Jackson Racing / General Supercharger Q's

[mikemjohnson]

If i were to somehow muster money for JRSC for the h22, how much can you tune it? I know turbos have 100000x the tuniability, but my real question is i know JRSC give you like 6-8psi out of the box, safe for internals for a while, but if you build your engine, can you create more boost from JRSC? if so, what are the ranges. Id hate to buy it, and a few years down the road have money to build my engine, and find out after all that money building it, i can only boost to 10 psi or something. thanks and i know its a basic stupid questions but :smashfreakB:

[mizlude]

well I know you can buy an upgraded pulley kit that will up the boost. Also I know with some s/c you can port them out buy making the openings a little larger, im not sure if you can do it with them but I bet you can. Oh and roots blower love dry n2o ( wet kits with roots blower is a BIG no no ). I hope that helps bro.

[Drew]

one of the problems with the jrsc supercharger is they get very hot once you get over the 6-8psi. which can cause a lot of problems to include complete failure in the lubrications system. not only that, but heat soak will be a huge problem. of course a good way to counteract that is water/methanol injection. or if you can some how retrofit a intercooler to go between the supercharger and the lower portion of the intake manifold. i had an idea i had for an intercooler, by using the engine/superchargers suction to draw outside air through an intercooler that sits between the supercharger and intake manifold. then after that it would go into the supercharger to be boosted and then back through the intercooler to be cooled. but one flaw with that is as the air goes through the intercooler (before it gets to the supercharger) it will absorb a lot of heat and will make it harder to compress. soooo it probably wont work. but that leads you back to water/methanol injection. which will only cool the air going into the combustion chamber and not the supercharger..... so you're still left with that problem.

[94ludeguy]

i dont think there is a way to hook up an intercooler for the jrsc on the lude. there is just no room inbetween the engine and firewall. so the methanol is probly ur best bet. but i would turbo b.c it is easier imo.

[yogi_pahl]

what about the SC that are looks kinda like a turbo

[94ludeguy]

a centrifugal s.c it could possibly be done. but im not sure

[yogi_pahl]

y aone of thoes i think it could be done with the civic radiator mod and minus the ac

[00CDMLUDER]

they dont make a centrifugal s/c 4 the lude. u can upgrade the pully. i've seen ludes with 13 and one with 16 psi. you'd probably be better off just modding you engine and keep the boost low b/c of heat. u also cannot put a intercooler on the lude. u can exspect a maybe 20 more hp from a GOOD tuner.

[Drew]

yea your about right. with the stock pulley (which is actually closer to 8psi then 6) ive seen 220 hp to the wheels tuned. and usually 200 untuned. but there is a lot of variables to tuning... because most graphs i've seen have just I/H/E.. and usually a DC header at that. with a good header, custom exhaust, and a good intake.... i bet with a good tune you should easily reach 230+

[mikemjohnson]

ok so here goes the most asked question:
turbo or supercharge? but read my situation below before your opinion

heres my personal situation. ive decided to keep my lude for a while, and not sell. so, i want to boost, but DO NOT want to build the internals. which one will be able to last 2-4 years without blowing my already rebuilt engine with fully stock internals? im assuming either way ill be at 8psi or lower to not harm the engine, but which way should i go considering im not building the engine, and do not have the money to be constantly fixing the system (which i know can be a problem with turbos, constant maintance)
so what do ya'll think i should do in my situation?

[94ludeguy]

i think boost a 4banger imo. if u piece a turbo kit together it might be cheaper also

[twokexlv6coupe]

both turbo and super are considered boosting :wink:
and both of them will cost you around 3-4K for a GOOD, RELIABLE setup.

true i was just typin fast, :smashfreakB:

[yogi_pahl]

.02 would be with the s/c i place on getting one when i got money just b/c less maintance and more have turbos in them so its a lil more original

[00CDMLUDER]

i would go s/c (biased? maybe!) you'll have less hp than turbo but it would be safer on you stock internals and a lot less maintance. personally i wouldn't piece together a cheap turbo kit. if you want your engine to last longer i say get a s/c. either way you go u r gonna have to get that sucker TUNED! for any boosted car tuning is what makes it last most of the time.

