Hello everyone.  I've gone crazy and got myself a Magnuson TVS 1900 Supercharger.  After a few days of figuring it out, I got the supercharger and components installed(since I'm mostly a "weekend" mechanic, it took me a while longer than 1 day!).  Anyway, I'm waiting on Magnuson to get the reprogrammed computer back.  Then I'll install it and see what happens.  Is there any advice from you seasoned "forced induction" guys (and gals?) that you'd like to give?
Let the "forced" fun begin!! :B:
 
Great job installing your Supercharger any pictures?

As far as advice, look all around twice before flooring it...
 
Considering a blower for my truck... How much did it cost you, how many PSI is it supposed to put out and any idea what the power added over stock is supposed to be?

And is this a Centrifugal or Roots style blower?
Centrifugal will mount like an alternator, roots style replaces the intake or goes under it as I understand.
 
Cost for me was just under $6,000.  Stock horsepower at the crank is about 320HP.  Torque at the crank on a stock 5.3L engine is supposed to be about 335 ft/lbs at the crank.
The boost is set for 6 psi from Magnuson. The additional horsepower, at the crank is about 100 to 120 horsepower, so over 420 HP.  The torque is supposed to be under 440 ft/lbs, at the crank.
Hope that helps.
 
Forgot about the style of supercharger; it is a roots style supercharger, which installs on top of the engine.
 
silly question, did you beef up the tranny and the rear end?

If he has an 09, I wonder if the 6l80e will be enough? The 6.2 in the 09 escalade puts out 402HP 417TQ with the same trans, so I would think he would be right on that "line"

HD trailering with the trans cooler would probably be a big help in being able to keep the stock trans as well.
 
I did add a transmission oil cooler.  For the differential, I did nothing except a fluid change on the rear axle. 
I got the ECM back today, and did my first test run.  Everything is working well!  Just got to get used to the response.  :eek:
The outside temperature was 79F today.  Transmission temp. got up to 162F after a few runs, but cooled down to about 149F with regular driving.
I'll get a few pics up, if I can figure out how.

Thanks for your input, everyone.
 
Boy not sure it would be worth it then. the ATK 6.0l engine one of the other members is running runs 450/450 hp/torque naturally aspirated.   Cost is $4000 plus a core charge if you don't have a 6.0L.

When I talked to them they said some people have dynoed at close to 500 with that engine.

Please note, No intention of knocking what your doing. Anything we can do to make more power is really cool. Just trying to look at the cost and return of different options. Some of the blowers I have seen are supposed to put out 9PSI. Just not sure what would be the best way to go. Just surprised the ATK 6.0L engine is that much higher than a blown 5.3.

 
The SC companies seem to not push more than around 6 psi with their "stock" setups, I presume because the rest of the stock drivetrain would then have a decent chance of surviving at least 50K miles, plus the vehicle manufacturers also probably have about a 50% margin in fuel pump and/or injectors' capability.  Easy enough to put on different pullies to get higher boost levels, and hence higher power output potential, if other supporting mods are done.
 
enoniam, you have gone a similar route in the past.

Is this the type of setup you have done?
I might consider a blower like this myself if I get the chance knowing I want to go to something bigger later.

Also would a 6psi blower be a 6psi blower on a 6.0L or would it end up being more like a 4psi blower?

If you look at going to a bigger engine setup later would it be better to plan your injectors for a blown 6.0L or will they be too big for a 5.3?

Look forward to hearing how well this setup works out. Feeling a little better about the option moving forward.

Twin turbo sounds cool but takes up far too much room for my tastes.

Oh yea... And what about pictures? :)

I installed a centrifugal supercharger after doing a "largish" (for a 3-ton truck) cam and 3200 stall torque converter.  Both the cam and supercharger gave me more top end and I gave up just a bit on the bottom end.  Torque converter made that largely a non-issue.

I can't tell you for sure how much boost would change going from a 5.3 to a 6.0 but I think it really has more to do with the relative horsepower and torque ratings between the engines.  I know I was having a hard time seeing the boost level on my 5.3 that KY_Bob, the supercharger's previous owner, was seeing with his 5.3.  We both had aftermarket cams, but mine was bigger than his.  I would think it would be within the realm of the possible (and possibly most likely) that a 6 psi supercharger on a normally aspirated 300 horse engine would only give 4 psi on a normally aspirated 450 horse engine.

If I was 90% sure I was going to do a blown 6.0 later, given that you're probably going to spend probably something to close to $500 on a set of injectors, I'd get the larger ones for the 5.3, assuming it was going to need something larger than what is on it now.  The downside will be the same no matter the engine size - idle tuning potentially being harder.

I hear you on the twin turbos.  Unless you mount them under the truck they will take up a lot of room under the hood.  And if you mount them under the hood you generally need to use a pump to push the oil that has run through them back to the oil pan, although if I recall correctly I recently saw one on TV that didn't need to have a pump...
 
OK. I finally got pictures of my install.  I have to give thanks to JohnnieMo and MyBigToy, for their ideas on where to install my transmission oil cooler.  I installed the transmission oil cooler( I got a Derale) behind the front license plate bracket, and used an old piece of AC grill that I found at my folks' place.  I cleaned it up, cut it to fit, painted it, and used a license plate bracket to house it.  The rest of the pics are of the Supercharger installed.  It looks like OEM, and runs great.  I am still getting used to the response of this thing whenever I hit the accelerator pedal(which is too often at the present time).

Write "at" you all later.

Looks Great! I did some reading up on SC's and it sounds like this one is top of the line providing solid boost throughout the full range while allowing good mileage at cruising speeds.

I will be interested in hearing more about the drivability of your truck as you get used to it.

At this point I am thinking that a SC like this one bolted to a built 6.0l would be a monster.

So I am very interested in hearing about your experiences.

How long did they have to have your computer for? On their web site they mention a programming pack that just updates the program but maybe that is just for my '03.

For the programming of the ECM, it took about one week.  I shipped it on a Tuesday, using UPS, and I got it back the following Tuesday afternoon around 4pm.  (This was around a national holiday [Monday was Martin Luther King day] of the following week).  I think if I could have shipped it on Monday, I would have gotten it back by Friday of that week. 
I live in Louisiana, and Magnuson is located in Ventura, CA.  The shipping time may be different depending on where you live relative to Ventura, CA.
 
I love the cooler install.  It never occurred to me to use a license plate frame for that.  Very clever!  You'll find it does an amazing job at keeping the tranny cool.  I think I am around 75,000km on my Magnuson setup and not a lick of trouble to date.  It runs like stock, just a lot faster!
