Jackson Racing Supercharger (JRSC) FAQ.

[MadLorEP3]

thinking about going this route also have a stock 07 k24a2
just need to read up on which SC to roll with or whether to fuck with turbo.
I would basically need to buy the street kit for the ep3, upgrade the injectors to 650 and get a 3.3 supercharger pulley, relocate the MAP sensor
so I can get the carb sticker and still have the race kit, correct?

for the k24 that I can either go with a
6.3 cp and 3.8" supercharger pulley = 14,100 rpm (or around 6.9psi)
6.3 cp 3.6" supercharger pulley = 14,900 rpm (or around 8.5psi)
6.3 cp 3.3" supercharger pulley = 16,300 rpm (or around 11.1psi)

Is the k24a2 cp the same size as the 2008-2010 accord cp?
But then again someone made the statement below:

I agree but a word of caution with the JRSC...Since it gets hotter the more boost you try to make, the psi levels drop due to the increased air temperature. There is a point where the heat from the charger is heating up the air so much that the smaller pulley, installed specifically to make more boost, is useless. Because of this, a 3.8" pulley is typically the smallest viable pulley you can run. A 3.7" is pushing it and usually seems to be used solely for race days.

So should I not go with a SC pulley less than 3.8?

Selling a full RSX spec JRSC with aftercooler and methanol injection if anyone is interested. Ill post up a thread detailing the goods. had to go with the RSX JRSC to fit the aftercooler core.

Can you tell me more about this. Im in the market for a SC, just not sure which one rotrex or jrsc?Just starting to read a little about them today. So what exactly does the aftercooler and methanol injection? Do I still use 91 high octane gas? I will have to mod the rsx jrsc to fit it onto my ep right? Can you post or pm me some pics. Why you selling? Whats the mileage on the JRSC how long do they usually last? tnx

The aftercooler is essentially a system comprised of two heat exchangers, a pump, a reservoir, and a coolant. One of the heat exchangers is mounted (welded) on a plate on the bottom of the RSX JRSC access plate. The other is mounted in front of the car much like an intercoolers heat exchanger. The hot JRSC air is cooled by the heat exchanger within the JRSC. The water flows constantly through the JRSC's heat exchanger, through the pump, and through the front mounted heat exchanger. This keeps the coolant nice and cool.

Methanol Injection is just like what it sounds. You have a trunk mounted reservoir, a pump, some lines, and an orifice (nozzle). You fill the trunk's reservoir with some methanol/water mix and shoot it directly into the intake. This allows for cooler intake temperatures and gains with tuning. Usually 20-40whp and 10-20wtq on SC'd A2s and K24s. I believe a membere here has a tuned A3 on methanol injection hovering at just a littler over 270 to the wheels.

Together they are good for about 50-70 hp on tuned A2s and K24 motors. Id expect close to 300-310 on a properly tuned A3 with good supporting mods.

So will I still be able to use just regular high octane gas? I think so but just making sure.
Who makes this meth injection kit and aftercooler or is it custom.
What does installation entail, any fabrication involved? Any cutting of bumper of radiator support etc?
what does your kit include,is it complete? whats the mileage on the sc?
what kind of numbers can i expect on a properly tuned k24a2?
how much you selling for?

your calculations are off a little bit. at 7700 rpms i am making 10.9psi even and i have a 6.3" crank pulley and a 3.8" blower pulley. if you decide to run any smaller of a pulley on the blower with a 6.3" crank pulley you risk running the chance of overspinning the blower and you do not want to do that as the clearance between the rotors spinning twice the engine speed is about .005" so there is barely any room for error. on a k24a2 the pulley setup i am running would net you some awesome numbers and be reliable. its all in the tune, yes the IAT's are going to skyrocket if you dont have a cooling system like an aftercooler or a methanol kit. id recommend running an aquamist kit over an aftercooler. it takes injector pulse width measurments, TPS and load measurments and injects with throttle, normal driving (if needed) and full throttle driving. they are very popular in the evo/sti community and a freind of mine has one, and it really works. comes with a gauge that shows exactly what the kit is doing and how much its injecting. if i had the money it would have been installed in my car. its around 500$, a lot cheaper than the aftercooler and a lot less complicated.

