Here is the reason I like my JRSC setup vs a turbo....
I am in Iraq and bored right now, so I figured I would write this. This is dedicated to those guys that jump into SC thread and say nothing more than "JRSC sucks!!" or "Turbo>Supercharger"
I have been looking at turbo dyno graphs a bit lately to see if I wanna swap out the LHT intercooled JRSC in my car out for a mild turbo setup. Now mind you this is my only car and I use it to commute, so I would not want scary amounts of power (turbo or supercharger) cause of rain, traffic, inclement weather, blah blah blah.... So, for me I have came to the conclusion that I do NOT want to get rid of my JRSC setup....and this is why: all the useable low end power and reliabilty(not saying that turbo setup cannot be reliable). If you look at my dyno graph from when I got tuned you can see my extra flat torque curve and the almost linear power band. No lag here folks...8 psi @ 2500 RPMs as soon as you smash it to the floor and about 10.5 psi @ redline This this the reason that the JRSC lives on...not the peak power. Having a turboed LS that makes almost stock power levels until 4500 and starts dying around 6500 RPM is not what I call fun. I would never put a turbo on an engine that makes power like that but some do and think that it is good. So here is the dyno:
Note the torque curve and powerband folks...very nice and good USEABLE power from down low to high.
OK....I am not a Turbo hater at all...really...I just think that there is a place in this world that the JRSC shines. That is in the over-all powerband. Now one day I will build a strictly racing only Honda/Acura. Guess what folks...it will not a have a supercharger...cause they are limited in their power levels. I will have a turbo car one day and it will have LOTS of power and need slicks for any kind of traction. Just think of these things the next time you say "JRSCs suck!!!"

Re: (Azn Kenny)
haha, youre on 10psi, and im on 9psi, wanna race??
not to hate, because that is a very nice powerband, but i make almost 110 more hp, and prolly 65lb/ft of torque more. Not trying to hate at all.

I think a true guage of dyno comparisons would be to calculate the area under the curves and compare them. So even though you may be peaking a hp/tq number higher than him, that does not necessarily mean you're faster.

A friend of mine has a GSR with JRSC and it is one of the most fun cars that I have driven. Power on demand (it may not be 400+ hp) that is there any time you want it. Just like the original poster, his vehicle is used as a daily commuter in Chicago year round and it's exactly what some people want/need.

How about we take both of them to the track and run them? I bet the car with 110 more hp wins (assuming similar chassis).
The way i've always looked at it was, how much power to i realistically need down low? Driving around town, i need less than 100 ft/lbs of torque. I don't road race or autocross, basically only drag race where my car the lowest sees 4k rpm. I would have no benefit from a JRSC over a Turbo as i don't need more than my car can produce n/a down low.
That's me though and everyone has different circumstances so there is no broad statement of what is better.

Re: (njn63)
you don't have to get a big turbo...my car also makes boost at 2500 rpm 10psi and by 3k I have 17psi, and I put down way more hp than you and almost 75ft.lbs of torque more. it hits those levels and hold till redline...I would have to say my powerband owns yours in every way...and that is why turbo still owns jrsc all day long everyday. There is no way a jrsc will perform like a properly sized turbo at all in any way.

That would most certainly be the best way to guage the cars ability, however what I mentioned was what I thought to be the best way to compare dyno charts in respect to a motors output.

yeah, let's race. lol. less boost on my car, and more power, and let alone a faster car. im not hating at all, because its all in the preference of the owner, im just basically trying to show the advantages of a turbo car compared to a supercharged. Plus you get cooler noises! haha

well, the amount of psi really isn't a fair comparison as it differs depending on turbo/blower.

they are cool if you want to go "kinda" fast........Turbo is more fun. Superchargers are cool if you only do light to light raceing

exactly why my sc6152e is better than a dinky little JRSC roots blower.

Re: (kyle h.)
thats not a bad setup but its really only gonna shine for auto-x. Even up here in maine there are plenty of hondas that would be faster in almost any situation. But i do understand that what you have is what some people want
