So a lot of people have emailed me and PM’D me about why I switched.
The simpliest answer I could give was why not ?
I had the Bolt On Eaton blower on my car for 2+ years with no problems but to be honest it was getting a little bit on the boring side. I thought it was time for a chance and a good one at that. I was also curious to see the differences that each kit hold.
Since I beleive I’m the only one to have both SC’s on the 2.4 LD9 motor I’ll try and explain the differences.
The biggest difference right off the bat is the boost at low RPM’s. The GM kit starts producing boost at around 3,000 RPM’S while the RSM kit doesn’t until around 5,000 RPM’S. While the GM kit max’s out at around 4-5 PSI the RSM kit delivers alomst 6.
With the stock pulley on the Eaton Blower I usually saw almost 4-5 LBS of boost. Depending on the weather and where I was driving. Let me tell you on those hot muggy days the Eaton Blower was heat soaked with in 10 minutes and it was really hard to get it to cool off.
When I was drinving home yesterday I decided to beat on the car alittle bit. This was really the first time I had since the RSM Vortech SC was installed. I was also chasing an Audi TT at the time. LOL
I must say around 5,000 RPM’S it started to pull like no other. Something that it didnt do with the Eaton Blower.
I looked at my Autometer boost gauge and to a surpirse it was just shy of 6 PSI. Impressive I must say.
Just from the feeling I get the RSM kit delivers a lot more torque than the Gm Kit. The only reason I say this is from the way the car felt at those high RPM levels. It never felt like that with the GM kit although I was seeing almost 2 PSI more at those RPM levels.
The biggest advantage to the RSM kit is the troubled heat soak of the GM Eaton Blower. I don’t think there is any way around it without running a shot of Nitrous or going Alcohol injection which can be costly $$$ wise.
After I got home yesterday from driving the car for more than an hour I poped the hood and my vortech SC was cool to the touch. Try and do that with the Eaton Blower and I’ll meet you at the Emergency room at the hospital.
So inthe end I’m happy with my RSM Stage 1 SC kit and I’m preparin to run it at the 7th annual JCO bash on June 11.
Only time will tell what happens.
This car may not deliver a good 1/4 time down the strip but it will rape you onthe street or highway.
And again on an autocross course I’m sure the Vortech has the advantage.
The only reason I say this is from all the traction issues I predict I will have. LOL
That’s it.
Thanks Craig Lewis at RSM Racing for all your hard work in getting this car to where I want it.
This isn’t bashing one kit on another its an honest opinion to 2 different types of SC’s for the 2.4 LD9 motor.
Can anyone else honestly say they have owned both ?

thank you very much for posting your opinions on both. I've had a few people talking about it in my club trying to decide where to go. I have linked them here and hoepfully your wise words will help them decide. BTW do you have a picture from the top of the motor so I can see more of the enginebay install?
Asta La Vista OHV!! Defined Parts
awesome. i'm also glad to see that your response didn't blow away the gm s/c like if it was nothing.

Awsome post!!
I had my eyes set on a subercharger, but then i found
http://cavalierextreme.com/ that has nice kits for turbos. So what way would a person want to go when choosing extra power like this?
Nice review.. Maybe alot of people will take heed to this review and settle their thoughts on the 2 chargers.

Thanks for compliments Chris.
Actually around 4500 to 5000 RPMS.
Your Turbo kit looks amazing as I know that was your goal from the start.
I'm sure you'll work the bugs out.
I've love to intercool but its not in the budget right now.
More points at shows, I hope so as it sure does look purdy.
The ECOnator (Encriptor): I don't have any shots but will take some tonight.
Thanks to everyone else. This post is meant to be a comparison for anyone looking for forced induction and who doesn't want to go the route of a turbo.

That would be me my friend, Ive had RSM in mind for a long time now.

Nice review. Good to hear. I still like the GM charger the best.

Take the SC off, get the powder coat removed from it and it should drop temps a little . . . .
I am in the wrong career!!!
I wish I had that money to spend on two S/Cs and compare them.
Both are very good. You gotta love the intercooling of RSM's. You gotta love the price & simplicity of GM's S/C. In the end both are excellent product.
The RSMs will out shine in the road course's straits with its high top-end boost, while the GM's will be excellent in the mid-exit corner entries, where GM 's S/C gives mid-high rpm boost.
One good thing I would like to add.
Being RSM's boost at in the higher tach, that is very good for FWD cars. Having to much low-end all you do is break the front tires loose. Which I have noticed this in my GMPP charger. Granted around town GM's kit will be good for scooting through traffic as you don't have to rev the car to much to get really get going.
Both do get the job done. The question is; where would you like the power boost?

thanks for the review.That is the 100% truth. GM s/c isnt a HIgher rpm power adder like a RSM unit.(well depends what mods u have done/cams).
I couldnt have said it better myself. But i havent owned but one s/c (gm). I like though we have some options to choose from for boost for the 2.4l motor.
Keep us updated on the reliablity in two years to come with the RSM set up. I hope it is problem free( like put it on the car and not monkey with it) for 2 years.
Also, did u keep the GM s/c reflash and run the RSM blower? or u go with the RSM program?
i still like both s/c's always have
1 of these days i plan on having both
3000rpm would better suit me.
Good review.

RSM reflashed my ECU with their program. Its a little more sophisticated than the program GM uses.
As far as reliablility goes there is no doubt that this kit will be low-mainitance.
That and i have now joined the official angry squirrel club.
I'm very lucky to have tryed both SC's and am thankful for that.
are you still using the GM s/c injectors and map ? or did you go back to stock ?
also was the gm s/c program in the computer when you sent it to them ??
[quote=97cavie24ls(JDM cav sedan™)]are you still using the GM s/c injectors and map ? or did you go back to stock ?

I'm actually still using the 2 Bar map that came with the GM Blower.
I'd still like to try the regular map but from what I was told there is no real difference.
The injectors were replaced.
RSM installed the kit and re-flashed the ECU after the install.
The GM code for the blower was inthere at that time.
I want the RSM one so bad....but i dont live anywhere close to the places theyinstall it. =[

karo told me when i was cali a couple weekends ago , that some one did it and it helped out quit a bit
im not sure who though
only down side is no protection for the raw aluminum , atleast the way i see it
What if you striped the charger and then hot jet coated it?

You want to get the heat out... not keep it in.
With a header and exhaust system, you want to keep the heat in to keep the flow up and prevent the heat from transferring to other things where you really don't want it.
With this, a coating will not help you since it's soaking up heat from it's connection to the block. Eliot has been speculating into whether some insulator can be fit between the blower and the block, which would keep the heat from transferring so easily. Other than that, the only real solution is to either hit it with a coolant such as nitrous or alcohol, or draw the heat out somehow with some fans, heat sinks, etc. This is where the removal of the powdercoat would come into play. The powdercoat is likely acting similar to a hotjet coat on a header. It's keeping the heat in rather than allowing it to escape.
