I just hope they use a unit that can be utilized at higher rpms. The Vortech unit would be on the verge of losing its warranty with an 8k rev limit and one size smaller pulley.

I've heard so many good things about the JRSC on the K20. Guys hitting nearly 500whp.

If the setup is well built and reliable I might pick one up. I really like the Vortech kit, but I still think 300whp needs to be attainable rather easily. And it doesn't look like the Vortech will hit that goal without E85 or too much boost imo.

My only gripe with the pics above, is it looks like they are using a pull-thru maf configuration. I do like the Vortech blow-thru setup better.

I've been out of the RSX scene for a while, but I only ever saw one guy break 400whp (it was around 425 I think) and he swapped his JRSC to a HUGE Lysholm unit and was pushing close to 20psi

I'm waiting to see what these guys come up with before I plunk down on either an S/C or a turbo. I just hope it happens fairly quickly!

New info from website! Pricing!

They don't have any info on HP/Torque, but they do have pricing up and appear to be taking deposits. I'm hopeful this system will prove more powerful than Innovate or Vortech.

Good eye.

$3695 without tuning. Deposit is non-refundable unless the SC hasn't shipped by 12/1.

No exact dyno numbers, but they did provide this:

At 9psi of boost pressure, the supercharger system produced an impressive +80whp on 91-octane through the OEM headers and exhaust, and +125whp on E85 through Skunk2 headers and exhaust.

Interesting bracket. I wish I could see more in the engine bay pic. It looks like they are using an oil cooler but you can't really see what brand it is or how the lines are run. It definitely looks cramped.

I wonder how this will stack up against the soon to be released Jackson Racing Rotrex kit.

Not even going to wait and see how it compares to the Jackson Racing kit when it releases any day now?

CajunFRS · 10-02-2013, 11:10 AM

The fit and finish of the JRSC will make it or break it for me. Should just bolt up not bending or cutting.

CajunFRS · 10-02-2013, 11:19 AM

Kit looks niceeee. I'm impressed.

xwd · 10-02-2013, 11:37 AM

The dyno plot is fairly impressive, but it would be nice to see some independent results.

xjohnx · 10-02-2013, 11:41 AM

How hot does that compressor get? Seems awful close to the oil filter.

Nothing is stopping someone from running 12miljillion RPM, and just run a bigger pully, but you will run into the same issue with this one. Say it's max rev is 70,000 and it develops 14 psi @max impeller speed. Well there's gonna be the people who find the pully that maxes it at 7400, then there's gonna be the turds that complain that they will lose their warranty if they run that pully with a 8k redline, kinda like what you just did...

I also believe vortech just realeased an upgrade path to a 65,000 max rpm from 53,000, for all those turds that had the 2.87 pully and wanted to raise there redline to 9k.

The 2.87 spun to 53k. Blower would only handle 50k... Just to make sure that was clear haha. Also it sounds like that dyno was on E85 as the post above says +125WHP on E85...

Although I did a quick photoshop overlay over a dyno of mine on E85 (i am running just a tad more boost than them) and the low end seems like it may be more promising.
