that later got a turbo) bought a Jackson supercharger when they first came out and it snaped the input shaft where the pulley bolts to broke his idler pulley and took out his water pump. But I have to say they refunded him his money, fixed all the broken parts and paid the shop (he worked at and did the install himself) almost $1000 in labor alone (where he got the money to get the turbo setup and his new swap).
So he likes them But would never install or sell another supercharger on a honda/acura again.

You can do what I did for around the cost of that supercharger you can get a D16Z6 and wire your car for OBD1 have it ref'd and buy a Greddy kit for $1460(kit price) shipped. Mine cost a little more cause I built up the z6 but it can be done for the cost of the thing.

old complaint.

if the blower was leaking, then it was jacksons fault. they should have replaced it. and they did, eventually, free of charge.

he whined about labor charges, his days off, how jackson did his timing wrong, detonation, not enough fuel, excessive fuel pressure.......blah,blah,blah.

my conclusions are.....................if you plan on doing modifications to your car, learn to do it yourself. it is the whinners who dont know what they are doing. if you dont know what the hell you are doing to your car, then, dont buy the product. he complained about fuel and timing, yet, he still went with an fmu, piggybacks, and hacks :lol2: what a funny guy.

his problem layed with jackson not fixing his blower and the service he didnt get. the rest is just blabber.

Kris, even if I could afford to go with one, I wouldn't waste my f*ckin' money. And yes I've read a substantial amount about them, including instances like Cjz89civic just described. Why deal with such hassle? Still not worth it for an A6 IMO...

I wanted to do one once (because it was bolt on) and did some research and red articles and stuff. I don't think I'll ever do one just because they don't have any potential. And if you do want to get any kind of serious boost out of it you have to tear it apart and redo the pulley and possibly even have it rebuilt to have the blower inside move more air (something like that, been a while since I read about them). Plus I personally don't like the idea of more belts, or one belt running everything - he he - if it breaks I'm screwed, and I'm sure it's not cheap either. One of the guys in my old car club had a newer prelude with the h22, dropped a super charger in it, and couldn't drive it reliably because the belt kept breaking. I know he broke at least 3-4 belts, possibly more in under a year. But there are just as many horror stories about turbos I'm sure. These are my personaly opinions of why I wouldn't do one, but if it meets your needs and will work for you and you are comfortable with it, then I wish you good luck and hope you get to tell us a "good story" about them.

Yep even if the turbo kit is cheaper, it comes with a FMU and most of the times no intercooler. The JR supercharger cost about $2,000 new off ebay for non/vtec and $2400 for vtec engines.

The thing about the JR kit, is you have everything you need and its already tuned so it basically "bolts on" and no tuning really required.

I believe 15psi is JR largest pulley, and using the b20 CRV crank pulley doesnt it put it up to like 18psi max??

Id take JR for the reliability of everything being there and almost any average person that can use tools, should be able to get it installed in a day or two.

the JRSC can go higher than 11psi...i know T.O.O ( www.theoldone.com ) at Endyn had it so that you could send in your JRSC and they would modify it for you so that you could make more boost and offer different pulleys ( http://www.theoldone.com/components/blower_pulleys/ )

but i don't hate on the JRSC...just expensive...i'd rather piece together a turbo kit...but that's just me...

its because the sohc kit runs on one belt, so if that belt breaks.... :uhoh: the dohc kit runs on two. you can break a belt and the car will still run. if the belts are adjusted properly (90lbs - 120lbs) or (1/4 inch - 1/2 inch deflection) the belts will be fine. the h22 guy broke his belt so much because he didnt know how to properly tension his belts.

the jr kit is not already pretuned. to be pretuned, it would need something to tune with. the jr kit only comes with a shitty 5:1 FMU. just like most other turbo kits out there. anything past 12psi just becomes a giant heat pump without cooling. installation should take about 8 hours. assuming you know what you are doing.

could you imagine how fast a supercharger would have to spin to make 18psi. Plus it would get so hot that i'm sure it would not be good.

intercooler and heat wrap should alleviate a lot of the heat...

ask T.O.O. if they have an intercooler available for JRSCs....they may seeing that one was going to be used for their SC set-up...

Q: How much boost does it make? Can my stock bottom end take it?
The boost is variable and it goes up to 24 psi with about 17 psi at around 3,000 rpm. Many prototypes have been up and running for more than two years with stock engines. It is not boost that kills the engine, it is bad tuning and detonation at the wrong place/time.


Q: Does it come with the intercooler?
Originally it was not planned because the blower efficiency was quite good as is... together with the well designed intake manifold even in Texas with 100+ degree weather the car has never detonated. However, due to new technologies that are just now available and also with this Summer 99 Texas weather being 120+ we decided to inorporate intercooling into all kits. Our IC will cool the air to well below ambient temperature, and the special "membrane" setup will not upset the air. In fact this is pretty much a zero loss system in terms of flow and there is zero pressure drop.

but everyone's bee waiting about 5 or so years for the release of their SC...but the prototype is on his 91 si...and it run's 11's

How do you run an intercooler on a SC??

How do you run an intercooler on a SC??

dunno :dunno: ...don't know how u put on a bov...but you can

theres some roots blowers that have oil or coolant passages in them to cool them off

ive seen air to water intercoolers in them as well. another setup i saw had an icebox built around the outside of the charger, with the pulley neck sticking out one side and the throttle body sticking out the other side. i imagine it works pretty well, but i think its not ideal for daily driving

but everyone's bee waiting about 5 or so years for the release of their SC...but the prototype is on his 91 si...and it run's 11's

wow, pretty impressive on an m62......actually, it is very impressive. where are the pix, setup, and dynos at?

current avaliable cooling methods for the jrsc is through lht or water injection.

my bad...he has an 89 civic si

for dyno #'s...u gotta search their site... www.theoldone.com

...the jr kit only comes with a shitty 5:1 FMU...

wut do u mean by 5:1 ?