[PAPITUYO326]

Both are pretty neat setups. Meth Injection is more effective from a $/hp standpoint in the shortrun, but you do need to keep that tank filled. Tuning with an aftercooler is a good bit quicker than a methanol setup though and the overall setup is easy as pie. The only issue with the current crop of aftercoolers is that you CANNOT fit one on the EP3 JRSC manifold. You have to go to an RSX setup, which does require some homework. Not a huge deal, but something to think about. The best daily SC setup is a combo of both. I loved my SC'd K24/K20Z3. Just got too good of a deal on something else that I couldn't pass it up.

I wouldn't be too concerned about overspinning the Eaton Blower. There is quite a bit of margin on these things. It do however agree it is preferable to use add ons such as meth injection and the aftercooler vs. increasing compressor revs to achieve more than 10psi.

so your saying its better to get this aquamist rather than an aftercooler and that the aquamist works with the methanol injection kit or is the aquamist an expensive version of the methanol injection kit

it replaces the aftercooler all together. i would much rather run a quality kit like this over an after cooler, with an aftercooler, what happens if you get a core leak? all that water goes right into the engine while being pressurized from the blower. the aquamist kit has a fail safe in case of a failure of the pump or circuitry. i have the snow performance kit in mine and kpro is activating it like a nitrous kit, but if i had this kit, it would be functioning all the time, whenever the key is on. suppying the car with the meth as needed

Regular Gas
The aftercooler Kit is a part of a batch of custom units made by a few members on CRSX.
No fabrication other than simply mounting things.

I'll pm you info on the SC, this isn't the right avenue to sell stuff or talk details.

You can expect upwards of 330 whp on a properly tuned K24A2 with an aftercooler and some sort of Meth Injection.

How would you get a core leak from a fully enclosed, pressure tested vessel? Is the metal going to disintegrate? Remember it is FULLY enclosed in the manifold, welded to the access plate and away from any loose parts. The only way it could feasibly fail or rupture is if the blower burst from centrifugals and impacted the core. Highly unlikely. Both systems have their benefits. Aquamist is a VERY nice system, but it still has the main drawback of meth injection which is the need for refills.

Let's take a track day example:

Assume relatively mild rate of 10 GPH (most use 13+ on serious K setups) during full throttle operation. Lets say you are running on a road course that allows 50% full throttle on a fast lap. You race for about 1.5 hours on said track day

That's 7.5 gallons of meth/water mixture you have to run through. Even racing 45 mins is still over 3 gallons of meth. Sure you can refill during off time, but what about in between?

The aftercooler meanwhile is always working. Not knocking Meth injection because I too have a kit, but I would aftercool before I would meth inject. Much less maintenance.

yes the system would be cooled off as well as octane increased from the methanol. also injecting water/meth has a steamcleaning effect on engines, over time of use it slowly breaks down carbon deposits on the intake valve's and piston tops and leaves a clean engine.

how do radiators or heater cores leak? they are pressure tested and sealed units. suppose there is an airpocket in the weld on the aluminum that creates a weak point and over time the pressure built up in the manifold vs pressure in the core causes a leak? its all very possible and the thought of it made me lean to methanol more-so than the aftercooler. and the aquamist kit is simpler, you dont need to add a second condensor for the fluid, the pump in the fender well, a resevoir where ever there's room, then run all the lines. both kits have advantages and disadvanteges. you can make more power on the aquamist kit, as it doesnt impeed flow within the manifold, and the fact it cools the IAT's way down, and the methanol increases octane for increased timing and leaner AFR's. my IAT's with the meth kit activated on only a 10gph nozzle where mid 70's. now granted when my setup gets more advanced, as will my jetting, i will need to increase to about 14gph

[MadLorEP3]

Damn this is some technical shit thats is way above my big head with small brain.

So basically the jrsc needs to be cooled somehow. You can either cool it with:
1) an aftercooler kit + the methanol/water injection kit

OR

2) an aquamist kit which IS a type of methanol/water injection kit


what does GPH stand for? And where do you buy this water/methanol mixture?

[MadLorEP3]

finally made it over to the aquamist site

and it seems that there will be less work involved if i get this kit since its plug and play and comes with everything I need
pretty cheap as well, only $650 for the hsf3

now just gotta find jrsc