[yogi_pahl]

not to get 00CDMLUDER ego any bigger then it is do what he says he right about his S@#T

[mikemjohnson]

00CDM you're supercharged? jackson racing?

im honeslty trying to find a used JRSC if i go that route

[twokexlv6coupe]

if you dont mind sharing it, could you post how much your entire setup cost?
so we could get a cost/power ratio to help people decide if they want a turbo or super.

if not thats cool.

[Drew]

and also what it cost to get it tuned

[1BadBB6]

i know this wasn't an option but why don't you dump the 3-4k you're gonna spend on the s/c into a good set of cams and head internals and a good I/H/E setup and a good ecu, say a tuned p28 or somethin like that. this would be way more reliable than a boosted set up plus be pretty close to the same numbers.

[00CDMLUDER]

you should get:
used JRSC -$1500?
p72 ECU swap-?
Hondata s200 with boost (Running @6psi - stock JRSC pulleys) $300
RC 550cc injectors $400
Ditch the JR FMU and use stock FPR.
Some good dyno air/fuel tuning. $150-250 per hr.
im not sure exactly how much my setup cost but it wasnt THAT much.

[yogi_pahl]

could u really builed an engine to run about the same as get ing a s/c and runing 5-6psi for about the sam price

[00CDMLUDER]

you could build a n/a motor to produce around the same hp but it'll prob cost more....and wont sound as cool. lol

[01BASELUDE]

I Have Heard A Major Difference Between Turbo An Sc Is When All That Power Is Available. With The Sc Its Instant Because Its Driven By The Belt, But Turbo You Have To Wait For It To Spool Before Power. Thats Just What I've Heard. Makes Me Want A Sc Because Our Cars Don't Have A Lot Of Tourqe. An Unfortunate Thing About Hondas But I Love Them

[00CDMLUDER]

well with the s/c you only boost when u want to. i can drive all day long and never go into boost if i dont want to but with a turbo u have to boost.

[charpy2os]

I dont really understand what you mean 00cdmluder, you can manually just turn your boost down, i thought you had to leave your settings the way they are after you get your car tuned? Are you saying you can turn the boost up and down whenever you want?
confused?!

[Mat]

Thats a good question charpy. Im lost as well. Are talking about your method of driving, or can you change you boost settings on the fly???

[92preludeSi]

put both on it :D

[twokexlv6coupe]

lies.
if anything, the OPPOSITE is true!!
now i'm not a total know-it-all when it comes to superchargers, but i would think since SC's are belt-driven DIRECTLY from the engine, they are always spinning (not always creating boost, but still spinning regardless).

with turbo's, the exhaust gases have to reach a fast enough velocity to START spinning the impellers (which doesn't come until XXXrpm, depending on turbo sizes, but could be anywhere from 2-6000rpm), which as we all know is called "turbo lag", which can be very beneficial if you want to save gas and stay outta boost.

yes the belt is always spinning but doesn't always create boost. but when u want it its instant. i guess with either a s/c or turbo u dont HAVE to hit boost all the time.

[crossfire]

I was reading about JRSC a found this:


There is also an integral bypass system in the unit that cuts off boost when it's not needed (high manifold vacuum, idle or cruise)

what does that mean?

[thermostate82]

i had a gtp and it was setup to only boost when I gave it alittle gas to go fast. if not then it would just run with out the boost.

[sirAIG]

I was reading about JRSC a found this:



what does that mean?

Can anyone follow up on this? Trying to learn more about these induction methods.

Thanks!

[98vtec]

its allows boost pressure to vent to the atmosphere when opened. Kind of like a wastegate.
