RMCR Installed First Vortech in Colorado, 631 RWHP @ 7.5 psi Boost
RMCR in Colorado Springs started the install yesterday of a Vortech
V-3si supercharger on Mtcwby's 2SS LS3. The car already has
ARH Long Tubes and 3" exhaust through high flow cats and Magnaflow
muffler and makes 396.73 HP and 398.33 lb ft TQ at the rear wheels.
My Camaro before.
The Front Bumper off.
Stripping down the engine.
Washer fluid reservoir removed.
Coolant reservoir removed.
Factory Damper off.
New ATI Damper.
Drilled damper and crank for dowel pin to keep from slipping.
ATI Damper and drive pulley installed.
Charge air cooler installed and painted black for that stealth look.
congrats, any idea on when it will hit the rollers
Power steering pump moved and first bracket going on.
Power steering bolted back on.
Next bracket installed.
Charger bolted up and last bracket plate.
Bolts and idlers installed.
Relocated outside air temp sensor.
Washer fluid bottle and bracket.
More duct work.
Duct work, blow off valve, and washer fluid bottle installed.
Charge cooler plumbed, installed hardware cloth (screen) to protect from bugs and debris. Also note the factory intake air duct(upper right of cooler)
has been cut out to improve air flow to filter.
It's going on the dyno as we speak.:popcorn:
i am digging the black intercooler for the sleeper/stealth look :w00t:
Nice work Mike!
540 rwhp on first pull but would only make 4.5 lbs. of boost (6000 ft. altitude sucks).
Putting a smaller pulley on to get the boost where it should be, and try again!!!
Hey, I grew up in Colorado Springs! What part of town is RMCR in?
This install only took about 12 hrs. not counting the tune. Should take less on the next Camaro.
Excellent kit, I'm glad Vortech took their time getting it to market. They got every detail perfect!!
Thanks Brian and the guys at Vortech!!
Intake air duct cut away for more air.
You really have to look to see the charge air cooler behind grille.
A look from wheel well.
Beautiful install, thanks Vortech and RMCR!!
Mike put on the smaller blower pulley, but the belt is now too long, he ordered one. Should be here around
8:30 AM tomorrow, then we'll see what kind of boost it makes. I'll let you all know.
looks good sir
We have been installing Vortechs for over 15 years and this by far is one of there best kits. Cant wait till we get the belt for the smaller pulley and break 600 RWHP on the roller tomorrow.
what a waste of money................just kidding. Extremly jealous!
Can't wait to see the results!!!!!!!!!!!
What octane gas is in the car?
So we finished with 631 RWHP SAE & 565 ft lb's. This was with 91 Octane gas and boost floating in the 7.5 to 8lb range.
This intercooler is the best air to air we have ever tested. A 1st thru 4th gear run on the street, intake air temps never went over 95 degrees and in the 4th gear under full throttle they started to come back down to ambient temp.
Here is the dyno graph of before in after. The dip is my tach lead cutting out on me on the S/C run.
Final summary and first impression of driving the car
Well, I just drove from Colorado Springs to Loveland, CO after getting done with the tune. THIS CAR IS JUST AWESOME!!! It was hard to see the road because my eyes were squinted from the huge smile on my face.
When I went in the passenger seat on Mark's final test drive, I couldn't believe
the power. The only way I can explain it is, have you ever been on a world class roller coaster?
You know when you reach the very top and start down the nearly vertical drop?
Well, the feeling in your stomach at that moment
is what it felt like when he went through 1st thru 4th gears, times ten!!!:confused0068:
Anyways, the first 60 miles was great, then when I started into Denver
the snow started to fall, during Friday evening rush hour, fun, fun. It took
over an hour to go fifteen miles through Denver. By the time I got to the north end of town,
there was about 4 inches of snow on the highway,
and about an inch on the hood of my car. But not to worry, I found out that this car is very
driveable with all that power. I never once felt out of control
even with the summer tires. Traction Control and Stabilitrac works great,
as well as the antilock brakes. The Vortech is very predictable, when
driving normally it acts just like it did before the install, but when you
get into the throttle it just starts setting you back in the seat. You better be ready to shift, because it goes from 4000 to 6000 rpm just like snapping your fingers. If you aren't paying attention, it will bounce off the rev limiter
in a heartbeat. Still trying to wipe the perma-grin off my face!!:D
Now when cruising at 70 mph in 6th gear I don't have to shift down to get
around someone. It actually makes 6th into a gear you can use all the time.
I'll be heading to Arizona next week, and I plan to hit the Test N Tune night
in Phoenix while I'm there. I'll see what it will do at 1000 ft altitude. I'll
only be using my street tires, so It probably will take some fancy driving to
get it launched. But it will be alot of fun trying!!
I'll post up some time slips on this thread when I get done.
Also stay tuned for a link to the You Tube video of my dyno runs when
they get posted.
Also, I want to say thanks to the guys at RMCR. Mark is an awesome tuner,
he's very good at what he does. He knew I would be taking it to lower altitudes, so he did a very safe tune. Had a straight line 11.5:1 AFR all the way through the rpm range. He said if he was to just tune it for Colorado, he would have got another 20 hp out of her and would have set it at 11.8:1 AFR.
The peak boost on the dyno run was 7.5 lbs. at 6200 rpm. Up until
5800 rpm's the boost never got over 6 to 6.5 lbs. So it is a very safe tune.
Should never have any issues with my engine. The blower even stayed cool enough to hold your hand on it, and not have to pull it away even after
the numerous dyno pulls.
Here's some final pics:
In front of RMCR
Not much warning of what's lurking inside!!
That's Mark McCallon the owner and tuner at RMCR. Nice work
Mark!!:party0038: Thanks again!
What does that car have for camshaft and exaust? Thanks
ARH long tubes, High flow cats, 3" exhaust, Magnaflow muffler.
Stock Cam, no engine mods.
